SEC Filing Shows Tether Expanding Bitdeer Stake to 21%

Tether Increases Stake in Bitcoin Miner Bitdeer

On March 18, 2025, Tether, the issuer behind the USDT stablecoin, has raised its stake in Bitcoin mining company Bitdeer (BTDR), continuing its investment strategy that began nearly a year ago.

According to a filing with the U.S. Securities and Exchange Commission, Tether now holds a 21% ownership in the Singapore-based mining firm. The increased investment was funded with the company’s working capital.

Tether’s first move into Bitdeer came in May 2024, when it invested $100 million in exchange for 18.59 million Class A shares, with an additional option to purchase 5 million more shares at $10 each.

As Tether continues to capitalize on its record profits of $13 billion in 2024, the company is diversifying its portfolio. In addition to Bitdeer, Tether has also acquired a stake in Italy’s Juventus FC and is reportedly bidding for a majority share in the Latin American agricultural commodities firm Adecoagro.

Bitdeer’s stock price has remained steady in pre-market Nasdaq trading, holding at $10.56 per share.
