Bedrock Robotics reportedly seeks $600 million at $3.5 billion valuation

Bedrock Robotics, which retrofits excavators to dig without an operator in the cab, is raising $600 million in Series C funding, Axios reported Tuesday. The publication says Bedrock is targeting a $3.5 billion pre-money valuation and attributed the terms to a source. The financing hasn’t been announced as closed.

The San Francisco startup’s Bedrock Operator adds sensors, computers and autonomy software to contractors’ existing equipment in a same-day installation without permanent changes. A site manager provides the initial plan; the system then reads the terrain, plans the excavator’s motions and performs earthmoving tasks. Builders can automate machines they already own instead of replacing their fleets.

Bedrock said in August that equipped excavators were operating autonomously on three live projects: a Nevada water-treatment facility with Sundt Construction and two Texas earthwork jobs with Champion Site Prep and Zachry Construction. Those deployments followed a year of supervised testing. The important step wasn’t another controlled demonstration; it was removing the operator from the cab on working sites.

The company started with excavation because earthwork sits at the front of a construction schedule; concrete, steel and other phases wait for it. Its product targets contractors that need more use from existing equipment and scarce skilled crews. Bedrock says the same underlying system is eventually intended to extend to dump trucks, dozers and loaders and coordinate work across fleets.

Axios’ report comes about eight months after Bedrock announced a $270 million Series B at a $1.75 billion valuation. Axios described the new target as a twofold jump from that February mark. It also follows Bedrock’s move from a supervised deployment that had shifted more than 65,000 cubic yards in 2025 to its first claimed operator-out projects. Axios did not identify prospective Series C investors in the publicly readable portion of its report.
