Anthropic, OpenAI, and SpaceX eye simultaneous IPO window this summer
Three of the biggest names in AI and aerospace are reportedly preparing to go public together, marking a shift from the FAANG era to what some are calling the MANGOS cohort.

Anthropic, OpenAI, and SpaceX are all moving toward public offerings in the same timeframe, according to reporting this week. The convergence represents a rare moment when multiple decade-defining companies hit the IPO market simultaneously, each carrying valuations in the tens of billions and investor expectations shaped by years of private hype.
The timing puts unusual pressure on public markets. Anthropic's Claude models compete directly with OpenAI's GPT family, and both companies have raised billions in private capital at valuations that assume continued exponential growth. SpaceX, meanwhile, operates in a different vertical but shares the same investor base and the same appetite for moonshot narratives. All three have delayed public offerings longer than typical unicorns, building war chests and product traction in private before facing quarterly earnings calls.
The MANGOS shift
The acronym circulating in venture and tech circles—MANGOS, for Meta (or Microsoft), Anthropic, Nvidia, Google, OpenAI, and SpaceX—names the next dominant cohort after FAANG. Half of that list is already public; the other half is about to be. Whether the label sticks matters less than the underlying bet: that AI infrastructure and frontier model companies will anchor portfolios the way social platforms and cloud providers did in the 2010s.
What remains uncertain is whether public investors will tolerate the burn rates and long timelines these companies require. Anthropic and OpenAI both operate at a loss, pouring revenue into compute and research. SpaceX has Starlink cash flow, but Starship development is expensive and open-ended. The IPO window is open now, but the real test comes when growth slows and the market decides whether these companies are the next Nvidia or the next WeWork.
