ADT, which installs and monitors security systems in homes and small businesses across the U.S., has agreed to be bought by Thrive Holdings, a company that OpenAI owns part of. The two companies announced the all-cash deal on Thursday, Oct. 29. Thrive Holdings buys established businesses, keeps them for the long term and changes how their work gets done with new technology. It says it already does this at more than 75 businesses in accounting, IT services and the building and construction trades.
ADT's shareholders would get $10 a share, 45.6% more than the stock's closing price of $6.87 on Oct. 27, two days before the announcement. That values ADT's shares at about $7.6 billion. The companies value the whole deal at $15.3 billion, which a news report says includes ADT's debt. Funds managed by affiliates of the investment firm Apollo Global Management have committed all of the financing. ADT, which has more than 12,000 employees, would become a private company and leave the New York Stock Exchange.
OpenAI's connection is through the buyer: in December 2025, OpenAI took a stake in Thrive Holdings and said it would place its own research, product and engineering teams inside Thrive's companies, starting with accounting and IT services, where it said the large volume of routine, rule-based work meant its tools could help right away. OpenAI has not said how big its stake is. Thrive Holdings was founded by Joshua Kushner, who also founded the investment firm Thrive Capital.
Thrive says it sees a chance for new technology to help cut false alarms, make alerts more informative for the monitoring staff who respond, and spot equipment problems earlier. The companies say ADT's data and privacy policies will stay the same and that no new sharing of customer data will happen without customers' permission.
The companies say Thrive's own engineers will work alongside ADT's staff to look for ways technology can improve its products and service. Neither announcement mentions OpenAI or AI, says what technology Thrive plans to bring, or says whether OpenAI's teams will work at ADT. The deal is expected to close in the first quarter of 2027, once ADT's shareholders and U.S. competition regulators approve it and other usual conditions are met. Until Nov. 28, ADT may seek offers from other buyers, with up to 10 more days for some bidders, and it can drop this deal for a better one under conditions set in the agreement.
