In the protracted race for certification, four of the front-running eVTOL developers continue to expand the envelope of their flight-test prototypes. However, while Archer Aviation, Eve Air Mobility, Joby Aviation, and Vertical Aerospace continue to progress with their programs, cash considerations remain an inevitable headache.

First-quarter 2026 results revealed more.
