Amazon revealed its custom chip business generates over $20 billion annually, growing at triple-digit rates. CEO Andy Jassy disclosed in his shareholder letter that AWS AI revenue reached a $15 billion run rate in Q1 2026, while defending the company's $200 billion capital expenditure plan. The tech giant may soon sell its Trainium and Graviton chips directly to third parties.

Amazon Reveals Massive Scale of Custom Chip Business

Amazon AI has reached a pivotal moment as the company disclosed that its custom chip business now generates over $20 billion in annual revenue, doubling from the $10 billion milestone reported earlier this year

2

. CEO Andy Jassy revealed in his annual shareholder letter that the business is growing at triple-digit percentage rates year-on-year, encompassing the company's Graviton, Trainium, and Nitro chip lines

. The disclosure offers a rare glimpse into the scale of Amazon's in-house chip operation, which produces general-purpose computing and AI accelerators designed to make the company's servers run more efficiently

Jassy went further, stating that if Amazon's custom chip business were an independent company selling semiconductors on the open market like Nvidia, it would generate roughly $50 billion in annual revenue

1

. Currently, the company only monetizes these AI chips through its EC2 cloud computing service within AWS, but that model may be about to change

Selling AI Chips Externally Becomes a Realistic Possibility

The demand for Amazon's custom chips has become so intense that Jassy signaled the company may begin selling AI chips to third parties. "There's so much demand for our chips that it's quite possible we'll sell racks of them to third parties in the future," Jassy wrote in his shareholder letter

. This potential shift would follow Amazon's established playbook of building capabilities internally before offering them as external services, the same pattern that created AWS and Fulfillment by Amazon

The appetite for Amazon's silicon is evident in customer behavior. Two large AWS customers asked whether they could purchase all available Graviton capacity for 2026, a request Amazon declined

5

. Graviton, Amazon's custom CPU, now delivers more than 40% better price-performance than comparable x86 processors and is used by 98% of the top 1,000 EC2 customers

4

. Meanwhile, Trainium2 has largely sold out, Trainium3 is nearly fully subscribed, and Trainium4—still approximately 18 months from broad availability—has already been significantly reserved

AWS AI Revenue Run Rate Exceeds $15 Billion

In another significant disclosure, Jassy revealed that AWS's AI revenue run rate exceeded $15 billion in the first quarter of 2026, marking the company's first public statement of direct financial returns from its artificial intelligence efforts

These numbers are "ascending rapidly," Jassy noted, while adding that AWS as a whole would be growing even faster without the capacity constraints currently facing the tech industry

2

. To contextualize this figure, AWS overall had a $142 billion revenue run rate as of Q4 2025

5

.

Jassy positioned Amazon AI as being "smack in the middle of this land rush," comparing the current wave to the early days of cloud computing. Three years after AWS launched commercially, the cloud division had a $58 million revenue run rate. Three years after generative AI took off, the company's AI business is nearly 260 times greater

5

. "We have never seen a technology more quickly adopted than AI," he wrote

Andy Jassy Defends $200 Billion Capital Expenditure Plan

The revelations come as Andy Jassy mounted a vigorous defense of Amazon's $200 billion capital expenditure plan for 2026, with the lion's share directed toward AI infrastructure investment including data centers, chips, and networking equipment

3

. This represents nearly a 60% increase from last year and exceeds the spending of any tech peer

3

. Amazon shares have struggled this year as investors question the aggressive spending plans and grow impatient about when the investments will pay off, with the stock sliding more than 4% year to date

3

.

"We're not investing approximately $200 billion in capex in 2026 on a hunch," Jassy wrote. "We're not going to be conservative in how we play this—we're investing to be the meaningful leader, and our future business, operating income, and free cash flow will be much larger because of it"

3

. He readily acknowledged that Amazon's free cash flow dropped from $38 billion to $11 billion last year, driven by a $50.7 billion increase in capital spending

5

.

The defense rests on committed customer demand rather than speculation. A substantial portion of the expected 2026 CapEx already has customer backing, including OpenAI's commitment of more than $100 billion to AWS, which expanded an existing $38 billion seven-year partnership

4

. This commitment includes OpenAI consuming approximately two gigawatts of Trainium capacity through AWS infrastructure

.

Trainium Chips Position Amazon as Nvidia Alternative

Trainium chips represent Amazon's most direct response to Nvidia's market dominance in AI accelerators. Trainium2 offers roughly 30% better price-performance than comparable GPU alternatives, while Trainium3 provides a further 30 to 40% improvement over Trainium2

4

. Major customers like Uber have already moved workloads onto Trainium3, which began shipping in early 2026

4

.

At scale, Jassy projects that Trainium will "save us tens of billions of capex dollars per year, and provide several hundred basis points of operating margin advantage versus relying on others' chips for inference"

5

. Notably, Trainium4 will feature interoperability with Nvidia's NVLink Fusion interconnect technology, allowing customers to combine Trainium accelerators with Nvidia GPUs within the same system

4

. Jassy carefully framed the competitive dynamic: "We have a strong partnership with NVIDIA, will always have customers who choose to run NVIDIA," while asserting that "virtually all AI thus far has been done on NVIDIA chips, but a new shift has started"
