The stablecoin sector’s total market capitalization increased by over $2 billion in the seven days leading up to May 10, pushing its total value to $322.74 billion, according to data from Defillama.
The growth highlights the critical role of stablecoins as a core pillar of crypto market liquidity, a point reinforced by Coinbase’s recent earnings. The exchange reported $305 million in stablecoin revenue for Q1 2026, supported by record average USDC balances of $19 billion on its platform, according to its latest earnings call. Coinbase now holds over a quarter of the entire USDC supply and captures roughly half of its underlying economics.
The influx of more than $2 billion into stablecoins over the past week suggests a buildup of dry powder on the sidelines of the crypto economy. While the overall crypto market has faced headwinds, with Coinbase reporting a 21 percent sequential revenue decline, the growth in stablecoins provides a counter-signal. Tether’s USDT, the largest stablecoin, holds a market capitalization near $190 billion, anchoring the sector.
This growing pool of stable capital is widely interpreted as potential buying power that could fuel price appreciation in major assets like Bitcoin and Ethereum. However, the ecosystem is also witnessing rising internal competition. Ripple, following its 2025 settlement with the SEC, is promoting its own RLUSD stablecoin, which presents a competitive alternative to XRP for value capture within its payment network. This dynamic, coupled with Coinbase’s strategic focus on its Base network for stablecoin transactions, shows that even as capital flows into the system, the battle for where it is deployed is intensifying.
