3 Millionaire-Maker Technology Stocks
If quantum computing takes off in the next decade, IonQ could be a big winner.
SoundHound is a company that has shown its ability to adapt, and it could become a big winner in agentic AI.
Palantir has the potential to become one of the largest AI companies in the world.
10 stocks we like better than IonQ ›
If you're looking to invest in potential millionaire-making tech stocks, you're sometimes going to have to swing for the fences. The three stocks below are bold bets on companies chasing massive markets with long runways. You're not buying these stocks looking for modest returns; you're buying them because you see a shot at something transformational.
That said, these are high-risk, high-potential-reward stocks. None of their valuations are cheap, and most are still just starting to scratch the surface of their potential. But if the technologies deliver and management teams execute, the upside could be enormous.
IonQ
Quantum computing company IonQ (NYSE: IONQ) isn't just an academic lab with a bunch of theoretical physics testing hypotheses, like the characters on the TV show "The Big Bang Theory." It's building real quantum computers that are already being tested in commercial, government, and academic settings. IonQ is working to build fault-tolerant systems that can operate at scale, which is the holy grail in quantum computing. Without that reliability, this emerging technology won't move beyond the lab.
The company has made solid early progress. It's working with AstraZeneca, Amazon, and Nvidia on early use cases, and it has a strong balance sheet with around $700 million in cash and investments and zero debt. That gives it time and room to invest without constantly going to the market for funding.
IonQ also opened a 65,000 square foot facility in Washington to manufacture systems in-house. That's another sign that this isn't just a science project anymore and that the company is gearing up to deliver working machines.
The company has also been acquiring smaller quantum computing players to help bolster its capabilities. That's a smart move in a burgeoning field where technical talent and intellectual property are key.
There's still a long road ahead, but if quantum computing takes off in the next decade, IonQ is positioned to be one of the companies that could be a huge winner.
SoundHound AI
While SoundHound AI (NASDAQ: SOUN) is still a relatively young company, it has consistently been able to adapt in an ever-evolving tech landscape. That's something great tech companies do.
A leader in "speech-to-meaning" and "deep meaning understanding" technology, the company acquired Amelia last year to add its advanced conversational intelligence to its platform. It's now taking this combined technology and applying it to create voice-first artificial intelligence (AI) agents that can go out and complete tasks without the need for human intervention.
By merging its voice technology with Amelia's enterprise software, SoundHound now has a complete voice automation platform. SoundHound has been strong in the automobile and restaurant industries, while Amelia brought with it expertise in the medical and financial verticals, which have their own nuances and specific industry jargon. It's also used Amelia's technology as part of the foundation for its AI agent ambitions. With the recent rollout of its Amelia 7.0 platform, it's now moved beyond being simply an AI voice company to being a voice-first agentic AI company.
This is still a small company with something to prove, but the product roadmap and customer traction suggest it's heading in the right direction. And as I said at the beginning, it has been quick to adapt. The company actually started out as a platform for discovering music, where it would then direct customers to online music stores. It's come a long way since those early days, and the future looks bright.
Palantir
Palantir Technologies (NASDAQ: PLTR) is the largest company on this list and the one with the clearest momentum. Originally formed to help fight terrorism after 9/11, the data gathering and analytics company has been a key government vendor for years. However, it has successfully expanded into the commercial sector, where its AI platform (AIP) has become a central tool for helping organizations implement AI in the real world.
Most businesses don't lack data -- they lack the tools to do anything meaningful with it. Palantir helps organizations gather data from a wide variety of sources and then structure it into an ontology that links the data to their real-world counterparts. The ontology provides clean, structured data that helps AI models operate more effectively. Customers can then apply whatever AI models they want with this ontology to identify real-world problems and then go out and solve them.
AIP has been a hit with commercial customers. In Q1, its U.S. commercial revenue grew 71%, and commercial deal value more than doubled. Best of all, most of these deals are in their early stages, and Palantir has a big opportunity not just to add more customers, but to grow significantly within its existing customer base.
The stock's valuation is steep, no question. However, given the breadth of use cases across industries for which AIP can be used, the company has the potential to become one of the largest AI companies in the world in the future.

