Sorry, but $10 billion is 1/300th the value of Nvidia alone, much less of the entire stock market.
This will have no effect whatsoever on the value of the rest of the stock market.
All that is left in stocks is mostly large companies. It is obvious the stock market is chasing fewer companies between bankruptcies and private investment. New companys are looking strongly at private investment for a variety of reasons.
Not the least of which is government regulation. Paperwork as a public company is non-trivial.
