ACHR vs JOBY: How Archer Aviation and Joby Aviation Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. ACHR and JOBY share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined ACHR and JOBY exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Archer Aviation designs and intends to manufacture and operate electric vertical-takeoff-and-landing (eVTOL) aircraft. Its flagship, Midnight, is a piloted four-passenger air taxi built for short urban hops of roughly 20 to 50 miles, recharging between flights, with the long-term plan to earn money two ways: selling aircraft to partners and operators, and running its own air-taxi network in launch cities. Alongside the passenger business, Archer has opened a defense lane, agreeing to supply its dual-use electric powertrain technology toward Anduril's Omen autonomous air vehicle program with UAE-based EDGE Group. The company remains pre-commercial: it is flight-testing aircraft and pursuing regulatory approval, not yet carrying paying passengers at scale.

Joby Aviation designs and intends to manufacture and operate electric vertical takeoff and landing (eVTOL) aircraft, small piloted air taxis built to carry a few passengers quietly over congested cities. Its plan is to make money as a vertically integrated transportation-as-a-service business: build its own aircraft (with manufacturing practices borrowed from partner and investor Toyota), then sell rides directly to passengers, distributed through partners like Uber and the Blade passenger business it acquired. Until its own aircraft enters revenue service, nearly all reported revenue comes from that acquired Blade helicopter operation rather than from eVTOL flights.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• ACHR drivers: Certification momentum; International launch via Abu Dhabi.
• JOBY drivers: Lead in FAA certification; Strategic backers and balance sheet.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Archer is effectively pre-revenue (roughly ~$1.6M reported in Q1 2026) while burning cash heavily, with a ~$217.7M net loss that quarter and operating cash use around ~$149M. For JOBY, joby is effectively pre-revenue on its core product: the bulk of its reported revenue comes from the acquired Blade helicopter business, not its own eVTOL aircraft, and it posted a net loss of roughly $110 million in Q1 2026.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick ACHR if you believe its drivers more; JOBY if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the ACHR and JOBY guides.

ACHR. For a development-stage company like Archer, the cash balance and the rate it is spent matter far more than earnings, because there are no meaningful earnings yet. The roughly ~$1.78B of liquidity against a quarterly cash burn near ~$149M is the runway clock that determines how long Archer can pursue certification before needing more capital. Conventional multiples like price-to-earnings do not apply; the relevant questions are milestone progress, dilution, and time to revenue.

JOBY. For a pre-commercial company, the most important figures are cash and burn rather than earnings: roughly $2.5 billion of liquidity against a few hundred million of cash use per half-year implies several years of runway, but no clear path to profitability yet. The reported revenue largely reflects the acquired Blade helicopter operation, not Joby's own air taxis, so traditional valuation multiples are not very meaningful. At a market cap near $9 billion against minimal core revenue, the stock prices in a commercial future that still depends on FAA certification and scale.

Headline figures (approximate, 2026-06-27): ACHR shows liquidity (cash, equivalents & short-term investments) ~$1.78B (Q1 2026), revenue ~$1.6M (Q1 2026), effectively pre-revenue, net loss ~$217.7M (Q1 2026), operating cash used ~$149M (Q1 2026); JOBY shows cash & short-term investments ~$2.5 billion (Q1 2026), revenue (q1 2026) ~$24 million (mostly acquired Blade passenger business, not eVTOL), fy2026 revenue guidance ~$105 to $115 million, net loss (q1 2026) ~$110 million.

ACHR and JOBY are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
