Amazon has committed up to $25 billion in additional funding for AI startup Anthropic, bringing its total investment to $33 billion. In return, Anthropic pledges to spend over $100 billion on Amazon Web Services over the next decade.
The expanded partnership deepens Amazon's involvement in the artificial intelligence sector and secures a major long-term customer for its cloud division.
Amazon's initial $8 billion investment in Anthropic was announced in September 2023. The new commitment increases the tech giant's stake substantially, positioning it as a major backer of the Claude AI model developer.
Under the terms of the agreement, Anthropic commits to spending $100 billion or more on AWS infrastructure and services over the next 10 years. This arrangement ties Anthropic's computational needs directly to Amazon's cloud platform and represents a significant revenue stream for AWS.
Anthropicachieves a valuation of $60 billion following this funding round. The company, founded in 2021 by former OpenAI executives including Dario Amodei and Daniela Amodei, has emerged as a leading AI safety-focused competitor to OpenAI and Google's Gemini.
The investment includes provisions that allow Amazon to integrate Anthropic's technology into its own products and services. Amazon has already begun offering Claude through its Bedrock generative AI platform.
For Anthropic, the funding provides substantial capital to develop and scale its AI models while maintaining operational independence. The company has also received significant backing from other investors, including Google, which has committed up to $2 billion.
The deal reflects intensifying competition in the generative AI market, where companies are securing both AI talent and computational resources. Amazon's escalating investment signals confidence in Anthropic's technology and business trajectory while simultaneously locking in computing demand for years ahead.
Both companies are scheduled to provide additional details about the partnership structure in coming announcements.
Z.ai released GLM-5.3's weights on Hugging Face under a new license that requires large companies to undergo security review before hosting the model. The change marks a departure from the standard MIT license.
Anthropic has introduced the Model Hardware Standard (MHS), a unified interface enabling AI agents to operate robotic arms, lab instruments, and other physical devices. Early testing shows integration time has dropped from weeks to hours.
Open-weight AI companies—those releasing freely available models—are attracting major acquisition interest from tech giants. The trend reflects growing capital investment in the business model of distributing AI models at no cost.
Google Deepmind has upgraded its Co-Scientist AI system to autonomously plan experiments, operate lab equipment, and publish scientific papers. The Gemini-based multi-agent platform demonstrated experimentally validated results across materials science, chemistry, and medical AI development.
