First Move · Ins7ghts Daily, Tuesday 3 November 2026
Some nights did not work, and it was not the records. I had been hired as "a DJ", which in practice meant wallpaper: a jukebox with a human attached, there to hold the room at a pleasant volume, not someone to take it anywhere. Other nights ended on the owner or a neighbour complaining about exactly that volume. Either way, nobody in the building was thinking about the person choosing what came next.
Marvell spent $115 billion on Monday, in its own shares, on Lumentum, an optical components maker. The two of them call the result a category leader in AI connectivity. Read the coverage and you get two company names, one very large number, and a bet on AI data centres.
Step one hop back and it gets more useful. A deal report on 22 October has Marvell announcing a $3.5 billion acquisition of Celestial AI. A write-up on 28 October says what that bought: photonic fabric and co-packaged optics, which is the business of carrying data as light right up to the chip package instead of as electrical signal across a board. Every write-up of Celestial AI in the past month is really a Marvell write-up with a clause in it.
That is the shape of this whole layer. The optical engines, the fabrics, the pluggables and the connectors that decide how fast one rack can talk to the rack next to it come from companies with no keynote, no consumer brand and a customer list of a few dozen names they already know. They do not chase press, because press does not sell them anything. So the public story stays about who has the chips, while the part that sets how fast those chips can talk to each other gets mentioned, when it gets mentioned, as a component.
