What happened

ADT (ADT) stock rose 34% on Thursday to $9.91 after OpenAI-backed Thrive Holdings agreed to a buyout at $10 a share in cash, valuing the home security firm at $15.3B with debt. The offer is 45.6% above ADT's $6.87 closing price on Oct. 27, before the deal news. The shares alone are worth about $7.6B. Apollo Global Management funds are providing all of the financing, and ADT will leave the stock market once the deal closes, expected in early 2027. ADT can look for rival bids until Nov. 28 (a “go-shop” period).

Why it matters

ADT is going from public markets to private ownership, and its new owner is backed by OpenAI, which supplies AI models and engineers to the companies Thrive owns. The deal shows AI-focused investors buying everyday businesses, like home security, to add new technology. For ADT shareholders, the $10 cash price is fixed, so the stock now trades just under it.
