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

Platform comparison

Market context

Anthropic’s Claude Opus 4‑6‑Thinking currently holds the top spot in the Chatbot Arena’s Math leaderboard with an Elo of 1518, giving its owner a clear edge as the market prices in a 49% chance for the “best” outcome by July 2026 [2]. This probability mirrors historical volatility in specialised arenas: in coding and general reasoning, the leader has shifted multiple times within a single year as new models from OpenAI, Google and Anthropic were released, often overturning months of dominance [2][3]. The 49% figure reflects a tight contest where a single high‑profile release could flip the ranking, rather than a stable lead.

Traders should watch the release schedules for GPT‑5.5, Claude 4.7 and Gemini 3.1, all of which have already redefined the hierarchy in broader benchmarks and could displace the current Math leader if their math‑specific variants are strong [3]. Anthropic’s recent announcement that Claude Fable 5 leads a composite quality index across 362+ models suggests continued investment in frontier reasoning, but the Math arena remains sensitive to targeted optimisations [1]. Key catalysts include any Q3 2026 model drops from OpenAI or Google, plus updates to the Chatbot Arena’s Math tab methodology, which could alter rankings even without new models [4][9].

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

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.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Today 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.
