Top 10 IoT Companies in 2026

Amazon Web Services is the dominant IoT cloud platform — managing several billion connected IoT devices and operating a marketplace with nearly 3,000 IoT offerings as of September 2025 per IoT Analytics research. AWS’ IoT strategy is not one product but an ecosystem: AWS IoT Core (managed cloud connectivity for billions of devices), AWS IoT Greengrass (edge computing runtime for local processing), AWS IoT SiteWise (industrial asset data management), AWS IoT Events (automated detection and response), AWS IoT Device Defender (security monitoring), and AWS IoT Device Management (fleet management at scale). Its approximately 18% IoT market share reflects the default choice status that AWS holds in enterprise IoT architecture decisions — enterprises building new IoT deployments default to AWS IoT Core first unless they have specific requirements that pull them elsewhere.

AWS IoT’s Marketplace ecosystem — featuring nearly 1,500 IoT-specific offerings across analytics, device management, connectivity, and industrial IoT — represents the richest third-party IoT solution ecosystem available on any single cloud platform. Volkswagen Group’s use of AWS IoT to increase plant efficiency, uptime, and vehicle quality is a reference deployment that validates AWS IoT’s industrial applicability at one of the world’s most demanding manufacturing environments. AWS Greengrass V2 extends AWS cloud capabilities to edge devices — running Lambda functions, Docker containers, and ML inference locally on IoT gateways and devices without cloud connectivity for latency-sensitive applications.

Microsoft Azure IoT is the enterprise IoT platform that most large organizations evaluating cloud-first IoT architecture place on their shortlist alongside AWS — driven by Microsoft’s enterprise relationships, Azure’s deep integration with existing enterprise data and application infrastructure, and Azure Digital Twins’ unique capability for modeling complex physical environments. Azure IoT Hub connects and manages IoT devices at scale with per-device authentication, built-in device management, and scaled provisioning. Azure IoT Operations (the newest addition, reflecting Azure’s 2025 evolution of its industrial IoT approach) enables capturing asset data at the edge and processing it with Azure Arc–enabled services. IoT Analytics reported that AWS and Microsoft together showcase nearly 3,000 IoT offerings combined on their B2B marketplaces as of September 2025.

Azure Digital Twins is Microsoft’s most distinctive IoT capability — enabling creation of comprehensive digital models of physical environments, assets, and processes. Where AWS IoT SiteWise manages asset data, Azure Digital Twins creates a live, queryable model of the entire physical environment — understanding that “Motor 7B is connected to Production Line 3 which feeds Warehouse A which ships to Distribution Center West” — enabling spatial queries and simulation that flat device data cannot support. In October 2025, AT&T and Ericsson launched the AT&T IoT Marketplace on Microsoft Azure, integrating Ericsson’s Digital Experience Platform for IoT service management across transportation and healthcare. Microsoft Defender for IoT provides OT/IT security for industrial environments directly within the Azure security stack.

Siemens is Europe’s largest industrial manufacturing company and the world’s leading industrial IoT platform vendor for the manufacturing and smart infrastructure sectors — with €77 billion+ in total FY2025 revenue and approximately 418,000 employees globally. Siemens Xcelerator is its open digital business platform — a curated portfolio of IoT-enabled hardware, software, and services that spans industrial automation, digital twins, smart buildings, and energy management. Insights Hub (previously MindSphere, rebranded in 2023) focuses specifically on manufacturing excellence — collecting real-time machine and asset data from factories, enabling process optimization, digital twin simulation, and industrial automation for continuous improvement programs. In 2026, Insights Hub was enhanced with AI-powered predictive maintenance modules that allow manufacturers to simulate production scenarios in digital twins before implementing physical changes.

Siemens’ competitive advantage in IoT is its vertical depth: unlike hyperscalers that provide horizontal infrastructure, Siemens understands the specific protocols (OPC UA, PROFINET, PROFIBUS), equipment behaviors, and safety requirements of manufacturing, energy, and building environments at the operational technology level. This OT depth — accumulated over 175 years of industrial engineering — cannot be replicated by cloud platforms through API integrations. Siemens’ IoT solutions for smart buildings improve operational efficiency while enhancing occupant wellbeing and optimizing space and asset utilization. Audi’s use of Siemens solutions to transform operations with sensors, smart devices, and smart processes demonstrates the scale at which Siemens IoT is deployed in demanding automotive environments.

