This market asks whether xAI will be the company behind the No. 2 model on the Coding leaderboard at Chatbot Arena at the June 30, 2026 check. It is a narrow question about ranking rather than general model quality, so the exact leaderboard snapshot and tie-breaking rules matter a lot. Because the leaderboard can change as new coding models are added or re-ranked, the outcome may stay uncertain until the final check time.
The market resolves by looking at the "Text Arena | Coding" leaderboard on lmarena.ai, with style control off, at June 30, 2026, 12:00 PM ET. The relevant outcome is not whether xAI has a strong coding model, but whether the company owning the model in second place on that leaderboard is xAI at that moment. If two models tie, the rules first use Arena score, including unrounded granular values, and then break any remaining tie alphabetically by company name.
xAI is a prominent AI company, and coding benchmarks are one of the main public ways people compare model quality. This market focuses on a very specific cutoff—second place on one leaderboard—so small changes in rank, scoring, or tie handling can flip the result even if xAI remains near the top. Readers are essentially watching whether xAI can stay ahead of rivals in a public coding comparison at the end of June 2026.
The biggest price movers are changes to the Coding leaderboard itself: a new model launch, a model update, or a re-rank that pushes xAI into or out of second place. Because the rules use the live leaderboard at a fixed check time, even a short-lived shift near the deadline could matter if it is still present at noon ET on June 30. Any changes in Arena scoring, leaderboard formatting, or a tie resolved by exact underlying scores could also affect which company is counted as second.

View marketThe current market price implies roughly a 1% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.
Before resolution, readers should verify the current Coding tab on the Chatbot Arena leaderboard, the exact model name listed in second place, and the company associated with that model. The market uses the leaderboard rank first, then exact Arena score, then alphabetical company order if needed, so a close tie is especially important to watch. If the leaderboard is unavailable at the scheduled check time, the rules say the market stays open until it comes back online and resolves on the first later check, so the source’s availability is part of the outcome path as well.

This market is currently listed with an end date of Jun 30, 2026. Market timelines can change if the underlying event is postponed, rescheduled, or resolved early.
This market will resolve according to the company that owns the model that has the second-highest arena rank based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab for "Coding" is checked on June 30, 2026, 12:00 PM ET. Results from the "Rank" column under the "Text Arena | Coding" Leaderboard tab at https://arena.ai/leaderboard/text/coding-no-style-control with style control off will be used to resolve this market. Models will be ordered primarily by their leaderboard rank at the market’s check time. If two or more models are tied on rank, they will be ordered by their Arena score, including any underlying, unrounded, granular values reflected in the data below the leaderboard. If a tie still remains, alphabetical order of company names as listed in this market group will be used as a final tiebreaker (e.g., if the two models are tied by exact arena score, “Google” would be ranked ahead of “xAI”). This market will resolve based on the company that occupies second place under this ranking. 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 will resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve based on another resolution source.
