5 Quantum Computing Stocks Investors Should Be Watching in 2027
For many years, quantum computing was little more than a weird, niche lab project that investors read about, but that relatively few bought into. 2026 changed that. A wave of companies went public through mergers and listings, and names most people ignored a year ago now carry market values in the billions. Some of them build actual quantum computers. Others make the lasers, chips, and security tools that those machines need. Here are five I think deserve a spot on your quantum computing stock list heading into 2027, with what each company is doing and where the trouble spots are. Image source: Getty Images. 1. Quantum Computing Quantum Computing Inc. (QUBT +0.58%) started as a small software operation, but it's a much different business now. Through a series of acquisitions, including Luminar Semiconductor, it runs its own chip manufacturing and offers foundry services for thin-film lithium niobate chips. Those chips transmit data via pulses of light rather than electricity, which increases signal speed and generates less heat. As of its last quarterly report, the company had about $1.3 billion in cash and investments on its books, which gives it some room to keep buying. The concern for investors is that most of its growth has come from those acquisitions. First-quarter revenue jumped from $39,000 to $3.7 million, a rise the company tied to its purchase of Luminar Semiconductor, and it has spent about $180 million in cash on acquisitions so far this year. The question is how well all of these acquired businesses will fit together and whether customers will pay for the result.
