As political support grows and technological advances continue, it appears we're on the verge of a renaissance in nuclear energy, leading many to consider growth opportunities, such as those in Radiant stock.
Former employees at SpaceX, Doug Bernauer and Bob Urberger, founded Radiant in 2020 with the goal of developing the nuclear-powered Kaleidos, which they characterize as "the world’s first portable, zero-emissions power source that works anywhere." In addition to using helium gas instead of water for cooling, which improves the safety profile, the allure of Kaleidos is that it's small enough to fit in a shipping container and can be installed in a matter of hours.
Small modular reactors (SMRs) -- a nuclear energy solution that provides a safer alternative to traditional nuclear power plants -- typically have generating capacities between 50 megawatts (MW) and 300 MW. The Kaleidos microreactor, however, has a 1 MW generating capacity, helping to reduce the time required to deploy it.
Radiant plans on testing Kaleidos at the Idaho National Laboratory DOME facility by the end of 2026 and making its first commercial delivery in 2028.
Is Radiant publicly traded?
Those looking for Radiant on public markets will be disappointed to find that as of July 2025, Radiant was not a publicly traded company. While most investors may not have access to Radiant stock, the company has held several funding rounds. In May 2025, for example, the company announced that it had completed a $165 million Series C round that included investments from the Cathie Wood-led Ark Invest among a variety of other venture capital firms.
When will Radiant IPO?
For investors eyeing investment opportunities that provide the potential for significant returns, IPO stocks represent a common consideration. As of July 2025, Radiant has made no indication that it intends on holding an IPO in the near future. Frustrated as growth investors may be to learn that Radian has no plan to hold to holdan IPO, there are still options, as numerous companies plan on holding IPOs in the coming months.
IPO
Is Radiant profitable?
As a privately held company, Radiant isn't subject to the same financial reporting requirements as publicly held companies. Consequently, investors don't have much insight into the company's financial position. If the company proceeds with an IPO, it will have to file Form S-1 with the U.S. Securities and Exchange Commission (SEC), at which point investors will have a better sense of where the company stands financially.
Since the company doesn't expect to deliver its first commercial product until 2028, it's reasonable to speculate that the company isn't generating a profit.
Should I invest in Radiant Industries?
Because Radiant hasn't held an IPO, most investors cannot directly purchase shares. Accredited investors, on the other hand, may be able to gain exposure through platforms that provide opportunities to invest in companies prior to them going public.
If Radiant makes an IPO, it will submit regulatory filings, providing insights into its financials. At that point, investors can better decide if an investment in the company is right for them.
