Anthropic Files Confidential IPO Papers Ahead of OpenAI

*Anthropic’s move gives it an early path to public markets that could translate into faster access to chips and data centers than its main rival.*

Anthropic PBC filed confidential IPO documents on Monday. OpenAI has not made a comparable filing. The step puts Anthropic in position to reach U.S. public markets first in the contest between the two AI companies.

Both firms have raised large sums in private rounds while spending heavily on model development. The filing race is not only about valuation optics. The company that lists first can tap deeper liquidity to fund the hardware and talent required to train larger systems.

The source notes that the first firm to access public capital gains an immediate edge in securing chips, data centers, and staff. Elon Musk’s plans to combine SpaceX AI efforts with a hyperscaler and chip venture add further pressure on both OpenAI and Anthropic to avoid falling behind on funding timelines.

Why it matters

The order of IPOs will shape which lab can sustain the capital demands of frontier model training over the next several years. Public-market access provides a structural advantage that private rounds alone have not delivered.
