Claude Mythos 5 access restored by…?

Platform comparison

Market context

On 1 July 2026, the US government lifted export restrictions, allowing Anthropic to restore access to Claude Mythos 5 for a set of US organisations defending critical infrastructure. This real-world shift directly contradicts the current 0% crowd-implied probability on Polymarket, where the contract is priced as if restoration is impossible. The on-chain mechanics—USDC settlement on Polygon using conditional tokens—now face a stark mismatch between market pricing and verified official announcements confirming redeployment is underway [1][3].

Historical precedent from the June 12 suspension shows that when the Commerce Department issued a narrowed directive just weeks later, Anthropic restored Fable 5 for all customers, proving regulatory flexibility is possible [2]. Mythos 5 remains distinct in that it is not generally available but restricted to vetted cyberdefenders under Project Glasswing, yet the same model underpins both products [2][4]. Traders should watch for official rollout confirmations from AWS Bedrock, Google Cloud Vertex AI, and Microsoft Foundry, as these platforms were the first to regain access to Fable 5 and are now expected to mirror Mythos 5 restoration [5].

The primary catalyst is the scheduled provisioning of approved US providers, which Anthropic stated it is executing quickly following government notification [1]. A recent WIRED report confirms over 100 US entities, including major corporations and governmental bodies, are now permitted to regain access, with safeguards deemed sufficient [8]. Traders must monitor Anthropic’s official documentation and AWS blog updates for the exact date when Mythos 5 becomes active for these partners, as this will trigger the market’s resolution to “Yes” before the 30 June 2026 settlement window [5][9].

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 PolyGram, 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.

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 PolyGram 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.
