Two developments signal mixed signals for CUDA's ecosystem. First, the open-source NVK Vulkan driver for Nvidia GPUs has added experimental DLSS support by importing Nvidia's pre-baked CUDA binaries (CuBIN files) via the VK_NVX_binary_import extension, as reported by Tom's Hardware source 1. This workaround closes a gap between Nvidia's proprietary driver and its open-source counterpart but remains limited to GPUs with compatible bytecode and is behind an experimental flag due to known bugs. The driver's lead developer noted at XDC2025 that NVK runs at ~50% of the official driver's speed and is 'barely keeping the lights on'. Separately, a prediction market on Manifold Markets source 2 shows consensus at 56.95% that CUDA will remain a monopoly for GPU software through 2027, indicating some uncertainty but still a majority view that CUDA's dominance persists. Together, these events suggest incremental openness in the CUDA ecosystem may reduce lock-in concerns but does not yet threaten CUDA's position; the experimental nature and performance limits of NVK's approach indicate no near-term shift.
