Sacra estimates Whatnot generated $359M in revenue in 2024, up 102% YoY, with the platform achieving $3B in GMV that year. The company generated roughly $1B in revenue in 2025, consistent with $8B in full-year GMV—more than doubling 2024's total. The company's core revenue comes from its marketplace take rate, charging sellers an 8% commission in the US (6.67% in UK/EU) plus a 2.9% + $0.30 payment processing fee per transaction.

Whatnot's fastest-growing categories by GMV in 2025 were Beauty (+791% YoY), Electronics (+444% YoY), Jewelry (+259% YoY), and Women's Fashion (+223% YoY), with fashion buyers placing 12M+ orders per month. The platform ranked #1 Shopping app in both the U.S. and U.K. in 2025, spending 144 days in the App Store top 20, and generated $100M+ in live sales during Black Friday 2025 alone. Engagement metrics have strengthened materially: users spend an average of ~95 minutes per day on the platform, month-over-month customer retention has improved to over 80%, and new buyers grew 285% over the year.

Over 500 sellers have achieved $1M+ in annualized sales, and 1 in 8 sellers are now full-time, up 20% YoY. Despite strong GMV growth, the company remained unprofitable as of mid-2025. Recent revenue diversification efforts include the launch of advertising products in 2023, starting with boosted livestreams, which has pushed the overall take rate from 12% toward 12.5%. Despite growing competition from TikTok Shop's aggressive 6% commission rates, Whatnot's combination of entertainment and commerce continues to drive strong marketplace dynamics and revenue growth.

In October 2025, Whatnot announced it had raised $225M at an $11.5B valuation, bringing total funding to ~$968M. The round was co-led by DST Global and CapitalG and included up to $126M in secondary for existing shareholders.

Whatnot was previously valued at $4.97 billion in its Series E funding round in January 2025, when it raised $265 million.

Investors across rounds include Greycroft, DST Global, Andreessen Horowitz, Avra, Lightspeed Venture Partners, and Durable Capital.

Whatnot was founded in 2020 by Grant LaFontaine and Logan Head, initially launching as a marketplace focused on Funko Pop collectibles trading.

Whatnot found product-market fit as a livestream shopping platform for collectible enthusiasts, particularly those interested in trading cards, toys, and rare items. The platform merged the engagement of live video with the thrill of collecting, allowing sellers to showcase their items in real-time while building personal connections with buyers.

The core product enables sellers to host live video auctions where they can display, discuss, and sell items to an engaged audience. Sellers can conduct "breaks" where multiple buyers split the contents of unopened card packs, run mystery box openings, or showcase individual items for auction or immediate purchase. Buyers participate through live chat, place bids, and make instant purchases during streams. Shows with strong pre-bid activity see up to 7x more total sales and nearly 4x more orders than shows without it.

Beyond live auctions, Whatnot offers traditional marketplace listings and two newer formats across a rapidly expanding catalog of categories: Auctions (asynchronous bidding outside of live shows, initially launched in categories like Sports Cards) and Video Listings (shoppable video content attached to static listings). The platform has expanded into 35+ new categories, including Beauty, Electronics, Jewelry, and a Wholesale vertical that reached $1.5M in weekly sales shortly after its launch. In the luxury segment, Whatnot runs "Bagged & Verified," a pre-authentication program for Luxury Bags & Accessories developed in partnership with Entrupy and Real Authentication that offers sellers discounted authentication at $7–$10 per item. Whatnot has also taken the platform international, expanding into Australia where hundreds of shows have crossed $10K in sales. Each seller essentially operates their own micro-channel, building a following of collectors who share their specific interests.

Whatnot is a livestream shopping marketplace that connects collectors and enthusiasts with sellers through interactive video commerce, primarily focused on collectibles, fashion, and luxury items. The platform generates revenue through a transaction-based model, charging sellers an 8% commission on most sales plus a 2.9% + $0.30 payment processing fee per transaction.

The platform offers category-specific commission structures to drive adoption in strategic verticals, with reduced rates for coins (4%) and electronics (5%). For high-value items, Whatnot waives commissions on portions of sales exceeding $1,500 to attract luxury sellers.

Whatnot's competitive advantage stems from its entertainment-driven commerce model, which generates 10x more transactions than traditional peer-to-peer marketplaces. The platform's livestream format creates strong buyer-seller relationships, with 62% of sellers remaining exclusive to Whatnot despite competition from TikTok Shop and others.

The company employs a product-led growth strategy by expanding into adjacent categories like fashion, luxury, and wholesale while maintaining its core collectibles focus. Recent initiatives like the Rewards Club program drive buyer retention and increase seller engagement, with beta tests showing 12% higher spending per buyer and 20% more repeat purchases. Whatnot has also begun diversifying revenue through advertising products, including boosted livestreams and show promotions, which increase the platform's effective take rate beyond its headline 12.5%.

