They apparently got a lot of Azure credits and Microsoft isn't making any revenue from running OpenAI's workloads.
I would wager against comment 0 that said that this will materially affect earnings.
People here wanted Google scale of operations and replacing Google with ChatGPT as their search engine.
But it seems that some here have forgotten about the high availability requirements and incalculable operational costs of running a search engine. Google.com's availability is a very high barrier of serving in the multi-billions of searches a day.
Azure has lots of experience in unreliability and running services at a massive loss whilst minting credits to compete on cost.
What is the true marginal cost to MSFT for gpt workloads anyway? As long as it's not bumping paying customers then it's what the cost of electricity?
