Amazon Integrates OpenAI Models into AWS Bedrock as Big Tech Prepares Earnings Reports

Amazon revealed that OpenAI's models would be available on its AWS cloud computing service, expanding options for users through the Bedrock service where they can now access both OpenAI's flagship models and those from Anthropic, a partner since 2023.

The announcement came a day after OpenAI and Microsoft disclosed a shake-up to their partnership, with Microsoft having invested a total of $13 billion in OpenAI and Amazon committing $50 billion. Shares of Oracle, Nvidia, Advanced Micro Devices, and Broadcom sank following a Wall Street Journal report that OpenAI missed revenue and user growth projections, which also suggested OpenAI leaders are worried about the company's ability to keep pace with massive financial commitments tied to building out data centers.

A Crossmark Global Investments strategist described Alphabet and Amazon as strong performers in the recent Big Tech earnings, noting they stood out this season. The earnings season covers reports from the first quarter of 2026.

Amazon, Alphabet, Meta, and Microsoft were set to report quarterly earnings after the close, with all having ties to OpenAI as investor, customer, strategic partner, competitor, or some combination. KeyBanc analysts called the launch positive for AWS customers gaining access to OpenAI and Anthropic models, while maintaining a buy recommendation on Amazon stock.

Raymond James analysts wrote that investors are increasingly concerned about Microsoft's reliance on OpenAI and that OpenAI is diversifying its compute away from Microsoft, while maintaining the equivalent of a buy rating on Microsoft stock.

Alphabet, the parent company of Google, is competing with OpenAI through its Gemini models and Gemini-powered services, with its shares having more than doubled in the past year as Google's cloud business has boomed due to demand for compute capacity.
