Integral ILS grows AUM ~$600m in one year, to reach $3.5bn at January 2026

Integral ILS Ltd., an independent alternative investment manager focused on natural catastrophe insurance and reinsurance investments, has experienced strong growth in assets under management over the last year, starting January 2026 with $3.5 billion in committed AUM.

Integral ILS, a Bermuda headquartered investment manager specialising in insurance-linked securities, was founded in 2020 by experienced ILS industry executives Richard Lowther and Lixin Zeng.

The company has established a number of partnerships with leading players in the insurance and reinsurance sector, enhancing its access to risks and has attracted investor commitments from pension funds and other large institutional investors.

Over the now more than five years of its operations, Integral ILS has steadily increased its assets under management to increase its investment capacity for reinsurance related risks.

Looking back, Integral ILS had assets under management of around $675 million as of July 1st 2021, then increased this to over over $1.4 billion of capital committed to its ILS fund strategies by the first-quarter of 2022.

Further expansion of AUM was achieved in 2023, with Integral ILS reaching the $2 billion mark around the mid-point of that year.

The company continued to attract new inflows from investors through the following year, reaching around $2.5 billion in ILS and catastrophe reinsurance linked assets under management by the middle of 2024.

By January of 2025 the committed capital assets that Integral ILS was managing had increased to $2.9 billion.

Now, we’ve learned that the ILS manager has continued to successfully raise funds through 2025 and in preparation for the January 2026 reinsurance renewal season.

Around $600 million in additional committed AUM has been added over the last year, with Integral ILS entering January 2026 with a new high of $3.5 billion in assets under its management.

The strong and steady growth in assets managed enables Integral ILS to expand the portfolios of risk for its ILS funds and investors, while raising its stature in the reinsurance market as well.

Recall that, at this time, Integral ILS is also in the market to sponsor its first catastrophe bond, with a target to secure $200 million in US named storm retrocession from a Windrose Re Ltd. (Series 2026-1) issuance designed to hedge peak exposures in its portfolios.

Integral ILS Ltd. is just one of the insurance-linked securities (ILS) fund managers listed in our directory.
