About Kairos Power
Kairos Power is a nuclear energy startup developing fluoride salt–cooled, high-temperature reactors to deliver clean, affordable electricity.
Founded in 2016 by engineers and scientists Edward Blandford, Per Peterson, and Mike Laufer, the company grew out of advanced reactor research at UC Berkeley and related institutions.
Kairos Power’s primary business centers on designing and commercializing small modular reactors using TRI-structural ISOtropic (TRISO) particle fuel pebbles combined with low-pressure molten fluoride salt coolant.
The company is developing its Hermes demonstration reactor in Oak Ridge, Tennessee. The project received regulatory approval in 2023 and represents the first non-light-water reactor permitted in the United States in over 50 years.
Kairos Power is headquartered in Alameda, California, with additional facilities in Albuquerque, New Mexico. The name derives from the ancient Greek word “kairos,” meaning timeliness and a call to action.
Among the new and more nimble class of small modular reactor developers and well-funded nuclear startups like TerraPower, Kairos Power distinguishes itself through an iterative testing approach and has secured major partnerships, including a landmark agreement with Google to supply nuclear reactors for data centers by 2030.
Its future hinges on demonstrating its cost-competitive nuclear technology, accelerating the transition to carbon-free electricity generation to electrify the AI generation.
Here’s an interesting video overview of the company:
Ownership
Kairos Power is a private company, owned by its founders, employees, and possibly some private equity, venture capital, or government organizations. But ownership documentation is limited.
Kairos Power has not been forthcoming with traditional venture capital funding rounds and detailed investor lists and amounts in a number of sources researched.
The most concrete verified funding figure available is the DOE performance-based support of up to $303 million under the ARDP, which is government funding tied to milestones, not direct equity financing.
Though unusual, private companies can avoid disclosures by securing capital without venture capital while remaining tight-lipped about their sources.
As the company grows, it may seek higher-profile investors or more notable capital raises.
IPO Potential
Kairos Power is a mid-stage startup in a capital-intensive industry.
That means it must raise substantial funds and commit to long-term development timelines to be a viable business.
Some startups choose to raise funds from venture capital investors, announcing progress and partnerships along their Series fundraising journey.
Instead, Kairos Power has chosen government grants, potential municipal partnerships, and corporate partnerships with (possibly Alphabet) to fund its ambitions.
Since the timeline for a successful energy demonstration and commercialized energy could be several more years away, a Kairos Energy IPO is not likely until the 2030s.
An S-1 filing (confidentially or publicly) is the most accurate sign that an IPO may be forthcoming. The intent to move forward with an IPO is usually leaked to the press long before the S-1 filing becomes available to the public.
How to Invest in Kairos Power Stock
Investing in Kairos Power is more challenging than a typical startup. The ownership and share structure are not publicly available.
Therefore, retail investors should not expect widespread ownership access, but can monitor the situation as the company grows.
Here are some potential options to own Kairos Power stock before, during, and after the IPO.
1. Invest Pre-IPO
Pre-IPO investment platforms may offer Kairos Power stock for purchase as employees or early investors seek to liquidate shares.
Accredited investors may access shares, provided they are registered on the platform and receive notifications about their availability.
Monitor pre-IPO investing platforms such as Hiive, Equitybee, Augment, Forge Global, and EquityZen for share availability.
If shares become available, expect to pay at least a $10,000 investment minimum, often more.
Non-accredited investors can invest in pre-IPO companies via venture capital funds targeted at retail investors.
Fundrise Venture is an excellent option. However, Kairos Power is not currently in the portfolio.

2. Participate in the Kairos Power IPO through a broker
When a company eventually goes public, ordinary investors can sometimes buy the stock during the IPO at the IPO price.
Often, only Wall Street’s top customers can invest in IPOs. But with a larger IPO like Kairos Power, investors may have an opportunity to access the IPO through participating discount brokers.
Some online brokers (like the ones listed below) allow investors to invest in IPOs for free, even if they have limited funds in their accounts.
TradeStation has a more established track record of accessing more than 400 IPOs and secondary offerings via its partnership with Click Markets (formerly Click Markets).
Robinhood has the advantage of Silicon Valley networks and a history of getting allocations for high-profile IPOs.

3. Buy Kairos Power stock after the IPO
Most retail and institutional investors will need to wait until after the IPO to invest. That date could easily be five years or more away due to the extended timelines well-known in the nuclear industry.
Waiting for the IPO has advantages, such as access to more established financials after the first quarter of trading. Pre-IPO investing has limited financials.
Nuclear power is a promising energy source for powering the AI generation. However, utility companies are not in a fast-scaling industry like AI itself, because of the significant capital and timelines required.
So if and when the company is public one day, the potential for share appreciation will be limited.
Investor Takeaways
Kairos Power is taking an unconventional approach to nuclear energy financing, apparently sidestepping the traditional venture capital path in favor of partnership and grants.
The company’s reliance on government partnerships, corporate agreements like the Google deal, and debt funding suggests a deliberate strategy to maintain control and avoid the disclosures that come with prominent VC backing.
This creates significant barriers for retail investors seeking pre-IPO exposure, making Kairos Power one of the least accessible startups on the Access IPOs radar list.
The extended timeline inherent to nuclear development — where demonstration reactors take years to prove viability — means patient capital and strategic partnerships matter more than rapid scaling.
Investors should recognize that even after a potential IPO (estimated in the 2030s, if ever), nuclear companies face fundamentally different growth trajectories than software or AI firms, limiting share appreciation potential.
The Hermes reactor’s success or failure will ultimately determine whether this capital structure and technology prove advantageous or whether the company eventually needs to court traditional institutional investors.
Interested pre-IPO investors will need to wait for more private funding and transparency before investing in Kairos Power stock.
