By 2035, the IoT in manufacturing market is projected to reach a staggering $1398.8 billion, a forecast that confirms a complete re-engineering of industrial operations. This immense growth, driven by a Compound Annual Growth Rate (CAGR) of 26.2%, promises to integrate digital intelligence across every facet of production and supply chains, according to Grand View Research. Such expansion envisions factories where machines communicate autonomously, optimizing output and predicting maintenance needs.
However, this trajectory toward hyper-connectivity faces significant friction. The industrial sector, while poised for unprecedented growth through advanced manufacturing and IoT, encounters substantial barriers. High capital requirements and critical skills shortages are actively creating obstacles to widespread adoption.
While the promise of a hyper-connected, efficient industrial future is immense, its full realization will likely be uneven, favoring well-resourced and agile players, and potentially widening the gap for others.
The Proliferation of Connected Devices
- 18.5 billion — The number of connected IoT devices globally in 2024, representing a 12% growth over 2023, according to iot-analytics.
- 21.1 billion — The projected number of connected IoT devices by the end of 2025, an expected 14% year-over-year growth, iot-analytics reports.
This accelerating proliferation of connected devices creates a data-rich environment. It forms the backbone for modern industrial operations, enabling real-time monitoring and predictive analytics.
Drivers and Connectivity Standards
| Metric | 2024 Context | 2026 Context |
|---|---|---|
| Primary Adoption Driver | Global Competition | Global Competition |
| Secondary Adoption Driver | Supply-Chain Resilience | Supply-Chain Resilience |
| Tertiary Adoption Driver | Operational Efficiency | Operational Efficiency |
| Dominant IoT Connection Standard | Wi-Fi (32% of all IoT connections) | Wi-Fi (continues to dominate) |
| Significant IoT Connection Standard | Bluetooth (24% of connected IoT devices worldwide) | Bluetooth (maintains strong presence) |

Global competition and supply-chain resilience drive advanced manufacturing adoption. Pervasive connectivity standards like Wi-Fi and Bluetooth compel industries to integrate digital transformation. Manufacturers must adopt these technologies to remain competitive.
Overcoming Adoption Hurdles
Despite clear drivers, significant constraints hinder advanced manufacturing adoption. High capital requirements, skills shortages, and integration challenges actively limit the widespread implementation of these technologies, according to Nature. These non-technical barriers often prove more formidable than the technological complexity itself.
Innovation in advanced manufacturing is not an isolated internal process. Instead, it emerges through collaboration among firms, research centers, and technology providers, as Nature emphasizes. This collaborative imperative is crucial for overcoming shared constraints like substantial capital outlays and persistent skills gaps across the industrial sector.
While the benefits of advanced manufacturing are clear, overcoming financial, human capital, and technical integration barriers necessitates strategic investment and robust collaborative ecosystems. Companies failing to forge strategic alliances with research centers and technology providers will find themselves unable to overcome these high capital requirements and skills shortages, effectively ceding market share to collaborative innovators, as highlighted by Nature's findings.
Strategic Sectoral Investments
A notable surge in venture capital funding underscores strategic investment in high-stakes sectors. The value of venture capital deals in defense technology reached a record high of US$19.8 billion in the first quarter of 2026, according to Deloitte. The record high of US$19.8 billion in venture capital deals indicates a focused effort to leverage advanced manufacturing for national security and competitive advantage.
This record surge in defense tech VC funding confirms a strategic national imperative. It identifies a clear winner in this technological race: sectors where substantial funding aligns with critical strategic goals. Concentrated investment accelerates advanced manufacturing adoption, creating a distinct advantage for agile players.
Long-Term Trajectory of Industrial IoT
The number of connected IoT devices will continue its strong upward trend, confirming an ongoing industrial transformation.
- The number of connected IoT devices is estimated to reach 39 billion in 2030, reflecting a Compound Annual Growth Rate (CAGR) of 13.2% from 2025, according to iot-analytics.
This sustained growth forecast for IoT devices confirms industrial transformation is a fundamental, ongoing shift. However, pervasive integration challenges mean many deployments may remain siloed or underutilized, failing to deliver promised efficiency. The sector's pursuit of operational efficiency is undermined by its inability to address critical skills gaps and integration, suggesting a self-inflicted slowdown for many.
The industrial sector's future appears hyper-connected and efficient for those who strategically invest in technology and human capital. However, without addressing core integration and skills gaps, the promised $1.4 trillion market may remain largely untapped for many.
