Stoa's commodity-market bet: an RFQ floor for GPUs and AI servers, out of YC S26
Stoa bets GPU hardware trades like commodities — verified dealers, firm quotes, escrow — and its YC S26 marketplace sees $300M+ RFQs in month one.
Stoa
What the business is
Stoa runs an institutional marketplace for buying and selling new and used GPUs and AI servers: buyers describe a trade, verified dealers reply with firm quotes, and settlement runs through escrow with evidence required at every step.
How it started
Stoa was founded by ex-xAI engineer Berat Celik with Eren Berke Saglam and Kaan Yigit, and joined Y Combinator's Summer 2026 batch. The founding observation was that GPU supply is fragmented across OEM allocations, brokers, cloud operators and secondary sellers, and that price depends on SKU, delivery timing, region, quantity, condition and urgency — so deals still run on private quotes, stale lists and broker phone calls.
What happened
Stoa launched on Hacker News on August 10, 2026 as a structured alternative: a buyer describes hardware in plain language or uploads a quote PDF, an AI drafts the RFQ, verified dealers submit firm quotes, accepting a quote creates a binding trade, and payment is held until delivery confirms, with evidence required at each settlement step. The founders report more than $300M in RFQs in the platform's first month. Indicative prices shown on the site include A100 80GB at $9,490, H100 SXM5 at $25,860, H200 at $33,850 and B200 at $43,860, with an eight-node H100 cluster quoted at $1.95M against a $2.10M off-market estimate.
How it ended up
Live and early: as of early September 2026 Stoa is onboarding institutional buyers and sellers of GPUs and AI servers, with trades concentrated in North America and Europe, and says the next steps are term deals, AMD inventory and a public GPU price benchmark.
Background
Stoa was founded by ex-xAI engineer Berat Celik with Eren Berke Saglam and Kaan Yigit and backed by Y Combinator's Summer 2026 batch. Its founding observation: GPU supply is fragmented across OEM allocations, brokers, cloud operators and secondary sellers, and price depends on SKU, timing, region, condition and urgency — so AI hardware deals still run on private quotes and broker phone calls.
The product is an institutional RFQ marketplace. Buyers describe a trade in plain language or upload a quote, an AI drafts the request, verified dealers submit firm quotes, and accepting creates a binding trade; payment is held in escrow until delivery confirms, with evidence required at every step from confirmed to settled. The company says that structure replaces wire-and-hope risk with auditable records lenders and funds can underwrite against.
Stoa launched publicly on Hacker News on August 10, 2026, where the thread drew 77 points and 51 comments. The founders report more than $300M in RFQs through the platform in its first month. Indicative prices on the site run from an A100 80GB at $9,490 to a GB200 NVL system at $67,400, with an eight-node H100 cluster quoted at $1.95M versus a $2.10M off-market estimate.
The bet is that AI hardware is becoming a traded asset class, and that the venue which supplies price discovery and counterparty trust will capture the flow. Stoa's roadmap includes term deals, AMD inventory and a public GPU price benchmark — while rival marketplaces launched on Hacker News the same month signal the category is already contested.
What has to be true
- The premise is concrete: GPU supply is fragmented across OEMs, brokers, clouds and secondary sellers, and price depends on SKU, timing, region and condition — with no shared price-discovery layer.
- The mechanics replace a real trust gap: verified counterparties, firm quotes and escrowed settlement with evidence at each step turn wire-and-hope GPU deals into recorded trades.
- The launch is dated: the Launch HN thread ran August 10, 2026 at 77 points and 51 comments, and the founders report $300M+ in RFQs within the first month.
- The wedge is owning rather than renting: unlike Vast.ai and RunPod's hourly compute, Stoa targets purchase of new and used hardware — the side of the market with no public venue for price discovery.
What can be applied
Bring market structure before the market exists: firm quotes, verified counterparties and escrow let GPU trading sell trust and price discovery — what phone-and-spreadsheet deals cannot scale.
Aftermath
As of September 2026 Stoa is live and onboarding institutional buyers and sellers of GPUs and AI servers, backed by Y Combinator's S26 batch, with trades concentrated in North America and Europe and RFQ volume the founders put above $300M in the first month. The open questions are liquidity and trust: whether the venue attracts enough verified supply and demand to become the reference price for AI hardware, and whether counterparty fraud and copycat marketplaces erode its edge before scale arrives.
