onsemi to buy Synaptics in $7B bet on physical AI
What's the deal? Chipmaker onsemiDealroom has a profile for this one. Try Dealroom → has agreed to acquire SynapticsDealroom has a profile for this one. Try Dealroom → in an all-stock deal worth roughly $7 billion.
The agreement, announced June 25, 2026, values Synaptics at a 19% premium to its recent share price, with shareholders receiving 1.350 onsemi shares per Synaptics share.
onsemi wants Synaptics' edge AI, wireless connectivity, and human-machine interface technology to push beyond its core power and sensing chips.
Why now? AI is moving out of the data centre and into the physical world — cars, factories, and devices that sense, decide, and act in real time.
onsemi is betting that this shift, which it calls "Physical AI," demands chips that combine power, sensing, connected compute, and control. Synaptics fills the compute and connectivity gaps.
The deal could expand onsemi's total addressable market by $30 billion, to $243 billion by 2030.
What could go wrong? All-stock deals tie both companies' fortunes to onsemi's share price, exposing shareholders to market swings before the transaction closes.
Integrating Synaptics' software and ecosystem into a hardware-focused chipmaker carries the usual execution risk. The promised $30 billion market expansion also depends on Physical AI living up to its hype.
The signal: Chipmakers are racing to position themselves for the next AI wave, betting that growth lies at the edge, not just in the cloud.
"As artificial intelligence moves beyond the cloud and into the physical world, the next phase of innovation will depend on systems that can sense, decide, act and adapt in real time," said onsemi chief executive officer Hassane El-Khoury.
The deal reflects a broader scramble among semiconductor firms to own the full stack — from power to compute — as machines grow smarter.
