The main risk lies in the definition of 'Claude Mythos'. If Anthropic releases the model under a different name (e.g., Opus 5.0) without confirming it is the leaked model from March 26, it resolves to 'No' even if the US government gets access. Additionally, general public availability is insufficient; there must be explicit authorization or an announcement specifically regarding US federal government access.

The market is currently pricing a 38% chance for April 30 and 45% for June 30, which diverges significantly from mainstream media sentiment. Major outlets like Bloomberg and Politico report that the White House is already drafting internal guardrails for agencies to use Mythos, and high-level meetings have just occurred, suggesting an imminent agreement. The prediction market may be overestimating the political friction caused by the Pentagon's blacklist while underestimating the speed at which civilian agencies are pushing for access.
