Whatnot raises $545M at $20 billion valuation in Series G

Whatnot raises $545M in a Series G financing that values the live-commerce marketplace at $20 billion, according to reports from Quartz and Fortune. ICONIQ, Lightspeed and Avra led the round, which takes the company’s valuation close to twice the $11.5 billion level set in an October 2025 Series F.

The company said the money will go toward seller tools, more AI features in the selling experience, expansion into new markets, buyer growth, and trust and safety. It is a large private-market vote on a consumer marketplace business that began with collectibles and now competes for sellers across broader retail categories.

Whatnot said it has raised about $1.5 billion since its 2019 founding. The reporting reviewed here does not provide revenue, profitability, burn, or ownership figures for the new financing.

What will Whatnot spend the $545M on?

Whatnot’s stated priorities put international growth and marketplace operations alongside product development. The company runs livestreams in which sellers offer goods through auctions and fixed-price transactions, making seller tooling and trust controls central to the product rather than peripheral administrative work.

Its AI plans remain broadly described. Whatnot has said it will bring AI to more of the selling experience, but the available reporting does not specify particular products, deployment timing, or the effect expected on seller economics or moderation.

For founders and employees, the $20 billion figure is a financing price, rather than a complete measure of operating performance. Startup valuation determines the price of new shares and raises the operating expectations for the next round or eventual public listing.

How does the new valuation compare with Whatnot’s prior round?

The new valuation is $8.5 billion above the $11.5 billion valuation reported after Whatnot’s $225 million Series F in October 2025. That is an increase of roughly 74%, close to but short of a doubling. Fortune also reported that CapitalG has led three earlier Whatnot rounds, including its 2021 Series C, which raised $150 million at a $1.5 billion valuation.

New investors named in the Series G include Kleiner Perkins, Wellington Management and Standard Capital. Returning backers include Andreessen Horowitz, BOND, DST Global, Greycroft, Y Combinator and CapitalG, according to Quartz and Fortune.

Whatnot’s reported growth and competitive pressure

Whatnot said it had already exceeded its full-year 2025 gross merchandise volume, had more than 650,000 people signing up each week, and had more than doubled the number of sellers with over $1 million in lifetime sales during the previous year. Those are company-reported metrics, not independently verified results in the available reporting.

The company has expanded from collectibles into categories including fashion, electronics, beauty and fresh food. Its better-known competitors include eBay, Fanatics and TikTok Shop Live. Fortune has also reported concerns that Whatnot may encourage gambling-like excessive spending. Whatnot told Fortune it bans gambling-style activity, including raffles and lotteries, through seller requirements and other controls. The new capital gives the company more room to grow, while keeping the burden on Whatnot to show that higher transaction volume can coexist with effective marketplace safeguards.
