Republican majorities in both chambers of the 119th Congress, combined with sustained party discipline, have prevented any successful veto override of President Trump’s actions to date. Early 2026 override attempts on measures such as water-infrastructure and reserved-area bills fell short in the House despite some bipartisan margins on other legislation. With narrow GOP edges and no signs of sufficient cross-party defections, the two-thirds threshold remains difficult to reach before the end of the session. Traders therefore assign a high probability that Congress will not override any veto through December 2026.
