Archer Aviation has reached a landmark agreement to acquire its former rival, Wisk Aero, alongside two other subsidiaries from aerospace giant Boeing. Under the terms of the transaction, Boeing will transfer ownership of Wisk Aero, digital airspace management firm SkyGrid, and drone manufacturer Insitu to Archer. In return, Boeing will secure a significant equity stake in Archer, receiving newly issued shares that represent approximately 16.5% of the company post-transaction.

This acquisition marks a dramatic shift in the relationship between the two electric vertical takeoff and landing (eVTOL) pioneers. In 2021, Wisk filed a high-profile lawsuit against Archer alleging intellectual property theft, prompting a $1 billion countersuit from Archer. The bitter legal battle concluded in a surprise settlement that transformed the rivals into collaborators, establishing Wisk as Archer’s exclusive autonomous technology provider. Wisk itself originated from Kittyhawk, an early electric aviation startup backed by Google co-founder Larry Page, before becoming a joint venture and eventually a fully owned subsidiary of Boeing.

The consolidation comes as Archer rapidly expands its footprint beyond commercial air taxis. The California-based company recently launched Archer Defense, securing hundreds of millions in funding from major institutional investors like BlackRock and Wellington, and partnering with defense contractor Anduril to develop hybrid-powered military aircraft. Meanwhile, Archer continues to advance its flagship all-electric Midnight aircraft, recently completing a successful piloted round-trip flight in California as it prepares for upcoming operations under the federal eVTOL Integration Pilot Program.

Key Takeaways

• Archer Aviation is acquiring Wisk Aero, SkyGrid, and Insitu from Boeing in exchange for an approximate 16.5% equity stake in Archer.
• The acquisition resolves years of intense rivalry and legal disputes between Archer and Wisk, which began with a 2021 trade secret lawsuit.
• Archer continues to diversify its portfolio, expanding into defense applications and advancing its Midnight eVTOL aircraft toward commercial operations.

Editor’s Analysis & Impact

The acquisition of Wisk Aero by Archer Aviation represents a massive consolidation wave in the nascent eVTOL and advanced air mobility (AAM) sectors. By absorbing Wisk, SkyGrid, and Insitu, Archer not only neutralizes a major competitor but also integrates critical autonomous flight and airspace management technologies directly into its ecosystem. Boeing’s transition from Wisk’s sole owner to a major shareholder in Archer signals a strategic pivot; rather than funding a proprietary air taxi program, the aerospace giant is betting on Archer’s diversified commercial and defense-oriented platform. This deal, combined with Archer’s recent capital raises and defense partnerships, positions the company as a dominant force capable of navigating both the regulatory hurdles of commercial urban air mobility and the lucrative demands of military logistics.
