Stoa Markets (YC S26): The Infrastructure for AI Hardware Trading

Stoa serves as the foundational market layer for AI hardware, enabling the buying and selling of GPUs through price discovery and verified counterparties.

The Problem: A Fragmented Ecosystem

Currently, the supply of high-end GPUs lacks a centralized price discovery mechanism. The market is fractured across several silos:

• OEM Allocations: Direct from manufacturers.
• Cloud Capacity: Available compute slices.
• Brokers & Operators: Middlemen and data center managers.
• Secondary Sellers: Used or refurbished hardware.

Why Pricing is Opaque

The actual "clearing price" of a GPU is a moving target influenced by several variables:

1. SKU: The specific model (e.g., H100 vs A100).
2. Logistics: Delivery timing and geographic region.
3. Volume: Total quantity requested.
4. Condition: New, refurbished, or used.
5. Financials: Available financing and the urgency of the buyer.

Because of this, buyers and sellers are often forced to rely on stale lists, private quotes, and incomplete "color" from brokers.

The Stoa Solution

Stoa provides a platform to price GPU supply, identify actual clearing levels, and execute trades with trust.

Market Pricing Examples

Below are illustrative clearing levels for various hardware configurations:

Sample Quote Calculation

For a high-end node configuration (e.g., 8 nodes of H100 SXM5, Grade A), the total cost is calculated as:

$\text{Total Cost} = \sum (\text{Price per Node} \times \text{Quantity})$ $\$262,900 \times 8 = \$2,103,200$
