Smart Home Market Size: Why the Estimates Differ So Much

When consumers search for “smart home market size,” they often encounter strikingly different figures. This is not because any single source is wrong, but because research firms use materially different methodologies. This article draws on publicly available data from multiple firms to help readers understand where these discrepancies come from.

Device Shipments: IDC’s Baseline

According to IDC’s Worldwide Quarterly Smart Home Device Tracker (Q4 2024), global smart home device shipments reached approximately 892.3 million units in 2024, growing just 0.6% year-over-year. Growth is expected to recover to 931.1 million units in 2025 (+4.4%), with a 2024–2028 CAGR of 5.6%, reaching 1.1 billion units by 2028. IDC tracks physical device shipments—a relatively standardized and cross-verifiable metric.

Revenue Estimates: Four Firms, Four Numbers

The divergence widens considerably when measuring market revenue:

Firm Estimate Notes
Statista ~$159.5B (2026) Focuses on consumer retail revenue
Global Market Insights $172B (2025); $186.3B (2026) Includes some B2B and service revenue
Fortune Business Insights $147.5B (2025) More conservative device-sales scope
MarketsandMarkets $230.8B (2026) Includes services, solutions, and B2B

All estimates above were published during the 2026 update cycle. The core reasons for divergence include: whether installation and maintenance services are counted, whether commercial (B2B) deployments are included, whether software subscriptions and cloud platform fees are factored in, and how broadly “smart home” is defined. For example, MarketsandMarkets uses a wide scope that encompasses enterprise IoT solutions, while Statista focuses more narrowly on consumer retail.

Regional Reference

Global Market Insights estimates the North American smart home market at approximately $56.2 billion in 2025, making it one of the largest single-region markets globally.
