Elon Musk's wealth has reached a new peak, hitting $347.8 billion, largely due to a surge in Tesla stock and a fresh funding round for his AI startup, xAI. This marks a 52% increase in his net worth this year, according to Bloomberg. Tesla shares rose 3.8% on Nov. 22, nearing their all-time high from 2021. Musk's fortune is mainly tied to his stakes in Tesla and SpaceX, with the latter potentially adding another $18 billion soon. Meanwhile, Musk humorously entertained the idea of buying MSNBC after Comcast announced plans to spin off its cable companies.