Seller accountability has tightened alongside scale. Sellers now bear refund liability for late U.S. domestic shipments without confirmed drop-off, and Account Health scoring incorporates in-app scanner and Whatnot Manifest signals to enforce fulfillment standards—measures that strengthen buyer trust while adding cost discipline for sellers.

Whatnot operates in a market that includes traditional resale marketplaces, livestream commerce platforms, and vertical-specific marketplaces for collectibles and fashion.

eBay dominates with $75B in annual GMV and recently removed seller fees for private sellers in some markets. Depop ($550M GMV) and Vinted ($10B+ GMV) focus on fashion resale with no seller commissions, instead generating revenue primarily through buyer fees and services. Back Market (€2.16B GMV) specializes in electronics resale with a 14.8% take rate.

TikTok Shop leads the space with a $17.5B GMV goal for 2024 and aggressive 6% commission rates in the US. CommentSold ($4.4B lifetime GMV) focuses on enabling small businesses and boutiques to run livestream sales. Both platforms leverage existing social media audiences rather than building dedicated communities around specific categories.

StockX and GOAT dominate sneaker resale with authentication services and standardized pricing. Both platforms have expanded into luxury accessories and collectibles. Pokemon card marketplace TCGPlayer offers detailed card condition guidelines and authentication services. These specialists typically maintain higher take rates (12-15%) justified by category expertise and trust services.

The competitive dynamics are shifting as TikTok Shop's aggressive pricing and massive user base challenges specialist platforms. Meanwhile, traditional marketplaces are reducing fees to compete with no-commission models. Authentication services have become a key differentiator in high-value categories, with most platforms either building in-house capabilities or partnering with third-party authenticators.

Whatnot has tailwinds from the explosive growth of livestream commerce and collectibles markets, with opportunities to expand into new verticals and geographies while building a broader commerce infrastructure.

The global livestream shopping market is projected to reach $600B by 2027. Whatnot holds nearly 60% market share across North America and Europe within an estimated $22B live-shopping market spanning those regions, and its platform drives 10x more transactions than traditional marketplaces—positioning it to capture share from both ecommerce giants and specialty retailers. The expansion into Beauty, Electronics, Jewelry, and Wholesale demonstrates the platform's ability to replicate its collectibles flywheel in adjacent categories, with 35+ new categories launched in 2025 alone.

Whatnot's international momentum is accelerating across both established and emerging markets. European sellers grew 600% YoY, with buyers watching 340,000 hours of livestreams weekly and sellers hosting 20,000+ hours of shows per week across the region. Cross-border sales among the U.K., France, and Germany grew 40% month over month, with some markets seeing up to 60% of sales transact internationally. The Australia launch added hundreds of shows crossing $10K in sales. The Middle East presents a further opportunity, with regional sneaker sales showing 35% higher AOV than global averages, and East Asian markets offer access to the region's established livestream commerce behavior.

With $8B in annual GMV and more than 20M new accounts created in a single year, Whatnot can evolve beyond a marketplace into a broader commerce infrastructure player. The "Bagged & Verified" authentication program signals a move into trust services for high-value categories, and the company could further develop financial products for sellers and inventory management tools to increase platform stickiness and boost take rates beyond the current 12.5%.

Recent partnerships with luxury brands, wholesale suppliers, and IP holders indicate potential to bridge the gap between traditional retail and livestream commerce. By becoming a key distribution channel for both new and secondhand goods, Whatnot could capture a significant portion of the $200B+ social commerce market while maintaining its high-engagement, entertainment-first approach.

Category expansion dilution: Whatnot's rapid push into 35+ new categories—including Beauty, Electronics, Jewelry, and Luxury—risks diluting its core collectibles differentiation while straining trust-and-safety resources that must now cover counterfeiting and return fraud at scale. Whatnot's 2025 DSA transparency report logged 64,452 reports of potentially violative content, 13,772 enforcement actions from user reports, and 111,457 proactive account bans, underscoring the operational load of policing a fast-expanding platform.

Profitability path: Despite reaching $8B in GMV and roughly $1B in revenue in 2025, the company remained unprofitable as of mid-2025, raising questions about whether the platform's entertainment-driven model can absorb the cost structure of simultaneous category, geographic, and product-format expansion. Ongoing investment in marketing, international operations, Trust & Safety, and seller tooling—all cited as priorities for Series F capital—continues to pressure margins.

Seller economics pressure: With thousands of new sellers joining monthly, category saturation is becoming a serious issue, and the introduction of advertising products to boost visibility increases the effective take rate on sellers already being courted by TikTok Shop's 6% commission rates. A seller protection policy placing refund liability on sellers for late shipments without confirmed drop-off adds further cost pressure that could accelerate churn among mid-tier sellers.
