Rigetti, meanwhile, drifted in the opposite direction. If this were a race, one runner is sprinting while the other appears to be looking for the concession stand.</p><p>Still, neither company is close to profitability. Both stocks remain heavily shorted and prone to sharp swings. Many analysts have issued bullish ratings on Rigetti and IonQ, but I’d call that speculative in this early era. It’s just too hard to pick long-term winners in the quantum computing industry in 2026.</p><p>The technology is promising, but the commercial applications are mostly theoretical so far. Both of these stocks carry enough volatility to ruin your week and nosebleed-inducing valuations.</p><p>Pure-play quantum computing stocks may have a lot of upside, but only if you pick the right names long before they turn profitable.</p><p>Investors who want quantum exposure without the ulcer might consider tech giants such as <strong>Alphabet</strong> or <strong>IBM </strong>instead. Both are serious players in quantum research, and both have the minor advantage of actually making money.</p><h2>Should you buy stock in IonQ right now?</h2>

<p>IonQ's revenue surged from $11.4 million in Q2 2024 to $64.7 million in Q1 2026, while Rigetti's revenue declined from $3.1 million to $1.9 million during the same period. Despite IonQ's impressive growth, both companies remain unprofitable and face significant volatility. Analysts have mixed opinions on their long-term prospects, with many suggesting that investing in established tech giants like Alphabet or IBM may be a safer alternative for exposure to quantum computing.</p>
