Tether’s reach into US public markets now totals about $4.8 billion, spread across 13 listed companies, according to a review of regulatory filings. The stablecoin issuer is not just holding Treasuries or crypto. Its positions touch video streaming, Bitcoin treasuries, gold royalties, mining, payments, and even satellites.
Rumble and Twenty One Capital
The largest links include Rumble, the Nasdaq-listed video platform. Tether holds a 50.3% stake when warrants are counted, but it keeps voting control below 9.9%. Rumble streams Donald Trump Jr.’s podcast and is also a major advertising partner. Tether has committed $50 million per year in advertising over two years starting in February 2026. Rumble booked $5.54 million from that arrangement in the second quarter, about 14% of its $40.4 million in revenue, and $6.73 million in the six months ended June 30, 2026, the filing review says. Tether also backs Twenty One Capital, a Bitcoin treasury firm. Tether and Bitfinex became majority owners by supplying BTC, and Tether could nominate four of seven board members. The firm now trades at roughly 0.6 times the value of its Bitcoin.
Gold, Mining, and Payments
Tether’s gold-related holdings are broad. It owns about 27% of Elemental Royalty after dilution, down from 31%. Executive chairman Juan Sartori is also a Tether principal. Tether holds 12.6% of Gold.com, which says Tether accounted for more than 25% of its revenue in a recent quarter and generated $1.2 billion in fiscal 2026 business activity with Tether. Smaller stakes include Versamet Royalties at 12.6%, Metalla Royalty at 14.6%, Gold Royalty at 14.4%, and Aurelion at 12%. Tether also owns about 8% of Antalpha and 19.7% of Bitdeer. It controls Adecoagro, an agricultural group that has run Bitcoin mining pilots.
Space, SDEV, and Smaller Bets
Tether invested in Satellogic, the satellite firm where former Treasury Secretary Steven Mnuchin is a major holder. It has beneficial ownership of 9.9% in Stablecoin Development Corporation, a SKY treasury firm that has lost about 99% of its value since Tether got involved. Tether also became a holder in VCI Global through its stake in payments firm Oobit. Separately, Powerlaw Corp claims it acquired about $20 million of Tether equity through a fund. That claim is harder to verify from public filings.
What the $4.8B Shows
The total is dominated by Twenty One, Rumble, and Adecoagro. Still, the list shows how far Tether has moved beyond issuing a dollar-pegged token. It is using its balance sheet to take board seats, fund advertising, hold royalties, and back Bitcoin treasuries. The strategy may be opportunistic, but it makes Tether a major financial player in markets that have little to do with stablecoin reserves.
