Summary in 3 Points • Securities class action filings rose to 121 in the first half of 2026 • AI-related filings accounted for 73% of market capitalization losses in H1 2026 • Technology sector filings reached 24, driven by AI-related cases, in H1 2026 --- Securities class action filings saw a notable increase in the first half of 2026, reaching 121 cases, up from 93 in the previous half-year. This rise was significantly influenced by filings related to artificial intelligence, which accounted for 15 cases. These AI-related filings were responsible for a substantial portion of market capitalization losses, comprising 73% of both the Disclosure Dollar Loss (DDL) and Maximum Dollar Loss (MDL) indices. The technology sector experienced a surge in filings, with 24 cases in the first half, largely driven by AI-related issues. Other litigation trends, such as cryptocurrency-related filings, showed a decline, with numbers on track to be the lowest since 2019.
The increase in AI-related securities class action filings could lead to heightened scrutiny and potential adjustments in underwriting practices for technology and AI sectors within the London Market. Insurers may need to reassess their exposure to AI-driven companies, considering the significant market capitalization losses associated with these filings. Policy wording and coverage terms might require updates to address emerging risks tied to AI developments and infrastructure. Additionally, the decline in cryptocurrency-related filings suggests a shift in focus, which could influence risk assessment and pricing strategies in the financial sector.
