Top Quantum Computing Shares Endorsed by Wall Street as Top Performers Today
In the rapidly evolving world of quantum computing, three companies have captured the attention of Wall Street analysts: Sealsq Corp (LAES), Arqit Quantum (ARQQ), and Quantum Computing Inc. (QUBT/QMCO). Despite their early-stage financials and premium valuations, these companies are seen as trailblazers in their respective fields, offering significant upside growth due to their leading technologies.
Sealsq Corp (LAES)
Despite a staggering 380% rise in its share price over the past 12 months, Wall Street analysts predict that Sealsq's stock can rise further. The single analyst covered by LSEG has set a 12-month price target nearly 79% above the current share price. Sealsq, based in Geneva, Switzerland, specializes in quantum-resistant chips for defense, finance, industrial applications, and IoT devices, as well as post-quantum root-of-trust and PKI services for digital signatures, email security, and secure communications. However, the company is still operating at a loss and only projects $16-$20 million in revenue for 2025, making it a risky play with much of its growth already priced in [1][2][4].
Arqit Quantum (ARQQ)
Arqit Quantum shares a similar profile to Sealsq, including a recent surge of over 320% in share price. The lone covering analyst sees about 35% upside, driven by Arqit's quantum-safe networking products like the SKA-Platform and NetworkSecure. The company also struggles with minimal revenue ($67,000 in H1 2025) and substantial losses, resulting in a premium market cap near $518 million. It remains a high-risk, high-reward investment [1][2].
Quantum Computing Inc. (QUBT, also noted as QMCO)
Quantum Computing Inc., a company with a current market cap of around $2.6 billion, is recognized as a bona fide quantum computer developer. It markets the "world’s most powerful quantum analog machine" (QCi DIRAC-3). While less speculative than Sealsq and Arqit, its fundamentals and detailed analyst outlook are less documented, indicating moderate bullish sentiment but with typical early-stage tech risks [2][3].
In summary, Wall Street analysts are bullish on these three stocks, envisioning significant upside growth due to their leading technologies in quantum computing and security. However, all exhibit substantial financial risk as none are currently profitable, and their valuations already reflect aggressive growth expectations. Investors should weigh potential high returns against significant volatility and uncertain near-term revenue growth [1][2][4].

Investors may find opportunities in the quantum computing sector with companies like Sealsq Corp (LAES), Arqit Quantum (ARQQ), and Quantum Computing Inc. (QUBT/QMCO), as their leading technologies pose significant upside growth potential. However, it is essential to note that these companies are still early-stage investments, with money tied up in technology rather than guaranteed returns, due to their current financial struggles and premium valuations.
