IBM, Together AI Sign Multi-Year Deal to Scale Open-Source AI Inference
IBM said it will collaborate with Together AI on a multi-year $240M deal to scale open-source AI inference. Together AI will deploy on IBM Cloud a large cluster of NVIDIA HGX B300 systems, expected in Q1 2027, using Spectrum-X Ethernet. Together AI reported 400 trillion tokens monthly and an $800M Series C at an $8.3B valuation.
How this was made

The 30-second read
Why it matters
For traders, the key is whether this partnership meaningfully changes IBM Cloud’s enterprise AI inference pipeline and whether the $240M commitment is incremental and durable.
Market read
A concrete, multi-year enterprise AI inference infrastructure deal with specific hardware and a defined deployment window, but with limited immediate financial impact.
What to watch
Execution risk on delivering HGX B300 cluster capacity, customer adoption of Together AI’s inference platform, and whether token-economics claims translate into sustained enterprise contracts.
Background
IBM and NVIDIA already collaborate on AI infrastructure and software; this adds a dedicated inference cluster on IBM Cloud using NVIDIA HGX B300 and Spectrum-X networking.
Ticker impact
IBM announced a multi-year $240M collaboration with Together AI to deploy NVIDIA HGX B300 inference capacity on IBM Cloud starting Q1 2027.
Moderate positive bias for IBM on deal credibility, with limited immediate earnings impact until deployment timelines approach.
The article provides deal size ($240M) and deployment timing (expected availability Q1 2027) plus specific NVIDIA hardware/networking, which is actionable for positioning but not an earnings print.
Market effects
Reinforces the enterprise AI inference infrastructure buildout and the shift toward open-source inference stacks on major cloud platforms.
No specific regional demand or policy signal beyond global enterprise AI scaling.
Highlights continued hyperscaler-style partnerships around NVIDIA GPU supply and networking for inference workloads.
Counterpoint
The $240M figure may be more of a capacity/partner arrangement than incremental IBM revenue, and the bulk of impact is deferred to 2027.
