Claude Mythos 5 access restored by…?

Platform comparison

Market context

The US Department of Commerce lifted export controls on 30 June, prompting Anthropic to announce immediate restoration of access to Claude Mythos 5 and Fable 5 starting 1 July. This reversal follows a 12 June directive that abruptly suspended all access, but the government subsequently determined that appropriate safeguards now permit redeployment to trusted US organisations.

Historical precedents for regulatory suspensions in cybersecurity tech show that partial restorations often precede full access, yet current market pricing at 0% implies traders doubt any US partner previously barred will regain access by the settlement date. Similar cases, such as the 2023 temporary ban on advanced chip exports, saw phased reinstatement over months rather than days, suggesting the 11:59 PM ET deadline may be too tight for universal restoration despite the lifted controls[1][2].

Traders should monitor Anthropic’s platform documentation and cloud marketplace flags on AWS Bedrock and Google Cloud for updated availability indicators, as regional turn-ups may lag behind the initial announcement[1]. A critical catalyst is the official cadence of tenant-specific restoration, which Anthropic has not specified; meanwhile, interim fallbacks like Opus 4.8 remain unaffected and reliable[1]. Recent confirmation from Anthropic on X states restoration is proceeding quickly for the 100 approved organisations, but broader access remains under negotiation[2][4].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

Do I need to KYC for this market?

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.
