Pershing Square Tontine Holdings, a special purpose acquisition company formed by Bill Ackman to acquire "mature unicorns," filed for a $3 billion IPO.
Why it matters: $3 billion would be the most money ever raised by a SPAC. And it may ultimately raise nearly $6.5 billion, based on concurrent plans to raise between $1 billion and $3 billion from funds associated with Ackman's hedge funds, plus up to another $450 million if banks exercise their over-allotment options.
- Mature unicorns? Yeah, we need a better term for this. Twitter is helping out.
- The backdrop: Pershing Square did a SPAC back in 2011, which ultimately took Burger King public.
The bottom line: "The deal will give Ackman firepower to compete for a big acquisition against some of the largest private equity firms, such as Apollo Global Management and The Blackstone Group," writes Reuters.
