Market Size Projection
Overview
The serving layer that turns trained models into production tokens: managed inference APIs, custom model deployment, and GPU neoclouds that undercut closed-model pricing. The AI inference server market sits at $18.31B in 2026 and is projected to reach $93.53B by 2035 at 18.9% CAGR. Capital concentrated fast in mid-2026. Fireworks AI raised a $1.505B Series D at a $17.5B valuation on more than $1B of annualized revenue, Together AI closed $800M at $8.3B on $1.15B of annual bookings, and Groq raised $650M. The buying logic is cost, not capability: Together AI customers cut enterprise inference costs by up to 60x versus closed-model alternatives, and open-weight usage tripled over the year.
