Tether, the issuer of the world’s largest stablecoin USDT, moved 951 bitcoin (BTC) worth approximately $70.5 million from a Bitfinex hot wallet into its dedicated bitcoin reserve address on April 15, 2026. The transfer brings Tether’s total bitcoin holdings to 97,141 BTC, making it the second-largest known private corporate bitcoin holder, trailing only MicroStrategy.
Transaction Details and Accumulation Pattern
Onchain blockchain explorers flagged the transfer on Wednesday. The movement is an internal shift between Tether and Bitfinex, which share the same parent company. It likely serves security and accounting purposes, moving the coins from a hot wallet to a cold reserve address. Just five days earlier, on April 10, Tether also acquired a total of four bitcoin. The April 15 purchase is smaller than Tether’s typical quarterly buys. On Jan. 1, 2026, the company moved 8,888.8 BTC (approximately $778 million) to close the fourth quarter of 2025. A similar 961 BTC transfer occurred on Nov. 7, 2025, indicating periodic mid-quarter top-ups.
Tether has been consistently accumulating bitcoin since 2023, when it announced a policy of allocating up to 15% of quarterly net realized operating profits toward bitcoin purchases. CEO Paolo Ardoino has described bitcoin and gold as assets that will outlast fiat currencies. The BTC holdings are treated as surplus reserve — they do not back the circulating USDT supply on a 1:1 basis. The bulk of Tether’s reserves remain in cash equivalents and U.S. Treasuries, representing over $185 billion in USDT in circulation.
Scale and Market Position
At current prices near $74,000 per coin, Tether’s 97,141 BTC reserve carries a market value exceeding $7.1 billion. The company has reported unrealized gains of approximately $2.175 billion on the position and has never sold from the reserve since the program began. Tether’s reserve address now ranks as the fifth-largest single bitcoin address globally, trailing some exchange wallets and government-held addresses. As the second-largest corporate bitcoin holder, Tether’s buying rhythm is publicly verifiable through blockchain explorers.
The company’s biggest quarterly transfer occurred on Sep. 30, 2025, when it added approximately 8,888 BTC valued near $1 billion. Another large transfer took place on Dec. 30, 2024, adding 7,629 BTC worth roughly $700 million. Analysts expect Tether to continue accumulating bitcoin at a similar pace through the remainder of 2026, as long as quarterly profits persist.
Market Impact and Outlook
These regular transfers represent steady institutional buying pressure on the bitcoin market. Tether does not acquire bitcoin during speculative runs; purchases are tied to profit cycles and often occur near quarter-end dates or during price dips. The bitcoin reserve serves as a hedge against inflation and currency devaluation. With Tether recently engaging KPMG for its first full independent financial audit of USDT reserves, transparency is improving, which could further strengthen market confidence in the stability of the USDT ecosystem.
