Together AI closes $800M Series C led by Aramco at $6.5B valuation on $1.15B ARR
Together AI, an AI infrastructure company providing low-cost inference for open-source and proprietary models, closed an $800m Series C led by Aramco Ventures on July 1, 2026. The funding values Together AI at $6.5bn post-money and caps a competitive funding window: Groq announced a $650m raise the prior week (June 22), giving both companies similar balance sheets and overlapping market positions as dedicated AI inference platforms targeting enterprise developers seeking alternatives to hyperscaler pricing.
Together AI disclosed that annual bookings crossed $1.15bn in Q2 2026, marking exceptional revenue traction for a two-year-old infrastructure company. The company plans to deploy the new capital toward scaling its public cloud inference capacity by a factor of 50 over five years. Aramco's participation signals strategic interest in stable, power-constrained compute supply: the Saudi state oil company's venture arm has been systematically backing AI infrastructure companies whose margin and capacity economics depend on reliable, large-scale power availability—a core competency Aramco possesses.
Together AI competes in a narrowing market segment: both Groq and Together AI pitch dedicated AI inference with lower per-token costs than cloud hyperscalers, both target the same developer base, and both aim to undercut OpenAI API and Anthropic pricing. The announcement timeline (Groq June 22, Together July 1, nine days apart) suggests both companies closed their rounds within the same fundraising cycle, which will accelerate the timeline for customer consolidation and competitive separation.
For enterprise infrastructure teams, Together AI's $1.15bn ARR and public commitment to 50x capacity growth signal that inference cost arbitrage is now a material expense category for teams running production AI workloads. The company’s ability to raise $800m post-close on strong ARR growth suggests investors believe dedicated inference platforms can capture margin from hyperscalers by servicing developers who optimize for cost over full-stack lock-in. Groq and Together AI now occupy the same market position; one will consolidate the other’s customers or the category will commoditize around price.
