Bedrock Robotics, a US start-up that converts construction machines to work without a driver, has raised $600m in a Series C round that values it at $4.1bn. CapitalG, Alphabet’s growth fund, and Emergence Capital led the round, with Bessemer Venture Partners, Temasek and NVIDIA among the other investors. The company says it has now raised nearly $1bn in total.
Bedrock says its fully autonomous excavators began paid work on live commercial job sites in mid-August 2026, and that its customer volume has more than doubled since 2025. The contractor Haydon will use the system for fully autonomous earthwork at a remote site in Texas and plans to test trench work next, and recent contracts take Bedrock into seven more states, from Minnesota to Florida. The company did not say how many machines are working or how closely people supervise them.
Why it matters: this is a large bet that robots can earn money on building sites, not just in warehouses and on roads. Earthmoving is repetitive and can be dangerous; Haydon’s chief executive says “the biggest win is a safer, more predictable job site”. Bedrock says the money will expand deployments and build the field and operational support that autonomous machines need.
