Pronóstico: Claude Fable 5 restored for US customers by…?

Platform comparison

Market context

The US government has issued an export control directive forcing Anthropic to suspend all access to its advanced models, Claude Fable 5 and Claude Mythos 5, for foreign nationals regardless of location. Because real-time segmentation of foreign users is impractical across a global customer base, Anthropic abruptly disabled both models for every customer worldwide on 12 June 2026, citing national security authorities as the basis for the order[1][5]. This blanket suspension means the current 0% YES probability on Polymarket reflects the near-certainty that Anthropic will not restore access to these specific models before the July 2026 settlement date, as the directive remains legally binding and unchallenged[2][6].

Historically, similar export control actions by the US government have resulted in permanent restrictions rather than temporary pauses, with no precedent for restoring access to a model once a national security directive has been enacted[4]. Comparable cases involving technology firms facing BIS (Bureau of Industry and Security) mandates show that companies typically comply fully and maintain restrictions indefinitely, often replacing the banned product with a modified version that meets regulatory requirements rather than reinstating the original[2]. The 0% market price aligns with this pattern, suggesting traders view the suspension as a definitive regulatory outcome rather than a negotiable operational hurdle.

Traders should monitor official announcements from Anthropic regarding any potential substitute models or revised compliance frameworks, as well as updates from the BIS on whether the directive scope might be narrowed[4]. Recent reporting by Reuters confirms the US ordered Anthropic to halt foreign access citing national security concerns, with no indication of an imminent reversal[3]. Key dependencies include whether Anthropic releases a new model confirmed to be functionally identical to Fable 5 or Mythos 5 under a different name, which would qualify for a "Yes" resolution if named appropriately, though current signals suggest this is unlikely before the settlement window closes[2][6].
