IonQ Shares Jump Nearly 11% Monday as Quantum Computing Stocks Extend Volatile Summer Rally Ahead of Earnings

IonQ shares jumped nearly 11% on Monday morning as investors positioned ahead of the company’s second-quarter earnings report next week, extending a choppy summer for quantum computing stocks. At 10:16 a.m. Eastern, the stock traded at $36.42, up $3.58 (10.90%), following sector momentum that lifted peers including Rigetti Computing and Infleqtion. The article links the broader volatility to how these companies’ valuations depend more on long-term potential than current profitability. IonQ has posted rapid revenue growth but remains unprofitable, reporting $64.7 million in Q1 revenue—up 755% year over year—while raising full-year guidance to $260 million to $270 million.
