Elevated oil prices near $93 per barrel for WTI as of mid-October 2026, well above the $80 threshold, combined with stalled progress on a full Strait of Hormuz stabilization agreement, anchor trader sentiment around the dominant “no agreement or oil ≥$80” outcomes. Ongoing U.S.-Iran tensions, Iranian targeting of unauthorized shipping routes, and incomplete implementation of the June 2026 memorandum have sustained supply disruptions and risk premiums, keeping the probability of oil falling below $80 before the November midterms low. In this environment, Democratic Senate control carries an implied 58.5% probability versus 32.6% for Republicans, consistent with broader prediction-market and polling aggregates showing Democrats favored to gain the four net seats needed for a majority. The low-weighted “agreement plus oil below $80” scenarios (under 10% combined) reflect limited near-term catalysts capable of shifting both variables simultaneously.
