By early 2025, not a single electric vertical takeoff and landing aircraft has carried a paying passenger. The industry that promised to reshape urban mobility by mid-decade remains a collection of prototypes, test flights, and regulatory filings. After a wave of SPAC mergers in 2021 and 2022 sent share prices soaring, the companies behind those aircraft face a harder accounting: cash burn, approval delays, and in one case, outright insolvency.
Two broad categories define the electric aircraft sector: fixed-wing commuters and eVTOL air taxis. This survey covers the leading developers, their technological approaches, their financial trajectories, and the regulatory pathway that has so far held them all back.
Fixed-Wing Commuters vs eVTOL Air Taxis
The electric aircraft sector splits across a basic engineering divide: wings versus rotors. Commuter aircraft such as Eviation's Alice and Heart Aerospace's ES-30 operate like conventional airplanes but with electric or hybrid-electric powertrains. They need runways, which limits their operations to existing airports and airstrips. Their advantage is efficiency. Wings generate lift with far less energy than rotors, so these aircraft can carry more people or cargo over longer distances.
eVTOL aircraft, by contrast, take off and land vertically, like helicopters, but cruise using wings or tilting rotors. This lets them operate from helipads, parking garages, or purpose-built vertiports in dense cities. The trade-off is severe energy consumption during vertical lift, which constrains payload, range, and battery life. Most eVTOL designs carry four to five passengers and aim for ranges of 30 to 80 kilometers, roughly a fifth of what an electric commuter plane might target.
Joby Aviation, Archer Aviation, Lilium, Vertical Aerospace, Eve Air Mobility, Wisk Aero, and Airbus all pursue eVTOL configurations. Heart Aerospace and Eviation are the best-known developers of electric commuter planes. The distinction matters for investors and regulators because the two categories face different approval rules, operating economics, and infrastructure requirements.
The SPAC Wave That Changed the Industry
Between August 2021 and May 2022, five eVTOL startups went public through mergers with special-purpose acquisition companies. Joby Aviation merged with Reinvent Technology Partners and began trading on the New York Stock Exchange on August 11, 2021. Archer Aviation merged with Atlas Crest Investment Corp and listed on the NYSE on September 17, 2021. Lilium merged with Qell Acquisition Corp and began trading on the Nasdaq on September 15, 2021. Vertical Aerospace merged with Broadstone Acquisition Corp and listed on the NYSE on December 16, 2021. Eve Air Mobility, spun out of Embraer, merged with Zanite Acquisition Corp and began trading on the NYSE on May 10, 2022.
The SPAC route gave these companies access to hundreds of millions of dollars in capital without the scrutiny of a traditional initial public offering. At the time, the valuations reflected optimism about rapid regulatory approval and early revenue flights. The market has since repriced that risk. By late 2024, the share prices of every publicly traded eVTOL company traded well below their SPAC-era peaks, and the gap between the best-capitalized firms and the rest had widened sharply.
The FAA's New Rules and the Long Wait
A New Aircraft Category
The Federal Aviation Administration regulated early eVTOL development under special conditions, adapting existing airplane and helicopter rules on a case-by-case basis. That changed in October 2024, when the FAA issued its final rule for powered-lift aircraft pilot qualification and operations, creating a regulatory pathway distinct from Part 23 airplanes and Part 27 helicopters. The rule defines a new category, powered-lift, and sets requirements for pilot training, operational limitations, and airworthiness. Europe's EASA has pursued a similar track, publishing its own proposed means of compliance for eVTOL type approval.
No One Has Crossed the Finish Line
Despite these advances, no eVTOL aircraft has achieved full FAA or EASA type approval as of early 2025. Joby Aviation and Archer Aviation are widely considered the closest to the finish line, with both targeting revenue launch in 2025. The approval process involves demonstrating that the aircraft can safely handle failure modes unique to electric propulsion, including battery thermal runaway, rotor failure during hover, and software integrity for fly-by-wire systems. Each of these requires months of flight testing and documentation that regulators review in detail.
