onsemi to Buy Synaptics in ~$7 Billion All-Stock Deal to Chase ‘Physical AI’
onsemi agreed to acquire Synaptics in an all-stock deal worth about $7 billion to combine power and sensing chips with Edge AI compute for automotive and industrial “Physical AI.”
TL;DR — onsemi agreed to acquire Synaptics in an all-stock deal valued at about $7 billion (enterprise value), pairing its power and sensing chips with Synaptics’ Edge AI compute to target “Physical AI” in cars and industry.
The semiconductor industry’s consolidation wave rolled on this week. On June 25, 2026, onsemi agreed to acquire Synaptics in an all-stock deal valued at about $7 billion.
The deal
onsemi will acquire Synaptics in an all-stock transaction the companies value at roughly $7 billion in enterprise value. (Bloomberg framed the equity value nearer $6 billion — the two figures measure different things.) The goal is "Physical AI": pairing onsemi’s strength in power, sensing and control with Synaptics’ Edge AI compute, wireless connectivity and human-machine interfaces, aimed at automotive and industrial markets.

What they said
"As artificial intelligence moves beyond the cloud and into the physical world... this shift towards Physical AI will require Power, Sense, Connected Compute and Control to work together seamlessly. The addition of Synaptics helps position onsemi at the intersection of these four pillars." — Hassane El-Khoury, President & CEO, onsemi
Synaptics CEO Rahul Patel said the all-stock structure lets "our shareholders... participate in the compelling growth and value creation opportunities ahead."
Why it matters
- Edge AI is the new battleground. As inference moves into devices and machines, chipmakers want the full sense-decide-act stack under one roof.
- All-stock signals conviction. Both sets of shareholders share the upside — and the integration risk.
- More consolidation ahead. A $7B tie-up keeps 2026’s semiconductor M&A wave going.
