Analysis
US tech IPOs have already topped 235 listings in 2026, roughly 2.6% ahead of the same point in 2025, and the pipeline shows no sign of thinning as the year enters its final stretch, per StockAnalysis's running 2026 IPO tracker. The second quarter alone set an all-time quarterly record at $104.8 billion raised, a mark driven overwhelmingly by one listing: SpaceX's June 12 debut at a $1.77 trillion valuation, the largest IPO ever completed.
That single data point reshaped what “big” means for the rest of 2026's pipeline. Before SpaceX, a $50 billion tech listing would have been a headline year-maker on its own; after it, bankers and investors are now measuring the next wave of AI-company IPOs against a trillion-dollar-plus benchmark that didn't exist as a real comparison point twelve months ago.
Two Trillion-Dollar Contenders, Four Months Apart
OpenAI is targeting a September listing, with CEO Sam Altman reportedly aiming for a valuation between $852 billion and $1 trillion, led by Goldman Sachs, Morgan Stanley and JPMorgan. Pulse has tracked OpenAI's IPO preparation since its confidential S-1 filing in May. The company pulls in roughly $2 billion a month in revenue and counts 50 million consumer subscribers alongside 9 million business users -- but it also loses more than a dollar for every dollar of revenue and doesn't expect profitability until around 2030, numbers that will draw far more scrutiny once they're in a public prospectus rather than reported secondhand.
Anthropic, meanwhile, is reportedly preparing an October listing, with the company expected to tell prospective investors its addressable market exceeds $30 trillion, per Dealroom's IPO tracking. Pulse has tracked Anthropic's compute buildout and valuation trajectory as it has climbed toward $965 billion ahead of that listing -- a mark that, like OpenAI's, would put Anthropic within range of SpaceX's record if investor demand matches the ambition of the pitch.
Why the Concentration Matters
Two of the three largest technology IPOs in history potentially pricing within about four months of each other is a genuinely unusual concentration for public markets to absorb. Historically, mega-cap tech listings have been spaced years apart -- Meta in 2012, Uber in 2019, Snowflake in 2020 -- giving markets time to digest each one before the next arrives. Two trillion-dollar-plus AI listings landing back-to-back tests both the demand side (can public markets absorb that much new supply of mega-cap tech equity in one stretch) and the comparison side (OpenAI and Anthropic will be priced directly against each other by every analyst covering both).
The bear case for this pipeline is straightforward and shouldn't be waved away by the SpaceX precedent: SpaceX's valuation rests on a business with actual profitable operations -- launch services, Starlink subscriptions -- layered under its Anysphere and xAI combination, while OpenAI and Anthropic are both pricing primarily on growth and TAM narrative against current unprofitability. A public market that absorbed SpaceX's trillion-dollar debut smoothly may still respond very differently to two consecutive AI-native listings without SpaceX's diversified, cash-generating base underneath the multiple.
For VCs and founders, the read-through is straightforward: exit liquidity for AI-adjacent portfolio companies is genuinely opening up at a scale that didn't exist eighteen months ago, but the September-October pricing of OpenAI and Anthropic will set the multiple every subsequent AI IPO gets measured against for at least the following year. A soft landing on either listing recalibrates every private AI valuation still marking up on growth alone.
