Billionaire investor Leo KoGuan has purchased 1 million shares of Nvidia, valued at $183 million, dismissing fears of an AI bubble. KoGuan, known for his investments in Tesla, believes Nvidia will rebound despite its current sideways trading at $183, 14% below its all-time high. Nvidia continues to benefit from industry growth, with companies like IREN and Mara Holdings increasing their orders for Nvidia chips. IREN plans to buy 50,000 Blackwell chips, potentially worth $1.5 billion. Nvidia's stock is trading at 22 times forward earnings, suggesting it is undervalued compared to peers like Microsoft and Tesla.
