The global travel recovery has entered its next phase and so has the rivalry between Booking.com and Airbnb. What started as a clear divide between “hotels vs homes” has now become a fierce contest for share, scale, and traveller loyalty in the $200+ billion short-term rental (STR) market.
Over the past year, Booking Holdings (NASDAQ: BKNG), primarily through Booking.com’s alternative accommodation (AA) segment, has emerged as a serious challenger to Airbnb’s once-unquestioned dominance. Despite having fewer listings, Booking is driving far higher conversion, faster growth, and superior monetization quietly eroding Airbnb’s first-mover advantage.
Booking.com’s Quiet Rise in Alternative Accommodations
In Q2 2025, Booking.com booked an estimated 114 million alternative lodging nights, representing a 10% YoY increase and accounting for ~37% of its total room-night mix. To put that in perspective, Airbnb reported 134.4 million total nights and experiences, meaning Booking.com’s alt business now generates roughly 85% of Airbnb’s total booking volume despite having only ~8.4 million listings vs Airbnb’s ~10+ million.
That translates into significantly higher listing efficiency more nights per property, better utilization, and greater revenue productivity for hosts. Over the last six quarters, Booking’s alternative accommodation listings have grown steadily from ~7.4 million to 8.4 million, or about 8% YoY, while maintaining a strong instant-book share (~70%) and integrating “request-to-book” APIs to onboard additional non-instant supply.
In terms of geography, Booking’s alt business remains dominant in Europe (48% market share) and continues to expand rapidly in APAC, while in the U.S. (where it currently holds only 8% market share), its urban short-term rental push is gaining traction.
Airbnb: Slowing Growth, New Bets
While Airbnb (NASDAQ: ABNB) remains the category leader, its growth story is maturing. In Q2 2025, Airbnb’s “Nights & Seats” grew just 7% YoY, following 8% in Q1, marking its fifth straight quarter of mid-single-digit expansion.
CEO Brian Chesky has acknowledged the slowdown but sees it as temporary. Looking ahead to FY26, he expects topline growth to reaccelerate “at least in the teens,” powered by three major initiatives:
· International Expansion: 70% of Airbnb’s bookings still come from just five countries, leaving vast room to grow overseas.
· Experiences & Services: Airbnb believes both can become multi-billion-dollar verticals, targeting locals as well as travellers.
· Hotel Integration: The addition of HotelTonight’s boutique hotels into Airbnb’s core “Homes” tab expands inventory into traditional OTA territory.
Philosophically, 2025 remains an investment year for Airbnb focused on product expansion, international reach, and refining its app and platform experience.
Comparing the Numbers: Booking vs Airbnb
Room Nights & Growth: Booking has now added more absolute room nights than Airbnb for five consecutive quarters.
· Booking’s alt lodging business grew ~10% YoY in Q2, adding an estimated 10–11 million nights.
· Airbnb’s nights grew 7% YoY, or about 9 million additional nights.
Supply & Listings: Despite fewer listings, Booking’s utilization is materially higher.
· Booking: 8.4M listings (+8% YoY).
· Airbnb: ~10M listings (+7–8% YoY).
GMV Scale (Q2’25): Booking’s alternative accommodation GMV is growing faster, more efficiently, and now makes up three-fourths of Airbnb’s total GMV
· Booking Alt Accommodation: US$17.3B
· Airbnb Total: US$23.5B
Monetization / Take Rate: Booking is now monetizing slightly better per transaction.
· Booking: ~14.5% of gross bookings (boosted by payments / merchant model).
· Airbnb: ~13.2%, up slightly YoY.
ADR & Pricing: Airbnb commands a pricing premium, but Booking wins on scale and occupancy.
· Booking: Alt ADR in the $120–$138 range more mid-market, family-friendly, regional.
· Airbnb: ADR in the $170s, reflecting premium homes and inclusion of experiences revenue.
Geography: Both are diversifying globally, but Airbnb’s largest market (U.S.) is maturing.
· Booking: Leads in Europe and APAC; expanding U.S. presence.
· Airbnb: Strong in North America, growing faster in Latin America (high-teens) and APAC (mid-teens).
Platform Strategy: Booking’s model is transactional and ecosystem-driven; Airbnb’s is experiential and community-driven.
· Booking: Focuses on conversion efficiency, payments integration, Genius loyalty, and ecosystem unification (flights, hotels, rentals, cars).
· Airbnb: Expanding its lifestyle ecosystem through Experiences, Services, and hotel integration to raise spend per trip.
Booking’s Strategic Advantage: Scale + Efficiency + Ecosystem
Booking’s strength in alternative accommodations stems from its ability to scale supply, boost conversion, and monetize through payments and loyalty. Its AI-powered “Connected Trip” vision aims to create a seamless, automated travel experience, while AI-driven efficiencies are expected to deliver $400–$450 million in annual savings by FY27. With over 220 million Genius loyalty members driving more than half of bookings, Booking holds a strong retention and monetization edge that Airbnb currently lacks.
Airbnb’s Challenges: A Maturing Core, No Loyalty, and Rising Competition
Airbnb’s core home-sharing business is maturing, with slower growth in developed markets and rising competition from professional OTAs like Booking. The platform’s lack of a loyalty program, reliance on individual hosts, and renewed focus on home sharing may limit its appeal to travellers seeking consistency. As the STR market matures, Airbnb’s early lead is fading, and the gap in efficiency and monetization with Booking is rapidly closing.
The Road Ahead: Booking Playing Offense, Airbnb Reinventing
Booking’s alternative accommodation business now stands at ~85% of Airbnb’s scale, but is growing faster, converting better, and monetizing more efficiently. Its strategy expanding supply, embedding payments, unifying hotels and homes, and leveraging AI to cut costs positions it as the undisputed all-in-one travel platform.
Airbnb, meanwhile, is betting on international expansion, Experiences, Services, and hotel integration to reaccelerate growth into the mid-teens by FY26. It remains a beloved consumer brand with immense optionality, but the core lodging engine is slowing, and without a loyalty program or monetization uplift, its valuation premium (~30% to Booking.com) is increasingly hard to defend.
Final Thoughts: Airbnb built the category; Booking is industrializing it.
Airbnb remains the more aspirational brand, but Booking is proving to be the more efficient business. As the global STR market matures, the competitive playbook is shifting from storytelling to scale, from community to conversion. And in that world, Booking.com looks better positioned to win the next phase of travel.
