How to diligence a Blackwell supplier: five questions that end the conversation

You will be offered Blackwell at a good price by someone you have never heard of. It happens constantly. The question is not whether the offer is real — it is whether the units behind it are, and whether you want to own the regulatory exposure that comes attached.

Why this is different from buying servers

Advanced GPU platforms are export-controlled. That means a transaction is not simply a commercial matter between a willing buyer and a willing seller — it sits inside a regulatory framework that follows the goods, and, in some circumstances, follows them across subsequent resales.

A buyer who accepts undocumented stock inherits three problems at once: the regulatory exposure, a warranty and support position that may not exist, and an asset that becomes very hard to resell because the next buyer will ask the questions you did not.

The five questions

1. Where does the allocation originate, and can you show me? Not "we have a relationship". Documentation. The chain from the manufacturer or authorised channel to the entity offering you the units.
2. Who is the contracting entity, and where is it registered? Then go and check it. A trade licence, a registration number, a real registered address. This takes twenty minutes and eliminates most of the field.
3. What is the end-user certificate path? If the supplier looks confused by the question, the conversation is over. If they say it is not necessary, the conversation is very much over.
4. What is the routing? Where do the goods physically travel from, through, and to. Certain routings raise questions that you will have to answer later, to someone with more authority than a procurement committee.
5. Who has actually taken delivery from you before, and can I speak to them? Not a logo on a slide. A reference who took physical delivery of a comparable volume.

The tell

The pattern is consistent. A supplier with a real allocation answers these questions in a single email, because the documents already exist and sending them is trivial. A supplier without one produces urgency instead: the allocation is moving, another buyer is circling, the price is only good until Friday.

Urgency is not evidence. It is the substitute people reach for when they do not have any.

What it costs to be disciplined

Deals. It costs you deals, and it costs you margin, and there will be a moment where a competitor closes something you walked away from and it will feel like you were wrong.

You were not. Undocumented silicon is a liability wearing an asset's clothes, and the bill arrives later, to someone senior, in a setting nobody enjoys.
