Marriott International

Marriott International, Inc. is the largest hotel company in the world by number of rooms, with approximately 9,000 properties across more than 30 brands in 140 countries. The company has approximately $25 billion in annual revenue (with much larger system-wide revenue counting franchised properties at approximately $90 billion+). Founded in 1927 by J. Willard Marriott as a root-beer stand (the Hot Shoppes restaurant chain) and entering the hotel business in 1957 with the first Marriott Hotel in Arlington, Virginia, the company trades on NASDAQ as MAR with a market capitalization of approximately $80 billion as of 2026 and employs approximately 411,000 workers globally (across managed properties; the franchised-property staff are not Marriott-employed).

Marriott's brand portfolio spans the Luxury tier (Ritz-Carlton, Ritz-Carlton Reserve, JW Marriott, EDITION, St. Regis, The Luxury Collection, W Hotels, Bulgari Hotels), Premium tier (Marriott, Sheraton, Westin, Le Méridien, Renaissance, Autograph Collection, Tribute Portfolio, Delta Hotels, Marriott Vacation Club), Select tier (Courtyard, Four Points, SpringHill Suites, Protea, Fairfield, AC Hotels, Aloft, Moxy), and Long Stays (Residence Inn, TownePlace Suites, Element). The 2016 acquisition of Starwood Hotels & Resorts ($13.6 billion) added the Sheraton, Westin, St. Regis, and W brands. The Marriott Bonvoy loyalty program has approximately 210 million members globally — the largest hotel-loyalty program by membership.

Marriott's AI strategy has been publicly accelerated through 2024-2025 with the Anthropic Claude partnership announcement (deploying generative AI across guest-services and operations workflows) plus continued internal AI development. AI applications include: revenue management (heavily ML-driven across all 9,000 properties), customer-service automation (the Marriott Bonvoy app uses AI for routine inquiries), personalization (room-rate offers, package recommendations, on-property service suggestions), property-operations AI (predictive maintenance for HVAC and elevators, energy management), and Bonvoy loyalty marketing (heavy ML for offer personalization). The company has also invested in AI-driven event-and-meeting-planning tools — the Marriott group-business segment is one of the largest in the industry. Going forward, Marriott's AI focus areas include continued generative-AI deployment with Anthropic, on-property guest-experience personalization, and increasingly AI-augmented direct-bookings to compete with the OTAs (Booking.com, Expedia) for booking economics.
