No higher bid in the 90‑day window
Musk’s offer of $54.20/share (about $44B) was accepted by Twitter’s board on April 25, 2022. Contemporary coverage notes that “no other bidders or white knights” emerged during the sale process before the board agreed to Musk’s deal, and analysts explicitly highlighted that the board’s “back was against the wall” because no rival offer appeared. (forbes.com) This matches Chamath’s claim that in the ensuing 90 days there would be no better bidder/offer.

Board initially resisting the bid
Right after Musk’s bid, Twitter’s board unanimously adopted a shareholder‑rights “poison pill” designed to dilute Musk and make a takeover prohibitively expensive, widely described as blocking or thwarting his takeover attempt. (pbs.org) This is an initial attempt to fend off/reject the bid, even though the board reversed course and approved the merger about 10 days later. Factually, the “first try to reject it” part of the prediction is borne out.

Shareholder lawsuits and years of litigation
Within weeks, a Twitter stockholder (the Orlando Police Pension Fund) filed a putative class action in Delaware Chancery Court against Twitter, its board, and Musk, alleging breach of fiduciary duty and seeking to delay or constrain the merger under Delaware law. (cdn.yahoofinance.com) Additional stockholder litigation followed, including Crispo v. Musk, a class action by a Twitter stockholder over enforcement of the merger agreement; the Delaware Court of Chancery issued opinions in 2022 and again in 2023, showing that stockholder litigation over the deal persisted well beyond closing.

After the acquisition closed and Twitter became X Corp., further lawsuits tied to the deal and its aftermath continued for years—e.g., large‑scale disputes over severance and layoffs of former employees and a major severance suit by former top executives, as cataloged in the running list of lawsuits involving X Corp. and in later federal cases, many of which remained active into 2024–25. (en.wikipedia.org) While not all of these suits are by common shareholders or solely about the board’s initial resistance, they confirm that Twitter/X was indeed embroiled in extensive litigation for years stemming from the Musk takeover.

Putting these pieces together: (1) no superior bid emerged in the 90 days after April 16, 2022; (2) the board initially tried to block the bid via a poison pill before accepting it; and (3) shareholder and related litigation over the deal and its consequences has dragged on for multiple years. That aligns closely enough with Chamath’s forecast that the overall prediction is best judged as right.
