OpenAI and AMD struck a multi-year deal to deploy up to 6 gigawatts of AMD Instinct GPUs, starting with 1GW in the second half of 2026. The first systems will use AMD’s MI450 chips, with a path across future generations. The agreement also includes a warrant giving OpenAI the right to acquire up to 160 million AMD shares if milestones are hit.
The deal gives OpenAI another large lane for compute as demand for training and serving AI models keeps rising. For AMD, it’s a signal win that could be worth “tens of billions” in revenue, depending on execution and market conditions. It also intensifies the GPU race against Nvidia, which still leads in market share and software depth.

What Happened
OpenAI will deploy 6GW of AMD GPU capacity over multiple hardware generations. The initial 1GW rollout is slated for 2H 2026 using the Instinct MI450 series. The companies say they will collaborate across hardware and software roadmaps, building on work that started with MI300X and MI350X.
A financial wrinkle stands out: AMD issued OpenAI a warrant to buy up to 160M shares of AMD common stock at a nominal price, vesting in tranches as deployments scale (and subject to AMD share price targets and technical milestones). Industry coverage pegs the potential stake at around 10% if all conditions are met.
Why it matters
Compute hunger. Training frontier-scale models and running them in production takes vast power and hardware. A single “generation” of models can require multiple new data-center footprints. Committing to 6GW sets the expectation that OpenAI intends to scale capacity in large, predictable blocks over several years.
Vendor diversification. OpenAI already uses Nvidia GPUs and is exploring custom silicon. Adding AMD at multi-gigawatt scale reduces supply risk and pricing exposure and creates leverage across the stack. Markets read it as a competitive milestone for AMD.
Revenue signal. AMD describes the partnership as potentially worth “tens of billions” and says it expects strong earnings impact if milestones are achieved. That sets a performance bar for MI450 deployments and software readiness.
Timeline and hardware
MI450 in 2026. AMD and media reports align on a 2026 deployment window for MI450, with the first 1GW coming in 2H 2026. Prior AMD statements suggested MI450 arrives as Nvidia readies its next nodes (e.g., Rubin-class parts), setting up a direct performance and efficiency comparison.
What does 6GW mean? “Gigawatt” is power capacity, not compute. If you budget 700–1,000 watts per accelerator in a dense rack (not counting cooling and overhead), 1GW could translate to ~1.0–1.4 million GPUs at face value. Real deployments will be lower due to PUE (cooling) and surrounding systems. Treat this as a rough order-of-magnitude guide, not a shipment forecast.
Software stack and developer impact
ROCm and Triton. AMD’s ROCm stack underpins Instinct accelerators, with growing support for AI frameworks. Triton, OpenAI’s GPU kernel language, now works with ROCm, which helps port custom kernels and optimize hot paths outside of CUDA. This matters for inference and for training efficiency when moving workloads from Nvidia.
Migration considerations. Teams moving from CUDA will weigh kernel availability, compiler maturity, memory behavior, and ops tooling. ROCm has matured quickly, but some advanced CUDA-native workflows still require porting or re-tuning. Expect mixed early results by workload LLM inference often moves first; bespoke training code may lag.
Competitive context
Will OpenAI still use Nvidia? Yes. Reporting indicates OpenAI will maintain relationships with Nvidia and continue exploring custom silicon. Large AI platforms typically run multi-vendor fleets for supply, performance, and pricing reasons.
What to watch next.
- MI450 disclosures: TDP, HBM capacity, interconnects, and ROCm features.
- Nvidia’s next parts: Rubin timelines and real-world perf/watt against MI450.
- Software wins: Triton kernel libraries and PyTorch/XLA paths on ROCm for MI450-class systems.
Who gains what near term
| Stakeholder | Likely upside | Likely risk/trade-off |
|---|---|---|
| OpenAI | Added supply lane; pricing leverage; roadmap influence | Migration work; mixed perf early; scheduling to 2026 |
| AMD | Revenue scale (“tens of billions” potential); marquee logo | Must deliver MI450 on time; ROCm maturity under scrutiny |
| Developers | Triton on ROCm; more hardware choice | Porting kernels; tooling differences vs CUDA |
| Nvidia (context) | Pressure to respond on perf/watt, pricing | Retains ecosystem lead; supply still tight in 2025 |
Limitations / what we don’t know yet
- Final MI450 specs, thermals, and perf/watt are not public.
- Real-world PUE and data-center layouts will change the 6GW → GPU count math.
- Warrant vesting depends on technical and stock milestones; outcomes may differ from headline potential.
The Bottom Line
OpenAI will deploy 6GW of AMD Instinct GPUs over multiple generations, starting with 1GW of MI450 in 2H 2026. The agreement includes a warrant for OpenAI to buy up to 160M AMD shares as deployments scale and price targets are met. Expect supply diversification, software work on ROCm/Triton, and a 2026 performance face-off with Nvidia.
Frequently Asked Questions (FAQs)
What is MI450?
AMD’s next-gen Instinct accelerator family expected for 2026 deployments at OpenAI, following MI300/MI350. Final specs aren’t public yet.
How big is 6GW in plain terms?
It’s power capacity. With 700–1,000 W per accelerator as a rough guide, 1GW could imply ~1.0–1.4M GPUs before cooling/overhead; real deployments would be lower. Treat as directional, not exact.
What will developers notice on AMD?
A growing ROCm software stack and Triton support. Many inference paths move cleanly; some custom training kernels need tuning or rewrites.
Is AMD promising a performance lead?
Pre-launch reports suggest AMD targets top-tier performance vs Nvidia’s next cycle; independent benchmarks will tell. Watch real MI450 perf/watt once systems ship.
Why a warrant and not just discounts?
The warrant aligns incentives over time. OpenAI’s ability to exercise depends on deployment, technical, and price milestones, spreading risk and upside between both parties.
Will this affect GPU prices?
Large anchor customers can influence supply and pricing. But broader market demand, yields, and competing launches will matter more in 2026–27.
Featured Answer Boxes
What exactly did OpenAI and AMD agree to?
A multi-year plan to deploy up to 6GW of AMD Instinct GPUs, starting with 1GW of MI450 in 2H 2026. The deal spans multiple chip generations and includes a warrant letting OpenAI buy up to 160M AMD shares if deployment and price milestones are met.
Why is the 6GW figure important?
It signals a multi-year, multi-site buildout. “6 gigawatts” is power capacity, not compute, but it implies millions of accelerators across generations once you include system overhead. It also shows OpenAI is diversifying supply beyond Nvidia at scale.
When will the first systems go live?
OpenAI’s first 1GW of AMD Instinct MI450 systems is slated for the second half of 2026, with additional deployments to follow as milestones are met.
Does this replace Nvidia at OpenAI?
No. Reporting indicates OpenAI will continue using Nvidia and explore custom silicon while adding AMD for scale and supply resilience. Multi-vendor fleets are common in hyperscale AI.
What’s the warrant about?
AMD granted OpenAI a warrant to buy up to 160M AMD shares at a nominal price. Tranches vest when OpenAI deploys AMD systems (from 1GW up to 6GW) and when AMD hits share-price targets, among other milestones.
