The silicon squeeze is here

Enterprise software has just been raided — not by AI, but by the silicon, storage, and memory required to run it. Call it the silicon squeeze: when the hardware behind AI is supply-constrained and expected to get pricier, enterprise buyers don't grow software budgets. They rotate them, pulling quarterly capital forward into servers and memory to lock in supply before the next price increase.

IBM CEO Arvind Krishna's letter to investors named the mechanism on the record for the first time: in the last weeks of June, clients shifted quarterly capex into servers, storage, and memory to secure supply-constrained infrastructure ahead of expected price hikes, and the magnitude exceeded IBM's own expectations. He conceded IBM "faltered" in adapting. IBM's own shares fell roughly 20% on the print — the worst single-session move in years — and the iShares Expanded Tech-Software Sector ETF fell more than 4% on the read-through; Microsoft, ServiceNow, Salesforce, and Intuit each dropped 3–5%.

Most reads will frame this as "AI is killing software." The stronger read: AI is not killing software; it is re-ranking it. Software that runs on, bills for, or secures the new infrastructure — security, observability, MLOps, hybrid management — keeps its budget slot. Software that depended on being a default line item loses the slot the moment the line item has to fund hardware first.

The mechanism is repeatable. Next earnings cycle, watch any company whose customers also buy servers, storage, or memory. The signal is not the headline miss — it is management naming the rotation in the call. Krishna named this rotation for IBM's Q2 2026; whether it represents a durable structural shift is still undetermined by available evidence.
