Massachusetts Senate Race 2026 — Live Prediction Market Odds
Massachusetts is a safe Democratic hold with Ed Markey running for re-election. The market prices it as a formality; the only genuine contest a trader would watch is a Democratic primary challenge, which shows up in the nomination market rather than the general. As a general-election contract it is a calibration anchor for what near-certainty looks like on the board.

How to read this
Each contract pays $1 at resolution, so the price in cents is the market’s implied probability — a 58¢ contract is a 58% chance. When the leading price sits near 50¢, the market is telling you the race is a genuine coin flip.
Massachusetts Senate 2026 — frequently asked
Who is favored to win the Massachusetts Senate race in 2026?
The live board above shows the current market favorite — read each contract’s price as the market’s implied probability, so a 55¢ contract is a 55% chance. Going into the cycle the seat is held by Ed Markey (Democrat) and rated safe d; because a real-money market reprices continuously, take today’s favorite off the price, not a static rating.
