Doubling Down on Autonomy, Caterpillar Acquires Self-Driving Electric Tractor Co. Monarch

Based in the San Francisco Bay area, Monarch Tractor had been called "the Tesla of agriculture" for developing what it called "the world's first fully electric, driver-optional, autonomous smart tractor." Valued at $500 million in 2024, it has had a bumpy ride since then—leading Caterpillar to acquire its core technology, according to Bloomberg.

In January, Irving-based Caterpillar (NYSE: CAT) made a splash at the annual CES conference in Las Vegas by announcing “a major leap forward” in its embrace of autonomous technology, planning a long lineup of “intelligent machines” that could transform construction worldwide—everything from excavators to loaders to dozers to haul trucks. Now it’s doubling down on that strategy by acquiring the technology of self-driving electric tractor startup Monarch Tractor, according to a Bloomberg report.

Based in the San Francisco Bay area, Monarch developed the MK-V, which it called “the world’s first fully electric, driver-optional, autonomous smart tractor.” The tractor’s software-based “control center” was driven by WingspanAI, an app-based digital agriculture tech platform for farm management, data collection, and analytics.

Founded in 2018, the startup had raised around $251 million from backers including Astanor Ventures, At One Ventures, and an affiliate fund of Taiwan-based Foxxcon, giving it a valuation of over $500 million in 2024. But the company ran into financial problems and legal setbacks recently that led to its manufacturing shutdown and acquisition by Caterpillar—the terms of which were not disclosed.

A ‘shift’ from manufacturing to tech licensing amid a bumpy ride

Monarch had been called “the Tesla of agriculture,” with good reason: Its co-founder and president, Mark Schwager, was a former Tesla employee who served as head of the Tesla Gigafactory, leading the project from concept phase to construction.

But Monarch has had a bumpy ride of late, leading it to cease its operations earlier this month following financial setbacks, lawsuits from dealerships, staff layoffs, and facility closures, according to reports by FarmProgress and others.

In a LinkedIn post last week, the company said it had “set out to push agriculture forward by building one of the first smart, electric, software-defined tractors. From by-wire systems to exportable power, V2G capability, and a camera-first autonomy stack, we had a clear mission: improve food sustainability and small farmer economics with a new global tractor architecture.”

However, Monarch conceded, “Building and scaling a new tractor platform in agriculture came with unforeseen challenges,” forcing the company to “make difficult decisions.”

The biggest decision of all is what led to the Bloomberg report: “We are also happy to share that Monarch’s core technology, including our software-defined vehicle platform, perception stack, and electrification systems, has been acquired by a large global equipment manufacturer,” Monarch said in the LinkedIn post. “It means the technology will continue to move forward.”

According to Bloomberg, Caterpillar has acquired Monarch’s core autonomous technology, not the tractor manufacturing business it had pursued for years.

Caterpillar has made other forays into autonomy

Caterpillar has made other moves in recent years toward a self-driving construction future.

In 2024, a collaboration among Caterpillar, Thiess, and WesTrac surpassed 1 million meters in autonomously drilling using three Cat drills at the Mt. Arthur South coal mine in New South Wales, Australia. The three drills used Cat MineStar technologies, and were managed by a single operator sitting in a remote operating station using Cat MineStar Command for drilling.

In 2023, Caterpillar collaborated with Phoenix-based Freeport-McMoRan to convert the mining company’s fleet of 33 massive Cat 793 haul trucks at its Bagdad mine in Arizona to an autonomous haulage system using Cat MineStar Command for hauling.
