Bloomberg reported Saturday that some of Nvidia's largest customers were told server prices will rise more than 15%, driven by soaring memory-chip costs. Nvidia hasn't confirmed it, and the stock hasn't traded on it yet. The real story isn't the price increase — it's that the AI bottleneck is moving from compute to memory, and the bottleneck always owns the margin.

Applied Materials just delivered the biggest quarter-over-quarter revenue jump in its history and the stock fell 5% anyway. One line about flat gross margins did it. Cisco beat and dropped 8.4% for the same reason the night before — while Micron, which sells the memory driving those costs, jumped over 4%. The AI trade isn't breaking. The margin is just moving down the supply chain.
