Anthropic's $11.6 billion Akamai deal — it bought CPUs, not GPUs
Anthropic has committed to spend 11.6 billion dollars over seven years on Akamai's cloud, Akamai announced on September 24, 2026. It is more than six times the 1.8 billion dollar deal reported in May and the largest contract in Akamai's history. What Anthropic is buying is CPU capacity, not the GPUs used to train models: the general-purpose computing that AI agents burn through when they call tools, read the web and run code. The deal can expand by up to 9 billion dollars to about 20 billion, Anthropic received a warrant for up to about 5 percent of Akamai at 111.33 dollars a share, and Akamai will spend about 5.5 billion dollars building the capacity
The three lines
- Size — 11.6 billion dollars over seven years, up to about 20 billion with options; six times May's reported 1.8 billion; Akamai's largest ever
- What — CPU capacity, not GPUs: the compute agents use to run tools, browsers and code, a demand curve separate from training
- Terms — a warrant for up to about 5% of Akamai at 111.33 dollars a share; Akamai spends about 5.5 billion dollars in capex before revenue arrives
Key questions
- How big is the Anthropic Akamai deal
- **11.6 billion dollars committed over seven years, about 20 billion with options.** | Item | Detail | |---|---| | Committed | **11.6 billion dollars**, seven years | | Expansion option | up to **9 billion dollars** more, about 20 billion total | | Prior deal | **1.8 billion dollars**, reported by Bloomberg in May | | Akamai capex for the deal | about **5.5 billion dollars**; 2026 capex raised about 1.7 billion for memory and other parts | | Akamai revenue timing | none in 2026; 150–300 million dollars from the second half of 2027; about a 1.7 billion annual pace by end-2028 (TechCrunch) | Akamai called it the largest contract in its history.
- Why is Anthropic buying CPUs instead of GPUs
- **Training a model and running an agent need different chips.** | Work | Main chip | Example | |---|---|---| | Training | GPUs, AI accelerators | tens of thousands of chips for months | | Inference | GPUs, AI accelerators | generating tokens | | Agent execution | **CPUs** | running code, opening browsers, editing files, calling tools | TechCrunch wrote that the deal reflects **growing CPU demand as AI agents take on more tasks.** An agent does its thinking on GPUs, but the sandboxes where it acts run on CPUs, and one task can mean hundreds of such steps. AMD's run to a 1 trillion dollar valuation this year was also driven by server CPUs rather than GPUs.
- What is the Akamai warrant Anthropic received
- **A right to buy Akamai shares at a set price, which grows as Anthropic spends more.** | Term | Detail | |---|---| | Instrument | nonvoting preferred stock convertible into **7.7 million** common shares | | Exercise price | **111.33 dollars** a share | | Maximum | about **5%** of Akamai | | First tranche | about **2%** | | Further tranches | about **1%** per additional 3 billion dollars committed | TechCrunch noted the structure mirrors AMD's 2025 arrangement with OpenAI. **A supplier hands a big customer equity to lock in long-term demand.** The more the customer spends, the more the supplier's stock may rise, and the customer shares in that gain.
Anthropic just put 11.6 billion dollars not on the chips that build models, but on the chips that let models work. Akamai announced on September 24, 2026 that Anthropic had signed a seven-year cloud contract, the largest in Akamai's history.
1. The numbers
| Item | Figure | Note |
|---|---|---|
| Committed | 11.6 billion dollars | seven years |
| Expansion option | up to 9 billion dollars | about 20 billion combined |
| Deal reported in May | 1.8 billion dollars | this is 6x larger |
| Akamai capex | about 5.5 billion dollars | spent before revenue |
| 2026 capex increase | about 1.7 billion dollars | memory and components |
| Anthropic warrant | up to about 5% of Akamai | at 111.33 dollars a share |
Akamai said there is no revenue impact in 2026. According to TechCrunch, revenue starts at 150–300 million dollars in the second half of 2027 and reaches an annual pace of about 1.7 billion dollars by the end of 2028. Akamai spends first and gets paid a year later.
2. Why CPUs — agents are expensive to run, not just to think
Most AI infrastructure headlines have been about GPUs. This one is not. Akamai's release describes the purpose as supporting Anthropic's accelerating CPU workload demands.
| Stage | What happens | Main chip |
|---|---|---|
| Training | build the model | GPUs, accelerators |
| Inference | generate the answer | GPUs, accelerators |
| Agent execution | run code, open browsers, edit files, call tools | CPUs |
When an agent is asked to fix a bug, deciding what to do happens on GPUs, but running the tests and opening the files happens in an isolated sandbox on CPUs. One task can repeat that loop dozens or hundreds of times. As agents multiply, CPU demand grows on its own curve, separate from GPUs.
The trend was already visible. AMD crossed a 1 trillion dollar market value this year after a 180% rise, with server CPUs, not GPUs, cited as the driver. OpenAI was reported to have bought tens of thousands of Macs for computer-use agents rather than more GPUs.
Why Akamai. Akamai built its business by scattering servers around the world to deliver web pages and video from nearby. At the end of 2025 it had more than 4,300 points of presence in over 130 countries. Its strategy is to turn that distributed network into AI compute, and this deal is the first large-scale validation of that bet.
3. The warrant — a customer becomes a shareholder
| Term | Detail |
|---|---|
| Form | nonvoting preferred, convertible into 7.7 million common shares |
| Exercise price | 111.33 dollars a share |
| First tranche | about 2% |
| Additional | about 1% per extra 3 billion dollars committed |
| Maximum | about 5% |
The more Anthropic spends on Akamai, the more of Akamai it can own. If Akamai's stock rises above the strike price, Anthropic keeps the difference, effectively getting some of its cloud bill back in equity. The structure resembles AMD's 2025 deal with OpenAI.
Markets treated it as an Akamai story, not a sector story. Akamai rose as much as 17% after hours and about 15% early on September 25 (TechCrunch, 24/7 Wall St.), while peers such as CoreWeave and Cloudflare gained only about 1% early in the session.
4. Anthropic's compute map
Anthropic already has investment or compute commitments from Amazon, Google, Microsoft and AMD (TechCrunch). Now it has a dedicated CPU supplier as well. The same week it released Claude Opus 5.5 and entered a price war with OpenAI's GPT-6 Sol. Cutting prices while widening use means securing the cost that will grow fastest: running agents.
5. What remains unconfirmed
- The vesting trigger for the first ~2% differs between Akamai's release (on announcement) and TechCrunch (on first payment).
- Akamai's closing price on September 25 was not cross-checked.
- Anthropic has not said which products will use the capacity.
- Akamai is spending 5.5 billion dollars ahead of revenue. If agent demand grows more slowly than expected, the capacity becomes Akamai's burden.
