SoftBank Expands Its AI Footprint with $6.5 Billion Purchase of Ampere Computing

SoftBank Group Corp. announced on Wednesday its plan to acquire semiconductor designer Ampere Computing in a significant $6.5 billion deal, aimed at strengthening its investments in artificial intelligence (AI) infrastructure. The acquisition is part of SoftBank’s broader strategy to harness advanced computing capabilities, which are seen as essential for the future landscape of AI and Artificial Super Intelligence (ASI).

Amplifying AI Infrastructure

In a statement reflecting on this acquisition, Masayoshi Son, SoftBank’s chairman and CEO, emphasized the critical role of advanced computing power in shaping the future of ASI. He stated, “The future of Artificial Super Intelligence requires breakthrough computing power. Ampere’s expertise in semiconductors and high-performance computing will help accelerate this vision and deepens our commitment to AI innovation in the United States.”

Ampere Computing, based in Silicon Valley, specializes in creating high-performance data-center processors leveraging technology developed by Arm Holdings Plc. This acquisition marks a pivotal move for SoftBank, as it aligns with its increasing focus on AI technologies and infrastructure development.

The Deal’s Structure and Future Prospects

As part of the acquisition, Ampere’s major investors, the Carlyle Group and Oracle Corporation, will divest their stakes in the company. However, Ampere will retain its name and continue operating as a wholly owned subsidiary of SoftBank. The transaction is anticipated to close in the latter half of 2025.

Renee James, the founder and CEO of Ampere, expressed enthusiasm about the acquisition, stating, “With a shared vision for advancing AI, we are excited to join SoftBank Group and partner with its portfolio of leading technology companies.” This partnership is expected to create synergies that drive innovation and accelerate developments in AI technologies.

SoftBank’s Vision for AI Expansion

SoftBank has a long-standing commitment to AI investments and has been strategically building its AI portfolio over the years. Notably, the company acquired U.K.-based chip designer Arm in 2016 and subsequently took the company public in 2023. Earlier this year, SoftBank collaborated with Oracle and OpenAI to launch the Stargate initiative, a monumental $500 billion joint venture aimed at establishing AI data centers across the United States.

Furthermore, recent reports have indicated SoftBank’s plans to amplify its investment in OpenAI, starting with an injection of $40 billion in new funding. This aligns with Son’s vision, as he continues to advocate for AI technologies, musings on the evolution of Artificial Super Intelligence into what he calls Super Wisdom—an aspiration he believes will ultimately contribute to the happiness of humanity.

Conclusion

In summary, SoftBank’s $6.5 billion acquisition of Ampere Computing serves as a critical step towards enhancing its AI infrastructure capabilities. The combined expertise of both companies is projected to accelerate the development of high-performance computing solutions fundamental for advancing artificial intelligence technologies. As SoftBank continues to bolster its investment strategy, industry stakeholders will be closely monitoring its initiatives and partnerships in the evolving AI landscape.
