# Introduction

> A GPU marketplace — rent GPUs by the hour, or list your own and earn.

GPU Outlet is a **GPU marketplace**. Sellers list GPU machines they own; buyers
rent that capacity by the hour. You can be either side — rent a GPU in a couple
of minutes, or list a spare box of your own and earn while it would otherwise
sit idle.

## Renting on the marketplace

<AccordionGroup>
  <Accordion title="Per-second billing, prepaid wallet" icon="wallet">
    Rentals are metered every second and drawn from a prepaid wallet you top up
    once via Stripe. No invoices to chase, no contracts, no procurement calls.
  </Accordion>

  <Accordion title="A broad GPU catalog, live availability" icon="layer-group">
    The marketplace spans data-center accelerators (H200, H100, A100, L40S,
    MI300X…) through workstation cards (RTX 6000 Ada, RTX 5090, RTX 4090…).
    Because it's a marketplace, what's in stock and at what price shifts with
    what sellers list — the live picture is always on the
    [marketplace](https://gpuoutlet.ai/app/create).
  </Accordion>

  <Accordion title="Trust signals on every listing" icon="handshake">
    Each seller listing shows a **Seller Rating** (0–100) and a **Verified**
    badge once the hardware has passed automated checks — so you know what
    you're getting before you launch.
  </Accordion>

  <Accordion title="Rent a whole machine — GPUs pooled together" icon="server">
    When you rent more than one GPU on a machine, you get the **whole box**: the
    GPUs are pooled in a single node with their fast interconnect, ready for
    multi-GPU training — not scattered across separate hosts.
  </Accordion>

  <Accordion title="On-demand or Spot" icon="gauge">
    Pick **On-demand** for uninterrupted capacity at the headline price, or the
    cheaper **Spot** tier, which may be reclaimed when a full-price on-demand
    buyer needs the GPU. See
    [Instances → Service tiers](/concepts/instances#service-tiers).
  </Accordion>

  <Accordion title="Instant SSH" icon="key">
    Add your public key once in **Settings → SSH keys**. It's injected into
    every machine you rent — your private key never leaves your computer.
  </Accordion>
</AccordionGroup>

## Selling on the marketplace

Have a GPU box sitting idle? List it and earn by the hour. Selling is
**self-serve** — connect your machine, it's verified automatically, and it goes
live for buyers. No approval queue, no sales call.

<CardGroup cols={2}>
  <Card title="How selling works" icon="hand-holding-dollar" href="/guides/selling">
    Connect a machine, set a price, publish, and earn as it's rented.
  </Card>

  <Card title="Open the Sell dashboard" icon="gauge" href="https://gpuoutlet.ai/app/supplier">
    Add a machine and manage your listings, earnings, and Seller Rating.
  </Card>
</CardGroup>

## How it fits together

```mermaid theme={null}
flowchart LR
  S[Seller] -->|"Lists a machine"| M[Marketplace]
  B[Buyer] -->|"Tops up via Stripe"| W[Prepaid wallet]
  B -->|"Picks a listing + template"| M
  M -->|"Boots the machine with your SSH key"| I[(Running instance)]
  I -->|"Per-second meter"| W
  W -->|"Earnings, minus platform fee"| S
  I -->|"ssh root@host"| B
```

The marketplace matches buyers to sellers' machines, the billing engine debits
the buyer's prepaid wallet at the metered rate, and the seller earns for every
second their machine runs — minus a flat platform fee.

## Who this is for

GPU Outlet is built for developers and small teams that would rather ship than
fight enterprise procurement:

* **ML researchers** running training jobs that don't justify a long-term lease
* **Inference operators** spinning up nodes elastically as load fluctuates
* **Hobbyists & students** who want serious hardware for a weekend
* **GPU owners** who want to earn from idle machines
