New York, Feb 27, 2026, 16:36 EST — After-hours
- Amazon shares slipped roughly 2.3%, changing hands near $210 in after-hours action.
- Amazon is putting $50 billion into OpenAI, joining a $110 billion funding round.
- Deal terms are under scrutiny from investors, with the next earnings release slated for April 30.
Amazon.com Inc (AMZN.O) slipped roughly 2.3% to about $210 in Friday’s after-hours session, following its announcement of a $50 billion investment in OpenAI. The move ramps up its cloud alliance with the AI developer, reigniting conversation around surging AI-related expenditures.
The timing isn’t great for big tech shares. Lately, investors haven’t hesitated to dump stocks at the first sign of rising costs tied to data centers, chips, or electricity—even when the pitch is that it’ll secure future cloud demand.
Stocks dropped across the board Friday. The Nasdaq shed 0.92% as traders contended with rising AI spending, renewed tariff fears, and a fresh batch of hot inflation numbers. “This is a classic risk-off environment,” said Ryan Detrick, chief market strategist at Carson Group. Reuters
OpenAI is set to pull in $110 billion through its latest funding round, bumping the ChatGPT creator’s valuation up to $840 billion ahead of a potential IPO this year. Amazon is putting $50 billion on the table—though only $15 billion up front, with the rest dependent on certain criteria—while Nvidia and SoftBank are each committing $30 billion. As part of the agreement, OpenAI gets access to 2 gigawatts of compute power, all running on Amazon’s Trainium chips. AWS will handle exclusive third-party cloud duties for OpenAI Frontier, the company’s platform for running and managing AI agents across enterprise software, according to Reuters.
Amazon and OpenAI plan to roll out a “Stateful Runtime Environment,” aiming to help developers maintain context and handle extended workflows. The new framework will show up in Amazon Bedrock, AWS’s toolkit for generative AI app development. The two companies also said they’re bumping up their prior $38 billion deal, now adding $100 billion more over the next eight years. OpenAI’s side of the bargain: it’s set to use around 2 gigawatts of Trainium capacity, including both Trainium3 and the upcoming Trainium4 chips—those should start arriving in 2027, if all goes as planned. OpenAI’s Sam Altman described AI as needing to be “practical and genuinely useful.” From Amazon, Andy Jassy pointed to “lots of developers and companies” ready to tap OpenAI services on AWS.

This deal ramps up an already heated spending contest that’s unsettled investors. Amazon earlier this month flagged a steep rise in capital expenditures for 2026—targeting big outlays for assets like data centers. That’s sparked fresh questions about whether AI revenue will catch up with soaring costs.
There’s still uncertainty around timing. Amazon tied the remaining $35 billion to “conditions,” and, as Reuters pointed out, it’s unclear if Nvidia’s fresh stake simply swaps in for the earlier, bigger pledge.
Competition isn’t fading from the picture. Microsoft is still OpenAI’s primary cloud partner for model APIs. AWS, for its part, needs to prove it can convert distributing Frontier and ramping up Trainium-powered capacity into real billings, not just more infrastructure on the books.
Market participants are eyeing specifics around Amazon’s investment terms and any hints about the pace of OpenAI workloads shifting to Trainium. Investors now have their sights set on April 30 for Amazon’s next earnings report, per Yahoo Finance’s earnings calendar.
