A related healthcare subsidy need not meet the extension definition. - The tax-credit law deadline was December 31, 2025 at 11:59 p.m. ET. House control follows the 2026 election, with a Speaker-based fallback if control is ambiguous.

This should be analyzed as a joint contract with a historical condition and an electoral condition, rather than two fresh future forecasts. The selected joint outcome combines whether qualifying enhanced ACA credits were extended by law before the end of 2025 with which party controls the House following the 2026 election.

The event had $408,063 in cumulative volume. These are a dated price snapshot and event-wide turnover, respectively. [1](https://polymarket.com/event/aca-credits-extended-house-winner-2026)[2](https://polymarket.com/event/aca-credits-extended-house-winner-2026/will-aca-premium-tax-credits-not-be-extended-and-will-the-democratic-party-win-the-house-in-2026) The event contains multiple separate contracts. The selected quote should not be treated as an exhaustive ranking of all outcomes, and each contract’s own terms remain relevant. [1](https://polymarket.com/event/aca-credits-extended-house-winner-2026)[2](https://polymarket.com/event/aca-credits-extended-house-winner-2026/will-aca-premium-tax-credits-not-be-extended-and-will-the-democratic-party-win-the-house-in-2026) The API reported event-level liquidity of $101,234 at retrieval. That aggregate does not establish the executable depth or spread of this individual position.

A related healthcare subsidy need not meet the extension definition. The useful checks are the qualifying law and its signature date; the exact policy branch in the selected contract. Those checks connect the public story to the settlement condition instead of treating attention as confirmation.

House control follows the 2026 election, with a Speaker-based fallback if control is ambiguous. [2](https://polymarket.com/event/aca-credits-extended-house-winner-2026/will-aca-premium-tax-credits-not-be-extended-and-will-the-democratic-party-win-the-house-in-2026) The contract can accept a narrowed extension but excludes a substitute subsidy that does not extend the specified credits. That detail narrows the question being priced and is worth checking before comparing this contract with a broader political prediction.
