Quantum Computing Stocks Rebound in May as IonQ’s $470 Million Backlog Sets Pace

6 articles · Updated · heygotrade.com · Jun 1

May trading revived the quantum sector after an early-2026 slump, with 20%+ single-day jumps common and standout sessions including Rigetti up 24% and D-Wave up 25%.
Stronger Q1 results drove the rebound, led by IonQ after remaining performance obligations surged 554% year over year to about $470 million, backed by a $39 million Space Development Agency contract.
IonQ also entered June with the strongest balance sheet—$3.1 billion in cash and investments despite a $271 million operating loss—while Rigetti posted a $26 million operating loss on $4.4 million in revenue.
Dilution remains the key risk for weaker names: D-Wave’s diluted share count rose to more than 367 million from about 286 million a year earlier, and Quantum Computing Inc. traded at more than 600 times sales.
The report’s June stance favors IonQ as a core add, Rigetti as a watch-with-conviction name, and D-Wave and QUBT as smaller watch-only positions because commercial payoffs are still years away.
