The race for AI supremacy is playing out vividly on prediction markets. Anthropic's Claude is now trading at 92¢ (0xa4d72632ac0ddadcac) to be the best AI model at end of June, a 2¢ increase on the day with nearly 70,000 in volume. This dominance is remarkable — Google trails at 7¢ (0x0bd1b836a2494f80aa), OpenAI at just 2¢ (0x734c6c32a62f8a2703), and xAI at effectively 0¢. The market is pricing in a clear winner.

However, the GPT-5.6 release timeline is showing life: the 'released by June 15' contract (0x1ff94ce9a874202523) jumped 7¢ to 24¢, while 'by June 30' (0xe69b388ee2691abc5a) trades at 94¢ — meaning the market is near-certain we'll see it by month-end. The release window is concentrated in the June 15-21 period at 49¢ (0xee786ee609e3a767df).

Key contracts to watch: - **Best AI model end of June: Google** (0x0bd1b836a2494f80aa): 7¢, -1¢ — losing ground to Anthropic - **Second best AI model: Anthropic** (0xd0e97d28b706d26f47): 86¢ — the secondary market confirms the pecking order - **Mythos release before July 1** (KXCLAUDE-MYTH-26JUL0): 2¢, but the 'before Jan 1 2027' contract (KXCLAUDE-MYTH-27JAN0) is at 27¢ — a longer timeline - **Top AI model in June: Anthropic** (KXLLM1-26JUN13-ANTH): 99¢ — essentially certain

The narrative is clear: Anthropic's Claude has seized the AI crown from OpenAI, at least for now. The GPT-5.6 release could reset expectations. Traders should watch the 'best coding AI' markets (KXCODEAI-26JUN30-CHA at 54¢ for Claude) for validation. If OpenAI releases something transformative, expect violent repricing.
