The enhanced ACA premium tax credits expired at the end of 2025 without congressional extension amid partisan disagreements over cost, eligibility reforms, and offsets in a Republican-controlled Congress. This outcome has driven sharp drops in marketplace enrollment for 2026, consistent with CBO projections, while multiple extension proposals advanced in the House but stalled in the Senate. Trader consensus on the paired House outcome reflects the typical midterm dynamic favoring the opposition party under a Republican administration, with recent generic ballot polling showing Democrats ahead by roughly five to six points and most forecasts assigning them a strong edge for a majority. The lower probability attached to Republican House retention aligns with narrower GOP paths in competitive districts and redistricting effects.

This market will resolve according to the combined outcome of whether enhanced ACA premium tax credits will be extended in 2025 (https://test8298192.pages.dev/event/enhanced-aca-premium-tax-credits-extended-in-2025?) and according to which party will win the House in 2026 (https://test8298192.pages.dev/event/which-party-will-win-the-house-in-2026?).
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.
2. Which party will win the House in 2026?
This market will resolve according to the party that controls the House of Representatives following the 2026 U.S. House elections scheduled for November 3, 2026.
House control is defined as having more than half of the voting members of the U.S. House of Representatives.
If the outcome of this election is ambiguous given the above rules, this market will remain open until the Speaker of the House is selected following the 2026 U.S. general election, at which point it will resolve to the party the Speaker is affiliated with at the time of their election to that position. If the elected Speaker does not caucus with any listed party this market will resolve “Other”.
Determination of which party controls the House after the 2026 U.S. House elections will be based on a consensus of credible reporting, or if there is ambiguity, final federal and/or state election authority certification or other final official determination of the 2026 election results.The enhanced ACA premium tax credits expired at the end of 2025 without congressional extension amid partisan disagreements over cost, eligibility reforms, and offsets in a Republican-controlled Congress.
