Just as the internet transformed society, quantum computers hold a similar promise. These groundbreaking machines harness quantum physics to perform complex calculations in minutes that would take today's supercomputers centuries.
However, today's quantum computers are error-prone and difficult to scale. The first businesses to construct devices capable of widespread use could revolutionize whole industries. For that reason, quantum computer companies D-Wave Quantum (NYSE: QBTS) and IonQ (NYSE: IONQ) present intriguing investment opportunities.
But is D-Wave or IonQ the superior investment in this nascent sector? An examination of both can help you arrive at an answer.
D-Wave shares have made an impressive run in 2025. The stock is up over 90% this year, hitting a 52-week high of $19.77 in May. Its shares took off because of a massive 509% year-over-year jump in first-quarter revenue, hitting $15 million. To put that in perspective, the Q1 sum alone was far more than D-Wave's total sales of $8.8 million for all of 2024.
The stupendous revenue growth was due to D-Wave's first sale of its proprietary Advantage quantum machine. In years past, the bulk of its revenue came from selling quantum computing as a service (QCaaS), in which customers pay a fee for remote access to the company's quantum capabilities through the cloud.
Thanks to its exceptional revenue, D-Wave's Q1 operating loss improved to $11.3 million from $17.5 million in 2024. The company also boasted a solid balance sheet. First-quarter total assets were $325.6 million with a whopping $304.3 million of that in cash. First-quarter liabilities totaled $118.2 million.
D-Wave management stated that its Q1 cash balance is sufficient to sustain the business until it becomes profitable. Since then, the company further boosted its cash reserves to approximately $815 million through an equity offering. Some of the funds are earmarked for acquisitions.
IonQ's 2025 stock performance has been more muted than D-Wave's. Its shares are up 9% through July 9. A contributing factor is IonQ's lackluster Q1 results.
Revenue reached $7.6 million, which was flat compared to 2024. Worse, while revenue failed to grow, expenses certainly did. The company's Q1 operating loss of $75.7 million was a significant increase over the prior year's loss of $52.9 million.
That said, the company has a strong balance sheet. Total Q1 assets were $850.1 million versus total liabilities of just $85 million. On top of that, IonQ announced a $1 billion equity offering on July 7, which should further shore up its finances. IonQ has been on a tear acquiring businesses over the past year as it attempts to build a quantum computing network.
Considering the internet exists because of computer networking, IonQ's approach could be a game changer. But the strategy is expensive, since it must assemble many capabilities to make a viable quantum network. For instance, these networks cannot extend far today, so IonQ acquired Lightsynq Technologies, which is working on tech to expand the range quantum devices can be networked.
While IonQ seeks to build a quantum network, D-Wave claims to be the sole provider of both the prevailing quantum gate technology and quantum annealing, a technique for finding optimal solutions among numerous possibilities.
It's too early to tell whether IonQ or D-Wave's approach will win out over the long run, and that's the challenge in choosing between these two. Either company could become a leader in the field, or it could be a much larger competitor, such as Microsoft, which has developed its own quantum technology called topological qubits.
In addition, D-Wave's sizable Q1 result may be a feat that it won't repeat anytime soon. Its sale of an Advantage system is a departure from the usual QCaaS and professional services revenue, which provided nearly all its income over the past two years.
As for IonQ, it may have experienced an underwhelming Q1, but it exited 2024 with 95% year-over-year revenue growth to $43.1 million. It also expects 2025 sales to reach between $75 million and $95 million, which would represent a substantial jump up from 2024.
Another consideration is the share price valuation of these companies, which can be assessed with the price-to-sales (P/S) ratio. The chart below shows that the P/S multiples for D-Wave and IonQ are not only higher than a year ago, but considerably greater than Microsoft's. This suggests shares of D-Wave and IonQ are overpriced.
Considering their sky-high valuations and the uncertainty surrounding which quantum computing technology will eventually dominate, the optimal strategy is to wait for Q2 earnings before deciding to buy shares in either company. This lets you see whether D-Wave's Q1 results are a one-off, and if IonQ can bounce back from tepid Q1 sales to achieve its projected year-over-year growth for 2025.

