Rumble shares surge 14.85% after-hours as Tether buys 1M shares, boosting stake to $680M.

Rumble surged 14.85% in after-hours trading following a major investment by stablecoin giant Tether, which purchased 1.06 million shares for $5.75 million, raising its stake to 104.4 million shares valued at $680 million. The move signals Tether’s continued confidence in Rumble’s cloud and crypto integration strategy, including a $150 million GPU purchase and $100 million advertising deal. The stock’s rally also aligned with broader gains in data center and high-performance computing stocks. While a legal dispute with Google over antitrust claims exists, it did not detract from the positive momentum driven by Tether’s strategic support and Rumble’s expansion into crypto infrastructure.
