Recent AI breakthroughs on frontier mathematics have driven strong trader consensus that Epoch AI will soon classify another Open Problems entry as solved. OpenAI’s September 8 announcement of an internal multi-agent system solving the Navier-Stokes Millennium Problem, combined with Anthropic’s late-August percolation theory proof and Google DeepMind’s early-October Gemini agents resolving multiple Erdős problems and conjectures, reflect rapid capability gains across labs. These verified or formally checked results build on earlier 2026 milestones like GPT-5.4 Pro’s March solution and align with Epoch AI’s independent evaluation process. With ongoing model releases, Lean formalizations, and benchmark updates expected through year-end, markets price near-certain odds of at least one additional classification by December 31.
