Amazon is the honest default answer to "which marketplace first" for 90% of DTC operators above $5M. The audience is irreplaceable (310M+ monthly US visitors, 200M+ Prime subscribers who convert at 2-3x the rate of non-Prime), FBA fulfillment solves the 2-day shipping requirement, and Sponsored Products ads give you controllable visibility if you're willing to pay for it. For most ecommerce categories, being absent from Amazon by $10M revenue is leaving $500K-$5M of growth on the table annually.

The honest trade-offs are everything the DTC community has been shouting about for a decade and all remain true. All-in fees run 25-35% once you add FBA, Sponsored Products, inventory storage, and returns — meaningfully above the headline 15% referral rate. You don't own the customer (Amazon won't give you their email). Amazon's private-label brands will eat successful third-party sellers in competitive categories (Amazon Essentials, Solimo, Amazon Basics all built on third-party seller signal). Compliance is strict (one wrong move and your listing is suspended). Brand gating exists but requires work. For most DTC brands above $5M, the right posture isn't avoidance — it's deliberate strategy: specific SKUs on Amazon, protected pricing floors, aggressive brand registry enrollment, and FBA for the SKUs where fulfillment economics work.

Walmart Marketplace is the most underrated channel for DTC operators who've maxed out Amazon economics. Audience is substantial (180M+ monthly US visitors, growing faster than Amazon in grocery and household categories), fees are more honest (15% referral with lower all-in costs than Amazon), the WFS fulfillment program is competitive with FBA on cost, and the seller base is quality-controlled — Walmart approves sellers rather than opening the floodgates. For brands that are strong on Amazon and want to diversify without taking a margin haircut: Walmart is almost always the right second channel.

The honest trade-offs: approval is required and the process takes 2-6 weeks (less democratic than Amazon's open signup but higher-quality seller base as a result). Walmart's advertising platform (Walmart Connect) is less mature than Amazon's — less sophisticated bidding, fewer targeting options, more friction. Audience skews slightly older and more price-sensitive than Amazon, which affects category fit (groceries, household, basic apparel do better; premium lifestyle does worse). Best fit: DTC brands with established categories, grocery/household/basic consumer goods, and brands wanting less-saturated competition than Amazon offers.

TikTok Shop is the single most important new channel in US ecommerce — and it's a completely different operating model from Amazon or Walmart. Discovery is driven by content (short-form video, live streams, creator affiliate campaigns), not by search. Buyers find your product because a creator showed it in a video, not because they typed your category into a search bar. The GMV growth is real ($20B+ US in 2026, from near zero in 2023), and the demographic is young enough to be building long-term purchase patterns. For brands with content-friendly products (beauty, wellness, home gadgets, apparel), TikTok Shop is a legitimate 10-30% revenue channel.

The honest reality: TikTok Shop requires a fundamentally different go-to-market strategy. You need either in-house content production or a creator affiliate program (or both). The 5-8% headline commission climbs to 15-25% all-in once you add creator affiliate commissions (typically 10-20% to the creator per sale), content production costs, and Shop Ads. Attribution is messy — your TikTok Shop sales often cannibalize or augment your DTC site sales in ways that are hard to disentangle. Fulfillment via Shop Fulfilled by TikTok is improving but less mature than FBA. Best fit: brands with visually demonstrable products, operators willing to build content capability, and products priced $15-$80 (TikTok Shop's conversion sweet spot).

eBay gets dismissed as "the old marketplace" by DTC operators who've never actually looked at the category data. The reality: eBay still dominates specific verticals — refurbished electronics (unmatched for consumer electronics resale), collectibles (trading cards, sports memorabilia, vintage), auto parts (OEM and aftermarket), industrial surplus, used musical instruments. For sellers in these categories, eBay's audience converts at rates that make Amazon look weak. For general consumer DTC: eBay is less relevant, but not dead — specific SKUs can still move at reasonable margin.

Trade-offs: eBay's platform shows its age (search UX is dated, mobile app is adequate but not polished, seller tools require manual work). Advertising via Promoted Listings is simple and effective at low cost (2-5% ad spend typically). Fulfillment is still self-managed (eBay doesn't have an FBA equivalent, though eBay Managed Delivery is piloting). Best fit: refurbished/vintage/specialty sellers, auto parts, collectibles, and any category where buyers specifically search eBay first.

Etsy is still the honest right answer for handmade, craft, vintage (20+ years old), and craft supplies sellers. The audience (95M+ active buyers) comes specifically looking for unique, non-mass-produced goods — meaning your conversion rates on Etsy will dwarf your conversion rates on Amazon for the same product. Fees are reasonable at the headline level ($0.20 listing + 6.5% transaction + 3% payment processing + offsite ads if you opt in), though the all-in reality lands closer to 18-22% once you factor Etsy Ads for visibility and the near-mandatory Offsite Ads program.