Cahya Mata Sarawak Berhad's (KLSE:CMSB) top owners are retail investors with 39% stake, while 22% is held by institutions
Cahya Mata Sarawak Berhad's significant retail investors ownership suggests that the key decisions are influenced by shareholders from the larger public 50% of the business is held by the top 9 shareholders Insider ownership in Cahya Mata Sarawak Berhad is 20% This technology could replace computers: discover the 20 stocks are working to make quantum computing a reality. Every investor in Cahya Mata Sarawak Berhad (KLSE:CMSB) should be aware of the most powerful shareholder groups. And the group that holds the biggest piece of the pie are retail investors with 39% ownership. That is, the group stands to benefit the most if the stock rises (or lose the most if there is a downturn). Institutions, on the other hand, account for 22% of the company's stockholders. Large companies usually have institutions as shareholders, and we usually see insiders owning shares in smaller companies. Let's delve deeper into each type of owner of Cahya Mata Sarawak Berhad, beginning with the chart below. View our latest analysis for Cahya Mata Sarawak Berhad Many institutions measure their performance against an index that approximates the local market. So they usually pay more attention to companies that are included in major indices. We can see that Cahya Mata Sarawak Berhad does have institutional investors; and they hold a good portion of the company's stock. This suggests some credibility amongst professional investors. But we can't rely on that fact alone since institutions make bad investments sometimes, just like everyone does. When multiple institutions own a stock, there's always a risk that they are in a 'crowded trade'. When such a trade goes wrong, multiple parties may compete to sell stock fast. This risk is higher in a company without a history of growth. You can see Cahya Mata Sarawak Berhad's historic earnings and revenue below, but keep in mind there's always more to the story. Hedge funds don't have many shares in Cahya Mata Sarawak Berhad. Majaharta Sdn Bhd is currently the company's largest shareholder with 13% of shares outstanding. Meanwhile, the second and third largest shareholders, hold 11% and 6.8%, of the shares outstanding, respectively. On further inspection, we found that more than half the company's shares are owned by the top 9 shareholders, suggesting that the interests of the larger shareholders are balanced out to an extent by the smaller ones. While studying institutional ownership for a company can add value to your research, it is also a good practice to research analyst recommendations to get a deeper understand of a stock's expected performance. While there is some analyst coverage, the company is probably not widely covered. So it could gain more attention, down the track. While the precise definition of an insider can be subjective, almost everyone considers board members to be insiders. The company management answer to the board and the latter should represent the interests of shareholders. Notably, sometimes top-level managers are on the board themselves. Insider ownership is positive when it signals leadership are thinking like the true owners of the company. However, high insider ownership can also give immense power to a small group within the company. This can be negative in some circumstances. Our most recent data indicates that insiders own a reasonable proportion of Cahya Mata Sarawak Berhad. It has a market capitalization of just RM1.3b, and insiders have RM270m worth of shares in their own names. We would say this shows alignment with shareholders, but it is worth noting that the company is still quite small; some insiders may have founded the business. You can click here to see if those insiders have been buying or selling. With a 39% ownership, the general public, mostly comprising of individual investors, have some degree of sway over Cahya Mata Sarawak Berhad. This size of ownership, while considerable, may not be enough to change company policy if the decision is not in sync with other large shareholders. Our data indicates that Private Companies hold 18%, of the company's shares. Private companies may be related parties. Sometimes insiders have an interest in a public company through a holding in a private company, rather than in their own capacity as an individual. While it's hard to draw any broad stroke conclusions, it is worth noting as an area for further research. It's always worth thinking about the different groups who own shares in a company.

