Top Investors Converge on Amazon, Alphabet, and Uber
When Q1 2026 13F filings were released in mid-May, three companies kept surfacing across the sharpest institutional portfolios: Amazon (AMZN), Alphabet (GOOGL), and Uber (UBER). Bill Ackman's Pershing Square disclosed Amazon as roughly 17.4% of the portfolio and Uber at 15.7%. David Tepper's Appaloosa added to both Amazon (~15.2%) and Uber (~7.7%), while slightly trimming Alphabet to roughly 8%. Li Lu's Himalaya Capital ran Alphabet at ~44.8% combined between GOOGL and GOOG, and Warren Buffett's Berkshire Hathaway more than doubled its Alphabet stake to roughly 6% of the portfolio.
Ackman and Tepper see Amazon as an 'AI Cash Machine' with a $200 billion capex plan being redeployed into AI infrastructure. The company traded around $273.86 on Aug. 6, up nearly 21% year to date and tracking their thesis. Q1 2026 revenue rose 16.6% to $181.52 billion, and EPS of $2.78 beat expectations of $1.65.
Alphabet is the 'Value Play' that Buffett and Li Lu both see, with shares up 14.09% YTD and 83.36% over one year, yet the forward P/E sits at just 26. Q1 2026 EPS of $5.11 beat expectations of $2.53.
Uber is the outlier, with shares down 16.68% YTD and 22.62% over the past year, but Ackman and Tepper both hold it. Why? Q1 2026 gross bookings rose 25% to $53.72 billion, Uber One hit 50 million members driving half of gross bookings.
