Condition: Republicans win a majority of seats in the U.S. House of Representatives in the November 3, 2026 elections (at least 218 seats won by Republican Party candidates, counting delegations as certified; independents count for neither party). If Democrats or no party win a majority, this market resolves N/A.

Resolves YES if Donald Trump vetoes five or more bills or joint resolutions during calendar year 2027, counting regular and pocket vetoes as listed in the U.S. Senate's record of presidential vetoes. Resolves NO otherwise.

This is one half of a conditional pair; its twin asks the same question if Democrats win the House. Comparing the two shows what the market thinks control of the House changes.

Starting probability is a seed, not a forecast: anchored on public prediction-market prices where a related market exists, otherwise a prior.
