Tether (USDT)

Tether is the stablecoin kingpin, holding a $183.2B market cap while trading at an impeccable $0.999. Tether's zero-fluctuation peg is backed by a reserves ratio that has survived multiple crypto winters; even the average stablecoin has seen at least one depeg over the last decade, yet USDT has stayed within 0.1% of parity. In August 2026, it remains the go-to pair for roughly 70% of all BTC and ETH trades, reinforcing its role as the crypto economy's largest on-ramp. With issuance volume topping $5B weekly, Tether's dominance shows no signs of erosion.
