Crypto lost approximately $972 million across 207 hack incidents in the first half of 2026, the highest incident count ever recorded, according to Immunefi. The dollar figure marks a continued retreat from peak-era losses, with DeFi exploit losses down 74% from their 2022 high of $2.62 billion to $680.3 million for the period.
Why it matters
The split between frequency and severity is the story. Attackers are firing more shots than ever, yet the median damage per incident is shrinking as protocols harden, audits become standard, and live-monitoring infrastructure shortens the window between exploit and response. Immunefi's data frames this as a maturation signal: more attempts absorbed by better defenses rather than fewer attempts against soft targets.
Market impact
The trend underwrites the thesis that on-chain security spending is now a cost of doing business rather than a discretionary line. For institutional allocators weighing DeFi exposure, a multi-year decline in dollar losses alongside rising incident counts is the precise pattern that argues for continued protocol-level investment, not retreat from the sector.
Frequently asked questions
-
How much did crypto lose to hacks in H1 2026?
Approximately $972 million across 207 incidents, according to Immunefi. That makes H1 2026 the highest incident count on record, even as total dollar losses stayed below $1 billion.
-
How do H1 2026 losses compare to the 2022 peak?
DeFi exploit losses fell 74% from the 2022 peak of $2.62 billion to $680.3 million in H1 2026, Immunefi reported. Attack frequency kept climbing over the same window, making the dollar decline a severity story rather than a volume story.
-
Why are crypto hack losses falling while incidents rise?
Protocol audits, standardized code reviews, and live on-chain monitoring have shortened the window between exploit and response. Immunefi frames the pattern as maturation: more attempts absorbed by better defenses, not fewer attempts against soft targets.
-
Does this make DeFi safer for institutional capital?
The multi-year decline in dollar losses alongside rising incident counts is the pattern institutional allocators look for when weighing DeFi exposure. It argues for continued protocol-level security investment rather than retreat from the sector.
-
Who reported these crypto hack figures for H1 2026?
Immunefi, a major bug bounty and security platform for crypto, published the H1 2026 figures. The data covers both CeFi and DeFi incidents across the first six months of the year.
