Chip Wilson, the 71-year-old billionaire who built Lululemon Athletica into an $11 billion athleisure empire, is divorcing his wife of more than two decades without a prenuptial agreement, a split that could reshape one of Canada's largest personal fortunes.

Wilson and Shannon "Summer" Wilson, 52, have ongoing family litigation in British Columbia Supreme Court, where court files are sealed, the New York Post reported. The couple married in 2002. Bloomberg, citing two people familiar with the Wilsons' conversations, first reported that no prenuptial agreement exists between them.

The absence of a prenup is the detail that turns a private family matter into a financial story worth watching. Chip Wilson's net worth sits at $6.1 billion. He holds an 8.6 percent stake in Lululemon worth nearly $1 billion. Shannon Wilson, who served as the company's founding lead designer and later founded the luxury retail brand Kit and Ace, holds roughly a 1 percent stake valued at approximately $100 million.

Under Canadian family law, the division of assets accumulated during a marriage can be extensive, and without a prenup, the negotiation starts from a very different baseline than it would in a jurisdiction where one spouse's pre-marriage wealth is clearly ring-fenced. The sealed court files mean the public knows almost nothing about the terms being contested.

A partnership that built an empire, and ended quietly

Shannon Wilson was not a bystander in Lululemon's rise. She was one of the company's first hires and its founding lead designer. Chip Wilson himself credited her with playing "a huge part" in growing Lululemon into the brand it became. Both left the company more than a decade ago.

Chip Wilson stepped down as chairman of the board in 2013 after a string of public gaffes. The most memorable came during a recall of yoga pants that turned out to be sheer enough to reveal women's rears. Wilson blamed the customers, not the product.

"Quite frankly, some women's bodies just actually don't work for [the pants]."

That remark accelerated his exit from the company's leadership. But Wilson never stopped having opinions about the brand he built.

In a 2024 Forbes interview, he criticized the direction Lululemon had taken, arguing the company had lost its identity. He slammed its "whole diversity and inclusion thing" and blasted the use of "unhealthy" and "sickly" people in advertisements, calling them "not inspirational."

Wilson told Forbes:

"I think the definition of a brand is that you're not everything to everybody. You've got to be clear that you don't want certain customers coming in."

He said the chain had "become like the Gap, everything to everybody."

December 2025 proxy fight signaled Wilson wasn't done

Wilson's frustration with Lululemon's leadership boiled over into a proxy battle in December 2025. He called the company's leadership "complacent" amid declining sales. The outcome of that fight was not detailed in public reporting. But the timing matters: family litigation was first filed in British Columbia Supreme Court in April, just months after Wilson waged a public corporate battle while his marriage was apparently unraveling behind sealed court doors.

Born in the United States and raised in Canada, Wilson built his fortune from scratch. That fortune now faces a legal process that, without a prenup, could produce one of the largest divorce settlements in Canadian history, though no terms or proposed divisions have been made public.

High-profile splits involving enormous wealth and no prenuptial agreement have a way of becoming prolonged, expensive, and public, regardless of how tightly the court files are sealed at the start. Relationship drama among the wealthy and powerful rarely stays quiet for long.

Neither side has spoken publicly

Neither Chip Wilson nor Shannon Wilson has publicly confirmed or commented on the divorce or the reported absence of a prenuptial agreement. The sealed status of the British Columbia Supreme Court files means the specific grounds, claims, and any proposed asset division remain unknown.

Bloomberg's reporting relied on two unnamed people familiar with the couple's conversations, a thin sourcing chain for a claim with billions of dollars in implications. Whether that detail holds up, or whether some other financial arrangement exists between the Wilsons, remains an open question.

What is clear: a man worth $6.1 billion, who spent decades building a company alongside the woman he married, is now dividing that life in court, reportedly without the one document that would have made the math simpler. Twenty years of marriage, an $11 billion brand, and no prenup. The lawyers on both sides of this case will not be working cheap.
