Twelve billion dollars. Gone. The top ten eVTOL companies have collectively burned through $12 billion in investor capital — four times what was lost during the very light jet craze of the late 1990s, and six times Boeing’s entire annual profit. Not one of them has carried a paying passenger. The number comes from a cumulative deficit analysis of the industry’s publicly traded players: Joby Aviation ($2.66 billion), Archer Aviation ($1.8 billion), Vertical Aerospace ($1.5 billion), and the now-insolvent Lilium ($1.5 billion) lead the pack. Behind them, a string of smaller players have burned through hundreds of millions more on prototypes, test flights, and regulatory lobbying. The question the industry refuses to answer honestly: is this the dawn of urban air mobility, or the most expensive science fair in aviation history?

The Money Trail

Joby Aviation is the front-runner and the biggest spender. The company, backed by Toyota and partnered with Uber for air taxi operations, has burned through $2.66 billion developing its five-seat, six-rotor electric aircraft. It has flown thousands of test hours and holds an FAA Part 135 air carrier certificate — but certification of the aircraft itself remains incomplete. Archer Aviation follows with $1.8 billion spent. The company completed flight testing in the UAE and plans commercial service in Miami, Los Angeles, and Abu Dhabi. But Archer also faces a patent lawsuit from Wisk (now part of Boeing), and its path to FAA type certification has been longer than promised. The most dramatic casualty is Lilium, the German eVTOL maker that raised $1.5 billion before filing for insolvency in late 2024. The company’s jet-powered VTOL concept attracted massive investment but proved technically and financially unviable. Its assets were acquired by new investors who are attempting a restart — but the $1.5 billion spent by the original company is gone.

The Very Light Jet Parallel

Aviation veterans see echoes of the very light jet (VLJ) craze of the early 2000s. Companies like Eclipse Aviation, Adam Aircraft, and DayJet raised billions on the promise that cheap, small jets would democratise private aviation. Eclipse alone burned through $1 billion before bankruptcy. The VLJ bust destroyed roughly $3 billion in total investor capital — a third of what eVTOL companies have already consumed. The counterargument: eVTOLs have better technology, bigger markets, and more sophisticated backers. Joby’s partnership with Uber gives it a built-in ride-hailing network. Dubai and Saudi Arabia are building vertiports. China’s EHang has already received certification for autonomous passenger drones.

The Race to Revenue

The next twelve months will determine whether the $12 billion was visionary investment or expensive fantasy. Joby and Archer are both targeting commercial launches in 2026 — Joby in Dubai with Uber, Archer in Abu Dhabi. If paying passengers actually fly before the year is out, the narrative shifts from cash burn to market creation. But the physics of battery technology, the complexity of FAA certification, and the cost of manufacturing small, bespoke aircraft remain brutal headwinds. Even optimistic projections show years before any eVTOL company reaches profitability. For now, $12 billion sits on the burn side of the ledger. The revenue column is still empty.
