Amazon stock jumps 5% on OpenAI’s $38B AWS deal

Amazon shares rallied after OpenAI unveiled a sweeping cloud pact with Amazon Web Services. OpenAI struck a $38 billion, seven-year AWS cloud partnership, giving the ChatGPT maker immediate access to massive computing power and signaling a broader reshaping of the AI infrastructure race.

What changed

Announced on November 3, 2025, the agreement lets OpenAI run core AI workloads on AWS right away, tapping clusters built with hundreds of thousands of Nvidia GPUs and the ability to scale to tens of millions of CPUs over time. Amazon says capacity is targeted to come online before the end of 2026, with room to expand in 2027 and beyond. OpenAI gets immediate access to Nvidia-powered AWS compute, including GB200 and GB300 accelerators in new EC2 UltraServers.

Why it matters

The deal underscores how compute has become the currency of progress in AI. For Amazon, it’s a validation of AWS’s role in the next wave of AI infrastructure—and markets noticed: Amazon shares jumped about 5% to a record high, adding significant market value in Monday’s session. For OpenAI, the arrangement expands its options beyond Microsoft following a restructuring that increased its operational flexibility and, under new terms, removed Microsoft’s first right to supply compute.

Broader context

Both companies cast the pact as a response to exploding demand for reliable, high-scale AI infrastructure. OpenAI’s leadership has talked openly about the need to massively expand computing capacity to train and serve increasingly capable models. Analysts say the AWS tie-up diversifies OpenAI’s supplier base while reinforcing Amazon’s standing against rivals that have leaned on their own AI partnerships.

What’s next

OpenAI is set to begin using AWS immediately, with most planned capacity deployed by late 2026. Investors will watch how quickly workloads transition, what portion of OpenAI’s training and inference ultimately lands on AWS, and whether the partnership spurs further industry capacity buildouts. Capacity targeted before end of 2026, with room to grow, remains the key execution milestone.
