OpenAI closed a $122 billion funding round in late March at an $852 billion post-money valuation, described at the time as the largest private funding round in history, before formally moving toward a public listing in June. The scale of the round alone reset expectations for what a late-stage AI financing could look like, and it came just two months before Anthropic’s own $65 billion raise pushed that rival past OpenAI’s valuation entirely.
OpenAI’s own disclosures put its 2026 annualized revenue in the $25 billion to $33 billion range, a large number in absolute terms but one that no longer clearly separates it from the pack the way it once did. Similarweb data shows ChatGPT’s monthly visits fell below a majority of the generative AI market for the first time in May, with Claude gaining the ground OpenAI lost, a symbolic shift for a company that has effectively been synonymous with consumer AI since ChatGPT’s 2022 launch.
The IPO push, meanwhile, sits inside a broader record year for AI capital. Crunchbase data shows global startup investment hit $510 billion in the first half of 2026, surpassing the entire $440 billion invested in all of 2025, with OpenAI and Anthropic together accounting for 43 percent of that total. Billion-dollar rounds have also started spreading beyond the foundation-model labs themselves into adjacent categories, AI infrastructure, defense tech, robotics, and energy for AI-scale compute, including a $1.75 billion strategic round for Houston-based energy startup Joulent and an $800 million Series C for AI-infrastructure company Together AI.
A public listing for OpenAI, whenever it lands, would be one of the clearest tests yet of whether public markets are willing to underwrite a company that has never demonstrated overall profitability at the scale its valuation implies. It would also arrive at a moment when Alphabet just lost roughly $225 billion in market value over a single AI product delay, a reminder of how sharply public investors are now punishing execution stumbles in this sector.
For Philippine investors and founders, an eventual OpenAI listing matters less as a curiosity and more as a signal. Filipino retail investors with access to US brokerage platforms will likely get a shot at the offering, but the bigger implication is upstream: if public markets validate frontier AI labs at these valuations, the pressure on every company building AI features, including Philippine startups pitching local investors, to demonstrate genuine AI differentiation rather than a thin wrapper around someone else’s API will only intensify.
The timeline for an actual OpenAI listing remains genuinely uncertain. Prediction markets tracking the question, including Polymarket, had roughly 73 percent of bettors wagering on a December 2026 IPO timeline as of early July, with only a small minority expecting the offering to launch before the end of that month. That uncertainty stands in contrast to SpaceX, which already completed its own mega-IPO on June 12, raising $75 billion in what was, briefly, the largest public offering in history. SpaceX’s successful debut gives OpenAI a recent data point on how public markets are pricing frontier technology companies with enormous valuations and comparatively thin profitability, for better or worse.
