AST SpaceMobile, Inc. (ASTS) shares climbed nearly 1% overnight Sunday as retail investors linked a quiet T-Mobile website change to a broader satellite industry shakeup.
ASTS stock had risen 2% on Friday to close at $58.45, but 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 by PCMag published Friday.
The page no longer named SpaceX or Starlink Mobile, and T-Mobile had not publicly explained the change at the time of reporting.
Stocktwits independently confirmed that the main T-Satellite consumer page no longer displays “With Starlink” in its branding, adding weight to the speculation circulating among retail investors over the weekend.
PCMag reported that Starlink references remained visible on T-Mobile’s support and business pages, with business materials still referencing “T-Mobile SpaceX” and “T-Sat+Starlink” for connected customers.
The branding shift arrived shortly after AT&T (T), T-Mobile US (TMUS), and Verizon Communications (VZ) formalized a satellite joint-venture agreement last week, advancing a plan first outlined in May.
The venture aims to pool limited spectrum resources, improve satellite connectivity in coverage gaps, and establish common technical specifications across the three carriers.
Wireless-industry veteran Paul Roth will serve as interim CEO of the joint venture while the partners search for a permanent leader to guide the initiative.
A key provision in the joint-venture announcement directly benefits AST, stating that existing carrier-satellite agreements will remain in place and that partners can pursue connectivity efforts independently.
AST SpaceMobile already holds agreements with both AT&T and Verizon, including a definitive Verizon deal announced in October last year combining AST’s satellite network with Verizon’s 850 MHz spectrum.
AST welcomed the original joint-venture proposal in August and reported partnerships with more than 60 mobile operators covering over 3 billion subscribers worldwide.
The company also reported approximately $1.3 billion in contracted revenue backlog from commercial partners and U.S. government awards as of August.
Sentiment for ASTS on Stocktwits jumped to “bullish” from “neutral” levels seen a week ago, accompanied by a 59% surge in 24-hour message volumes on the platform.
One Stocktwits user shared the branding report and said, “Buckle up on an official announcement,” while also arguing that Starlink had shifted “from Partner to competitor for T-Mobile.”
Another user called the joint-venture announcement “big news” that “went unnoticed,” and a separate user included “T-Mobile suddenly scrubs Starlink branding” among potential AST catalysts, adding, “Something is cooking at $ASTS.”
Despite the overnight enthusiasm, ASTS stock remains down 20% year-to-date, leaving retail bulls watching closely for any official carrier announcement that could validate the weekend speculation.
