Epic Widens the Lead, Oracle Health Bleeds Hospitals: KLAS 2026

What happened

KLAS Research published its 2026 US Acute Care EHR Market Share report and the headline is a widening chasm at the top. Epic expanded its acute care footprint by 77 hospitals in 2025 while Oracle Health lost 56, marking a third consecutive year of contraction for the former Cerner franchise. The report also flags a persistent satisfaction gap, with Oracle Millennium scoring at the bottom of every hospital size band that KLAS tracks.

Why it matters for hospital/HealthTech buyers

EHR gravity determines almost every downstream tech decision inside a hospital. Interface budgets, analytics roadmaps, ambient scribing pilots, revenue cycle vendors, patient portal RFPs, and even physician recruiting pitches all bend around the core system of record. Three years of net customer losses at Oracle Health signal a market that is repricing risk in real time. CIOs at Millennium sites are being asked, in board meetings and physician town halls, why they are staying, and vendors with Epic-first roadmaps are quietly reprioritizing Oracle integrations further down the backlog.

The secondary effect is talent. Every hospital that migrates off Millennium drops trained analysts and clinical informaticists back into the labor pool, which reshapes staffing costs and consulting rates for whoever is still on the platform.

Our take

Market share is a lagging indicator. Satisfaction is not. When the same vendor lands at the bottom of every cohort for three years running, procurement teams start planning migrations even before contracts come up for renewal, because they know the internal political fight takes eighteen months on its own. Oracle can still stabilize this by delivering something genuinely differentiated on the AI and cloud side of the house, but the window for narrative repair is closing. If the 2027 report shows a fourth year of losses, "Oracle Health" starts getting talked about the way "athenahealth acute care" was talked about a decade ago: a viable business, just not the one anyone builds their five-year plan around. Buyers evaluating adjacent HealthTech should be asking every vendor a blunt question right now: what is your Millennium sunset plan, and how does it change your pricing for us?
