Anthropic IPO by 2027?

Market context

Anthropic, the AI safety company founded in 2021 by former members of OpenAI, would need to file for public listing and complete regulatory approval to trade on a major securities exchange by 1 July 2027. The company has raised over $7 billion in private funding rounds, most recently a $5 billion commitment from Amazon announced in September 2024, valuing it at approximately $60 billion. No formal IPO filing has been submitted to the SEC, and the company has made no public statements indicating imminent plans for a public listing.

The 1% implied probability reflects the substantial distance between current private status and public markets. Comparable AI-focused companies have taken varied paths: OpenAI remains private despite its market prominence, whilst others like C3 Metrics and Scale AI have extended their private fundraising cycles well beyond initial expectations. The typical timeline from S-1 filing to trading debut spans 4–6 months, meaning any IPO by mid-2027 would require filing by early 2027 at the latest. Anthropic's recent funding rounds and strategic partnerships with major cloud providers suggest the company may prioritise growth and product development over near-term public markets access.

Traders should monitor announcements regarding Anthropic's financial performance, regulatory filings with the SEC, and any acquisition proposals—the market explicitly resolves to "No" if the company is acquired by an already-public entity. Changes in leadership, shifts in funding strategy, or explicit statements from company executives about public market timing would materially alter the probability. The settlement window's 2027 endpoint provides roughly 2.5 years for conditions to shift, though current trajectory suggests private status remains the base case.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
