Joby closed at $10.35 on 20,175,722 shares, Archer closed at $5.92 on 57,973,421 shares, and EHang closed at $9.32 on 852,869 shares, but the price action hid a wider split in how the market is valuing certification evidence, capital-structure pressure, and reporting credibility across the eVTOL group. My view is that 2026 positioning is no longer about who has the best story; it is increasingly about who has the cleanest proof stack. That split is becoming materially harder for investors to ignore across the group.
For today’s detailed market data, see Joby Daily, Archer Daily, and EHang Daily.
Is Joby’s certification momentum strong enough to offset Paul Sciarra’s new sale overhang?
The tape suggests investors think the answer is yes, but I think that confidence is a little too relaxed. As the Joby Daily noted, Paul Sciarra still beneficially owns 56,520,980 shares, or 5.7% of the company, which makes the latest 10b5-1 plan easy to frame as ordinary liquidity management rather than a change in conviction. That framing explains why JOBY held $10.35 even after the market learned a new trading plan could permit sales of up to 1,875,000 shares while an earlier plan covering up to 1,500,000 shares remains active through June 30, 2026. On disclosed capacity alone, that is 3,375,000 shares of potential supply against the day’s 20,175,722-share volume, which is large enough to matter even if the stock does not feel it all at once.
My read is cautious rather than outright bearish because the operational backdrop is real. Joby said on March 11 that its first FAA-conforming aircraft, N547JX, had already begun flight testing for Type Inspection Authorization, and the company described that aircraft as the first of a fleet currently in production for TIA support (Joby press release, March 11). That matters because a market that sees tangible certification conversion is usually more willing to absorb insider supply than one still buying only a future promise. Joby reinforced that point again in its first-quarter 2026 shareholder update, where it said it had completed the SR3 audit, was producing parts for eight additional conforming aircraft, and had pushed composites production to more than 2.5 times last year’s volume while expanding capacity to nearly 1.5 million square feet (Joby Q1 2026 results).
Still, the way I see it, investors are making a subtle mistake if they treat “he still owns 5.7%” as the whole signal. Ownership retention tells you Sciarra is not exiting the story, but the programmed-sale capacity tells you the market may have to finance incremental supply during a period when valuation support remains milestone-sensitive. There is also a positioning issue here: when a company is being valued on the expectation of future FAA conversion, any repeated stock-sale headline can create small but cumulative hesitation among marginal buyers who otherwise would have paid up for the next catalyst. If Joby keeps converting FAA progress into visible hardware and “for credit” testing, the overhang can stay secondary. If that cadence slows, the sale plan can become a headline risk quickly because the market will no longer have fresh execution evidence to overpower the supply narrative. Macro data (10Y yield, fed funds) was unavailable this run. Net-net, I lean mildly cautious on the stock reaction: the filing did not invalidate Joby’s lead, but the market looks too willing to discount the overhang simply because the certification story is currently strong.
Has the 2026 U.S. certification race already tilted meaningfully toward Joby over Archer?
I think it has, and the key reason is not rhetoric but sequence. Archer has real momentum: its first-quarter 2026 update said it became the first eVTOL company to close Phase 3 of the FAA’s four-phase type-certification process, had entered Phase 4, and still expected initial U.S. operations in 2026 under the White House-backed eVTOL Integration Pilot Program (Archer Q1 2026 results). That is meaningful progress, and I do not think the market should dismiss it. But the market also should not pretend that Phase 4 language is the same thing as having already put an FAA-conforming aircraft into the air.
That is where the gap now shows up. The source file’s Archer discussion explicitly frames the company as still waiting for its conforming-aircraft moment, while Joby had already flown N547JX in March and said additional conforming aircraft for TIA support were in build. The Archer Daily also highlighted the harder financial side of the story: just $1.6 million of revenue, a $217.7 million net loss, and second-quarter adjusted EBITDA guidance of negative $170 million to negative $200 million. Against that backdrop, Archer’s 57,973,421-share volume looks less like clean certification confidence and more like a market still debating whether capital access and timeline promises can bridge a real execution gap. By contrast, Joby’s evidence stack now includes conforming-aircraft flight, SR3 completion, and scaling manufacturing support for the remaining TIA fleet.
My view is constructive on Joby’s relative position and cautious on Archer’s need to compress time. Archer is not out of the race; it still had roughly $1.78 billion including short-term investments in the raw daily file, and that balance sheet gives it time to keep pushing through Phase 4. But time is not the same as proof. The company still needs a visible conforming-aircraft milestone to narrow what now looks like a real public certification hierarchy. Archer’s bull case is that its eIPP positioning, LA28 visibility, and high trading liquidity can keep investors engaged long enough for the technical evidence to arrive. I understand that argument, but it remains a financing-and-expectation bridge until the hardware proof catches up. The way I see it, the 2026 U.S. launch debate has already shifted from “who could win?” to “can Archer produce hard evidence quickly enough to keep Joby from becoming the default first-choice U.S. eVTOL name?” Today, the data supports a constructive lean on Joby’s lead and a cautious lean on Archer’s catch-up burden.
Is EHang’s unmatched pilotless certification record still being discounted because financial trust weakened?
Yes, and I think that discount is rational even if it is frustrating for bulls. Operationally, EHang still owns one of the strongest certification resumes in the sector. The source file notes that the EH216-S has obtained the world’s first type certificate, production certificate, standard airworthiness certificate, and commercial Air Operator Certificates for pilotless human-carrying eVTOL service. In most emerging-aviation narratives, that should command a premium. Yet the EHang Daily paired that operational advantage with a less supportive sponsorship picture: 35 institutions added shares in the latest quarter while 48 reduced positions, suggesting the market is not uniformly willing to pay up for certification leadership alone.
The reason is credibility friction. In its May 2026 Form 6-K/A, EHang said it was amending prior reports by providing corrected unaudited interim financial information for the second, third, and fourth quarters and the full fiscal year ended December 31, 2025. The filing says the company discovered errors in revenue recognition and made corresponding corrections across revenues, accounts receivable, contract liabilities, accrued expenses, tax-related accounts, and other line items, while also warning investors not to rely on the previously furnished 6-K information. That combination matters because it moves the conversation from simple quarter-to-quarter volatility to process reliability, and process reliability is exactly what long-duration aviation investors usually pay up for. My read is cautious because that kind of correction does not erase the aircraft story, but it does raise the discount rate investors apply to it. Institutions can accept technology risk; they are much less forgiving when reporting reliability becomes part of the underwriting burden.
The market action fits that interpretation. EH traded only 852,869 shares on the day, a fraction of Joby’s and Archer’s liquidity, which means credibility shocks have less natural sponsorship to absorb them. Lower liquidity does not invalidate the business, but it does raise the odds that a governance question translates into a valuation penalty faster and lasts longer. The way I see it, the market is separating regulatory leadership from investable trust: EHang can be ahead in pilotless certification and still trade at a valuation haircut if investors believe governance monitoring just became harder. That is why I lean skeptical on near-term multiple expansion even while staying constructive on the operational milestone stack. Until EHang rebuilds confidence with cleaner disclosure continuity and steadier institutional support, its certification premium is likely to remain partially discounted rather than fully capitalized.
What to Watch Tomorrow
- First, watch whether Joby follows the insider-sale filing with another FAA or TIA-related proof point that keeps supply-overhang concerns in the background.
- Second, watch whether Archer produces any concrete conforming-aircraft or Phase 4 execution evidence instead of extending the market’s reliance on timeline guidance.
- Third, watch whether EHang shifts investor focus back toward operating traction and certification monetization rather than corrected historical financials.
