Next Mythos-Class Model released by…?

Platform comparison

Market context

Anthropic already shipped the last Mythos-class step on 9 June, when Claude Fable 5 was released as the public version of that line and then rolled out across its products and plans in stages.[1][2] That matters because the market is effectively asking for a fresh public-class launch inside a short window, and the company’s recent pattern has been to keep the model available while adjusting access terms, rather than treating launch day as the end of the story.[1][3]

For traders, the key catalysts are any newsroom post, product page update, or access change on Anthropic’s site, plus whether a successor is named as Mythos-class rather than merely another Fable variant.[1][4] Anthropic has already used staged availability, then later restored wider access after export controls lifted on 30 June and the model returned globally on 1 July, which shows how release timing and public accessibility can shift quickly.[3][7] A further signpost is whether Anthropic publishes another official model announcement before the 1 October settlement cut-off; absent that, the current 0% implied probability reflects the lack of a clearly signposted next launch cycle.[12]

UK Frequently Asked Questions

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
