New York, February 28, 2026, 10:02 EST — Market shut for the day.
- Amazon ended Friday up 1% at $210, outperforming the softer broader market.
- OpenAI announced that Amazon is set to invest $50 billion in its newest funding round, with AWS stepping up its involvement in OpenAI’s enterprise platform.
- Next week, investors are eyeing the results of AI spending and keeping tabs on the March 6 U.S. jobs report.
Amazon.com Inc (AMZN) ended Friday at $210, up 1%. Investors are eyeing a new OpenAI partnership that has the potential to boost demand for both Amazon Web Services and its Trainium chips.
Timing is crucial here, since investor nerves are jangling over which players might benefit and which could end up footing the bill as AI makes its way deeper into enterprise tech and infrastructure. “There continues to be this … back and forth” over likely victims and winners, Kristina Hooper, chief market strategist at Man Group, told Reuters.

OpenAI is going after $110 billion in new funding, a move that would put the ChatGPT developer’s valuation at $840 billion. Amazon is in for $50 billion, joining Nvidia and SoftBank in the round. The agreement calls for OpenAI to tap about 2 gigawatts of capacity using Trainium chips—a metric that tracks datacenter-scale compute—while AWS lands exclusive rights as third-party cloud provider for OpenAI Frontier. That “AI agents” platform is designed to help companies automate actions across various tools and systems. Reuters
Amazon detailed the structure in a filing. According to the document, a wholly owned Amazon subsidiary agreed to an equity commitment for $35 billion in OpenAI Series C preferred shares, guaranteeing the full amount. That’s in addition to a separate $15 billion Series C investment that Amazon says it must purchase by March 31, 2026, pending closing conditions. The filing specifies that the $35 billion commitment can be tapped gradually, but it becomes binding once certain milestones are reached or if OpenAI goes public in the U.S., with a final cutoff set for Dec. 31, 2028.
Speaking to CNBC in an interview posted on Amazon’s website, CEO Andy Jassy called the AI race “so early” and touted Trainium’s “30 to 40% better price performance.” He added that he expects the investment to “yield a good return” over time. Amazon News
OpenAI said it and AWS are adding $100 billion to their prior $38 billion deal, stretching the expanded agreement over eight years. The company expects to roll out a “stateful runtime environment” soon—within the next few months—aimed at letting models retain context and memory for longer-running tasks. OpenAI is also teaming up with Amazon to build custom models for Amazon’s own customer applications. OpenAI
Amazon managed to notch a gain despite a volatile day across big tech, as investors continued to question if lofty valuations make sense without quicker AI payoffs. “A lot of good news” is already baked in for semiconductors, so “now it’s time for a breather,” said Talley Leger, chief market strategist at The Wealth Consulting Group.

This isn’t just a hypothetical worry. When Amazon laid out plans for roughly $200 billion in capital spending for 2026—more than 50% higher than its 2025 estimate—shares dropped hard. Investors balked, unsure about the timing of returns from all that AI infrastructure spending.
But even with OpenAI in the fold, Amazon faces a tricky juggling act: riding the promise of extended cloud demand, while also staring down renewed “show me” doubts if AI growth sputters or customers pull back on spending. AWS and its custom silicon may eventually benefit from the extra capacity commitment, but those gains don’t show up right away. That gap is where sentiment can falter.
U.S. markets won’t reopen until Monday, leaving AMZN in focus: will the OpenAI agreement weigh on margins in the short term, or does it set up a future boost for AWS? Eyes now turn to the U.S. February jobs report, scheduled for March 6 at 8:30 a.m. ET—a release known for jolting both rate bets and multiples on growth names.
