U.S. AI Agents Market Summary

The U.S. AI agents market size was estimated at USD 1,603.0 million in 2024 and is projected to grow at an impressive compound annual growth rate (CAGR) of 43.3% from 2025 to 2030. The growing integration of AI agents with cloud platforms reflects the increasing demand for scalable, flexible deployment models. Cloud infrastructure offers streamlined management of AI agents across multiple operating environments and ensures seamless connectivity with enterprise data sources and IT systems. Furthermore, cloud-based delivery supports continuous updates and maintenance, reducing operational complexity.

For instance, in May 2025, IBM Corporation and Amazon Web Services, Inc., a U.S.-based cloud computing firm, expanded their collaboration to deliver agentic AI capabilities. Their integration of Amazon Q Index with IBM Watson Orchestrate facilitates the development of personalized, enterprise-grade AI solutions. IBM is also advancing its Granite 3.2 models, governance tools, and automation software offerings through the AWS Marketplace to help organizations deploy scalable and trustworthy AI agents.

AI agent marketplaces are becoming an important trend in the rapidly evolving AI sector. These digital platforms enable users to design and deploy AI agents tailored to specific tasks or industry needs. They support a high degree of customization, empowering users to build function-specific agents that address niche requirements. Once developed, these agents can be distributed through the marketplace, promoting solution reuse, innovation sharing, and faster adoption. This model accelerates development cycles and simplifies deployment.

For example, in January 2025, Hippocratic AI, a healthcare technology firm, launched its Healthcare AI Agent App Store. This platform enables clinicians to develop customized AI agents for patient care in under 30 minutes. The initiative allows medical professionals to tackle operational inefficiencies while participating in revenue generation. The model includes thorough safety testing and direct clinician involvement, aiming to enhance patient outcomes and establish a collaborative ecosystem for AI innovation in healthcare.
