It took less than a week at the start of 2026 for three of the world’s largest technology companies to each announce dedicated health AI products. The rush has not slowed since.
OpenAI, Anthropic and Amazon all debuted consumer and enterprise health AI tools in January. Microsoft followed in March. Epic Systems unveiled a sweeping new AI roadmap at the annual Healthcare Information and Management Systems Society conference in Las Vegas. Oracle Health, formerly Cerner, pressed ahead with expanding its Clinical AI Agent tool.
The convergence has drawn comparisons to the early years of the smartphone era, when platform wars reshaped entire industries in a matter of months. More than 40 million Americans already ask ChatGPT health-related questions each day, according to a January report OpenAI shared with Becker’s.
OpenAI
OpenAI fired the first major move of 2026 on Jan. 7, when it unveiled ChatGPT Health, a dedicated, encrypted space inside ChatGPT where users can connect their medical records and wellness applications for personalized health guidance. The company said it worked with more than 260 physicians across 60 countries and dozens of specialties over two years. Those clinicians reviewed model outputs more than 600,000 times to help shape the product.
The following day, Jan. 8, OpenAI launched a separate enterprise offering called ChatGPT for Healthcare, a workspace designed for researchers, clinicians and administrators that runs on GPT-5 models and maintains compliance with HIPAA. Becker’s reported that early adopters included Boston Children’s Hospital; Cedars-Sinai Medical Center; Stanford Medicine Children’s Health; AdventHealth, based in Altamonte Springs, Fla.; HCA Healthcare, based in Nashville, Tenn.; Baylor Scott & White Health, based in Dallas; Memorial Sloan Kettering Cancer Center; and University of California San Francisco.
OpenAI said it would not train its models on personal medical data.
Anthropic
Anthropic rolled out Claude for Healthcare on Jan. 11 offering HIPAA-compliant tools aimed at prior authorization, patient care coordination and regulatory submissions. The platform connects to CMS coverage databases, ICD-10 codes and the National Provider Identifier Registry, and supports FHIR development and patient message triage.
Anthropic also expanded its Claude for Life Sciences platform to assist with clinical trial protocols and regulatory submissions. Phoenix-based Banner Health was among early adopters, using Claude to build BannerWise, an internal AI platform deployed to more than 55,000 employees across six states.
Amazon
Amazon launched Health AI for One Medical members Jan. 22, using large language models built on its Amazon Bedrock service. The tool answers health questions, books appointments, manages prescription renewals and provides personalized guidance by referencing patients’ medical records through the nationwide Health Information Exchange. The company expanded the tool to Amazon.com and the Amazon app March 10, making it available to any U.S. customer regardless of whether they hold a Prime or One Medical membership.
Health AI connects to One Medical’s network of primary care clinics, allowing the tool to route users to licensed providers through in-app messaging, video visits or in-person appointments when clinical judgment is needed. The system uses a multi-agent architecture: core agents handle patient communication, sub-agents execute specific tasks such as retrieving lab results and auditor and sentinel agents monitor conversations in real time, escalating to human clinicians when needed.
The tool does not add conversations to patients’ medical records. Amazon said protected health information is not used to market general merchandise through its broader retail platform.
Microsoft
Microsoft announced Copilot Health on March 12, entering the consumer health AI market roughly two months after OpenAI and Anthropic. The service lets users upload EHRs and data from fitness trackers and wearable devices, then uses the combined information to generate personalized insights. Copilot Health can draw on records from more than 50,000 U.S. health providers and data from 50 types of wearable devices, the company said.
Epic
At HIMSS 2026 in Las Vegas, Epic Systems presented its AI roadmap.
More than 85% of Epic’s customers now use Epic AI, the company said. The centerpiece HIMSS announcement was Agent Factory, a no-code platform that lets health systems design and deploy their own AI agents across clinical, administrative and operational workflows. Charlotte, N.C.-based Advocate Health has been using the platform.
Epic has also released three named AI agents: Art, which helps clinicians document patient visits and generate discharge summaries; Penny, which handles revenue cycle tasks including prior authorization and coding; and Emmie, a patient-facing assistant for scheduling, lab result explanations and general health questions.
On Feb. 4, the company rolled out AI Charting, a built-in ambient documentation tool that listens during patient visits and drafts clinicians’ notes and suggested orders in real time.
Oracle Health
Oracle Health launched its Clinical AI Agent note generation tool for inpatient and emergency department settings in the U.S. in March.
The tool automatically generates draft clinical notes by organizing symptoms, treatments and other encounter details into a single document clinicians can review, edit and sign.
The announcements mark a significant shift in how major technology companies are approaching healthcare.
At the Becker's 11th Annual IT + Revenue Cycle Conference: The Future of AI & Digital Health, taking place September 14–17 in Chicago, healthcare executives and digital leaders from across the country will come together to explore how AI, interoperability, cybersecurity, and revenue cycle innovation are transforming care delivery, strengthening financial performance, and driving the next era of digital health.
