Summary
Citadel's flagship Wellington fund posted a 10.2% return for 2025, according to people familiar with the firm's performance cited by Bloomberg. The result marks a notable inflection point in the competitive landscape of elite multistrategy hedge funds, as it represents the first year Wellington has trailed Millennium Management since 2020. Millennium delivered a 10.5% gain for the same period, edging out Citadel's marquee offering by 30 basis points.
The performance differential carries strategic weight given the historical record between these two powerhouses. Since 1990, Millennium has outperformed Citadel on nine occasions, according to Bloomberg documents reviewed in connection with this report. Wellington's solid but second-place finish in 2025 illustrates the intensifying competitive environment within the multistrategy hedge fund sector, where performance variance among top-tier managers has narrowed in recent years.
Both funds navigated a volatile 2025 marked by sharp market swings and macroeconomic uncertainty. Citadel's double-digit return demonstrates resilience across its portfolio construction and risk management framework, though the margin of underperformance relative to Millennium suggests nuanced differences in strategic positioning or tactical execution during the period.
The Wellington result underscores ongoing investor focus on relative performance among the largest alternative asset managers. With $68 billion in assets under management as of mid-2025, Citadel remains among the industry's most substantial players, and returns of this magnitude continue to justify institutional allocations to the firm's multistrategy platforms, despite the competitive narrowing evidenced by Millennium's year-over-year outperformance.
