Oklo (OKLO) Stock Today, 22 November 2025: Price, Nuclear Breakthroughs and a Reality Check After the Hype

Oklo Inc. (NYSE: OKLO) – the advanced nuclear start‑up that has become a flagship play on AI data‑center power demand – is ending this week on a calmer note after a bruising post‑earnings sell‑off. As investors digest a deeper‑than‑expected quarterly loss alongside major project wins with Siemens Energy, the U.S. Department of Energy (DOE) and the Nuclear Regulatory Commission (NRC), Oklo stock is stuck in the uncomfortable middle ground between breakthrough narrative and harsh financial reality. ^[1]

Oklo stock price today: volatile but still massively up year‑on‑year

As of the latest close, Oklo shares trade at $88.17, up a fraction on the day, with intraday trading having swung between about $79 and $92 on heavy volume of more than 21 million shares.

That small gain masks a rough week:

Oklo stock is down about 10% over the last five trading days, according to Quiver Quantitative’s price data. ^[2]
Over a longer horizon, the stock is still eye‑popping: Simply Wall St data show a ~250% gain over the past year, with a 52‑week high near $193.84 and a low around $17.14. ^[3]

In other words, today’s $88 price leaves Oklo more than 50% below its peak, but still up several‑fold for early believers. That combination of huge prior gains and a sharp recent pullback is exactly what you’d expect from a pre‑revenue, story‑driven name tied to the AI power boom. ^[4]

Why Oklo stock fell this week

Two forces have hit Oklo over the last few sessions:

A broad wobble in AI/data‑center “story stocks”
A Motley Fool column (syndicated via Nasdaq) notes that Oklo dropped roughly 9% on Friday as investors rotated out of speculative AI‑linked names after Nvidia’s latest earnings, despite that report being broadly solid. The article frames Oklo as a no‑revenue, loss‑making company whose prospects are tightly tied to long‑term AI and data‑center electricity demand – exactly the sort of stock that gets sold when markets worry about a bubble. ^[5]
A Q3 earnings miss and widening losses
Oklo’s Q3 2025 earnings on 11 November showed an EPS loss of –$0.20, missing consensus expectations of –$0.13 (a negative surprise of about 54%). The stock initially slid more than 6% in aftermarket trading on the news. ^[6]

Those numbers fed into a narrative that had already been building: Oklo has become one of the most richly valued pre‑revenue companies in the U.S. – above $20 billion at earlier peaks – despite not yet owning an operating plant, holding an NRC license, or having binding power contracts. ^[7]

Q3 2025 earnings: bigger losses, but a huge cash cushion

Under the hood, Oklo’s Q3 results were a classic “high risk, high cash burn” update:

EPS: –$0.20 vs –$0.13 expected. ^[8]
Operating loss: about $36.3 million in Q3, up sharply from roughly $12.3 million a year earlier and from ~$28 million in Q2. ^[9]
Year‑to‑date loss: reports from Longbridge and others put the net loss for the first nine months of 2025 at roughly $64 million, driven largely by higher R&D and scaling costs. ^[10]
Cash burn: management guided for full‑year operating cash outflows in the tens of millions, consistent with a company still deep in development mode. ^[11]

The flip side: Oklo is currently very well funded. Between its SPAC merger, follow‑on equity offerings (including a ~$400 million raise earlier this year) and a recent at‑the‑market program that brought in roughly $540 million in gross proceeds, the company now sits on about $1.2 billion in cash and marketable securities, according to the Q3 call commentary. ^[12]

The result is a textbook venture‑style financial profile:

Zero revenue so far – something Investor’s Business Daily and other outlets highlight bluntly. ^[13]
Rapidly rising operating expenses as the company moves from concept and licensing into groundwork, fuel qualification and long‑lead procurement. ^[14]
A very long runway of cash, but also the clear risk that more equity raises could come if timelines slip or capex climbs.

For investors, the key question is whether that cash pile ultimately funds productive assets – or just buys time in a race against regulatory, technical and competitive headwinds.

Project and regulatory milestones: the bull case in hard news

If the financials are the bear case, Oklo’s project and policy momentum is what keeps bulls engaged. Over the past few months, the company has stacked up some genuinely meaningful milestones.

