Joby Aviation (NYSE: JOBY), a producer of electric vertical takeoff and landing (eVTOL) aircraft, went public through a merger with a special purpose acquisition company (SPAC) on Aug. 11, 2021. Its stock opened at $10.62 per share, set a record high of $20.39 on Aug. 4, 2025, but now trades at about $9. It initially impressed investors with its progress toward commercial eVTOL flights, but its luster faded amid delays and regulatory challenges. Elevated interest rates, geopolitical conflicts, and other macro headwinds exacerbated that pressure.
With a market cap of $9.2 billion, Joby still looks expensive at 83 times this year's sales. However, I believe one catalyst could drive its stock much higher over the next five years.

Joby's S4 eVTOL can carry a single pilot and four passengers, travel up to 150 miles on a single charge, and reach a maximum speed of 200 miles per hour. The S4 can travel faster and farther than its closest competitor, Archer Aviation's (NYSE: ACHR) Midnight eVTOL, because it uses tilt-rotor propellers that alternate between lifting and cruising modes. The Midnight is heavier because it uses separate propellers for lifting and cruising.
Joby has completed test flights in the U.A.E., South Korea, and Japan. It's already backed by big investors and customers, including Toyota (NYSE: TM), Delta Air Lines (NYSE: DAL), and Uber (NYSE: UBER). Toyota will help Joby mass-produce its eVTOLs, Delta will use the S4 as a "last mile" airport-to-home air taxi service, and Uber will integrate those flights into its app. It also holds a $131 million contract with the U.S. Department of Defense.
Joby has plenty of irons in the fire, but it can't ignite them with the government's approval. Joby expects the Federal Aviation Administration (FAA) to fully approve its first commercial flights in the U.S. in late 2026. It also plans to launch its first air taxi flights in Dubai this year, even though the Middle East conflict might disrupt and delay those plans.
If the FAA finally clears Joby's S4 for commercial flights, its revenue could skyrocket over the next few years as its eVTOLs replace traditional helicopters. That's why analysts expect its revenue to surge from $53 million in 2025 to $458 million in 2028.
But that could just be the beginning. According to Eve Air Mobility's recent Global Market Outlook, there could be 30,000 eVTOLs in the air carrying three billion passengers globally by 2045. So even though Joby's stock looks expensive today, it could still soar a lot higher. Assuming it matches analysts' expectations through 2028, grows its revenue at a 30% CAGR through 2031, and trades at 30 times its current year's sales by the final year, its stock could more than triple over the next five years.

Four leading AI models discuss this article
"Late-2026 FAA approval is unlikely to produce profitable scale fast enough to justify JOBY's current valuation amid execution and competitive risks."
The article bets FAA certification by late 2026 will unlock rapid revenue growth from $53 million in 2025 to $458 million by 2028, driving a triple in JOBY shares. Yet the stock already trades at 83x forward sales with a $9.2 billion market cap despite no commercial flights. Key missing context includes repeated certification delays across the eVTOL sector, Archer Aviation's parallel progress, and the capital-intensive path to scaling manufacturing with Toyota. Geopolitical risks in Dubai and unproven passenger demand at scale add further uncertainty. Historical SPAC-era peers show certification rarely produces immediate profits.
If the FAA hits the 2026 target and Uber/Delta integrations generate visible bookings, the 30x sales multiple assumed for 2031 could prove conservative rather than optimistic.
"Joby’s current valuation already prices in aggressive, uncertain eVTOL adoption; any regulatory or execution hiccup could crush the stock as revenue ramps fail to meet stretched expectations."
The piece leans into a 2026 FAA green light as a near-certain catalyst, but Joby’s upside hinges on a broad, unproven eVTOL adoption curve. Valuing JOBY at ~83x current-year sales leaves little margin for error: any delay in certification, slower-than-expected demand, or higher unit costs could trigger a sharp multiple contraction. The TAM projections (30,000 eVTOLs by 2045) are speculative and depend on massive infrastructure, pilots, safety approvals, and favorable regulatory alignment across regions. Competition from Archer, uncertain partner execution (Toyota, Delta, Uber), and the cost of scaling manufacturing raise real probability of cash burn outpacing revenue. In short, the rally hinges on a fragile, stretched bet on a niche market becoming mainstream swiftly.
Even if FAA approval comes, the other dominoes—operational infrastructure, pilot training, and launch in multiple regions—could lag, depressing near-term revenue. The market may overestimate how quickly a luxury air-taxi becomes a mass-market utility.
