In this piece, we will look at Jim Cramer’s bold predictions about quantum computing and nuclear power stocks.

Throughout his appearances in 2025, Jim Cramer has regularly discussed nuclear power and quantum computing stocks. For both these sectors, Cramer continued to believe that they are long-term plays at best and speculative vehicles at work. For instance, in one of his first shows of the year aired on January 2nd, Cramer cautioned viewers about being too optimistic about the short-term nature of these stocks.

During his Mad Money episode, Cramer remarked:

“This year, I see two themes that I want to caution people about: nuclear power and quantum computing. Both have promise, someday, but that day is not, just not near enough to justify the current valuations for these stocks.”

However, at least for quantum, Cramer appears to be changing his mind. While he’s still undecided about the short-term potential of the quantum computing industry, the CNBC TV host has nevertheless started to discuss the stocks a lot more. For instance, in a recent Squawk on the Street appearance, he commented:

“I’m going all in on what youth wants. They inherit the earth, I have the heart of darkness. I’m trying to get away from that. When Jensen switched and said he’s in on quantum, who am I to say, that the man who the President thought about breaking up the company but said it was too great, I’m going all in quantum.”

13. D-Wave Quantum Inc. (NYSE:QBTS)

Number of Hedge Fund Holders In Q2 2025: 24

Date Of Cramer’s Remarks: 12-19-24

Share Price Performance Since Then: 144%

D-Wave Quantum Inc. (NYSE:QBTS) is a quantum computing hardware and software company. The firm has been busy this year as it has made several important announcements. One of these came in May after D-Wave Quantum Inc. (NYSE:QBTS)  announced the availability of its Advantage2 quantum computing system. Over the year the firm’s shares have gained a whopping 1,454%, and they jumped by a respectable 26% the day it announced its new quantum computing computers. Cramer’s recent remarks about D-Wave Quantum Inc. (NYSE:QBTS) have quoted the firm’s management as saying that they could crack cryptocurrency if their quantum computers were on track. However, in December 2024, Cramer was quite cautious about D-Wave Quantum Inc. (NYSE:QBTS):

“these companies, can I just say, when you have GE Vernova saying listen I love to do nuke but I can’t. And they are the biggest nuke company in the world. How are these companies going to, how is DWave Quantum by the way, how is that going to quantum? When we don’t even know what quantum is? It’s a nonfungible tokens, right? Cause you know what a fungible token was?”

Compare these remarks with Cramer’s latest thoughts about D-Wave Quantum Inc. (NYSE:QBTS):

“D-Wave, I just, we are on Mad Money, putting every single one on, why? Because that’s what the public wants and we have to stop snubbing.

“Now I had D-Wave on last night, a quantum company. And I’ve got to tell you, they are saying if we get our, if we get where we are, this could all come down. That crypto could be in trouble if quantum comes out because they can overrun the blockchain.”

12. Quantum Computing Inc. (NASDAQ:QUBT)

Number of Hedge Fund Holders In Q2 2025: 11

Date Of Cramer’s Remarks: 1/2/25

Share Price Performance Since Then: -15.6%

Quantum Computing Inc. (NASDAQ:QUBT) is a quantum computing hardware company that is developing an entropy quantum computer. It is one of the riskier quantum computing plays since it has yet to generate a profit and is incurring hefty operating expenses. As an illustration, during the calendar year 2024, Quantum Computing Inc. (NASDAQ:QUBT) generated $373,000 in revenue but incurred $26 million in operating expenses. Looking at its finances, it’s no wonder that Cramer believes that quantum computing is a long-term play. Quantum Computing Inc. (NASDAQ:QUBT)’s shares have lost 15.6% since Cramer made these remarks, with a major selloff occurring after NVIDIA CEO Jensen Huang shared that he believed quantum computing couldn’t deliver quick gains:

“I’m also concerned about a company called Quantum Computing, $2.4 billion, with $400,000 in revenues in the last 12 months and again, very big losses.”

The CNBC TV host maintained his skepticism about Quantum Computing Inc. (NASDAQ:QUBT) in his latest remarks as well:

“It’s not so much as it’s too late. It’s a money-losing company, and if we get rid of the fervor for the moment about quantum, you’ll be buying that $17 stock at $7, and that’s what I worry about the most.”

