SoftBank Acquires U.S. Ampere Computing for $6.5 Billion

The acquisition strengthens SoftBank's AI infrastructure strategy and its Arm-based technology ecosystem, pending regulatory approvals.

SoftBank will acquire Ampere Computing, a U.S.-based chip designer specializing in high-performance, energy-efficient processors for AI and cloud computing, in an all-cash deal worth $6.5 billion.
Ampere will operate as a wholly owned subsidiary of SoftBank, retaining its headquarters in Santa Clara, California, and its current leadership under founder Renee James.
The deal aligns with SoftBank's broader AI strategy, complementing its investments in AI infrastructure projects like Stargate and partnerships with OpenAI.
Ampere's major investors, Oracle and Carlyle Group, will sell their stakes as part of the acquisition, which is expected to close in the second half of 2025, pending U.S. regulatory approvals.
SoftBank plans to integrate Ampere's Arm-based CPU expertise into its ecosystem, further advancing its AI and computing capabilities.
