Caterpillar acquires assets of autonomous electric tractor startup Monarch Tractor

Caterpillar has acquired the assets of autonomous electric tractor startup Monarch Tractor, according to United States Patent and Trademark Office filings. The construction equipment manufacturer's purchase follows years of struggle for the agricultural technology company, which had raised more than $200 million since its 2018 founding. Monarch was established The startup's difficulties included multiple rounds of layoffs, lawsuits from three different dealers who claimed the tractors were defective and unable to operate autonomously, and the loss of its manufacturing partner Foxconn. The Taiwanese electronics giant had planned to produce Monarch tractors at a former General Motors plant in Ohio but sold the facility to SoftBank in August 2025. Internal conflict also plagued the company, with co-founder Mondavi stating he was "pushed out" last month after disagreeing with CEO Penmetsa's software-focused strategy. Mondavi said he wanted to address reliability issues through hardware changes, while Penmetsa believed software solutions were preferable. Monarch had attempted to pivot to a software services business model, restructuring to focus on licensing its autonomous technology after earlier manufacturing partnerships collapsed. The company auctioned off most of its remaining tractors earlier this year before Caterpillar's acquisition of its technological assets. Caterpillar declined to comment on the acquisition, while Monarch's CEO referred to a previous statement noting the company's technology had been acquired
