Tether disclosed a 19.7% beneficial ownership stake in Bitdeer Technologies Group this week, according to a Schedule 13D/A filing with the SEC. The stablecoin issuer, through its Tether Global Investments Fund, now holds 37.7 million Bitdeer Class A ordinary shares. The filing also revealed a partial sale of 627,021 shares by Tether affiliates, though the company retains a major position.
What the SEC filing shows
The Schedule 13D/A, originally published on SEC EDGAR, lists Tether Global Investments Fund as the reporting entity. Tether’s stake makes it one of Bitdeer’s largest shareholders. The partial sale and internal transfer among affiliates appear to be portfolio management, not an exit strategy. Tether still holds tens of millions of shares.
Why mining stocks like Bitdeer matter
Bitdeer is one of several Bitcoin miners angling for a pivot into AI and high-performance computing infrastructure. That dual narrative — mining plus compute — has drawn interest from investors looking beyond pure crypto economics. But mining stocks remain tied to Bitcoin price, hashprice, energy costs, debt levels, hardware efficiency, and capital-market appetite. Tether’s investment signals confidence in Bitdeer’s long-term positioning, even as it trims a small slice of shares.
Tether’s broader infrastructure play
The disclosure fits a pattern. Tether has been deploying profits from its stablecoin operations into Bitcoin, mining, energy, and adjacent infrastructure. The Bitdeer stake is one piece of that push. By holding a material stake rather than just buying hash contracts, Tether gets direct exposure to the miner’s operational upside — and risk.
The timing isn’t trivial. Mining margins have tightened in 2026 as hashprice struggles and energy costs remain elevated. A large cash-rich backer like Tether can help Bitdeer weather leaner quarters or fund new buildouts.
What’s next
Bitdeer hasn’t commented on the filing publicly. Tether’s next quarterly attestation, due in July, may shed more light on how much of its balance sheet is tied up in listed mining equities. For now, the market knows exactly where Tether stands: a 19.7% owner that recently lightened its position by a sliver, but isn’t walking away.
