Tether, the world's largest stablecoin issuer, posted a staggering $15 billion net profit in 2025, with total assets surpassing $187 billion. CEO Paolo Ardoino confirmed the numbers, underscoring the growing influence of stablecoins in global finance.
Profit doubled, exceeding $10B in H1
According to Fortune magazine, Tether's total assets reached about $187 billion by end of 2025, closely matching USDT's circulating market cap. Profit had already exceeded $10 billion in the first half, eventually hitting $15 billion for the full year. This makes Tether one of the most profitable crypto firms.
Business model: stablecoin issuance + low-cost investing
Tether's earnings engine is often described as a "modern money printer." When users exchange dollars or other assets for USDT, Tether invests the funds into low-risk, high-liquidity instruments, mainly short-term US Treasuries. The high interest rate environment in 2025 generated steady interest income, the primary profit driver.
Unlike traditional banks, Tether operates with about 150 employees and no branch network. Its profit margin approaches 99%, far exceeding conventional financial institutions.
US Treasury holdings hit $135B, ranking 17th globally
Data shows Tether held roughly $135 billion in US Treasuries (direct and indirect) in Q3 2025, surpassing sovereign nations like South Korea to become the 17th largest holder worldwide.
Beyond Treasuries, Tether allocated portions of its reserves to bitcoin and gold. Gold reserves were valued at about $12.9 billion, and bitcoin holdings delivered substantial realized and unrealized gains during the bull market, further boosting overall returns.
Regulatory and transparency scrutiny persists
USDT's circulating market cap now approaches $187 billion, with daily trading volumes dwarfing all rival stablecoins combined. However, Tether's rapid growth and huge profits continue to draw questions about reserve transparency, compliance, and potential systemic risks. Despite these concerns, its market position appears secure amid expanding crypto adoption and rising demand for digital dollars.
