Long term, incredibly capital extensive deals -- the consensus is that "yes, of course this will be funded. We see how the AI future is going to go and we want to get our money in it now". The contrarian view is, this is a Bubble and the risk is we are overbuilding (e.g. do we need this many gigawatts? do we need this many chips? etc." But I think most people agree AI will be transformative in the same way that PC's and Mobile phones were.
Interestingly I was listening to a podcast breaking down the AMD + OpenAI announcement last week and let me try to put in bullet points the key takwaway:
When OpenAI says anything about anyone, their stock goes up
When OpenAI announces a deal that we are going to do a $100bn deal with AMD chips, AMD stock very predictably goes up
They all know this when they strike a deal and agree, we should take this very predictable stock price increase and use that to pay for the chips
Further:
AMD shareholders are paying for the chips, in the sense that;
AMD stock is up roughtly $100bn from before they announced the deal
OpenAI is getting warrants for roughly 10% of AMD (penny warrants), so like worth $37bn value transfer to OpenAI
That $37bn will help pay for that contract (and it's only fair as OpenAI created all that extra value anyways by partnering with AMD they made AMD more valuable)
OpenAI has the old Elon Musk market moving touch, if you remember those days.
