StoneX has scheduled the second edition of the Nuclear Innovation Summit for September 23-24, 2026 — a closed-door event for institutional investors taking place across Knoxville and Oak Ridge, Tennessee. Fifteen nuclear companies, both public and private, will pitch to an audience of fund managers and financial professionals looking for real opportunities in the nuclear sector.
Day one, on September 23, is hosted at the Marriott Knoxville Downtown and features management team presentations, two thematic panels, and pre-scheduled one-on-one meetings with investors, capped by a cocktail reception. On September 24, attendees board buses to Oak Ridge National Laboratory, where Q&A sessions with department heads and facility tours take center stage. Representatives from the GAIN program — the U.S. Department of Energy’s Gateway for Accelerated Innovation in Nuclear — will be on-site. Oak Ridge is no arbitrary backdrop: the laboratory was founded in 1943 as part of the Manhattan Project and has remained one of the world’s leading nuclear research centers ever since.
The companies confirmed as of September 16 span the full value chain: from uranium enrichment with Centrus Energy Corp. and Urenco, to modular reactors with NuScale Power Corporation and Terrestrial Energy, to microreactors with Radiant Nuclear and Deployable Energy. The lineup also includes Kyoto Fusioneering for fusion, Deep Fission for underground reactors, Scaled Atomics, StarCore Nuclear, NuCube Energy, First American Nuclear, Terra Innovatum Global, and ONE Nuclear Energy in conjunction with Hennessy Capital Investment Corp. VII. The field covers a wide range of technologies — fast reactors, molten salt reactors, next-generation light water reactors — with both publicly listed and privately held companies represented.
The event’s marketing partner is B2i Digital, which distributes content to a media network reaching 330 million monthly readers and a community of 1.7 million investors. What sets this summit apart from traditional industry gatherings is its combination of a typically financial format — roadshow-style presentations and institutional meetings — with an operational visit inside a national laboratory. This is not a trade show: attendees gain access to the places where nuclear research actually happens.
The signal coming from Knoxville is clear. Institutional capital is paying closer attention to nuclear energy, and events like this one accelerate the selection process: investors can compare vastly different technologies over two days, with direct access to the teams developing them. If the inaugural edition established the format, the second consolidates it with a broader participant roster. Future editions may measure the sector by a different standard — not how many companies pitch to investors, but how many close deals afterward.
