This market will resolve according to the candidate who wins the nomination for the Democratic Party to contest the CO-08 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The Democratic primary will take place on June 30, 2026. If no nominee is announced by November 3, 2026, 11:59PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of official Democrat sources, including https://democrats.org/. Any replacement of the nominee before election day will not change the resolution of the market.State Rep. Manny Rutinel commands 83.5% trader consensus to win Colorado's 8th Congressional District Democratic primary on June 30, fueled by dominant fundraising—leading Democratic contenders fiscally as of early February—and recent labor endorsements, including SEIU Colorado and SEIU 105 on April 28, signaling union backing in this battleground race against Republican incumbent Gabe Evans. Former state Rep. Shannon Bird holds 13.5% amid her April 20-22 internal poll showing a narrow 25%-24% edge over Rutinel among likely voters, but markets discount it given high undecideds (45%) and Rutinel's momentum from party consolidation post-Yadira Caraveo's September 2025 withdrawal. Other candidates like Dave Young trail with negligible support as the field narrows.
