Tether disclosed a 19.7% beneficial ownership stake in Bitdeer Technologies Group, the Nasdaq-listed Bitcoin mining firm, according to a Schedule 13D filing with the SEC on June 18.
The filing, submitted by Tether's legal counsel, details the stablecoin issuer's holdings in Bitdeer following a partial share sale and an affiliate share transfer. Tether first disclosed an investment in Bitdeer in March 2025, when it participated in a private placement alongside other institutional investors.
Bitdeer, which trades under the ticker BTDR, operates Bitcoin mining facilities across North America and Asia, with a total hash rate capacity exceeding 20 exahashes per second. The company has been expanding its mining fleet and data center infrastructure as the Bitcoin network's hash rate continues to climb following the April 2024 halving.
The disclosure confirms Tether's deepening involvement in Bitcoin mining infrastructure, extending beyond its core stablecoin operations. Tether, the issuer of the $140 billion USDT token, has been diversifying its reserve holdings and investment portfolio into energy and mining assets. The 19.7% stake positions Tether as one of Bitdeer's largest shareholders, giving it significant influence over the mining firm's strategic direction as the industry consolidates following the halving's margin compression.
