The flight taxi manufacturer Archer Aviation can complete the acquisition of three Boeing divisions: The US antitrust review ended on September 18, 2026, without objections. Archer thus receives Wisk Aero, SkyGrid, and Insitu for about 19.75 percent of its shares. The three companies together bring nearly two million flight hours and more than 200 million dollars in annual revenue.
Deal combines autonomy technology with Archer’s flying taxis
Archer and Boeing signed the purchase agreement on August 9, 2026. Wisk Aero develops autonomous, pilotless flying taxis, bringing Archer its own autonomy technology in-house. SkyGrid operates a platform for digital airspace management that coordinates autonomous flights and integrates with air traffic. Insitu builds unmanned aircraft, including the reconnaissance drone ScanEagle, primarily for military customers in 35 countries.
Archer pays for the purchase entirely in shares: Boeing receives about 19.75 percent of Archer’s common stock as well as two warrants, with no cash involved. Archer aims to combine the three companies into a “physical AI platform” for aviation and defense. This refers to systems that not only process text or images but also autonomously control real aircraft and drones. Their autonomy technology is expected to flow into Archer’s AI foundation model ZEE. Together, Wisk, SkyGrid, and Insitu bring nearly two million flight hours and a defense business that, according to Archer, generates more than 200 million dollars in annual revenue. Industry observers place the term “physical AI” within a broader trend recently shaped by chip manufacturers like Nvidia for robots and autonomous vehicles.
Antitrust clearance brings completion closer
The waiting period required by the Hart-Scott-Rodino Act for corporate acquisitions expired on September 18, 2026, at 11:59 PM Eastern Time without objection from US antitrust authorities. The law requires larger acquisitions in the US to undergo a routine review before they can be completed. Archer confirmed the expiration in a statement to the stock exchange regulator on September 24, 2026. The clearance fulfills a central closing condition, while further industry-standard conditions and regulatory approvals are still pending, according to the company. Archer expects final closing by the end of 2026.
Following the initial announcement in August, Archer’s stock reportedly rose by more than 21 percent in pre-market trading, an assertion that has not been independently verified. Boeing remains not only a seller in the deal: the aircraft manufacturer is investing in Archer shares in return and has agreed to a technology cooperation. Boeing retains access to Wisk’s autonomy technology for its own civil and military aircraft. On the platform Stocktwits, investor sentiment toward Archer remained predominantly optimistic after the news, while it soured for Boeing’s stock according to analyses from several financial portals.
Former rivals become partners
For Boeing, the sale marks a withdrawal from business areas outside its core business of commercial aircraft and defense projects. Wisk emerged in 2019 from a joint project between Boeing and Larry Page’s startup Kitty Hawk and was later fully acquired by Boeing. Unusually, Wisk had sued Archer in 2021 for alleged theft of trade secrets and patent infringement. The parties reached an out-of-court settlement in 2023, at which point Boeing had already invested in Archer, and Wisk became the exclusive autonomy supplier for future Archer aircraft. Kitty Hawk itself ceased flight operations in 2022 and no longer exists as an independent company.
The deal also fits into a series of stock deals through which AI-related companies are growing this year. In August, SpaceX completed the acquisition of the coding tool Cursor for 60 billion dollars in its own shares. Archer is not alone in financing defense technology: at the same time, the Pentagon is negotiating a billion-dollar loan for the AI cloud provider Fluidstack.
It will be crucial whether Archer can operationally integrate the three newly acquired divisions while its own flying taxi Midnight is set to launch into commercial passenger service. By the planned completion at the end of 2026, it must also become clear how the company will reconcile its civil ambitions with the growing defense business of the new divisions.
