The circulating supply of Tether has reached a new all-time high of $188 billion, according to CEO Paolo Ardoino, marking continued expansion of the world’s largest stablecoin amid sustained global demand. Data from Tether’s transparency page and market trackers shows supply at approximately $187.8 billion to $187.9 billion as of April 20–21, 2026, with total market capitalization approaching $188 billion. Over the same period, 24-hour trading volume exceeded $118 billion, underscoring USDT’s central role in crypto market liquidity.

The milestone caps a steady growth trend over the past year. Circulating supply stood at around $160 billion in July 2025, rising to roughly $182 billion by October and crossing $184 billion in early April 2026 before reaching the latest peak. Tether’s reserves remain a key point of scrutiny. Its latest attestation, dated December 31, 2025, reported total assets of $192.88 billion against liabilities of $186.54 billion, leaving excess reserves of about $6.34 billion. The company said reserves are primarily allocated to high-quality U.S. Treasuries and confirmed it is undergoing its first full independent audit with KPMG, with support from PwC.

On-chain distribution data shows USDT remains concentrated across two major networks. Ethereum accounts for roughly 51.5% of supply, or about $96.7 billion, while Tron holds approximately 45.5%, or $85.4 billion. Together, the two chains represent nearly all circulating USDT.

The supply expansion comes alongside product and ecosystem growth. On April 14, Tether launched tether.wallet, a self-custodial mobile wallet aimed at expanding access to digital dollar infrastructure. The company has also reported a user base exceeding 500 million globally as of late 2025, with strongest adoption in emerging markets where stablecoins are used for remittances, savings, and day-to-day transactions. Analysts often interpret rising stablecoin supply as an increase in deployable capital within the crypto ecosystem.

Additional USDT liquidity can act as “dry powder” for trading and decentralized finance activity, particularly during periods of improving market sentiment. Tether has also maintained strong profitability, with estimates placing its 2025 earnings in the $10–15 billion range, further reinforcing its ability to expand reserves and support growing issuance. The new supply high reinforces USDT’s position as the dominant stablecoin globally, both as a trading pair and as a dollar proxy in regions with limited access to traditional banking infrastructure.
