MK-V

Monarch Tractor (founded 2018, Livermore, California; founder and CEO Praveen Penmetsa) built the MK-V, a fully battery-electric, driver-optional smart tractor with a WingspanAI fleet-management and remote-supervision layer. The registry records it at commercial maturity to reflect a genuine historical peak: the MK-V shipped to paying commercial customers starting in December 2022, the first being Constellation Brands, which took six tractors for its To Kalon vineyard, following an earlier 2021 pilot at Wente. Monarch raised more than $220 million (some reports up to roughly $251 million), anchored by a $133 million Series C in July 2024. The lifecycle state is discontinued, recording a major correction to the originating dispatch's framing of an active, growing manufacturer: Monarch collapsed through 2025, with its Foxconn manufacturing arrangement ending when the Ohio plant was sold to SoftBank in August 2025, layoffs and a shutdown warning in November 2025, a pivot to roughly 70 percent licensing revenue, and finally an assignment for the benefit of creditors. Its assets and intellectual property, including the software-defined vehicle platform and perception stack, were acquired by Caterpillar around April 14, 2026, in an asset and technology purchase with undisclosed terms rather than a going-concern acquisition. On autonomy, marketing of a fully autonomous tractor overstated reality: full autonomy was confined to a narrow dairy feed-pushing use case in outdoor feed lanes, while general field work was driver-assist with an operator aboard, and an Idaho dealer sued in September 2025 alleging the tractors could not operate autonomously, with Monarch's sales team reportedly conceding the limits in writing.

Claims ledger

Public, dated claims by Monarch Tractor, each tracked against the evidence. Status is a DEPLOY assessment from primary sources: verified means an independent source confirms it; contradicted means one refutes it; open means the outcome is not yet determinable.

Claim Integrity: 67% (2 of 3 resolved claims verified; 3 tracked)
  • VerifiedCustomer · claimed 2026-04-14
    Monarch Tractor Shuts Down Operations

    Company confirmed shutdown via social media post. Assets acquired by Caterpillar. The MK-V was a verified autonomous product but the company failed to achieve commercial scale and shut down in April 2026.

  • VerifiedCapability · claimed 2026-01-01
    The world's first driver-optional, data driven, and 100% electric tractor

    The MK-V was the world's first driver-optional electric tractor. This "first" claim is verified — no other company produced a driver-optional electric tractor before Monarch. However, the company is now defunct. https://www.monarchtractor.com/

  • ContradictedCapacity · claimed 2023-01-01 · deadline 2024-12-31
    The company expects to sell as many as 2,000 tractors by end of next year

    Monarch never reached 2,000 tractors. Revenue was ~$112M projected for 2024 (Forbes), but Caterpillar acquired Monarch, ending independent operations.
