Allstate Corp. has reported $777 million in estimated pretax catastrophe losses for May, attributing the figure primarily to three large-scale wind and hail storm events. The insurer stated that 11 separate catastrophic events occurred in May, with approximately 70% of the month’s losses concentrated in just three of those events.
Catastrophe Losses Overview
The combined catastrophe losses for April and May totaled $1.37 billion, bringing Allstate’s year-to-date catastrophe losses to nearly $2.54 billion when combined with the $1.17 billion reported for January and February. The early-year losses were largely driven by wildfire activity in Southern California.
Industry-Wide Storm Activity
Broader industry data reflects heightened storm activity across the United States in 2025. Gallagher Re reported that through May, the US experienced at least eight separate severe convective storm events, each generating more than $1 billion in insured losses. According to data cited by Aon, at least two severe storm systems that swept through the United States in May likely resulted in insured damages amounting to several billion dollars.
Comparison to Previous Year
Allstate’s catastrophe losses in May were down compared to May 2024, when the company estimated $1.48 billion in pretax losses from 14 events. The 2024 storms largely affected Texas, Colorado, and Illinois.
