Quantum computing stocks have plummeted in November, erasing gains from a previous rally in October. Companies such as Rigetti Computing, D-Wave Quantum, and Quantum Computing have seen their shares fall by over 53% in the past month. This downturn has sparked comparisons to the dot-com bubble, with Perplexity Finance highlighting concerns over unrealistic valuations and long-term profitability challenges. Despite the current market correction, Bank of America maintains a positive outlook on the future of quantum computing. The bank projects that the quantum computing market could grow to $4 billion by 2030, underscoring its potential for long-term growth despite short-term volatility.
