It is also a term use in general trading anywhere traders open and close their positions quickly to make profit off an upswing which might be in part caused by traders doing this. If done with inside knowledge it is illegal, in this case more commonly referred to as “front running” (which is what many suspect happened with numerous ahemfortuitous/serendipitous position changes around announcements of changes in the state of the US vs Iran situation).

As well as the companies ordering for the purpose of DC roll-outs and upgrades, there will definitely be some buying purely to sell at a higher price a short time later.

[and with reference to the sibling reply to this: “Then we'll have a lot of cheap RAM.”]

I don't think it will pop with a sudden bang, and even if it is it won't affect these memory sales or probably those for 2028. The first real effect will be those using the AI tools suddenly finding themselves needing to pay a lot more for them as companies offering those services deal with reduced access to “new” credit from the circling investment pool shore up their fanciful accounting that way instead. The DC builds/upgrades that are currently planned will happen but more funded by end users and less by the investment cycle. New plans might not be actioned at the same scale, but it will take a while for that to affect component prices as there is a lot of lead time involved.
