Apple Watch dominates Edge AI‑capable smartwatch shipments, accounting for 90% of the market in Q1 2026, according to Counterpoint Research. Edge AI penetration across the broader smartwatch market rose 70 % YoY, reaching 25% in the same quarter.

Edge AI refers to artificial intelligence that runs directly on a device’s own chip. On the Apple Watch, the onboard S9 chip with its 4‑core Neural Engine detects irregular heartbeats and falls in real time, eliminating the need to send data to a paired iPhone or cloud server.

Other brands are catching up: Huawei introduced the Kirin W80 in 2025 to power its Celia voice assistant locally, Qualcomm is launching Snapdragon Wear Elite this year, and Google is preparing a Tensor‑based wearable chip. Ambiq’s Apollo platform offers a software‑driven alternative, running AI inference on vector‑core silicon via Arm’s Helium extensions.

Health monitoring remains the primary use case. Counterpoint data shows blood‑pressure monitoring shipments doubled and sleep‑apnea detection tripled YoY, with industry eyes now on diabetes detection. Apple’s early lead sets a high bar, but cheaper smartwatches may leverage Ambiq or software solutions to approximate Edge AI functionality.
