Market context

Anthropic has not yet publicly announced a model called Claude Mythos or indicated plans to release one under that designation. The company's current product line comprises Claude Haiku, Sonnet, and Opus variants, with version numbering and capability tiers evolving incrementally. A 0% crowd-implied probability reflects the absence of any official roadmap or naming convention suggesting a "Mythos" release before the June 2026 settlement window closes.

Comparable naming schemes in the large language model sector offer limited precedent. OpenAI's GPT line has used numerical designations rather than mythological nomenclature; Meta's Llama models adopted animal naming; Mistral and others have experimented with thematic branding. Anthropic's established taxonomy—drawing from typography and font sizing metaphors—has remained consistent across product announcements since Claude's 2023 launch. Any shift to "Mythos" branding would represent a deliberate departure from this pattern, which historically occurs only when companies signal major architectural changes or capability jumps through press releases or earnings calls.

Traders monitoring this market should track Anthropic's official announcements, including blog posts, API documentation updates, and statements from leadership at industry conferences. Recent funding rounds and partnership news (such as the Google investment announced in 2023) occasionally precede product roadmap disclosures, though Anthropic has been cautious about pre-announcing unreleased models. The June 2026 deadline allows roughly eighteen months for such an announcement to materialise. Polymarket's current odds structure and Kalshi's regulatory framework both treat this as a binary event; traders should note that settlement hinges on Anthropic's explicit use of the "Mythos" designation rather than inference from capability levels.

Methodology

This page compares Claude Mythos released on…? 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

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). Polymarket Alternative routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
