Lululemon founder Chip Wilson’s $6.1 billion fortune could take a big hit in his no-prenup divorce — with marital gains potentially subject to a 50-50 split, top Canadian divorce lawyers told The Post.
Wilson, 71, and Shannon “Summer” Wilson, 52, got hitched in 2002 and are now embroiled in a divorce proceeding in British Columbia.
A family-law case involving the couple was opened in April in the province’s Supreme Court, though the the contents are not publicly available, according to Bloomberg News.
Still, it seems clear that the athleisure mogul could have a painful payout in store.
“In British Columbia, the value of assets brought into the marriage is not shareable, but the gain is called family property and presumptively divided 50-50,” Lorne MacLean KC, founder of Vancouver-based MacLean Law, told The Post on Monday.
Vancouver divorce attorney and arbitrator Georgialee Lang separately told The Post that the absence of a prenup could have major consequences for how the couple’s property is divided.
“Without a prenup, his wife is entitled to 50% of family property. Family property is defined as all property owned by a spouse,” Lang told The Post.
“However, if he can prove that he brought certain assets into the marriage or their initial cohabitation, if any, Chip will be able to retain the value of the pre-owned assets at the date he brought them it into the relationship at that date’s value,” she added.
“The increase in value from the time he brought the property into the relationship is shared equally by the parties based on current values.”
That distinction could loom large for Wilson, who founded Lululemon in 1998 — four years before he and Summer tied the knot.
Forbes currently places his fortune at $4.9 billion, while the Bloomberg Billionaires Index puts it at $6.1 billion.
The eventual division of the Wilsons’ property remains unknown, and the sealed proceeding makes it impossible to determine which assets either spouse is claiming as family property or what valuations they may put on them.
Chip’s sprawling holdings include a nearly $3 billion position in Amer Sports, whose portfolio includes Arc’teryx, Salomon and tennis equipment company Wilson, along with a major interest in Lululemon and extensive real-estate investments.
The 71-year-old billionaire is one of Lululemon’s biggest shareholders more than a decade after leaving the company.
Recent securities filings show he and affiliated family entities controlling roughly 8.7% of Lululemon, a block that was recently valued at just under $1 billion.
That figure includes shares attributed to Summer and the family’s charitable foundation, meaning the entire stake cannot be counted as Chip’s personal holdings.
The Wilsons’ marriage has intertwined business and family interests.
Summer was Lululemon’s founding lead designer and helped create some of the company’s early products. The couple are also co-founders of House of Wilson, their family office, and established the Wilson 5 Foundation in 2012.
They have a blended family of five sons, including three sons together.
A September securities filing attributes 1,092,596 Lululemon shares, or about 1%, to Summer under beneficial ownership rules.
But only 268,984 exchangeable shares are held directly by her, while 823,612 shares are directly owned by the Wilson 5 Foundation.
At Lululemon’s recent $100.61 share price, Summer’s directly disclosed position was worth roughly $27 million, while the entire beneficial ownership block was worth about $110 million.
Chip also has substantial real-estate holdings through his family office, including Low Tide Properties, whose portfolio spans Vancouver and the Seattle area.
Forbes estimated in 2024 that Chip’s interest in Low Tide’s then-portfolio, together with his Vancouver mansion, was worth roughly $500 million.
Chip’s waterfront Vancouver home received a $53 million assessment for 2026.
A separate appeal this year reduced the property’s assessment for the prior roll from roughly $60 million to around $47 million.
Splitting family property may not be the end of Wilson’s financial exposure, MacLean said.
“Spousal support in Canada is generous and large awards are often made in high net worth cases before trial and even after a substantial Family property division award has been made,” MacLean told The Post.
The Post has sought comment from the House of Wilson and Lululemon.
