DeFi TVL drops $45B in 2026 amid hacks, market downturn

DeFi TVL plunged 39% in 2026, falling from $115B to $70B, due to a market correction and record hacks. 121 attacks caused $942M in losses, with only TRON and Hyperliquid posting TVL growth.

Decentralized finance (DeFi) faced a notable downturn in 2026, with total value locked (TVL) dropping from about $115 billion in January to $70 billion by late June. This represents a 39% year-to-date decline and a $45 billion loss. The primary driver was a broad crypto market correction following the October 2025 peak, when Bitcoin surpassed $122,000 and the total crypto market cap reached $4.21 trillion before the halving event. Security issues further exacerbated the situation. In 2026, there were 121 DeFi hacks, resulting in nearly $942 million in losses. The second quarter was particularly severe, with 83–85 attacks and over $755 million lost, making it the most-hacked quarter on record. Among the top 10 blockchains, only TRON and Hyperliquid saw positive TVL growth, fueled by USDT transfers, stablecoin settlements, and on-chain perpetual futures. Major platforms like Ethereum, Solana, and Arbitrum experienced sharp declines, with Arbitrum’s TVL falling 55.3%. Despite the downturn, this DeFi cycle has been less severe than the 2021–2022 period, when TVL dropped over 70% in seven months.
