🏢 SpaceX, OpenAI, and Anthropic: the triple IPO that will shake up 2026

SpaceX just registered its IPO with the SEC at a $1.75 trillion valuation. OpenAI is preparing its own for September, valued between $852 billion and $1 trillion. Anthropic wants to go public in October. Together, these three companies could raise more capital than all US IPOs combined since 2022. And meanwhile, Google I/O left 100 announcements and Grok failed where it hurts most: the government of its own country. This isn't a bubble — it's a reconfiguration of global capital.

🏢 SpaceX, OpenAI, and Anthropic: the triple IPO that's going to blow up 2026

This is historic. SpaceX filed its S-1 on May 20 and aims to list in June under the ticker SPCX at a $1.75 trillion valuation. OpenAI is filing its confidential S-1 with the SEC today, targeting September at a valuation between $852 billion and $1 trillion. Anthropic, which just closed its Series H and reached $965B, is aiming for October.

Together, these three IPOs could raise more capital than all US IPOs combined since 2022. Polymarket data gives an 85% probability that OpenAI lists before Anthropic, but the prediction market is divided. What nobody disputes: 2026 is the year of mega-AI IPOs.

From IPOs to failure: while the big players prepare to list, others show that money can't buy everything.

Grok fails where it hurts

While Google, OpenAI, and Anthropic grab headlines, xAI — Musk's company — has failed spectacularly in its attempt to secure a contract with the US government. Grok, its flagship model, didn't pass the security filters required for government use. The irony isn't lost on anyone: the company that makes the most noise about "safety" and "transparency" can't sell to its own government.

The contrast with the week is brutal. While Anthropic sues the Pentagon for refusing to build autonomous weapons and gains credibility, xAI can't even pass a basic security check. It's not all money — reputation and ethics are assets too.

Record valuations, public failures, and a race against time. The IPOs of 2026 aren't just financial — they're the final exam of which companies go from promises to institutions. And investors, governments, and clients are already taking notes.
