2026 U.S. Senate Election: Democrats flip Republicans by March 31?

The 2026 midterm elections for the US House of Representatives is scheduled to be held on November 3, 2026. 

This market will resolve to "Yes" if Republicans hold fewer seats in the House of Representatives for any state that Trump won in the 2024 US presidential election as a result of the 2026 midterm elections. Otherwise, this market will resolve to "No". 

Initial seat counts will be based on the composition of the US House of Representatives as of November 2, 2026, 11:59PM ET.

This market's resolution will be solely based on the number of seats held by the Republican Party in the US House of Representatives for any state won by Trump in the 2024 Presidential election. The loss of particular district seats will not count towards a resolution for this market; only the total number of seats held by the Republican Party in a given state will be considered. (e.g. The loss of a particular district's seat by the Republican Party followed by the gain of another district's seat would not be sufficient to resolve this market to "Yes".)

​​A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democrat or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the House elections are conclusively called by this market's resolution sources.

For the purposes of this market, states won by Trump in the 2024 Presidential election include Alabama, Alaska, Arizona, Arkansas, Florida, Georgia, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Montana, Nebraska, Nevada, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, West Virginia, Wisconsin, and Wyoming. This list is determined by the winner of the electoral votes for each state in the 2024 Presidential election. In states such as Maine and Nebraska, where electoral votes are allocated separately by congressional districts as well as to the statewide winner, only the electoral votes allocated to the statewide winner are considered.

This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).

If a required runoff for any such election could change the market’s outcome, the market will remain open until that runoff is conclusively called by this market’s resolution sources.

A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources.

The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called all US House of Representatives elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on the official certification.

Will the Republican Party hold between 200 and 204 House seats after the 2026 midterm elections?

A majority in the House of Representatives means holding more than half of the currently seated voting members of the U.S. House at that time, excluding vacant seats. Ties do not qualify as a majority.  

The primary resolution source for this market will be official information from the United States House of Representatives Press Gallery (https://pressgallery.house.gov/member-data/party-breakdown); however, a consensus of credible reporting may also be used.

Will Republicans lose House majority before the midterms?

The 2026 midterm elections are scheduled to be held on November 3, 2026.

This market will resolve to “Yes” if, as a result of the midterm elections, the Republican Party controls the U.S. presidency, controls the U.S. House of Representatives, and holds at least 60 seats in the U.S. Senate.

This market will resolve based on the results of all Congress elections, including special elections, that are scheduled to occur in November 2026 as of October 31, 2026. If a required runoff for any such election could change the market’s outcome, the market will remain open until that runoff is conclusively called by this market’s resolution sources.

A party will be considered to have 'control' of the House of Representatives if it wins a majority of voting seats.

If control of the House is ambiguous given the above rules, this market will resolve according to the party affiliation of the first Speaker of the US House who is selected following the 2026 United States midterm elections.

A candidate's party is determined by their ballot-listed or otherwise identifiable affiliation with that party at the time the 2026 United States midterm elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democratic or Republican Parties will be considered a member of one of these parties based on the party that they most recently expressed their intent to caucus with at the time the 2026 United States midterm elections are conclusively called by this market's resolution sources.

If a Senate seat is vacant but a corresponding election is not held in November 2026, the seat will be considered held by the party of the seat's most recent incumbent.

The resolution source for this market is the Associated Press, Fox News, and NBC. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on the official certification.

The rules and resolution criteria are as follows:

1. Enhanced ACA premium tax credits extended in 2025?
Affordable Care Act (ACA) enhanced premium tax credits are set to expire at the end of 2025 if not extended by the federal government.

This market will resolve according to whether a bill extending the enhanced ACA premium tax credits beyond 2025 is signed into federal law by December 31, 2025, 11:59 PM ET. 

A qualifying bill may extend the enhanced ACA premium tax credits in any form, including shorter extensions, phased-down benefits, or narrowed eligibility, as long as the bill clearly continues enhanced premium tax credits that have wider eligibility and/or lower required income contributions relative to baseline ACA premium tax credits that would otherwise apply after 2025.

A bill replacing the ACA enhanced premium tax credits with an alternative form of healthcare subsidy, such as direct cash payments to a health savings account, will not qualify.

If the bill is signed into law before 2026, it will qualify to resolve this market, regardless of when it takes effect.

The primary source of resolution will be official information from the US federal government; however, a consensus of credible reporting may also be used.
