Tether has capped off 2025 with another sizable Bitcoin purchase, adding 8,888 BTC to its balance sheet and pushing its disclosed holdings beyond 96,000 Bitcoin. The acquisition, confirmed by CEO Paolo Ardoino, was completed on New Year’s Eve and underscores the stablecoin issuer’s steady commitment to building a large Bitcoin reserve.

At current prices at the time of purchase, the latest batch was valued at roughly $780 million. With this move, Tether’s primary Bitcoin address now ranks as the fifth-largest known Bitcoin wallet globally, trailing only major custodial platforms such as Binance, Robinhood, and Bitfinex. Among privately held companies, Tether sits near the top, second only to a handful of firms with long-standing Bitcoin treasury strategies.
A consistent accumulation strategy
The New Year’s Eve purchase was not a one-off. It followed a clear pattern Tether has maintained throughout the year. The company has been allocating up to 15% of its quarterly earnings into Bitcoin, gradually building one of the most significant corporate crypto holdings in the market.
Earlier in 2025, Tether’s Bitcoin balance briefly exceeded 100,000 BTC. Subsequent declines in reported holdings sparked speculation that the company was quietly selling Bitcoin. Ardoino pushed back on those claims, explaining that some of the Bitcoin had been contributed to Twenty One Capital, a Tether-backed entity.
As of New Year’s Day, Twenty One Capital held 43,514 BTC, making it the third-largest public company Bitcoin holder, behind Mara Holdings and Strategy. Taken together, the figures suggest that while Tether’s direct holdings fluctuate, its broader Bitcoin exposure remains substantial.
Beyond Bitcoin: gold and traditional reserves
Bitcoin is only one part of Tether’s evolving reserve strategy. In the third quarter of 2025, the company purchased 26 tons of gold, marking a larger quarterly acquisition than any reporting central bank during the same period. That buy lifted Tether’s total gold holdings to 116 tons, placing it among the world’s top 30 gold holders.
Today, Tether’s reserves are a mix of US Treasurys, Bitcoin, and gold. The diversification reflects an effort to balance liquidity, yield, and long-term value, but it has also drawn increased scrutiny.
Ratings agency S&P recently downgraded USDT’s score from “constrained” to “weak,” citing concerns around transparency and concentration risk. Some industry figures have echoed those worries. Former BitMEX CEO Arthur Hayes has publicly questioned the growing share of Bitcoin and gold within Tether’s reserves, arguing that it could introduce additional volatility during stressed market conditions.
Corporate interest in Bitcoin continues to grow
Tether’s latest purchase comes amid a wider surge in corporate Bitcoin accumulation. Japan-listed Metaplanet announced this week that it added 4,279 BTC to its treasury, bringing its total holdings to 35,102 Bitcoin. The company has been steadily increasing its exposure as part of a long-term balance sheet strategy.
Meanwhile, Strategy, already the largest corporate Bitcoin holder, continued to raise capital through equity and debt offerings in 2025. Its Bitcoin stash has now climbed above 670,000 BTC, further widening the gap between Strategy and other corporate holders.
This wave of accumulation highlights a broader trend: more companies are treating Bitcoin as a strategic reserve asset rather than a short-term trade. While approaches differ, the underlying belief in Bitcoin’s long-term role appears to be gaining traction.
Looking ahead
Tether’s New Year’s Eve purchase reinforces its position as one of the most influential players in the Bitcoin market. The company’s growing exposure to both Bitcoin and gold signals confidence in hard assets, even as questions around transparency and risk management persist.
As 2026 begins, investors and analysts alike will be watching closely to see whether Tether maintains its aggressive accumulation pace, adjusts its reserve mix, or offers greater clarity into how those assets are managed. For now, the message is clear: Tether intends to remain a major force in the evolving landscape of corporate Bitcoin ownership.
