Trader consensus on Polymarket strongly favors U.S. Senator Michael Bennet as the Democratic nominee for Colorado governor, with 80.5% implied probability, driven by his high name recognition, proven statewide victories, and perceived frontrunner status in an open primary following term limits for incumbent Jared Polis. Attorney General Phil Weiser holds 17.5% on his executive experience and prior electoral strength, while lesser-known contenders like David Hughes and William Moses linger below 3% amid minimal momentum. No major declarations or polling shifts have emerged in the past 30 days for the June 2026 primary, leaving markets to price early speculation; upcoming candidate announcements or fundraising reports could reshape odds in this nascent race.