1. Breaking ground on the first Aurora powerhouse

On 22 September 2025, Oklo held a groundbreaking ceremony at Idaho National Laboratory (INL) for its first commercial powerhouse, Aurora‑INL, under the DOE’s new Reactor Pilot Program. The project is a 75‑MWe sodium‑cooled fast reactor using metal fuel derived from legacy Experimental Breeder Reactor‑II (EBR‑II) material, and is expected to create around 370 construction jobs and 70–80 long‑term operational roles. ^[15]

Construction will be led by Kiewit Nuclear Solutions, a major industrial EPC contractor, under a master services agreement designed to tap its experience with large, complex projects. ^[16]

This is crucial symbolically: unlike many advanced‑nuclear start‑ups that are still in paper‑reactor mode, Oklo now has a shovel in the ground at a specific site with government backing.

2. DOE approval for its Aurora fuel‑fab facility

On 11 November 2025, Oklo announced that the DOE’s Idaho Operations Office had approved the Nuclear Safety Design Agreement (NSDA) for its Aurora Fuel Fabrication Facility (A3F) at INL – the first NSDA approved under the DOE’s Advanced Nuclear Fuel Line Pilot Projects. ^[17]

The NSDA does a few things:

Confirms A3F as part of a federal pilot line to build new fuel supply chains.
Demonstrates a faster DOE authorization pathway (approval came in under two weeks).
Links fuel production directly to Aurora‑INL, with the intent of using recycled metallic fuel to power the reactor. ^[18]

CEO Jacob DeWitte has framed advanced fuel fabrication and recycling as a “key unlock” – not just for solving fuel‑supply constraints but for creating a potential second revenue stream around radioisotopes and fuel services. ^[19]

3. NRC “fast‑track” progress on design criteria

On 30 September 2025, the U.S. NRC accepted Oklo’s Principal Design Criteria (PDC) topical report for review on an accelerated schedule, promising a draft evaluation in early 2026 – less than half the usual timeline. ^[20]

The PDC report essentially sets the safety and performance ground rules that future Oklo applications will reference. Once approved, it can be reused in subsequent filings, reducing repetitive review and (in theory) speeding up the licensing of additional plants. The NRC explicitly tied the move to its broader modernization push and to new federal legislation and executive orders – including the ADVANCE Act and Trump‑era directives – aimed at streamlining advanced nuclear approvals. ^[21]

Given that Oklo’s first license application was rejected in 2022, this new, closer engagement with the regulator is a key narrative pivot for the company. ^[22]

4. Siemens Energy deal derisks a critical piece of Aurora‑INL

The freshest catalyst this week is Oklo’s binding contract with Siemens Energy, announced 19 November 2025. Under the deal, Siemens will design and deliver the power conversion system for Aurora‑INL, including a condensing SST‑600 steam turbine, an SGen‑100A generator, and associated auxiliaries. ^[23]

Importantly, the contract:

Authorizes Siemens to start detailed engineering now.
Allows early procurement of long‑lead components, helping avoid bottlenecks later.
Locks in a partner with deep experience in steam‑turbine and generator systems for a first‑of‑a‑kind advanced reactor. ^[24]

Oklo already had fuel secured from DOE and an allocated site at INL; the power‑conversion system is one of the remaining critical items. Management argues that ticking this box de‑risks the supply chain and schedule for Aurora‑INL and creates a template for future projects.

5. Military and AI‑data‑center optionality

Earlier this year, Reuters reported that the Defense Department’s energy logistics arm issued a notice of intent to award Oklo a power‑purchase agreement for a pilot microreactor at Eielson Air Force Base in Alaska. The project, designed to produce around 5 MW of electricity and heat, is not yet a firm contract but would be owned and operated by Oklo under a long‑term PPA if finalized. ^[25]

Meanwhile, multiple reports – from Wedbush to the Financial Times – describe Oklo as a potential “hold name” for the White House’s nuclear agenda and one of the most aggressive plays on powering energy‑hungry AI data centers, with non‑binding agreements signed with operators such as Switch and Equinix. ^[26]

The bottom line: the company’s pipeline is still mostly MOUs and pilot programs, but it is not short of high‑profile partners or political tailwinds.

Insider selling, institutional buying and what Wall Street thinks

If you want a sense of how polarizing Oklo has become, look at who’s trading the stock.

Heavy insider selling

Quiver Quantitative data show 44 open‑market insider sale transactions and no purchases over the last six months. Those sales include: ^[27]

CEO Jacob DeWitte: 16 sales totaling about 600,000 shares.
Co‑founder/COO Caroline Cochran: another 16 sales, also around 600,000 shares.
CFO Craig Bealmear and other senior executives disposing of significant stakes.

For some investors, that pattern of insiders cashing out after a huge run is a red flag, especially for a company still years away from revenue.