"The current valuation assumes a flawless regulatory timeline that fails to account for the massive, ongoing capital dilution required to bridge the gap between prototype and commercial scale."
The article relies on a 'best-case' regulatory roadmap that ignores the brutal capital intensity of aerospace manufacturing. Trading at 83x forward sales, JOBY is priced for perfection, yet it remains a pre-revenue venture in a sector where certification delays are the norm, not the exception. While the Toyota and Delta partnerships provide institutional credibility, they do not solve the 'unit economics' problem: the cost of battery degradation and high-frequency maintenance for eVTOLs remains unproven at scale. Investors are essentially betting on a 2026 FAA inflection point that, if delayed by even 18 months, would necessitate significant equity dilution to fund operations, crushing existing shareholders.
If Joby successfully achieves FAA type certification, the 'first-mover' advantage in the urban air mobility market could create an insurmountable moat, justifying a premium valuation as they cannibalize the regional helicopter and luxury ride-share markets.
"Regulatory approval is necessary but not sufficient; the real risk is that Joby proves the eVTOL market is fundamentally uneconomic at the scale and price points required for 30,000 aircraft by 2045."
The article's bull case hinges entirely on FAA approval in late 2026 as a binary catalyst, but glosses over the harder problem: unit economics at scale. Joby trades at 83x sales with $53M revenue and a $9.2B market cap—that's a $173k revenue per dollar of market cap, implying razor-thin margins assumed away. The 30% CAGR growth assumption through 2031 requires not just regulatory approval but solving manufacturing, pilot labor costs, and demand elasticity at $200+ per seat. Dubai launch this year is a tell: they're avoiding FAA scrutiny by launching overseas first, suggesting U.S. approval timelines are optimistic. The article also ignores that competitors (Archer, Lilium, Joby itself) are burning cash at scale with no proven path to profitability.
If FAA approval lands on schedule and Toyota's manufacturing muscle delivers unit costs below $5M per aircraft, Joby's addressable market (airport shuttles, emergency transport) could justify current valuation within 3-5 years—the article's tripling thesis isn't absurd if execution matches the hype.
"Pilot labor shortages represent a larger near-term constraint on JOBY's 2028 revenue target than certification timing."
All four overlook pilot supply constraints. FAA data shows commercial helicopter pilots already face 15-18 month training queues; scaling to 500+ JOBY aircraft by 2028 requires thousands of new type-rated pilots whose salaries alone could exceed $180 per flight hour. This labor bottleneck hits unit economics harder than battery degradation and would force Archer and Joby into bidding wars that compress the 30% CAGR assumptions.
"Pilot-supply bottlenecks are real, but cross-border certification, maintenance labor, and regulatory cadence can cap utilization and raise unit costs, threatening the 30% CAGR and 2028 revenue target."
Grok’s pilot-supply call is credible, but it’s not the sole friction. Training queues aside, cross-border certification, maintenance labor, and regional regulatory cadence will cap aircraft utilization and push unit costs higher. If flight hours don’t scale, the 30% CAGR and 2028 revenue target look fragile, potentially forcing dilutive financing or accelerated subsidies that derail the thesis. The article’s optimistic lock on a 2026 FAA event ignores these knock-on effects.
"Applying automotive mass-production logic to aerospace certification risks a catastrophic quality control failure that the market is ignoring."
Grok and ChatGPT focus on labor, but you are all ignoring the 'Toyota factor' as a potential liability rather than an asset. Toyota’s involvement suggests a focus on automotive-style mass production, which is fundamentally incompatible with the bespoke, hyper-regulated nature of aerospace certification. If Joby attempts to force high-volume manufacturing before the FAA fully vets the airframe design, they risk a 'Boeing-style' quality control crisis that would permanently destroy the brand’s credibility and capital runway.
"Toyota's presence may constrain speed-to-market more than it guarantees manufacturing excellence."
Gemini's Toyota-as-liability angle is sharp, but understates one thing: Toyota's actual leverage here. They've invested $394M and hold board seats—they're not forcing Joby into premature scaling; they're incentivized to protect certification timelines. The real risk is the opposite: Toyota's risk-aversion could slow iteration cycles, ceding first-mover advantage to Archer, who's moving faster with less manufacturing overhead. That's the execution trap nobody flagged.
The panel consensus is overwhelmingly bearish on Joby's stock, citing repeated certification delays, unproven demand, high capital intensity, and labor supply constraints as key risks. They agree that the stock's valuation (83x forward sales) leaves little margin for error.