The honest tension: Etsy has been slowly losing its "handmade" soul as the platform allows more resellers, dropshippers, and manufacturer-partnered sellers to list under creative category interpretations. Legitimate handmade sellers increasingly complain about being drowned out by faster-shipping volume sellers. For a true handmade/craft brand, Etsy is still essential — but no longer a growth guarantee. Diversifying with your own Shopify site plus Etsy as a discovery channel is the modern honest strategy.

Faire is the dominant B2B wholesale marketplace, connecting consumer brands with 700K+ independent retailers (boutiques, gift shops, specialty stores) globally. For DTC brands expanding into wholesale, Faire is almost always the right first channel — the retailer discovery, net-60 payment terms, free returns on first orders, and streamlined onboarding make it dramatically easier than traditional wholesale rep relationships. For wholesale-first brands (makers, specialty manufacturers), Faire can represent 50-80% of revenue within 2 years of launch.

The honest math: Faire's 15% commission on new retailer orders (dropping to 10% on repeats after year one) sounds reasonable but combined with the free returns policy and wholesale margins already being thinner than DTC, the net economics are tight. Most sellers maintain their wholesale pricing at 50% of MSRP, which after Faire's cut means ~42-45% of MSRP in actual revenue — real wholesale economics. Faire's recent moves toward "brand-first" marketplace features (direct relationships, exclusive terms with retailers) are improving brand control but still less than independent wholesale. Best fit: makers, consumer packaged goods, gift and specialty retail categories.

Target Plus is the most selective major marketplace in US ecommerce — approval requires invitation, and Target curates sellers to maintain brand alignment with the Target shopping experience. For brands that get in (approximately 1,200 approved sellers in a market where Amazon has 2M+ sellers), the economics are legitimately favorable: lower fees than Amazon or Etsy, less competitive marketplace environment, and association with the Target brand aesthetic. Target shoppers tend to be slightly more affluent than Walmart shoppers and more trusting of marketplace sellers because of the Target gatekeeping.

The challenge: getting in. Target Plus prioritizes brands that already have strong independent brand recognition, retail distribution elsewhere, or hero products in Target-aligned categories (home, lifestyle, specialty food, beauty, kids). Cold applications rarely succeed; relationships with Target buyers or category managers help significantly. If you can get accepted: Target Plus is often the highest-margin marketplace channel available. If you can't: don't waste time pursuing it instead of channels that will actually accept you.

Shop App is Shopify's answer to "how do we help our 2M+ merchants reach new customers without them losing to Amazon?" The app aggregates products from Shopify stores into a shoppable discovery experience, powered by Shop Pay for one-tap checkout. For DTC brands on Shopify, Shop App is uniquely valuable because — unlike every other marketplace in this list — you keep the customer relationship. Your Shopify customer record is created, their email is yours, and your repeat purchase flows apply.

The honest reality: Shop App discovery is still finding its product-market fit. Organic reach for most brands is modest (users browse specific categories and brands they already know), and the pay-to-play discovery options (Shop Ads) are improving but less sophisticated than Amazon advertising. For established Shopify brands with 2000+ orders/month: Shop App is a legitimate 5-15% incremental revenue channel at near-zero friction (no new SKU setup, no new fulfillment, no new customer service workflow). For smaller Shopify brands: it's effectively free optionality — list and see what happens.

Meta Shops (Instagram Shop + Facebook Shop) is less a dedicated marketplace and more an in-feed extension of your DTC storefront. For brands already running Meta ads at scale, enabling Shops is near-friction (import products from Shopify or BigCommerce, tag products in organic posts and ads, enable shopping on the Shop tab). The 5% selling fee on in-app checkout is reasonable; the alternative is sending traffic to your DTC site for standard DTC conversion rates.

The honest limitation: Instagram shoppers overwhelmingly convert on the brand's own site, not on in-app checkout. Shops matters less as a transaction destination and more as a discovery enhancement for your DTC acquisition. For brands with strong Instagram presence and visual products (apparel, beauty, home goods, food), Shops is near-mandatory even if it drives most buyers to your site rather than through in-app checkout. For brands with modest Instagram presence, Shops delivers modest results.

Mercari is the Japan-born marketplace that's quietly built a 50M+ US user base focused on casual peer-to-peer resale. The platform is optimized for individual sellers listing pre-owned goods (apparel, electronics, home items, collectibles) in a mobile-first experience that's dramatically simpler than eBay. For brands selling refurbished inventory, excess DTC stock, or secondhand goods: Mercari is a legitimate secondary channel at 10% selling fee plus payment processing (meaningfully cheaper than eBay).

The honest limitation: Mercari is positioned as a casual marketplace, not a professional one. Volume sellers can grow here, but the platform tools (bulk listing, inventory management, analytics) are less sophisticated than Amazon, eBay, or even Etsy. For brands with professional seller infrastructure, Mercari represents incremental revenue rather than a core channel. For individual sellers and small operations in resale categories: Mercari is often the easiest marketplace to start with.
