Brian Chesky wants Airbnb to be the Amazon of travel. He added hotels, car rentals, grocery delivery, and airport pickups to the app this week. The press release reads like a wish list.

The more interesting question is why Airbnb, which built a $78 billion company by being different from traditional travel booking, decided to stop being different.

That's what this really is. Airbnb is becoming an online travel agency. The same kind that Booking.com and Expedia have been for two decades. Except Airbnb has $12.2 billion in revenue and a fraction of the infrastructure those companies spent decades building.

Chesky told a reporter in September that there is "no Amazon for services" and that Airbnb is the one to fill that gap. Then last week's summer release dropped hotels in 20 cities, car rentals, grocery delivery through an Instacart partnership, airport pickups, luggage storage, and FIFA World Cup experiences. All in one update.

The surface logic is clean. Home sharing is supply-constrained. Hosts burn out, cities crack down, neighborhoods fight back. Hotels fill the gaps where homes can't go. Car rentals and local services capture more of each trip. If you book a home, find a restaurant, and rent a car on the same app, you're getting more value and Airbnb gets a bigger cut.

The problem is the counterfactual nobody is asking: what made people choose Airbnb in the first place?

It wasn't convenience. Booking.com can book your hotel, your flight, and your car from day one. Airbnb won because staying in someone's apartment in Paris felt different from staying in a chain hotel. The product was the difference.

Now Airbnb is selling boutique hotels in Paris. Same city. Same app. The distinction between "stay in a home" and "stay in a hotel" collapses when both live on the same screen. If Airbnb becomes a place where you book anything travel-related, then the thing that made you open the app instead of Booking.com starts to vanish.

There's a structural reason Airbnb is targeting independent and boutique hotels specifically rather than big chains. Independent hotels pay 15 to 30 percent in OTA commission rates. Big brands pay 10 to 15 percent. Airbnb needs the margin. This tells you something about the economics: Airbnb isn't going after hotels because it has a better product for hotel bookings. It's going after hotels where the take rate is highest.

CFO Ellie Mertz confirmed on the Q1 2026 earnings call that hotel room nights are growing fast. She outlined three reasons hotels are now core: filling supply gaps, supporting growth, and attracting new customer segments. That's honest framing. Airbnb ran out of rooms in some markets and needs something to fill the space.

The results so far justify the ambition. Q1 2026 revenue hit $2.68 billion, up 18 percent year-over-year, and above guidance. Gross booking value was $29.2 billion, and the average daily rate rose 9 percent. Management raised full-year guidance to low-to-mid-teen revenue growth. The machine is humming.

But humming doesn't mean defensible.

Booking Holdings trades at roughly three times Airbnb's market cap. It has the hotel inventory, the airline partnerships, the car rental infrastructure, and the cross-selling flywheel already built. Expedia has the same playbooks, just smaller scale. Airbnb is now asking these companies to defend turf they've owned for twenty years - except Airbnb is the one knocking on their door, not the other way around.

The Amazon analogy breaks on a simpler point. Amazon works because physical goods follow predictable logistics. A shoe box ships the same way from Portland to Omaha. Services don't work that way. A car rental in Rome depends on a local partner's inventory. Grocery delivery depends on Instacart's network. Airport pickups depend on drivers showing up. Airbnb is aggregating services it doesn't control, from partners whose margins are already squeezed by other OTAs. It's building a concierge layer on top of other people's operations.

Airbnb Is Becoming the Thing It Was Supposed to Replace

Some of this will work. Hotels are probably necessary. The supply constraint on home sharing is real, and if a guest arrives in Barcelona and can't find a home that fits, a hotel listing keeps them on the app instead of opening Booking.com. That's a rational retention play.

But car rentals, grocery delivery, and airport transfers are a different category of expansion. They're features, not a platform. And features don't create moats. Booking.com will add whatever Airbnb adds. It has the scale to do it faster and the partner relationships to do it cheaper.

I suspect the real test isn't whether Airbnb can add these services. It's whether doing so changes what users think the company is. Right now, Airbnb is the app you open when you want something that feels different from a normal hotel stay. If the app becomes the place you book everything - including normal hotel stays - then Airbnb has won the expansion and lost the differentiation.

The market has assigned Airbnb a $78 billion market cap. That's a vote of confidence in the current model. The question is whether the future that Chesky is building commands that same multiple or the smaller one that belongs to a generalist travel aggregator with less inventory than Booking.com and less scale than Expedia.

Here's the test to watch: over the next two quarters, track Airbnb's bookings mix. If home sharing still dominates, the expansion is a supplement and the differentiation survives. If hotel nights and ancillary services start approaching home sharing as a share of total bookings, then Airbnb has officially become the thing it was supposed to replace - and the only question left is whether anyone will pay the same premium for it.
