Whatnot vs. Poshmark: How do they compare?

The biggest difference between Poshmark vs. Whatnot is that Whatnot is a platform for collectibles sellers who love moving their goods via livestreaming auctions. Poshmark appeals to fashion sellers via social media-driven features and uses more buy-it-now features than Whatnot.

Whatnot: A livestreaming platform for collectibles 

Whatnot lets you host livestream auctions while also allowing you to create buy-it-now listings. Buyers flock to the marketplace to find collectibles like trading cards and sports memorabilia, but more and more buyers seek other goods, like fashion and electronics. In 2025, Whatnot added over 20 million new accounts, allowing you to sell to several countries and regions.

Poshmark: A fashion-focused platform with social features

Poshmark has a community of around 130 million users across North America. Its social media feed allows buyers and sellers to follow each other, share their listings, and host live events called Posh Parties. Read our Poshmark review article for a breakdown of the platform. 

Fees and payouts

Whatnot fees and payouts

• Whatnot charges a commission of 4–8% of the sale price, depending on the category. Sports singles, toys, hobbies, and most other categories incur an 8% commission fee. Coins only incur a 4% fee. All sellers pay a payment processing fee of 2.9% + $0.30 per transaction.
• In the US, once an order is released for payout, ACH transfers usually reach sellers’ bank accounts within about 1–3 business days. New sellers may face additional payment holds of up to 7 days. Sellers in the UK, Netherlands, Belgium, and Australia receive payouts after delivery confirmation plus a 96-hour settlement period.
• Eligible sellers can also join the Early Payout Program. Available in the US, Canada, and Japan, this program allows sellers to access earnings as soon as a shipping label is generated.
• For a limited time, Whatnot is waiving commission fees on sales of items from included categories above $1,500, allowing sellers to pay 0% commission on qualifying transactions, but the 2.9% + $0.30 processing fee still applies. 

Poshmark fees and payouts

• No matter what product category, Poshmark charges $2.95 for sales under $15 and takes a 20% commission on sales over $15. It doesn’t have listing or payment processing fees.
• Sellers receive payment after the buyer accepts the order or automatically 3 days after delivery if no action is taken.
• The platform adds earnings to your Poshmark wallet, which you can withdraw via direct deposit, check, or Poshmark credit. It usually takes 2–3 days for the money to hit your bank account if you choose direct deposit.

Winner

Whatnot wins the fees and payouts comparison by a mile. On many Whatnot sales, commission plus payment processing totals roughly 10–12% of the buyer’s payment, which is typically lower than Poshmark’s 20% fee on sales of $15 or more. Plus, Whatnot pays you out earlier than Poshmark, in more cases. 

You can also get paid out in moments if you meet Whatnot’s Early Payout Program standards, but you need to sell a certain amount and have high ratings.

Buyer audience

Whatnot buyer audience

• Whatnot’s collector audience particularly focuses on finding rare trading cards, sports memorabilia, and other collectibles. These segments generally attract a younger, predominantly male customer base. But interest in fashion, beauty, and general merchandise is expanding.
• Buyers attend livestream auctions rather than browse standard product listings. Many users follow their favorite sellers and regularly join scheduled shows, purchasing items through live auctions and competitive bidding.
• Successful sellers actively demonstrate products, explain key details, and answer questions in real time. Buyers expect sellers to be knowledgeable. This direct engagement helps build credibility and often influences purchasing decisions. But like building Rome, building a Whatnot following doesn’t happen overnight. Or in a week. 

Poshmark buyer audience

• Poshmark attracts North American buyers shopping for clothing, shoes, and accessories. Many seek popular brands such as Nike, Coach, and Louis Vuitton at discounted prices.
• Buyers discover products through search, personalized recommendation feeds, and social features like shares, likes, Posh Shows, and Closet Clear Out promotions.

Winner

This one’s a tie because both Whatnot and Poshmark have niche best buyer profiles: Whatnot attracts collectors who expect high-energy live auctions, while Poshmark attracts fashion seekers. It all depends on the type of items you sell and your preferred selling style.

Listing and discoverability

Listing on Whatnot

• With Whatnot’s photo-based AI listing tools (still in beta testing), sellers can quickly create listings that buyers can view during live auctions. Sellers can increase visibility through category pages and paid advertising placements using Whatnot’s Promote Tools.
• Whatnot’s discovery system centers on its For You feed. This scrollable feed recommends live shows based on buyer activity, followed categories, bookmarked shows, and past interactions with sellers. Sellers you know can use Raids to send viewers directly to your stream, helping everyone reach new audiences.

Listing on Poshmark

• Sellers create listings by uploading up to 16 photos, adding a title and description, and selecting details such as the item’s category, brand, size, and condition. It’s built for selling fashion.
• On iPhone and iPad, Smart List AI can generate a title, description, category, and key product details from a single photo, helping sellers create listings with less manual work.

Winner

Poshmark wins for listing and discoverability. Its Smart List AI system is battle-tested and accommodates buyers on the go through the mobile app. On Whatnot, growing a loyal following and keeping viewers engaged during live auctions has a bigger impact on sales than the listing alone.

Shipping and returns

Shipping and returns on Whatnot

• If you choose buyer-paid shipping: Eligible low-value trading cards or stickers that qualify for USPS First-Class Mail Letter typically ship for about $0.74–$1.32. Combined US domestic shipments weighing between 1 and 5 lb are charged a flat shipping rate of $9.21 ($8.77 + fees). Heavier packages use USPS commercial rates, which increase with weight and sometimes service type.
• International shipping is available through carriers such as UPS, with rates varying based on the destination, package weight, and selected service level.
• Sellers can also offer free shipping by covering the label cost themselves. However, Whatnot still charges marketplace fees on the full sale amount.
• Whatnot only requires refunds for issues covered by its Buyer Protection Policy, such as items that arrive damaged, are missing, or differ significantly from the listing description. Buyer’s remorse doesn’t qualify for a return.
• When Whatnot approves a claim, refunds are issued to the buyer’s original payment method and typically arrive within several business days, depending on the payment provider and bank.

Note: Whatnot is switching to USPS Ground Advantage from August 2026, dropping the 1–5 lb rate from $9.21 to $7.20 and ending Flat Rate packaging support. Sellers using Flat Rate boxes must switch to standard packaging to avoid a surcharge of up to $20.

Shipping and returns on Poshmark

• Poshmark charges buyers a flat $6.49 shipping fee through USPS Ground Advantage for packages weighing up to 5 lb.
• Heavier items: Packages weighing 5.1–10 lb require a $5 shipping upgrade ($11.49 total), while packages weighing 10.1–15 lb require a $10 upgrade ($16.49 total). Poshmark shipping is limited to North America. Buyers pay $6.49, and sellers pay the upgrade fee ($5 or $10). 
• Sellers can choose to offer free shipping, but they must cover the shipping cost themselves, which reduces their profit on the sale.
• Poshmark only accepts returns when an item is damaged, significantly different from the listing, missing, or suspected to be counterfeit. Buyers can’t return items for fit issues or buyer’s remorse, and disputes are evaluated against the listing’s photos and description.

Winner

Poshmark wins for shipping and returns, but it’s close. Poshmark’s shipping system is easier to understand and more predictable for both buyers and sellers. The flat-rate shipping model covers most items commonly sold on the platform. Whatnot’s shipping structure varies based on item type, weight, and destination, which can get slightly confusing.
