Ackman calls Microsoft impossible to disrupt with 450 million locked-in users and safe Copilot AI.

Ackman views $MSFT as having an “impossible to disrupt” position in enterprise software. The base Microsoft 365 package has 450M users at a very low cost per seat, roughly $200 per customer. It would be nearly impossible for an enterprise to replace these various components with 3P vendors, even at twice the price.

Microsoft Copilot gives enterprise employees a secure way to access AI tools without putting the company at risk of extreme cloud computing bills or exposing proprietary data.
