- The Internet of Things (IoT) is a mix of the digital and physical worlds.
- It is one of the most important trends in the digital transformation of business.
- From fitness trackers to much wider scale uses like the monitoring of natural disasters, the IoT is now integrated into our society.
- In a new report, McKinsey has updated its previous analysis of the Internet of Things, including how its value could evolve over the next 10 years.
- Below are the key takeaways from this report, including the factors currently accelerating the adption of IoT and those which are holding it back.
The Internet of Things (IoT), the convergence of the digital and physical worlds, has emerged as one of the fundamental trends underlying the digital transformation of business and the economy. From the fitness trackers we wear to the smart thermostats we use in our homes to the fleet-management solutions that tell us when our packages will arrive to the sensors that promote increased energy efficiency or monitor natural disasters resulting from climate change, the IoT is now embedded in the lives of consumers and the operations of enterprises and governments.
In 2015, the McKinsey Global Institute published a research report entitled The Internet of Things: Mapping the value beyond the hype. The report analyzed the economic potential that the IoT could unleash through consideration of hundreds of use cases in the physical settings in which they could be deployed.
Six years later, in a new report, The Internet of Things: Catching up to an accelerating opportunity, we have updated the analysis to estimate how much of that value has been captured, how the potential value of the IoT could evolve in the coming decade, and the factors that explain both (see sidebar, “Defining the Internet of Things”). The market has grown considerably in the intervening years but not as fast as we expected in 2015. The IoT has faced headwinds related to change management, cost, talent, and cybersecurity, particularly in enterprises.
Here’s what our latest research found:
- The potential economic value that the IoT could unlock is large and growing. By 2030, we estimate that it could enable $5.5 trillion to $12.6 trillion in value globally, including the value captured by consumers and customers of IoT products and services.
- The IoT’s economic-value potential is concentrated in certain settings (types of physical environments where IoT is deployed). We found that the factory setting (which includes standardized production environments in manufacturing, hospitals, and other areas) will account for the largest amount of potential economic value from the IoT, around 26 percent, in 2030. The human-health setting is second, representing around 10 to 14 percent of estimated IoT economic value in 2030.
- B2B applications are where the majority of IoT value can be created, with around 65 percent of the estimated IoT value potential by 2030. But the value of B2C applications is growing quickly, spurred by faster-than-expected adoption of IoT solutions within the home.
- The 2030 IoT economic-value potential of the developed world will account for 55 percent of the global total, decreasing from 61 percent in 2020. China is becoming a global IoT force as not only a manufacturing hub and technology supplier but also an end market for value creation.
- While the potential economic value of IoT is considerable, capturing it has proved challenging, particularly in B2B settings. Many enterprises have struggled to transition from pilots to capture value at scale successfully. We estimate that the total value captured by 2020 ($1.6 trillion), while considerable, to be in the lower end of the range of the scenarios mapped out in 2015.
Our research began in 2020 before the spread of SARS-CoV-2 virus, which causes COVID-19, led to a global pandemic in the first quarter of that year. The COVID-19 crisis represents a threat to both lives and livelihoods, but it also serves as a market-shaping force. While the report on which this article is based does not focus solely on the impact of the pandemic, that impact has been acting as a catalyst for the deployment of IoT solutions in specific areas as the world grapples with managing the pandemic and enabling a faster and safer return.
Potential economic value of the IoT
The IoT stands at the forefront of our ability to bring together the digital and physical worlds in a manner that could have profound implications for both society and the economy. The benefits could be in the form of improving operations, the management of physical assets, and health and well-being, for example. Against that backdrop, the IoT can be the beating heart of digital transformations.
Setting is the main way we disaggregated the potential economic value of the IoT (Exhibit 1). Factory, the setting with the largest potential economic value in 2030, could generate around $1.4 trillion to $3.3 trillion by 2030, or 26 percent of the total.

Based on our research, the greatest potential for value creation in the factory setting will be optimizing operations in manufacturing—making the various day-to-day management of assets and people more efficient. Overall, operation-management applications in manufacturing could account for around 32 to 39 percent of the total potential IoT economic value created in the factory setting, or around $0.5 billion to $1.3 trillion, by 2030.
n the human-health setting, the second largest, IoT value involves applications that are deployed in and affect the human body. We estimate that IoT economic impact in the setting could reach around 14 percent of the total, or between $0.5 trillion and $1.8 trillion, by 2030.

