Walleye Capital’s Chief Strategy Officer, Jonathan Brenner, is preparing to leave the firm, representing the most recent in a noticeable sequence of senior-level departures at the hedge fund that currently manages $9.4 billion in assets. Brenner, who originally joined Walleye in 2018 to focus on marketing and investor relations, gradually rose through the organization’s upper ranks, earning a promotion to partner in 2022. According to a quarterly investor update distributed last month—copies of which were reviewed by Business Insider—his formal departure will take place after a lengthy and carefully structured transition period extending through the first quarter of 2026. This planned handover reflects a deliberate approach to leadership changes within the firm.
The separation process coincides with Brenner’s personal move to Texas earlier in the year. Walleye, which maintains its current headquarters in New York after years of operating out of Minnesota, does not have any official office or staff presence in Texas, despite boasting nine global locations listed publicly on its website. Notably, Brenner’s executive biography has recently been removed from the company’s online leadership page, symbolizing the approaching conclusion of his tenure. Within the internal correspondence circulated to investors, management explained that the firm had supported Brenner’s relocation to Austin, Texas, along with his family. Following that relocation, Walleye and Brenner reached an agreement outlining a considered transition plan under which he would continue as both an employee and partner for several additional months. During this period, operational continuity in capital development and investor relations will remain under the supervision of senior leaders Erin Whitelaw and Anil Jethanandani, ensuring ongoing engagement with investors and the stability of client communications.
When approached for comment, representatives from Walleye declined to provide public statements, and Brenner also chose not to offer additional remarks regarding the exit or transition process. Their restraint underscores the confidentiality that often accompanies internal leadership adjustments at large financial institutions.
Brenner’s impending departure occurs amid widespread transformation within Walleye following Will England’s appointment as Chief Executive Officer in 2023. Under his leadership, the firm has undergone a sweeping organizational overhaul that has encompassed relocating its headquarters to New York, implementing shifts in investment strategy consistent with changing market conditions, executing related personnel adjustments, and significantly redesigning the leadership framework to enhance efficiency and long-term competitiveness. In the past year alone, several senior figures have left the firm, including Andrew Carney—who previously served as Walleye’s CEO prior to England—and Chief Technology Officer Mark Zeldis. Additional high-level departures have included volatility specialists Geoff Tennican and Markus Rauser, both of whom exited earlier this year. Collectively, these changes reflect a period of ongoing recalibration and strategic refinement.
Despite this considerable turnover among executives, Walleye Capital’s financial growth trajectory has remained notably strong. Firm assets have continued to expand, even as Walleye implemented a soft-close on its flagship vehicle, the Walleye Opportunities Fund. This decision limits the participation of new investors while still permitting existing stakeholders to augment their capital allocations. In mid-October, the firm’s investor update reported that assets under management had reached $9 billion as of the end of September. By the beginning of November, that figure had increased further to $9.4 billion, according to subsequent monthly updates also reviewed by Business Insider.
Performance data included in the firm’s communications indicates that Walleye posted an 11.5% gain in 2025 year-to-date, with an additional 0.8% increase recorded in October alone. These results underscore the firm’s ability to maintain competitive returns despite structural adjustments. The quarterly letter also elaborated on Walleye’s philosophy regarding capacity management, affirming that while the flagship fund will continue to remain soft-closed, leadership intends to impose stricter limitations on incremental inflows. The update emphasized that the firm will manage new subscriptions more selectively as its assets approach the $10 billion level—a position consistent with guidance Walleye has reiterated through multiple investor communication cycles in past years, highlighting its disciplined approach to maintaining fund performance and operational integrity.
In addition to the assets overseen directly within its flagship and related strategies, Walleye also manages capital through Dockside Platforms, an affiliated initiative developed through collaboration with institutional allocators. This separate venture facilitates relationships between large investors and smaller, specialized money managers by using a structure of separately managed accounts, providing access to niche expertise without direct fund participation. When these assets are aggregated with Walleye’s primary holdings, the firm’s total managed capital surpasses $13 billion in combined assets.
Taken together, Brenner’s forthcoming exit, the evolving corporate structure, and Walleye’s disciplined asset management approach illustrate a period of significant institutional transition. While the hedge fund continues to navigate executive realignment and geographic restructuring, its financial scale, investor discipline, and continued positive performance demonstrate that Walleye remains an influential force in the global alternative investment landscape.
