Walleye Capital’s Chief Strategy Officer Jonathan Brenner is leaving the firm, the latest in a string of senior exits at the $9.4 billion hedge fund.

Brenner, who joined in 2018 in a marketing and investor relations role and was promoted to partner in 2022, will exit the firm after a transition that will last through the first quarter of 2026, according to a quarterly investor update sent last month. A copy of the letter was seen by Business Insider.

The departure follows Brenner’s move to Texas earlier this year. The New York-based fund, which for years was based in Minnesota and has nine global offices listed on its website, does not have a presence in Texas. Brenner’s executive bio was recently removed from the Walleye website.

“Earlier this year, we supported Jon’s relocation with his family back to Austin, TX and, following that move, have agreed on a thoughtful transition plan under which he remains an employee for several more months and a Partner of the Firm. The Capital Development and Investor Relations team will continue to be led by Erin Whitelaw and Anil Jethanandani,” the letter reads in part.

A Walleye representative declined to comment. Brenner also declined to comment.

Walleye has undergone an overhaul since Will England took over as CEO in 2023, including the shift to New York, investment strategy pivots and accompanying cuts, and a revamp of the firm’s management team. In 2024, Andrew Carney, a long-time exec who held the CEO title before England, and Mark Zeldis, chief technology officer, left the firm. Other senior departures include volatility execs Geoff Tennican and Markus Rauser, who left earlier this year.

Assets have swelled, even as the firm soft-closed its flagship Walleye Opportunities Fund, limiting new investors but allowing existing investors to add capital. The fund managed $9 billion at the end of September, according to the investor letter sent in mid-October. This figure grew to $9.4 billion as of the start of November, according to a monthly update seen by Business Insider.

Walleye is up 11.5% in 2025 and gained 0.8% in October, Business Insider previously reported.

“While the Fund will remain soft-closed, we plan to further limit additional capacity and manage subscriptions more selectively at this threshold — consistent with the guidance we have provided over the years regarding our approach at the $10 billion AUM level,” the quarterly update reads.

Including assets in Dockside Platforms, a separate business partnership between Walleye and institutional allocators that connects investors to smaller money managers through separately managed accounts, the firm’s assets exceed $13 billion.
