Deep Fission is not primarily trying to reinvent reactor physics; it is attempting to commercialize a borehole deployment model using conventional PWR technology, standard LEU fuel, and established drilling methods. The post-IPO weakness appears driven more by technical selling, limited market awareness, and development-stage skepticism than by a material change in the company's commercial roadmap. Deep Fission's DOE Reactor Pilot Program path is differentiated because the company is advancing the reactor configuration that management intends to commercialize, not merely pursuing a standalone criticality experiment.
