ACHR vs JOBY Stock Comparison 2026: Archer Aviation vs Joby Aviation: AI Score, Valuation, Performance and Upside
Archer Aviation and Joby Aviation are both electric air taxi companies pursuing FAA certification for urban air mobility. Joby has more airline partnership depth (Delta, prior Uber Elevate) and Toyota manufacturing support; Archer has United Airlines backing and Stellantis manufacturing. Both are pre-revenue and in the certification phase — the comparison comes down to which FAA certification path, manufacturing partnership, and launch market strategy is most credible.
ACHR vs JOBY is a comparison of the two most advanced US eVTOL companies — both pursuing FAA certification for electric air taxis, both backed by major automotive and airline partners, both pre-revenue. This is a speculative bet on which company reaches commercial launch first and at sufficient scale to establish a defensible air taxi network.
ACHR holds the edge across 3 of 5 key metrics in this comparison. ACHR leads on both 1-year return (-44.86%) and forward P/E quality (-6.91x vs -10.61x for JOBY), a relatively favorable combination of momentum and valuation.

- prefer Archer's United Airlines and Stellantis partnerships as manufacturing and airline launch customer validation
- value Archer's UAE market international optionality if US FAA certification extends longer than expected
- want eVTOL air taxi exposure with a smaller market cap offering potentially higher upside if Midnight achieves commercial certification
- are comfortable with pre-revenue status, FAA certification timeline uncertainty, and intense competition from Joby, Wisk, and others
- prefer Joby's more established partnership portfolio — Toyota manufacturing, Delta airlines, and US Air Force operational experience
- value Joby's Uber Elevate heritage providing earlier air mobility market development work and operational insights
- want the eVTOL company with the largest and most credible manufacturing-to-commercial-launch partnership stack
- are comfortable with pre-revenue status, FAA novel certification process risk, and higher valuation reflecting Joby's partnership depth

| Core business | Archer Aviation is developing Midnight, a 4-passenger electric vertical takeoff and landing (eVTOL) aircraft targeting urban air mobility markets. Archer has a strategic partnership with United Airlines (order for up to 200 aircraft) and Stellantis (manufacturing support). The company is pursuing FAA type certification for commercial operations. Archer has also announced a partnership to potentially launch air taxi routes in UAE markets. | Joby Aviation is developing a 4-passenger plus pilot eVTOL aircraft targeting urban air mobility. Joby has a multi-year partnership with Toyota (manufacturing scale-up support) and was acquired from Uber Elevate, giving it Uber's air mobility platform and market development work. Delta Air Lines has invested in Joby and is a planned airline launch partner. Joby is also piloting operations with the US Air Force and aims to be among the first commercial eVTOL operators. |
| Investor focus | Investors track FAA type certification progress, Midnight flight test milestones, manufacturing readiness with Stellantis, and commercial agreements with airlines and mobility operators. | Investors track FAA Stage 1–5 certification milestone progress, flight test frequency and data results, Toyota manufacturing ramp partnership milestones, and Delta launch route plans. |
- United Airlines partnership provides both commercial validation and a clear launch customer path for initial air taxi routes
- Stellantis manufacturing partnership leverages automotive scale and production expertise for Midnight aircraft assembly
- UAE market partnership provides an alternative international launch market if US FAA certification timelines extend
- Toyota partnership provides world-class manufacturing scale and reliability engineering for transitioning from prototype to mass production
- Delta Air Lines as a commercial partner provides airport gate access, passenger routing, and launch market integration
- US Air Force contract work provides real-world operational experience and federal government credibility for civilian certification
- FAA certification for novel eVTOL aircraft is an unprecedented regulatory process — timeline extends could delay commercial launch significantly
- All eVTOL companies are pre-revenue and pre-commercial — significant capital requirements remain before any aircraft flies commercially
- Joby, Lilium, Wisk, and Overair compete in the same eVTOL space — only a small number of players will achieve viable commercial operations
- FAA type certification for eVTOL aircraft is novel — Joby's path is among the most advanced but still faces unprecedented regulatory review
- Pre-revenue, pre-profitability with significant ongoing capital requirements through certification and initial commercial launch
- eVTOL market faces range, battery energy density, and cost economics constraints that must be overcome for mass-market adoption at competitive price points