Trump says Mexico, EU to face 30% tariff from Aug 1
President Donald Trump on Saturday targeted Mexico and the European Union with steep 30 percent tariffs, dramatically raising the stakes in already tense negotiations with two of the largest US trading partners. Both sets of duties would take effect August 1, Trump said in formal letters posted to his Truth Social platform. The president cited Mexico's role in illicit drugs flowing into the United States and a trade imbalance with the EU as meriting the tariff threat. Both partners swiftly slammed the new duties, with the EU warning they could disrupt supply chains -- but insisting it would continue talks seeking an agreement with the US -- while Mexico branded them an "unfair deal." French President Emmanuel Macron expressed "very strong disapproval" of the step and called on the bloc to "resolutely defend European interests." Since returning to the presidency in January, Trump has unleashed sweeping stop-start tariffs on allies and competitors alike, roiling financial markets and raising fears of a global economic downturn. But his administration is coming under pressure to secure deals with trading partners after promising a flurry of agreements. So far, US officials have only unveiled two pacts, with Britain and Vietnam, alongside temporarily lower tit-for-tat duties with China. - 'Not enough' - The fresh duties for Mexico announced by Trump would be higher than the 25 percent levy he imposed on Mexican goods earlier this year, although products entering the United States under the US-Mexico-Canada Agreement (USMCA) are exempted. "Mexico has been helping me secure the border, BUT, what Mexico has done, is not enough," Trump said in his letter to Mexican President Claudia Sheinbaum. "Starting August 1, 2025, we will charge Mexico a Tariff of 30% on Mexican products sent into the United States." The Mexican government said it had been informed of the new threat during talks in the United States on Friday. "We mentioned at the table that it was an unfair deal and that we did not agree," the Mexican economy and foreign ministries said in a joint statement. The EU tariff is also markedly steeper than the 20 percent levy Trump unveiled in April, as negotiations with the bloc continue. "Imposing 30 percent tariffs on EU exports would disrupt essential transatlantic supply chains, to the detriment of businesses, consumers and patients on both sides of the Atlantic," European Commission chief Ursula von der Leyen said in a statement, in reply to Trump's letter to her. "We remain ready to continue working towards an agreement by August 1. At the same time, we will take all necessary steps to safeguard EU interests, including the adoption of proportionate countermeasures if required," she added. Meanwhile Macron backed efforts to reach an agreement that "reflects the respect that trade partners such as the European Union and the United States owe each other." But he urged the bloc to "step up the preparation of credible countermeasures" to implement if the two sides fail to reach an agreement in time. - Precarious moment - The EU, alongside dozens of other economies, had been set to see its US tariff level increase from a baseline of 10 percent on Wednesday, but Trump pushed back the deadline to August 1. Mexico and Canada come under a separate tariff regime. Since the start of the week, Trump has sent out letters to more than 20 countries with updated tariffs for each, including a 35 percent levy for Canada. A US official told AFP Saturday that the USMCA exemption was expected to remain for both Mexico and Canada, although the president has yet to make final decisions. Brussels said Friday that it was ready to strike a deal with Washington to prevent the return of 20 percent levies. The EU has prepared retaliatory duties on US goods worth around 21 billion euros after Trump also slapped separate tariffs on steel and aluminum imports earlier this year, and they are suspended until July 14. European officials have not made any move to extend the suspension but could do it quickly if needed. "Despite all the movement toward a deal, this threat shows the EU is in the same camp of uncertainty as almost every other country in the world," said Josh Lipsky, chair of international economics at the Atlantic Council. He told AFP that the path forward now depends on how the EU responds, calling it "one of the most precarious moments of the trade war so far." bys-st/md/aks Error in retrieving data Sign in to access your portfolio Error in retrieving data Error in retrieving data Error in retrieving data Error in retrieving data

The ‘Cable Cowboy' Battles a Giant Gas Station for the Soul of the West
PALMER LAKE, Colo.—Trina Shook took to the podium during a town hall meeting here in May to denounce a plan to locate a Buc-ee's, a colossal roadside rest stop, on the outskirts of the tiny town. 'I'm disgusted by you personally, and by the company,' Shook informed the mayor in the packed meeting room, while an overflow crowd listened outside, shivering in the rain.
