Millburn Ridgefield LLC
Catalyst/Millburn Hedge Strategy Fund reported above $10B in AUM
Summary: A GlobeNewswire release from Catalyst Funds reported that the Catalyst/Millburn Hedge Strategy Fund (MBXIX) surpassed $10 billion in assets under management. The release describes MBXIX as a managed-futures fund and says the fund's approach is grounded in a systematic investment process developed by Millburn Ridgefield LLC. The figure is treated as source-reported product AUM for MBXIX, not complete Millburn firm AUM or independent 9AT validation.
Why it matters: The update may matter to due-diligence readers as a public product-scale signal tied to Millburn's systematic managed-futures process, while the press-release posture and product-vs.-firm distinction require careful attribution.
Summary
A GlobeNewswire release from Catalyst Funds reported that the Catalyst/Millburn Hedge Strategy Fund (MBXIX) surpassed $10 billion in assets under management. The release describes MBXIX as a managed-futures fund and says the fund’s approach is grounded in a systematic investment process developed by Millburn Ridgefield LLC.
The item is scoped to the source-reported MBXIX product milestone. It should not be read as complete Millburn firm AUM, product-performance evidence, suitability analysis, capacity analysis, or independent 9AT validation of the $10 billion figure.
Why it matters
For due-diligence readers, the useful signal is that a public wire release is describing substantial product scale in a managed-futures strategy connected to Millburn’s systematic process. That may prompt follow-up questions about product concentration, manager capacity, strategy implementation, investor composition, and how a mutual-fund product relates to the broader Millburn platform.
The signal is limited by source posture. This is a Catalyst Funds / GlobeNewswire press-release item, so the product-AUM claim is attributed to the release rather than treated as independently verified market evidence or as a recommendation about MBXIX, Millburn, managed futures, or any allocation decision.
Source notes
- GlobeNewswire / Catalyst Funds release: https://www.globenewswire.com/news-release/2026/06/04/3306616/0/en/the-catalyst-millburn-hedge-strategy-fund-mbxix-surpasses-10-billion-in-assets-under-management.html
- Source posture: press release. The source names Catalyst Funds, MBXIX, managed futures, Millburn Ridgefield LLC, and the reported $10 billion AUM milestone.
- Limitation: the source supports product-scale and Millburn relationship context only. It does not establish complete Millburn firm AUM, product performance, suitability, current capacity, or independent 9AT validation.
9AT filing context
Public ADV/profile context maps Millburn Ridgefield LLC to CRD 148870 / SEC file 801-60938. The analyst handoff reports about $8.7 billion in reported regulatory AUM/profile scale, 59 employees, 25 advisory employees, 6 private funds, SMA flag true, ERA flag false, public domains millburncorp.com and millburn.com, and a 2026-03-26 ADV submission.
That context helps identify the adviser and separate adviser-profile data from the MBXIX product-AUM headline. It does not validate the press-release product figure, product performance, product capacity, investor flows, or future returns. No 13F or Form 5500 context is used for this item because those filing datasets do not validate the MBXIX product-AUM milestone.
What to watch
Watch for Catalyst or Millburn follow-up disclosures that clarify product flows, investor mix, capacity management, fee/share-class context, strategy implementation, or how the MBXIX milestone relates to Millburn’s broader managed-futures platform. Also watch later public filings or primary materials for any changes in adviser-reported scale, product positioning, or manager/product relationship language.
