Launch HN: Stoa Markets Is Building Price Discovery for the GPU Secondary Market — A100s Through B300s
The YC S26 company argues GPU supply has no shared price discovery layer, being scattered across OEM allocation, cloud capacity, brokers, and secondary sellers with contextual pricing. Its marketplace covers A100 80GB, H100 SXM5, H200 SXM, B200, and B300 plus 4–8 GPU server nodes, with firm dealer quotes, a structured RFQ flow, and settlement tracked through confirmed → payment → shipped → delivered → inspected → settled. Its own illustrative example puts an 8-node H100 transaction at $243K on-platform versus $263K off-market. 75 points, 50 comments; no trading volume disclosed, so treat the savings figure as marketing.
