Ackman, Loeb take different routes on tech bets in early 2026

Billionaire investors Bill Ackman and Daniel Loeb took divergent tech positions in early 2026, according to regulatory 13F filings. Ackman’s Pershing Square began building a new stake in Microsoft after February weakness, arguing the market underappreciates Microsoft 365 and its AI investments; Microsoft shares were up ~3% on the day. By contrast, Loeb’s Third Point liquidated a long-held Microsoft stake, selling 925,000 shares in Q1. The two also traded positions in Alphabet—Ackman trimmed and then exited most of his holding while Third Point bought 175,000 shares—and both established new Q1 positions in Meta Platforms. The filings underscore selective institutional positioning within the “Magnificent Seven” AI leaders and could influence flows and sentiment around large-cap tech names.
