Page 1 of 11

In this article, we will discuss the 11 Best Quantum Computing Stocks to Invest In Right Now.

According to McKinsey, when it comes to quantum technology (QT), the investment continues to surge and breakthroughs continue to multiply. The 3 core pillars of QT, i.e., quantum computing, quantum communication, and quantum sensing, can together garner up to $97 billion in revenue worldwide by 2035. McKinsey is seeing a transition from development to deployment.

Key Trends Impacting the Industry

While the QT start-up ecosystem remains a fertile ground for breakthroughs, McKinsey highlighted that well-established tech giants fueled the bulk of change in 2024. Some of the advancements from renowned companies consist of suppression of error rates relative to the number of qubits, development of multiple high-fidelity qubits, and significant reductions in the cost of quantum error correction.

McKinsey also opines that the total quantum communication market size was pegged at $1.2 billion in 2024, which is expected to reach $10.5 billion – $14.9 billion by 2035. Its research demonstrates that governments are presently the largest purchasers of quantum communication technologies, at ~57% of all purchases in 2024, while the private sector continues to increasingly adopt the technology.

By 2035, McKinsey believes that the telecommunications sector is anticipated to account for 16% – 26% of the overall spending on quantum communication products.

Amidst such favourable trends, let us now have a look at the 11 Best Quantum Computing Stocks to Invest In Right Now.

The $250 Trillion AI Hype is Real. A few years from now, you’ll probably wish you’d bought this stock.

When Jeff Bezos said that one breakthrough technology would shape Amazon’s destiny, even Wall Street’s biggest analysts were caught off guard.

Fast forward a year and Amazon’s new CEO Andy Jassy described generative AI as a “once-in-a-lifetime” technology that is already being used across Amazon to reinvent customer experiences.

At the 8th Future Investment Initiative conference, Elon Musk predicted that by 2040 there would be at least 10 billion humanoid robots, with each priced between $20,000 and $25,000.

Do the math. According to Musk, this technology could be worth $250 trillion by 2040.

Put another way, that’s roughly equal to:

  • 175 Teslas
  • 107 Amazons
  • 140 Metas
  • 84 Googles
  • 65 Microsofts
  • And 55 Nvidias

And here’s the wild part — this $250 trillion wave isn’t tied to one company, but to an entire ecosystem of AI innovators set to reshape the global economy.

It’s a leap so massive, it could reshape how businesses, governments, and consumers operate worldwide.

Even if that $250 trillion figure sounds ambitious, major firms like PwC and McKinsey still see AI unlocking multi-trillion-dollar potential.

How could anything be worth that much?

The answer lies in a breakthrough so powerful it’s redefining how humanity works, learns, and creates.

And this breakthrough has already set off a frenzy among hedge funds and Wall Street’s top investors.

What most investors don’t realize is that one under-owned company holds the key to this $250 trillion revolution.

In fact, Verge argues this company’s supercheap AI technology should concern rivals.

Before I reveal the details, let’s talk about how some of the richest people on the planet are positioning themselves.

  • Bill Gates sees artificial intelligence as the “biggest technological advance in my lifetime,” more transformative than the internet or personal computer, capable of improving healthcare, education, and addressing climate change.
  • Larry Ellison — through Oracle, is spending billions on Nvidia chips and partnering with Cohere to embed generative AI across Oracle’s cloud and apps.
  • Warren Buffett — not known for tech hype — says this breakthrough could have a ‘hugely beneficial social impact.

When billionaires from Silicon Valley to Wall Street line up behind the same idea — you know it’s worth paying attention to.

Even as we admire what Tesla, Nvidia, Alphabet, and Microsoft have built, we believe an even greater opportunity lies elsewhere…

But the real story isn’t Nvidia — it’s a much smaller company quietly improving the critical technology that makes this entire revolution possible.

And judging by what I’m hearing from both Silicon Valley insiders and Wall Street veterans…
