Will xAI have the top AI model at the end of June 2026?

xAI's 5¢ price reflects an extremely low 5% implied probability of topping the Chatbot Arena leaderboard by June 2026, yet the Yes side offers an extraordinary 9375% implied yield—a massive risk-reward asymmetry suggesting either deep skepticism about xAI's competitive positioning or potential underpricing given Grok's rapid development trajectory. The market has declined from 7¢ to 5¢ over seven days with extreme 1365% realized volatility, indicating significant uncertainty and potential information arrival, though the modest $197.6k daily volume and $17k open interest suggest thin liquidity that could amplify price swings. With a Cliff Risk Index of 19 and 74 days to resolution, this appears to be a speculative contrarian bet on xAI's model development pace relative to established competitors like OpenAI and Anthropic.

Resolution rules

This market will resolve according to the company that owns the model with the highest arena score based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked on June 30, 2026, 12:00 PM ET. Results from the "Arena Score" section on the Leaderboard tab of https://lmarena.ai/leaderboard/text set to default (style control on) will be used to resolve this market. If two models are tied for the best arena score at this market's check time, resolution will be based on whichever company's name, as it is described in this market group, comes first in alphabetical order (e.g., if both were tied, "Google" would resolve to "Yes", and "xAI" would resolve to "No") The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://lmarena.ai/. If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and resolves based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve based on another resolution source.
