For three decades, the biggest IPOs were rare, generational events.
That just changed: SpaceX's June 2026 debut raised $85.7 billion, more than 3x the previous record, and it's only the first name in a pipeline set to rewrite this entire list.
Before these records fall, it's worth asking what the biggest IPOs of the last 30 years actually got right and why a record-breaking raise so often says nothing about what happens next.
Largest IPOs of All Time: Key Findings
- Record-breaking IPOs still need to prove they can sustain investor confidence. SpaceX's $85.7 billion debut nearly tripled Saudi Aramco's record, but then fell 47% below its peak and under its own offer price within six weeks.
- A bad opening day predicts almost nothing. SoftBank fell 14.5% on its debut, and Facebook spent over a year below its offer price. Day-one price action is noise, not signal.
- The business model outlasts the market it launches into. Visa raised $17.9 billion six months before Lehman collapsed and thrived anyway. Durability beats timing.
These Records Stood for Decades. 2026 Is Erasing Them
For more than 30 years, the largest IPOs in history have been generational events.
A telecom giant, a state oil company, and a Chinese eCommerce empire raised $15–25 billion and held records for years.
That era is ending. SpaceX's June 2026 listing raised $85.7 billion at an IPO price valuation near $1.77 trillion, more than 3x Aramco's long-standing record, and the largest IPO in history.
It's the first of a 2026 pipeline that includes Anthropic, Stripe, and OpenAI (reportedly weighing 2027), several eyeing valuations near or above $1 trillion.

A single year is already rewriting the all-time list.
Which is exactly why the history below matters. Before these records fall, here's what the biggest IPOs of the last three decades got right and what today's mega-listings can still learn from them.

A note on SK Hynix: SK Hynix has been publicly traded in Seoul since 1996, so its $26.5 billion Nasdaq transaction was a U.S. listing rather than the company's first-ever IPO.
It ranks here because it was a primary capital-raising offering of newly issued shares through underwriters, complete with a roadshow, book-building, and an offer price – structurally similar to an IPO.
1. SpaceX: The $85.7 Billion Debut That Shattered Every IPO Record
- IPO value: $85.7 billion (incl. greenshoe; $75 billion base)
- Shares sold: ~639 million Class A shares (555.6M base + 83.3M overallotment)
- Initial share price: $135
- Exchange: Nasdaq
- Valuation at IPO: ~$1.77 trillion
In June 2026, SpaceX raised $85.7 billion on the Nasdaq, making it the largest IPO in history. It priced at a fixed $135 per share the night of June 11 and began trading June 12 under the ticker SPCX, initially raising $75 billion.
Underwriters Goldman Sachs and Morgan Stanley then exercised the deal's "greenshoe" overallotment, buying an extra 83.3 million shares to lift total proceeds to $85.7 billion.
The debut delivered, then didn't, then partly recovered. Shares opened at $150, closed day one at $161.11, and ran to an all-time high of $225.64 on June 16, briefly making Elon Musk the world's first trillionaire.
By late July, the stock had fallen roughly 50% from that peak to an all-time low near $105, trading below its own $135 offer price.
Then came the two events the whole year had been building toward. SpaceX reported its first public quarterly results on August 4: revenue of $7.81 billion, up 92% year over year and ahead of the $6.93 billion expected, with the net loss narrowing to $541 million from $1 billion.
Two days later, on August 6, its first lockup expired, and 911.5 million insider shares became sellable, more than doubling the public float from 4.9% to 11.8% of shares outstanding. The feared flood never arrived.
The stock rose 6.1% on the unlock day and gained another 15.8% on August 7 to close at $133.11, back within a couple of dollars of its IPO price.
Company Performance
Unlike the others on this list, SpaceX has only weeks of public-market history, but those weeks have already delivered a verdict on the debut price, if not on the business.
The offering itself was a triumph of demand: orders reportedly topped $250 billion, oversubscribed roughly 3.5-4x, and underwriters exercised the full greenshoe. What followed was a repricing.
- Market cap: ~$1.74 trillion (August 7, 2026), recovered from a late-July trough near $1.4 trillion but still below the ~$2.77 trillion June peak.
- Profitability: Q2 2026 net loss narrowed to $541 million from $1 billion a year earlier on $7.81 billion in revenue. Adjusted EBITDA jumped 191% to $3.5 billion, while CapEx surged more than sixfold to $18.37 billion, including $15.83 billion for AI.