Over the past five years, the perceived value of IoT solutions within healthcare has increased. From connected glucose and heart monitors for patients with chronic diseases to mass-market solutions that monitor physical activity, consumer awareness has grown significantly. IoT solutions are not only being used by individual customers but also being provided by some insurers and governments as a way to improve health and patient outcomes. The COVID-19 pandemic has potentially accelerated the use of IoT solutions in healthcare, as the world wrestles with both virus containment and a safe return to the workplace.
Another way to disaggregate potential economic value is by use-case cluster. This view allows us to observe the effects of use cases that are similar in nature but arise in different settings (Exhibit 2).
Using this approach, our research indicates that the operation-optimization and human-productivity clusters could comprise around 56 percent of IoT economic value in 2030; health and condition-based maintenance are estimated at around 15 and 12 percent, respectively.
In relative terms, autonomous vehicles (which include partial-driving automation, or level-two autonomy, and up) make up the fastest-growing IoT-value cluster. Its expected CAGR between 2020 and 2030 is 37 percent (to $0.3 trillion in 2030, from $0.01 trillion in 2020) in the high-end scenario. While autonomous-driving systems steal the headlines, the steady increase in the use of sensors throughout vehicles is set to continue as consumers demand greater safety and reliability. Indeed, during the first half of the next decade, increased safety features are expected to account for much of the IoT added value.
The safety and security use-case cluster in the vehicle setting is estimated to contribute around $130 billion to $140 billion to IoT potential value by 2030. By the end of 2020, 20 percent of vehicles globally were likely to have already been equipped with safety systems (for example, forward-collision avoidance, blind-spot assistance, and adaptive cruise control), potentially reducing the number of accidents and the value of personal auto-insurance policies.
B2B versus B2C
Our 2015 research estimated that B2B solutions would represent around 70 percent of the total value creation potential of the IoT. Five years later, B2B solutions remained the majority of the economic value from IoT solutions. But the value of B2C applications has accelerated as a result of faster-than-expected adoption of IoT solutions within the home (for example, home automation).
As a result of these dynamics, B2B applications are expected to account for 62 to 65 percent of the total IoT value in 2030. In economic terms, this translates to around $3.4 trillion in the low-end scenario and around $8.1 trillion in the high-end scenario.
While the developed world is expected to account for around 55 percent of estimated IoT economic value in 2030, the real growth story, from a geographic perspective, is China. It has become a global force in the IoT. China could be responsible for around 26 percent of the estimated economic value of IoT globally by 2030, slightly above its forecasted 20 percent share of the global economy and greater than the estimated IoT economic value from all emerging markets—19 percent of the total (Exhibit 3).
We estimate that China’s share of IoT economic value from factories could be higher than either developed or emerging markets by 2030. Today, China is estimated to have a significant share of the IoT-device installed base at around 32 percent, triple the estimated share of the emerging markets. 1
IoT tailwinds and headwinds
While the potential economic value from the IoT is large and growing, capturing this value has proved challenging. Our latest research shows that the total value captured in 2020 ($1.6 trillion) is at the lower end of the range of the scenarios we mapped out in 2015. We have updated our estimates for 2025 and beyond by adjusting for current conditions, and we have developed scenarios that account for the range of various uncertainties. In aggregate, both the low- and high-end scenarios are lower than the original 2015 estimates: around $2.8 trillion to $6.3 trillion in potential IoT economic value in 2025, compared with around $3.9 trillion to $11.1 trillion from the 2015 work.
The revisions reflect a world that has changed significantly since 2015. There have been material changes in both the trajectory of IoT adoption and realized IoT impact. In addition, scale factors, such as GDP growth and oil prices (which are exogenous to the IoT), have also shifted. In this section, we discuss the main factors influencing the future growth of the IoT market overall, though there are some variations in each setting that are detailed in the full report.
Three main factors are spurring a material acceleration in the adoption of and impact from IoT solutions today:
- Perceived value proposition. Customers see real value in deploying the IoT, a significant step forward compared with our findings in 2015. The IoT is a core enabler of the digital transformations and sustainability drives under way in companies and public institutions around the world. The $1.6 trillion in economic value generated from IoT solutions in 2020 exemplifies the technology’s ability to deliver value at scale.
- Technology. The past five years have seen remarkable advances in technology. For the vast majority of IoT use cases, affordable technology exists that enables deployment at scale. Sensors now cover the entire spectrum, from visual to acoustic and everything in between; computing is more than fast enough; storage is ubiquitous; battery power has improved. Progress in hardware has been matched by significant developments in advanced analytics, AI, and machine learning that enable faster, more granular insights and automated decision making from data provided by sensors.
