Full analysis
The 2026 election cycle is heating up with prediction markets showing a clear split: Democrats are heavily favored to reclaim the House (84¢ on CONTROLH-2026-D), while Senate control is a knife's edge (CONTROLS-2026-D at 48¢, R at 51¢). The Texas Senate race (SENATETX-26-D at 49¢, R at 50¢) is the most liquid individual race, reflecting its pivotal role. Other battlegrounds include Michigan (SENATEMI-26-D 64¢, R 36¢), Maine (SENATEME-26-D 69¢, R 30¢), and South Carolina (SENATESC-26-R 86¢). The balance-of-power combo markets are also active: Unified Republican control at 15¢, unified Democratic control at 46¢. The Democratic margin of victory in the House popular vote (KXHOUSEPOPVOTEMARGIN) shows a tight range at 1¢ for a 1-2% margin. This data suggests traders expect a Democratic House pickup but a divided government overall, which has implications for fiscal policy and regulatory outlook.
