THE PHYSICAL AI DISPATCH
Archer absorbs Wisk, Insitu & SkyGrid. Joby answers with a $500M defense buy. Here's what it means for the next $100B company.
Executive Summary
In a single 24-hour window this month, the eVTOL industry's two market leaders redefined what they're actually building. Archer Aviation signed a deal to acquire three Boeing subsidiaries — Wisk Aero, Insitu, and SkyGrid — making Boeing its largest outside shareholder in the process. One day later, Joby Aviation answered with a $500M acquisition of Resonant Sciences, a profitable Dayton, Ohio defense contractor specializing in stealth and sensing technology.
Neither company previously held a prime-scale defense position. Both do now. And neither deal is really about air taxis — they're about who controls the full autonomy stack: flight software, sensors, manufacturing, and now, government revenue.
This edition breaks down both deals, maps the strategic capital already surrounding each company, and asks the question investors are actually pricing in: who gets to $100B first?
1. Archer Aviation: The Boeing Consolidation
Archer and Boeing signed definitive agreements on August 10, 2026, under which Archer acquires Boeing's Wisk Aero, Insitu, and SkyGrid subsidiaries in an all-stock transaction.
Boeing becomes Archer's largest outside shareholder, with a resulting stake reported at nearly 20%, delivered through newly issued Class A shares and warrants
Boeing separately commits up to $55M into an upcoming Archer funding round, plus warrants to purchase up to $200M more in Archer stock over time
A cross-licensing arrangement lets Boeing retain rights to Wisk's autonomous flight technology for its own commercial and defense platforms — a detail worth watching given ongoing speculation about Boeing's eventual 737 successor
The deal is subject to Hart-Scott-Rodino antitrust review before closing
What Archer actually gets:
Wisk Aero — six generations of autonomous eVTOL design, 1,700+ completed test flights, proprietary flight control computers
Insitu — a Navy-deployed ISR drone manufacturer with 3,500+ UAS fielded across 35 countries and more than $200M in annual defense revenue — a profitable business on day one, not an integration bet
SkyGrid — ground-based, aircraft-agnostic airspace intelligence and traffic-management software
Combined: nearly 2 million flight hours flowing into Archer's ZEE foundation model, positioning Archer as an end-to-end physical AI platform across commercial aerospace, defense, and air traffic management
Combined: nearly 2 million flight hours flowing into Archer's ZEE foundation model, positioning Archer as an end-to-end physical AI platform across commercial aerospace, defense, and air traffic management
2. Joby Aviation: The Resonant Sciences Answer
One day later, on August 11, 2026, Joby announced a definitive agreement to acquire Resonant Sciences, a Dayton/Beavercreek, Ohio defense technology company, for approximately $500M — $450M in cash and $50M in stock. The deal is expected to close in the first half of 2027, pending regulatory approval.
What Joby gets:
Advanced RF sensing, electronic warfare, and low-observability/stealth design technology, integrated across 20+ military airframes
Roughly 250 Dayton-area employees, more than 90% of whom hold security clearances
A combined manufacturing, integration, and testing footprint of nearly 1 million square feet in the Dayton region once merged with Joby's existing 768,000-square-foot facilities
An already profitable business — Resonant reports $100M in trailing-12-month revenue and active classified U.S. government programs
Resonant becomes Joby's dedicated defense division under founder/CEO J. Micah North, absorbing Joby's existing dual-use programs — including its turbine-electric and hydrogen-electric hybrid aircraft work with L3Harris — while Joby's core commercial organization stays focused on certifying and scaling its electric air taxi.

4. Boeing Becomes a Player — And Joby's Bench Runs Just as Deep
The headline here isn't just that Boeing bought into Archer — it's that both companies have spent years quietly assembling strategic capital tables that read like an industrial who's-who. Boeing joining Archer's cap table is the biggest single logo, but it's an addition to an already crowded field, not a first mover.
