Five years ago, electric air taxis sounded like science fiction. Today, Archer Aviation’s full-scale aircraft is flying higher and faster, its manufacturing plant in Georgia is built, and big-name partners like United Airlines and Stellantis are pushing it toward service. The disconnect is this, the tech and partnerships feel tangible, yet the stock still trades like a young, risky story. That gap is where opportunity often hides.

This piece builds a current, sober narrative from official filings, reputable reporting, and regulatory updates. We will look at Archer’s progress, the competitive board, and where the market could be mispricing risk. Then we stack it against three direct peers using today’s market metrics.

Archer, right now: execution milestones that actually matter

FAA certificates and flight testing. Archer secured its Part 135 Air Carrier and Operator Certificate in June 2024, which allows the company to operate commercially with conventional aircraft while it builds procedures for Midnight, its eVTOL, ahead of type certification. Independent coverage from Reuters confirms the milestone and puts it in context as only the second eVTOL developer to reach that level at the time. investors.archer.com+1

In 2025 Archer stepped into piloted test flights and began expanding the envelope. In September 2025, the company reported its highest-altitude flight to date at 7,000 feet, after earlier long-range demos, and highlighted speeds above 120 mph in testing. These are the kinds of incremental, verifiable proofs regulators look for as type certification approaches. Coverage from Live Science mirrors the altitude milestone and recent performance numbers. investors.archer.com+2investors.archer.com+2

Factory and scaling plan. Archer finished construction of its high-volume ARC facility in Covington, Georgia and secured a certificate of occupancy, with initial production tooling loaded in. The company’s guidance has targeted initial builds in 2025, supported by Stellantis’ manufacturing partnership. Third-party trade press and the company’s own releases align on these facts. investors.archer.com+2investors.archer.com+2

Defense and near-term revenue options. Archer delivered its first Midnight to the U.S. Air Force in August 2024 under an AFWERX Agility Prime contract of up to $142 million, with additional deliveries planned. Defense work does not replace commercial service, but it offers data, credibility, and some revenue ahead of consumer launches. investors.archer.com+2Aviation International News+2

Routes and launch venues. United and Archer previously named Chicago O’Hare to Vertiport Chicago as an initial route, then expanded plans to New York City airport connectors in 2025 updates. Archer has also been tied to the LA28 Olympics use case to move fans and VIPs between venues, a high-visibility proving ground if schedules hold. investors.archer.com+2The Verge+2

Regulatory backdrop, finally clearer. The FAA’s powered-lift framework, including advisory material in 2025, gives developers a more predictable certification path. AIN Online and Flying Magazine both covered the new guidance, and named Archer among the frontrunners that had already firmed up certification bases with the agency. Aviation International News+1

Bottom line on progress: The ingredients investors wanted to see, pilot-in-command flights, a real factory, defense validation, airport-to-city route planning with a major airline, and a maturing FAA rule set, are now present.

The valuation question: where the market might be discounting too much

Stocks price two things; execution and oxygen. Execution shows up in test cards, certificates, and customer traction. Oxygen shows up as cash runway.

Cash and runway. Archer’s 2025 investor updates and coverage suggest liquidity around the billion-dollar mark earlier this year, with Stellantis support and later fundraising noted by outlets like Seeking Alpha. Even if you haircut headline figures, Archer’s cash plus partner commitments has been repeatedly cited as strong relative to peers, and consistent commentary has modeled quarterly burn near $100 million as they ramp. The runway is not infinite, it never is at this stage, but it is measurable and longer than many competitors enjoy. investors.archer.com+1

De-risking the launch narrative. The single largest risk in eVTOL is certification. The second is industrialization at cost. Archer has real movement on both, and a credible airline route partner in United that is leaning in across multiple cities. As the FAA powered-lift guidance firmed up in mid-to-late 2025, the market’s structural uncertainty declined. That should compress the discount rate investors are applying to the revenue ramp that follows certification. Aviation International News+1

Use-case realism. Archer is not promising globe-spanning missions. Midnight is designed for 10 to 20 minute hops, city to airport, or between key nodes. These are high-value, repeatable lanes that plug into existing airline networks. When early services are bundled into a United itinerary, demand discovery and pricing power improve, and that matters for unit economics. Reuters, The Verge, and United’s original Chicago announcement help triangulate the realism of this plan versus hype. Reuters+2The Verge+2

Why the market might still be skeptical. The stock can trade with daily volatility around news on certification pace, macro risk, or sector sentiment. On days like today, ACHR can sell off hard on headlines or risk-off flows. That does not change the core catalysts, it just sets up better entries for investors who are underwriting the 24- to 36-month path. FinancialContent

Our take, in one line: If Archer holds its cadence on test milestones, keeps the factory on schedule, and locks the first operating venues with United, the stock today looks early rather than expensive.