1 Reason to Buy Solana (SOL)
Key Points Solana hasn't kept up with the rest of the crypto market. However, the lightning-fast blockchain is seeing significant growth in tokenized RWAs. 10 stocks we like better than Solana › Solana (CRYPTO: SOL) has recently disappointed investors. It's down 1% over the last year (as of July 30), which looks particularly poor considering that crypto has been in a bull market. In fact, out of the top 10 cryptocurrencies by market cap, Solana has performed the worst over the last year. But circumstances can change quickly in the crypto market, and Solana has a new use case that could help it rebound. Solana is a hotspot for tokenization This year, Solana has seen rapid growth in tokenized real-world assets (RWAs). These are crypto tokens on a blockchain that represent a physical asset or a financial instrument. For example, you can buy tokenized equities on Solana that are equivalent to stock shares. The selection of equities is a lot smaller than what you'd find in your brokerage account, at least for the time being. But you can invest in tokenized versions of dozens of companies, including Tesla, Palantir Technologies, and Nvidia. The number of RWA holders on Solana has increased by 1,281% this year to nearly 63,000. Total RWA value has increased by 176% to $479 million, and Solana could be on the cusp of greater growth in this area. BioSig Technologies recently announced it will invest as much as $1.1 billion in physical gold bullion for its treasury. It also plans to issue gold-backed crypto tokens using Solana. This could potentially triple Solana's RWA value and attract more users to its blockchain. The early stages of tokenized RWAs RWAs have just started taking off, but they have the potential to drastically increase the value locked onto blockchain ecosystems. Solana's speed and ultra-cheap transactions make it well suited for RWA applications. Despite Solana's lackluster performance over the last year, it's still an exciting cryptocurrency investment that may be poised for a big move. Should you invest $1,000 in Solana right now?

Companies taking concrete steps toward capturing revenues from carbon dioxide
A CarbiCrete curing chamber in which CO2 is permanently mineralized into concrete during the curing process is seen in this undated handout photo. THE CANADIAN PRESS/Handout — CarbiCrete (Mandatory Credit) It can be used to make fuel, fertilizer, building material and even soap, but can carbon dioxide be a money maker, too? Carbon capture has long been a focus of emissions reduction efforts in Canada. It involves collecting the climate-warming gas from industrial sites and preventing it from entering the atmosphere, most often by stowing it away permanently underground. Less common has been capturing CO2 and making it into something useful. 'Carbon utilization does not have a big history. It's relatively nascent,' said Apoorv Sinha, chief executive of Carbon Upcycling. The Calgary-based company combines industrial waste products with carbon dioxide to make a cement-like product that can be used in concrete foundations and sidewalks. 'Canada actually punches well above its weight in carbon-to-value across the building material sector, even in carbon chemicals.' Storing carbon has been the automatic go-to as industry has a wealth of experience doing it at a large scale, said David Sanguinetti, interim CEO at cleantech incubator Foresight Canada. While carbon utilization has the benefit of generating direct revenues from usable products, the economics are uncertain in a lot of cases, he said. 'It's either niche or not great right now with the current state of technology,' he said. 'If you don't have a price on carbon, then a lot of the current concepts that are out there, which are technically feasible — people have done it in the lab, they've proven it out — there isn't an economic driver to make it happen.' The Canadian Gas Association commissioned a report from Foresight Canada last year into the carbon utilization market, which concluded that storing carbon from large industrial emitters is likely to beat out using it — at least for the time being. Foresight sees southwestern Ontario being a good spot for carbon utilization to take root as there are clusters of large emitters and innovation hubs, but little in the way of infrastructure for underground storage like Alberta has. CO2 utilization falls into two categories — direct use or conversion. Direct use includes the long-standing practice of injecting the gas into mature oilfields to draw more barrels to the surface. With conversion, the chemical makeup of the gas is altered to make products like aviation fuel and fertilizer. At a smaller scale, Calgary-based CleanO2 captures the gas from building heating systems and turns it into pearl ash used in its hand soap, shampoo and other products. One of the more promising applications has been using the gas in building materials so it's trapped permanently. Last week, Carbon Upcycling held a groundbreaking ceremony at the Ash Grove cement plant in Mississauga, Ont., where work on a commercial demonstration project is underway. Production is to begin next spring. CarbiCrete, based in Montreal, has developed technology for greener precast masonry and hardscapes — think concrete blocks, retaining walls and paving stones that can be sent to a construction site, not the ready-mix stuff churning in a truck's drum. Concrete is traditionally made up of cement, aggregate like rocks or gravel, and water. 'It's the most abundant manmade substance on the planet,' said Yuri Mytko, CarbiCrete's chief marketing officer. 'But cement has traditionally been the key ingredient and cement is hugely problematic in that it accounts for about eight per cent of the world's greenhouse gas emissions.' CarbiCrete uses steelmaking slag instead of cement, and cures it in a chamber with CO2 instead of applying heat and steam. 'You're left with a concrete product that has the same properties as cement-based concrete, except with none of the emissions associated with it and also with carbon having been permanently mineralized and removed from the atmosphere,' said Mytko. CarbiCrete licenses its technology to concrete product makers and helps them retrofit their plants. Dave Sawyer, principal economist at the Canadian Climate Institute said utilization can work by helping companies generate credits to sell, but it's a relatively small piece of the emissions-reduction picture. Carbon capture, utilization and storage in general has been painted by business and industry as 'one big silver bullet technology,' he said, but there are other emissions-busting approaches that should be getting more attention. For example, sodium ion batteries may be just as technically feasible as carbon capture, utilization and storage — and maybe cheaper. 'But we just keep going to this big lumpy thing ... that is really cost prohibitive.' Sinha said carbon utilization gets a fraction of the support and resources of traditional storage projects, whose technology has been around for decades. 'What needs to happen is more support and a larger focus towards deploying these technologies quickly and testing them out. Because right now, just the amount of data — how to build these facilities, how to operate them — very little of it exists.' This report by The Canadian Press was first published Aug. 3, 2025.

