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 Chatbot Arena rank for mathematics by late July 2026, with current odds implying a 50% chance for the YES outcome. At present, Anthropic’s claude-opus-4-6-thinking leads the Math Arena with an Elo of 1518, outpacing rivals by a margin that has narrowed significantly since early 2026 [1]. Historical data shows Math Elo has surged +172 points since tracking began, making it one of the fastest-improving categories where leaderboard volatility remains high [1]. Comparable cases from 2024–2025 reveal that top Math ranks often flip within weeks following major model releases, suggesting the current 50% implied probability reflects genuine uncertainty rather than a clear favourite.

Traders should monitor Anthropic’s release schedule for Opus 4.7 or a dedicated “Math” variant, alongside OpenAI’s planned GPT-5.5 launch, which could disrupt the current hierarchy [3]. A recent analysis notes that Chatbot Arena rankings are highly sensitive to small data shifts, with dropping just two preferences altering conclusions [8]. This fragility means a single high-profile benchmark update or arena reweighting could swing the outcome. Key catalysts include July 2026 model announcements from Anthropic, OpenAI, and Google, as well as any changes to the Arena’s Math-specific evaluation protocol. The settlement relies on the “Text Arena | Math” tab at 12:00 PM ET on 31 July 2026, so timing of final releases is critical.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
