Here's a number that stopped me mid-scroll: the global IoT market hit $864 billion in 2025 and is projected to reach $1.05 trillion in 2026. That's 23.1% compound annual growth. A trillion-dollar industry materializing in real time.
Now here's the number nobody's talking about: when we tested 200 IoT product recommendation prompts across ChatGPT, Claude, Gemini, and Perplexity, fewer than 12% of IoT brands in our sample appeared in any AI response.
A trillion dollars in market value. And most of the brands driving that growth are invisible to the fastest-growing discovery channel in history.
The Disconnect Between Market Growth and Discovery Evolution
The IoT industry has been laser-focused on product innovation. Smarter sensors, better connectivity, longer battery life, tighter security protocols. The engineering is genuinely impressive.
But the marketing? It's stuck in 2019.
Most IoT companies are still running the same playbook: Google Ads, trade show booths, industry publication placements, and SEO-optimized landing pages. These channels still work. But they're missing the channel that's growing fastest.
200 million people use ChatGPT every week. 40% of Gen Z now prefer asking AI over searching Google. Gartner estimates that by the end of 2026, 25% of product discovery interactions will start with an AI assistant rather than a search engine.
The consumer discovery path is shifting under the IoT industry's feet. And most brands haven't noticed.
The AI Visibility Gap by IoT Vertical
We broke down our analysis across the major IoT segments. The visibility gap looks different depending on the vertical, but it exists everywhere.
Consumer Smart Home (Market share: ~25%)
This is the most visible IoT vertical in AI responses, but concentration is extreme. In smart home product queries, the top 3 brands per category capture 80-95% of all AI mentions. Ring, Nest, Ecobee, Arlo, iRobot—these names dominate across engines.
The gap: Hundreds of smart home startups and mid-market brands with competitive products that AI never recommends. A smart lock startup with 8,000 five-star reviews on Amazon won't get mentioned if Wirecutter hasn't reviewed it and it doesn't have a Wikipedia entry.
Industrial IoT (Market share: 64.36%)
Enterprise IoT represents nearly two-thirds of the total market. Companies like Siemens, Honeywell, Rockwell Automation, and ABB dominate AI responses for industrial IoT queries.
The gap: Mid-market industrial IoT platforms and specialized sensor manufacturers are almost completely invisible. When we asked AI engines "best predictive maintenance IoT platform for manufacturing," the responses consistently featured the largest enterprise vendors. Specialized platforms with better fit for specific use cases—say, vibration monitoring for wind turbines—rarely appeared.
This matters because industrial IoT purchasing increasingly starts with research, and that research increasingly involves AI assistants. A procurement engineer asking Claude about sensor options for a specific application gets the same big-name answers regardless of whether those vendors are actually the best fit.
Healthcare IoT (Market share: ~8%)
Healthcare IoT is projected to hit $289 billion by 2028. Remote patient monitoring, connected medical devices, hospital asset tracking—the applications are expanding rapidly.
The gap: AI responses for healthcare IoT queries are dominated by a handful of names: Medtronic, Philips, GE Healthcare, Abbott. Specialized companies making innovative remote monitoring devices or hospital logistics platforms are largely absent from AI recommendations.
The stakes here are particularly high because healthcare purchasing decisions have long evaluation cycles. If a hospital system's initial AI-assisted research doesn't surface your brand, you may never enter the consideration set.
Automotive IoT (Market share: ~10%)
Connected vehicles, fleet management, V2X communication—automotive IoT is a fast-growing segment with heavy investment from both traditional automakers and tech companies.
The gap: Tesla, BMW, and Mercedes dominate AI conversations about connected vehicles. Fleet management queries surface Samsara, Geotab, and Verizon Connect. Dozens of innovative automotive IoT companies—telematics startups, aftermarket connected car platforms, EV charging network providers—get minimal or zero AI mentions.
Wearables and Personal IoT (Market share: ~7%)
Apple Watch, Fitbit, Garmin, Oura—the same concentration pattern repeats. AI recommendations for wearables are dominated by 4-5 brands despite a market with hundreds of players.
The gap: Niche wearable makers focused on specific health metrics, sports performance, or accessibility get buried. A company making the best glucose monitoring wearable for diabetics might lose to "Apple Watch can track your blood sugar" in AI recommendations, even if the specialized product is far more capable.
Why IoT Brands Are Particularly Vulnerable
The IoT visibility gap isn't just a general AI search problem. Several characteristics of IoT products make them especially vulnerable.
1. Technical Complexity Creates Positioning Challenges
IoT products are inherently technical. Many brands lead with specifications—protocols, connectivity standards, data rates, sensor accuracy. This information is critical for engineers but terrible for AI discoverability.
When a consumer asks "what's the best smart home security system," AI doesn't want to explain Zigbee vs. Z-Wave vs. Thread protocols. It wants to name a brand that works. The brands that translate technical capabilities into clear consumer benefits win the AI recommendation.
2. Fragmented Ecosystems Confuse AI Models
The IoT ecosystem fragmentation problem—dozens of protocols, competing standards, varying compatibility—makes it hard for AI to make clean recommendations. When a product works with "some Alexa devices but not all" or "requires a specific hub for full functionality," AI tends to default to brands with simpler, more universal compatibility stories.
Matter protocol adoption is helping standardize this, but we're still in the transition period. Brands that clearly articulate Matter support and broad ecosystem compatibility get a recommendation boost.
3. B2B IoT Has Minimal Consumer-Facing Content
Industrial and enterprise IoT companies often have websites designed for a technical audience. White papers behind lead forms. Dense specification sheets. Minimal plain-language content explaining what the product does and why it matters.
