I was wondering the same after PRW lol. Recently I had the chance to ask a friend of mine who worked in Google Infra (years ago) if they had ever tried to 'liberalize' their infrastructure planning; something like having internal business units bid on space, power, and compute instead of distributing it top-down. He said that yes, this was actually something like their original operating model, and the outcome was that YouTube basically bought up every piece of hardware in the company and then leased them out to other verticals at a profit.
There are a few small examples that come to mind (co-ops and communes mostly), but I can’t think of any that have been successful at scale. Running an internal market would be almost pure overhead, so if it worked it would really have to be efficient to be worthwhile.
In addition to your Samsung example, I know of a major tech company whose services division often buys hardware from competitors because they get a 40% discount and priority deliveries when stock runs low. If they were to buy the in-house alternative, they'd be paying list price and be at the back of the queue for deliveries.
There's also huge scope for "funny money" Hollywood accounting-style practices, where internal prices become entirely disconnected from supply, demand, or any sort of underlying value - which actually results in the organisation being even more dominated by the whims of senior leadership than they otherwise would be.
(These problems are very similar to those experienced in country-level command economies too, of course)
