Shares of D-Wave Quantum Inc. (QBTS) are having a very good Wednesday, charging higher by more than 15%. But this isn't just a D-Wave story—it's a quantum computing party, and the invitation came from an unlikely host: the GPU giant NVIDIA Corp. (NVDA).
The catalyst? On Tuesday, Nvidia launched something called Ising, which it bills as the world's first open-source quantum AI model family. Think of it less as a product and more as a toolkit. These new models are designed to tackle one of the gnarly, behind-the-scenes problems in quantum computing: calibrating the processors. It's the kind of tedious engineering work that's essential but not glamorous, and Nvidia says its AI can do it up to 2.5 times faster than old-school methods.
"AI is essential to making quantum computing practical," stated Nvidia CEO Jensen Huang. He framed Ising as allowing AI to become the "operating system of quantum machines." That's a pretty big vision—turning AI from an application *on* a computer into the fundamental layer that makes a new type of computer work. It's the kind of announcement that makes investors sit up and remember that the quantum computing market is projected to be worth over $11 billion by 2030.
And remember they did. The news sparked a sector-wide rally. It wasn't just D-Wave moving; peers like IonQ (IONQ) and Rigetti Computing (RGTI) also posted double-digit gains. QBTS rose over 15.84% during Tuesday's session and kept climbing in Wednesday's premarket. When a titan like Nvidia leans into your niche, it tends to validate the entire field and send money looking for pure-play opportunities.
Adding some fuel to the fire is the short interest dynamic. Recent data shows short interest in QBTS increased from 54.36 million to 58.77 million shares. That represents 16.41% of the company's public float. Based on average daily volume, it would take short sellers about 2.78 days to cover all their positions. When a heavily shorted stock gets good news, the resulting rally can force those shorts to buy back shares to limit losses, creating a feedback loop that pushes prices even higher—a classic short squeeze scenario.
There's also a fascinating competitive subplot here. D-Wave's own CEO, Alan Baratz, recently turned up the heat on Nvidia. "If I was Nvidia, I'd be shaking in my boots," Baratz told Yahoo Finance. His argument is straightforward: quantum computing will eventually challenge GPU dominance in AI. "We're not waiting for the future—we're building it," he added. So, while Nvidia is providing tools that could help quantum companies like D-Wave, D-Wave's CEO is openly framing his technology as the eventual disruptor to Nvidia's core business. It's a reminder that in tech, today's collaborator can be tomorrow's competitor.
As of Wednesday's premarket trading, the momentum was holding. D-Wave Quantum shares were up 10.67% at $18.78, according to market data. The story here is part technical breakthrough from Nvidia, part sector-wide re-rating, and part a squeeze on skeptics—all wrapped up in the long-term promise that quantum computing might finally be moving from the lab toward something practical.