- Balance sheet: The IPO added roughly $75 billion to SpaceX's pre-IPO cash position of $15.85 billion, giving it roughly $91 billion in cash after the offering.
- Stock performance: $133.11 as of August 7, versus a $135 IPO price and a 52-week range of roughly $105-$225.64. Analysts remain split to an extreme: HSBC and Argus both initiated at hold (HSBC at a $115 target) against a consensus 12-month target near $237.
What SpaceX Got Right
- It opened the deal to retail. SpaceX reserved roughly 30% of the offering for individual investors, far above the typical 10%, broadening demand and turning the listing into a public event rather than an institutions-only allocation.
- It priced to pop. The fixed $135 price came in below some market expectations, leaving room for a ~19% first-day gain instead of risking a flat, Aramco-style debut. With the stock holding well above $135, underwriters exercised the greenshoe in full.
- It sold scarcity. A tight public float (around 4%) and a narrative built on Starlink's moat and AI-infrastructure ambition concentrated demand into a small pool of shares.
The caution worth keeping in mind is that a record raise marks a moment of strength but does not guarantee its future.
With losses accelerating, ~82% voting control concentrated in Musk, and governance concerns raised publicly before the bell, SpaceX is now the live test of whether the biggest IPO ever becomes one of the best.
2. SK Hynix: The $26.5 Billion Debut That Broke a 12-Year Record in a Down Market
- IPO value: $26.5 billion
- Shares sold: 177.9 million ADRs (each representing one-tenth of a Seoul-listed common share
- Initial share price: $149 per ADR
- Exchange: Nasdaq (ticker: SKHY)
- Valuation at debut: ~$1.25 trillion
In July 2026, South Korean memory chipmaker SK Hynix raised $26.5 billion in the largest US listing ever by a foreign company – topping Alibaba's 2014 record – and the second-largest capital-raising offering in history, behind only SpaceX's $85.7 billion a month earlier.
Important note: SK Hynix has traded in Seoul since 1996; this was its first offering on a US exchange. It's a capital-raising debut that market convention counts as an 'IPO'.
It priced 177.9 million American depositary receipts at $149 each on July 9 and began trading on July 10, opening above $170 and closing its first session at $168.01, up 13%.
What makes the deal remarkable is when it happened. SK Hynix priced into the teeth of a global AI selloff, which was the same week South Korea's KOSPI was halting trading and chip stocks were being sold off worldwide, and was still more than seven times oversubscribed, drawing roughly $171 billion in orders for a $26.5 billion deal.
Company Performance
Unlike most entries on this list, SK Hynix's US listing is only days old, but the company behind it has a 30-year public track record in Seoul, and it arrived on the Nasdaq at the peak of the sharpest earnings run in its history.
- Market cap: ~$1.25 trillion at its Nasdaq debut (July 2026), placing it among the world's most valuable semiconductor companies.
- Profitability: Q1 2026 net profit up 398% year over year with operating margins above 70% — and industry researchers project 75–80% average operating margins for the top three memory makers through the current upcycle, expected to run at least through 2027.
- Market position: The dominant supplier of high-bandwidth memory (HBM), with a 56.4% global HBM share, an 18.5% NAND share, and the world's #2 position in DRAM, deeply embedded in Nvidia's supply chain.
- Stock performance: The ADR surged from its $149 offer price to $177 intraday before retreating toward $160 within days.
What SK Hynix Got Right
- It sold profits into a market punishing hype. Weeks after investors began repricing loss-making AI companies, SK Hynix offered recognized revenue, high margins, and contracted AI demand. The 7x oversubscription was the market voting for proof over projections.
- It gave US investors access to the world's leading HBM supplier through a U.S.-listed security. Before this listing, Micron was the only pure-play memory stock on a US exchange.
- It raised capital while demand was strongest. The $149 ADR price sat roughly 5% above its own Seoul shares, and the deal still drew ~$171 billion in orders. The $26.5 billion was banked at the top of demand.
The aftermarket, though, told the oldest IPO story at record speed. Shares peaked at $177 intraday, fell below their $170 opening price before the first session even closed, and slid toward $160 within days — a fade SpaceX took nearly a month to match.
