    List in minutes. Pay 7% + $0.40 on the first $3,750, then 3.5% on the amount above only when your item sells. No listing fees, no subscriptions. Held payments protect the sale, and payouts go straight to your bank.

    Founding sellers pay 5% for their first 6 months, locked in with their first listing.

    The fee math, up front

    One fee: 7% + 40¢ of the order total (item + shipping). Charged only when your item sells. Payment processing is included. There is no separate processing fee.

    • No monthly subscription.
    • High-value builds and GPUs are dramatically cheaper to sell here than on general marketplaces.

    Founding sellers pay 5% + $0.40 on the first $3,750, then 3.5% above for their first 6 months. That same $500 GPU costs just $25.40 to sell.

    Local AI hardware has its own section

    List your 3090, Mac Studio or DGX Spark. Our Local AI section is built for people running AI on their own hardware.

    What it gathers
    Graphics cards with 12 GB or more of VRAM, unified-memory computers like Mac Studio, DGX Spark and Strix Halo mini PCs, multi-GPU builds and big memory kits.
    Listed with real specs
    Macs, Strix Halo mini PCs and NVIDIA Arm systems like DGX Spark can be listed with their real specs. Unified memory is a listed spec, so a 64 GB and a 128 GB DGX Spark are told apart, and multi-GPU builds carry their GPU count and total VRAM.
    What it runs, as an estimate
    Cards and computers can show which AI model sizes fit in their memory, labelled an estimate. The free Local AI calculator does the same for any card or computer, no account needed.
    Fees and protection
    Same fees, same buyer protection as every listing.

    From signup to listed in one sitting

    Three steps. Most sellers publish their first listing the same day they sign up.

    1. Step 1

      Create your account

      Free, takes about two minutes. No listing fees, no subscription. You owe nothing until something sells.

    2. Step 2

      Verify with Stripe

      Every seller here is identity-verified, and it's why buyers trust the marketplace. Stripe (the payment processor behind Amazon and Shopify) collects your legal name, date of birth, address, last 4 of SSN, and a bank account for payouts. It's a federal requirement for receiving payments, it does not register you as a business, and SiliconExchange never sees any of it. You can start your first listing before this is done. It goes live once payouts are set up.

    3. Step 3

      List your hardware

      Search your exact model (GPU, CPU, RAM, motherboard, storage, PSU) and the specs fill in automatically from our component catalog. Add photos and condition notes, set your price, publish.

    How you get paid

    Held payments protect both sides: the buyer's money is committed before you ship, so you never ship on a promise to pay. The steps below show when it's released to you; a refund after a dispute, a chargeback from the buyer's bank, or a hold on your payouts follows the rules in our Terms.

    1. Step 1

      Buyer pays, funds secured

      The buyer's payment is captured immediately and held by SiliconExchange. You ship knowing the money is already there.

    2. Step 2

      Ship within your stated handling time

      3 business days by default, or set your own on the listing: promise next-business-day dispatch and your listing carries a speed badge. Buy a discounted carrier label right on the order (no card needed, the cost simply comes out of your payout) or use your own label. On our label or your own USPS, UPS or FedEx label, carrier tracking updates the order automatically. Selling local-pickup only? Skip shipping entirely: schedule the meetup on the order, and at the exchange enter the buyer's pickup code, and your payout releases on the spot.

    3. Step 3

      Buyer releases the payment

      Once delivery is confirmed (by the carrier's scan, by the buyer or by our team), the buyer releases your payment when they're happy with the item. If they don't, it releases automatically 14 days after delivery, unless a dispute is open.

    4. Step 4

      Paid out weekly

      Released funds land in your Stripe balance and pay out to your bank every Monday.
