Is it hype or a $100 billion opportunity?

The total addressable market for quantum computing and IonQ could reach $100 billion in the next decade. There's still plenty of risk in quantum computing. Across the quantum computing industry, there's a lot left to prove. Commercial viability is still in its early stages, and it may fall short of the hype.

Quantum computing is also a capital-intensive endeavor. IonQ reported research and development costs of $62.9 million in its latest quarter, along with total operating costs exceeding $208 million. This is compared to just $39.8 million in revenue.

Is IonQ stock a buy?

IonQ stock is expensive right now. The stock has increased by over 63% in the past 12 months. Its price-to-sales ratio is 153 as of Jan. 9. The company's market capitalization is a whopping $17.5 billion. Is it justified? If quantum computing and IonQ's ability to achieve 99.99% fidelity keep it head and shoulders above competitors, then the stock's price is well worth the future revenue IonQ could produce.
