Claude 5 released by…?

Market context

Anthropic's release of a Claude 5 model to the general public by year-end 2025 currently trades at zero implied probability across prediction markets, despite the company's established pattern of moving from closed testing to public availability within 6–12 months of initial announcements. The zero reading reflects genuine uncertainty about whether Anthropic will brand its next major release as "Claude 5" rather than continuing incremental versioning (Claude 3.5 Sonnet, for instance), or whether any such release will meet the market's strict definition of general public access—excluding closed betas and waitlists.

Anthropic's historical release cadence offers limited precedent. Claude 3 family models launched in March 2024 with immediate public availability across multiple platforms; Claude 3.5 Sonnet arrived in June 2024 following the same pattern. However, neither represented a major version increment. The company has not yet released a model explicitly branded as a numbered major version beyond Claude 3, making the timing and nomenclature of a "Claude 5" release genuinely ambiguous. Competitors including OpenAI and Google have also shown willingness to skip major version numbers or use alternative naming schemes, reducing confidence in any specific timeline.

Traders should monitor Anthropic's quarterly announcements and earnings calls for explicit references to Claude 5 development timelines. Recent reporting from The Information (September 2024) indicated Anthropic was training larger models but offered no public commitment to a 2025 release date. The settlement window extends to April 2026, creating asymmetric risk: a December 2025 release would need public announcement and rollout within a compressed window, whilst the zero probability suggests markets view this outcome as unlikely rather than impossible.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
