Short Sellers Target Quantum Stocks as QUBT Short Interest Tops 26%

6 articles · Updated · Bankless Times · May 22

QUBT short interest has climbed above 26%, with IonQ at 22.43%, Rigetti at 15% and D-Wave at 14.25%, signaling rising bets against the sector’s rally.
Valuation concerns are driving that skepticism: IonQ is worth more than $23 billion on expected 2026 revenue of $268 million, while Rigetti’s $8.6 billion valuation compares with just $23 million in expected 2026 sales.
Rigetti trades at a forward price-to-sales ratio of 309, far above Nvidia’s roughly 12, underscoring investor worries that quantum shares have outrun fundamentals.
The bearish positioning comes even as the Trump administration unveiled $2 billion for quantum-related investments and Nvidia expanded backing for startups, helping push the group’s combined value above $40 billion.
Commercial adoption remains the key constraint, with practical quantum uses still largely experimental and some estimates suggesting scalable breakthroughs are decades away.
