Nvidia Details $500M Corning Fiber Bet, Part of $40B AI Supply Chain Spree

Nvidia detailed a $500 million initial investment in Corning—potentially rising to $3.2 billion via warrants—to fund U.S. fiber optic plants expanding production 50% and optical capacity tenfold for AI data centers, sending Corning shares up 12%. This caps an investing frenzy that began May 6 with Legora's $600 million Series D at $5.6 billion valuation, continued May 7 with Corning prepayments, May 8 with $2 billion Nebius stake, $2.1 billion IREN option and $3.4 billion cloud deal for 5GW infrastructure, and May 9 disclosure of $40 billion total including $30 billion OpenAI. The moves secure Nvidia's AI ecosystem amid 70% yearly stock gains.
