BTIG Estimate: Booking Leads Expedia in B2B Room Nights

BTIG analyst Jake Fuller estimates Booking Holdings' B2B business booked ~196 million room nights over the past 12 months, about 15% more than Expedia's ~170 million. Since Booking doesn't disclose B2B financials, the industry assumed Expedia led. However, the estimate is sensitive to assumptions; minor changes could put Booking below Expedia. Expedia's B2B is growing faster (high-teens vs. high-single digits) and offers more robust white-label products. Booking plans to consolidate its three B2B units in early 2027, potentially leading to clearer disclosure.
