Epic controls roughly 30% of the U.S. healthcare market for electronic health records. Its dominance has created a calcified ecosystem where smaller competitors struggle to integrate, hospitals lack leverage to demand better features, and startups find it nearly impossible to build interoperable tools. The company's size has shifted it from innovator to infrastructure incumbent—a position that breeds complacency and locks in suboptimal systems across hospitals because switching costs are too high and alternatives too fragmented.
