LONDON, September 2, 2026, 15:21 BST —
- Booking Holdings traded at $198.13, up 1.25%, at 10:04:59 EDT.
- Which? said a fake 10 Downing Street listing accepted a test payment.
- Booking.com says its systems remove most fraudulent listings within 24 hours.
- The platform carried about 4.7 million properties at June 30.
Booking Holdings Inc. NASDAQ:BKNG shares rose 1.25% to $198.13 on Wednesday morning. The gain came after a Which? investigation said Booking.com accepted payment for a fake 10 Downing Street listing.
The opening response suggests investors view the test as a control problem, not yet an earnings shock. Scale raises the stakes. Booking.com carried about 4.7 million properties at June 30.
Which? created the listing on June 18 and briefly opened requests. Fourteen people asked about a stay during that 20-minute window. A researcher then completed a test booking and later posted a 10-out-of-10 review.
The consumer group said Booking.com removed the listing on August 27. Booking.com called the exercise a limited test. The company said its checks remove most fraudulent listings within 24 hours.

Which? urged Ofcom to investigate the platform under Britain’s Online Safety Act. Ofcom told the group that platforms must remove illegal user content swiftly once aware. It did not announce an investigation.
The regulator can impose large penalties after a proven breach. Its published enforcement ceiling is £18 million or 10% of qualifying worldwide revenue, whichever is greater.
Booking enters that debate with strong cash generation. Second-quarter gross bookings reached $51.0 billion, up 9%. Revenue rose 8% to $7.4 billion, while free cash flow increased 16% to $3.6 billion.

Adjusted EBITDA rose 9% to $2.6 billion. Its margin expanded 0.4 percentage points to 36.0%. Chief Executive Glenn Fogel said the “underlying desire to travel remained resilient” in the earnings release.
Verification costs could test that leverage. Booking.com listed more than 4.1 million alternative properties within its 4.7 million total. The company’s quarterly filing warns that added customer-service and partner costs can reduce alternative-accommodation margins.
Technology spending was already rising. Information-technology expense reached $263 million last quarter, from $219 million a year earlier. Marketing expense also increased to $2.37 billion.
Analysts remain constructive. Google Finance shows 22 buy ratings, six holds and no sells from 28 analysts. Their average target is $235.67, 18.95% above the quoted price.

The latest scrutiny is not isolated from earlier security risk. Booking said in April that unauthorized parties accessed some guest booking data. It remediated the issue and notified data-protection authorities.
Risks: Which? ran a controlled exercise and blocked automatic public bookings. Booking says that setup prevented some controls from triggering. No Ofcom case has been announced, while stronger shares signal limited immediate concern.
Investors will now weigh remediation against third-quarter guidance. Booking expects revenue, gross bookings and adjusted EBITDA to grow 4% to 6%. Any higher verification burden would matter most if it narrows that margin path.
