This market will resolve to "Yes" if any SpaceXAI Grok model achieves at least the specified accuracy on Humanity’s Last Exam by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". For resolution, “accuracy” refers solely to the value labeled “HLE Accuracy” or a clear equivalent metric if the data’s presentation or terminology is restructured, regardless of the model’s Calibration Error or any other displayed metric. The resolution source will be the official Humanity’s Last Exam leaderboard at https://agi.safe.ai/. If the resolution source becomes unavailable during the listed timeframe, this market will remain open to allow the relevant data to become available again. If the source remains unavailable after the end of the listed timeframe or is otherwise confirmed to be permanently unavailable, official Humanity’s Last Exam results published elsewhere may be used. If no official alternative source is available, this market will resolve to "No".xAI's recent Grok 4.6 release has driven incremental gains on frontier benchmarks through enhanced reasoning, agentic capabilities, and tool integration, yet the model trails leaders like Claude Opus 5 (64.7%) on Humanity’s Last Exam, with Grok variants recently reported around 40-43%. Trader consensus reflects xAI's steady progress via post-training refinements and cost-efficient scaling, but also the benchmark's resistance to saturation amid rapid releases from Anthropic, OpenAI, and Meta. Key catalysts ahead include potential Grok 4.7 iterations and year-end optimization windows before the December 31, 2026 resolution, where further advances in multi-step expert reasoning could shift outcomes.
