Graphcore
UK maker of IPU chips for AI, now a SoftBank-owned research unit after its business failed.
Graphcore's run as an independent Nvidia rival ended in 2024; it now exists inside SoftBank, with its future tied to whether a chip called Izanagi finds outside buyers.
Graphcore designed computer chips meant to compete with Nvidia in the artificial intelligence market. The company failed at this goal, losing $165 million in 2023 while making only $4 million in sales, and its deal with Microsoft fell apart. Nvidia won because it built a locked-in ecosystem that customers depend on, and large tech companies also started making their own chips instead of buying from independent sellers like Graphcore. Now Graphcore is owned by SoftBank and survives as an internal research team rather than an independent business. The one thing that could change this picture is whether a new chip called Izanagi, being developed with a partner, gets sold to outside customers under Graphcore's name with real revenue by the end of 2026, or simply disappears into SoftBank's internal operations.
Companies House FY2024-2025 filing shows external revenue figures beyond SoftBank-internal work. Would show whether independent commercial demand exists at all.
SoftBank announces further capital injections or, alternatively, restructuring/absorption of Graphcore into its platform. Would show whether SoftBank still values Graphcore as a distinct entity or is winding it down.
- 2023 revenue: $4m
- 2023 pre-tax loss: about $165m
- 2024 SoftBank buyout: $500 to 600m, vs $2.77bn 2020 peak
- Near-zero external revenue ($4m in 2023) leaves company entirely dependent on SoftBank capital.
- Nvidia's CUDA ecosystem lock-in continues to block Graphcore's commercial adoption.
- Equity holders and option grantees received $0 in the 2024 acquisition, no disclosed liquidity path since.
- Izanagi chip may be absorbed into SoftBank's internal platform rather than sold as a Graphcore product.
- Broader 2026 AI-stock volatility could constrain SoftBank's future funding of subsidiaries like Graphcore.
| Rival | Direction | Evidence |
|---|---|---|
| Nvidia | losing to | CUDA ecosystem lock-in cited in Azure deal collapse, 2022-10-08 writedown of ~$1bn |
| AWS Trainium / Microsoft Maia | gaining on | Named as hyperscaler custom-silicon competitors squeezing merchant chip vendors, 2026-02 |

- Is Graphcore profitable in 2026?
- No. Graphcore reported just $4m revenue in 2023 against pre-tax losses of roughly £131m (~$165m), per company accounts cited by Sifted on 2024-10-04. No FY2024 or FY2025 revenue figures have been publicly disclosed since SoftBank acquired the company in July 2024, and it now operates as a subsidized captive R&D unit rather than a standalone profit-seeking business.
- Who owns Graphcore now?
- SoftBank Group Corp of Japan acquired Graphcore in a deal announced 2024-07-11, reportedly worth $500 to 600 million, about one-fifth of Graphcore's 2020 peak $2.77bn valuation. As of April 2026 SoftBank injected a further $457m via UK Companies House filing, making Graphcore a wholly owned, capital-dependent subsidiary.
- Who is Graphcore's biggest competitor?
- Nvidia. Its CUDA software ecosystem dominates the AI accelerator market and is widely cited, including by The Times on 2022-10-08, as the reason Graphcore's 2019 Microsoft Azure supply deal collapsed, contributing to a roughly $1bn valuation writedown. Hyperscaler custom chips like AWS Trainium and Microsoft Maia add further pressure.
- Could AI replace Graphcore's business?
- Not directly, Graphcore sells AI training and inference hardware rather than a service AI models perform, but the AI boom has not translated into sales: 2023 revenue was just $4m against $165m in losses, per Sifted's 2024-10-04 reporting, as customers overwhelmingly chose Nvidia GPUs and hyperscaler silicon instead.
- What happened to Graphcore's Microsoft Azure deal?
- Graphcore's landmark 2019 deal to supply Microsoft Azure with IPU chips fell through around 2022, contributing to roughly a $1bn valuation writedown, according to The Times on 2022-10-08. The company also exited China in 2023-2024 due to US export-control restrictions, further shrinking its addressable customer base.
- What is the Izanagi chip and does Graphcore still make its own products?
- Izanagi is a next-generation chip Graphcore is co-developing with fellow SoftBank subsidiary Ampere Computing for SoftBank's Stargate data-center buildout, reported by Jon Peddie Research on 2026-06-15. As of mid-2026 it remains unresolved whether Izanagi ships as a Graphcore-branded product or gets absorbed into SoftBank's internal platform.
