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

• Ed Markey (75%): Currently commanding the highest probability, Ed Markey is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 75¢, signaling a high degree of market conviction. This contract alone has generated $68.4K in volume.

• Alexander Rikleen (0.4%): Sitting in third place with a 0.4% probability, the market shows measured skepticism toward Alexander Rikleen, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~17.5%)

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 Ayanna Pressley (0.1%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like Ayanna Pressley are still attracting notable interest.

This market will resolve according to the winner of the Democratic Primary for United States Senator from Massachusetts.

If no 2026 Massachusetts Democratic Senate Primary takes place, this market will resolve to "Other".

The resolution source for this market will be the first announcement of the results from the Massachusetts Democratic party, however an overwhelming consensus of credible reporting may suffice.

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 Ed Markey currently trades at 75%, but our AI places its Fair Value at just 59.6%. This creates a large negative EV Gap of -15.4%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies Alexander Rikleen as the premium value opportunity on the board. While the market only assigns it a 0.4% trading probability, our AI’s Fair Value assessment sits at 21.1% — yielding an impressive +20.7% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include Ayanna Pressley (EV Gap: +12.9%) and Seth Moulton (EV Gap: +0.9%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