Analysts pinned it on valuation rather than the business, as HBM demand still outruns supply, and major hyperscalers are projected to spend well over $1.5 trillion on AI infrastructure across 2026–27.
Then it bounced back. On July 31, SK Hynix closed nearly 30% higher in Seoul, its best day on record, as the KOSPI posted its largest one-day gain ever (+17.9%), fueled by blockbuster Microsoft and Amazon earnings. Its U.S.-listed shares also recovered to around $149 — back to their IPO price.
3. Saudi Aramco: The $25.6 Billion Listing That Rewrote the Foreign Listing Record
- IPO value: $25.6 billion
- Shares sold: 3 billion (1.5% of total shares)
- Initial share price: SAR 32 ($8.53)
- Exchange: Tadawul (Saudi Stock Exchange)
- Valuation at IPO: $1.7 trillion
Until June 2026, the largest IPO of all time was Saudi Aramco, which raised $25.6 billion (up to $29.4 billion with the over-allotment) on Saudi Arabia's Tadawul exchange in December 2019.
But the headline number hides how close the deal came to disappointing.
Aramco originally floated the idea of raising up to $100 billion for 5% of the company, which would have valued it at $2 trillion. International investors balked, citing oil-price volatility, governance and legal risks, and geopolitical fallout, including the Khashoggi affair.
Rather than force the issue, Riyadh scaled the deal back, listed just 1.5% of the company on its domestic Tadawul exchange, and leaned heavily on local and regional investors to get it done.
The result was a record-breaking raise at a $1.7 trillion valuation: short of the original ambition, but a success on the terms that mattered.
Crucially, the listing wasn't just about capital: it was the centerpiece of Crown Prince Mohammed bin Salman's Vision 2030 plan to diversify the Saudi economy beyond oil.
Company Performance
Years later, Aramco remains one of the most valuable companies on earth.
Its fortunes rise and fall with global oil prices and OPEC+ production decisions rather than compounding like a tech stock.
- Market cap: 6.62T SAR (~$1.8 trillion) (2026), still one of the ten most valuable public companies in the world.
- Profitability: $104.7 billion net income for FY2025, more than Apple, Microsoft, and Alphabet typically earn in a year.
- Dividends: $85.5 billion distributed to shareholders in 2025, among the largest dividend payouts of any company in the world, and a 3.5% increase marking Aramco's fourth straight year of dividend growth.
- Stock performance: 27.90 SAR (~$7.44) as of late May 2026, trading near the top of its 52-week range and tracking OPEC+ production decisions closely.
What Aramco Got Right
Looking back, several patterns explain how the deal became the biggest in history despite the doubts surrounding it:
- It adjusted ambition to match real demand. Rather than chase the $100 billion headline and risk a failed listing, Aramco cut the deal to $25.6 billion and a 1.5% float.
- It listed where the appetite was. Facing international skepticism, Aramco leaned on its domestic Tadawul exchange and regional investors instead of forcing a foreign listing on unfavorable terms.
- It turned its strengths into the story. Positioning itself as essential to global energy stability, Aramco offset valuation and geopolitical doubts with its undeniable scale and centrality to world oil.
4. Alibaba: The $21.8 Billion Debut That Became the Largest US IPO Ever
- IPO value: $21.8 billion
- Shares sold: 368 million (14.9% of total shares)
- Initial share price: $68
- Exchange: New York Stock Exchange (NYSE)
- Valuation at IPO: Approximately $231 billion
In September 2014, Alibaba Group Holding Limited raised $21.8 billion on the NYSE. It was the largest IPO in history at the time and remains the largest IPO ever by a company listing in the United States, even though Alibaba is Chinese.
The debut was a spectacle. Shares priced at $68 opened at $92.70 and closed up 38% on day one, valuing the company at roughly $231 billion and briefly making founder Jack Ma the richest person in China.
But the bigger story was where Alibaba chose to list. Rather than go public in Hong Kong, its natural home market, Alibaba opted for New York.
This was partly because Hong Kong's rules wouldn't accommodate its partnership governance structure, and partly to tap the deeper, more liquid US capital markets.
Company Performance
The years since have been far bumpier than that opening day suggested.
Alibaba has moved through Beijing's regulatory crackdown, a record antitrust fine, and a broad restructuring. It’s now repositioning around AI and cloud rather than eCommerce alone.
