BlackBerry shares jump 18% on strong QNX automotive software growth, leading AI stock rotation.

BlackBerry shares surged 18% following its Q4 FY2026 report, driven by 20% year-over-year growth in its QNX automotive software segment, now embedded in over 275 million vehicles. This growth positions BlackBerry as a leader in software-defined vehicles, with new design wins at BMW and Volvo. Meanwhile, Mobileye and Aurora Innovation also gained, reflecting optimism in automotive AI, while NVIDIA dipped slightly despite strong overall revenue. Investors are watching if BlackBerry can sustain gains amid a bullish outlook tempered by valuation concerns.
