**McDonald’s Q3 2026 global comparable sales are expected to land in the 1–2% range, the leading outcome priced at 53.5% on Polymarket.** This reflects Q2 results of 1.3% global growth (U.S. +0.8%, International Operated Markets +1.5%, International Developmental Licensed +1.9%) and continued pressure from weak U.S. traffic tied to inconsistent value-menu execution and elevated pricing sensitivity among lower-income consumers. International segments are projected to show modest sequential acceleration from Q2 levels, supporting the overall print near the middle of the 0–3% band. Recent peer results underscore the contrast: Restaurant Brands International posted 3.8% system-wide comparable sales in its Q3, led by an 8.4% U.S. gain at Burger King driven by aggressive value promotions. McDonald’s Q3 report, due November 4, will serve as the immediate catalyst, with traders focusing on U.S. guest counts, check growth, and any updates to full-year guidance amid a broader quick-service slowdown.
