40 Million Daily Users Turn to AI for Healthcare Advice as Medical Chatbot Market Nears $4.4B by 2030

More than 40 million people worldwide now use ChatGPT daily for healthcare-related advice, with 200 million of the platform’s 800 million weekly users submitting medical queries, according to OpenAI’s latest disclosure.

The data underscores the accelerating shift of AI-powered healthcare tools from pandemic-era experimentation to a parallel access layer for medical information, emerging amid mounting strain on traditional health systems and regulatory frameworks struggling to keep pace.

“AI healthcare chatbots have transitioned from emergency solutions during COVID-19 into permanent infrastructure for medical information access,” digital health policy analysts note, “even as questions around accuracy, liability, and patient safety remain unresolved.”

Market Dynamics: From Experimental to Essential

The global healthcare chatbot market reached US$1.2 billion in 2024 and is projected to grow to US$4.4 billion by 2030, representing a 24% compound annual growth rate, according to Grand View Research. AI-based chatbots are expected to handle nearly 75% of routine healthcare inquiries, reshaping how patients access information and triage care.

Usage data highlights consistent patterns: more than half of health-related queries involve symptom exploration, while others focus on medical terminology, treatment options, or insurance navigation. Nearly 2 million weekly interactions relate to billing and coverage—underscoring persistent system complexity, particularly in the United States.

Notably, 70% of healthcare AI interactions occur outside normal clinic hours, with hundreds of thousands of daily inquiries originating from areas lacking timely access to hospitals. These trends suggest AI tools are increasingly filling structural access gaps for time-constrained and underserved populations.

Adoption Accelerates, Unevenly

Healthcare AI adoption has expanded rapidly. In 2025, 66% of physicians reported using health AI, up from 38% in 2023, while 82% of healthcare organizations cited moderate to high returns on investment.

North America remains the largest market, accounting for 31.1% of global healthcare chatbot revenue, driven largely by administrative automation and clinical documentation. Europe shows parallel momentum, with AI increasingly embedded in public health systems, while Asia-Pacific represents the fastest-growing region, led by South Korea.

Clinical Impact and Economic Rationale

More than 340 FDA-approved AI tools are currently in clinical use, primarily for diagnostic applications such as stroke detection and cancer screening. Administrative AI continues to deliver the strongest results, with average returns of US$3.20 for every US$1 invested and payback periods of approximately 14 months.

AI adoption is projected to generate up to US$150 billion in annual savings in the United States by 2026, largely through efficiency gains and reduced administrative burden. These economics are accelerating deployment despite persistent regulatory uncertainty.

Constraints: Regulation, Privacy, and Trust

Adoption remains uneven across geographies, reflecting disparities in funding, digital maturity, and institutional readiness. Data privacy and compliance requirements under frameworks such as HIPAA and GDPR continue to pose significant barriers, particularly for consumer-facing chatbot services handling sensitive health information.

Major AI developers are increasingly engaging regulators, calling for clearer pathways that balance safety oversight with deployment speed as AI tools move deeper into patient-facing roles.

Outlook: Growth Outpaces Governance

The global AI-in-medicine market is projected to expand from US$13.7 billion in 2023 to US$156.8 billion by 2033, creating powerful incentives for rapid deployment. Yet regulatory frameworks remain fragmented, leaving developers, providers, and patients navigating uncertainty.

As tens of millions of users turn to AI daily for medical guidance, healthcare information access has been permanently transformed. The defining challenge for the next decade will be whether regulatory and clinical governance can evolve quickly enough to ensure this transformation delivers efficiency gains without compromising patient safety or equity.
