Amazon's Leo network and Globalstar's spectrum could be the most underpriced option inside its stock if the Starlink rival works. While attention focuses on AWS capex, Amazon is building Leo; StockSavvyShay says initial service is on track for year-end and the Globalstar acquisition is planned. x.com 

AST SpaceMobile faces growing satellite-cellular competition beyond Starlink Mobile, which, per Starlink, agreed to acquire a nationwide US low-band spectrum portfolio. A later 5,105-satellite direct-to-cell system from Amazon tied to Globalstar is also a threat. AST's best chance is giving AT&T, Verizon and T-Mobile a fighting chance against them; that reliable Starlink Mobile service is a long way off doesn't matter. x.com  x.com  x.com  x.com 

AST SpaceMobile's direct-to-phone satellite network makes it an extremely bullish long-term space-economy bet. Partnerships with more than 60 mobile operators representing over 3 billion potential subscribers and about $1.3 billion in contracted revenue backlog support the case. It targets initial, intermittent broadband coverage in five countries before end-2026; its market cap is roughly half Rocket Lab's, though both face significant execution risks. x.com 

AST SpaceMobile's D2D prospects weaken as telcos look to Amazon and Ligado may give up spectrum. Telcos see Amazon as their most realistic potential savior, though their JV seems poised to sign MOUs with both. People consulted expect Amazon to buy Viasat mainly for international spectrum; US capacity and timing remain uncertain. AST's payments do not cover Ligado's Viasat dues, so Ligado may settle with the US for auction credits and surrender spectrum rights, leaving AST stranded. x.com 

SpaceX and Amazon's unlimited resources and talent make AST SpaceMobile an unwise investment. Buying it means competing with both. x.com 

Anti-SpaceX demand could bring AST SpaceMobile and Amazon a lot of business. If Avery Sullivan's interpretation of AST's E-band filing as a push into consumer broadband is right, that would be huge for AST. x.com 

AST SpaceMobile remains unattractive on satellite handoff execution: Starlink's broadband service handles handoffs across hundreds of satellites, while ASTS is starting from zero after six years. SpaceX's proven handoff software makes Starlink's move to phone service more predictable. x.com  x.com  x.com 

SpaceX's competitive threat makes AST SpaceMobile less attractive at these levels than SpaceX and Rocket Lab. AST SpaceMobile's weekly chart shows a downtrend and strong outflows, though the stock is near marked support. x.com 

AST SpaceMobile looks set to win as European mobile operators seek an alternative to Starlink. Bloomberg reports that some of Europe's biggest operators have agreed to form a consortium to bid for satellite spectrum and offer direct-to-mobile service to counter Starlink. x.com 

AST SpaceMobile is unattractive because it is a telecom business, already a poor industry to invest in, with no regulatory protection. That is the reply to @TheLongInvest's claim that AST is a 10x to 100x stock headed for a $2 trillion market cap in five years. x.com
