Shares of Rigetti Computing (NASDAQ:RGTI), Quantum Computing Inc. (NASDAQ:QUBT), D-Wave Quantum (NYSE:QBTS), and IonQ (NYSE:IONQ | IONQ Price Prediction) are extending Thursday’s sector rebound into a second straight session. In morning trading, RGTI shares are up 17%, QUBT shares are up 14%, QBTS shares are climbing 13%, and IONQ shares are rising 8%.
It’s no longer a one-day bounce. RGTI, QBTS, QUBT, and IONQ shares are now mid-way through a two-day rally with serious cumulative magnitude across the basket, extending well beyond Thursday’s single-session bounce.
24/7 Wall St. flagged Thursday’s sharp rebound across RGTI, QBTS, QUBT, and IONQ. Today’s session is stacking right on top of yesterday’s gains, and the leadership pattern inside the group is repeating almost line for line.
Day Two Stacks on Day One
RGTI shares are up 17% today, on top of Thursday’s 19% jump. Rigetti stock trades near $26, against a $22.04 prior close.
QBTS shares are up 13% today, on top of Thursday’s 19% move. D-Wave Quantum stock’s one-month gain now sits at 33%.
QUBT shares are up 14% today after rising 13% on Thursday. Quantum Computing Inc. stock has now logged a one-month gain of 27%.
IONQ shares are up 8% today, after climbing 7% on Thursday. IonQ stock remains the day’s laggard, even though its one-month gain of 31% is undeniably impressive.
Same Dispersion Pattern Repeats
The ranking within the group from Thursday is repeating today almost exactly. RGTI and QBTS, the two most beaten-down names heading into the week, are leading again on Day 2.
QUBT continues to sit in the middle of the pack. IONQ, a strong one-month and year-to-date (YTD) performer, is again bouncing the least, consistent with the classic deepest-pullback-bounces-hardest pattern playing out across two consecutive sessions.
The four companies pursue meaningfully different quantum approaches. Rigetti runs superconducting qubits, D-Wave Quantum sells annealing systems, IonQ uses trapped ions, and Quantum Computing Inc. is built around photonic technology. The basket trade tends to flatten those distinctions on momentum days.
Bull Case Versus Bear Case
The bull case rests on AI-quantum convergence narratives, growing government and defense interest, and broader speculative-name rotation. IonQ’s Q1 2026 revenue of $64.67M (up 755% year over year) and raised FY2026 guidance of $260M to $270M give the group leader real fundamental thrust, while D-Wave Quantum’s Q1 bookings of $33.4M point to commercial pull.
The bear case is straightforward. These are pre-revenue or barely-revenue companies trading mostly on sentiment, two-day vertical moves in speculative names often attract profit-takers, and competition from larger incumbents like IBM and Quantinuum continues to loom over the pure-plays.
What to Watch
Investors will watch for whether Monday brings a third consecutive up-day for the quantum basket, or whether the typical pattern of a Friday rip cooling by the next session asserts itself. D-Wave Quantum’s first-ever Investor Day, scheduled for June 1 at the NYSE, is the next dated catalyst on the calendar.
Beyond that, broader sentiment toward speculative AI-adjacent themes and any individual technical milestones could move the group. RGTI, QBTS, QUBT, and IONQ trade together, but each name has its own roadmap and its own balance sheet.
For investors in RGTI, QBTS, QUBT, and IONQ, the honest framework matters more than the headline. A two-day vertical move is real, yet pre-revenue companies trading on sentiment can reverse course just as quickly as they rallied, and prudent position sizing is the takeaway here.
