Guy Carpenter’s Carol Adams, Senior Vice President, Accident and Health Practice, collaborated with Oliver Wyman’s Marc Lambright, Senior Principal, on Stop Loss Market Update: Fall 2025.
Guy Carpenter and Oliver Wyman are both businesses of Marsh McLennan.
Rising healthcare costs, inflationary pressures and a surge in high-dollar claims are reshaping the medical stop loss landscape. Employers are increasingly turning to self-funding to manage costs, while insurers face mounting challenges to profitability as claims outpace premiums. At the same time, the frequency of million-dollar claims—often tied to cancer treatments, premature births and specialty therapies—continues to climb, putting pressure on traditional underwriting and portfolio strategies.
In response to these shifts, Guy Carpenter and Oliver Wyman are producing the third annual “Stop Loss Market Update.” The report explores market growth, emerging risks and how advanced analytics—including AI—are helping carriers rethink their approach to managing stop loss portfolios.
