Intro

This market tracks which company owns the AI model ranked first on the Chatbot Arena LLM Leaderboard's Math category. Across Polymarket and Kalshi, the consensus probability for the leading outcome stands at 55.0%, with Google's model at 41.5%. Both platforms reference the Chatbot Arena LLM Leaderboard at https://lmarena.ai/ as the resolution source, checking the Math category rankings with style control off. Watch the leaderboard standings as they stand on June 30, 2026, at 12:00 PM ET, when this market will resolve based on which company's model occupies the #1 rank at that specific checkpoint.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue:

Polymarket and Kalshi both reference the Chatbot Arena Math leaderboard but diverge on resolution timing (12:00 PM ET vs. 10:00 AM ET) and model naming scope. Kalshi's seven model options may not exhaustively cover all possible #1 outcomes, creating potential ambiguity.

Hero Tip:

Prioritize the 10:00 AM ET Kalshi snapshot as the leading indicator. Cross-check that the #1 model at that time matches one of Kalshi's seven listed models (Claude, ChatGPT, Gemini, Qwen, Kimi, Mimo, Minimax). If the #1 model is not in Kalshi's list, expect Kalshi to resolve ambiguously or cancel. Polymarket's later 12:00 PM ET check may diverge if the leaderboard shifts within the 2-hour window.

Critical Divergence Points:

  • Polymarket:

    Resolves at 12:00 PM ET on June 30, 2026. Uses company-to-model mapping (Alibaba, ByteDance, Amazon, Meta, xAI, Baidu, Z.ai, Anthropic, OpenAI, Moonshot, DeepSeek, Microsoft, Google, Mistral, Meituan, plus 15 placeholder companies A-M and 'any other'). Tiebreaker hierarchy: rank, then arena score (granular), then alphabetical company name. Fallback: if leaderboard unavailable, resolves on first check after restoration; if permanently unavailable, alternative source used.
  • Kalshi:

    Resolves at 10:00 AM ET on June 30, 2026. Lists seven specific model names (Claude, ChatGPT, Gemini, Qwen, Kimi, Mimo, Minimax) without explicit company attribution. Each model is a separate Yes/No market. No tiebreaker logic or fallback source specified. If #1 model is not in the seven-model list, resolution path is undefined.
Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Polymarket

This market will resolve according to the company that owns the model that has the highest arena rank based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab for "Math" is checked on June 30, 2026, 12:00 PM ET. Results from the "Rank" column under the "Text Arena | Math" Leaderboard tab at https://arena.ai/leaderboard/text/math-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 first 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.

Kalshi

The top-ranked model on the Arena AI Text Arena Leaderboard (Math) Style Control Off at 10:00AM ET on June 30, 2026 determines the resolution. When models are tied under Rank, the tiebreaker hierarchy is applied in sequence: first, the model with the highest Arena Score; second, the model with the most votes; third, the model that was released earlier. This sequential tiebreaker process ensures a single definitive outcome.

Frequently asked questions

The best Math AI model market aggregates trader predictions across Kalshi and Polymarket to identify which company will lead in mathematical reasoning AI by mid-2026. This market reflects real-time consensus on whether Anthropic, OpenAI, Google, or another competitor will claim the top position. Traders on both platforms price their conviction based on benchmark results, research announcements, and product releases. The cross-platform view reveals how different communities weight the same catalysts, with Kalshi currently showing 1.0% conviction in its leading outcome. Tracking this market provides insight into expert and algorithmic expectations around AI capability leadership during a critical period of rapid model development.

Prediction market odds often diverge from traditional analyst reports because traders incorporate real-time information, leaked benchmarks, and community intelligence that formal research may lag. This market prices in live sentiment from AI researchers, investors, and technologists who trade on proprietary insights or early product signals. Unlike analyst forecasts published quarterly or annually, market odds update continuously as new evidence emerges. Prediction markets also aggregate dispersed knowledge across thousands of participants, sometimes surfacing consensus before mainstream media coverage. However, analyst reports may include deeper technical context or longer-term strategic views that spot markets haven't yet priced in, making both sources complementary for a complete picture.

Kalshi and Polymarket may show different odds on the same outcome due to variations in user base composition, liquidity depth, and settlement rule interpretation. Kalshi and Polymarket can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Each platform attracts traders with distinct risk appetites and information sources, so one may react faster to news than the other. Liquidity imbalances can also widen spreads; if one platform has deeper order books, its price may be more resilient to large trades. Additionally, subtle differences in how each platform defines or verifies the winning company can create pricing gaps. Savvy traders monitor both venues to identify arbitrage opportunities, though transaction costs and withdrawal delays typically prevent perfect convergence.

This market resolves around Jun 30, 2026, at which point the outcome is confirmed based on credible public reporting and benchmark results available at that time. The winning company will be identified through peer-reviewed publications, official model releases, standardized math competition leaderboards, or widely recognized AI evaluation frameworks. Resolution hinges on verifiable evidence of which organization's model demonstrates superior mathematical reasoning capabilities as of the end date. Once the outcome is clear from public sources, the market settles and traders receive payouts proportional to their positions. The exact timing of settlement may vary slightly depending on how quickly definitive information becomes available.

Major catalysts include new model releases from leading AI labs, published benchmark results on standardized math tests, and announcements of research breakthroughs in mathematical reasoning. Academic papers demonstrating novel approaches to symbolic reasoning or theorem proving could shift trader conviction significantly. Hiring announcements, funding rounds, or partnerships that signal capability investments may also move odds. Leaked internal evaluations or early access reports from researchers can trigger rapid repricing. Competitive product launches or public demonstrations at conferences will likely drive volatility. Additionally, regulatory developments or safety concerns affecting specific companies could indirectly influence market sentiment. Traders monitor AI research communities, preprint servers, and industry news closely for any signal suggesting which company is pulling ahead in this critical capability race.
