OpenAI Odessia acquisition: Sonder founder’s AI travel agent sold as Expedia and Airbnb shares fall

The OpenAI Odessia acquisition emerged on Tuesday 10 November 2026, when Francis Davidson, the Sonder co-founder who built the AI travel agent Odessia, announced on X that he is joining OpenAI to work on travel, TechCrunch reported. Financial terms were not disclosed. Online travel shares fell the same day.

What happened

TechCrunch said Davidson made the announcement himself and described the deal as looking like an acqui-hire. When TechCrunch published, OpenAI had not announced the deal. The Next Web reported on 11 November that an OpenAI spokesperson confirmed the acquisition and called Davidson “a proven founder who has built multiple businesses to help people travel.”

Odessia’s service has already closed. The Next Web said its website now states the service “is no longer available.” The same report said Odessia opened to the public on 14 October with a free text-message concierge that could plan and book flights, hotels and full itineraries, ran on OpenAI’s GPT-5.5 and Codex models, and held IATA accreditation, which lets an agency issue airline tickets.

Travel stocks moved on the news. Investing.com reported, citing a report from The Information, that Expedia fell as much as 5%, Booking Holdings as much as 3% and Airbnb as much as 3.5% as shares hit session lows on Tuesday. PYMNTS reported Expedia down nearly 4%, Booking down more than 2% and Tripadvisor down more than 3% on the day.

Key numbers

• $6 million: the pre-seed round Odessia raised, led by Sequoia, according to TechCrunch.
• More than $60 million: annualised travel that tens of thousands of early users planned on Odessia over the summer, according to Davidson, as The Next Web reported.
• Up to 5%, 3% and 3.5%: intraday falls in Expedia, Booking Holdings and Airbnb shares on 10 November, per Investing.com.
• Nearly 4%, more than 2% and more than 3%: the falls in Expedia, Booking Holdings and Tripadvisor shares reported by PYMNTS.

Who is Francis Davidson and what was the Odessia AI travel agent

Davidson founded Sonder in 2014 as a college student. The company leased apartments in major cities and rented them out like hotel rooms, a model TechCrunch likened to Airbnb. It went public through a SPAC, but Davidson later said it did not raise as much money as it needed. TechCrunch reported that he resigned as CEO in June 2025, that a key Marriott partnership fell through, and that Sonder went bankrupt and wound down, as Business Insider reported in November 2025.

Odessia was his next company. TechCrunch said it was founded about a year before the deal and launched its AI travel agent about five months earlier. It sits at the point where the artificial intelligence and logistics and travel industries meet. Large AI launches have already moved listed incumbents this week: Microsoft shares fell after Anthropic launched new products, as we covered in our report on the Microsoft stock drop after the Claude Sheets launch.

What people said

Davidson said, in comments carried by PYMNTS, “Using AI to plan and book extraordinary trips is now a reality.” The Next Web reported that he said he would join OpenAI “to focus on the future of travel.”

OpenAI has not published its own account of the deal beyond the spokesperson comment reported by The Next Web. TechCrunch noted that OpenAI counts Booking.com, Expedia and KAYAK as customers or partners.

What happens next

The OpenAI Odessia acquisition leaves a central question open. According to The Next Web, it is unclear what OpenAI will do with the technology and whether ChatGPT will handle bookings directly. The report added that the deal coincided with OpenAI’s launch of Businesses in ChatGPT, which lets companies sell through the chatbot. TechCrunch said OpenAI has not announced any travel-specific product. Travel investors will be watching for that announcement, and for any change in how Expedia, Booking Holdings and Airbnb work with ChatGPT.
