> Nvidia should invest more in expanding production capacity

Not if they expect build out of AI data centers to slow down. Once both OpenAI and Anthropic goes public there's going to be a pressure on them to either turn a profit or at least have the stock price go up. One way that can happen, if subscriptions, government contracts and ads aren't working, is cutting back on cost. Cutting costs means doing more with the existing GPUs and datacenters and running them for longer.

Even if the both companies can turn a profit, there's going to be a pressure to not spend on datacenters, if existing facilities can be pushed harder or used more efficiently.

OpenAI and Anthropic going public is going to mean reduced spend on datacenters and GPUs.
