Shares of Rocket Lab (RKLB) fell 11.9% on June 2, 2026, following a Blue Origin rocket explosion that intensified concerns about satellite deployment delays and sector-wide risks.

The previous significant move occurred on May 23, 2026, when shares gained 7% on progress toward a U.S.-Iran peace agreement.
