Nvidia Ising Buzz Lifts NVDA to $215.16 as Quantum Ecosystem Rally Persists

Nvidia shares hit $215.16 (+1.73%) on May 9, pushing market cap above $5.1 trillion amid sustained excitement over the Ising launch. Unveiled May 2, Ising delivers open-source AI models for quantum error-correction decoding—2.5x faster and 3x more accurate—mirroring Nvidia's CUDA strategy and targeting a $11B-$100B market. Initial reaction muted with NVDA at $198.61 (-0.48%) on May 3, but quantum peers surged May 4 (IonQ +21%, Rigetti +13.3%, D-Wave +22.6%), signaling ecosystem adoption and Nvidia's infrastructure role.