- Market cap: $298 billion (May 2026), up modestly from its IPO valuation but well below its 2020 peak above $800 billion.
- Profitability: RMB 102.1 billion (~$14.8 billion) net income for the fiscal year ending March 2026.
- Dividends: Alibaba paid its first-ever dividend in 2024, with a current annual dividend near $1.05 per share.
- Stock performance: $124–126 per share in late May 2026, within a 52-week range of roughly $104–193.
What Alibaba Got Right
A few decisions explain why the listing became a landmark, and how Alibaba has stayed standing through a turbulent decade:
- It listed where its goals fit, not where it was expected to. Alibaba chose the NYSE over Hong Kong to accommodate its governance structure and tap deeper capital, maximizing global visibility.
- It reinvested before rewarding shareholders. For a decade, Alibaba poured profits into logistics, expansion, and innovation rather than dividends, waiting until 2024 to start paying out.
- It diversified ahead of the pressure. As US–China tensions and domestic regulation mounted, Alibaba expanded beyond eCommerce into cloud and AI, building the second growth engine now carrying the stock.
5. SoftBank: The $21.3 Billion Spin-Off That Set Japan's IPO Record
- IPO value: ¥2.65 trillion (approximately $21.3 billion)
- Shares sold: More than 1.76 billion
- Initial share price: ¥1,500
- Exchange: Tokyo Stock Exchange
- Valuation at IPO: Approximately ¥7.18 trillion
In December 2018, SoftBank Group Corp. spun off its Japanese telecom unit, SoftBank Corp., in an IPO that raised $21.3 billion. It was the largest in Japan's history and, at the time, the biggest IPO anywhere since Alibaba in 2014.
This listing was, overall, a financing maneuver. Founder Masayoshi Son took the mature, cash-generating mobile unit public to free up capital for the parent company's real ambition: global technology investing through the Vision Fund.
The debut was rocky, with shares falling about 14.5% on day one. It was one of Japan's worst major IPO openings, as retail investors questioned the price after an aggressive marketing push.
Yet the deal did exactly what Son needed: it converted a slow-growth telecom into a war chest for higher-risk bets.
Company Performance
The split produced two very different companies. The listed entity, SoftBank Corp., has settled into a stable, dividend-focused carrier, while its parent funnels capital into AI and frontier tech.
- Market cap: ~¥10.2–10.7 trillion (~$70 billion) as of May 2026, well above its IPO valuation, reflecting steady growth as a core Japanese carrier.
- Profitability: ¥11 earnings per share, positioning it as a mature, profitable operator rather than a high-growth play.
- Dividends: A dividend yield near 4%, sustained for eight consecutive years, among the more reliable payouts on the Tokyo exchange.
- Stock performance: ¥217 per share in late May 2026, up about 66% since its 2018 IPO, once dividends are included.
SoftBank Group continues to invest heavily in AI, including a multibillion-dollar commitment to Stargate, an AI-infrastructure venture with OpenAI and Oracle, a strategy the 2018 IPO was designed to fund.
What SoftBank Got Right
The listing looked underwhelming on day one, but the logic behind it explains why it still set a record:
- It turned a mature asset into growth capital. SoftBank took its steady, cash-generating telecom public specifically to free up funds for higher-risk tech investing, rather than letting a slow-growth unit sit idle.
- It spread its bets across sectors. Through the Vision Fund, the capital flowed into AI, eCommerce, biotech, and fintech, reducing dependence on any single market or region.
- It played a long game through volatility. Despite a rocky debut and swings in quarterly results, SoftBank held to a multi-year technology-investment thesis rather than reacting to short-term market noise.
The Rest of the Top 10: Five More Record-Setting Listings
Beyond the top five, the rest of the list spans insurance, energy, tech, autos, and banking.
It’s a reminder that record-setting IPOs come from very different places, for very different reasons.
- NTT DoCoMo: $18.1 Billion (1998, TSE)
- Visa: $17.9 billion (2008, NYSE)
- AIA Group: $17.8 billion (2010, Hong Kong)
- ENEL: $16.6 billion (1999, Borsa Italiana)
- Facebook (Meta): $16 billion (2012, NASDAQ)
- General Motors: $15.8 billion (2010, NYSE)
6. NTT DoCoMo: $18.1 Billion (1998, TSE)
In October 1998, Japan's dominant mobile carrier, NTT DoCoMo, raised roughly $18.1 billion on the Tokyo Stock Exchange. This record stood as the largest IPO in the world for more than a decade.