How Should Investors View Stablecoins: As a Utility or a Speculative Asset?
Key Points Stablecoins exist to move fiat currency value onto blockchains. They shouldn't ever grow much in value. Not all of these assets are equally safe or equally easy to use. 10 stocks we like better than Tether › Cash has always been the grease of capitalism, shuffling quietly from buyer to seller so the real business can get done. In crypto, something still has to play that crucial but unglamorous role, and that something is the stablecoin. Without a trustworthy on-chain dollar to use as a medium of exchange, every trade would involve swapping in and out of volatile tokens that often experience 10% moves in a day. Yet the headlines that push stablecoins into the spotlight tend to trumpet new regulations, billion-dollar market caps, fresh exchange listings, and -- occasionally -- dramatic deviation from their intended fixed value (de-pegging) that leaves destruction in its wake. That can make them look like the next hot trade rather than the digital equivalent of the crumpled bills in a supermarket till. To decide whether they belong in your portfolio at all, it pays to separate their utilitarian purpose from their real but frequently misunderstood risks. When you hear about stablecoins, you're hearing about cash At the simplest level, a stablecoin is a crypto token designed to track the price of a target fiat currency, -- usually the U.S. dollar -- so that people can send, store, and settle value on-chain without worrying about minute-by-minute price swings. USDC (CRYPTO: USDC) is the poster child for this model, and the second largest of all stablecoins. Every token is said to be backed 1-for-1 by cash and short-term U.S. Treasury bills held by the issuer Circle, with independent attestations posted monthly. Meanwhile, Circle's own valuation ballooned to roughly $60 billion as USDC's circulating supply hit $61.3 billion in June -- though the company now has a market cap of $46.2 billion, whereas its coin's value now is about $64 billion. Tether's stablecoin, USDT (CRYPTO: USDT) -- the sector's biggest stablecoin with a market cap of $164 billion -- publishes daily snapshots that claim its reserves exceed liabilities, though critics note that the level of detail in its disclosures varies. And, in late 2024, Ripple USD (CRYPTO: RLUSD) entered the fray, pitched by Ripple Labs as an institutional investor-friendly alternative that lives on XRP 's chain but is quickly finding retail takers, too. Viewed through that lens, holding a stablecoin is less an investment than a convenience fee. You trade the rock-bottom risk of a bank deposit for the same amount of purchasing power embedded on 24/7 blockchain rails and near-instant transaction settlements. If your goal is long-term capital appreciation, then assets like other cryptocurrencies or equities or even fairly conservative bonds will almost certainly do incalculably more heavy lifting. But if you routinely move funds between exchanges, stake in yield pools, or settle invoices with global partners, the ability to snap digital dollars across chains is invaluable. These risks could turn utility into liability Stablecoins are, at this point of their maturity as an asset, riskier than holding the equivalent amount of cash. For stablecoins, stability hinges on three pressure points that every investor should keep in mind. First, there's asset issuer quality. Fully collateralized coins can break their peg if the issuer's reserves prove shakier than advertised or if they are frozen by regulators. If you're going to hold significant value in a stablecoin, read the attestation reports and audits, not the marketing copy. And check the price history for any evidence of past de-pegging. Second, there are chain and bridge risks to consider. In the same vein, there are also interoperability risks or, more colloquially, the risk that the stablecoin you own is not compatible with the blockchain that you want to do business on. As an example, a USDT stored on Ethereum is not the same asset as a USDT bridged to Solana, and moving between chains relies on third-party bridges that have been prime hacker targets, and which also tend to incur fees. Developers are racing to build native cross-chain standards, but for now, every hop between chains introduces another potential point of failure. To be clear, this issue is common to many types of cryptocurrencies, but it's important to identify it specifically in the context of stablecoins because of the (incorrect) assumptions that investors often have about them due to their interchangeability with cash. Third, not all pegs rely on holding old-fashioned cash -- much to the detriment of their holders. Algorithmic models in the past have attempted to hold parity through burn -and- mint mechanics, which reduce or add coins to the supply to maintain the $1 equilibrium point. But during times of market turmoil, rapid withdrawals can lead to oversupply and breaking the peg. Investors who mistake such structures for a boring digital dollar end up learning the hard way that complexity and leverage can masquerade as stability right up until they don't. So where does that leave the long-term investor? Treat stablecoins as working capital, not high-yield savings. It's not a bad idea to diversify across at least two issuers, and favor tokens that publish frequent, detailed reserve attestations. If you operate on multiple chains, consider maintaining the native version of a coin on each chain rather than relying on bridges. Lastly, remember that new jurisdictions, from the U.S. Congress to Hong Kong's monetary authority, are rolling out licensing regimes that may well reshuffle the leaderboard of the top or best stablecoins in short order.
