Analysis

All 8 agents agree Democrats are strongly favored (range 66-92%, mean 82.4%). The evidence is specific, verifiable, and multi-layered: Cook 'Likely D' rating with ~95% historical accuracy, two-term incumbent with improving margins (52%→54.4%), D+3 PVI, opposition-party midterm advantage, weak GOP field locked in after filing deadline, and Kalshi at 93%. The market at 58% appears severely mispriced - to justify 42% Republican odds you'd need to ignore incumbency, Cook ratings, partisan lean, and midterm dynamics simultaneously. Agent 1's lower estimate (66%) reflects excessive hedging on early-cycle uncertainty; Agents 2 and 7 at 92% may slightly overweight Cook accuracy without enough discount for time remaining. I set 85% as a well-supported estimate that accounts for residual uncertainty while recognizing the overwhelming structural Democratic advantage. The 27-point edge over market price is unusually large and well-supported.
