Currently, Democrat is dominating the market with an overwhelming 64% chance of winning. Republican follows in second place at 37%. The betting volume for this specific market has already reached $552.1K, 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

• Democrat (64%): Currently commanding the highest probability, Democrat 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 $338.2K in volume.

🥈 Tier 2: The Primary Challengers

• Republican (37%): Positioned as the most viable alternative, Republican maintains a 37% chance of resolving true. Its “Buy Yes” shares currently trade at 37¢.

This market will resolve according to the winner of the 2026 midterm Maine U.S. Senate election, inclusive of any run-offs.

A candidate shall be considered to represent a party in the event that he or she is the nominee of the party in question. Candidates other than the Democratic or Republican nominee (e.g., Greens, Libertarian, independent) may be added at a later date.

Candidates who run as independents will not be encompassed by the “Democrat” or “Republican” options regardless of any affiliation they may have with the party.

The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources call the race for the same candidate. If all three sources haven’t called the race in this state for the same candidate, this market will resolve based on the official certification.

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.

• The Most Overvalued Outcome Democrat currently trades at 64%, but our AI places its Fair Value at just 52.7%. This creates a large negative EV Gap of -11.3%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
