The 2 Best Quantum Computing Stocks to Buy in March
The Motley Fool·2026-03-01 20:05

Core Viewpoint - Quantum computing stocks are experiencing significant declines, with IonQ down 34%, Rigetti Computing down 32%, and D-Wave Quantum also facing similar challenges. Despite the drop, these stocks are not considered bargains, and there are better investment options in the quantum computing space [1]. Valuation Concerns - Valuations in the quantum computing sector remain unrealistic, with IonQ trading at 99 times sales, D-Wave at 217 times sales, and Rigetti at approximately 600 times sales. The revenue supporting these multiples is minimal, with D-Wave generating $3.7 million and IonQ about $40 million in their most recent quarters. These companies are increasing their cash burn rates instead of reducing losses as they scale [4]. Growth Potential and Timeline Issues - Investment in these companies hinges on their potential for future revenue growth, but there is excessive growth already priced into their stock values. The timeline for significant returns from quantum technology is uncertain, with no clear indication of when or if it will materialize [5]. Commercialization Timeline - A recent MIT report indicates that large-scale commercial applications of quantum computing are likely many years away. Morningstar's analysis suggests early commercialization could be 5 to 10 years off, while general-use quantum computing may take up to 20 years to develop, raising concerns about funding operating losses during this period [6]. Alternative Investment Strategies - Alphabet (GOOG) is highlighted as having a leading quantum research program, with significant resources to support ongoing quantum R&D. The company has achieved a major breakthrough with its Willow chip and continues to grow its core business, including a 17% increase in Google Search revenue and a 48% surge in Google Cloud revenue [7][9]. - International Business Machines (IBM) also possesses a strong quantum program, supported by a substantial R&D budget. IBM generated $67.5 billion in revenue last year, including a decade-high $14.7 billion in free cash flow, making it a viable option for quantum exposure without the risks associated with pure-play companies [10][12].
