GraniteShares aims to launch the Speed of Light AI ETF focusing on photonics, enhancing AI infrastructure with faster data processing.

GraniteShares has filed paperwork with the SEC for a new fund called the Speed of Light AI ETF. This unique ETF focuses on photonics, a sector utilizing light technology for faster data transmission and processing. Rather than relying on traditional electron-based methods, photonics allows data to move through optical pathways, enhancing speed and diminishing energy consumption.

This development occurs amidst a surge in demand for improved AI infrastructure, driven by the increasing power requirements of AI training and inference workloads. The technology aims to address significant energy challenges, positioning photonic computing as a viable solution for sustainable AI scaling.

GraniteShares is becoming known for its aggressive expansion in the thematic ETF market. Just one day prior to this filing, the firm introduced autocallable ETFs centered on notable stocks such as Super Micro Computer and MARA Holdings, pushing further into the realm of AI and blockchain themes. Autocallable ETFs, which can yield automatic redemptions under certain conditions, are more common in Europe and Asia than in the US.
