The complete guide to dedicated insurance-linked securities fund managers
Published by GP Stakes, the private markets intelligence platform
The insurance-linked securities market is managed by a relatively small group of specialized investment firms. Unlike most alternative asset classes where hundreds of managers compete for capital, the ILS space is dominated by roughly a dozen dedicated platforms that have built deep expertise in catastrophe risk modeling, reinsurance relationships, and portfolio construction.
This directory profiles each of the 13 dedicated ILS managers in our database, including their assets under management, strategy focus, corporate affiliations, and market positioning. Combined, these managers oversee approximately $74.5B in ILS-dedicated capital, making them significant counterparties in the global reinsurance market.
Several of these managers are subsidiaries of larger alternative asset management platforms, making them relevant to GP stakes analysis. The ILS business model generates stable management fees on sticky capital, with performance fees during benign catastrophe years. This fee structure is attractive to GP stakes buyers evaluating diversified alternative managers with ILS capabilities.
The barriers to entry in ILS management are substantial. New entrants require sophisticated catastrophe modeling capabilities, established relationships with cedents and brokers, and a track record of managing through loss events. This structural moat supports the long-term value of existing ILS platforms and makes them compelling targets for strategic investment.
