Senate control at 52c R — fade GOP premium, buy Democratic spread
The Senate control market sits at a near-coin-flip (52c R / 48c D) per highlight data, yet individual state markets show Democrats leading in Michigan (57c), Georgia (92c), and Ohio (51c). The weighted implied Democratic probability across key battleground seats exceeds 52c, meaning Senate GOP control is slightly overpriced relative to state-level aggregation. Sell GOP Senate control as a spread against the state-level book.
Democrats are heavy favorites at 85c for House control while Senate is a coin-flip at 52c Republican, creating a structural spread between chambers that contagion gaps in individual district races have not yet closed. The MN-2 lagging market at 19c is dramatically out of step with correlated district triggers showing 60–76c gaps, representing a pure contagion lag edge. Senate and House control markets offer a mean-reversion spread for sophisticated positioning.
