Full analysis
The 2026 midterm election landscape is coming into focus on prediction markets. Democrats are clear favorites to retake the House, trading at 78¢ (CONTROLH-2026-D) against Republicans at 22¢ (CONTROLH-2026-R). The Senate is far tighter: Republicans lead at 56¢ (CONTROLS-2026-R) versus Democrats at 42¢ (CONTROLS-2026-D), making it a genuine toss-up. The balance of power combinations are also active: 'D House, R Senate' is at 35¢ (KXBALANCEPOWERCOMBO-), while 'D House, D Senate' is at 40¢.
State-level races are drawing significant volume. The California Governor primary has Xavier Becerra (KXGOVCA-26-XBEC) at 89¢ to finish first, with Steve Hilton (KXGOVCA-26-SHIL) at 10¢. The Maine Governor Democratic primary saw a massive 44¢ move for Hannah Pingree (0x9eb4dd944ea38e1259) to 68¢, suggesting a late-breaking development. Her opponent Nirav Shah (0x906842f0acae58e863) crashed 27¢ to 21¢.
Key contracts to watch: - **Peru President: Keiko Fujimori** (0xc4c3dbcc37a957a817): 93¢, +3¢ — consolidating her lead, high volume at 1.48M - **Texas Senate: Ken Paxton (R)** (0x94521176f57d2ce81d): 59¢ — tight race with Democrat Talarico at 43¢ - **Maine Senate: Democrat** (0x66bbf6d55e02962788): 64¢, +2¢ — Democratic lean - **South Carolina Governor GOP Primary: Pamela Evette** (0xfec5e4fb10dd82bc4f): 25¢, +13¢ — gaining ground
The California Governor primary is especially interesting as a top-two system. Currently, Becerra and Hilton are the likely two to advance (the 'Dem-Rep' advanced parties contract is at 99¢). The 'Dem-Dem' scenario is at 0¢. Traders should monitor the 3rd place battle between Tom Steyer (0) and others for potential positioning.
