For three years, one of the most reliable signals of corporate confidence went quiet. After a record-shattering 2021, the market for initial public offerings — the moment a private company first sells shares to the public — froze almost solid. Then, in the first half of 2026, the numbers jumped in a way no one could ignore. Global IPO proceeds rose 210% year over year, with 509 companies raising a combined US$193.6 billion [source: EY Global IPO Trends, 2026]. In the United States, a single listing — SpaceX, which debuted on June 12, 2026 — raised roughly US$86 billion, making it, by news accounts, the largest IPO in financial-market history [source: Fortune, 2026].
So the window is open again. But that word — "open" — needs a careful reading, because the same data that shows a surge in money raised also shows something quieter: fewer companies actually went public. This is a story about why the listing window shut, why it is creaking open now, and why "record proceeds" is not the same thing as a full recovery. It is about public equity markets — companies selling stock to ordinary investors — and not about the private-credit or private-equity booms that have their own separate stories.
From record to freeze
To understand the reopening, start with the slam. 2021 was the biggest year for IPOs the world had ever seen: 2,341 companies went public globally, raising US$428.9 billion [source: World Economic Forum, 2022]. Money was cheap, the pandemic had unleashed pent-up demand, and hundreds of blank-check SPAC vehicles piled on top. It was, in hindsight, a peak built on unusually easy conditions.
Then those conditions reversed, fast. Starting in March 2022, the U.S. Federal Reserve raised its benchmark interest rate from roughly 0.25% to about 5.5% by July 2023 — the fastest hiking cycle in about 40 years [source: Kroll, 2024]. Higher rates make the far-off profits of young, growth-oriented companies worth less today, and they give investors safer places to park cash. The IPO market responded by seizing up: 2022 and 2023 were the weakest years for new listings since the global financial crisis, with U.S. IPO proceeds collapsing by roughly 94% from the prior year [source: World Economic Forum, 2022]. Companies that had planned to debut simply waited.
It is worth being precise about the relationship here. Rates, risk appetite, and IPO activity all moved together, and it is fair to say the freeze coincided with the sharpest tightening in decades. But interest rates are not a single lever that mechanically opens and shuts the market; valuations, the health of the pipeline, and investor mood all move at once. The honest framing is association, not a proven one-way cause.
The numbers behind the 2026 revival
By 2026 the picture had turned. EY's tally of global activity found 509 IPOs in the first half of the year raising US$193.6 billion — proceeds up 210% from the same period a year earlier [source: EY Global IPO Trends, 2026]. In the United States, the rebound in money raised was even steeper: proceeds reached about US$128 billion through June 30, a 646% jump year over year [source: Fortune, 2026]. The number of billion-dollar-plus U.S. deals tripled, from four in the first half of 2025 to twelve in the first half of 2026 [source: EY Global IPO Trends, 2026]. On proceeds alone, the first half of 2026 already ranked as one of the strongest stretches on record.
Underneath the aggregate, momentum concentrated heavily in one theme: artificial intelligence and the physical infrastructure around it — semiconductors, power, data centers, robotics. EY's own read was cautiously upbeat, noting that "what makes this recovery different from the false starts of recent years is its breadth" [source: EY Global IPO Trends, 2026]. That phrase — "false starts" — is a reminder that the market has teased a comeback before and stalled.
The mega-deal distortion: proceeds up, volume down
Here is the fact the headline number hides. In the same first half of 2026 when U.S. proceeds jumped 646%, the number of U.S. IPOs actually fell 35% — 72 listings versus 111 a year earlier [source: Fortune, 2026]. Globally the divergence was gentler but pointed the same way: proceeds up 210%, deal volume down 7% [source: EY Global IPO Trends, 2026]. More money, from fewer companies.
The reason is concentration. SpaceX's roughly US$86 billion raise, at a market value near US$1.8 trillion, accounts for the majority of all U.S. IPO proceeds in the first half of the year on its own [source: Fortune, 2026]. Strip out one historic deal and the "record" looks far more modest. This is the layer that careful readers should hold onto: a surge in dollars raised, driven by a handful of giants, is a real sign of thawing appetite — but it is not the same as a broad reopening in which hundreds of ordinary companies find willing buyers. Proceeds and volume are telling slightly different stories, and only one of them is unambiguously loud.
Who actually went public
If 2026's proceeds were skewed by giants, it was 2025 that quietly reopened the door. Renaissance Capital counted 202 U.S. IPOs in 2025, a four-year high in new issuance, even as a full rebound was held back by tariff volatility, an extended government shutdown, and a fourth-quarter pullback in AI stocks [source: Renaissance Capital, 2025]. The names that tested the water were a fair cross-section of the moment:
- CoreWeave, an AI cloud-computing provider, listed on Nasdaq on March 28, 2025 at US$40 a share, raising about US$1.5 billion at a roughly US$23 billion valuation — described by CNBC as the biggest U.S. tech IPO since 2021 [source: CNBC, 2025]. The proceeds and valuation are the company and its underwriters' figures; notably, the stock closed its first day flat, a market verdict that was cooler than the fanfare.
