JOBY vs XTIA: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 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. JOBY and XTIA 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 JOBY and XTIA 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.

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.

XTI Aerospace, Inc. (NASDAQ: XTIA) was formed in March 2024 when XTI Aircraft Company completed a reverse merger with Inpixon, a real-time-location-systems (RTLS) and industrial-IoT company; the combined business adopted the XTI Aerospace name. For years its defining project was the TriFan 600, a six-seat vertical-takeoff-and-landing (VTOL) business aircraft designed to take off like a helicopter and cruise like a fixed-wing jet, marketed with a large book of conditional, non-binding pre-orders. In February 2026 the company announced it was shelving the TriFan 600 program, putting it on what management described as a cost diet and strategic review, and redirecting its aircraft engineering base into an Autonomous Defense Systems division pursuing drone and unmanned-platform opportunities.

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

• JOBY drivers: Lead in FAA certification; Strategic backers and balance sheet.
• XTIA drivers: Drone distribution is now the revenue engine; Autonomous defense and unmanned systems pivot.

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: 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. For XTIA, xTIA is a highly speculative micro-cap with a long record of net losses and negative cash flow.

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 JOBY if you believe its drivers more; XTIA 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 JOBY and XTIA guides.

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.

XTIA. These figures are highly speculative and change quickly for a name like XTIA. Much of the reported revenue comes from the recently acquired drone-distribution business rather than the aircraft, the company is still loss-making, and the share count and price have been reshaped by repeated offerings and a large reverse split. Always confirm the latest figures against XTI's most recent SEC filings before acting on anything here.

Headline figures (approximate, 2026-05-06): 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; XTIA shows revenue (fy2025 pro forma) ~$121.6M, driven by the Drone Nerds distribution business, 2026 revenue target ~$160M+ (management guidance, ~30% growth, not assured), net loss from continuing operations (fy2025) ~$39.0M, market cap ~$70M to $82M (small-cap; varies with the volatile share price).

JOBY and XTIA 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.
