FAQ
Questions people ask
What is the stablecoin market worth for investors in 2026?
Total supply was about $306 billion in October 2026 on DefiLlama's count, after a record near $321 billion in May. USDT and USDC hold about 84% of it.
Where does money get made in stablecoins?
Issuers earn interest on reserves, which makes their income sensitive to rates. Payment infrastructure such as payouts, on and off ramps, cards and B2B settlement earns per-transaction fees that hold up better when rates fall.
Are stablecoin payments real or mostly trading?
Most raw volume is trading, but McKinsey and Artemis counted about $390 billion of genuine payments in 2025, led by business-to-business flows, and identified payments grew 42% in the first eight months of 2026.
