According to @nic__carter, USDT and USDC together account for approximately 84% of total stablecoin supply, down from a 92% peak, and this share has been declining for the last 24 months (source: @nic__carter on X, Sep 29, 2025). Based on these figures, the rest of the stablecoin market represents roughly 16% today versus about 8% at the 92% peak, a shift traders should reflect in benchmarks that assume USDT and USDC dominance when assessing pair liquidity and collateral exposure (source: calculation using @nic__carter data on X, Sep 29, 2025). For trading workflows, updating stablecoin dominance inputs to around 84% for USDT plus USDC can help align routing, slippage expectations, and risk sizing with current market composition versus prior assumptions near 90 percent concentration (source: inference from @nic__carter data on X, Sep 29, 2025).
