Day brief
Net regulatory AUM fell by $2.1B across the advisor landscape on September 28, 2026, as a massive deregistration offset strong gains among expanding firms. Madison Capital Partners headlined the day's downward pressure with a $4.8B exit, overshadowing a combined $2.6B added by reporting winners.
Xcelsior Advisor Partners LLC led all advancers, jumping $1.9B (+285.8%) to lift its regulatory AUM from $650.7M to $2.5B. Abbey Capital Limited also saw sizable growth, climbing $766M (+11.2%) to reach $7.6B from a previous baseline of $6.8B.
The overall contraction was driven by two deregistrations totaling $4.8B in departing AUM, with Madison Capital Partners representing the entire reported figure at $4.8B. Zero firms reported asset declines during the period.
