The contest is not simply over which instruction set is better: customers weigh software and tools, licensing economics, customization, and the needs of each workload. Arm’s 2026 filing names RISC-V as a competitive risk; the evidence available here does not show that it has already broadly displaced Arm.
Why RISC-V is a real competitive threat
Arm’s own risk disclosure makes clear that it takes the challenge seriously. In its 2026 Form 20-F, Arm says, “We face intense competition and could lose market share to our competitors.” It specifically describes RISC-V as an open-source alternative and warns that growing technical development and market support could lead customers to choose it instead. The filing also notes that some Arm customers support RISC-V.
That is meaningful evidence of a competitive risk, not proof of how much share Arm will lose. A company risk filing reflects Arm’s own assessment, rather than an independent forecast. It does, however, show why the question matters: customers may have alternatives, and some are investing in them.
What the competition is really about
An instruction set architecture (ISA) defines the instructions a processor can execute. But choosing an ISA is also a platform decision. A chip must be supported by compilers, operating systems, debugging and verification tools, developers, and a durable software-maintenance path. The value of an open standard or a mature ecosystem depends on the particular customer and product.
#1 Best Overall
- Software and tools: Consider whether the necessary operating systems, applications, compilers, debug tools, and long-term support are ready for the intended product.
- Economics and control: Licensing and royalty arrangements matter, but so do the cost of internal engineering, customization freedom, and reliance on outside IP providers.
- Workload fit: Performance, power use, chip area, integration, and accelerator requirements vary by application. The sources cited here do not provide matched Arm-versus-RISC-V benchmarks, so they cannot establish a universal performance winner.
- Standards and compatibility: Ratified extensions, application-processor profiles, interoperability, and supported platform baselines affect whether implementations work together reliably.
- Evidence of adoption: Membership, specifications, and announced design intent are not the same as completed silicon, shipping products, working software, and sustained deployment.
Arm points to investment in software and tools, customer resources, and competitive cooperation as important factors in this landscape. RISC-V’s open-standard model can appeal to organizations seeking more control or workload-specific designs, but openness alone does not provide a complete, supported platform.
Where the balance may differ
A single winner-takes-all prediction obscures the differences among markets. The relative value of customization, an established software base, platform support, and integration varies by application.

| Market | What to examine |
|---|---|
| Embedded systems | Whether a focused design benefits from customization, and whether its software, tools, and ongoing support are sufficient. |
| Automotive | Platform standards, interoperability, verification, long-term support, and evidence of actual deployments. |
| Client devices | Application and operating-system compatibility, developer support, power and performance for the target product, and availability of a coherent platform. |
| Data centers | Software readiness, workload-specific performance and power, integration needs, and demonstrated deployments. |
| AI and edge AI | How well the processor platform integrates with the required accelerators and software for the specific workload. |
RISC-V International’s 2025 annual report highlights automotive, data center, edge AI, security, and space, alongside standards and software-enablement milestones. That is useful evidence of activity and priorities, as reported by the standards organization itself; it should not be treated as independent proof of market displacement.
How to read the RISC-V growth projection
In the report’s CEO foreword, RISC-V International CEO Andrea Gallo says, “One trend speaks loudest: RISC-V has become a highly valued architecture for both specific workloads and industry verticals.” He also attributes to SHD Group a projection that RISC-V market penetration will rise from 2.5% in 2021 to 33.7% by 2031. This is a forecast cited in a report published in 2026, not a measurement of current share or a tally of Arm’s losses. The cited material does not establish the projection’s methodology or define a comparable segment-by-segment measure.
What would show that Arm is holding its ground—or losing it
To judge the competition, look for evidence at the level of products and workloads rather than treating standards progress or forecasts as outcomes. Useful evidence includes shipping silicon, software support, sustained deployments, and independent, comparable performance data. Arm’s 2026 annual report is another company filing, not an independent market-share dataset.
The sources cited here do not establish independent, like-for-like Arm-versus-RISC-V performance benchmarks or market-share series by segment. They therefore support a qualitative judgment, not a precise timetable or numerical forecast for displacement: Arm faces a real challenge, while the scale of that challenge will depend on execution and the requirements of each market.
