Which company has the best Math AI model end of July?

Platform comparison

Market context

The market bets on which firm will hold the top spot on the Chatbot Arena’s Math leaderboard when checked in late July 2026. Current crowd-implied probability sits at 49% YES, treating Anthropic’s Claude Opus 4.6-Thinking as the favourite, given it currently leads the Text Arena Math category with 1518 Elo, a score that has risen 172 points since tracking began [1].

Historical volatility in the Math arena suggests the consensus may be overconfident; the leaderboard is highly sensitive to minor data shifts, where removing less than 1% of preference data can flip the top rank [8]. While Claude Opus 4.6-Thinking holds the lead now, GPT-5.4 Pro previously surpassed Claude Opus 4.6 by 8 Elo points in March 2026 for general reasoning, demonstrating that OpenAI can rapidly close gaps in mathematical capability [3]. This fluidity creates a value spot for contrarians betting on an OpenAI or Google upset, as the 49% price implies a stable lead that the data history does not support.

Traders must monitor the release schedules for Anthropic’s next Opus iteration and OpenAI’s GPT-5.5, as both firms have shown capacity for sudden Elo jumps in the 1500+ tier [3]. The Math category is one of the fastest-improving, averaging 10.4 Elo points per month, meaning a single major announcement in the final three weeks before settlement could overturn the current hierarchy [1]. Dependence on the specific “Math” tab check at 12:00 PM ET on 31 July 2026 adds a binary timing risk, where a model released hours earlier could dominate the final snapshot [1].

Methodology

We track Which company has the best Math AI model end of July? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Who Will Win 2026 trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
