The US IPO market is suddenly moving at the rambunctious pace bankers expected back in January. After a first quarter repeatedly interrupted by volatility spikes and geopolitical tensions, May is shaping up as a ‘take two’ moment for 2026.

“There’s a little something for everyone in this window,” said Daniel Polsky, ECM managing director and co-head of syndicate at William Blair.

Forty-seven IPOs have priced in the US so far this year, raising roughly USD 22.2bn, compared with USD 11bn at the same point last year, according to Dealogic. If all currently marketed offerings price successfully, more than 50 IPOs could be completed before the end of May, a volume the market did not reach until after Labor Day last year, Polsky said.

Unlike the more selective reopening seen earlier this spring, investors are now engaging with a wider range of sectors, structures, and risk profiles, bankers said.

“The number of launches may not quite rival 2021, but we’ve at least returned to the pace of activity we saw heading into the year,” said Matthew Kennedy, a market strategist at Renaissance Capital.

Despite ongoing geopolitical tensions, issuers have been encouraged by a strong corporate earnings backdrop and stabilizing equity markets.

“You’re seeing the strongest quarter of earnings growth since 2021,” Polsky said. “The broader market, with everything that’s being thrown at it from a geopolitical perspective, has been incredibly resilient.”

The market’s recovery has also been notably faster than last year’s, he said, helping investors regain confidence in new listings even during a crowded earnings season. The improving backdrop has translated into stronger aftermarket trading.

Kennedy said the number of IPOs generating double-digit gains has risen sharply compared with the first quarter, particularly across biotech, aerospace and defense, and AI infrastructure.

The strength of those debuts, alongside the looming SpaceX IPO in June, is encouraging companies to accelerate timelines while the market remains receptive. “There’s this rush right now to get out before June,” said Daniel Klausner, ECM managing director at Houlihan Lokey.

Buying for future growth

With March’s volatility wave fading, the market is expanding beyond a winner-take-all dynamic where only a handful of high-profile offerings attract demand.

Investors are increasingly willing to evaluate a broader range of sectors, business models, and, consequently, risk profiles. The widening appetite is particularly visible in the market’s renewed openness to earlier-stage businesses, a part of the IPO market that had largely remained shut since the collapse of the SPAC boom.

Some of the market’s strongest demand is now forming around IPO candidates with little revenue but exposure to AI infrastructure, nuclear energy, and future power demand.

This news service reported last week that Fervo Energy’s USD 1.3bn IPO is drawing significant investor interest driven by expected AI power demand, despite the company generating relatively little revenue. By Monday, the Houston-based geothermal company had raised its price range to USD 25-USD 26 per share from USD 21-USD 24.

There was also the success of X-Energy, which completed a more than USD 1bn IPO backed by Amazon and tied to rising data-center electricity demand.

A few years ago, many of these businesses would likely have pursued mergers with special purpose acquisition companies instead of traditional IPOs, Renaissance Capital’s Kennedy noted.

This raises the question of whether IPO investors are again becoming willing to take venture-style risk, provided the company is positioned around the right long-term growth theme.

“Investors are buying for future growth,” Kennedy said.

Traditional valuation frameworks are becoming harder to apply because investors are underwriting future infrastructure demand rather than current financial performance.

AI infrastructure and energy supply chains are at the center of that shift.

Matthew Wolfe, managing director and head of technology equity capital markets at William Blair, said investors are gravitating toward “picks and shovels” businesses that provide infrastructure and enabling technologies tied to AI demand, rather than trying to predict which large language model developer will ultimately dominate the market.

The approach gives investors exposure to AI growth while reducing dependence on a single winner-take-all outcome, he said. “You’re really looking to project out over a number of years,” William Blair’s Polsky added.

“Where is the money going to go and who are going to be the beneficiaries of everything that’s happening right now?”

Houlihan Lokey’s Klausner said some issuers are eager to establish themselves publicly before competitors enter the market, particularly in emerging AI and infrastructure categories where early public listings may shape how investors ultimately value and measure the broader sector.

Many of these companies are also expected to require substantial future capital investment, making public equity markets strategically important well beyond the IPO itself. Larger market participants are also tapping into investor demand for exposure to these themes. Cerebras Systems, a Sunnyvale, California-based AI chipmaker, has found strong interest during its roadshow and increased the price range for its IPO to USD 150-USD 160 per share.

Meanwhile, this news service also reported how Blackstone’s new REIT vehicle, which is IPO-bound despite not yet owning any assets, has become largely a bet on the quality of the sponsor and a way for investors to gain further exposure to the data-center universe.

Mark your calendar

While new launches have come in quick succession, this rush of issuance is colliding with increasingly tight disclosure timelines. Companies launching IPOs after mid-May generally need to include first-quarter financials in their prospectuses, forcing issuers to refresh disclosures quickly in a market where investors are demanding increasingly current information.

Many companies are already updating financials ahead of a 15 May staleness deadline, meaning issuers will need to refresh registration statements with 1Q26 data.

Meanwhile, SpaceX is expected to make further moves toward the launch of its roadshow shortly after Memorial Day weekend, with the first public filings, portions of which have already leaked, expected in the coming weeks.

Klausner noted how many prospective issuers who were ready by the end of 2025 and eyeing a launch later in 2026 have been accelerating their “go public” timelines. “We talk to a lot of clients who are pulling their activities forward.  These companies want to go out now because there’s a window,” he said.

Still, as the issuance calendar grows increasingly crowded, investor engagement has remained strong.

“Even in what’s been a very busy earnings season, we’re still getting a lot of mindshare from investors to look at these stories, really dig in and ultimately make decisions on a pretty accelerated timeframe,” William Blair’s Polsky said.
