SoftBank Group has injected more than $450 million into British AI chipmaker Graphcore as part of its expanding push into artificial intelligence infrastructure and hardware, according to reports.
A Companies House filing showed Graphcore issued a single share valued at roughly $457 million in April. A company spokesperson confirmed the funding came from SoftBank. The report said the investment is only part of the funding Graphcore is expected to receive from SoftBank this year.

SoftBank acquired Graphcore in 2024 to strengthen its ambitions in artificial general intelligence and semiconductor development. Once viewed as a potential rival to Nvidia, Graphcore struggled commercially before the takeover.
SoftBank has aggressively expanded its AI investments through partnerships involving OpenAI, Oracle, Arm, and Ampere Computing. Graphcore is also continuing global expansion plans, including a proposed £1 billion AI campus project in Bengaluru, India.
