Monarch is the wound-down anchor of DEPLOY's agriculture cohort: a tractor that reached genuine commercial shipping and $220M+ funding, then collapsed and was acquired for assets by Caterpillar, in the same spirit as the discontinued Amazon Scout, Cruise, Zebra/Fetch, and SAM100 records.
✔
The historical peak is real: the MK-V shipped to paying commercial customers from December 2022 (Constellation Brands took six for its To Kalon vineyard), on more than $220 million raised. That commercial peak is preserved as history.
Price
No reviewed price is on record. We do not treat unverified analyst estimates as pricing data. There is no consumer price, and the company is discontinued. The MK-V was B2B agricultural equipment, not a product sold to consumers, so DEPLOY records zero price points.
Availability
Discontinued
Monarch Tractor is discontinued. The MK-V shipped to commercial customers from December 2022, but Monarch collapsed through 2025; its assets and IP were acquired by Caterpillar around April 2026.
Real-world status
Monarch Tractor (founded 2018, Livermore, California) built the MK-V, a fully battery-electric, driver-optional smart tractor with a WingspanAI fleet-management and remote-supervision layer. It is the wound-down anchor of DEPLOY's agriculture cohort. The MK-V did reach a genuine historical peak: it shipped to paying commercial customers starting December 2022 (the first being Constellation Brands, six tractors for its To Kalon vineyard), and Monarch raised more than $220 million anchored by a $133 million Series C in July 2024 (recorded at commercial maturity historically). But Monarch collapsed through 2025: its Foxconn manufacturing arrangement ended (the Ohio plant was sold to SoftBank in August 2025), with layoffs and a shutdown warning in November 2025, a pivot to roughly 70% licensing revenue, and finally an assignment for the benefit of creditors; its assets and IP were acquired by Caterpillar around April 14, 2026, in an asset-and-technology purchase, not 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, 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.
⚠
Two verified-vs-claimed points. On status: Monarch collapsed through 2025 (Foxconn manufacturing ended, layoffs and a shutdown warning, an assignment for the benefit of creditors) and its IP was acquired by Caterpillar (~April 2026) in an asset purchase, not a going concern. On autonomy: 'fully autonomous' was overstated: full autonomy was a narrow dairy feed-pushing case, general field work was driver-assist, and an Idaho dealer sued in September 2025 alleging the tractors could not operate autonomously.
⊘
There is no consumer price, and the company is discontinued. The MK-V was B2B agricultural equipment, never sold to consumers, so DEPLOY records zero price points.
