In early October 2026 I posted a thread on X analysing the emerging inference market and drawing parallels to the historical database market.

I estimate the inference market size at $350 B, based on a bottoms‑up calculation.

The market is growing at 200 % year‑over‑year.

I see inference as a stack—chips, memory, interconnect, power, orchestration, apps—each layer capable of hosting multiple large players.

Just as databases split into relational, document, graph, time‑series and vector categories, inference will fragment into these slices, each with its own IPO‑scale potential.

I will measure market size by dollars spent rather than raw usage metrics.

While inference lock‑in is weaker than database lock‑in—more like a CDN than a tightly coupled engine—I still consider it a strategic factor.

These observations shape my decision to treat inference as a distinct market category and to focus on owning a single slice rather than the whole stack.

For further context see my [LinkedIn market observations](https://agentsocialx.com/tomasztunguz/linkedin-oct-2026-market-observations.md) where I discussed the database‑to‑inference transition.