11. Alphabet Inc. (NASDAQ:GOOGL)

Number of Hedge Fund Holders In Q2 2025: 219

Date Of Cramer’s Remarks: 1/2/25

Share Price Performance Since Then: 8.8%

Alphabet Inc. (NASDAQ:GOOGL) is one of Jim Cramer’s top quantum computing plays. The CNBC TV host prefers the firm due to its resources, which can allow it to scale up its quantum computing business. Alphabet Inc. (NASDAQ:GOOGL) made quite a splash in December 2024 when it announced that its Willow quantum computing chip was capable of beating the world’s fastest supercomputers. Here is what Cramer said about Alphabet Inc. (NASDAQ:GOOGL) and quantum computing in January:

“Alphabet has a facility dedicated to quantum computing. This is super fast computing using superconductors that require a specialized computer environment based in part on cryogenic technology. Sounds promising, the others burn too hot, right, the regular data centers. But it’s not a reason to buy Alphabet because it’s nothing that’s ready at scale. I like Alphabet, own it for the Charitable Trust, but that’s because we like their dominance in Search, progress in YouTube, and incredible strength of Google Cloud services, well ahead of what people think. Quantum computing is just a long-term project.”

Cramer hasn’t changed his mind about Alphabet Inc. (NASDAQ:GOOGL)’s quantum computing prospects as the year has passed, as is clear through his latest comments:

“[When he wondered how many years away are we from scaled quantum and which stocks might be worth it] Well you know then the question is [inaudible] you really want to go after, it’s Google and it’s IBM.”

10. Rigetti Computing, Inc. (NASDAQ:RGTI)

Number of Hedge Fund Holders In Q2 2025: 17

Date Of Cramer’s Remarks: 1/8/25

Share Price Performance Since Then: 47.6%

Rigetti Computing, Inc. (NASDAQ:RGTI) makes and sells quantum processors and computing systems. Since Cramer commented on the firm, its shares have gained 47.61%. The day Cramer commented on Rigetti Computing, Inc. (NASDAQ:RGTI) was quite important for quantum stocks, as it was the day after NVIDIA CEO Jensen Huang commented that he believed quantum computing’s practical purposes were at least 20 years away. During the day of Cramer’s remarks, Rigetti Computing, Inc. (NASDAQ:RGTI)’s shares sank by a whopping 45.4%, so naturally, the shares have gained since then. Here’s what Cramer said in January:

“So what you have is a stock like Rigetti. You’ll see that under the crawl just this very moment. RGTI. Now this is a two-dollar stock from a few months ago. And they did a gigantic [inaudible], fifty million share offering at two dollars eleven cents, really basically because they needed the money. They had flat revenues for a long time.

“I would argue that Rigetti, which also had a lot of insider selling is probably the worst one. It’s up a great deal. They needed the money just back in November. I think people took it up and they have no idea what it really does. It designs quantum computers and superconducting quantum computing processors and that’s precisely what Jensen Huang is saying is really not that valuable.”

9. Microsoft Corporation (NASDAQ:MSFT)

Number of Hedge Fund Holders In Q2 2025: 294

Date Of Cramer’s Remarks: 1/15/25

Share Price Performance Since Then: 19%

Microsoft Corporation (NASDAQ:MSFT), the world’s largest technology company, has gained 19% since Cramer commented on the firm in the context of quantum computing. Most of the stock’s gains are not due to quantum computing. Instead, Microsoft Corporation (NASDAQ:MSFT) has performed modestly well so far, as investors believe that the firm’s Azure cloud computing business is growing adequately to justify its multi-billion-dollar artificial intelligence investments. Here’s what Cramer said about Microsoft Corporation (NASDAQ:MSFT) and quantum computing:

“[A MSFT blog about quantum] I love the people at Microsoft. But the idea that this is quantum’s hour, they’re the only, well it’s easy to say it [inaudible], the problem is, is it commercial? And there isn’t anyone who thinks that the companies that are currently trading are commercial companies.”

Cramer’s recent comments about Microsoft Corporation (NASDAQ:MSFT) have commented on its Azure cloud business:

“Azure, I think it might even be four, five percent. Meaning 39 get knocked back to [34, 35% growth]. Yeah so then Amazon doesn’t look as stupid and horrible as everybody says with Amazon Web Services falling behind. A lot of companies do write, younger companies want want to write on chat [ChatGPT], they want to write on OpenAI.”

