Yesterday Tesla announced that they are purchasing $1.5B worth of bitcoin. It is unknown at what price they are purchasing at this moment, however excluding Tesla we are seeing 0.56% of the total market cap of BTC held by public companies. It is expected that the number may continue to grow as more public companies consider whether to hold bitcoins or not as part of corporate treasuries.

The other risks is how would governments and regulators respond to this as more private companies are looking to acquire bitcoin over fiat currencies
