AST SpaceMobile and Archer Aviation both represent bold, capital-intensive bets on transformative infrastructure, but only one earns the stronger buy recommendation for 2026.
Archer Aviation is pushing toward commercialization of its electric vertical takeoff and landing aircraft, backed by major aerospace and automotive partners providing critical manufacturing and financial support.
The company’s growth strategy is anchored by a United Purchase Agreement providing for the conditional purchase of up to $1.0 billion in Midnight aircraft from United Airlines Holdings.
Archer has also secured partnerships with the U.S. Air Force and Stellantis, giving the company both military credibility and serious manufacturing infrastructure as it scales toward commercial operations.
The company focuses on so-called flying taxis designed to bypass ground traffic congestion, a concept that has attracted significant investor attention as urban mobility solutions gain traction globally.
AST SpaceMobile, meanwhile, is building a space-based cellular broadband network designed to eliminate global dead zones by connecting directly to existing smartphones without specialized hardware.
The company has assembled an impressive roster of strategic partners and investors, including AT&T, Verizon, Vodafone, Alphabet, American Tower, and Rakuten, among several other major telecom operators worldwide.
That constellation of telecom backers gives AST SpaceMobile a fairly high competitive moat, making it significantly harder for rival companies to replicate its space-based network infrastructure at scale.
On valuation, Archer Aviation looks more affordable than AST SpaceMobile based on forward price-to-earnings estimates, though Archer carries a higher price-to-sales ratio than its space-based competitor.
AST SpaceMobile does carry the burden of very high capital expenditures right now, a reflection of the enormous cost involved in deploying a functional satellite network across global coverage zones.
Regulatory frameworks for eVTOL aircraft are taking shape in the United States and several international markets, which gives Archer credit for meaningful progress as it pursues early revenue through military and cargo applications.
Despite those advances, AST SpaceMobile’s quick path to revenue growth and its roster of telco investors make it the stock to buy in 2026, according to the analysis.
