Quantum computing stocks have been dropping lately after massive runs in 2024 and 2025, but Wall Street still sees a lot of upside for a few specific names. Rigetti Computing (RGTI) is down about 32% this year. They are expected to release a 108-qubit system at the end of Q1. Mizuho just reiterated a buy rating with a $43 price target, implying 162% upside from here. It is definitely a speculative play right now since they generate very little revenue and have hundreds of millions in losses. IonQ (IONQ) is down 28% this year. They recently hit a world record for error rate and are planning to demonstrate a 256-qubit system this year. Rosenblatt maintained a buy rating and a $100 price target, which implies 197% upside. IONQ is further along financially with $130 million in revenue for 2025 and $2.4 billion in cash, though they are still taking significant losses. Both are basically pure bets on whether quantum technology can actually be commercialized at scale.
