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

According to the latest prediction market data for the query “Which company has the best Math AI model end of July?”, traders have formed a strong consensus.

Currently, Anthropic is dominating the market with an overwhelming 67.5% chance of winning. Google follows in second place at 23%, while OpenAI sits in third with 8.6%. The betting volume for this specific market has already reached $52.5K, reflecting intense industry interest.

To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• Anthropic (67.5%): Currently commanding the highest probability, Anthropic is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 68¢, signaling a high degree of market conviction. This contract alone has generated $15.2K in volume.

🥈 Tier 2: The Primary Challengers

• Google (23%): Positioned as the most viable alternative, Google maintains a 23% chance of resolving true. Its “Buy Yes” shares currently trade at 23¢.
• OpenAI (8.6%): Sitting in third place with a 8.6% probability, the market shows measured skepticism toward OpenAI, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~0.8%)

Beyond the top three choices, a wide field of macro variables and long-shot outcomes are being tracked. While their individual probabilities hover low, they represent crucial hedges for speculative traders:

• Alternative Options: This includes xAI (0.5%), Alibaba (0.1%), and Z.ai (0.1%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like DeepSeek are still attracting notable interest.

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. 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.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome Anthropic currently trades at 67.5%, but our AI places its Fair Value at just 63.2%. This creates a large negative EV Gap of -4.3%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies Google as the premium value opportunity on the board. While the market only assigns it a 23% trading probability, our AI’s Fair Value assessment sits at 26.4% — yielding an impressive +3.4% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include Z.ai (EV Gap: +1%) and DeepSeek (EV Gap: +1%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
