While quantum computing stocks had quite a ride last year, CNBC’s Jim Cramer continued to advise caution when considering buying. However, while he primarily discussed individual stocks, the performance of exchange-traded funds (ETFs) is mostly in the green. Out of the VanEck Quantum Computing UCITS ETF, Defiance Quantum ETF, and WisdomTree Quantum Computing Fund, only the WisdomTree fund is down by 14% over the past year. The other two, on the other hand, are up by 21.8% and 38.9%, respectively. Advising viewers to “get the money and then you blow out of the stocks,” in late October, the CNBC TV host discussed some quantum computing stocks. “Get the money and blow out. Because the losses are overwhelming,” he added and outlined that competing with IBM and Alphabet was akin to bringing a “knife to a nuclear war fight.”

Our Methodology

To make our list of Jim Cramer’s quantum and data center stock hits we made a list of AI stocks that he was optimistic about in 2025. Then, their performance since the comments were made was calculated, and the stocks were ranked accordingly. Additionally, the number of hedge fund investors back then was also mentioned. Finally, the number of investors as of the third quarter of 2025 was also mentioned for additional context.

For instance, the shares fell by 48% in January after Cramer’s comments due to investor reaction to NVIDIA CEO Jensen Huang’s comments about the quantum computing industry at the CES conference, Huang, widely considered to be one of the top authorities in the computer industry, had commented that he believed useful quantum computers were as much as 30 years in the future. Then, the stock closed 11.7% lower on March 20th after the firm reported its Q4 2024 earnings. However, Quantum Computing, Inc.

In his Mad Money appearance on January 2nd, Cramer remarked that he was concerned about the firm:

Like other quantum computing stocks, IonQ, Inc. (NYSE:IONQ) also suffered a hefty blow in January after NVIDIA CEO Jensen Huang remarked that quantum computing systems were quite far out in the future. However, between March 7th to September 19th, the stock surged by 242%. During the time period, several notable events occurred. For instance, IonQ, Inc. (NYSE:IONQ)’s shares closed a whopping 36% higher on May 22nd after its CEO sat for an interview with Barron’s magazine and remarked that his firm plans to become the NVIDIA of the quantum computing industry. However, since their peak on October 13th, the shares are down by 59%. Amidst the gains and losses, Cramer warned that IonQ, Inc. (NYSE:IONQ) was too expensive in April:

“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.”

9. Rigetti Computing Inc. (NASDAQ:RGTI)

Number of Hedge Fund Holdings in Q3 2024: 7

Number of Hedge Fund Holdings in Q4 2025: 26

However, between January 10th and October 17th, Rigetti Computing Inc. (NASDAQ:RGTI)’s stock surged by a massive 419%. Several factors drove the meteoric surge in price. For instance, the firm announced on September 30th that it had received purchase orders for two Novera quantum computers. The announcement came after Rigetti Computing Inc. (NASDAQ:RGTI) had announced in August that it had made its 36-qubit system, Cepheus-1-36Q, available on its cloud platform. However, the stock has been on a downward trend since November, and here is what Cramer had said in his Mad Money appearance:

“But then for example, when I look at Rigetti Computing, it’s a $5.6 billion company, professes to be a leader in quantum computers and superconducting equipment, I grow concerned. Rigetti is a multiple-year money loser with just $11.9 million in revenues in the last 12 months.

This stock was at 66 cents four months ago. Now it’s at 20 bucks, up over 30% just today. Its big break occurred at the end of November when it sold 50 million shares at two bucks. The stock was off the races ever since then. Hey, it’s a quantum GameStop, okay?”

7. International Business Machines Corporation (NYSE:IBM)

Number of Hedge Fund Holdings in Q1 2025: 57

Date/Month of Cramer’s Remarks: August 13th, 2025

International Business Machines Corporation (NYSE:IBM) is one of the largest enterprise computing companies in the world. While Cramer is also a fan of its enterprise business, the firm is one of two quantum computing stocks that the CNBC TV host has regularly spoken in favor of.

Over the year, the shares are up by 2.7%, and since Cramer’s comments on Mad Money, they are up by 8.5%. However, February 2026 was a tough month for International Business Machines Corporation (NYSE:IBM) as the shares lost 25% between February 6th and February 23rd. In what is widely described as one of the worst selloffs in the company’s history, the stock tumbled after investors worried about the disruptive potential of Anthropic’s Claude AI, as per media reports. The selloff came roughly six months after Cramer advocated buying International Business Machines Corporation (NYSE:IBM) due to strong fundamentals:

“Okay, I didn’t think IBM’s quarter… was all that bad at all. I think you have a major opportunity down here because I think that we’re going to start talking about IBM and quantum. I think they have the lead in quantum, and I think quantum really does matter. They have a great software package. They’re doing so many things that are good.

Against that, let me tell you what’s really going on. The chart’s bad, and people are saying it’s a head and shoulders. Now, you and I both know there comes a time when you have to step in if the fundamentals are right, and I think we’re there, okay.”

6. Arista Networks, Inc. (NYSE:ANET)

The shares, like other AI and data center stocks, struggled in November during a period characterized by uncertainty about AI stocks, according to media reports. Cramer was optimistic about Arista Networks, Inc. (NYSE:ANET) as early as January 2025:

“Then Arista, well you know Arista’s the one a lot of people feel, that’s Jayshree Ullal, Jayshree, that’s the plumbing for data centers. So that makes a lot of sense. Jayshree is a very compelling figure in terms of, even more than Broadcom, in the data center.”
