In early 2026, the healthcare AI sector witnessed another major milestone. OpenEvidence, a Miami-based company, secured a $250 million Series D funding round at a $12 billion valuation, cementing its position as one of the world’s most valuable and fastest-growing medical AI unicorns. In just four years, it has become the most widely adopted AI-powered clinical decision support platform among U.S. physicians, with over 757,000 verified doctor users and coverage of more than 40% of practicing physicians in the United States.
For the Greater Bay Area (GBA), OpenEvidence’s remarkable rise offers valuable insights and opportunities as we advance the “Healthy Greater Bay Area” initiative, strengthen primary care quality, and promote cross-border intelligent healthcare collaboration.
OpenEvidence’s Extraordinary Growth Trajectory
OpenEvidence’s core product is an AI-driven medical search engine that delivers reliable, traceable clinical evidence based on peer-reviewed literature. Its growth has been exceptional:
Funding Journey: Series A in February 2025 (led by Sequoia, $750 million valuation), Series B in July 2025 (led by GV and Kleiner Perkins, $3.5 billion valuation), Series C in October 2025 ($6 billion valuation), and Series D in January 2026 (led by Thrive Capital and DST Global, valuation doubled to $12 billion). Total funding raised in the past 12 months approached $700 million, backed by top-tier investors including Sequoia, Google Ventures (GV), Nvidia, Blackstone, Mayo Clinic, and others.
Adoption Scale: Over 757,000 verified physicians registered; used daily by more than 40% of U.S. practicing doctors across more than 10,000 hospitals and medical centers. Monthly clinical queries exceeded 20 million in January 2026 (up from approximately 18 million in December 2025). In 2025, over 100 million Americans received care from physicians using OpenEvidence.
Business Performance: Reached an annual revenue run rate of $100 million by early 2026, representing significant year-over-year growth.
Its business model is distinctive: the core AI medical search tool is free for verified clinicians, with revenue primarily generated through targeted pharmaceutical advertising displayed during brief answer-loading moments. This approach targets a high-value audience of approximately 600,000 U.S. prescribing physicians, achieving CPM rates far higher than typical consumer platforms, while maintaining disciplined growth rather than aggressive spending.
2026 Strategic Priorities: Evolving from Search Tool to Clinical Intelligence Layer
OpenEvidence has outlined an ambitious 2026 roadmap focused on deeper integration and broader impact:
EHR Workflow Integration: In February 2026, OpenEvidence partnered with Sutter Health to embed its platform into the Epic electronic health record system. Physicians can now perform natural language evidence searches without leaving the patient chart — a major shift from standalone app usage toward seamless clinical workflow integration. This is expected to drive enterprise seat-based licensing revenue, potentially increasing revenue per user 5–10 times compared to advertising alone.
“Visits” Clinical Documentation Tool: Launched in 2025, this ambient listening feature automatically generates medical notes from patient conversations, positioning the company in direct competition with players like Abridge and Ambience Healthcare.
Veeva Partnership — Open Vista Suite: A strategic collaboration with Veeva Systems to develop an AI product suite that connects physicians and patients to clinical trials, accelerates drug discovery, and improves adoption of approved therapies. The first products are scheduled for launch in 2026.
Workflow Expansion Beyond Search: The company is building AI agents capable of drafting clinical notes, prior authorization letters with supporting evidence, real-time drug interaction alerts, formulary and ICD-10 suggestions, and patient education materials. The long-term vision is to consolidate fragmented functions from platforms like UpToDate, Lexicomp, and others into a single AI-powered intelligent layer embedded in daily clinical workflows.
International Expansion and User Base Growth: Plans to expand beyond the U.S. starting with English-speaking markets (UK, Canada, Australia), followed by multi-language support. The company also aims to extend usage to over 5.2 million nurses, advanced practice providers, pharmacists, medical students, and others, potentially doubling or tripling its domestic user base.
A key competitive advantage lies in exclusive content licensing agreements with trusted sources such as The New England Journal of Medicine, JAMA Network, the American Medical Association, National Comprehensive Cancer Network (NCCN), PubMed, FDA, and CDC. This ensures answers are grounded in high-quality, peer-reviewed literature — a critical differentiator from general-purpose large language models.
GBAHA Perspective: Opportunities and Lessons for the Greater Bay Area
As the Greater Bay Area actively implements the national Three-Year Action Plan for Improving Medical Quality in Primary Medical and Health Institutions (2026–2028), with strong emphasis on smart construction and AI empowerment at the grassroots level, OpenEvidence’s success provides timely inspiration:
Empowering Primary Care: AI-powered clinical decision support platforms like OpenEvidence can help township health centers and community health service centers in the GBA quickly access evidence-based guidelines, improving quality in outpatient care, emergency response, rational drug use, and nursing services — directly supporting “primary care first” and medical alliance data sharing.
Cross-Border Intelligent Healthcare: Leveraging Hong Kong’s international clinical expertise, Macao’s specialty services, and Guangdong’s innovation ecosystem, the GBA can explore localized or adapted AI tools to enable cross-border electronic health record interoperability, telemedicine, and multilingual support for continuous care of Hong Kong and Macao residents in the mainland.
Innovation Ecosystem Collaboration: GBAHA encourages medical institutions, tech companies, and AI startups to jointly develop clinical decision tools tailored to local needs, including integrated Chinese-Western medicine and chronic disease management at the primary level. Learning from OpenEvidence’s EHR integration and content partnership models can accelerate the digital transformation of smart county medical communities and community health institutions.
Quality, Safety, and Sustainability: OpenEvidence’s focus on verified physicians and trusted sources aligns closely with our priorities in medical quality management, hospital infection control, and rational medication use. The Association can facilitate pilot projects that ensure AI applications are safe, explainable, and ethically sound in compliance with local regulations.
At the same time, rapid growth also brings challenges — AI accuracy and bias, sustainability of the advertising model, competition from EHR vendors like Epic, and justifying a high valuation multiple. These are important considerations for the GBA as we develop our own medical AI strategies.
Conclusion: Embracing AI to Build a Healthier Greater Bay Area
OpenEvidence’s journey from startup to $12 billion valuation in under four years demonstrates the transformative potential of AI in enhancing clinical efficiency and decision quality. The Greater Bay Area, with its strong policy support, talent pool, and cross-border integration advantages, is well-positioned to become a leading hub for medical AI innovation in Asia and beyond.
The Greater Bay Area Healthcare Association will continue monitoring global medical AI advancements, organizing forums, workshops, and pilot programs to help member institutions explore AI applications in primary care, chronic disease management, and cross-border services. Together, we can translate cutting-edge AI technologies into accessible, high-quality healthcare for every resident in the region.
Join GBAHA to stay at the forefront of how AI is empowering grassroots care, elevating quality, and fostering integration across the Greater Bay Area.
