Fractional investment. nVidia invests $1bn for 10% of your company, you use that valuation to get another $3bn in loans and then use the money to put on a party and show your product off to lure in someone who is willing to invest $2bn for 5% of you company.

You haven’t got a working product, but your company has raised $6bn in capital/debt and you have a valuation over $40bn. You spend the $6bn on hardware from nVidia and others, propping up their share price. They invest it back in your business too. Boosting your valuation some more.

No real money has traded hands, and you’ve just been given hardware in exchange for a portion of your business.

If your business fails, nVidia and your other investors are left holding the bag…
