AST SpaceMobile, Inc. (NASDAQ: ASTS) shares climbed nearly 1% overnight Sunday as retail investors linked T-Mobile’s quiet removal of Starlink branding to a newly formalized three-carrier satellite alliance.
ASTS stock had already gained 2% on Friday, closing at $58.45, though it still ended the week down 5%, extending a four-week losing streak and marking its worst weekly performance in over a month.
T-Mobile removed “with Starlink” from the T-Satellite logo and introductory statement on its main consumer website, according to a report from PCMag published Friday.
Stocktwits independently confirmed that the main T-Satellite consumer page no longer displays “With Starlink” in its branding, though T-Mobile has not publicly explained the change.
PCMag reported that Starlink references remained visible on T-Mobile’s support and business pages, and business materials still instruct customers they may see “T-Mobile SpaceX” or “T-Sat+Starlink” when connected.
The distinction is significant for AST investors: T-Mobile altered how it presents the service to consumers but has not announced any replacement of the underlying satellite network powering it.
The branding development followed last week’s announcement that AT&T (NYSE: T), T-Mobile US (NASDAQ: TMUS) and Verizon Communications (NYSE: VZ) had entered a formal joint-venture agreement, advancing a plan first outlined in May.
The venture aims to pool limited spectrum resources, improve satellite connectivity in areas without reliable cellular coverage, establish common technical specifications, and expand direct-to-device access for ordinary phones.
Wireless-industry veteran Paul Roth will serve as interim CEO of the joint venture while the three partners search for a permanent leader.
A key provision in the JV announcement directly benefits AST: the carriers confirmed that existing carrier-satellite agreements will remain in place, preserving AST’s relationships with AT&T and Verizon.
AST’s definitive Verizon agreement, announced in October last year, combines AST’s satellite network with Verizon’s 850 MHz spectrum, with commercial service targeted to begin in 2026.
AST had welcomed the original JV proposal in August, stating it expected the initiative to help enable space-based cellular broadband connectivity across the United States.
The company reported partnerships with more than 60 mobile operators covering over 3 billion subscribers, alongside $1.3 billion in contracted revenue backlog from commercial partners and U.S. government awards.
On Stocktwits, sentiment for ASTS jumped to “bullish” from “neutral” levels recorded a week earlier, accompanied by a 59% surge in 24-hour message volumes as traders debated the implications of both developments.
One Stocktwits user shared the branding report and wrote, “Buckle up on an official announcement,” also suggesting that Starlink had shifted “from Partner to competitor for T-Mobile.”
Another user called the JV announcement “big news” that “went unnoticed,” while a separate user included “T-Mobile suddenly scrubs Starlink branding” among potential AST catalysts and wrote, “Something is cooking at $ASTS.”
Despite the weekend optimism, ASTS stock remains down 20% year-to-date, leaving investors watching closely for any official carrier announcement that might confirm a shift in the competitive satellite landscape.
