SoftBank Group is making another bold move in the artificial intelligence (AI) industry with its latest acquisition. The Japanese tech investment giant has announced a $6.5 billion all-cash purchase of Ampere Computing, a U.S.-based chip startup known for its Arm-based data center CPUs.
This deal is part of SoftBank’s increasing investments in AI infrastructure, as the company positions itself at the forefront of the AI revolution.
Why Did SoftBank Acquire Ampere?
SoftBank’s founder, Masayoshi Son, has a history of making ambitious bets on emerging technologies. His latest vision focuses on artificial superintelligence, which he believes will require unprecedented computing power. This explains the decision to acquire Ampere, a company that designs high-performance, energy-efficient chips used by cloud computing giants like Oracle.
The acquisition follows SoftBank’s recent investments in:
OpenAI, the company behind ChatGPT
The Stargate Project, an initiative to build AI-focused data centers in the U.S.
Cristal, a joint venture with OpenAI to develop AI solutions for businesses in Japan
By adding Ampere to its growing AI ecosystem, SoftBank is strengthening its ability to provide the next-generation computing power needed for AI advancements.
Ampere’s Rise and Competitive Landscape
Founded in 2018 by Renee James, a former Intel president, Ampere developed custom CPU cores for data centers. Unlike most chip startups, which rely on off-the-shelf designs, Ampere built its own custom Arm-based processors. This gave it an edge over competitors, including Intel and AMD, by offering better efficiency and performance.
However, competition has been tough. Google initially used Ampere’s chips but later shifted to developing its own Axon CPUs with help from Arm. Similarly, other major tech firms have invested in their in-house chip designs, making it challenging for independent chipmakers like Ampere to scale.
Despite this, SoftBank sees long-term potential in Ampere’s technology. With SoftBank’s backing, Ampere could become a key player in AI computing, leveraging the synergy between Arm Holdings (which SoftBank owns) and its AI investments.
SoftBank’s Risky but Bold AI Strategy
SoftBank’s AI push comes at a time when AI-related stocks are soaring, making acquisitions expensive. While Son has a track record of spotting major tech trends early, his investments haven’t always worked out.

For example:
WeWork, once a high-profile SoftBank-backed company, collapsed despite billions in funding.
The Vision Fund, SoftBank’s massive investment vehicle, saw significant losses due to risky bets on tech startups.
However, if Son’s vision for AI supercomputing plays out, this Ampere acquisition could place SoftBank at the center of the next big technology wave.
What’s Next?
With AI demand skyrocketing, SoftBank’s acquisition of Ampere could prove to be a strategic masterstroke. By integrating Ampere’s chips with Arm’s architecture and its AI investments, SoftBank aims to create a powerful ecosystem that fuels the future of AI computing.
But will this bet pay off, or will it be another risky gamble? Only time will tell.
