Yes, I'm sure they can afford to buy tens of billions in servers just to store until obsolescence while they're trying hard to even become profitable lol
OpenAI bought up memory wafers, not ready-made systems from nvidia. That's something they may actually be hoarding to create a bottleneck.
And when they put all of that into their new RAM business, their investors are going to have a bunch of questions.
Even with tens of billions in cash it's not that simple. Like I said, you first start off by convincing a bunch of people their non-competes and give up their massive annual bonuses, so that's going to be an investment that the existing companies don't have to make. Then you'll have caught up with RAM manufacturing in about 10 years or so once you've ironed out all the details.
China, the biggest economic powerhouse in the world and the epicenter of modern electronics manufacturing, is still not making HBM3 or 4 or whatever nvidia uses now for Rubin at a commercially viable scale at CXMT, they're only barely making enough DDR5 to get contracts.
That's after starting the company in 2016 and getting DDR4 manufacturing going in 2020 and getting people from Samsung to steal trade secrets (and come work for them).
Just because you can build a fab for 20 billion doesn't mean it's only 20 billion to get started, or a quick 2-3 year endeavor to do so. Publicly traded companies can't really do this because it's a bunch of expenses over multiple years without a single cent of revenue for many years. This needs to be properly private cash or government backing.
