AM Best Reports Commercial Auto Insurance Improvement
The U.S. commercial auto insurance market, a sector that has struggled with consistent underwriting losses since 2015, is showing signs of stabilization. A recent report from AM Best highlights that while insurers still faced a $2.2 billion underwriting loss in 2025, this figure represents a 55% improvement over the previous year. This shift is notable for a business line that has historically underperformed compared to other commercial insurance sectors.
Several metrics support this trend. Net premiums written grew by 6% year-over-year, while incurred losses remained relatively flat. The sector's combined ratio improved to 96.6 in 2025, down from 101.4 in 2024. Furthermore, adverse reserve development hit a 10-year low, and early data from the first half of 2026 shows a direct loss ratio of 66.1. Notably, the physical damage segment achieved a $2.4 billion gain, which David Blades of AM Best attributes to proactive fleet monitoring and maintenance technologies that reduce preventable accidents.
Context/Opinion: For software developers and LIMS providers, this data underscores the tangible ROI of telematics and predictive maintenance platforms. As insurers reward clients who utilize data-driven fleet management, demand for sophisticated monitoring software is likely to grow. However, the liability segment remains a significant hurdle, with over $4.6 billion in losses for 2025. While this is an improvement from 2024, liability claims—driven by social and economic inflation—continue to dominate the sector. Buyers may see some pricing relief, as rate increases in Q2 2026 were the lowest in a decade, but long-term profitability will depend on managing these complex liability costs.
Why it matters
The insurance sector's reliance on fleet monitoring technology to reduce losses highlights a growing market for data-driven risk management software.
