IDC forecasts $800B open infrastructure market

The new number is the story

IDC has sharply lifted its 2029 forecast for annual spending on OCP-recognized IT equipment to about $800 billion, a 2.7-fold increase from the $295 billion estimate for the same year in last year’s study [1]. The revised forecast, announced by the Open Compute Project Foundation on October 13, 2026, also projects $892 billion in annual spending by 2030 across the infrastructure categories IDC measured [1].

That is not a small adjustment to a niche hardware category. It is a signal that open, standardized data-center infrastructure is becoming one of the main ways the industry expects to build AI capacity. The study covers servers, external storage, switches, IT racks, power, cooling, carrier equipment and peripherals, meaning the forecast is about the physical and networked fabric of the data center, not just a single server line or accelerator cycle [1].

The composition matters. IDC expects servers to account for roughly $814 billion of the 2030 total, with GPU-accelerated systems driving much of the growth [1]. AI-related spending is projected to reach about $628 billion in 2030, or roughly 70% of the forecast total [1]. By 2030, OCP-recognized equipment is projected to represent about 51% of spending in the infrastructure categories covered by the study [1].

Why AI makes open hardware more valuable

AI infrastructure has turned the data center into a system-level engineering problem. Training and inference clusters are not simply racks of faster servers; they are power, cooling, switching, telemetry and physical-layout problems at fleet scale. OCP’s own framing is that AI demand is pushing the industry from “chip to grid,” with infrastructure decisions spanning silicon, servers, cooling systems, power distribution and the interaction between data centers and utilities [1].

That is why the forecast is strategically important. Open hardware is not only a procurement philosophy. In this context, it becomes a way to reduce duplication, spread validation work across a broader ecosystem and give operators more than one implementation path. OCP says IDC identified the growth of solution providers and the availability of openly shared designs as adoption factors, and that use of OCP-recognized equipment extends beyond formal OCP membership to organizations implementing those designs worldwide [1].

AI Affairs, summarizing the same forecast, emphasized a useful caveat: these are annual spending figures, not cumulative investment, and the 51% share applies only to the infrastructure categories covered by the study, not to all IT spending [2]. That distinction keeps the number from being overread. The forecast is huge, but it is still a category forecast, not a promise that every vendor in the open-infrastructure chain will automatically capture revenue.

The rack is becoming the unit of competition

The most important shift is that the rack, not the individual server, is increasingly the commercial and technical unit. OCP’s October 12 ecosystem update says AI has transformed the data-center world over four years, with power densities on track to reach and surpass 1 megawatt in a single rack [3]. The same update says the OCP community has worked on paths to 1MW racks, scale-up networking, grid interaction and a standards-based chiplet ecosystem [3].

That context explains why IDC’s revision lands now. A high-density AI rack needs electrical distribution, coolant loops, physical serviceability, high-bandwidth networking and management telemetry to work together. If every operator and supplier solves those problems privately, deployment becomes slower and more expensive. If enough of the industry aligns on shared reference designs and specifications, vendors can compete on execution, integration, support and supply chain rather than reinventing every mechanical and electrical interface.

OCP says its Open Data Center for AI initiative brings together work on facility power, cooling and management, while the OCP Energy Project extends the collaboration into energy generation and storage [1]. Its AI Computing Continuum project is aimed at deployment beyond hyperscale data centers into enterprise, regional and edge environments [1]. That broader reach matters because the forecast implies open designs are no longer only for the largest cloud builders.

Vendors see a bigger prize, but also more pressure

For server, rack, thermal-management and interconnect vendors, the $800 billion 2029 figure defines a much larger addressable market. It also raises competitive pressure. Open designs can make it easier for customers to compare suppliers, and they can shift differentiation away from proprietary chassis or cabling toward system validation, deployment speed and lifecycle support.

TECHi’s analysis of the forecast used Dell as an example of this tension. It noted that Dell’s PowerRack positioning includes both conventional 19-inch and OCP-standard 21-inch configurations, alongside site assessment, engineering, validation and a single support contact [5]. In other words, the open specification may widen the market, but the supplier still has to prove that its integration work gets capacity online faster, more reliably or at lower total cost [5].

That is a central implication of the IDC revision. Open infrastructure does not eliminate vendors. It changes what customers pay them for. As designs become more standardized, the margin opportunity may move toward validated systems, delivery capacity, service quality, power-and-cooling expertise and procurement resilience. Proprietary infrastructure can still win in specific use cases, but it faces stronger pressure to justify lock-in if an open ecosystem can offer comparable performance with more supplier choice.

Recent product moves point in the same direction

The surrounding OCP Global Summit news supports the idea that the market is moving toward open rack-scale infrastructure. AMD introduced Helion on October 12 as an open blueprint for agentic AI infrastructure based on an OCP spec-design, with CPU-only and CPU/GPU configurations, liquid- and air-cooled options, and partner configurations planned for November 2026 [4]. AMD also said it plans to contribute the Helion specification to OCP for community development and adoption [4].

NVIDIA-related OCP announcements point to the same direction from another part of the accelerator ecosystem. HPCwire reported on October 13 that NVIDIA contributed Vera Rubin rack and compute-tray designs to OCP through the open NVIDIA MGX architecture, while also highlighting open work around AI factory design standards, grid resilience, Ethernet networking and a new USFP optics form factor with Cisco [6].

Taken together, these developments show why IDC’s forecast jumped. Open infrastructure is becoming a competitive layer for AI factories rather than a side project. The suppliers still compete fiercely on silicon, systems and services, but the scale of AI buildouts is forcing more common ground around racks, power, cooling and networks.

The market’s open-source armor

The phrase “OCP-recognized” is important. This is not pure open-source software, and it is not a claim that every part of an AI data center becomes interchangeable. It refers to equipment recognized around OCP designs, specifications and best practices. But the direction is clear: as AI clusters become larger, hotter and more power-dense, the industry has a stronger incentive to standardize the boring-but-critical layers that make deployment possible.

That is why the $800 billion forecast matters beyond the headline number. It suggests that open infrastructure is graduating from hyperscaler preference to mainstream market architecture. The data center is choosing its open-source armor for the AI raid: standardized racks, shared cooling approaches, open networking work and common design blocks that can be deployed across more environments.

The real test will come between now and 2030. If the market follows IDC’s path, suppliers that can combine open designs with dependable execution will have a large runway. If power availability, cooling complexity or supply-chain bottlenecks slow deployments, the forecast will be harder to reach. Either way, proprietary infrastructure now has a louder benchmark to answer: why should customers accept less interoperability if open designs can scale to the largest AI workloads?
