Anthropic AI Release Timeline Accelerates: Claude 5 and Mythos Contracts Surge

The AI arms race is heating up, and prediction markets are pointing towards an imminent major release from Anthropic. The contract for 'Claude 5 released by June 30, 2026' (0x562d8e6be61af9176d) surged 34¢ to 71¢, while the September 30 contract (0x8ccd3fe9eccb2448cc) jumped 22¢ to 90¢. Even more striking, the 'Claude Mythos released by June 30' contract (0xcfd48c874ae1760c1e) rose 21¢ to 77¢. These are extraordinary moves for a single day, suggesting either a leak, an official announcement, or a strong signal from the market that Anthropic is about to ship its next flagship models.

This has direct implications for the 'which company has best AI model end of June' market, where Anthropic is already the heavy favorite at 86¢ (0xa4d72632ac0ddadcac). The probability that OpenAI will maintain the lead is dropping, with its contract at just 5¢ (0x734c6c32a62f8a2703). The broader AI sector is also affected: NVIDIA's position as the largest company by market cap at end of June is at 91¢ (0x79afea6a94f0b3dffb), but a strong Anthropic release could shift the landscape.

For traders, these contracts offer a way to bet on the AI race's outcome. The sudden, coordinated move in multiple Anthropic-related contracts is a strong signal that the competitive dynamics in AI are about to shift. The key to watch is whether this is a false start or the beginning of a sustained run-up in probability. The 'Claude score on Humanity’s Last Exam by June 30' contract (0x4a3ae5bc03b849fa2a) at 41¢ (up 17¢) is another indicator of Anthropic's perceived progress. This entire complex of contracts is a direct play on the most important technology theme of the year.
