Archer Aviation vs. Joby Aviation: Which eVTOL Upstart Is a Better Stock in 2026?

The article pits eVTOL peers Archer Aviation (ACHR) vs Joby Aviation (JOBY) as U.S. eVTOL testing frameworks advance, but both remain loss-making and certification-dependent. Archer reported FY2025 net loss of $618.2M with free cash flow of -$511.7M, while Joby’s FY2025 revenue rose to ~$53.4M (from ~$136k in 2024) yet net loss widened to ~$930M and free cash flow was -$563.8M. Valuation contrasts show P/S of ~1,680x for Archer vs ~96.7x for Joby, with the author favoring Joby for 2026 despite continuing FAA/patent-and-trade-secret litigation risks for both.

Analysis

The market is still pricing these names like pre-commercial venture equity, so the key driver is not near-term unit economics but who can survive long enough to own certification optionality. On that score, the likely winners are the industrial enablers and strategic partners with capped downside — STLA and TM — while the losers are the highest-duration common equities that need repeated raises before first meaningful production. ACHR looks more fragile because it has a weaker liquidity cushion and a more concentrated commercial path, which raises the probability of equity dilution before revenue scales.

Second-order effects matter more than the headline comparison: if regulators stay on schedule, the first monetization likely comes from premium airport shuttle and government/cargo adjacencies, not mass urban commuting. That favors DAL and UAL as route-partner narratives, but only modestly; their upside is reputational/option value, not P&L accretion over the next 1-3 quarters. UBER may get a small strategic halo from Blade-style integration, though any economics are likely de minimis versus its core mobility take rate.

The contrarian miss is that valuation screens are close to meaningless here because both revenue bases are too small to anchor multiples; the real variable is financing path and milestone cadence. Any delay in FAA progress, a stumble in flight-test safety, or litigation overhang turning into a cash drain would quickly re-rate both names lower, with ACHR more exposed to that outcome. Over 6-18 months, the stock that can de-risk manufacturing without issuing stock at a punitive price should outperform, but until then this is a liquidity-and-catalyst trade, not a fundamentals trade.

Key Decisions for Investors

• Relative-value: long JOBY / short ACHR on a 3-6 month horizon. Thesis is not that JOBY is cheap, but that it has better survivability and a clearer path to milestone financing; cover the short if ACHR closes the balance-sheet gap or secures non-dilutive capital.
• Avoid outright long exposure in both names ahead of certification/newsflow unless sized as venture-style optionality. The risk/reward is poor because downside from dilution or delay can be 30-50% on a single missed milestone, while upside is likely capped until commercial schedules are validated.
• Watch STLA and TM as lower-beta ways to express eVTOL manufacturing optionality. A small long in STLA vs a basket of high-duration EV/air-mobility names can capture partnership upside with far less binary risk.
• For event-driven traders, use call spreads only after independently verifiable FAA or production-milestone catalysts, not on press-release language. Best entry is on post-news weakness; stop if the company misses the next certification or funding checkpoint.
• Set an alert on ACHR financing terms and share count expansion. If dilution accelerates faster than revenue or firm aircraft orders, the stock should be treated as a financing short rather than a technology long.
