Quantum Computing Inc: Stock price soars on earnings beat in volatile year for quantum stocks

As of this writing, shares in Quantum Computing Inc. (Nasdaq: QUBT) are spiking in premarket trading, with the stock price up over 15%. That’s a relatively large swing, even for a quantum computing firm, where stocks have been especially volatile this year. Here’s what to know:

Why is QUBT rising today?

While quantum computing stocks have been volatile this year due in part to the speculative nature of the space, the main reason for Quantum Computing’s share price surge this morning seems more to do with the company’s finances than just standard run-of-the-mill quantum speculation.

On Friday, Quantum Computing Inc. released its third-quarter 2025 financials—and the company announced an unexpected earnings and revenue beat.

As noted by Investor’s Business Daily, Quantum Computing reported earnings per share of 1 cent. Investors had been expecting the company to post a 6-cent-per-share loss.

The company also reported revenue for the quarter of $384,000. Analysts had been expecting revenue of just $100,000.

In a press release announcing its revenue beat, Quantum Computing said that the revenue increase “is primarily due to increases in the number of, size of and level of effort performed on research and development services and custom hardware contracts.”

Stock’s reaction underscores quantum computing volatility

A quarterly revenue of just $384,000 might not excite investors in many other companies, but the revenue jump at Quantum Computing Inc. seems to have sparked a rally.

A little good news sent QUBT shares surging 15% this morning in premarket—good for QUBT shareholders. Yet those same moves also highlight the volatility of QUBT shares—and quantum computing stocks in general.

While QUBT is getting a boost today, as of Friday’s close, the stock’s price was down nearly 36% year to date.

And yet, that included a nearly 19% gain over the last six months and also a nearly 51% drop over the past month.

Those highs and lows underscore quantum computing’s volatility as Wall Street digests day-to-day news about the industry and navigates varying opinions on whether the technology will usher in the computing revolution that many exerts believe it will.

But today, at least in premarket, it seems like QUBT is experiencing what most investors would consider “good” volatility, with its 15% gains. But where the stock goes from here is anyone’s guess.

Over the last year, the stock has risen more than 140%.
