Resolution criteria on PolyGram: 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 July 31, 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.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

The Chatbot Arena's mathematics leaderboard will determine which company operates the highest-ranked model on 31 July 2026. The resolution mechanism uses the "Text Arena | Math" rankings from lmarena.ai, with models ordered by their position in the leaderboard's Rank column at the specified settlement time. Current order book pricing implies a 52% probability for the affirmative outcome, suggesting meaningful uncertainty about whether a single company will maintain clear dominance in mathematical reasoning capabilities across the evaluation period.
Historical precedent from large language model benchmarking shows that leaderboard leadership in specialised domains shifts based on model release cycles and architectural improvements. OpenAI, Anthropic, Google DeepMind, and Meta have each held top positions across different mathematical reasoning benchmarks over the past eighteen months. The Chatbot Arena's mathematics track specifically emphasises problem-solving over general conversation, which can favour models with particular training approaches. Previous mathematics-focused evaluations have shown that ranking volatility increases when new model versions release, particularly when organisations prioritise mathematical capability as a competitive differentiator.
Traders should monitor major model announcements through Q3 and Q4 2025, as release timing directly affects July 2026 leaderboard composition. Anthropic's Claude updates, OpenAI's o-series development trajectory, and Google's Gemini iterations represent key catalysts. The leaderboard's voting mechanism means that user preference patterns matter as much as raw benchmark performance, introducing an element dependent on which models receive heaviest Arena usage during the evaluation window. Any significant architectural breakthrough in mathematical reasoning or chain-of-thought capabilities announced before mid-2026 could reshape competitive positioning.
The White Company was a European free company active during the 14th century. Initially known as the Great Company of English and Germans, it was later commonly referred to as the English Company. The company arrived in Italy in 1361, led first by the German mercenary Albert Sterz and later by the Englishman John Hawkwood, under whom it gained its greatest n
The White Company is a historical adventure novel by British writer Arthur Conan Doyle, set during the Hundred Years' War. The story is set in England, France and Spain, in the years 1366 and 1367, against the background of the campaign of Edward the Black Prince, to restore Peter of Castile to the throne of the Kingdom of Castile.

Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "Which company has the best Math AI model end of July?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$517 in lifetime turnover and $3K of resting liquidity puts this market in the below the median by volume for tech contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $517 in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a 2-hour dispute window opens, and if uncontested the payout is final. Contested outcomes escalate to UMA token holders.
This prediction market is scheduled to close on 31 July 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.
To trade on this prediction market, create a free PolyGram account at polygram.ink, deposit USDC via Polygon, and place a YES or NO order on the outcome you believe in. You can learn more on our how-it-works page. Your maximum loss is limited to your stake — there is no leverage or margin.
When the outcome is determined, winning YES shares pay out $1.00 each in USDC, while losing shares pay $0.

You can withdraw your winnings to any Polygon wallet.
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
