Quick Read

  • SPY gained 2% on the day, with a falling VIX lifting speculative, high-beta names across the tape.

  • IonQ leads its peers with $64.67M in Q1 revenue and raised FY2026 guidance to a range of $260M to $270M, yet trades at a steep 115x price-to-sales ratio.

Rigetti Computing (NASDAQ:RGTI) stock is up 9% to around $22.92, and IonQ (NYSE:IONQ) stock has gained 6% to around $61.51. The four names are once again trading in lockstep as a thematic basket.

There's no identified company-specific catalyst behind the move in QUBT, QBTS, RGTI, or IONQ stock. The likely backdrop is a broad risk-on tone following the U.S.-Iran peace agreement announced Sunday, with a formal signing referenced for June 19, which has lifted speculative, high-beta names across the tape.

Risk-On Tape, Not a Quantum-Specific Story

The CBOE Volatility Index (VIX) dropped Monday morning to 16.24, well below the recent intraday peak of 22.22 on June 10 and far off the March 27 high of 31.05. That volatility contraction has been supportive for the most speculative corners of the market, and quantum-computing names like IonQ and Rigetti sit squarely in that bucket.

The S&P 500 tracking SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is up 1.67% in Monday's session, providing a benign macro tape. Against that backdrop, the quantum basket including QUBT and QBTS stock is outperforming on relative beta rather than any fresh sector news.

Speculative Names Snapping Back

Quantum Computing Inc. has been the laggard of the group, with QUBT stock down 34% over the past year. The company posted Q1 2026 revenue of $3.69 million, lifted by its February Luminar Semiconductor and NuCrypt acquisitions, with about $1.4 billion in total cash and investments on the balance sheet.

In contrast, D-Wave Quantum stock is up 72% over the past 12 months. The company reported Q1 2026 bookings of $33.4 million, ended the quarter with $588.4 million in cash, and held an Investor Day at the NYSE on June 1 highlighting a gate-model roadmap targeting 100 logical qubits by 2032.
