Web3 Losses Reach $766.4 Million in September 2026, CertiK Data Shows

What happened

CertiK data showed that confirmed Web3 vulnerability attacks and phishing incidents caused about $766.4 million in total losses in September 2026, the highest monthly loss of the year and the month with the most incidents in 2026.

Confirmed

Global impact / market context

Large losses from Web3 exploits and phishing can reduce the cash available to affected platforms, which means they have less money for operations. This can force them to cut spending, raise new money, or pass costs to users.

Confirmed

Big Web3 losses can make investors more careful about holding tokens tied to affected networks. If hacks keep happening, some investors may move money to safer assets, reducing prices and trading activity in smaller crypto markets.

Analyst inference

What to watch

1. Watch whether CertiK updates its September 2026 loss total or incident count, because the article says these figures are the highest and most numerous so far this year. Confirmed
2. Watch whether Bitget and Liquid Network announce refunds, recovery plans, or new security measures after the reported losses, since those steps could affect user trust and cash available. Proposed
3. Watch whether other Web3 platforms report similar attacks, because more incidents could push investors to reduce exposure to smaller networks and tokens. Analyst inference
