1. Pershing Square Boosts Amazon Position
Pershing Square increased its Amazon stake by 3.78 million shares during Q4 2025, bringing its total holdings to 9.61 million shares valued at over $2.22 billion. This makes Amazon the fund’s third-largest position, following an initial investment established in April 2025 amid tariff-driven volatility.

The number of hedge funds holding Amazon rose to 381 from 332, pushing combined positions to $88.7 billion, up from $73.35 billion.