Cisco is the IoT company that provides the network infrastructure layer that every IoT deployment depends on — the rugged switches, gateways, wireless access points, and network management platforms that connect IoT devices to the enterprise network and cloud — but its IoT strategy in 2026 extends well beyond passive connectivity into active OT security, edge intelligence, and industrial observability. Cisco’s IoT portfolio serves industrial, infrastructure, and transport sectors with end-to-end architecture: rugged IE Series industrial Ethernet switches that survive factory floor environments, IoT Operations Dashboard for centralized device management, Cisco Edge Intelligence for securely routing data from connected assets to multi-cloud destinations, and Cisco Cyber Vision for full visibility into Industrial Control Systems (ICS).

Cisco Cyber Vision is the most commercially significant IoT product in Cisco’s portfolio in 2026 — providing complete visibility into OT environments where IT security tools cannot see because industrial protocols (Modbus, EtherNet/IP, PROFINET) are invisible to standard network security tools. As OT environments connect to enterprise IT networks (the IT/OT convergence that every Industry 4.0 program requires), the security blind spots in industrial control systems become enterprise-level vulnerabilities. Cyber Vision illuminates those blind spots by passively monitoring industrial network traffic and identifying every device, every protocol, and every anomalous communication pattern in the OT environment. Audi’s documented use of Cisco solutions to transform operations with new sensors, smart devices, and smart processes confirms Cisco IoT’s scale in demanding industrial environments.

• End-to-end IoT architecture: rugged switches + gateways + software + security
• IE Series: ruggedized industrial Ethernet for factory, utilities, transport environments

Qualcomm is the IoT company that powers hundreds of millions of connected devices without being visible to the enterprises deploying them — its Snapdragon and QCS-series processors, 5G modems, Wi-Fi chips, and AI accelerators are embedded in industrial gateways, smart cameras, edge computing devices, and connected machinery across every IoT vertical. Every industrial gateway processing factory floor data, every smart camera analyzing production quality, every connected vehicle transmitting telematics, and every smart building controller managing HVAC systems likely runs on Qualcomm silicon. Its approximately $5 billion+ in annual IoT revenue (estimated) reflects the depth of its device ecosystem penetration that no single enterprise deployer directly sees but every IoT deployment depends on.

Qualcomm’s IoT strategy in 2026 centers on the Qualcomm Aware platform — which addresses the industry’s fragmentation problem by integrating hardware, connectivity, and services into a user-friendly platform that enables enterprises to achieve real-time asset visibility and data-driven insights without assembling heterogeneous components from multiple vendors. Its Vision Intelligence Platform supports computer vision, smart cameras, and autonomous drones — the fastest-growing IoT application categories. The QCS-series processors combine 5G, Wi-Fi, and AI accelerators specifically optimized for IoT edge applications — providing the compute density for running ML inference locally on edge devices that traditional IoT microcontrollers cannot support. As IoT applications move from simple telemetry to AI-powered edge intelligence, Qualcomm’s semiconductor leadership converts directly into IoT platform positioning.

• ~$5B+ IoT revenue (estimated); hundreds of millions of IoT devices running Qualcomm silicon
• Qualcomm Aware: integrated hardware + connectivity + services IoT platform

Samsara is the fastest-growing IoT company at scale — and the only pure-play connected operations platform that has achieved hyperscale-relevant commercial metrics. Its $1.64 billion ARR as of Q2 FY2026 (July 2025), growing at 30% year-over-year from the SEC-confirmed filing, serves tens of thousands of customers in fleet management, field operations, and industrial monitoring. Samsara’s stock ticker (NYSE: IOT) is itself a statement of category ownership. Its commercial achievement — building a $1.6B+ ARR business on the premise that every physical operation (truck, forklift, compressor, pipeline) deserves a connected, AI-powered safety and efficiency layer — is the most commercially validated proof that the IoT market has produced for pure-play connected operations.

Samsara’s Connected Operations Cloud provides fleet management (GPS tracking, route optimization, driver behavior monitoring), video-based safety (AI-powered dashcam analysis that detects drowsiness, phone use, and unsafe driving patterns in real time), industrial monitoring (equipment sensors and asset tracking for non-vehicle industrial assets), and workflow management for field operations. Its AI-powered platform processes trillions of data points from tens of thousands of customers to train safety and efficiency models that continuously improve across the entire customer base. The average factory floor now uses 178 IoT sensors per 10,000 square feet per recent industry data — Samsara captures a growing share of industrial sensor deployments beyond its fleet management origins.

Bosch is the IoT company that coined “AIoT” — the strategic integration of artificial intelligence and Internet of Things — as the defining evolution of its connected technology strategy. The Bosch Group (€91+ billion annual revenue) deploys IoT technology across its automotive components, industrial automation, home appliances, and energy businesses — with over 1 billion Bosch devices in the global IoT ecosystem. In 2024, Bosch sold its Bosch IoT Suite to Cumulocity (Software AG’s IoT platform, which regained independence from Software AG in January 2025) — signaling the same pattern as PTC’s ThingWorx divestiture: large conglomerates exiting horizontal IoT platform businesses to focus on domain-specific IoT applications where their product expertise creates genuine competitive advantage.