Technological Approaches and Their Trade-Offs
Tilt-Rotor
eVTOL manufacturers have converged on three configurations, each with distinct energy and noise profiles. Tilt-rotor designs, used by Joby Aviation and Archer Aviation, rotate the entire propulsion unit from vertical to horizontal, using the same motors for lift and cruise. This is mechanically complex but efficient in forward flight.
Lift-Plus-Cruise
Lift-plus-cruise designs, used by Vertical Aerospace and Wisk Aero, separate the rotors into dedicated lift motors and cruise propellers. The lift rotors shut down during cruise, which reduces noise and mechanical wear but adds weight. Airbus unveiled its CityAirbus NextGen in 2021, a four-seat eVTOL with an 80 kilometer range using a lift-plus-cruise configuration. It remains a development project within the larger Airbus organization, which provides financial stability that startups lack.
Vectored Thrust and the Lilium Collapse
Lilium pursued a vectored-thrust approach with its Lilium Jet, using 36 small ducted fans mounted on the wings and canards that tilt as a unit. The design aimed for higher cruise speed and lower cabin noise than open-rotor alternatives, but the distributed propulsion system raised approval complexity and weight. In October 2024, Lilium's two main German subsidiaries filed for insolvency after the German government declined a loan guarantee. A deal to sell the assets to a consortium of investors was reached in December 2024, and the company exited insolvency in January 2025, but the interruption reset its development timeline.
Partnerships and the Reality of Orders
The United Airlines Bet
The industry's order book is a mixture of conditional pre-orders, memoranda of understanding, and letters of intent, few of which carry binding financial commitments. United Airlines placed the most prominent bet, a $1 billion conditional order for 200 Archer Midnight eVTOL aircraft in 2021, and later invested $15 million in Eve Air Mobility in 2022. The Archer order is contingent on the aircraft meeting performance and approval milestones, and like most such agreements, it allows the buyer to walk away without penalty if those milestones are missed.
A Backlog Without Revenue
Other airlines, rental car companies, and ride-hailing platforms have placed similar placeholder orders, but no manufacturer has recognized revenue from aircraft sales. The distinction between firm and conditional orders is rarely disclosed in detail, which makes it difficult to assess the true backlog. The only certainty is that no eVTOL has delivered a single revenue aircraft to any customer.
Incumbents, Startups, and the Cash Runway
The Incumbent Advantage
Major aerospace manufacturers have entered the eVTOL market through subsidiaries and spinouts, giving them advantages in engineering talent, regulatory relationships, and balance-sheet depth. Boeing controls Wisk Aero, which is developing an autonomous four-seat eVTOL and remains privately held. Airbus has its CityAirbus NextGen program. Embraer spun out Eve Air Mobility and took it public via SPAC in 2022. These incumbents can absorb development costs and delays that would threaten independent startups.
The Independent Leaders
Among independent companies, Joby Aviation and Archer Aviation have emerged as the two best-capitalized, with both targeting revenue launch in 2025. Their cash positions, disclosed in quarterly filings, give them the runway to reach approval without raising additional capital at distressed valuations. Other publicly traded firms face a harder path. Vertical Aerospace's funding situation remained uncertain as of early 2025.
The Fallen and the Pivoted
Lilium's insolvency in late 2024 demonstrated that the gap between a plausible prototype and revenue approval can consume more cash than the market is willing to supply. Weaker players have already left the public market or shifted strategy. Heart Aerospace abandoned its original all-electric 19-seat ES-19 design, announced in 2022, and pivoted to a 30-seat hybrid-electric regional aircraft called the ES-30, acknowledging that battery technology was not advancing fast enough to make the all-electric version viable. Eviation's Alice completed its first flight on September 27, 2022, at Moses Lake, Washington, but has not announced a firm production timeline.
