Comprehensive Analysis of Marex Group plc SEC 13F Filing (Q3 2025)
1. Portfolio Overview

Marex Group plc reported a significant contraction in portfolio value for the quarter ending September 30, 2025, with total assets under management (AUM) decreasing by 23.1%, falling from $11.53 billion to $8.86 billion.

2. Key Holdings

The portfolio is dominated by high-conviction positions in leading technology and consumer cyclical firms. Tesla Inc. (TSLA) is the single largest holding, comprising 14.59% of the portfolio ($1.29B), indicating a strong bet on the electric vehicle and energy sector. Mastercard (MA) and Booking Holdings (BKNG) represent the top financial and industrial positions, respectively, highlighting exposure to the travel recovery and digital payments sectors.

A notable feature of the top holdings is the dual allocation to spot Bitcoin ETFs. The COINSHARES BITCOIN ETF and ISHARES BITCOIN TRUST (IBIT) occupy the 6th and 8th spots, respectively, combining to form a roughly 12% allocation to digital assets. This suggests an institutional embrace of cryptocurrency as a distinct asset class. The technology sector is further represented by heavyweights such as NVIDIA (NVDA) (6.40%) and Netflix (NFLX) (5.67%), signaling a focus on AI infrastructure and streaming dominance.
