Anthropic confidentially filed an IPO prospectus on June 1, 2026, aiming to go public before OpenAI and targeting a trillion‑dollar valuation.

Anthropic submitted a confidential IPO prospectus to the SEC on June 1, 2026, positioning itself to list before rival OpenAI, which is also preparing a filing. The move follows Anthropic’s recent $65 billion funding round that lifted its post‑money valuation to $965 billion, overtaking OpenAI’s $852 billion valuation reported in March [4].

The confidential filing lets Anthropic keep key financial details hidden while it readies a roadshow; the prospectus must reach investors at least 15 days before any public marketing begins, a timeline similar to SpaceX’s recent filing [2]. By filing now, Anthropic hopes to capture investor appetite for AI‑driven growth, especially after its revenue run rate surged to $47 billion this year, up from $10 billion a year earlier [2][3]. The company’s rapid expansion has been fueled by deals such as a $1.25 billion‑per‑month compute agreement with SpaceX, which runs through May 2029 [2].

Analysts see the race to market as a strategic battle for fresh capital. Both Anthropic and OpenAI are expected to seek tens of billions in new funding, and the first mover may enjoy a pricing advantage, echoing past tech IPOs where the early entrant outperformed its follower [1]. The SEC’s confidential review process adds uncertainty, but the filing signals Anthropic’s confidence that market conditions will support a high‑profile debut, especially as the broader AI sector continues to attract massive bond‑market financing for data‑center builds [1].

If Anthropic’s IPO proceeds before OpenAI’s, it could set the benchmark for AI valuations and influence how investors allocate capital across the emerging AI giants. The open question remains whether investor demand will sustain the lofty valuations amid intensifying competition and regulatory scrutiny.
