Cryptocurrency hack losses have reached $8.78 billion in 2026, according to DefiLlama data, exceeding ARK Invest's $5.6 billion estimate for on-chain revenue this year. This marks the first time since 2020 that hack losses have outpaced on-chain revenue.
A single incident drives most of this year's total. The October 29 Binance hack, valued at $6.36 billion, accounts for approximately 72% of 2026's cumulative losses. The FBI attributed the breach to North Korea's TraderTraitor hacking group. Binance reported it has covered about 98% of the stolen funds from its own reserves.
Excluding the Binance incident, 2026 hack losses fall to approximately $2.42 billion, which remains below 2025's $2.72 billion total despite a higher number of incidents—342 in 2026 compared to 148 in 2025.
DeFi Sector Faces Growing Losses
Decentralized finance protocols experienced heightened vulnerability in 2026. DeFi losses totaled $1.19 billion across 243 incidents, up from $757 million in 2025. Notable attacks included a $295 million breach of Solana-based trading platform Drift in April and a $293 million exploit of liquid restaking protocol Kelp DAO that same month. Both incidents were linked to North Korean hackers.
Revenue Decline Compounds Pressure
While hack losses surged, on-chain revenue contracted. ARK Invest's 2026 revenue estimate sits well below 2025's $8.9 billion figure. Some protocols have directed portions of revenue toward token buybacks, which helped certain tokens outperform Bitcoin this year.
Since 2017, the cryptocurrency industry has lost $26.9 billion to hacks while earning $47 billion in on-chain revenue, resulting in 57 cents stolen for every dollar earned on-chain.
The last time hack losses exceeded revenue was in 2020, when $4 billion in losses compared to $1 billion in revenue. On-chain revenue subsequently climbed to $12.5 billion in 2021 and remained ahead of hack totals through 2025.
