Wall Street is bracing for one of the busiest stretches of stock market debuts in its history. Elon Musk’s SpaceX has just listed at a valuation of roughly $1.8 trillion, and AI heavyweights Anthropic and OpenAI have both filed confidentially for US listings expected later this year. For investors, it is a moment of plenty. It’s a chance to buy into some of the most closely watched companies on the planet the day they go public.
But for smaller companies hoping to make their own move into public markets in 2026, that same frenzy is becoming a problem. When a handful of trillion-dollar names dominate every headline, research note, and roadshow conversation, there is simply less attention, and less capital, left over for everyone else. Out of that squeeze, an old and once-discredited tool of corporate finance is quietly finding new life. Namely, the SPAC.
A Side Door Back onto Wall Street
A Special Purpose Acquisition Company, or SPAC, is essentially a shell company with no real business of its own. It lists on a stock exchange purely to raise a pool of cash, which then sits in trust while its sponsors hunt for a private company to merge with. Once a target is found, and shareholders approve the deal, the private company effectively becomes public by stepping into the shell, skipping the traditional IPO roadshow altogether.
That structure makes SPACs attractive in exactly the kind of environment now taking shape. Michael Ashley Schulman, a partner at Cerity Partners, frames it simply: a parade of mega-IPOs can make life harder for smaller issuers, since giant names soak up the headlines, the analyst coverage, and a large share of the capital that would otherwise be spread more evenly. A SPAC offers, what he calls, a quick side entrance onto public markets, one that does not require competing head-on with SpaceX or OpenAI for investor mindshare.
SPACs were the breakout story of the pandemic years, when hundreds of blank-cheque vehicles rushed to list, flush with cash and short on judgement. Many later struggled to find decent acquisition targets, rushed into weak mergers just to avoid returning money to investors, or saw the companies they took public deliver disappointing returns. The reputational damage was severe enough that, for a while, ‘SPAC’ became something close to a dirty word in finance circles.
The Numbers Tell the Story
That stigma now appears to be fading, and the data backs it up. Globally, 44 SPAC mergers have been announced so far in 2026, worth a combined $36.9 billion, up sharply from 33 deals worth $15 billion over the same period in 2025, according to Dealogic figures.
The pace of new SPAC listings has also picked up as around 145 blank-cheque companies went public in the United States in 2025, the highest annual total since the original 2021 boom, and another 107 have listed so far in 2026 through mid-June, nearly double the 57 recorded over the same stretch a year earlier.
Perhaps more telling is the dry powder sitting on the sidelines. As of mid-June, roughly 359 SPACs were holding a combined $56.8 billion in raised capital, all of it waiting to be matched with a deal, according to SPAC Research. Most of these vehicles operate on a clock of around two years from listing to find a target before they are forced to liquidate and hand the money back to investors. That built-in deadline is itself becoming a quiet driver of dealmaking, as sponsors under pressure to act look more seriously at targets they might once have passed over.
The market’s better-known faces are returning too. Chamath Palihapitiya, once nicknamed Wall Street’s ‘SPAC king’ for his run of high-profile deals during the boom years, is back in the mix, a sign of how far sentiment has shifted from the wariness of just a couple of years ago.
Who Stands to Benefit
Industry experts point to a fairly specific set of candidates for SPAC mergers this cycle. These include companies in energy, defence, critical minerals, nuclear power, space, and crypto, sectors where capital needs are large, timelines are long, and traditional IPO investors can be a harder sell. Smaller international firms looking for a foothold in US capital markets are also seen as natural fits.
Two recent deals illustrate the trend. In March, geothermal lithium developer Controlled Thermal Resources agreed to go public through a $4.7 billion SPAC merger, while Taiwanese battery maker ProLogium Technology struck its own blank-cheque deal worth $3.8 billion. Both are precisely the kind of capital-intensive, story-driven businesses that can struggle to get a fair hearing in a traditional IPO process crowded out by bigger names.
Michelle Gasaway, a partner in the capital markets practice at law firm Skadden, Arps, points to two practical advantages drawing companies back to SPACs. First is the flexibility to control timing, and the second the ability to negotiate a valuation directly with a sponsor rather than leaving price discovery to the whims of public market investors. For a company that does not want to gamble its valuation on the mood of the market during a single roadshow week, that certainty has real appeal.
Andrejka Bernatova, chief executive of Dynamix, who has raised about $630 million across her SPAC vehicles, notes that when investor sentiment is favourable, a SPAC merger can move in a matter of weeks, with capital raised in a matter of days. A traditional IPO, by contrast, can take months to prepare and remains vulnerable to being derailed by a sudden swing in markets, even late in the process.
A banking industry source told Reuters that conversations around potential SPAC mergers have picked up noticeably this year, particularly among companies valued below $3 billion that are now weighing both a SPAC and a conventional IPO as live options rather than treating the SPAC route as a fallback.
A More Mature Market, not a Repeat of 2021
What separates this resurgence from the boom-and-bust cycle of a few years ago is the texture of the activity itself. The 2021 wave was driven largely by sponsors raising new SPACs on the promise of a deal that often had not even been identified yet, a structure that left little room for scrutiny, and a great deal of room for disappointment.
This time, much of the momentum is coming from a backlog of vehicles that already raised their capital months or years ago, and are now under genuine time pressure to find a home for it before their charters expire. That changes the incentive structure as sponsors are not chasing headlines, they are racing a clock, and targets are being evaluated with the benefit of a market that has already lived through one round of SPAC failures.
Lukas Muehlbauer, a research associate at IPOX, captures the dynamic well. He expects some companies that might once have defaulted to a traditional IPO to instead look seriously at a SPAC merger, partly because so much existing capital is sitting in vehicles that need to close a transaction before liquidation forces their hand. That overhang of committed, deadline-bound money is arguably the single biggest structural difference between this cycle and the last one.
The Caveats Still Apply
None of this means the SPAC model has shed its old risks entirely. High redemption rates remain a genuine threat to deals as investors are free to pull their money out of a SPAC’s trust account once a merger target is announced, and several recent transactions have closed with far less cash than originally planned as a result. A company banking on a certain amount of merger proceeds can find itself with a smaller war chest than expected, right at the moment it needs capital most.
What is emerging looks less like the speculative free-for-all of 2021, and more like a leaner, more deliberate SPAC market, one built around vehicles with capital already raised, deadlines pressing them toward action, and a genuine gap in the market created by Wall Street’s biggest names crowding out everyone else.
For smaller companies eyeing a 2026 listing, that gap may be the opening they need. As Bernatova puts it, when the company is right and the market is there, a SPAC can simply be a more predictable way to go public, and strong appetite for the year’s mega-IPOs may end up doing as much to lift sentiment for SPACs as it does to overshadow them.