Big institutions are piling in

On the other hand, the same Quiver report shows that in Q3 2025: ^[28]

Mirae Asset, Vanguard, VanEck, BlackRock, UBS and Morgan Stanley all added seven‑ to nine‑figure positions in Oklo.
In total, 439 institutional investors increased their positions, while 237 reduced them.

That mix – heavy insider selling but strong institutional demand – is typical of highly speculative growth stories where professional money managers see a potentially huge payoff, but founders and early backers also want to lock in gains.

Analyst ratings and price targets

Across various aggregators, analyst opinions skew bullish but nuanced:

Quiver counts 13 analysts covering Oklo over the last six months, with a median 12‑month price target around $92 and a cluster of bullish targets between $117 and $175. ^[29]
Recent moves include B. Riley lifting its target from $58 to $129, Wedbush to $150, Barclays to $146 and Goldman Sachs to $117, all with Buy/Overweight‑type ratings. ^[30]
A widely cited Bank of America note this week downgraded Oklo from Buy to Neutral while trimming its target to roughly $111, arguing that the stock price already reflects very optimistic expectations for project execution and AI‑driven demand. ^[31]

Overall, Quiver reports 8 firms with Buy/Outperform/Overweight ratings and none with outright Sell, though some independent commentators and Seeking Alpha contributors argue that Oklo’s valuation remains “unsustainable” relative to its lack of revenue and long road to commercial operations. ^[32]

Key risks investors should keep in mind

Even supporters of the stock are quick to acknowledge how many things have to go right for Oklo.

Regulatory and execution risk
- Oklo’s first NRC license application was rejected; while the current NRC engagement is more positive, approvals for a new reactor design and fuel cycle are far from guaranteed. ^[33]
- Aurora‑INL and A3F must move from groundbreaking and NSDA approval to actual construction, commissioning and safe operation – something no private U.S. fast‑reactor developer has yet done at commercial scale. ^[34]
Technology and proliferation concerns
- The design relies on metal‑fuel, sodium‑cooled fast reactors and recycled plutonium‑bearing fuel, a combination that has drawn criticism from non‑proliferation experts and some nuclear engineers, even as Oklo and DOE argue that the fuel form is highly resistant to misuse. ^[35]
Financing and dilution risk
- Building a fleet of reactors and fuel‑fab facilities will cost far more than the $1.2 billion Oklo currently holds. The company’s own filings and press releases flag the need for substantial additional capital – equity, project finance or both – and warn of potential dilution for existing shareholders. ^[36]
Customer, contract and timeline risk
- Many of Oklo’s agreements, including those with AI‑data‑center operators and the Air Force, are non‑binding or still at the “notice of intent” stage. Timelines to first power (currently guided around 2027–2028 for Aurora‑INL) could slip for regulatory, technical or funding reasons. ^[37]
Valuation and volatility
- FT and other outlets have highlighted Oklo as a poster child for speculative enthusiasm in AI‑linked infrastructure: a >$20 billion valuation at one point, no revenue, and heavy political and narrative support. Stocks like that can move dramatically in both directions on sentiment alone. ^[38]

For anyone considering the name, those risks aren’t footnotes – they’re the core of the investment thesis.

Is Oklo stock a buy, sell or hold after this pullback?

Whether Oklo belongs in a portfolio today depends far more on risk tolerance and time horizon than on this week’s price action.

For high‑risk, long‑term growth investors who are comfortable with binary outcomes, Oklo represents a rare, concentrated bet on three converging themes:
1. A political push to accelerate advanced nuclear deployment,
2. Exploding power demand from AI and cloud computing, and
3. The potential to turn nuclear waste into fuel via advanced recycling. ^[39]
For more conservative or income‑focused investors, the lack of revenue, negative cash flow, regulatory uncertainties and violent share‑price swings make Oklo a textbook “watchlist, not core holding” candidate.

Regardless of profile, a sensible approach to a stock like Oklo typically includes:

Treating any position as speculative, sized small relative to a diversified portfolio.
Tracking cash balances and burn each quarter to gauge how much real runway remains.
Watching for concrete progress: signed, binding PPAs; clear NRC licensing milestones; and credible updates on Aurora‑INL construction and Siemens’ power‑conversion work. ^[40]

Final word

Oklo stock today sits at a crossroads: the share price has come down hard from euphoric highs, yet the company’s funding, government partnerships and project pipeline have never looked stronger on paper. Bulls see that as a rare second chance to enter a transformational story; skeptics see it as the latest chapter in a market that still hasn’t fully priced in execution risk.

Either way, Oklo remains one of the most closely watched tickers in the nuclear and AI‑infrastructure space – and one that is likely to stay volatile as each new milestone either validates or challenges the grand narrative around advanced fission.
