Top Companies in IoT Market: AWS, Microsoft, Huawei, Cisco and Intel Lead Global Expansion
The global Internet of Things (IoT) market is set for significant expansion, projected to grow from USD 547.06 billion in 2025 to USD 865.20 billion by 2030, according to MarketsandMarkets, reflecting a 9.6% CAGR over the forecast period. This growth is largely fueled by rapid digital transformation, increasing deployment of connected devices, and the maturation of cloud, AI, edge computing, and 5G ecosystems. As billions of devices continue generating real-time data, enterprises worldwide are leveraging IoT to enhance operational efficiency, customer engagement, and decision-making.
Governments are also accelerating IoT adoption through investments in smart cities, energy-efficient buildings, intelligent transportation, and digital healthcare platforms. The falling cost of sensors and cloud-based platforms is helping small and medium-sized businesses adopt IoT solutions that were once accessible only to large enterprises. At the same time, sustainability initiatives are driving demand for predictive maintenance, remote monitoring, and resource optimization powered by IoT analytics.
The global IoT landscape is led by AWS (US), Microsoft (US), Huawei (China), Cisco (US), and Intel (US), all of whom continue to expand through partnerships, acquisitions, and new product developments. These companies collectively hold an estimated 28–38% market share, supported by strong portfolios in cloud, connectivity, edge intelligence, and cybersecurity.
In October 2025, AT&T and Ericsson launched the AT&T IoT Marketplace, a cloud-based platform hosted on Microsoft Azure that simplifies provisioning and billing for industries such as logistics and healthcare. Powered by Ericsson’s Digital Experience Platform, the solution demonstrates how major vendors are forming alliances to accelerate IoT adoption.
AWS delivers one of the most comprehensive cloud-driven IoT ecosystems, including AWS IoT Core, IoT Greengrass, and IoT Analytics, enabling secure device connectivity and edge processing at scale. Microsoft anchors its IoT strategy through Azure IoT services and Azure Sphere, empowering smart city, industrial, and automation use cases worldwide. Huawei remains a dominant force in Asia and emerging markets, integrating AI, cloud, and connectivity in end-to-end IoT deployments. Cisco focuses on secure networking and device management, while Intel supplies the processing power behind next-gen edge computing and AI-enabled devices.
With IoT deployments expanding across manufacturing, transportation, energy, retail, and healthcare, leading vendors are expected to drive the next phase of innovation through integrated IoT–AI–5G ecosystems. As organizations shift toward automation, predictive intelligence, and connected operations, IoT will continue to evolve from a technology enabler into a core pillar of global digital infrastructure.
