KelpDAO exploit causes $10.5B drop in DeFi TVL, AAVE suspends rsETH markets

The KelpDAO exploit has caused a $10.59 billion drop in DeFi TVL, down 10.64% in 24 hours. The Polymarket contract for Ethereum above $1,700 on April 19 sits at 100% YES, while the market for Ethereum reaching $10,000 by December 31, 2026 holds at 4% YES.

Market reaction

The hack, the largest DeFi exploit of 2026, drained approximately $293 million through a vulnerability in a cross-chain bridge. Over 20 blockchains were affected, including major Ethereum Layer-2s. Aave suspended rsETH markets, and the attacker converted roughly $250 million into ETH using Tornado Cash. Aave’s TVL fell by up to 22% amid whale withdrawals and significant bad debt.

Why it matters

The Ethereum above $1,700 on April 19 contract remains at 100% YES, meaning the market sees no risk of ETH dropping below that level in the near term. The more telling signal is the 2026 price market: the contract for Ethereum reaching $10,000 by December 31, 2026 is unchanged at 4% YES, suggesting traders view the exploit as a contained event rather than something that alters Ethereum’s multi-year outlook.

Trading volume tells a different story. USDC traded in the Ethereum 2026 market was $420 over the last 24 hours, with a face value of $12,416. It takes $1,323 to move the price by 5 points, which points to thin liquidity rather than strong conviction.

What to watch

For traders, a YES share priced at 99¢ pays $1 if Ethereum stays above $1,700 by April 19. The risk is that further vulnerabilities surface or regulators respond with freezes or enforcement actions that pressure ETH price.

Watch for announcements from the Ethereum Foundation or major exchanges about security measures or asset freezes, which could shift sentiment quickly. ETH/BTC ratio movement would also signal whether the damage is spreading beyond Ethereum-specific protocols.
