Candidates not formally affiliated with the Democratic or Republican parties will be considered aligned with one based on their publicly declared intent to caucus.\n\nIf control of the House is unclear under the above rules, control will be determined by the party affiliation of the first Speaker of the House elected after the 2026 midterms.\n\nIf control of the Senate is unclear, it will be determined by the party affiliation of the first Senate Majority Leaderelected after the 2026 midterms.\n\nThis market will resolve once Associated Press, Fox News, and NBC News have all conclusively called the outcomes of both chambers. If these sources do not reach consensus, the market will resolve based on the results certified by official government sources.","image":null,"icon":null,"active":true,"closed":false,"start_date":"2025-07-21T23:47:23.634000Z","end_date":"2026-11-04T07:59:00Z","closed_time":null,"volume":67328.56431755511,"volume_24hr":400.93725561151615,"volume_24h_change":null,"normalized_vol_24hr":18.99325942993164,"normalized_volume":46.397525787353516,"liquidity":5000.0,"open_interest":null,"categories":["Politics","Elections"],"tags":["us-politics","elections","politics-default","2026-us-congressional-elections"],"synthetic":false,"is_group":false,"group_key":null,"parent_event_id":null,"probability":null,"spread":null,"top_outcome":"Democrats
