AWS Server Capacity Largely Sold Out Through 2027, Andy Jassy Says

In short

• Amazon CEO Andy Jassy stated that AWS cloud server capacity is sold out for 2026 and largely committed through 2027, with significant blocks taken for 2028.
• Amazon plans to spend about $220 billion on capital expenditure in 2026.
• The company has disclosed over $225 billion in future Trainium chip commitments, including deals with Anthropic and OpenAI, to help lower the cost of AI inference.

Amazon CEO Andy Jassy announced that AWS server capacity is largely booked years in advance, with major blocks of cloud computing infrastructure spoken for through 2027 and extending into 2028. Speaking on an Andreessen Horowitz video podcast on Friday, October 23, 2026, Jassy stated that the platform faces persistent demand from artificial intelligence labs and enterprise customers. Amazon Web Services continues to add capacity globally, but customer orders have outstripped available supply across multi-year planning horizons.

Noting that cloud-computing capacity for 2026 is already sold out, Jassy said, "2027 is largely sold out. We always leave a certain amount for on demand and our inference service bedrock, or EC2, but largely sold out all the big chunks. A good chunk of 2028 is sold out," during the interview with Andreessen Horowitz co-founder Ben Horowitz and general partner Erik Torenberg, as reported by Reuters via Investing.com.

Sold Out Cloud Infrastructure Stretches Into 2028

According to Jassy, the constraints stem from what he described as insatiable appetite from AI laboratories that are consuming massive volumes of computing resources. AWS reserves baseline capacity for on-demand Elastic Compute Cloud (EC2) servers and its Bedrock generative AI managed service, ensuring smaller organizations and existing workloads retain access. However, large allocations dedicated to specialized AI training and heavy inference workloads are committed years out, according to reporting by 24/7 Wall St..

Amazon has not publicly disclosed exact contracted backlog numbers or specific capacity metrics underlying Jassy's comments. Nevertheless, Jassy indicated that supply limits will not abate quickly, stating, "I don't think that that shortage ends in 2027." With major capacity blocks locked into forward commitments, AWS revenue growth relies directly on how rapidly the company can build data centers and secure silicon, electrical power, and memory.

The cloud provider's recent financial results reflect that acceleration. AWS posted second-quarter 2026 revenue of $42.2 billion, marking a 37% year-over-year increase—its fastest pace in 18 quarters—and bringing its annualized revenue run rate to $169 billion, according to 24/7 Wall St..

Trainium Chips Target High AI Inference Costs

To address computing bottlenecks and operating expenses, Amazon has turned to custom silicon designed by Annapurna Labs, which Amazon acquired approximately ten years ago. Jassy highlighted the acquisition as potentially the best in Amazon's corporate history, noting its role in creating proprietary Graviton server CPUs and Trainium AI accelerators, according to the Maeil Business Newspaper.

Jassy explained that running model queries remains inefficient across the industry, stating that AI inference is "an order of magnitude too expensive in my opinion for it to be used as pervasively as possible." Andy Jassy has been reported as saying Trainium delivers about 30% to 40% better price-performance than comparable processors. Amazon has already accumulated more than $225 billion in forward Trainium revenue commitments, supported by high-profile deals with developers including Anthropic and OpenAI, as noted by 24/7 Wall St..

In addition to hardware design, Amazon is expanding its international footprint to support compute-heavy customers. In South Korea, AWS is constructing a 100-megawatt AI data center in Ulsan in partnership with SK Group, with phased commercial operations scheduled to begin in the second half of 2027, according to the Maeil Business Newspaper.

Heavy Capital Spending Meets Capacity Limits

Supporting this expansion requires substantial capital deployment. Earlier in 2026, Amazon announced it would allocate approximately $220 billion to capital expenditures for the year, as reported by Reuters via Investing.com. Jassy observed on the podcast that the company "could invest a lot more and it wouldn't be a bad use of capital."

That spending has created financial trade-offs. Over the trailing twelve months, Amazon's property and equipment purchases climbed by $66.1 billion, which Amazon said primarily reflects investments in artificial intelligence, leaving trailing free cash flow at an outflow of $7.6 billion, according to 24/7 Wall St.. Furthermore, because significant capacity blocks are tied to leading AI labs, future financial stability depends on the sustained funding and software unit economics of those key customers.

Amazon shares closed Friday, October 23, 2026, at $248.00, down 0.95%, representing a market capitalization of roughly $2.68 trillion, before rising slightly to $248.80 in after-hours trading. Investors will receive an updated look at cloud growth and financial performance when Amazon reports its third-quarter earnings on Thursday, October 29, 2026. Official guidance projects third-quarter net sales between $197.0 billion and $202.0 billion and operating income between $22.5 billion and $26.5 billion.

Questions people ask

Is AWS completely out of computing capacity for new customers?

No. While Andy Jassy stated that large blocks of server capacity are sold out through 2027, AWS reserves capacity for on-demand EC2 workloads and its Bedrock AI inference service to support regular business operations.

How much is Amazon investing in cloud and AI infrastructure in 2026?

Amazon stated earlier in 2026 that it plans to spend about $220 billion in capital expenditures for the year.

What role do Amazon's proprietary Trainium chips play?

Andy Jassy has been reported as saying Trainium delivers about 30% to 40% better price-performance than comparable processors. Amazon has disclosed over $225 billion in forward Trainium revenue commitments from clients such as Anthropic and OpenAI.
