Every reseller faces the same question: which platform should I focus on? The answer, backed by data from high-volume resellers, is all of them — but with different strategies per platform.
Here's the complete breakdown for 2026.
Platform Overview
| Platform | Monthly Buyers | Seller Fee | Best For |
|---|---|---|---|
| eBay | 135M+ | ~13.25% final value | Electronics, collectibles, anything |
| Poshmark | 80M+ | $2.95 or 20% | Women's fashion, luxury brands |
| Mercari | 50M+ | 10% + payment processing | General items, home goods, toys |
| Depop | 35M+ | 10% | Vintage, streetwear, Gen Z fashion |
eBay — The Volume King
With 135M+ active buyers, eBay has more eyeballs than the other three platforms combined. The search algorithm rewards detailed listings with complete item specifics. Fees are higher than they look — factor in the payment processing fee on top of the 13.25% final value fee.
Best categories: Electronics, vintage collectibles, sports cards, branded sneakers, tools, auto parts.
Worst for: Fast fashion, low-ticket items under $15 (fees eat the margin), anything where authenticity verification matters (buyers prefer Poshmark's authentication for luxury).
eBay strategy in 2026: Use Promoted Listings for items above $30. Free shipping + detailed specifics beats everything else for search ranking. Auction format is dead for most categories — use Buy It Now.
Poshmark — The Fashion Community
Poshmark runs on social mechanics — sharing, following, Posh Parties. The algorithm rewards active sellers who share their own listings multiple times per day. If you're not sharing, you're invisible.
Best categories: Women's clothing (especially designer/brand-name), handbags, shoes, athleisure, kids' clothing.
Worst for: Electronics, home goods, items under $15 (the $2.95 flat fee kills margin on cheap items), anything that doesn't photograph well.
Poshmark strategy in 2026: Share your listings 3-5x per day. Participate in Posh Parties in your category. Offer discounts to likers — Poshmark notifies them when you drop the price, which drives quick sales.
Mercari — The General Marketplace
Mercari is the easiest platform to sell on. No social mechanics, no sharing required — list it and forget it. Lower buyer expectations mean you can sell items in any condition. The app experience is cleaner than eBay.
Best categories: Home goods, baby/kids items, games, books, craft supplies, anything mid-range ($15-$75).
Worst for: Luxury items (buyers don't trust authenticity), high-value electronics (eBay buyers are more comfortable with big purchases).
Mercari strategy in 2026: Price slightly lower than eBay — Mercari buyers expect a deal. Use Mercari's "Smart Pricing" feature to auto-drop price until it sells. Ship fast — shipping speed affects your seller rating which affects visibility.
Depop — The Gen Z Resale App
Depop's buyer base skews 18-26, heavily into vintage, streetwear, Y2K fashion, and anything "aesthetic." The algorithm is Instagram-like — quality photos and hashtags drive discovery more than titles.
Best categories: Vintage clothing (especially 90s/00s), streetwear brands (Supreme, Palace, Stussy), band tees, denim, anything visually unique.
Worst for: Generic basics, home goods, electronics, anything that isn't visually interesting.
Depop strategy in 2026: Photography is everything. Natural light, aesthetic backgrounds, modeled shots outperform flat lays. Use 5-8 relevant hashtags. Price competitively — Depop buyers comparison shop more than any other platform.
The Real Answer: Sell on All Four
Top-earning resellers don't choose one platform — they crosslist everything. The same item can sit unsold on Poshmark for months while selling the same day on Mercari. Different buyers, different algorithms, different luck.
The math is simple: listing on 4 platforms instead of 1 increases your chances of a sale by 4x, with roughly the same effort if you use a crosslisting tool.
The only downside is managing double-sells — you need to delist from other platforms the moment something sells. This is the main reason crosslisting tools exist.
