Booking Holdings (BKNG)

The sleeper story is marketing efficiency collapse masked by Middle East narrative - paid channel cancellations reveal underlying acquisition quality issues that extend beyond geopolitics. While US growth hitting low teens looks impressive, the Connected Trip deceleration from high 20s to high teens growth suggests their core cross-sell strategy isn't working despite massive AI investments. The binding constraint is product-market fit for multi-vertical bookings, not supply or marketing spend. Glenn's quote 'we have reduced our share count by over 40% in 12 years' while cutting guidance midpoints screams mature business returning cash because organic growth options are limited. My view changes if Connected Trip growth reaccelerates to 20%+ or they provide actual AI conversion uplift metrics with meaningful sample sizes.