Archer's strategic bench:
Stellantis — Archer's longest-standing strategic partner (since 2020), with a manufacturing agreement worth up to ~$400M to scale production of Archer's Midnight aircraft to 650 units annually, plus direct equity investment
United Airlines — long-term strategic investor and launch customer, with a purchase agreement for up to 1,500 aircraft (including warrants) alongside its equity stake
Boeing — now Archer's largest outside shareholder (~20%) following the Wisk/Insitu/SkyGrid deal, plus direct capital and warrant commitments
ARK Invest and other institutional investors have also participated in recent funding rounds
Aggregate funding to date: north of $1.5B raised prior to the Boeing transaction
Joby's strategic bench:
Toyota — Joby's largest strategic backer by a wide margin, with total investment now at $894M and a 51%-owned manufacturing joint venture (announced June 2026) giving Toyota exclusive rights to build Joby's S4 aircraft and three of five board seats
Delta Air Lines — $60M initial investment (2% stake), scalable to $200M on milestone achievement, tied to a home-to-airport service partnership launching in New York and Los Angeles
SK Telecom — $100M equity investment tied to Korea's K-UAM Grand Challenge and a broader mobility partnership including TMAP, South Korea's largest mobility platform
Uber — an early backer since Joby's Series C, having also sold its Uber Elevate air-taxi unit to Joby
Additional backers include All Nippon Airways, JetBlue (an investor since 2017), and Baillie Gifford
Aggregate funding raised: more than $2B to date
The read for investors: Archer's strategic capital has concentrated around manufacturing and airline distribution (Stellantis, United, now Boeing).
Joby's has concentrated around global market access and consumer-facing distribution (Toyota, Delta, SK Telecom, Uber, ANA).
The Boeing deal doesn't hand Archer a strategic-investor advantage Joby lacks — it hands Archer something Joby doesn't yet have at this scale: an in-house, revenue-generating defense and ISR business.
Whether Joby's Resonant acquisition closes that specific gap by mid-2027 is the variable to watch.5. Who Gets to $100B First?
Rather than call a winner, it's worth laying out what each company is actually underwriting:
Archer's case — breadth. It now owns an end-to-end stack: airframe, autonomy, ISR hardware, and traffic-management software, plus a strategic anchor in Boeing that opens doors to primes and DoD relationships Archer couldn't access alone.
Joby's case — speed and margin. Resonant is profitable and cash-generative today, not a multi-year integration project. Joby buys a functioning revenue engine while keeping its commercial air-taxi roadmap uncontaminated by defense-program complexity.
The swing variable: FAA certification pace versus defense-budget cycle timing. Whichever revenue line scales faster over the next 18 months likely determines who re-rates first.
Which thesis are you underwriting — platform breadth, or capital-efficient defense revenue? Both are legitimate paths to a $100B outcome; they just get there on different timelines with different risk profiles.6. Why This Matters Beyond eVTOL
For founders: Primes and legacy aerospace are actively divesting non-core autonomy and sensor assets. That's a sourcing signal — for talent, for IP licensing conversations, and for spin-out opportunities from within Wisk, Insitu, SkyGrid, and Resonant as integration proceeds.
For investors: Defense revenue is fast becoming the credibility proof point that earns a premium multiple. Pure civilian air-mobility stories are losing ground to dual-use stories with government revenue attached — a trend worth underwriting into diligence on any growth-stage aerospace or autonomy company, not just the two named here.
Talent to watch: Integration windows are historically when the best people leave to build something new. Early movement out of Wisk, Insitu, SkyGrid, or Resonant over the next two quarters is worth tracking as an early-stage deal-sourcing signal.
7. Under-the-Radar Signal
With two of the largest independent eVTOL/UAS assets now absorbed into Archer and Joby, the field of credible standalone acquisition targets or partners for the next prime looking to move — Lockheed, RTX, L3Harris, Anduril — has narrowed considerably. Mid-tier players worth watching for the next move: Vertical Aerospace, BETA Technologies, Overland AI, and BRINC.

Closing Insight
The eVTOL industry didn't wait for FAA certification to define its next chapter — it went and bought one instead. Boeing, once a competitor building its own autonomous flight programs, is now a shareholder betting on someone else's platform to get there first.
