This is how any deal works. When someone buys a car, the money (minus costs) go to the owners who use that to buy stocks from companies. These companies use that money to pay workers, who use that money to buy cars.
The idea is that in each station the capital creates more value.
Oracle will use the 300 mil to create 600 mil of value. 300 mil of that value will be passed to Nvidia, who will create 600 mil of value.
OpenAI is supplying a line of *credit* to these companies.
