Joby Aviation shares jump after Toyota-backed manufacturing joint venture announcement

Joby Aviation’s stock climbed Tuesday after the company disclosed a manufacturing joint venture with Toyota Motor Corp. The announcement triggered a sharp market reaction, with Joby shares up roughly 7% in the session, according to the report published by Yahoo Finance on June 30, 2026.

The companies said the partnership is intended to support manufacturing of Joby’s electric aircraft, a category commonly referred to as electric vertical takeoff and landing aircraft, or eVTOLs. These aircraft are designed to take off and land vertically, using electric motors powered by onboard batteries, with the goal of reducing operating complexity compared with traditional helicopters while targeting lower per-trip energy costs compared with combustion engines.

While the report highlighted the existence of the manufacturing joint venture, it did not provide further specifics in the information available for this story about production capacity, locations, timing, or how costs and revenues would be split between the partners. Details of governance, milestones, and contract scope were also not included in the material reviewed here.

Toyota’s involvement is significant because large automakers bring manufacturing know-how, supplier relationships, and quality systems that can matter when scaling production from prototypes to higher-volume builds. For Joby, which is pursuing a path toward commercial air-taxi operations, the manufacturing angle is closely watched by investors because aircraft certification and ramp-up plans typically hinge on whether factories can deliver consistent, testable aircraft components at scale.

The eVTOL market remains a competitive, regulation-driven sector, and manufacturing partnerships are often viewed as a hedge against timeline risks. Investors have tended to reward announcements that suggest more concrete progress toward scalable production, even when commercial deployment timelines are still subject to safety reviews and operational clearances.

In the absence of additional disclosed terms in the report, it is still unclear how the joint venture will be structured, what portion of Joby’s supply chain Toyota will control, and whether the partnership is tied to specific aircraft models or production phases. The report also did not spell out whether the venture covers final assembly only, or also includes subassembly and component manufacturing.

Toyota and Joby have not provided, in the available post material reviewed for this story, further clarification on financial commitments, expected capital expenditures, or the near-term operational milestones that would indicate when aircraft produced under the arrangement could enter service.
