Claude Mythos 5 access restored by…?

Platform comparison

Market context

On 12 June 2026, Anthropic suspended global access to its cybersecurity model Claude Mythos 5 following a US government directive prohibiting non‑US nationals from using the tool. By late June, the Department of Commerce lifted restrictions on both Mythos 5 and Fable 5, and on 1 July Anthropic confirmed Fable access had been restored; Mythos 5 is now being redeployed to a small set of US organisations that operate critical infrastructure[1][2].

Historical precedents show that when export controls are reversed, model access typically returns within days to weeks, as seen with prior cybersecurity tools and the swift reinstatement of Fable 5[3]. The current 0% crowd‑implied probability on the prediction market diverges sharply from sportsbook lines on similar regulatory‑reversal contracts and from analyst consensus, which expects Mythos 5 access to be fully restored before the 30 June 2026 settlement deadline[8].

Traders should monitor official Anthropic announcements on X.com, updates from the US Department of Commerce, and any scheduled capacity expansions for Project Glasswing partners[1]. A recent Reddit discussion notes Anthropic’s confidence that access will be re‑enabled within days, reinforcing the likelihood of a “Yes” outcome[8]. The key dependency is whether Anthropic extends redeployment beyond the initial critical‑infrastructure set to at least one previously rescinded US partner before the deadline.

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 UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

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 UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