8. IonQ, Inc. (NYSE:IONQ)

Number of Hedge Fund Holders In Q2 2025: 30

Date Of Cramer’s Remarks: 5/27/25

Share Price Performance Since Then: -17%

IonQ, Inc. (NYSE:IONQ) is a quantum computing company that enables businesses to access quantum computing through cloud platforms such as Amazon’s AWS. Since Cramer’s comments, the shares have lost 17%. However, on the day he commented on IonQ, Inc. (NYSE:IONQ), the stock had gained 43% since the 21st. The stock rose as peer D-Wave announced its new quantum computers, which turned out to be a bullish catalyst for the industry. While Cramer has recently started to change his beliefs on quantum, here’s what he said about IonQ, Inc. (NYSE:IONQ) in May 2025:

“Oh my god, it’s so high and it’s losing so much money, but it’s quantum. If I offer you a considered explanation of why I think that stock’s too expensive, most people ignore it, so all I’m going to say is it’s too speculative for me. I don’t know what else to say.”

Compare these remarks with the CNBC TV host’s latest comments about IonQ, Inc. (NYSE:IONQ):

“My first quantum company. I’m going all in on what youth wants. They inherit the earth, I have the heart of darkness. I’m trying to get away from that. When Jensen switched and said he’s in on quantum, who am I to say, that the man who the President thought about breaking up the company but said it was too great, I’m going all in quantum.”

7. NANO Nuclear Energy Inc. (NASDAQ:NNE)

Number of Hedge Fund Holders In Q2 2025: 3

Date Of Cramer’s Remarks: 10/01/2024

Share Price Performance Since Then: 89%

NANO Nuclear Energy Inc. (NASDAQ:NNE) is a new-age nuclear technology company developing solid-core battery reactors. Its products make the firm one of the most speculative nuclear power stocks. NANO Nuclear Energy Inc. (NASDAQ:NNE)’s shares have gained 31% year-to-date and 89% since Cramer commented on the firm in October. One major catalyst for the stock came in May after President Trump signed an executive order to boost the small nuclear reactor industry in the US. Cramer commented on the firm’s financials, and his worries aren’t unwarranted as NANO Nuclear Energy Inc. (NASDAQ:NNE) posted a net loss of $10.1 million during its fiscal year ending in September 2024 on the back of no revenue:

“I am aware of it. Let’s just be honest… That company loses a lot of money”

Cramer’s more recent comments about NANO Nuclear Energy Inc. (NASDAQ:NNE) have advised viewers to sell the stock:

“I think you just sell Nano Energy. I think the first time we’ll see any nuclear… in this country is 2033 and that’ll be done by GE Vernova if it’s lucky.”

6. Vistra Corp. (NYSE:VST)

Number of Hedge Fund Holders In Q2 2025: 111

Date Of Cramer’s Remarks: 10/10/2024

Share Price Performance Since Then: 53.5%

Vistra Corp. (NYSE:VST) is s sizable American utility whose power generation portfolio also includes nuclear power. Since Cramer commented on the firm in October 2024, the shares have gained 53.5%. Cramer has continued to discuss Vistra Corp. (NYSE:VST) in 2025, and most of his remarks have revolved around the firm’s exposure to the data center industry. Some catalysts that have driven the stock include a strong first-quarter earnings report and an acquisition to diversify its natural gas power generation portfolio. Here’s what Cramer said about Vistra Corp. (NYSE:VST) in October 2024:

“Third is a company we’ve been talking increasingly about this year. It’s called Vistra and this one’s about the data center too. Vistra’s one of the largest independent power producers. Nuclear capacity, which means reliable carbon-free energy. Data centers are voracious consumers of energy and the companies that use them can’t get enough of. Now. I personally think the stock’s a little overdone given its 479% move, but the next time it has one of its monster pullbacks, which do occur, I would do some buying.”