Bosch’s AIoT strategy focuses on three domains: automotive IoT (connected vehicles, driver assistance, telematics), smart home IoT (Bosch Home Connect for connected appliances, Bosch Smart Home for building automation), and industrial AI (Bosch Rexroth for machine connectivity, AI-powered quality inspection in manufacturing). Bosch IoT Insights provides a cloud service for ingesting, analyzing, and storing sensor data from Bosch devices. The company’s claim that “AIoT — the fusion of AI with IoT — is transforming data into actionable intelligence across its entire business ecosystem” reflects the strategic direction that every serious IoT company is pursuing: moving from connectivity infrastructure to AI-powered operational intelligence.

• €91B+ Bosch Group revenue; 1B+ devices in global IoT ecosystem
• AIoT strategy: AI + IoT fusion across automotive, home, and industrial domains
• Sold Bosch IoT Suite (2024): focused on domain-specific AIoT applications

• Automotive IoT: connected vehicle, ADAS sensor, and telematics expertise

ThingWorx and Kepware are the newly independent industrial IoT platform and OT connectivity businesses that PTC completed divesting to private equity firm TPG on March 16, 2026 — for approximately $600 million in cash proceeds. This is the most recent major IoT divestiture event in the industry and deserves inclusion on this list precisely because thousands of manufacturing enterprises depend on ThingWorx and Kepware as their IIoT platform and OT connectivity infrastructure. ThingWorx is a comprehensive IoT platform for industrial enterprises that connects systems, analyzes data, and enables remote device management. Kepware facilitates connectivity between industrial automation devices and applications — acting as the communication bridge that translates between industrial protocols (OPC-DA, OPC-UA, Modbus, DNP3, EtherNet/IP) and modern data formats.

Under TPG ownership, ThingWorx and Kepware join a consolidating industrial IoT portfolio that TPG has been building through acquisitions — including GE Vernova’s Proficy industrial software business. The strategic thesis: private equity can build a meaningful independent industrial IoT software company by combining complementary assets that were undervalued as non-core divisions of larger technology companies. For existing ThingWorx and Kepware customers — which span discrete manufacturing, oil and gas, utilities, and process industries globally — the key questions are product investment continuity, support quality, and roadmap visibility under new ownership. The combined assets generated approximately $200 million in annual revenue under PTC.

• Completed PTC divestiture March 16, 2026 for ~$600M; new owner: TPG
• ThingWorx: IIoT platform for industrial application development and device management
• Kepware: OT data connectivity for 150+ industrial protocols (OPC, Modbus, DNP3)
• ~$200M annual revenue; global manufacturing customer base
• TPG consolidation: adding to Proficy and other industrial IoT assets
• IDC MarketScape 2024 Leader designation (announced Jan 2025)

NVIDIA’s inclusion on this IoT list reflects the fundamental shift in what IoT means in 2026: the most valuable IoT applications are not about connectivity — moving sensor data to the cloud — but about intelligence — making AI-powered decisions at the point of data generation without cloud round-trip latency. NVIDIA is the company that has made AI inference at the edge economically viable at IoT scale. Its Jetson Orin family — system-on-modules providing up to 275 TOPS (tera operations per second) of AI performance — enables manufacturing quality inspection, autonomous vehicle perception, smart city surveillance analytics, and warehouse robot navigation at edge devices that cost $200–$800 rather than $10,000+ server-class GPU clusters.

NVIDIA’s IoT ecosystem is built on three foundations: Jetson (edge AI hardware for robots, cameras, and industrial gateways), Isaac (robotics development platform and simulation environment), and CUDA (the software ecosystem that has made NVIDIA’s GPUs the default training and inference platform for the AI models that run on IoT edge devices). NVIDIA’s Metropolis platform provides a framework for building smart city and industrial AI video analytics applications on Jetson hardware. As IoT deployments increasingly require on-device AI inference — running object detection, anomaly detection, predictive maintenance models locally on edge devices — NVIDIA’s position as the default AI computing platform converts directly into IoT market relevance.

• Jetson Orin: up to 275 TOPS edge AI; $200–$800 for manufacturing/robotics IoT
• Isaac robotics platform: simulation + deployment for autonomous industrial robots
• Metropolis: smart city + industrial AI video analytics on Jetson
• CUDA ecosystem: software and model library enabling on-device AI inference
• Part of $130B+ NVIDIA revenue; AI compute leadership extending to edge
