Financial forums are buzzing today as the latest 13F filings roll in, and as always, all eyes are on Pershing Square. Bill Ackman has built a reputation on high-conviction, concentrated bets, and his latest activity suggests he’s not just sitting on his laurels. Whether you're a value investor or a macro swing trader, there’s plenty to digest here.
The current Bill Ackman portfolio remains one of the most concentrated in the game, dominated by companies with massive moats. As of the Q4 2025 data, Brookfield Corporation ($BN) has claimed the top spot, making up a staggering 18.15% of the total holdings.
What’s interesting is the sheer weight of "Big Tech" that Ackman is now carrying. For a guy who made his bones in retail and fast food, seeing Uber ($UBER) at nearly 16% and Amazon ($AMZN) at over 14% (following a massive 65% increase in his position this quarter) tells us he is chasing growth and platform dominance more than ever before.
The "New Buy" Everyone is Talking About: Meta Platforms
The biggest shocker in the latest update is a massive New Buy in Meta Platforms ($META). Ackman has entered the position with a weight of 11.37%, instantly making it one of his top five holdings. This isn't a small "toe-dip"—this is a statement. Clearly, Pershing Square believes the AI-driven monetization at Meta still has significant runway left in 2026.
Trimming the Fat: Alphabet and Hilton
It’s not all buying, though. Ackman appears to be rotating out of his secondary Alphabet ($GOOGL) position, which saw a -86% reduction in one of his share classes. While he still holds a massive $1.93 billion stake in Alphabet overall, this strategic trim suggests he might be reallocating that capital into the newer Meta bet.
We also saw a very slight decrease in Hilton Worldwide ($HLT) and Restaurant Brands International ($QSR). These are his "legacy" winners, and while he’s not exiting, the -0.21% trims across the board suggest he is keeping these positions on a tight leash.
Ackman isn't just playing the market; he’s playing for dominance. By piling into Amazon and Meta while holding steady on infrastructure giants like Brookfield, he’s creating a barbell strategy: rock-solid assets on one side, and aggressive tech growth on the other.
