Tether ended 2025 with another decisive move into Bitcoin, adding 8,888 BTC on New Year’s Eve and lifting its disclosed holdings above 96,000 Bitcoin.
The purchase, confirmed by CEO Paolo Ardoino, reinforces the stablecoin issuer’s position as one of the largest active accumulators in the market.
Key takeaways:
Tether added 8,888 BTC at year-end, pushing its disclosed Bitcoin holdings above 96,000.
The company now controls the fifth-largest known Bitcoin address globally and ranks second among privately held corporate BTC treasuries.
The purchase continues Tether’s policy of allocating a portion of quarterly earnings into Bitcoin as a long-term reserve asset.
With that addition, Tether now controls the fifth-largest known Bitcoin address globally, trailing only major platforms such as Binance, Robinhood, and Bitfinex. Among privately held companies, Tether ranks second by Bitcoin holdings.
A Systematic Bitcoin Accumulation Strategy
The year-end buy is not an isolated event. Tether has been consistently allocating up to 15% of its quarterly earnings into Bitcoin, effectively turning BTC into a long-term reserve asset rather than a tactical trade. The most recent purchase was valued at roughly $780 million at the time of execution.
While the company’s Bitcoin balance has fluctuated during the year — at one point exceeding 100,000 BTC — Ardoino has pushed back against speculation that Tether was selling into the market. He clarified that some transfers were tied to contributions to Twenty One Capital, a Tether-backed entity.
Gold Joins Bitcoin in Tether’s Reserve Playbook
Bitcoin is only part of Tether’s growing exposure to hard assets. In the third quarter of 2025, the company acquired 26 metric tons of gold, a larger quarterly purchase than any reporting central bank. That brought Tether’s total gold holdings to 116 tons, placing it among the world’s top 30 gold holders.
This evolving reserve mix — spanning U.S. Treasurys, Bitcoin, and gold — has attracted scrutiny. S&P Global Ratings recently downgraded USDT’s assessment from “constrained” to “weak,” citing transparency concerns and asset concentration risks. Industry figures such as former BitMEX CEO Arthur Hayes have also raised questions about the growing share of volatile assets within Tether’s reserves.
Tether’s Expanding Bitcoin Orbit
The Bitcoin exposure extends beyond Tether’s own balance sheet. Twenty One Capital, the firm referenced by Ardoino, held 43,514 BTC as of New Year’s Day, making it the third-largest public-company Bitcoin holder behind Mara Holdings and Strategy.
This positioning places Tether at the center of a wider network of Bitcoin-heavy entities, amplifying its influence over corporate BTC flows even beyond its direct holdings.
Corporate Bitcoin Accumulation Accelerates
Tether’s year-end allocation comes amid an intensifying corporate race to build Bitcoin treasuries. Japan-listed Metaplanet added another 4,279 BTC in late December, bringing its holdings to 35,102 BTC. Meanwhile, Strategy continued raising capital through equity and debt issuance, pushing its already dominant Bitcoin stack beyond 670,000 BTC.
Together, these moves underscore a broader shift: Bitcoin is increasingly being treated not just as a speculative asset, but as a long-term reserve instrument for corporations willing to absorb volatility in exchange for monetary exposure outside traditional systems.
As 2025 closed, Tether’s latest purchase sent a clear signal. The world’s largest stablecoin issuer is not trimming risk — it is steadily entrenching itself as one of Bitcoin’s most committed corporate holders.
