Claude 5 released by…?

Market context

Anthropic must release Claude 5 as a publicly accessible product—via open beta, rolling waitlist, or general availability—before the end of 2025 for this market to settle Yes. Closed beta access, enterprise-only tiers, or announcement-only does not qualify. The current 0% implied probability reflects market scepticism that a major new model iteration will reach public hands within roughly 12 months from the market's creation.

Anthropic's release cadence offers the primary historical anchor. Claude 3 (Opus, Sonnet, Haiku variants) launched in March 2024 and reached public availability through Claude.ai and API within weeks. Claude 3.5 Sonnet arrived in June 2024, also with immediate public access. The gap between major numbered releases—from Claude 2 (July 2023) to Claude 3 (March 2024)—was nine months. A Claude 5 release by end-2025 would require Anthropic to compress its typical development cycle or have begun work substantially earlier than public signals suggest. Comparable timelines at OpenAI (GPT-4 to GPT-4o: ten months) and Google DeepMind (Gemini 1.0 to 2.0: six months) show variation, but none demonstrate a pattern of sub-annual major releases becoming standard.

Traders should monitor Anthropic's official announcements, earnings calls or funding disclosures, and research publication schedules. CEO Dario Amodei's recent statements (as of late 2024) have emphasised scaling and safety work rather than imminent product launches. Any public roadmap, hiring announcements for deployment teams, or infrastructure expansion would signal acceleration. Polymarket's zero probability aligns with Kalshi and Betfair's typical pricing on compressed timelines; Smarkets' decimal odds format would reflect similar scepticism, though KYC requirements vary across platforms and may affect liquidity depth on longer-dated AI markets.

Methodology

This page compares Claude 5 released by…? specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. Live odds come from the Polymarket order book; the other venues' contract details are maintained manually because their APIs aren't directly comparable. Every CTA routes to Polymarket Alternative, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
