Abstract: In the United States today, one private company holds the digital keys to the nation’s health. Epic Systems provides the electronic health record for 42.3% of acute care hospitals and controls over half (54.9%) of all acute care hospital beds, a concentration of market power unprecedented in modern healthcare IT. This paper investigates how Epic transformed from a small, privately held vendor into the dominant force shaping the electronic health record landscape, drawing on peer-reviewed literature, federal antitrust filings, and cross-national case studies. We chart its ascent from a unified-platform niche player, to market validation through Kaiser Permanente’s multi-billion-dollar rollout, to rapid adoption under the HITECH Act. Quantitative analysis shows the U.S. hospital electronic health record market shifting from competitive to highly concentrated (Herfindahl–Hirschman Index > 2,500) after 2018, with Epic capturing nearly 70% of new hospital contracts in 2024. We examine the reinforcing mechanisms and standard practices, including network effects that add true interoperability value, high switching costs common to enterprise software, bundling practices, and workforce restrictions, that entrench this dominance, alongside alleged anti-competitive behaviors under active litigation. While some consolidation reflects legitimate business efficiencies and the inherent complexity of healthcare IT, the current level of market concentration poses significant governance challenges. International deployment failures in Norway, Denmark, Finland, and the United Kingdom reveal that Epic’s success reflects market structures rather than clear technological superiority. Regulatory contrasts highlight how the European Health Data Space’s mandatory interoperability, portability, and pre-market testing requirements are designed to prevent similar monopolization in the EU. We conclude with a reform blueprint that spans antitrust enforcement, structural separation, public utility models, and clinician-driven redesign, arguing that electronic health record systems must be governed as essential public health infrastructure. Confronting Epic’s monopoly is critical to restoring competition, fostering innovation, and ensuring that digital health serves patients and the public good.Author summary: Electronic health records (EHRs) are the digital backbone of modern healthcare. They store patient information, support clinical decisions, and enable data sharing across health systems. In the United States, however, this essential infrastructure is now dominated by a single private vendor, raising important questions about competition, interoperability, and public accountability. In this study, we examine how Epic Systems came to control a majority of U.S. hospital beds and why this level of market concentration matters. Using publicly available market data, policy analysis, legal filings, and international case studies, we show that Epic’s dominance is not simply the result of superior technology. Instead, it reflects structural forces such as federal incentive programs, weak interoperability requirements, high switching costs, and network effects that reinforce vendor lock-in. We compare the U.S. experience with large-scale EHR deployments in Europe, where different regulatory approaches have shaped market outcomes. We conclude by outlining policy options to reduce the risks of concentrating essential health data infrastructure in private hands and argue that EHR governance is a matter of public interest with direct consequences for patients, clinicians, and the future of digital health.
