No it hasn't, and the type of deal it is going to get looks likely to be different under Biden than under Trump. I think your point is relevant regarding ARM-Nvidia, as semiconductor technology has tended to be the subject of trade barriers, and is seen as a strategic national asset.

Yeah that’s what I was kind of getting at ... great British success story, bought by SoftBank Japan coincidentally straight after Brexit. Would have been a good asset to have in trade negotiations. The sale to US based Nvidia 3 months ago is an interesting twist that would have gone against the EU had Trump won again.
