Quantum Computing Inc. (NASDAQ: QUBT) ignited Wall Street buzz on Wednesday, with shares vaulting more than 25% during the session as the once-niche quantum tech space finds itself at the center of a fresh investment boom.
Trading volume surged past 128 million shares by mid-afternoon—over 30 times its daily average—as QUBT stock reached an intraday high of $20.90 before cooling slightly to trade around $19.07 at the time of writing.
The rally appears fueled by a perfect storm: improved financials, a promising pipeline of photonic breakthroughs, and a timely tailwind from none other than Nvidia CEO Jensen Huang.

During his keynote at the GTC Paris conference, Huang declared that quantum computing is “no longer decades away,” positioning it instead at a “commercial tipping point.”
That statement alone injected momentum into the entire sector, lifting stocks from household names like IonQ and Rigetti to smaller players like QUBT, which now finds itself in an unfamiliar spotlight.
“Quantum computing is entering the era of usefulness,” Huang said. “Applications once theoretical are becoming tangible.” Those few words were enough to send investors scrambling for exposure to the next frontier in computing.
A Comeback Story in the Making?
Until recently, QUBT had languished in speculative obscurity, struggling to gain traction amid fierce competition and skepticism around commercialization timelines. But 2025 has rewritten the narrative.
The company surprised analysts by turning a profit in Q1, reporting EPS of $0.11—compared to a loss of $0.08 in the prior year. That was followed by news that QUBT would be added to the Russell 2000 and Russell 3000 indexes later this month.
The company also opened a dedicated photonic chip facility in Arizona and inked a strategic collaboration with materials science firm Sanders TDI, signaling real strides in R&D and commercialization.
“Quantum Computing Inc. is not just riding the wave—it’s building surfboards,” said Andre Santos, a tech sector analyst at Elevation Capital. “This isn’t meme-stock speculation. They’ve put meaningful milestones on the board.”
Speculation or the Start of a Quantum Shift?
Despite today’s euphoria, skeptics remain. QUBT is still trading roughly 70% below its all-time high, and insider selling in May raised eyebrows.
Financial metrics like a negative net margin in the double digits cast a long shadow over short-term optimism. GuruFocus currently pegs the stock’s fair value closer to $1.50—less than a tenth of its current price.
But in a market hungry for transformational stories, quantum computing offers exactly that.
“This is the AI moment all over again—but for physics,” said Maria Chen, lead strategist at Quantum Horizons ETF.
“Quantum will not replace classical computing, but it will augment it in powerful, niche ways. The market is pricing in that promise, not present performance.”
What Comes Next?
Whether QUBT can sustain its rally will depend on how well it executes over the next few quarters.
Institutional buying interest is rising, and Ascendiant Capital recently upgraded the stock to “Buy,” lifting its price target from $14 to $22. Still, QUBT will need more than momentum to justify its current valuation.
For now, it’s clear that quantum computing has captured investors’ imaginations again—and QUBT has emerged, for the moment, as one of the market’s boldest bets.
