D.R. Horton taps Promise Robotics to build 1,250 homes in Arizona

D.R. Horton, the largest U.S. homebuilder by volume, signed a multi-year deal with Promise Robotics to use its robotic factories for framing more than 1,250 homes. All the homes will be built in metro Phoenix, where that equals over half a year of the builder's local closings; financial terms were not disclosed.

• Promise Robotics will assemble wall panels at a factory in Gilbert, Arizona
• 1,250 homes is about 1.5% of D.R. Horton's 84,863 closings in fiscal 2025
• Factory-as-a-Service model: the builder rents capacity instead of owning a plant
• The platform has run in Calgary since September 2025 with Mattamy Homes