- Networks. Networks act as the backbone that bring the IoT to life and make it all possible. Telecom companies’ fourth-generation (4G) networks have spread to cover more people at higher performance, and 5G networks are rapidly being deployed. Matched with improvements in other network protocols, customers have a wide range of connectivity options that can meet their requirements, be they associated with capacity, speed, latency, or reliability.
The news is not all favorable for the at-scale adoption and impact of IoT solutions. Five factors are acting to dampen both areas overall (again, with some variations across specific settings):
- Change management. Companies and governments often treat the IoT as a technology project rather than an operating-model transformation. As such, they may be led by IT without regard to required changes in governance processes, talent, and performance management. Capturing value at scale from the IoT requires the collaboration of cross-functional actors to change people’s behavior, systems, and processes, as well as introduce vigorous performance management.
- Interoperability. Ubiquitous operating systems for the IoT are still far off. Rather, the IoT landscape contains numerous proprietary, “walled garden” ecosystems. Many companies and public-sector bodies are struggling to get to scale without significant IT work to overcome the numerous system barriers.Installation. Ask consumers, enterprise customers, or governments, and many will cite installation as one of the biggest cost issues in the deployment of IoT solutions at scale. Interoperability challenges mean that almost every at-scale deployment requires customization, if not an entirely bespoke solution. The complexity of seemingly straightforward tasks, such as obtaining secure connectivity, retrofitting old devices, and linking into existing systems, adds difficulty, time, and cost, which discourages at-scale deployment.
- Cybersecurity. Consumers, enterprise customers, and governments are increasingly concerned with IoT cybersecurity, as the rising number of connected end points offer vulnerable points for hackers to exploit. Addressing this challenge requires security to be built in from the ground up, through every layer of the stack.
- Privacy. With the adoption of the California Consumer Privacy Act and the European Union’s General Data Protection Regulation, privacy is now front and center for many consumers. Companies are grappling with what customers are willing to give up in return for lower prices or special offers in a retail setting. What it takes to scale the IoT
How is the World Economic Forum ensuring that artificial intelligence is developed to benefit all stakeholders?
Artificial intelligence (AI) is impacting all aspects of society — homes, businesses, schools and even public spaces. But as the technology rapidly advances, multistakeholder collaboration is required to optimize accountability, transparency, privacy and impartiality.
The World Economic Forum's Platform for Shaping the Future of Technology Governance: Artificial Intelligence and Machine Learning is bringing together diverse perspectives to drive innovation and create trust.
- One area of work that is well-positioned to take advantage of AI is Human Resources — including hiring, retaining talent, training, benefits and employee satisfaction. The Forum has created a toolkit Human-Centred Artificial Intelligence for Human Resources to promote positive and ethical human-centred use of AI for organizations, workers and society.
- Children and young people today grow up in an increasingly digital age in which technology pervades every aspect of their lives. From robotic toys and social media to the classroom and home, AI is part of life. By developing AI standards for children, the Forum is working with a range of stakeholders to create actionable guidelines to educate, empower and protect children and youth in the age of AI.
- The potential dangers of AI could also impact wider society. To mitigate the risks, the Forum is bringing together over 100 companies, governments, civil society organizations and academic institutions in the Global AI Action Alliance to accelerate the adoption of responsible AI in the global public interest.
- AI is one of the most important technologies for business. To ensure C-suite executives understand its possibilities and risks, the Forum created the Empowering AI Leadership: AI C-Suite Toolkit, which provides practical tools to help them comprehend AI’s impact on their roles and make informed decisions on AI strategy, projects and implementations.
- Shaping the way AI is integrated into procurement processes in the public sector will help define best practice which can be applied throughout the private sector. The Forum has created a set of recommendations designed to encourage wide adoption, which will evolve with insights from a range of trials.
- The Centre for the Fourth Industrial Revolution Rwanda worked with the Ministry of Information, Communication Technology and Innovation to promote the adoption of new technologies in the country, driving innovation on data policy and AI – particularly in healthcare.

The IoT market is growing fast. The growth may be slower than expected, but it’s not for lack of confidence or belief in the impact that the technology can have. Rather, we find that operational factors are holding back the market. As we have seen, there are nuances at a setting and use-case-cluster level. This is true in not just growth but also the tailwinds and headwinds. If the IoT is to fulfill its potential, companies and their customers must address these headwinds.
