The billionaire investor William Ackman appears to have scaled back his ambitions for an initial public offering in New York — at least in terms of its size. The investment vehicle that Mr. Ackman plans to take public on the New York Stock Exchange next week — Pershing Square USA — is aiming to raise $2 billion in the share sale, according to a regulatory filing on Tuesday. That’s a far cry from the $10 billion or more that Mr. Ackman discussed as a target earlier this year. In investor meetings in recent months, he had floated an even larger number: $25 billion. The $2 billion figure is a place holder, and Pershing Square USA could raise more as investors put in orders through Monday night, according to a person familiar with the deal who spoke on the condition of anonymity because the details were private.
