Export controls, entity listings, tariffs and countermeasures shape who can buy which accelerator, and increasingly who can rent one. This is the running record of those rules as they're reported.
No rules recorded yet. Each entry names what it restricts, which jurisdiction issued it, and the filing behind it; the reported coverage below is what the weekly pass reads from.
Export controls restrict which accelerators can be sold into which countries, usually by drawing a performance threshold that a given part falls above or below. Vendors respond by designing parts that sit just under the line, and the line then moves.
The cloud question is the live one: a rule on selling a chip into a country doesn't automatically cover renting time on that chip from a datacenter elsewhere. Recent reporting centres on closing exactly that gap.
Rules bind at points in the chain — a foundry in one jurisdiction, equipment from another, a customer in a third — which is why the same announcement can matter to a fab and not at all to a board partner.
