In accounting terms, this is a shady business practice known as "round tripping" where you invest in a company for the sole purpose of them buying your product. It allows you to count your revenue multiple times.
It's a good time to gently remind everyone that there are a whole pile of legal things one can do to change how a security looks "by the numbers" and this isn't even close to the shadiest. Heck some sell-side research makes what companies themselves do look benign.
Two economists are walking in a forest when they come across a pile of shit.
The first economist says to the other “I’ll pay you $100 to eat that pile of shit.” The second economist takes the $100 and eats the pile of shit.
They continue walking until they come across a second pile of shit. The second economist turns to the first and says “I’ll pay you $100 to eat that pile of shit.” The first economist takes the $100 and eats a pile of shit.
Walking a little more, the first economist looks at the second and says, "You know, I gave you $100 to eat shit, then you gave me back the same $100 to eat shit. I can't help but feel like we both just ate shit for nothing."
"That's not true", responded the second economist. "We increased total revenue by $200!"
This kind of corporate behavior is bad and will end up hurting somebody. If we're lucky the fallout will only hurt Nvidia. More likely it will end up hurting most taxpayers.

In the end, Nvidia will have OpenAI shares, which are valuable, and OpenAI will have GPUs, which are also valuable. It is not fake revenue, the GPUs will be made, sold at market price, and used, they are not intended to be bought back and sold to another customer. And hopefully, these GPUs will be put to good use by OpenAI so that they can make a profit, which will give Nvidia some return on investment.
It doesn't look so different from a car loan, where the dealer lends you the money so that you can buy their car.
It's not necessarily manipulative but it's also not exactly an arms-length purchase of GPUs on the open market.

Also, investing in OpenAI means they get equity in return, which is not a worthless asset. There is actual mutually beneficial trade occurring.
In the actual shady version of this, Company B isn’t the hottest AI investment around, it’s a shell company created by your brother’s cousin that isn’t actually worth what you’re claiming on the balance sheet because it was only created for the round tripping shell game.
Every time HackerNews talks about anything in the legal or finance realm, people trip over themselves to make arguments for why something a big tech is doing is illegal. This is definitively neither illegal nor shady. If Nvidia believes, for example, that OpenAI can use their GPUs to turn a profit, then this is inherently positive sum economically for both sides: OpenAI gets capital in the form of GPUs, uses them to generate tokens which they sell above the cost of that capital and then the return some of the excess value to Nvidia. This is done via equity. It's a way for Nvidia to get access to some of the excess value of their product.
Microsoft and Google have been doing it for decades. Probably, MS started that practice.
... and we've seen this before in previous bubbles ...
