Open RAN enters 2026 with a credibility problem. The technology that operators and vendors have promoted as the future of radio access networking still shows a measurable distance between what its advocates promise and what networks have actually delivered, according to an assessment published by the Observer Research Foundation (ORF).

The ORF analysis, titled "Open RAN 2026: The Gap Between Promise and Practice," examines where the open radio access network movement stands as the industry moves deeper into what was supposed to be its breakthrough period. Its central finding is straightforward: the vision of fully interoperable, multivendor, software-driven RANs has not yet translated into mainstream deployment at the scale its backers projected.

That gap matters commercially. Operators in Europe, Asia and North America have spent years evaluating Open RAN as a way to reduce dependence on the three dominant network equipment makers — Ericsson, Nokia and Huawei — and to open their radio networks to a wider supplier base. The appeal sharpened after 2019, when several governments moved to restrict high-risk vendors from 5G rollouts and regulators began funding alternative RAN development. The United States, the United Kingdom, Japan and India all launched programs or policy frameworks intended to accelerate Open RAN maturity and adoption.

The ORF piece situates itself squarely in the debate over how much of that policy push has paid off. Its framing — promise versus practice — signals skepticism toward vendor marketing narratives that routinely present Open RAN as an established, ready-to-deploy architecture. In practice, operators testing or deploying the technology have repeatedly encountered the friction the analysis highlights: integration costs that erode the promised savings, performance questions relative to integrated RAN platforms, and the reality that many deployments still rely on a single prime integrator rather than a genuinely disaggregated multivendor stack.

The timing of the assessment is significant. The industry had broadly marked 2025 and 2026 as the window in which Open RAN needed to move from trials and island deployments to volume commercial rollouts if it wanted to claim a meaningful share of global RAN investment. Instead, several major operators have slowed or trimmed their Open RAN ambitions, while the largest deployments that do exist often stretch the definition of "open" — incorporating traditional vendor radios wrapped in Open RAN interfaces.

For telecom procurement teams, the analysis reads as a caution against treating Open RAN readiness as a given in network planning for 2026 and beyond. Standards work within the O-RAN Alliance continues, and interface specifications have matured considerably since the early pilot phase. But the ORF assessment suggests the binding constraints now lie less in the specifications than in the commercial and operational realities of integration, assurance and total cost of ownership.

The report lands at a moment when operators must decide whether to commit fresh capital to Open RAN or defer, and its argument implies that deferral remains rational until demonstrated deployments close the distance the analysis identifies. Whether 2026 becomes the year that gap narrows — or widens as integrated RAN vendors consolidate their 5G Advanced positions — will depend on the scale and performance of the rollouts operators actually sign in the coming quarters.
