Investing in Internet of Things Stocks

Computers and smartphones aren't the only devices connecting to the internet. Everyday objects such as lights, televisions, major appliances, cars, and even doorbells are being brought online. The Internet of Things (IoT) refers to the networks of devices and objects that communicate with other devices in the same network via connections to data centers.

What is IoT?

What is the Internet of Things?

Although there is plenty of overlap among general technology, cloud computing, and the IoT, pure-play IoT companies are relatively rare. Any company that makes consumer electronics devices or sensors or chips for industrial or commercial purposes has at least some exposure to IoT technology. Software platforms that manage IoT devices and cloud computing companies are also engaged with the IoT sector.

Best IoT stocks

These five top IoT stocks range from a diversified tech giant to a pure-play IoT company:

1. Cisco Systems

Cisco Systems is the leading provider of enterprise networking hardware. Because its products form the backbone of the internet, the tech giant benefits from the explosion of internet-enabled devices.

Cisco sells networking hardware designed for handling large numbers of connected devices, including rugged, durable products aimed at industrial applications. On the software side, the company provides the Cisco Edge Intelligence platform and other tools for managing IoT data and devices.

Cisco is also one of the largest cybersecurity companies. The company offers hardware, software, and services aimed at securing networks against threats, including those specifically targeting IoT systems.

Cisco is a low-risk way of investing in IoT. The company is supremely profitable, having generated net income of $5.1 billion on revenue of $27.8 billion through the first six months of fiscal 2025. And it's not only on the income statement that Cisco shines. Through the first half of fiscal 2025, Cisco generated $5.5 billion in free cash flow.

The company is sensitive to global economic conditions, given that its customer base includes many large companies, organizations, and governments. However, investing in the stock is a good way to gain exposure to IoT without taking big risks.

This sensitivity to economic conditions played out during the COVID-19 pandemic, with the company experiencing a pause in demand from some customers as they grappled with economic uncertainty. Similarly, the implementation of tariffs may affect the company's profitability. In February 2025, management acknowledged that it was taking steps to mitigate the effects of proposed tariffs on Canada, China, and Mexico.

While there may be uncertainty with regard to tariffs, Cisco remains as dominant as ever, and the company is poised to benefit from the growth of the IoT market.

2. Alarm.com

While Cisco's market cap borders $228 billion, cloud software provider Alarm.com is valued at just a few billion. Its relatively small size makes it riskier than the tech giant, but the company has plenty of growth potential.

Alarm.com provides a cloud-based software platform for managing a connected home or business. Subscribers use the software to manage internet-enabled devices, including security cameras, lights, locks, thermostats, and a range of other supported products.

Alarm.com partners with service providers to sell its platform to consumers and businesses. The company currently works with about 12,000 service providers in more than 70 countries, and its products are found in about 67 million properties worldwide. Management recognizes ample growth opportunities, identifying more than 500 million serviceable properties.

Recognizing both steady top- and bottom-line growth from 2016 through 2023, Alarm.com has increased revenue at a 17.4% compound annual growth rate (CAGR) and adjusted earnings before interest, depreciation, and amortization (EBITDA) at a 17.3% CAGR.

Alarm.com's total long-term market opportunity, split evenly between the smart home and commercial markets, is $58 billion. Since only a small fraction of homes are currently using Alarm.com’s platform, the IoT company has a long growth runway.

With the smart home trend here to stay, Alarm.com -- and its millions of subscribers -- is an early leader.

3. DexCom

The Internet of Things goes far beyond consumer devices. DexCom is focused on medical devices used to continuously monitor glucose for diabetics. The company's G7 system delivers real-time data to smartphones and smartwatches without the need for finger sticks.

The number of people in the U.S. with diagnosed diabetes grew from 1.58 million in 1958 to 23.35 million in 2015, according to data from the Centers for Disease Control and Prevention. Today, about 38 million Americans have diabetes, and approximately 98 million American adults have prediabetes.

The combination of growing rates of diabetes and the transition to continuous glucose monitoring will give DexCom plenty of growth opportunities in the coming years. In 2024, revenue grew 11% year over year to $4 billion. Management projects continued growth in the coming year, forecasting 2025 sales of $4.6 billion.

DexCom has historically traded at expensive multiples, but for those willing to take on some risk to gain exposure to both IoT and healthcare, it's a stock to consider.

4. Impinj

Impinj specializes in solutions involving radio-frequency identification, or RFID. Impinj's RFID tags are used by retailers, manufacturers, and logistics companies to track inventory and assets.

The market for RFID products, including tags, readers, software, and services, was worth $15 billion in 2023, according to Global Market Insights, and it's expected to grow at a CAGR of more than 12% from 2024 to 2032. Apparel retail is so far one of the biggest markets by volume for RFID technology, but the technology also has applications in supply chain logistics.

Impinj had a rough go of it during the COVID-19 pandemic, partly due to retail store closures, but the company has bounced back in a big way. Sales soared from $190.3 million in 2021 to $307.5 million in 2023. More recently, revenue in the second quarter of 2024 soared 19% year over year to $102.5 million, and the company generated more than $40 million in free cash flow.

Impinj estimates that just 0.3% of connectable items are connected today. In the long run, trillions of consumable objects, ranging from food packaging to tires, could be tracked using RFID technology. Each RFID endpoint costs only pennies, making the technology economical for a wide array of uses.

Impinjg has shipped more than 100 billion RFID endpoints over its lifetime, and the number could rise substantially in the coming years. Impinj is far from a sure thing as an investment, but it's a company to watch in the IoT space.

5. Intel

IoT isn't Intel's core market, but the semiconductor giant's data center chips power the cloud data centers that link IoT devices. Despite rising competition, Intel still dominates the data center CPU market.

Beyond powerful chips crunching data in the cloud, Intel sells chips meant for the edge. Its Xeon D family of processors, for example, has built-in AI for IoT applications and can operate in harsh, rugged conditions.

In 2015, Intel acquired Altera to expand its exposure to the IoT. Recently, Intel said it is exploring the spinning off of Altera and potentially holding an initial public offering (IPO) for it in the near future.

Intel also owns a majority stake in Mobileye (MBLY -4.32%), a leading developer of autonomous driving and advanced driver assistance systems. There are more than 1 billion cars on the road globally, and the fleet will become smarter and more connected.

In addition to selling its own chips that serve various parts of the IoT market, Intel is pouring tens of billions of dollars into building out its manufacturing capacity and starting up its own foundry business. Intel can further tap into the growing demand for IoT devices by manufacturing the necessary chips for other companies.

Intel isn't a pure-play IoT stock, but the company has multiple ways to benefit from a growing IoT industry.
