The recent OpenAI-led resolution of Navier-Stokes using thousands of AI agents has sharpened focus on remaining Millennium Prize Problems, yet market-implied odds place “no solution by December 31, 2027” narrowly ahead at 35 percent. Hodge Conjecture and Birch and Swinnerton-Dyer follow closely at 26 percent and 22.5 percent because targeted multi-agent workflows at OpenAI and Anthropic have generated verifiable partial progress on algebraic geometry and elliptic-curve L-functions, while Riemann Hypothesis, P versus NP, and Yang-Mills lag on thinner reported traction. Traders weigh rapid benchmark gains against the need for Lean-formalized proofs and independent scrutiny, which historically extend timelines. Key swing factors include upcoming internal-model releases, FrontierMath saturation levels, and any new collaborative human-AI attacks before year-end 2027.
