Bill Ackman reveals new Microsoft stake, funded by Alphabet sale
Pershing Square Capital founder Bill Ackman said he opened a Microsoft position during the first-quarter sell-off. He funded the trade by exiting his Alphabet stake.

Pershing Square Capital Management founder Bill Ackman said Friday on X that his fund built a significant Microsoft position during the first quarter of the year. Ackman said the buying took place during the early-2026 tech sell-off.
He added that the purchase was funded by exiting Pershing Square's Alphabet stake, stressing the sale was not a bet against the company. Ackman cited Microsoft's positioning in artificial intelligence and cloud computing as the basis for the long-term thesis.
The disclosure came after the Dow fell more than 500 points on Friday amid a broad tech retreat. Pershing Square had held Alphabet shares for several years, and Microsoft now stands as the fund's largest technology bet, according to filings.
