A few years ago, a Graphcore IPO seemed like a strong possibility... but then it was bought by SoftBank Group. Around 2020/2021 Graphcore had raised more than $700m from prominent investors and had an estimated valuation approaching $3b. It had positioned itself as a European AI hardware challenger to NVIDIA. By the time SoftBank acquired Graphcore in 2024, an IPO had started looking a lot less likely, as the company hadn't raised fresh capital for several years, its losses had widened and it had exited China – all factors making fundraising more difficult.
So now, as a wholly owned subsidiary of SoftBank, an IPO any time soon is pretty unlikely (but not entirely off the cards... after all, Arm Holdings was also owned by SoftBank before going public in a high-profile 2023 IPO). You do have the option of investing in SoftBank, as that's publicly-traded. Note that the movement of SoftBank's stock price will be influenced by more than just the success (or failure) of Bristol-based Graphcore.
SoftBank's primary listing is on the Tokyo Stock Exchange under the ticker 9984. UK trading apps are generally better as supporting US-traded stocks, and SoftBank's also listed under ticker SFTBY on the US OTC market.
