What Is Stoa?

GPU supply is fragmented. OEM allocations, cloud capacity, brokers, operators, and secondary sellers each expose a different slice of the market — with no shared price discovery layer. Stoa (from Y Combinator S26) is an institutional marketplace that aggregates that supply into a single venue, pairing it with verified counterparties and real-time price signals.

The founding team (Berat Celik, Eren Berke Saglam, Kaan Yigit) positions Stoa as the solution to the “counterparty risk vs. market reach” tradeoff that plagues GPU procurement today. Every trade on Stoa involves verified parties, firm quotes, and transparent clearing levels.

How It Works

Stoa describes three core problems it solves:

Supply is scattered. OEM allocation, cloud capacity, brokers, operators, and secondary sellers each expose a different slice of the market. Stoa aggregates them into one venue.

Price depends on context. SKU, delivery timing, region, quantity, condition, financing, and urgency all affect where GPUs actually clear. Stoa surfaces those clearing levels so buyers and sellers have a shared reference point.

Signals are incomplete. Buyers and sellers historically rely on private quotes, stale lists, and broker color. Stoa replaces that with firm quotes backed by verified counterparties.

Current GPU Pricing on Stoa

Stoa displays live market-clearing prices for enterprise GPU hardware. Indicative ranges visible at launch:

| GPU | Approximate Market Price | |-----|------------------------| | A100 80GB | $9,490 | | H100 SXM5 | $25,860 | | H200 SXM | $33,850 | | B200 | $43,860 | | GB200 NVL72 | $67,400 |

Prices are indicative and vary by configuration, quantity, and delivery terms.

Practical Evaluation Checklist

• Marketplace for institutional GPU procurement — not a consumer or developer tool
• Real-time price discovery for enterprise GPU SKUs
• Verified counterparties reduce counterparty risk on each trade
• Clearing level transparency across the whole market
• Direct inquiry / contact team for pricing and execution

Security Notes

• Verified counterparties on every trade — reduces fraud risk in secondary GPU market
• Payment and execution handled through the platform
• Founded 2026, relatively new entrant — evaluate operational track record before large transactions

FAQ

Q: Is Stoa open source? A: No. Stoa is a proprietary marketplace platform. The source is not publicly available.

Q: What GPUs does Stoa support? A: Current listings include A100, H100, H200, B200, and GB200 NVL72 configurations. Supply varies by region and quantity.

Q: Is this only for large institutions? A: The platform is described as institutional, but individual buyers and sellers can join. Terms and minimums should be confirmed directly with the Stoa team.

Q: How does Stoa compare to buying direct from cloud providers? A: Cloud providers like AWS, GCP, and Azure offer GPU instances on-demand. Stoa targets buyers who want to purchase physical hardware outright, including secondary market and bulk procurement.

Q: Where can I see actual prices? A: Prices shown on the site are indicative clearing levels. Contact the Stoa team for firm quotes on specific configurations.

Conclusion

Stoa fills a real gap in the AI hardware ecosystem: a centralized, institution-grade marketplace for GPU procurement with price discovery and counterparty verification built in. For teams or organizations buying physical GPU hardware at scale, it removes the fragmentation and opacity that has historically made secondary GPU markets difficult to navigate. The YC S26 backing signals investor confidence in the AI infrastructure layer.

If you are evaluating GPU procurement options — whether for on-prem clusters, secondary market deals, or broker aggregation — Stoa is worth a look.
