IDC: overall IoT spending will rise 16.7% YoY to ~$800B in 2017, driven by enterprise investment, before reaching $1.4T in 2021

Context & Ripple Effects
IDC's forecast puts a number on what Intel's results were already showing: the company's Q2 2017 IoT revenue of $720M, up 26% YoY confirmed enterprise demand arriving in vendor P&Ls, not just in analyst models. The 16.7% growth to ~$800B in 2017, on a path to $1.4T by 2021, is driven by enterprise investment rather than consumer devices.
The vendor side had already begun positioning for this curve — Dell committed $1B in IoT R&D and stood up a dedicated division months after the forecast, and Microsoft followed with a $5B pledge — treating IDC's trajectory as the planning baseline.
First-order effects
- Enterprise buyers shift budget from pilot projects to production deployments, with the factory-floor use case — predictive maintenance to cut downtime — anchoring the spend.
- Hardware vendors with IoT lines, most visibly Intel, see the segment become a measurable growth engine alongside data center revenue rather than a side bet.
Second-order effects
- Rival infrastructure vendors are forced to commit comparable capital: Dell's $1B R&D division and Microsoft's $5B IoT program are direct responses to the spending curve IDC projects.
- The spend migrates down the stack toward edge computing, which IDC later sized at $240.6B through 2024 — suppliers of edge silicon and gateways capture a growing share of the same budgets.
Third-order effects
- If the pattern holds, IoT stops being a category and becomes a structural line item in enterprise IT budgets — the same dynamic Gartner later captured when it folded device spending into a $4.4T global tech-spend total for 2022.
- Competitive advantage shifts from selling connected devices to owning the platform layer — analytics, management software, and edge infrastructure — where the recurring enterprise spend concentrates.
The trend: Enterprise IoT is compounding from an $800B 2017 market toward $1.4T by 2021, with infrastructure vendors reorganizing around edge and platform layers to capture the spend.
