Elon Musk's net worth hit a new milestone, jumping to $749 billion following a significant legal victory. The Delaware Supreme Court's decision to reinstate Tesla stock options valued at $139 billion—options that had been invalidated previously—sparked the surge, according to real-time tracking on the billionaires' wealth index. The ruling, which came late Friday, represents a major reversal and underscores the intersection of corporate governance, regulatory decisions, and market movement. For those watching major player dynamics in the market, this development signals how legal outcomes can dramatically reshape individual wealth holdings and influence broader investor sentiment.
