- Rigetti showed modest revenue growth and improved margins but faces widening operating losses despite holding more than half a billion dollars in cash.
- Investors appear to be differentiating among quantum computing stocks rather than rewarding the entire industry equally following this week's earnings reports.

Investors have been unable to make up their minds about how to treat quantum computing companies in recent quarters. The shares of many quantum firms skyrocketed in late 2025, followed by significant declines this year and overall volatility. There is still a mixture of enthusiasm surrounding breakthrough technology and market skepticism about the prospect of commercializing quantum products.
This week's earnings from quantum companies, including IonQ Inc. (NYSE: IONQ), Rigetti Computing (NASDAQ: RGTI), and D-Wave Quantum Inc. (NASDAQ: QBTS), reinforced both sides of that debate. Many pure-play quantum firms are continuing to see meaningful technological progress and even impressive growth in customer demand. However, the market's reaction suggests that differentiation is taking place, as investors are no longer rewarding each quantum company equally for wins across the industry. In the latest round of earnings, one winner appears to emerge.
IonQ Has Managed to Separate Itself From the Broader Quantum Pack
Among the three major quantum firms that reported, IonQ differentiated itself with the strongest earnings report of the week. The company beat Wall Street estimates for both top- and bottom-line performance, generating losses per share of 33 cents (significantly narrower than last year and the 56 cents predicted by analysts) while posting 287% year over year (YOY) revenue growth that was nearly $14 million above expectations.
Almost quadrupling quarterly revenue YOY meant IonQ generated more than $80 million in sales, helping fuel management's optimism that the firm can achieve full-year revenue between $280 million and $290 million. At those figures, IonQ is generating real revenue, and a path toward profitability may suddenly be emerging.
Helping to fuel this growth was IonQ's $1.8-billion SkyWater acquisition, providing the company a dedicated foundry operation that should cut costs and improve efficiency, making it easier for IonQ to hit its target of commissioning 256-qubit systems for customers in H1 2027. It will also help the firm meet growing demand; 60% of Q2 revenue came from commercial customers, an important milestone.
Still, IonQ remains driven by investments and reported negative adjusted EBITDA of $120 million, as well as significant GAAP operating expenses exceeding $417 million. The cost of doing business as a quantum computing firm remains significantly high. However, the confidence that IonQ management brought to earnings may inspire optimism among investors keen to see a leader emerge in the space.
Rigetti Is Making Progress, But at a Slower Pace
Rigetti's Q2 2026 earnings are a bit more complicated. On one hand, the firm posted a very modest revenue beat as sales climbed to $5.1 million from $1.8 million the year prior. Gross margin also improved substantially, reaching 43%, up from 31% in the prior-year quarter.
The firm is also anticipating a significant boost to revenue later in the year, as it remains on track to recognize a sale of more than $8 million in Q4 and is poised to receive a major benefit from the Department of Commerce.
Rigetti's balance sheet strength is also robust (something that was called into question for its competitor, D-Wave, after its most recent earnings report), as the firm continues to hold more than half a billion dollars in cash while carrying no debt.
However, there are also glaring concerns, which may be why RGTI shares fell in the hours following its earnings release. For one thing, its revenue remains substantially smaller than rival IonQ, and it is still heavily dependent upon a single system sale here or there to drive these figures. Perhaps more importantly, operating losses continue to widen. Operating expenses surged to $30.3 million in Q2, leading to non-GAAP net losses of about $16 million last quarter.
Rigetti faces substantial pressure, reflected in mounting expenses and losses, and has so far not been able to increase sales to meet those demands. The situation is not dire, given the company's strong cash reserves, but investors are likely looking for better progress toward commercialization.
Differentiation Becomes the Name of the Game
With other quantum firms, like Quantum Computing Inc. (NASDAQ: QUBT), reporting the week after these major players, investors may be watching for confirmation that the industry is indeed becoming more selective.
IonQ shares have soared by 19% in the last five days of trading, while QBTS stock is up 12% over the same period. This could once again be a bullish period for the quantum industry overall, but it increasingly appears that companies better able to distinguish their performance may be more heartily rewarded.
