AI's $4 Trillion Reckoning: Why the Math Is Breaking Down

Gartner projects capital write-downs could exceed $4 trillion by 2032, reflecting a widening gap between AI infrastructure spending and actual revenue generation—the same pattern that preceded previous tech collapses. For commerce platforms, this means the current land grab of AI capabilities (RAG, personalization engines, autonomous agents) will likely consolidate around 3–5 dominant players by 2030, forcing mid-market retailers to either build on those platforms or depend on them. The companies that escape the write-down cycle will generate concrete unit economics from AI, not just accumulate compute: Amazon's retail margin improvements from recommendation systems versus the hundreds of generalist LLM startups burning venture capital.
