Anthropic and OpenAI have confidentially filed for initial public offerings in the United States to enter the public stock market [1, 2].
These filings signal a pivotal shift for the artificial intelligence sector as its most prominent private firms seek massive infusions of public capital. The move comes as the industry faces increasing pressure to monetize generative AI technologies while managing the immense costs of computing infrastructure.
Anthropic filed its confidential application on June 1, 2026 [1]. Some reports indicate the company could launch its IPO as early as July 2026 [4]. The firm has reportedly engaged in a charm offensive with investors to shore up confidence ahead of the listing [3].
Market estimates place Anthropic's valuation at $965 billion [5]. This figure suggests a public debut that could rival the scale of other massive private entities like SpaceX [5].
OpenAI also filed for a U.S. IPO in early June 2026 [2]. However, the timing of OpenAI's transition to a public company remains a point of contention among analysts. While some reports confirm the recent filing [2], other reports suggest the company has deferred its plans until next year [4].
Both companies are pursuing these listings to capitalize on the booming AI sector [3]. By going public, the firms can provide liquidity to early employees, and investors, while raising the funds necessary to maintain their competitive edge in model development. The race to list reflects the broader volatility of the tech market—where the window for a successful blockbuster IPO can close quickly if investor sentiment shifts.

The simultaneous push toward public markets by Anthropic and OpenAI suggests that the AI industry is moving from a research-heavy phase into a commercial scaling phase. If both firms successfully list, it will provide a public benchmark for AI valuations, potentially triggering a wave of IPOs from smaller AI startups. However, the contradiction regarding OpenAI's timeline indicates that internal governance or regulatory hurdles may still be influencing the pace of their transition.
