1. Portfolio Overview

The most striking feature of 12 West Capital Management’s Q3 2025 filing is the dramatic reduction in portfolio size.

2. Key Holdings

GDS Holdings (GDS) remains the dominant position, despite a reduction in stake. It accounts for 35.73% of the portfolio ($175.00M).

This suggests continued confidence in the data center infrastructure theme, likely driven by AI demand, even while taking some profits or managing portfolio risk.
