US money market fund assets hit record $8.28 trillion after $66 billion weekly inflow

A $41 billion one-day move ahead of month-end rebalancing helped lift year-to-date inflows to $172 billion in the week ending May 28.

Fact Check
Multiple independent sources corroborate the $8.28 trillion record figure for the week ending May 28, 2026. The Kobeissi Letter X post matches the article headline exactly. Barchart (citing Crane Data) and The Chart Report independently confirm the $8.28 trillion record. ICI's weekly money market fund assets release (dated 6/3/2026) is the underlying primary data source for that week. While the exact $66B weekly inflow and $41B one-day figures were not individually verified at the granular ICI release page, the overall claim and key headline number are consistent across the primary data ecosystem (ICI/Crane Data).
