AI writes 60% of Airbnb's code; the revenue side is still an IOU
Ex-Meta Llama chief Ahmad Al-Dahle just put the first hard numbers on Airbnb's AI-native rebuild, and two banks re-rated the stock the same week. Of the three AI theories now riding on the shares, only the cost story faces a clean test on Nov 5.

The cost ledger already has numbers on it
Ahmad Al-Dahle spent 2023 to 2025 launching Meta's Llama models, then crossed to Airbnb as chief technology officer in January 1. His first quantified account of the "AI-native" rebuild: 60% of Airbnb's code is AI-authored, feature output is up nearly 80% year over year, and the average engineer files about 1.6x the pull requests 1. The compounding shows in build times. The grocery service shipped first, an eight-to-nine-month build; the learnings, stored in an internal context graph called Everest, let the airport-pickup team ship in about six weeks 1.
The P&L is starting to carry it. Second-quarter revenue was $3.61B, up 16.5%, and operating margin rose to 21% from 19.8% a year earlier 2. Support is where AI touches costs most directly: tickets resolved with no human went from about a third at the end of 2025 to nearly 45% in Q2, roughly half now by the CTO's count, and per-booking support expense fell 16% year over year 134.
Tickets solved with no human went from a third to nearly half in nine months

| Tickets resolved by AI, % of total | |
|---|---|
| End-2025 | 33% |
| Q2 2026 | 45% |
| Now, per CTO | 50% |
From 6% to 18% in five quarters
The top line turned at the same time. Growth slowed to 6.1% in Q1 2025, then reaccelerated to 17.9% in Q1 2026 and 16.5% in Q2 2. Management credits the shift to AI-powered infrastructure 4; the filings do not isolate that effect.

The ad money is still an IOU
The bull case beyond the cost story rests on a product Airbnb has not yet launched: sponsored listings 5. Jefferies analyst John Colantuoni read the AI search launch as evidence the company is "closer to launching sponsored listings," worth 300-plus basis points of long-term take-rate expansion at nearly 100% incremental EBITDA margin, and reiterated a $215 target 5. Brian Chesky has called it "a pretty easy straight shot to $1 billion incremental high margin revenue" 6. The catch: agents may not care. Instinct, a booking agent valued at a reported $2.5 billion, says paid placement carries no weight in its choices 6.
Meta is the risk KeyBanc's upgrade cannot value
KeyBanc upgraded the same week to overweight at $191, resting its case on durable core growth, hotels as a second engine and Airbnb as an "AI beneficiary," at 14.1x 2028 EV/EBITDA against a 16.7x three-year median 7. The overhang is Al-Dahle's old desk. Muse books travel and shops for users 8, is spreading across Macs and glasses with travel and payments connectors 9, and Meta is giving away 5,000 Home Link gadgets and free small-business access to seed it 8. Shares fell about 7% on 23 September after news that Muse can complete bookings on its own; the 5 to 10% of bookings Muse might eventually capture is an analyst projection, not observed behavior 4.
Only one theory meets an earnings statement
On 5 November, after the close, the third-quarter print can settle the cost theory in a line item 10. The ad line and the moat will still be opinions with price targets attached.
