Probably so, but that doesn't mean their value can keep scaling without heavy diminishing returns. Softbank must assume they've taken 80%+ of the gains from this phase of NVIDIA's growth, and want to capture the next wave of growth.

I agree with you that OpenAI seems much more risky in terms of it's actual true viability as a business, but the risk:reward must be there for Softbank.
