Brokers are reselling prepaid AI model credits at deep discounts: a sign the current AI build out is over buying compute.
A broker recently emailed a reporter at Vectoral offering to route $100,000 a day in AI model spend through a proxy key pool. The offer is a small data point on a secondary trade in unused inference credits, the prepaid access to AI models from providers like Anthropic and OpenAI that venture-funded startups buy in bulk and often cannot burn through.
A startup signs a multi-thousand- or multi-million-dollar deal with a model provider, draws down a fraction of the prepaid spend, and lists the remainder on a marketplace. A buyer, typically a smaller team, a researcher, or a developer in a region where direct provider access is slow or expensive, picks up the credit at a discount and routes requests through a proxy the seller controls. The seller never hands over the provider key; the proxy is the trust layer.
Vectoral, whose founder obtained the broker's contact through his own network, identified a short list of named marketplaces now operating in this lane: AI Credits runs a full onboarding flow with preferred-delivery selection; AICreditMart operates as a pure-play reseller; bulk-discount sites CheapCredits, Tokvana, and Neokens position their discounts as derived from bulk purchasing power. Vectoral itself listed credits on AI Credits and reports the listing is still pending approval, a sign that onboarding friction is part of the business model rather than an accident.
Discounts of around 40% are common marketing copy on these sites. Vectoral's own assessment is that a 40% discount is "very unlikely" for a legitimate reseller outside of bulk terms, because a reseller who buys credits at face value and sells them at 60 cents on the dollar is paying the provider's full margin and leaving no room for a sustainable spread. The HN discussion on the Vectoral post pushes the same point further, with commenters noting that discounts of 90% or higher tend to come from a different supply pool: stolen API keys, stolen credit cards, automated trial-account signup, or silent API substitution where one provider's outputs are passed off as another's.
Legitimate brokers operate as proxy forwarders running a pool of keys and absorbing the compliance risk. OpenAI and Anthropic terms of service prohibit credit transfer, so a founder whose relay traffic is traced by IP faces account flagging or termination. One HN commenter flagged a YC Startup School participant who tried to resell a $2,500 credit grant; the listing did not last.
Venture-funded AI startups routinely sign prepaid model-spend commitments sized to aggressive usage forecasts, then miss those forecasts as inference costs fall and in-house models substitute for paid API calls. The resale market is the clearing mechanism for that overhang. The $100,000-a-day proxy offer in the Vectoral inbox is one broker's estimate of how much spend is sitting unused in a small set of startup accounts, and how much of it the holders would rather monetize at a loss than write off.
None of the named marketplaces have published audited volume figures, and the snapshot of brand names could be stale by the time any of them is revisited. In the current AI build-out, buyers of compute are systematically over-provisioning, and the resale market is the receipt for that overhang.
