In 2026, crypto hacker losses hit $8.78 billion, surpassing on-chain revenues for the first time.

According to BeInCrypto, DefiLlama data shows that crypto hacking losses in 2026 have reached $8.78 billion, exceeding ARK Invest's estimate of $5.6 billion in on-chain revenue for the year, marking the first time since 2020. In a November 12 post, ARK's Lorenzo Valente cited Token Terminal and DefiLlama data, stating that the crypto industry has lost $26.9 billion to hacking attacks since 2017, while on-chain revenue stood at $47 billion.

The October 29 Binance hack involved $6.36 billion, accounting for approximately 72% of the total 2026 losses, which the US Federal Bureau of Investigation attributed to the North Korean hacker group TraderTraitor; Binance stated it has already covered roughly 98% of the stolen funds using its own reserves. Excluding the Binance incident, 2026 losses were around $2.42 billion, down from $2.72 billion in 2025, though the number of recorded incidents rose to 342, compared to 148 in 2025.

DeFi protocols lost $1.19 billion in 2026 across 243 events, representing a 58% increase from the $757 million lost in 2025. ARK's estimate for 2026 on-chain revenue falls below the $8.9 billion recorded in 2025.
