Stablecoin Market Sheds $892M as KelpDAO Breach Triggers DeFi Unwind

Key Takeaways:

KelpDAO breach triggered $892M outflows, pushing DeFi TVL down in April 2026. Tether USDT hit $189.78B and 59.19% share, consolidating dominance after exits. Ethena USDe fell -34.39% to $3.82B, signaling ongoing DeFi risk repricing.

Stablecoin Market Holds Tight at $320.65B

In the aftermath of the KelpDAO episode, total value locked (TVL) across decentralized finance ( DeFi) contracted sharply, erasing billions within a matter of days. The disruption rippled through several DeFi protocols, including Aave, where large volumes of users unwound positions, many opting for the stablecoin exit route.

This behavior appears to align with the seven-day contraction of $892.8 million recorded in stablecoin metrics tracked by defillama.com. Tether’s USDT continues to dominate with a commanding market cap of $189.78 billion. The asset has inched higher in recent days, logging a 1.55% increase over the past week. That translates to roughly $2.89 billion in added value, extending USDT’s lead within the $320.65 billion sector total.

Behind USDT sits Circle’s USDC at $77.79 billion, which has moved in the opposite direction, posting a -1.01% weekly decline. That decline places USDC’s reduction at approximately $794 million between April 19 and April 26. The third-largest stablecoin, Sky’s USDS, representing a rebrand of the ecosystem once known as MakerDAO, now carries a market cap of $8.27 billion. USDS has trended lower, slipping -1.89% over the past week.

By simple calculation, USDS lost close to $159 million during the period between April 19 and April 26. Not far behind, Sky’s older stablecoin product, DAI, holds steady at a $4.67 billion market cap and has diverged from some peers, recording a 1.55% weekly gain.

Completing the top five is World Liberty Financial’s USD1, which stands at a $4.39 billion market cap and has posted the strongest weekly advance among leading stablecoins with a 4.34% increase.

USDe Leads With $2B in Stablecoin Outflows

While several assets, excluding USDS and USDC, registered gains, a number of other high-cap stablecoins experienced notable outflows or supply contractions. The most significant shift came from USDe, which recorded a -34.39% weekly change, bringing its market cap down to $3.82 billion.

Ethena’s USDe shed just over $2 billion during the week as the KelpDAO fallout unfolded. Paypal’s PYUSD also contracted sharply, declining -16.06% to settle at a $3.445 billion market cap.

USDG followed with a -5.71% decrease over the same period, placing its valuation at $1.114 billion. FDUSD posted a more modest -1.46% decline, bringing its market cap to $2.34 billion. Meanwhile, other stablecoin assets, such as FRAX and GUSD, likewise recorded seven-day reductions.

The week’s data essentially points to a market still processing shock rather than finding a firm footing. Capital has not exited indiscriminately; it has rotated with intent, concentrating further in dominant issuers while exposing weaker structures to sharper contractions. Whether stability returns will depend less on price movement and more on confidence rebuilding across DeFi’s core mechanisms in the weeks ahead.
