eBay vs. Poshmark vs. Mercari vs. Depop: The 2026 Platform Comparison

Choosing the right selling platform is one of the most consequential decisions a reseller makes — and in 2026, the landscape has shifted enough that last year's advice may be wrong. Poshmark reverted to 20% fees. Depop dropped to 0% seller commission. eBay is acquiring Depop. Whatnot exploded. And the tariff-driven secondhand boom is bringing new buyers to every platform.

This guide compares the four biggest resale platforms side by side with real 2026 fee data, audience profiles, and honest recommendations for who should use what.

The Master Comparison Table

eBay: The Biggest Pond

eBay is the default platform for resellers who sell hard goods, electronics, collectibles, and high-value items. With 130+ million active buyers and global reach, it offers the largest potential audience for almost anything you can sell.

Strengths: Largest buyer pool. Best for non-fashion categories. Powerful search-driven discovery. Auction format for rare items. Global shipping program for international sales.

Weaknesses: Higher learning curve (shipping, returns, promoted listings). 13.25% FVF adds up. Buyer-friendly return policy can lead to frustrating disputes.

Best for: Collectibles, electronics, vintage hard goods, sports cards, home goods, and anything you'd search for by name or model number. Read the full eBay seller guide for setup details.

Poshmark: The Social Closet

Poshmark is the go-to platform for women's fashion, shoes, and accessories. Its social features (sharing, Posh Parties, Offers to Likers) create a community-driven selling experience that's different from eBay's transactional approach.

Strengths: Simplified flat-rate shipping ($6.49). Social features drive engagement. Strong for mid-tier fashion brands (Lululemon, Madewell, Anthropologie). Posh Authenticate for luxury items. Low learning curve.

Weaknesses: Highest seller fee (20%). Limited to fashion-adjacent categories. Algorithm changes mean old strategies don't work. Buyer demographic is narrow.

Best for: Women's clothing, shoes, activewear, handbags, and accessories. Read the full Poshmark seller guide for the 2026 algorithm playbook.

Mercari: The Easy Middle Ground

Mercari positions itself between eBay's complexity and Poshmark's narrow focus. It accepts almost everything, has reasonable fees, and offers the lowest barrier to entry of any platform.

Strengths: 10% seller fee (lower than eBay and Poshmark). Accepts almost any category. Simple listing process. Promo shipping deals — currently $4.99 for UPS/FedEx 1–5 lb through April 16, 2026.

Weaknesses: Buyer protection fee (3.25%) and $2.00 payout fee are passed to the buyer, which can reduce demand. Price-sensitive buyer base. Less brand recognition than eBay.

Best for: General merchandise, toys, home goods, mid-range clothing, and "digital yard sale" items that don't fit neatly into eBay or Poshmark's sweet spots.

Depop: The Gen Z Marketplace

Depop is where Gen Z shops for vintage, streetwear, and trend-forward fashion. The 0% seller commission in the US (since July 2024) makes it the cheapest platform to sell on — though that may change after the eBay acquisition.

Strengths: 0% seller commission (US). Gen Z audience that's hard to reach elsewhere. Social/discover feed drives impulse purchases. Crosslisting now explicitly allowed in 2026 ToS.

Weaknesses: Smaller audience than eBay or Poshmark. Fee structure may change post-eBay acquisition. Younger buyer base can be more price-sensitive. Not ideal for non-fashion items.

Best for: Trendy vintage clothing, streetwear, Y2K fashion, unique/curated fashion items. Read our Depop beginner's guide for the full setup. And read our eBay + Depop acquisition analysis for what to expect.

The Wildcard: Whatnot

Whatnot isn't in the comparison table because it's a fundamentally different model — live selling rather than static listings. But with $8B+ in gross merchandise value in 2025, an $11.5 billion valuation, and 541% download growth year-over-year, it can't be ignored.

Whatnot charges approximately 11% in total fees and is strongest for sports cards, Pokemon, vintage clothing, and collectibles. If you're comfortable on camera and have inventory that generates excitement (BOLO items, sealed product, mystery lots), Whatnot is worth testing as an additional channel.

What You Keep on a $100 Sale

*Mercari's 3.25% buyer protection fee + $2.00 payout fee are charged to the buyer, not the seller — but they affect the effective price buyers are willing to pay.

Facebook Marketplace: The Local Wildcard

Facebook Marketplace deserves mention as a supplementary channel. For local pickup sales, there are zero fees. For shipped sales, Facebook charges 10%. It's not a primary resale platform, but it's excellent for furniture, large items, and anything that's expensive to ship. See our full Facebook Marketplace guide.

The Verdict: Which Platform Should You Start With?

The real answer is: use multiple platforms. The cost of crosslisting is low (especially with tools like Vendoo or List Perfectly), and the benefit — 2x–4x the buyer exposure — is enormous. Master one platform first, then expand.