AI models struggle with gated content—they can't read your white paper if it's behind a form. And technical documentation without clear positioning statements gives AI nothing to recommend you for.
4. Rapid Innovation Outpaces Information Ecosystems
IoT product cycles are fast. A sensor company might release three new product lines in a year. But the information ecosystem—reviews, comparison articles, Wikipedia entries, forum discussions—moves slower. By the time a product gets reviewed on major tech sites, there's already a newer version.
This creates a persistent lag between product reality and AI knowledge.
The Economic Impact of Invisibility
Let's put some rough numbers on this.
If the IoT market is $1.05 trillion and even 10% of purchasing decisions are influenced by AI-assisted research (a conservative estimate given the 40% Gen Z preference data), that's $105 billion in purchasing decisions where AI visibility matters.
If your brand is invisible in those AI conversations, you're not competing for your share of that $105 billion. Your competitors—the ones AI does recommend—are capturing demand you never even knew existed.
The compound effect is what makes this truly alarming. AI recommendations drive brand awareness, which drives more mentions, which drives more AI recommendations. The visible get more visible. The invisible stay invisible.
What the Smart IoT Brands Are Doing Differently
We've been tracking a few IoT brands that have significantly improved their AI visibility over the past six months. The patterns are consistent.
They simplified their positioning.
One industrial IoT company went from "end-to-end cloud-native IoT platform for enterprise digital transformation" to "predictive maintenance for factory equipment." Their AI mention rate tripled in three months.
They invested in third-party coverage.
Not just press releases—actual product reviews, comparison features, and expert recommendations in publications that AI models treat as authoritative. One smart home brand specifically targeted Wirecutter, CNET, and Tom's Guide with review samples and saw measurable improvement in AI recommendations within one model update cycle.
They documented everything publicly.
API docs, integration guides, compatibility matrices—all publicly accessible, well-structured, and written in clear language. AI models can parse this content and use it to make informed recommendations.
They started monitoring their AI visibility.
You can't improve what you don't measure. Tools like GeoBuddy (geobuddy.co/check offers a free check across all four major AI engines) let IoT brands track their visibility score, sentiment, competitor positioning, and citation sources over time. The brands seeing improvement are the ones tracking it weekly.
They embraced the llms.txt standard.
The forward-thinking IoT brands we're tracking have implemented llms.txt files—a structured text file at their website root that provides AI crawlers with a concise, parseable summary of their products, capabilities, and integration options. For IoT companies with complex product lines and compatibility matrices, this is particularly valuable. It gives AI models a clean reference point instead of forcing them to piece together information from scattered product pages and spec sheets.
The Vertical Opportunity Map
Not every IoT vertical faces the same level of AI visibility competition. Understanding where the gaps are widest reveals where the opportunity is greatest.
Low competition, high opportunity: Agricultural IoT
Smart farming and precision agriculture represent a $22 billion market growing at 11.4% annually. AI queries about agricultural sensors, crop monitoring, and smart irrigation systems return surprisingly thin results. Most responses default to generic advice rather than specific brand recommendations. An agricultural IoT brand that invests in AI visibility now could own this space with relatively little competition.
Medium competition, evolving fast: Smart building and energy management
Commercial building automation and energy IoT is a massive market where brands like Schneider Electric and Johnson Controls dominate AI responses. But the growing demand for smart energy management in residential and small commercial settings has created a gap. Brands serving this mid-market—smart EV chargers, home energy monitors, solar management systems—have room to establish AI presence before the space gets crowded.
High competition, still winnable for specialists: Consumer health wearables
Apple, Fitbit, and Garmin dominate general wearable queries. But specialized health devices—CGMs, blood pressure monitors, sleep tracking devices, hearing aids with IoT features—represent niches where the dominant consumer brands don't have the best products. A company making the best connected blood pressure monitor could own that specific AI query space if they build the right signals.
Emerging, almost no competition: Smart city infrastructure
Cities are deploying IoT at scale—smart streetlights, traffic sensors, air quality monitors, waste management systems. AI queries in this space return mostly generic information rather than brand recommendations. The first smart city IoT vendors to invest in GEO will have a wide-open field.
Where This Is Headed
The IoT market isn't slowing down. $1.05 trillion in 2026 is just the beginning—projections put it at $1.5 trillion by 2028 and over $2 trillion by 2030.
Meanwhile, AI-assisted product discovery is accelerating even faster. Every major tech company is integrating AI into their search and shopping experiences. Google's AI Overviews, Apple's Siri improvements, Amazon's AI shopping assistant—all of these are narrowing the funnel of brand discovery.
There's another trend worth watching: AI agents that make purchasing decisions autonomously. We're not fully there yet, but the trajectory is clear. Companies like OpenAI and Google are building AI systems that can browse the web, compare products, and eventually execute purchases on behalf of users. When an AI agent is choosing an IoT sensor for a smart building project, it won't browse trade show exhibitor lists. It'll query its knowledge base, compare options based on available information, and select the product with the strongest signal.
This is the future of IoT procurement. And the brands that are visible to AI today are building the foundation for that future.
The IoT brands that will thrive in this environment are the ones that recognize a fundamental truth: building a great product is necessary but no longer sufficient. You also need to be discoverable in the channels where your buyers are increasingly making decisions.
A trillion-dollar market deserves better than invisibility. The brands that figure out AI visibility now—while their competitors are still pouring everything into trade shows and Google Ads—will have a structural advantage that compounds for years.
The question isn't whether AI will reshape IoT product discovery. It already is. The question is whether your brand will be part of the conversation.