The timing was everything. DoCoMo went public, controlling about 57% of Japan's cellular market, just as mobile adoption was exploding.
However, unlike the other companies on this list, NTT DoCoMo no longer trades as an independent public company.
In 2020, parent company NTT bought out the remaining shares in a ~¥4.3 trillion (~$40 billion) deal and delisted DoCoMo from the Tokyo Stock Exchange in December 2020, absorbing it fully back into the group.
DoCoMo remains NTT's core consumer mobile and "smart life" business, and is expanding through acquisitions such as its 2025 purchase of a stake in CARTA Holdings.
7. Visa: $17.9 billion (2008, NYSE)
Visa's March 2008 IPO was the largest in U.S. history at the time and one of the most counterintuitive, launched six months before Lehman Brothers collapsed.
It worked because Visa doesn't lend money. While the banks around it were drowning in defaults, Visa collected a fee on every card swipe regardless of whether borrowers could repay.
Investors recognized a toll booth, not a balance sheet, and bought in despite the surrounding panic.
That structural advantage has compounded ever since. Visa's market cap has grown roughly 35x from its IPO-day value, with $20.1 billion in net income on $40 billion in revenue for fiscal 2025, one of the clearest examples on this list of a business model that outlasted the market it launched into.
8. AIA Group: $17.8 billion (2010, Hong Kong)
AIA's $17.8 billion listing was born from someone else's crisis. Its parent, the American insurer AIG, was selling assets to repay a 2008 financial-crisis bailout, and after a planned $35.5 billion sale to Prudential collapsed, it spun AIA off instead.
The Hong Kong debut is still the city's largest ever. It re-established AIA as an independent pan-Asian insurer, capitalizing on the region's fast-growing middle class.
The bet aged well: riding decades of Asian economic expansion, AIA has since grown into a roughly 849.9 B HKD (~$115 B) company and a dominant force in life insurance across the continent.
9. ENEL: $16.6 billion (1999, Borsa Italiana)
ENEL's $16.6 billion offering was less a startup story than a sale of state silver.
The Italian government floated roughly a third of its national power utility — Europe's largest IPO of the 1990s and the biggest privatization in Italian history — while keeping control, raising cash and inviting public investment without surrendering a strategic asset.
ENEL used its newfound market access to expand aggressively abroad and, later, to pivot hard into renewables. Today it remains one of Europe's largest power and clean-energy operators, serving tens of millions of customers across nearly 30 countries.
10. Facebook (Meta): $16 billion (2012, NASDAQ)
Facebook's $16.0 billion debut is famous for going wrong.
NASDAQ's systems glitched on launch day, trades were delayed and disputed, and the stock spent more than a year below its $38 offer price as investors questioned whether Facebook could make money on mobile. It could.
By building a mobile-first advertising machine, Facebook turned the most-mocked tech IPO of its era into one of the best-performing.
Parent company Meta Platforms is now worth around $1.52 trillion, proof that a disastrous opening day says almost nothing about the long run.
Why a Record IPO Doesn't Guarantee Long-Term Success
It's tempting to read a list like this as a ranking of winners. It isn't.
The size of an IPO measures one thing: how much capital a company raised on a single day. That number says surprisingly little about what happens next.
The companies above make the point better than any theory could:
- SoftBank Corp. fell about 14.5% on its first day of trading, one of the worst major-IPO debuts in Japanese history.
- Facebook spent more than a year below its $38 offer price as investors doubted it could make money on mobile.
A record raise can also mark a peak rather than a beginning:
- Saudi Aramco held the all-time record for seven years and remains hugely profitable, but its stock tracks oil prices and OPEC+ decisions rather than compounding the way a high-growth tech company does.
- SK Hynix fell below its opening price before its first day even closed, slid further in the July chip rout, then posted its best single session on record.
- SpaceX opened 19% above its offer price, ran 67% higher to a $2.77 trillion peak, fell roughly 50% from that high to below its own offer price, then recovered almost all of it in two sessions once its first earnings and first lockup passed without disaster.
For these examples, day-one demand only measured one day's appetite, but everything since has been the market arguing with itself.
