Quantum Computing Inc. (NASDAQ:QUBT) is one of the best “moonshot” tech stocks to buy according to short sellers. The stock’s latest publicly reported short interest stood at 32.73% of float as of April 30, 2026, according to MarketBeat.
QUBT fits the title almost too neatly: speculative quantum tech, heavy short interest, and a business still trying to prove that early commercial traction can become something larger. The company gave bulls a recent data point on May 11, when it reported first-quarter revenue of $3.7 million, up from just $39,000 in the prior-year period, though QCI said the increase was driven mainly by its February acquisition of Luminar Semiconductor. Quantum Computing also reported a net loss of $4.1 million, or $0.02 per share, compared with net income of $17.0 million a year earlier, though that prior-year result was helped by non-cash derivative gains.

The short-seller case is still obvious. QUBT remains an early-stage photonics and quantum optics company operating in a field where commercial timelines are uncertain, revenue is still small, and investor enthusiasm can run ahead of real adoption. That is exactly why it works as a moonshot stock, but not as a quiet compounder. The bull case is that its photonic chips, quantum machines, and foundry services become more relevant as customers test quantum and optimization workloads. The bear case is that the technology takes longer to scale than the stock market’s patience allows.
Quantum Computing Inc. (NASDAQ:QUBT) develops integrated photonics, quantum optics, quantum machines, reservoir computing systems, and related hardware and software for optimization, sensing, imaging, cybersecurity, and other advanced computing applications.
