What happened
Booking Holdings stock fell 5% Wednesday, hitting a session low of $155.37, after Expedia announced a partnership with Meta's Muse AI assistant that lets users book hotels and trips through Muse.
Why it matters
Booking has no comparable Muse partnership right now, so investors worry that if AI agents like Muse start booking trips on their own, it could weaken the direct customer relationships Booking depends on.
What to watch
The selloff reflects three hits at once — the Expedia-Muse deal, Erste Group Bank's cut to Booking's fiscal 2027 earnings estimates, and the EU General Court upholding a ruling that blocked Booking's roughly $1.9 billion ETraveli acquisition. Watch whether Booking responds with its own AI strategy or partnerships.
WHO IT HITSBooking Holdings shareholders and travel-sector investors are absorbing the selloff, while travel booking platforms that rely on direct customer relationships face pressure to secure their own AI assistant partnerships.

Booking Holdings stock had already been under pressure before Wednesday's drop. Erste Group Bank cut its fiscal 2027 earnings estimates for the company the day before the Expedia-Muse news broke, and the EU's General Court recently upheld an antitrust ruling that blocked Booking's roughly $1.9 billion deal to acquire ETraveli Group. That ruling closed off a path for Booking to expand into flight bookings and is still weighing on the stock's growth outlook.
The wider market added to the pain. The Nasdaq fell 1.1% and the S&P 500 dropped 0.6% as investors turned cautious, with travel stocks hit especially hard and Booking among the biggest decliners in the group. Booking stock is now trading much closer to its 52-week low of $150.14, a sign of how much sentiment has soured this month.
The key question is whether Booking can respond with its own AI strategy or partnerships to stay competitive as AI-powered travel booking becomes a bigger part of the industry. Whether the selloff fades or keeps building appears to hinge on that response, and on whether investors treat the Expedia-Muse deal as a one-off headline or the start of a broader shift in how travelers book trips.
