The KelpDAO security breach on April 26, 2026 has sent shockwaves through the decentralized finance sector, triggering a massive capital exodus that saw stablecoin markets shed $892 million in just seven days. Yet the total stablecoin market capitalization remained resilient at $320.65 billion, according to data tracked by defillama.com. The incident led to a sharp contraction in DeFi total value locked (TVL), with users liquidating positions and rotating into stablecoins as a safe haven.
Funds Flow: USDT Strengthens, USDC and Others Decline
Among the upheaval, Tether's USDT proved its mettle by actually expanding its market share. Its market cap rose to $189.78 billion, now representing 59.19% of the entire stablecoin universe, a 1.55% weekly increase (approx. $2.89 billion). In contrast, Circle's USDC slid 1.01% to $77.79 billion, losing about $794 million in market cap during the same period.
Sky (formerly MakerDAO) saw its USDS stablecoin drop 1.89% to $8.27 billion (a loss of ~$159 million), while its legacy DAI stablecoin bucked the trend, rising 1.55% to $4.67 billion. World Liberty Financial's USD1 was the top performer among the top five, jumping 4.34% to $4.39 billion as capital rotated into newer, politically-backed dollar-pegged assets.
DeFi Risk Re-evaluation: USDe Crashes 34%
The biggest casualty was Ethena's USDe, which suffered a staggering 34.39% weekly collapse, dropping to $3.82 billion from roughly $5.82 billion. Over $2 billion flowed out of USDe in just seven days, as the algorithmic stablecoin's reliance on DeFi arbitrage strategies made it vulnerable to the KelpDAO fallout. PayPal's PYUSD also shrank sharply, falling 16.06% to $3.445 billion.
Other notable decliners include USDG (-5.71%, $1.114B), FDUSD (-1.46%, $2.34B), and several smaller stablecoins like FRAX and GUSD which also recorded weekly losses. The data shows the market is not indiscriminately hemorrhaging; instead, capital is being redirected toward issuers with stronger trust and simpler mechanisms.
Outlook: Recovery Depends on Restoring DeFi Confidence
The KelpDAO exploit has laid bare the fragility of complex DeFi infrastructure. While the stablecoin market managed to hold its overall size, the composition has shifted decisively toward incumbents like USDT and away from experimental models like USDe. In the coming weeks, stabilization will hinge less on price action and more on whether the broader DeFi ecosystem can rebuild confidence in its core mechanisms. For now, USDT's dominance suggests that when fear strikes, the market still prefers the oldest, simplest dollar-pegged asset.