5. NuScale Power Corporation (NYSE:SMR) 

Number of Hedge Fund Holders In Q2 2025: 30

Date Of Cramer’s Remarks: 10-18-24/10-21-24

Share Price Performance Since Then: 192%

NuScale Power Corporation (NYSE:SMR) is a nuclear power generation hardware manufacturer that primarily deals with small and modular nuclear reactors. Its shares have gained 97.8% year-to-date, but would have been even higher had it not been for a 32% dip since late-July. The stock has gained a whopping 192% since Cramer’s October comments, where he warned that the firm was losing a lot of money and it was better to invest in GE Vernova instead. Some catalysts that have driven NuScale Power Corporation (NYSE:SMR)’s performance since July include a weak earnings report and a shareholder selling the stock. Here’s what Cramer said about the firm in October 2024:

“Yes, again, that’s a small scale nuclear module reactor [company]. And I think that company’s losing a lot of money. You might as well go again with GE Vernova, GEV, because that’s something else to fall back on and you still get the nukes.”

Cramer continues to believe that NuScale Power Corporation (NYSE:SMR) is overvalued, as he recently commented:

“NuScale, okay, here’s the problem with NuScale, it is… really, really high. Here’s the answer with NuScale, if it does an offering here, that’s when I’d buy. I’d wait for the stock offering after what happened with Oklo tonight.”

4. Oklo Inc. (NYSE:OKLO)

Number of Hedge Fund Holders In Q2 2025: 36

Date Of Cramer’s Remarks: 2/24/25

Share Price Performance Since Then: 106%

Oklo Inc. (NYSE:OKLO) is a popular nuclear energy stock among retail investors. The firm develops nuclear power plants, and its shares have gained a whopping 222% year-to-date. Since Cramer’s comments in February, Oklo Inc. (NYSE:OKLO)’s stock has gained 106%. One recent catalyst for the firm was its second-quarter earnings, which sent the stock jumping by 9.2%. The shares rose after Oklo Inc. (NYSE:OKLO) announced that it had completed the first phase of a nuclear regulatory assessment. Here is what Cramer said about the firm in February:

“We really don’t need the, if we don’t want them, you know. I’ll tell you what we really don’t need, we don’t need the nuclear fission through Oklo. A total fan favorite. That’s one of the most speculative stocks out there… It’s frightening when you own a stock because of quantum computing prospects and then those hopes are dashed by an authoritative expert.”

The CNBC TV host hadn’t shifted his opinion on Oklo Inc. (NYSE:OKLO) as late as June when he commented:

“Now, Oklo has no earnings and it’s losing… money, but no matter. After the close tonight, the company offered $400 million worth of stock to give them plenty of breathing room. It’s the kind of smart offering that keeps the ball rolling.

Others here should be thinking of the same thing when they have good news, like Oklo. The income statements simply don’t matter in the year of magical thinking because we just learned that Oklo was selected as the intended award winner to power Eielson Air Force Base in Alaska with a nuclear power plant. When it rains, it pours. The NRC, the Nuclear Regulatory Commission, has started reviewing a report that says Oklo could streamline the whole process, which we know is cumbersome… Maybe these guys can build, make it easier to build nukes. I don’t know. Oklo has the whole group jumping, which is exactly what you’d expect in this year of magical thinking.”

3. BWX Technologies, Inc. (NYSE:BWXT)

Number of Hedge Fund Holders In Q2 2025: 52

Date Of Cramer’s Remarks: 2/27/25

Share Price Performance Since Then: 59.7%

BWX Technologies, Inc. (NYSE:BWXT) is a diversified nuclear power generation hardware manufacturer that makes and sells equipment such as nuclear reactors. Its shares have gained 46% year-to-date, primarily on the back of a major 17.8% gain in early August. The shares rose after BWX Technologies, Inc. (NYSE:BWXT)’s second quarter earnings report saw $1.02 in EPS beat analyst estimates of $0.79 and $764 million in revenue beat estimates of $708.6 million. Investors were also impressed by the fact that BWX Technologies, Inc. (NYSE:BWXT) raised its revenue guidance. Here is what Cramer said about the firm in February:

“That’s nuclear. You know, look, the bloom is off the rose. Nuclear, it was never really there. We don’t have any sort of initiative that really makes nuclear the right thing. Small modular nuclear power’s still not happening. It’s going to be 2033 before we see anything new in nuclear and that is just too far for me. But I’m telling the truth now. I mean, I’m, I’m done with it. I, I don’t wanna hear about it anymore.”

