Rigetti Computing (RGTI) shares plummeted 5.03% in pre-market trading on Thursday, January 23rd, as investor concerns over the company's prospects in the quantum computing space mounted following skeptical comments from CNBC's Jim Cramer.

Cramer expressed doubts about the hype surrounding quantum computing stocks like RGTI, stating, "Rigetti, RGTI, is a quantum company that was less than a dollar two months ago. They tried to gun it up, uh early morning, between four and five, they took it up higher and now they are wearing it."

The veteran investor's remarks highlight the growing concerns among analysts and investors about the viability of quantum computing technology and its potential impact on the market. Despite the optimism surrounding the field, many remain skeptical about the ability of companies like Rigetti Computing to deliver on their promises in the near future, contributing to the stock's decline.
