If Ed Markey wins, the margin will be positive; if Ed Markey loses, the margin will be negative; if Ed Markey ties for first place, the margin shall be 0.\n\nEach margin range is inclusive of its lower bound and exclusive of its upper bound, and no rounding shall be applied. For example, for consecutive ranges of 5-6% and 6-7%, a margin of 5.99999% resolves within the 5-6% range, while a margin of exactly 6% resolves within the 6-7% range. If Ed Markey runs under multiple parties or is listed multiple times, votes attributable to the same underlying candidate will be summed.","image":null,"icon":null,"outcomes":["Yes","No"],"outcome_prices":[0.01,0.99],"probability":0.01,"spread":0.01,"active":true,"closed":false,"start_date":"2026-08-31T17:03:00Z","end_date":"2027-09-01T14:00:00Z","closed_time":"2027-09-01T14:00:00Z","volume":4491.42,"volume_24hr":0.0,"prob_24h_change":null,"volume_24h_change":null,"normalized_vol_24hr":null,"normalized_volume":22.01844024658203,"liquidity":null,"categories":["Elections"],"countries":["United States"],"updated_at":"2026-09-03T01:27:06.929340Z","fetched_at":"2026-09-03T01:27:06.929340Z","added_at":"2026-08-31T17:14:35.617050Z","url":"https://kalshi.com/markets/kxprimarymovd/massachusetts-democratic-senate-primary-margin-of-victory-ed-markey/kxprimarymovd-senatemad26emar","event_title":"Massachusetts Democratic Senate primary margin of victory?
