QBTS -9.12% — Breaking
By SNF Research · Independent market intelligence from Sunday Night Futures LLC
QBTS drops 9% after hours, leading quantum sector lower.
QBTS hit $19.405 in after-hours trade, down from $21.39 at the close. Sector peer IONQ is also off, sliding to $39.72 (-1%), confirming broad quantum weakness rather than single-stock noise. MSFT's 2.25% gain signals the broader tech tape isn't driving the selling.
Watch: $19.00 as the next clean support — a break opens a run toward $17.50. If IONQ cracks $39.00 overnight, quantum names face compounding pressure into Friday's open.
