Recent breakthroughs by OpenAI models have driven strong trader consensus that another FrontierMath Open Problem will be officially solved before year-end. GPT-6 Astra’s mid-September solution of a decade-old social choice theory problem—classified by Epoch AI as the first “Major Breakthrough” level result—followed GPT-5.4 Pro’s earlier verified hypergraph solution and pushed Tier 4 saturation to 97.6 percent. OpenAI’s iterative agent swarms and targeted prompting have outpaced competitors on research-grade benchmarks, while Epoch continues auditing and expanding harder sets such as FrontierMath Erdős. With the market resolving on Epoch’s formal classification through December 31, any additional verified open-problem solution would trigger resolution, though exact timing remains subject to internal validation and researcher collaboration.
