One possibility is teaming with private-equity firm Silver Lake Partners, which was planning to co-invest with him in 2018 when he was considering taking Tesla private, and whose Co-CEO Egon Durban is already a Twitter board member and led Musk's deal team during the 2018 failed effort to take Tesla private, sources said. Silver Lake declined to comment.

Whether Musk would present Twitter with an entirely new offer — perhaps raising his current bid — or whether new partners would simply go in on a purchase with him isn't clear. A Musk spokesperson declined to comment.

As we predicted earlier (see below), one way to circumvent Twitter's Poison Pill is for Musk "to be joined by one or more like-minded, anti-censorship investors such as Peter Thiel who either build up stakes through the poison pill 15% limit in the process making a management and board replacement by proxy vote the simple outcome." And indeed, the Post writes now that the "pill may not stop other entities or people from acquiring their own shares of up to 15% of the company. Those owners could partner with Musk to force a sale, make changes in the executive ranks or push for other overhauls of the company."

"This is not over," a source close to the situation told the Post.

It sure isn't because separately, Bloomberg, Reuters and the Post all report that besides Musk's offer, Twitter has been fielding takeover interest from other parties, including technology-focused private equity firm Thoma Bravo, which is considering making a rival offer. The New York Post reported Thoma Bravo's interest on Thursday.
