"until I can get a few shares at a reasonable valuation"

I doubt you will. Most likely IPO reference price will be like SpaceX's, 100x ARR or so.

You're better off buying Google who own a huge chunk of Anthropic at a much saner average.

If it's 100x ARR then I'll watch from the sidelines.

But if it's 40x in October, and inference margin is strong, and revenue is still growing 20% per month, then I'm in.
