REBEKAH MERCER

Rebekah Mercer grew up the daughter of Robert Mercer, a brilliant computer scientist who became co-CEO of Renaissance Technologies, one of the most successful hedge funds ever. She studied biology and math at Stanford, then worked briefly as a trader at her father's firm.

But trading was not her thing. Politics was.

She took over the Mercer Family Foundation and turned it into a funding engine for conservative causes. She put money into the Government Accountability Institute, the think tank behind the book Clinton Cash.

She backed Breitbart News. In 2016, when the Trump campaign was floundering, she helped engineer the move that brought in Steve Bannon and Kellyanne Conway.

Then she went quiet again and kept writing checks.

Her family money comes from Renaissance Technologies, the secretive quant fund her father helped run. Rebekah herself is better understood through what she funds.

She co-founded Parler in 2018, a free-speech social network that exploded in popularity then got cut off by Apple, Google, and Amazon after the Capitol riot. She was an early backer of Cambridge Analytica, the data firm that harvested Facebook profiles and later collapsed in scandal.

More recently she became a partner at 1789 Capital, a venture fund built around anti-woke, parallel-economy companies. That fund put money into Trump Media.

The thread is consistent. She invests in ideas and infrastructure, not just stocks.

Mercer does not think like a stock picker. She thinks like a venture capitalist for politics.

The idea is simple. Find an underfunded movement or platform, pour money in early, and try to bend the culture.

She is willing to back fringe ideas that polite money avoids. Parler and Breitbart were both bets that mainstream platforms had left a huge audience unserved.

Sometimes that works. Often it explodes.

Basically, she treats political and cultural change like a startup portfolio. Plant a lot of seeds, accept that most die, and swing for the one that reshapes everything.

Her biggest win was 2016. When Donald Trump's campaign was sputtering that summer, the Mercers were among the donors who pushed to install Steve Bannon as campaign chief and Kellyanne Conway as manager.

Trump won. For a relatively small political bet compared to the establishment Republican machine, the Mercers got enormous influence over a presidency.

Rebekah landed a spot on the Trump transition team. In pure return-on-influence terms, it was one of the best political bets of the decade.

Parler. Mercer reportedly sank tens of millions into the free-speech social network.

For a while it was the most downloaded app in America. Then January 6, 2021 happened.

Within days, Apple and Google pulled it from their stores and Amazon kicked it off its servers. The app went dark.

She forced out co-founder John Matze in the fallout. Parler limped along and was eventually sold and shut down in its original form.

The lesson she learned the hard way is that building on someone else's infrastructure means they can pull the plug. It is a brutal lesson, and it cost her a fortune.

Mercer's guiding belief is that money should buy long-term influence, not short-term comfort. She funds institutions, not headlines.

Her view is that culture and ideas move slowly, so you have to be patient and keep paying. She also believes the mainstream gatekeepers cannot be trusted, which is why she keeps funding alternatives to them.

In a rare 2017 op-ed she wrote that open discourse and vigorous, reasoned debate have been fundamental to America's success. Whether her platforms delivered that or the opposite is the debate that follows her everywhere.

Rebekah is one of Robert Mercer's three daughters. The sisters are sometimes called the Mercer girls in the press.

She married Sylvain Mirochnikoff, a French-born banker who became a managing director at Morgan Stanley, in 2003. They met at Stanford.

They have four children and live in New York, keeping family life almost completely private. Her father Robert stepped back from Renaissance in 2017 amid the political controversy the family attracted.

The Mercers are a tight, private clan that lets its money do the talking.

Rebekah Mercer studied at Stanford University, earning a dual bachelor's degree in biology and mathematics. She went on to a master's in operations research and engineering from Stanford in 1999.

The math and science training is real, which makes her later funding of climate-skeptic groups one of the more puzzling parts of her story.
