Claude Mythos 5 access restored by…?

Platform comparison

Market context

The US government has lifted export controls on Anthropic’s Claude Fable 5 and Mythos 5, allowing the firm to restore access to both models. On 12 June 2026, the Trump administration issued a directive that forced Anthropic to suspend access worldwide; by 2 July 2026, the Commerce Department issued a narrowed directive, and Anthropic began restoring access for US organisations operating critical infrastructure [2][3][5].

Historically, similar US export-control suspensions on advanced tech have been reversed within weeks once diplomatic or regulatory negotiations conclude. The Fable 5 case mirrors this pattern: access was reinstated globally on 1 July 2026, roughly three weeks after the initial suspension, with Mythos 5 restored for a limited set of US entities [1][4]. This precedent frames the current 0% crowd-implied probability as overly cautious, given the government’s explicit lift of restrictions.

Traders should monitor Anthropic’s official X updates and the Department of Commerce’s next regulatory notices for expansion of Mythos 5 access beyond critical-infrastructure firms [3][6]. A key catalyst is the 7 July 2026 deadline for Fable 5’s limited-time promotion; any delay in extending general access could signal further friction. Recent reporting confirms restoration is underway, with paid subscribers already able to use Fable 5 tokens under the promotion [2]. On-chain, Polymarket prices this contract using USDC on Polygon, with conditional tokens reflecting the binary outcome tied to the 30 June 2026 settlement window.
