About 380 Stablecoins Tracked in 2026; Two Hold 83%

About 380 distinct stablecoins were tracked in mid-2026, while two tokens-Tether’s USDT and Circle’s USDC-together comprised roughly 83% of total circulating supply. The combined market size across all stablecoins was about $315 billion.

One on-chain tracker listed about 382 stablecoins in mid-2026; counts vary slightly by tracker because each includes a different set of tokens. Counting token types does not reflect how capital is distributed: USDT accounted for about $187 billion, or roughly 59% of supply, and USDC held about $75 billion, or 24%. The top five issuers together controlled nearly 89% of the market.

Most smaller tokens held only trace amounts of supply. Many were created for narrow purposes such as protocol-native liquidity, regional payment rails, experimental designs or synthetic yield products. Approximately 99% of total stablecoin supply was pegged to the U.S. dollar in mid-2026; euro- and yen-pegged projects represented only a small fraction of overall supply.

Stablecoins in active circulation fell into four main backing models. Fiat-backed coins maintain reserves of cash and short-term government debt and generally offer one-to-one redemption; USDT and USDC use this model and together made up the bulk of supply. Crypto-backed tokens are overcollateralized with other cryptocurrencies and operate through smart contracts; DAI is a long-standing example. Algorithmic designs attempt to maintain a peg through code-driven supply adjustments; the largest example, TerraUSD, collapsed in 2022 and eliminated about $18 billion in market value. A newer category of yield-bearing or hybrid stablecoins routes reserve income to holders or mixes collateral types; Sky Dollar (USDS) was an example of a sizable hybrid token, holding about $8 billion in mid-2026.

Total stablecoin supply rose from about $27 billion at the end of 2020 to roughly $315 billion by mid-2026. Growth accelerated after mid-2024, with around $75 billion added in 2024 and about $102 billion in 2025, a period that overlapped with the passage of U.S. stablecoin legislation and increased institutional use. The sector also experienced contractions: the TerraUSD collapse in 2022 and outflows in 2023 reduced supply, and a roughly $10 billion decline occurred from May 2026 to mid-2026.

Forecasts for future supply vary. Citi’s base case projects about $1.9 trillion by 2030 and up to $4 trillion in a bull case. Standard Chartered projects roughly $2 trillion by late 2028. JPMorgan’s projection ranges from $500 billion to $750 billion. Those forecasts rest on assumptions about tokenized cash flows, stablecoins replacing short-term liquidity instruments, and further integration with payments and financial services.

Market participants and observers track reserves, redemption mechanics and issuer disclosures to assess risk. Token counts changed frequently as new stablecoins launched and older projects faded; the number of tracked tokens at any moment depended on the tracker and its inclusion criteria.

The facts: about 380 stablecoins were recorded in mid-2026, total supply was about $315 billion, USDT and USDC together held about 83% of that supply, and fiat-backed models held most of the market value.
