In Q3 2022, PitchBook2 estimated the total market for AI chips to be approximately $23B growing to almost $55B by 2025. In an earlier report on the same subject, Pitchbook acknowledged the long-term potential for deployment of photonic processors as replacements for GPUs in data centers, but did not estimate the current or future market size for such chips. Celestial AI, a customer of POET, reported in its announcement of its Series A funding in February 2022 that its accelerator products serve an addressable market that is projected by Omdia to exceed $70B in 2025 . POET estimates that light source components of the AI chip market will range between 1% and 5% of the light-based portion of the AI chip market.
