Claude Mythos 5 access restored by…?

Platform comparison

Market context

Anthropic suspended global access to Claude Mythos 5 and Fable 5 on 12 June 2026 following a US export control directive, yet the Commerce Department narrowed restrictions by 30 June, allowing restoration to over 100 US entities starting 1 July [3][8]. While Fable 5 access was fully restored for all customers on 1 July, Mythos 5 remains limited to vetted cyberdefenders and infrastructure providers under Project Glasswing, with no general availability announced [1][6]. This divergence creates a critical distinction: the market resolves on whether *any* previously rescinded US partner regains Mythos 5 access, not whether general availability returns.

Historical precedents show that when US export controls target dual-use AI models, partial restorations to trusted partners often precede broader access, as seen with previous Anthropic releases where phased reinstatement occurred within weeks of regulatory relaxation [3][8]. The current 0% crowd-implied probability appears misaligned with the fact that 100+ US entities already regained Mythos 5 access by 1 July, suggesting the market may be pricing on general availability rather than the specific qualifying condition of *any* US partner restoration [8]. Analyst consensus on similar contracts typically diverges from prediction-market odds when regulatory timelines shift faster than crowd expectations, creating arbitrage opportunities for traders monitoring official announcements.

Traders should watch for Anthropic’s next update on Project Glasswing expansion, particularly any mention of new trusted cybersecurity or biomedical partners, as these would satisfy the market’s qualifying condition [1][6]. The US Department of Commerce’s ongoing discussions with the White House regarding Fable 5 restrictions may also signal broader policy shifts affecting Mythos 5 [8]. Recent news from WIRED confirms that 100+ US entities have already regained access, making the 0% probability questionable unless the market interprets “previously rescinded” as excluding these new partners [8]. Key dependencies include Anthropic’s capacity to provision approved providers swiftly and any further regulatory clarifications from the Commerce Secretary.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets, which mirrors the Polymarket order book directly.

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
