Will any AI model reach ___ Overall Arena Score by December 31?

According to the latest prediction market data for the query “Will any AI model reach ___ Overall Arena Score by December 31?”, traders have formed a strong consensus.

Currently, ↑ 1520 is dominating the market with an overwhelming 63.5% chance of winning. ↑ 1530 follows in second place at 26.5%, while ↑ 1540 sits in third with 14.5%. The betting volume for this specific market has already reached $141.3K, 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

• ↑ 1520 (63.5%): Currently commanding the highest probability, ↑ 1520 is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 64¢, signaling a high degree of market conviction. This contract alone has generated $7.2K in volume.

🥈 Tier 2: The Primary Challengers

• ↑ 1530 (26.5%): Positioned as the most viable alternative, ↑ 1530 maintains a 26.5% chance of resolving true. Its “Buy Yes” shares currently trade at 27¢.
• ↑ 1540 (14.5%): Sitting in third place with a 14.5% probability, the market shows measured skepticism toward ↑ 1540, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~0%)

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 ↑ 1550 (12.5%), ↑ 1600 (10%), and ↑ 1650 (7.5%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like ↑ 1700 are still attracting notable interest.

This market will resolve to "Yes" if any model on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) reaches at least the specified Arena Score by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No".

Results from the 'Score' section on the 'Text Arena' Leaderboard tab (https://lmarena.ai/leaderboard/text), with the style control unchecked, will be used to resolve this market.

The resolution source is the Chatbot Arena LLM Leaderboard (https://lmarena.ai/). If this source is temporarily unavailable, the market remains open until it is accessible again; if permanently unavailable, this market will resolve to "No".

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 ↑ 1520 currently trades at 63.5%, but our AI places its Fair Value at just 59.5%. This creates a large negative EV Gap of -4%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies ↑ 1550 as the premium value opportunity on the board. While the market only assigns it a 12.5% trading probability, our AI’s Fair Value assessment sits at 44.1% — yielding an impressive +31.6% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include ↑ 1600 (EV Gap: +7.8%) and ↑ 1700 (EV Gap: +7.3%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
