How to Invest in Radiant Pre-IPO

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.

How to buy Radiant stock?

Since it's not listed on public markets, many investors are unable to purchase Radiant stock. But accredited investors may be able to gain positions even though the stock hasn't debuted on public markets with an IPO. Platforms like Forge Global (FRGE 0.42%) provide accredited investors an opportunity to invest in privately held companies like Radiant.

Those who don't qualify as accredited investors are not completely out of luck, though. There are other nuclear energy stocks to consider that operate in similar ways to Radiant.

1. NuScale Power

Unlike Radiant with its Kaleidos microreactor, NuScale Power (SMR -14.18%) has its sights on disrupting the nuclear energy industry with the NuScale Power Module. An SMR that has a 77-MW generating capacity, the NuScale Power Module can be scaled with up to 11 other modules to meet the specific power needs of its customers.

NuScale Power has the potential to gain a first-mover advantage over would-be competitors. It's the first and only SMR to have its designs certified by the U.S. Nuclear Regulatory Commission. In addition to powering data centers, NuScale Power recognizes water desalination, enhancing grid resiliency, and green hydrogen production as possible applications of its technology.

With a strong balance sheet that features no debt and $521.4 million in cash, cash equivalents, and short-term investments, NuScale Power is well-positioned as it strives to reinvigorate the nuclear energy industry.

2. Oklo

Another name growing in popularity on the nuclear energy landscape is SMR developer Oklo (OKLO -17.82%). Founded in 2013, Oklo is developing a nuclear power solution called Aurora, which will have a 15- to 75-MW generating capacity. NuScale Power uses new fuel for its SMRs, but Oklo is designing Aurora to have the flexibility to use either new fuel or recycled fuel. Distinguishing itself from peers, Oklo characterizes itself as the "only advanced nuclear company pursuing a fully integrated recycled fuel business, providing the company with a structural long-term supply chain and cost advantage relative to competitors."

Already, Oklo has generated strong demand from customers. In 2024, it signed a nonbinding agreement with Switch -- a provider of artificial intelligence (AI), cloud, and enterprise data centers -- to deploy 12 gigawatts in Aurora powerhouse projects through 2044. Additionally, it executed two letters of intent to provide an additional 750 MW of energy for data center customers.

3. Centrus Energy

Unlike SMR developers NuScale Power and Oklo, Centrus Energy (LEU -21.59%) supplies nuclear fuel -- both low-enriched uranium (LEU) and high-assay low-enriched uranium (HALEU) -- and services to companies in the nuclear energy industry. Providing a variety of enriched uranium, Centrus Energy brandishes itself as the "world’s most diversified supplier of enriched uranium fuel." It also retains a competitive advantage over peers in that it's the only company that the Nuclear Regulatory Commission has licensed for HALEU production for both commercial and defense applications.

Tracing its history back to 1992, Centrus Energy is a well-established company that provides a better opportunity for those looking for nuclear energy exposure who are also uninterested in a higher-risk investment. From 2020 through 2024, Centrus Energy has steadily grown revenue from $247 million to $442 million. During that time, it has also generated consistent profits and free cash flow.

People who don't meet the criteria for accredited investors and who are motivated to buy shares of one of these other nuclear energy choices only have to take a few simple steps to become shareholders:

1. Open your brokerage app: Log in to your brokerage account where you handle your investments.
2. Search for the stock: Enter the ticker or company name into the search bar to bring up the stock's trading page.
3. Decide how many shares to buy: Consider your investment goals and how much of your portfolio you want to allocate to this stock.
4. Select order type: Choose between a market order to buy at the current price or a limit order to specify the maximum price you're willing to pay.
5. Submit your order: Confirm the details and submit your buy order.
6. Review your purchase: Check your portfolio to ensure your order was filled as expected and adjust your investment strategy accordingly.

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.

ETFs with exposure to Radiant Industries

Since it's a privately held company, investors can't choose an exchange-traded fund (ETF) as a route to gaining exposure to Radiant stock; however, investors can gain direct exposure through the ARK Venture Fund. But there are other ETF options for investors to consider, such as nuclear energy ETFs and clean energy ETFs that offer exposure to companies operating in areas comparable to Radiant.

• ARK Venture Fund (NASDAQMUTFUND:ARKV.X): A mutual fund found under Cathie Wood's ARK Invest umbrella, the ARK Venture Fund provides exposure to both public and private companies that have the potential to disrupt the industries in which they operate. As of June 30, 2025, Radiant had a 2% weighting in the fund, which has annual total fees of 2.9%.
• Global X Uranium ETF (URA -5.14%): With 48 holdings in its portfolio, the Global X Uranium ETF offers broad exposure to the nuclear energy industry. In addition to SMR developers like NuScale Power and Oklo, the ETF has positions in fuel production like uranium producer Cameco (CCJ -1.75%) and uranium enriching specialist Centrus. The ETF has a 0.69% total expense ratio.
• Invesco WilderHill Clean Energy ETF (PBW -5.98%): Providing comprehensive exposure to renewable energy companies, the Invesco WilderHill Clean Energy ETF is a great consideration for investors interested in less concentrated exposure to the nuclear energy industry. Among the ETF's holdings are solar power companies like Sunrun (RUN -8.07%), hydrogen power leaders like Bloom Energy (BE -14.58%), and energy storage specialists like Fluence (FLNC -11.13%). The ETF has a 0.65% total expense ratio.
