From an interview with Brian Burke, NVIDIA PR Gaming Technology, Esports & Consumer VR:
"Brian: Cyberpunk 2077 uses the industry standard DirectX Ray Tracing API. It will work on any DXR-compatible GPU. Nothing related to Cyberpunk 2077 ray tracing is proprietary to NVIDIA."
(Previous comments indicating otherwise by CDPR art director Jakub Knapik, were made before the launch of AMD's RDNA 2 cards)
EDIT: Ah, my first thread created and I forgot to specify which game in the title
