Prediction This Quantum Computing Stock Will Be Worth More Than

Written by Will Healy for The Motley Fool-> IBM built its first quantum computer in 2019. Unlike most of its quantum peers, IBM earns a profit. Its start-up competitors trade at nosebleed valuations. Quantum computing stocks benefited from enormous success in 2025. Over the last year, start-up companies in this industry, like Rigetti Computing and D-Wave Quantum, rose more than 600%.

Pure-play quantum computing stocks got Wall Street's attention in 2025 as JPMorgan, Jefferies, Evercore ISI, Cantor Fitzgerald and Mizuho Securities initiated coverage on some companies while Barclays and Bank of America published in-depth reports... Heading into 2026, IonQ (IONQ) and D-Wave Quantum (QBTS) hold the most buy ratings along with the highest price targets on average… 9:00 AM ET The stock market fell to end a solid 2025.

Quantum computing stocks are gaining attention as the technology promises to revolutionize industries with its unprecedented computational power. Smaller, "pure-play" quantum computing stocks are considered more speculative, as the technology is still in its early stages and widespread commercial applications are yet to be realized, but a number of larger and more... Investors interested in quantum computing stocks should be prepared for volatility and long-term investment horizons.

Honeywell stock is down 8% in 2025 and remains an attractive investment, given its majority stake in Quantinuum, a quantum computing company. D-Wave stock soared Monday after management announced plans of participating in the CES 2026. Jefferies sees QBTS shares hitting $45 in the coming year. IonQ grabbed headlines on a Trump investment prediction, yet the stock’s fate still hinges on execution, not speculation. IonQ’s stock has suffered a sharp decline amid a quantum computing sector cooldown despite analysts’ continued optimism for significant long-term growth potential. Google parent Alphabet is already nearly worth more than Berkshire, Palantir, and Tesla combined.

If a few key assumptions hold up, the stock should be larger than these three companies within the near future. Quantum computing probably won't be Alphabet's biggest growth driver, though. What do Berkshire Hathaway (NYSE: BRK.A) (NYSE: BRK.B), Palantir Technologies (NASDAQ: PLTR), and Tesla (NASDAQ: TSLA) have in common? Not much. However, they're all large-cap companies that have achieved significant success in recent years. There's one common denominator we can definitely cross of the list: None of these three companies has quantum computing developments underway.

But another tech giant does. And I predict it will be worth more than Berkshire, Palantir, and Tesla combined by 2030. Quantum computing exploded onto the investment scene in late 2024, igniting a frenzy that propelled pure-play stocks to astronomical heights. Rigetti Computing (RGTI) emerged as one of the biggest beneficiaries, with shares rocketing over 800% in a single month amid breakthrough announcements and surging optimism. Over the past three years, RGTI has delivered staggering gains of more than 3,200%, and at its peak, the stock was up over 8,200% from historic lows. Early investors have undeniably struck a rich motherlode, turning modest bets into life-changing wealth.

Yet for those new to the quantum sector, the ride has been brutal. On Friday, RGTI tumbled almost 9% to close 61% below its October high of $58, erasing much of the year's explosive gains. This pullback mirrors broader pain across quantum stocks like IonQ (IONQ) and D-Wave (QBTS), which have also plunged sharply after similar booms and busts. With the entire sector reeling, investors need to ask: Is the hype surrounding quantum computing finally over – and is RGTI still a buy? Quantum computing harnesses principles of quantum mechanics, using qubits that can exist in multiple states simultaneously (superposition) and become entangled. Unlike classical bits limited to 0 or 1, this enables quantum systems to explore vast solutions exponentially faster for certain problems.

The potential is transformative: faster drug discovery by simulating molecules, optimized financial models, unbreakable encryption breakthroughs, and efficient logistics routing. Quantum could reshape industries from pharmaceuticals to materials science, unlocking solutions classical computers can't touch in reasonable time.
