The total stablecoin market cap fell to $311.311 billion as of July 5, 2026, declining 0.61% over the past seven days, a drop of $1.911 billion, according to Defillama data. Tether's USDT maintained a $184.112 billion market cap and 59.14% dominance share despite a 0.43% weekly decline, while Paypal's PYUSD posted the top gain among the top 15 stablecoins, rising 4.25% to $2.836 billion. Sky Dollar's USDS fell 2.36% to $8.02 billion, marking the steepest weekly drop in the group. The movement reflects stablecoin minting and redemption activity, which traders monitor as a gauge of capital flows into and out of the crypto system.
USDT and USDC Hold Combined 82% Market Share
Tether's USDT dropped 0.43% over the week but remains the third largest crypto asset by market cap, trailing only bitcoin and ethereum. Circle's USDC sits in second place among stablecoins with a $73.098 billion market cap as of July 5, falling 1.05% over seven days. Together, USDT and USDC account for more than 82% of the entire top 15 stablecoin market cap. USDT now accounts for 59.14% of the total stablecoin market.
Stablecoin Supply Reflects Capital Flow Mechanism
Stablecoin market cap moves through a minting and redemption mechanism. Issuers mint new tokens when users deposit dollars or equivalent reserves, and they burn or redeem tokens when users withdraw. A rising total supply means more dollars are entering the crypto system through that channel, while a falling total market cap means dollars are leaving the system, assuming no depeg event occurs. Traders and analysts treat stablecoin supply as a measure of capital available to buy bitcoin and other digital assets. This week's 0.61% dip represents a small move, with the market holding near $300 billion to $310 billion for months.
PYUSD Gains 4.25% to Lead Weekly Performance
Paypal's PYUSD posted the strongest weekly performance among the top 15 stablecoins, climbing 4.25% to reach a $2.836 billion market cap. Ripple's RLUSD followed with a 0.96% gain, pushing its market cap to $1.585 billion. USDD added 1.55%, reaching $1.396 billion. No other stablecoin in the top 15 matched PYUSD's pace. Sky's original stablecoin DAI gained 0.09% to reach $4.851 billion, standing out as one of the few tokens in the top ten to post a positive week.
Sky Dollar Posts 2.36% Decline Among Top Stablecoins
Sky dollar (USDS) fell 2.36% over seven days, the sharpest decline among the group, with its market cap standing at $8.02 billion as of July 5. World Liberty Financial's USD1 dropped 1.77% to a $4.61 billion market cap. Global dollar (USDG) fell 1.19% to $2.871 billion. Ethena's USDe slipped 0.49% to $4.439 billion. Circle's USYC and Blackrock's BUIDL both held close to flat, losing 0.06% and 0.21% respectively. Among the bottom five in the top 15, Ondo's USDY stayed nearly flat at $2.157 billion, Falcon's USDf rose 0.24% to $1.258 billion, and United stables (U) gained 0.81% to $1.023 billion.
Yield-Bearing Tokens Compete for Treasury-Linked Capital
Several tokens in the bottom half of the top 15 represent tokenized money market products rather than pure trading dollars. BlackRock USD, Circle USYC, and Ondo US Dollar Yield offer exposure to short-term government debt, passing along yield from underlying Treasury holdings. These yield-bearing tokens compete for capital that might otherwise sit in traditional bank accounts or money market funds, adding a second layer to the stablecoin market beyond the trading-dollar function that USDT and USDC serve.