The competitive board: three or four that actually matter

Joby Aviation (JOBY). Joby is the other U.S. leader with deep funding, a head start on certification steps, and strong ops chops. The company recently highlighted progress in Stage 4 of 5 in the FAA type certification process and completed a first airport-to-airport flight in controlled airspace in California. Expect New York and Los Angeles to be early markets. For investors, Joby is the benchmark that helps set the multiple for Archer if both clear certification. Joby Aviation+1

Eve Air Mobility (EVEX). Backed by Embraer, Eve benefits from airline-grade industrial DNA and global customer letters of intent. Brazil’s ANAC has publicly discussed a 2026–2027 certification window as realistic. Eve’s strategy of leveraging Embraer’s services network and airport relationships could shine once certification is locked, though timelines and capital needs remain watch points. Reuters

Archer Aviation (ACHR). Archer’s differentiation is an airline-first go-to-market with United, a Stellantis-backed plant in the U.S., and early defense traction with the Air Force. The last 18 months tightened the story, from Part 135, to piloted flights, to facility completion. Reuters+2investors.archer.com+2

What about Lilium and others? Lilium’s insolvency episodes in late 2024 and early 2025 are a cautionary tale on capital intensity and certification complexity. It shows why liquidity and credible partners matter, and why the market may reward Archer and Joby with relative premium if they keep executing. The Verge+1

Where Archer could surprise the market

1. Event-driven visibility. A high-profile operations debut, like LA28 Olympic transport, would be a powerful proof point that pulls forward public acceptance and regulatory confidence. AP News
2. Defense bridge revenue. Additional AFWERX task orders or adjacent defense work keeps pilots current, pays for testing hours, and stretches the runway. investors.archer.com
3. Airport network lock-in with United. As United integrates eVTOL bookings and ground logistics for Chicago and New York, the flywheel between airline schedules, vertiport access, and eVTOL utilization can turn faster than models assume. investors.archer.com+1
4. Manufacturing rhythm. The first year of production is about repeatability. If ARC in Georgia proves it can build, test, and deliver aircraft on a predictable cadence with Stellantis processes, margins and learning curves improve. investors.archer.com

Risks worth stating out loud

• Certification timing slip. Even with clearer FAA guidance, novel aircraft can hit unexpected requirements, which pushes revenue out. flyingmag.com
• Capital raises. A multiyear ramp can require more cash, especially if the company accelerates fleet builds or infrastructure. Coverage has cited quarterly burn near nine figures. Seeking Alpha
• Public acceptance and infrastructure. Vertiport permitting, community noise comfort, and integration with airport security all matter. Archer’s sub-70 dB goal helps, but local acceptance is earned flight by flight. (Regulatory context and powered-lift guidance help, but they do not replace community process.) Aviation International News

So, is Archer undervalued?

On fundamentals, Archer is less speculative today than it was a year ago. The company moved several binary items to “de-risked,” including Part 135, a finished plant, piloted flights, and a maturing FAA playbook for powered-lift. It also has airline and auto OEM partners whose incentives are aligned with getting aircraft into service. If you believe certification in the 2026 zone is achievable, and that United-anchored airport shuttles can operate at useful load factors, Archer’s valuation begins to look more like a pre-revenue industrial with line of sight to operations, and less like a moonshot. That is the profile where multiple expansion often happens as the market stops discounting everything.

The market scoreboard, today’s snapshot

Below are the three eVTOL developers we see as the most relevant public comps right now, with current price snapshots. Use this as a market context lens, not investment advice.

The segment’s top companies to watch, and why

• Archer Aviation, because it is pairing airline distribution with a focused route map, a domestic factory, and active defense customers. investors.archer.com+3investors.archer.com+3investors.archer.com+3
• Joby Aviation, because it is pacing sector certification steps and demonstrating operational flights between public airports in FAA airspace. Joby Aviation+1
• Eve Air Mobility, because Embraer’s ecosystem offers maintenance, training, and airport relationships that can shorten the service ramp once the aircraft is certified by ANAC and validated globally. Reuters
• Beta Technologies is private, yet it remains one of the technical leaders that regulators cite alongside Archer and Joby when discussing frontrunners, which shapes overall sector credibility. Aviation International News

Final word

Archer does not need to win every city to create value. It needs to certify Midnight, prove reliable service on a small set of profitable airport shuttles, and rinse and repeat. The last year pulled several key levers in that direction. Markets sometimes lag that reality until the first ticketed passengers start posting videos from the cabin. If Archer keeps hitting test and factory milestones, and United keeps building the airport links, today’s price looks more like an early entry than a late chase.
