Market context
Polymarket currently prices Claude 5's public release before year-end 2025 at zero, with USDC liquidity thin and conditional tokens trading near worthless on Polygon. This reflects the market's assessment that Anthropic will not launch a product explicitly branded Claude 5 with general public access—including open beta or rolling waitlist—within the next eleven months. The settlement criteria are strict: closed beta, private access, or enterprise-only availability would all resolve this contract to No.
Anthropic's release cadence provides the primary historical frame. Claude 3 arrived in March 2024 across three capability tiers (Haiku, Sonnet, Opus), with public availability immediate. Claude 3.5 Sonnet followed in June 2024, also publicly released without extended gatekeeping. The company has shown willingness to ship major model revisions on roughly six-month intervals, though no explicit roadmap commits to a Claude 5 label or timeline. Competitors' naming conventions—OpenAI's GPT-4 to GPT-4o progression, Meta's Llama versioning—suggest major numbered releases remain infrequent, typically spanning 12–18 months between generations.
Traders should monitor Anthropic's official announcements, earnings calls from parent investors, and developer conference schedules through Q4 2025. The company has not publicly signalled a Claude 5 development programme or target launch window. Any credible statement from leadership regarding a numbered major release, capability roadmap, or public availability timeline would move this contract sharply. Current zero pricing reflects genuine uncertainty about whether Anthropic will even use the Claude 5 designation, rather than incremental versioning like Claude 3.6 or product-line differentiation.
Methodology
We track Claude 5 released by…? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
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.
