With 70%+ profit margins on data centers, it's enough that just $1.43 billion in data center revenue is secured for $1b investment to pay back.

Nvidia's larger investments are even more conditional. With OpenAI, the investment is contingent on building huge data centers in the future. If the bubble ends, Nvidia pays nothing; if it continues, Nvidia has locked in a customer.

Nvidia plays smart with little risk.
