Kirkland Takes Top Spot on Infrastructure Investor’s Annual Fund Formation League Table

Infrastructure Investor ranked Kirkland No. 1 on its 2026 Fund Formation League Table by both aggregate value ($57.2 billion) and number of unlisted funds formed (25), more than double the number of funds as the next leading law firm. This marks the first time in the history of Infrastructure Investor’s Fund Formation League Table that a single law firm had both the largest aggregate capital from infrastructure funds closed and the most unlisted funds launched.

Infrastructure Investor recognized Kirkland for advising on several funds, including the $2.4 billion Sustainable Asset Fund IV for Vision Ridge Partners, the $3.3 billion Ares Secondaries Infrastructure Solutions III and the $6.8 billion Macquarie Infrastructure Partners VI. Most notably, the publication recognized the Firm for advising on the €12 billion Copenhagen Infrastructure Partners V, the single largest advised fund closed around the globe.

The 2026 Fund Formation League Table covers unlisted blind pool infrastructure funds that held a final close between January 1, 2025, and December 31, 2025, with data tracked by Infrastructure Investor’s in-house researchers and verified by the law firms in question.