- Circle, the issuer of the USDC stablecoin, priced above its range at US$31 on the NYSE on June 5, 2025 and raised about US$1.1 billion; its shares then surged roughly 168% on debut, trading so wildly they were halted several times [source: CNBC, 2025].
- Figma, a design-software company, raised about US$2.4 billion in its July 2025 offering and opened sharply above its US$33 price [source: Quartr, 2025]. Klarna, the buy-now-pay-later lender, raised about US$1.9 billion [source: TipRanks, 2025].
Two cautions travel with every name on that list. First, the eye-catching valuations and proceeds are figures set by the company and its bankers at the moment of sale, not independent appraisals. Second, a big first-day pop is a market event, not proof the business is sound — and the broader IPO class of 2025 underperformed the market it joined. Renaissance's IPO index ended the year up just 5%, well behind the S&P 500's 16% [source: Renaissance Capital, 2025].
Why they waited: the pull of staying private
The freeze explains why companies couldn't easily list from 2022 to 2024. But a deeper, slower shift explains why so many chose not to, even as conditions improved: it has simply become easier to stay private, and for longer. Thirty years ago the United States had close to 8,000 public companies; today it has under 4,000 [source: CNBC, 2026]. The median company going public was about 8 years old in the mid-1990s; by 2024 that had stretched to 14 years, and 12 in 2025 [source: CNBC, 2026].
The mechanism is money. Late-stage private companies can now raise billions from venture and private-capital investors without submitting to the disclosure, scrutiny, and quarterly pressure of public markets [source: CNBC, 2025]. Secondary marketplaces such as Forge Global and EquityZen let early employees and investors cash out some of their shares without waiting for an IPO — removing one of the traditional reasons to list at all [source: CNBC, 2025]. In this world, an IPO is no longer the beginning of a company's growth story; it is closer to the exit. That structural gravity is why even a friendlier 2026 market is drawing fewer, larger, and more mature companies rather than a flood of young ones.
Not just an American story
The reopening is easy to read as a Wall Street event, but the busiest venue has been in Asia. Hong Kong's exchange, HKEX, ranked as the world's top IPO market in 2025, raising about US$36.0 billion across 114 listings — a 63% jump in the number of deals and more than double the prior year's proceeds [source: EY, 2025]. The momentum carried into 2026: HKEX raised about HK$210.2 billion (roughly US$26.8 billion) in the first half, up 92% year over year, again leading the global rankings ahead of the U.S. exchanges in second and third place [source: China Daily, 2026]. Across the Asia-Pacific region, EY counted 247 IPOs raising US$46.8 billion in the first half of 2026, up 6% in volume and 60% in value [source: EY Global IPO Trends, 2026]. Wherever it is measured, the thaw is uneven — strong in some regions, still frozen in others, with the Middle East and North Africa seeing IPO numbers fall about 80% amid regional conflict [source: EY Global IPO Trends, 2026].
Is the window really open?
The most useful way to hold all this is as a genuine but fragile reopening, not a declared recovery. The bullish case, argued by firms including General Atlantic, is that the second half of 2026 becomes a rebalancing — the moment discounts narrow and mid-cap companies in overlooked sectors finally test the market, spreading the action beyond a crowded handful of AI and chip trades [source: Fortune, 2026]. The sectors most often named for that broadening are advanced manufacturing, defense, energy, and AI infrastructure [source: Fortune, 2026].
The cautious case sits in the same data. Proceeds are concentrated; volume is down; the 2025 cohort lagged the market; and one revival signal worth watching warily is the SPAC — the blank-check vehicle whose 2021 excess left years of losses. SPAC issuance more than doubled in 2025 from the year before, which is either a sign of returning risk appetite or an echo of the last bubble, depending on how it plays out [source: Renaissance Capital, 2025]. A market whose "record" rests on a single US$86 billion listing has not yet proven it can carry hundreds of ordinary companies to a good outcome.
What to watch
A few concrete signals will show whether the window is truly open or merely ajar. First, watch whether volume catches up to proceeds — a real recovery needs many companies listing, not just a few giants; if the count of deals climbs through late 2026, the reopening is broadening [source: Fortune, 2026]. Second, watch the sectors: if advanced manufacturing, defense, and energy names price well, money is rotating out of the narrow AI trade and into a healthier calendar [source: Fortune, 2026]. Third, watch how the class of 2025 and 2026 actually trades a year on — post-IPO performance, not debut-day pops, is what convinces the next wave of founders that going public is worth it, and the early scorecard has been mixed [source: Renaissance Capital, 2025]. Fourth, keep an eye on the structural pull of private capital and secondary markets; as long as companies can raise billions and grant liquidity without listing, the public market will keep drawing more mature entrants and fewer young ones [source: CNBC, 2025].
The balanced read is neither "the IPO boom is back" nor "it's all one deal." The measured evidence says something narrower: after the fastest rate-hiking cycle in a generation slammed the window shut, a mix of steadier conditions, AI enthusiasm, and a backlog of companies that waited too long has pried it open again — most visibly in a few enormous listings, most durably in whether the many smaller ones follow. Read the volume, not just the headline dollar figure.
