xAI’s Grok models have posted steady gains on the demanding Humanity’s Last Exam benchmark, with Grok 4.5 recently reaching 40.3% accuracy amid a field where leading entries from Anthropic and OpenAI now exceed 50%. Competitive pressure from frequent frontier releases by Google, Meta, and others continues to shape outcomes, while xAI’s focus on scaling reasoning capabilities and tool use drives incremental improvements. Traders watch for any 2026 model updates or new capability demonstrations that could shift relative rankings before year-end resolution.

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.
