Amazon and Apple just announced their grand AI strategies, and the market responded with the enthusiasm of someone who ordered something on Amazon and it arrived on time—pleasant surprise mixed with deep skepticism about whether it was worth the wait.

Here’s what we learned: both companies are spending astronomical sums on AI infrastructure, confident that their future revenues will justify today’s spending spree. Amazon is doubling down on cloud AI services, betting that enterprises will pay premium prices for models trained on their data. Apple is betting that on-device AI will make iPhones so indispensable that people will upgrade their entire ecosystem every two years instead of every three.

The math works out perfectly—on a whiteboard in a Cupertino conference room.

But here’s the part nobody wants to say out loud: neither company has shown that AI actually makes them more money, not just differently money. Amazon’s margins are already thinner than a MacBook Air. Apple’s services revenue is growing, sure, but not fast enough to justify the capital expenditure they’re about to unleash. They are betting that AI will be the thing that finally breaks the pattern.

Investors are playing along because the alternative—admitting that maybe we don’t need another trillion dollars of compute infrastructure—would crater stock prices. So instead, we get confident presentations about “transformative technology” and “competitive moats,” which is corporate speak for “trust us, we know what we’re doing.”

They probably don’t. But the money is real, and so is the hope. That’s enough for now.
