A company developing an underground nuclear reactor in Parsons is moving forward with plans to become publicly traded.

California-based Deep Fission has filed paperwork with the U.S. Securities and Exchange Commission for an initial public offering. The company plans to offer 2.5 million shares at a price between $16 and $18, with the goal of raising more than $40 million. Deep Fission is developing its Gravity Reactor project at the Great Plains Industrial Park in Parsons.  They have already drilled their first data-gathering well and plan next to demonstrate a commercial-scale borehole and deploy a prototype reactor underground.

According to the filing, the company hopes to apply for a commercial license from the U.S. Nuclear Regulatory Commission in early 2027. The SEC filing also notes the technology remains unproven and could face delays, increased costs or other challenges as development continues. The proposed stock offering would trade on the Nasdaq exchange under the ticker symbol F-I-S-N if approved.
