Profiles in Power: Who Is Bill Ackman? The Hedge Fund Billionaire Who Fired a University President, Then Attacked the Journalists Who Covered His Wife

Bill Ackman would like you to know he is not a bully. He has said this explicitly, on X, in long posts that run several thousand words, multiple times.

What he is, by his own description, is someone who 'pays attention to the facts and sees where they take him.'

The facts, in his telling, led him to orchestrate a campaign to remove the president of Harvard University, demand the firing of the presidents of MIT and Penn, threaten to sue a media outlet that published reporting on his wife, launch a systematic plagiarism review of MIT's entire faculty, and post thousands of words of invective on social media at people who disagreed with him, often in the middle of the night.

Not a bully. Just very concerned.

Who he is

Bill Ackman is the founder and CEO of Pershing Square Capital Management, a hedge fund he started in 2004. He is of Ashkenazi Jewish descent, earned both his undergraduate and MBA degrees from Harvard, and has donated millions to the university over his career.

He became famous, or infamous depending on your vantage point, for a series of high-conviction, high-aggression bets: a $1 billion short against Herbalife that he maintained for years in the face of massive losses before finally closing, a crushing loss on Valeant Pharmaceuticals, and a highly profitable bet against the market early in COVID-19.

His investing style is activist. He buys large stakes in companies, goes public with demands, and applies relentless pressure until management changes.

His net worth is estimated at around $4 billion. He is, in the classic sense, a man who wins by making his target's continued resistance more painful than capitulation.

He appears to have decided that universities respond to the same playbook.

The Harvard campaign

On October 8, 2023, one day after the Hamas attack on Israel, a coalition of Harvard student groups signed a letter holding Israel 'entirely responsible' for the attack. Harvard's official response was that student groups speak for themselves, not the university.

Ackman, a significant Harvard donor and self-described proud alumnus, sent a 3,000-word letter to Harvard president Claudine Gay demanding a stronger institutional condemnation.

When Gay testified before Congress in December 2023, alongside the presidents of MIT and Penn, and gave legalistic answers about whether calls for genocide against Jewish students would violate campus policies, the backlash was immediate and bipartisan.

Ackman led the charge. He amplified plagiarism allegations against Gay. He coordinated with other wealthy donors. He posted constantly.

The University of Pennsylvania president resigned within four days of the testimony. Gay initially survived, but resigned on January 2, 2024, after six months in office, the shortest tenure in Harvard's history.

Gay, in a New York Times essay after her resignation, wrote that the campaign against her was about more than one university and one leader. She was the first Black president in Harvard's 388-year history.

The part where it gets revealing

While Ackman was leading the anti-DEI charge at universities, framing his campaign as a defense of academic integrity and Jewish student safety, Business Insider published two pieces finding that his wife, architect and MIT alumna Neri Oxman, had instances of plagiarism in her own academic work.

Ackman's response was to threaten to sue Business Insider. He called the reporting a 'hit piece.' He demanded the articles be retracted. He posted thousands of words attacking the publication's credibility and ownership.

He thanked Elon Musk for his support. He launched a systematic plagiarism review of MIT's entire faculty and board, apparently to demonstrate that everyone has some plagiarism if you look hard enough, and therefore his wife's was not meaningful.

To be clear: Ackman spent months insisting that plagiarism in academic work was a disqualifying offense that proved Claudine Gay was an unqualified DEI hire. Then, when the same standard was applied to his wife, it became a politically motivated hit job.

He has not apparently noticed the contradiction. Or he has and doesn't care.

What this is actually about

Ackman is not the most powerful person in this series. He does not have Musk's government access or Thiel's infrastructure or Griffin's market position. What he represents is something slightly different: the willingness to use private wealth as a direct weapon against institutions that produce inconvenient outcomes.

He didn't lobby Harvard through normal channels. He didn't write an op-ed and wait. He coordinated with other wealthy donors to make it financially painful for the institution to resist. He used a media platform to amplify pressure. He made the board calculate that keeping Gay was more expensive than removing her.

That is not civic engagement. That is the same activist investor playbook he uses on publicly traded companies, applied to academic governance.

This model, where a billionaire donor uses financial leverage to dictate outcomes at nominally independent institutions, is not unique to Ackman. But he was unusually public about it, which makes him a useful case study in how it actually works.

Universities, newspapers, cultural institutions: these are all now legible to a certain class of wealthy person as pressure points. Not because they control them directly, but because the institutions need the money, and the money comes with opinions.

He's not a bully. He just pays attention to the facts. Oh yeah, he's also a professional tennis player..lol

Stay Frustrated.
