The AI infrastructure boom is fundamentally shifting supply chain dynamics, allowing upstream component and power providers to dictate structural terms and capture record profits at the expense of consumer-facing brands.

• SanDisk (SNDK) is utilizing bank-guaranteed long-term contracts to extract massive memory margins from hyperscalers.

• Apple (AAPL) faces immediate gross margin compression as these upstream storage component costs aggressively spike.

• Caterpillar (CAT) is effectively serving as digital infrastructure by selling heavy industrial generators to power-starved data centers.

Physical constraints and raw hardware scarcity are officially becoming the primary bottlenecks restricting downstream profitability.
