OpenAI is closing a funding round >$100B. SoftBank is reportedly investing $30B, Amazon $50B, and Nvidia $20B. This is not just an investment; it is a capital expenditure moat. For SoftBank (SFTBY), this validates their AI strategy. For Amazon (AMZN) and Nvidia (NVDA), it locks in OpenAI as a customer for compute and chips, recycling the capital back into their own revenue streams. LONG. SoftBank specifically is reacting positively to the news as a direct beneficiary of the valuation markup. Regulatory scrutiny on Big Tech consolidation of AI power.