So what actually separates a great IPO from a merely large one? Not the headline figure, but what sits underneath it:
- A durable business model. Visa raised $17.9 billion during a financial crisis and thrived anyway, because it didn't carry credit risk. The model, not the timing, carried it.
- A reason to hold, not just to buy. The strongest performers gave investors something beyond the debut: Visa's compounding network, Aramco's consistent dividends, and Alibaba's eventual pivot to cloud and AI.
- Room to adapt. Markets, regulation, and technology all shift after the bell rings. The companies that endured (e.g., Alibaba through Beijing's crackdown, GM after bankruptcy) were the ones that could change.
The new record-holder made this article's point faster than any entry before it. SpaceX opened 19% above its offer price, ran 67% higher to a $2.77 trillion peak, then gave all of it back and more, trading 47% below that high and under its own $135 offer price within six weeks. Nothing about the record $85.7 billion predicted either leg.
SpaceX is simultaneously a profitable aerospace business, a money-losing AI lab, and a satellite internet provider with no real competitor, bundled together under a single person controlling more than 82% of the vote.
Investors who buy SPCX are making a bet on all three at once, with limited ability to influence any of them. The IPO was historic. Whether it was a beginning or a peak is a question that 2026's public markets are only starting to answer.
Largest IPOs of All Time: Final Thoughts
What unites these companies is a single moment when scale, story, and timing aligned well enough to pull in tens of billions of dollars at once.
That alignment used to be rare enough that enormous IPOs happened only a handful of times in a generation. 2026 broke the pattern: two of the three largest raises in history landed within 28 days of each other, and both then whipsawed 40% or more in either direction within two months
The verdict arrives quarter by quarter, and for both of these it has only just started.
The names and figures at the top of this list will almost certainly change, and soon. The forces that put them there — and the gap between raising money and lasting — won't.

Largest IPOs of All Time FAQs
1. What was the biggest IPO of 2025?
Medical-supply giant Medline was the largest IPO of 2025, raising about $6.3 billion on the Nasdaq in December at a valuation near $37 billion.
It edged out a busy field that included AI-infrastructure firm CoreWeave ($1.5 billion, and the largest U.S. tech IPO since 2021), LNG exporter Venture Global ($1.75 billion), and buy-now-pay-later firm Klarna ($1.37 billion).
2. What's the difference between the amount raised and the IPO valuation?
These two figures are often confused. The amount raised is the cash a company actually collects by selling shares, which is what ranks IPOs. The valuation is the company's total market worth at its offer price, which is usually far larger because only a slice of the company is sold.
Saudi Aramco illustrates the gap perfectly: it raised $25.6 billion but was valued at about $1.7 trillion, because it floated just 1.5% of its shares.
3. Why don't more huge companies go public sooner?
Staying private lets companies raise large sums without public-market scrutiny, quarterly reporting pressure, or disclosure requirements. Deep private funding (from venture capital and sovereign funds) has let companies delay IPOs for years.
4. Which industries produce the biggest IPOs?
Technology, telecommunications, financial services, energy, and insurance account for most of the largest IPOs ever recorded.
These sectors tend to dominate because they operate at massive scale, generate significant cash flow, or sit at the center of long-term economic trends like digital transformation, global energy demand, and financial infrastructure growth.
5. Do the biggest IPOs make the best investments?
Not reliably. The size of a raise reflects how much capital a company collected on one day, not its future returns — Visa and Facebook compounded enormously, while others stagnated or were delisted. IPO size and long-term performance are largely unrelated.
6. What is the biggest IPO ever?
As of June 2026, SpaceX holds the record. Its Nasdaq debut raised $85.7 billion, at a valuation near $1.77 trillion, more than 3x Saudi Aramco's $25.6 billion, the prior record-holder.
SK Hynix's $26.5 billion Nasdaq debut in July 2026 now ranks second.
7. Does a cross-listing count as an IPO?
By market convention, yes, if it raises capital.
SK Hynix had traded in Seoul since 1996 when it listed on the Nasdaq in 2026, but its U.S. debut was a primary capital-raising offering: newly issued shares sold through underwriters following a roadshow, book-building, and formal offer pricing.
Many financial outlets therefore classify it as a U.S. IPO or foreign IPO, even though it was not the company's first-ever public offering.