More recently, Cramer was rather sarcastic about BWX Technologies, Inc. (NYSE:BWXT):

“Alright, that’s nuclear. And again, like you know, nuclear, I’m not going to fight anyone who wants to enter a nuclear stock. I’m going to bless it even though it’s up very, very big.”

2. GE Vernova Inc. (NYSE:GEV)

Number of Hedge Fund Holders In Q2 2025: 106

Date Of Cramer’s Remarks: 2/20/25

Share Price Performance Since Then: 69%

GE Vernova Inc. (NYSE:GEV) is one of Cramer’s top nuclear stock picks. The firm makes and sells nuclear reactors, and Cramer is optimistic about its ability to deliver the equipment. Since his comments in February, GE Vernova Inc. (NYSE:GEV)’s shares have gained 69%. One notable catalyst came in July after the shares jumped by 13.7%. The jump came after the firm’s $9.1 billion in revenue and $1.86 in profit-per-share beat analyst estimates of $8.8 billion and profit estimates of $1.50. Seems like Cramer’s enthusiasm about GE Vernova Inc. (NYSE:GEV) was warranted:

“We’re going to talk about the stock of GE Vernova. That’s the power division that was spun off from the old General Electric that so many of you like. Right now, we’ve got several huge themes occurring at once. We know that we have a gigantic number of data centers being put up in the country, correct? Now they require tremendous amount of electricity. They’re big drainers. Our most abundant source of power comes from burning of natural gas. We got more natural gas than any other country.

“GE Vernova makes the turbines. Those are huge machines, up to 700,000 pounds, that burn the natural gas, which then generates electricity. Now there’s the theme for you, but that’s not all. Today, the Tennessee Valley Authority, remember them, announced that it’s going to submit a construction permit for a small modular nuclear reactor, again because we need more power for the data centers. Who makes those? GE Vernova. And we know that the Empire offshore wind project off the coast of New York just got re-greenlighted by the Trump administration. According to a 2022 press release, GE Vernova will be responsible for designing and building the high-voltage electrical system connected to this. It’s a huge multi-year project that will be fantastic for, yes, GE Vernova.

Oh, and if you are a country with a trade surplus with the US, the best way to get it down and then you lose the ire of the president, get away or get rid of the wrath, well, it’s always been to buy a Boeing plane, but I don’t think that works as much anymore. You know what you gotta do? You gotta buy a turbine from GE Vernova. It takes a lot to buck the bond voters. But GE Vernova has not one, not two, not three, but four secular trends going for it. That’s what you need. That’s belt, suspenders, and suspenders and then belt again.”

1. Centrus Energy Corp. (NYSE:LEU)

Number of Hedge Fund Holders In Q2 2025: 27

Date Of Cramer’s Remarks: 2/27/25

Share Price Performance Since Then: 108%

Centrus Energy Corp. (NYSE:LEU) is a uranium provider. Its shares have gained 151% year-to-date and are up by 108% since Cramer’s comments in February. One notable jump came in May when the stock rose by 37% over the course of several days. Driving this jump was President Trump’s executive order, which aimed to streamline the development of the nuclear power industry and unlock additional demand for Centrus Energy Corp. (NYSE:LEU)’s products. Here is what Cramer had said about the firm in February:

“What a horse. Okay, nuclear power… people just believe nuclear power, no matter what. Now, I think that’s fine, but I suggest that you calm down and you buy GE Vernova, which has been such an up stock and also has nat gas.”

Cramer wasn’t a fan of Centrus Energy Corp. (NYSE:LEU) in July as he commented:

“Okay, and I know the company. Centrus Energy fits in this particular niche that I’ve been saying, along with Oklo. I am not going to go against anybody who wants to buy uranium or nuclear because it’s coming back. Do I think it’s going to come back within the time frame… That’s no longer necessary. We have a new kind of market. I believe… when you get the book that comes out at the end of September, How to Make Money in Any Market, you will see that I endorse having one speculative position in your portfolio. Make Centrus your speculative position, and I say you are on my team. You will make money in any market.”

While we acknowledge the potential of LEU to grow, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and have limited downside risk. If you are looking for an AI stock that is more promising than LEU and that has 100x upside potential, check out our report about this cheapest AI stock.
