What's at stake

Listing order will determine which company sets the public benchmark for advanced AI valuation.

The first IPO changes investor access, the flow of capital into competing research paths, recruitment leverage, and the public narrative about how profitable and safe cutting‑edge AI companies can be.

Who's in play

Anthropic and OpenAI are the two companies whose filing timetables decide the outcome.

Founders, CEOs, venture investors, underwriting banks, and major customers also influence which firm can and will go public first through capital needs and strategic preferences.

What drives it

Regulators, disclosure requirements, and market appetite shape feasible IPO windows.

Primary drivers include confidential SEC submissions, the willingness of anchor investors, private valuation expectations, lock‑up arrangements, and macro volatility that can make underwriters speed up or delay a float.

What to watch

Watch for S‑1 filings, confidential submissions to the SEC, and formal engagement with lead underwriters.

Also track big secondary funding rounds, public statements from CEOs and board members, major customer agreements, and macro windows like low market volatility or strong IPO comparables.
