Competition among AI infrastructure suppliers is sharpening as chipmakers and optics firms jockey for position. Former Intel CEO Pat Gelsinger has backed a $100 million effort challenging Nvidia's AI networking dominance, a move that could benefit AMD, while Intel's potential Altera divestiture is also drawing AMD's attention as a rival. Meanwhile, a little-known AI chip stock doubled after unveiling chips that double optical speed. In the optics space, Lumentum shares jumped nearly 10% while Corning's stock barely moved, suggesting the AI optics trade may be diverging between winners and laggards as investors grow more selective about which suppliers will capture AI data-center buildout spending.
