90% — Will Bernie Sanders endorse Antonio Delgado in the 2026 New York gubernatorial election before Nov 3, 2026 Leader: Cori Bush at 90% · Kalshi 90% · 13 contracts · $110 volume · medium confidence Updated 2026-06-08 07:51:04 UTC Tracks the leading outcome in a winner-take-all prediction market set with 13 outcomes. Why this matters: This market asks whether Bernie Sanders will publicly endorse Antonio Delgado for New York governor before Election Day 2026. At 31% probability, the market suggests it's unlikely but plausible. Sanders has a history of selective endorsements in gubernatorial races, often backing candidates aligned with his progressive platform. Delgado, the current New York Lieutenant Governor, would need to secure Sanders' support through demonstrated policy alignment or a formal request. The divergence between venues (Kalshi at 33%, Polymarket at 24%) reflects genuine uncertainty about Sanders' endorsement strategy in 2026. The main factor driving this probability is whether Delgado emerges as the clear progressive candidate in New York's race and actively seeks Sanders' backing. Key uncertainty centers on whether Sanders will focus his limited endorsement capital on federal races versus state contests. Resolution will occur either through Sanders making an explicit public endorsement or the election passing without one. Key factors: - Sanders has endorsed selectively in gubernatorial races; his 2022 pattern and 2026 priorities remain unclear - Delgado's positioning as a progressive candidate and whether he actively pursues Sanders' endorsement - The competitive structure of the 2026 New York gubernatorial race and whether it attracts Sanders' involvement - Sanders' overall endorsement bandwidth in 2026, given potential focus on federal Senate or presidential races - Public statements or campaign communications from Delgado's team indicating pursuit of high-profile progressive endorsements Contracts: - Will Bernie Sanders endorse Cori Bush in the 2026 MO-1 House election before Nov 3, 2026?: Cori Bush — 90¢ Kalshi $0 (weight 0%) - Will Bernie Sanders endorse James Talarico in the 2026 United States Senate election in Texas before Nov 3, 2026?: James Talarico — 80¢ Kalshi $0 (weight 0%) - Will Bernie Sanders endorse Gina Hinojosa in the 2026 Texas gubernatorial race before Nov 3, 2026?: Gina Hinojosa — 79¢ Kalshi $0 (weight 0%) - Will Bernie Sanders endorse Charles Booker in the 2026 United States Senate election in Kentucky before Nov 3, 2026?: Charles Booker — 71¢ Kalshi $0 (weight 0%) - Will Bernie Sanders endorse Nithya Raman in the 2026 Los Angeles Mayoral race before Nov 3, 2026?: Nithya Raman — 47¢ Kalshi $110 (weight 100%) - Will Bernie Sanders endorse Dan Osborn in the 2026 United States Senate election in Nebraska before Nov 3, 2026?: Dan Osborn — 43¢ Kalshi $0 (weight 0%) - Will Bernie Sanders endorse Josh Turek in Iowa Senate Race before Nov 3, 2026?: Josh Turek — 32¢ Kalshi $0 (weight 0%) - Will Bernie Sanders endorse Juliana Stratton in the 2026 United States Senate election in Illinois before Nov 3, 2026?: Juliana Stratton — 27¢ Kalshi $0 (weight 0%) - ... and 5 more --- ## Methodology SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question.
