Forbes estimates Josh Kushner's net worth at $16.7 billion, up from $5.2 billion a year ago. His venture firm, Thrive Capital, grew its assets to over $65 billion, nearly tripling from $23 billion in December 2024. This surge is primarily attributed to his early investment in SpaceX, which reportedly became a $10 billion stake when the company went public in June, and a subsequent $4.2 billion stake in AI coding startup Cursor after SpaceX acquired it for $60 billion. Kushner also holds an indirect stake in OpenAI, last valued at $852 billion in March.
