USDT closes in on ETH's market cap

Tether's USDT stablecoin is approaching Ethereum's total market capitalisation, a milestone that would mark the first time a dollar-pegged asset has overtaken the second-largest proof-of-stake network by market value.

The convergence reflects two forces running in opposite directions: USDT supply has expanded steadily as demand for on-chain dollar liquidity grows across emerging markets and DeFi, while ETH's market cap has faced pressure from a prolonged period of price consolidation. The gap between the two has narrowed to the point where a modest ETH pullback or a fresh Tether mint could close it entirely.

For crypto market structure watchers, a USDT flip would be a notable dominance signal — stablecoins absorbing a larger share of total crypto market cap typically indicates risk-off positioning or a rotation out of volatile assets into dollar equivalents, even if the underlying driver here is organic USDT growth rather than a mass ETH exit.
