Gartner does not publish a Market Guide for Health Information Exchange in the public record, and none has surfaced under that name. The firm's coverage of the market lives inside its Enterprise Electronic Health Records quadrant, where the HIE capability shows up as a vendor differentiator: InterSystems, a Leader in the July 2026 edition, is cited for deep interoperability and its work in regional and national health information exchanges. The exchange market is real. Its analyst coverage is borrowed from the neighboring category.
The market the name describes
Health information exchange is healthcare's plumbing: the movement of clinical data between the systems that hold it, the hospital, the clinic, the lab, the payer, so that the patient's record follows the patient rather than the institution.
The market's value is measured in the highest-value message types: the admission, discharge, and transfer notifications that tell a care team when a patient lands somewhere else, the lab result that arrives before the follow-up visit, the longitudinal record assembled from a dozen systems.
The exchange is the plumbing, and plumbing has no glamorous scorecard, which is why the market exists in the world but barely exists in the analyst's catalog.
The coverage that exists: the EHR quadrant and the HIE capability inside it
The working map for this market is Gartner's Magic Quadrant for Enterprise Electronic Health Records, published July 6, 2026, by Veronica Walk and Jonathan Rivera.
InterSystems holds a Leader placement there, and its positioning runs on exactly the HIE capability: deep interoperability and its work in regional and national health information exchanges, with the HealthShare platform as the exchange layer alongside its IntelliCare EHR and TrakCare platform used by more than 600 hospitals globally.
The placement is the market's quiet signal. Interoperability is the EHR's virtue and the HIE's entire product, and Gartner scores the two together because the buyers buy them together. The exchange market's analyst recognition is a feature inside a neighboring quadrant.
The vendor field's three shapes
The industry's HIE field, from the market's own surveys and selection guides, not from Gartner, falls into three shapes.
The EHR-embedded exchanges: Epic's Care Everywhere, the interoperability that rides inside the dominant hospital system. The integration engines: NextGen's Mirth Connect, Lyniate's Rhapsody, Infor Cloverleaf, the middleware that moves HL7 and FHIR traffic between legacy systems. And the national networks: the TEFCA-aligned hubs, Carequality, CommonWell, eHealth Exchange, the networks of networks that make one connection reach most of the country.
The three shapes serve three buyers: the hospital that wants exchange as an EHR feature, the integration team that needs an engine, and the organization that wants national reach without a hundred point-to-point contracts.
The network-of-networks structure
The market's structural answer to its own fragmentation is the network of networks: the qualified health information networks that interconnect, so a single connection reaches the national fabric.
The economics are the adoption story. A clinic connecting once to a national network gains access to the exchanges its patients' data flows through, and the high-value use cases, the ADT notifications, the cross-network record lookup, become feasible without the historic integration cost.
An ADT notification is the highest-value message in healthcare, and the network-of-networks structure is what finally made it affordable at scale.
The honest state of the record
The honest limit is the absence itself. No Gartner Market Guide exists for this market in the public record, no representative vendor list carries the Gartner brand, and the buyer assembles the map from the EHR quadrant's interoperability citations, the industry's own surveys, and the vendor demos.
The absence is not an accident of timing; it is a statement about the market's structure. The HIE function has been absorbed, into the EHRs, into the integration platforms, into the national networks, and what remains as a standalone market is thinner than the name implies. The coverage is borrowed from the neighboring category because the market itself borrowed the capability.
Four questions for the interoperability buyer
Which shape does the institution actually need? EHR-embedded, integration engine, or national network. The three shapes serve three problems, and the wrong shape is the most expensive mistake in this market.
What does the network connection actually reach? The network-of-networks promise is coverage. Ask for the specific exchanges, the geographic reach, and the ADT notification flow demonstrated on the buyer's own patient population.
Is the exchange built on open standards? HL7, FHIR, and the TEFCA participation rules are the exit ramps. Ask which standards are native and which are proprietary bridges, because the proprietary bridge is the lock-in.
Who runs the exchange when the vendor is not around? The exchange is operational infrastructure with clinical consequences. Ask for the incident history, the downtime record, and the escalation path, because a failed exchange is a failed handoff.

Gartner Research
This article draws on Gartner's coverage of health information exchange. No Market Guide or Magic Quadrant exists under the name Health Information Exchange in the public record, and none has surfaced under that name. The anchor material is Gartner's Magic Quadrant for Enterprise Electronic Health Records, published July 6, 2026, by Veronica Walk and Jonathan Rivera, in which InterSystems is a confirmed Leader cited for deep interoperability and its regional and national health information exchange work. The wider vendor field and the network-of-networks structure described here come from industry market surveys and selection guides, not from Gartner.

The same shift shows up next door, in Healthcare Provider Industry Cloud Platforms. Innovaccer swept both axes of Gartner's brand-new quadrant for this category, backed by a specific number: a 27 percent quality-gap improvement worth roughly 15 million dollars a year at one health system alone.
The neighboring coverage here is Customer Experience Platforms For Healthcare. Consumer comfort with a general AI chatbot and with their own health insurer's AI tool differ by two percentage points. That indifference is the strategic problem this category exists to address.
