D-Wave Quantum

Sales grew 178 percent over the past year, meaning revenue nearly tripled. That kind of jump says real businesses are now writing real checks for quantum computing instead of just running free experiments.

Heavyweights like Mastercard and Lockheed Martin are paying customers, and the customer base has kept climbing past 130. When companies that size trust the machines with actual work, it tells you the technology is past the science fair stage.

Net margins sit at 0 percent, so D-Wave still keeps nothing from every dollar it brings in. Building quantum machines is brutally expensive, and until that changes they have to keep going back to investors for more money.

This is one of the most volatile stocks out there, with a beta of 2.16, meaning it moves more than twice as hard as the market in both directions. The company's value has already slid from around 8 billion dollars to roughly 6 billion, so expect a bumpy ride.
