Stablecoin Market Starts Swelling Again

As of this weekend, tether ( $USDT) remains the unquestioned heavyweight of the sector, holding a towering $189.63 billion market valuation; the asset posted a mild 0.05% increase over the past week. $USDT’s share of the $322.74 billion stablecoin market now stands at 58.76%, giving tether a commanding lead over the rest of the sector and further cementing its role as the dominant liquidity vehicle across the crypto economy.

Defillama.com stablecoin stats show that Circle Internet Group’s $USDC showed a bit more energy, posting a 2.08% gain over the last seven days as it comfortably held onto the No. 2 position with a $78.96 billion market capitalization. Roughly $1.61 billion in fresh inflows poured into $USDC between May 3 and May 10, 2026, giving the stablecoin one of the strongest weekly performances among the sector’s largest issuers.

Sky’s USDS claimed the bronze position with a $7.88 billion market cap, though the token clearly endured a bruising week after slipping 6.37%. Meanwhile, Sky’s DAI held steady in fourth place at $4.66 billion, managing a modest 0.63% increase over the same stretch. Rounding out the top five was World Liberty Financial’s USD1 at $4.43 billion, which appeared content to idle this week as the stablecoin drifted 2.12% lower.

After weeks of persistent outflows, the yield-bearing stablecoin USDe managed by Ethena finally reversed course with a 1.6% weekly gain, placing it sixth overall with a $3.96 billion market cap this weekend. Paypal’s PYUSD followed behind at $3.41 billion, though the stablecoin showed signs of renewed activity after climbing 1.11% over the last seven days. Meanwhile, Blackrock’s BUIDL posted a 5.81% increase this week, lifting the tokenized Treasury fund to $2.986 billion.

At the same time, Circle Internet Group’s USYC, another U.S. Treasury-backed product in the same category as BUIDL, added 2.68% during the period. Circle Internet Group’s USYC now carries a $2.981 billion valuation, further strengthening the presence of tokenized Treasury-backed products among the sector’s largest dollar-pegged assets.

Lastly, in the No. 10 position, $USDG recorded a much larger 11.89% weekly increase to reach $2.658 billion. Among the top ten stablecoins, $USDG delivered the strongest gain over the past seven days. The latest inflows since May 3 suggest capital continues to rotate back into dollar-pegged crypto assets, even as performance among the sector’s largest stablecoins remains sharply divided.
