Marriott’s Q3 2026 worldwide RevPAR performance is shaped by sustained U.S. and Canada strength, where Q2 comparable systemwide RevPAR rose 3.4% year-over-year with 5% growth in the region driven by broad ADR gains across chain scales and customer segments. International results lagged at -0.5%, weighed by a sharp Middle East decline tied to regional conflict, though luxury brands continued to outperform globally. In its August earnings release, Marriott guided for 3.5–4.0% Q3 worldwide RevPAR growth and lifted full-year 2026 expectations to 3–3.5%, citing persistent travel demand and World Cup-related lifts in June and July. Q3 earnings, due shortly, will provide the actual figure amid ongoing luxury resilience and potential softening in lower-tier U.S. segments. Traders are monitoring these releases alongside broader lodging data for any deviation from the company’s implied trajectory.
