OpenAI co-founder Ilya Sutskever is raising over $1 billion for his AI startup Safe Superintelligence, which would value the company at over $30 billion, making it one of the most valuable private tech companies in the world. San Francisco-based venture capital firm Greenoaks Capital Partners is leading this funding round, planning to invest $500 million. Greenoaks has previously invested in AI companies ScaleAI and Databricks. This funding will significantly boost Sutskever's valuation, showing a substantial increase from the previous $5 billion. However, negotiations are still ongoing, and details may change.
