This is tiny. $26b overall is being added to Anthropic at IPO in a special deal to make IPO smaller. $500m to OpenAI is a drop in the bucket for what they need within next 3 months. It is $1b total, and a tiny fraction of TSMC cash. Also IPO can be a big bag transfer event, as the $26b is all unrestricted. Though bubble fucking a few months longer seems to always be the plan.
