Bloomberg estimated in August 2026 that Grant LaFontaine and co-founder Logan Head each own a stake in Whatnot worth more than $2.8 billion. The estimate came as Whatnot raised a $545 million Series G at a $20 billion valuation on 7 August 2026.
Whatnot is unlisted and has announced no IPO as of November 2026. The stake has not been sold, so the figure moves with the company's valuation.
The valuation has climbed fast. Whatnot raised $265 million at about $5 billion in January 2025 and $225 million at $11.5 billion in October 2025. Live sales passed $8 billion in 2025, and first-half 2026 sales exceeded all of 2025, the company said.
LaFontaine grew up in Maine, sold Pokemon cards as a child and opened an eBay store in fourth grade. Whatnot began in 2019 as a Funko Pop marketplace and added live video in 2020.
