Bill Ackman Q1 2026 Portfolio Update: Major Shifts in Amazon, Microsoft Holdings

For the quarter ending March 31, 2026, Bill Ackman's Pershing Square Capital Management saw significant shifts in its portfolio holdings. The analysis of the disclosed top holdings reveals a clear pattern of strategic adjustments, with substantial increases in some stocks and decreases in others.

Amazon (AMZN) stands out as the most significant addition during this period. Ackman's position in the e-commerce giant grew substantially, with an increase of 1,919,883 shares, representing a nearly 19.19% increase in the position's share count from the previous quarter. This translates to a significantly larger allocation within the portfolio, now accounting for 17.39% of the total value.

Microsoft (MSFT) also saw a major boost, with a 100% increase in shares held during the quarter. Ackman acquired 5,654,078 shares, establishing a new position that now represents a substantial 15.26% allocation in the portfolio.

Conversely, several existing holdings experienced reductions. UBER (UBER) saw its position decrease by 0.82%, with a reduction of 248,963 shares. The allocation for this ride-hailing company dropped to 15.71% of the portfolio. Similarly, BROOKFIELD CORP (BN), a holding in the Financial Services sector, decreased by 2.78% in shares, resulting in a reduced allocation to 17.62%. Restaurant Brands International (QSR) also faced a reduction, with a 0.97% decrease in shares, lowering its portfolio allocation to 12.2%. META (META) experienced a small but notable reduction, with a 0.48% decrease in shares, bringing its allocation down to 11.1%.

Two other holdings showed significant declines. Alphabet's GOOG unit saw a staggering 94.94% reduction in shares, effectively liquidating a substantial portion of that position, leaving only a negligible 0.65% allocation. The GOOGL position also faced near-total liquidation, with a 95.23% reduction, resulting in a tiny 0.07% allocation.

It's important to note that the data provided does not include previous period allocations for all holdings, making it impossible to definitively confirm if any positions were fully exited during this quarter. However, the near-total reduction of the GOOG and GOOGL positions suggests a significant unwinding of those specific investments.
