SpaceXAI's Grok 4.5 Launch Lifts SPCX to $150 in AI Race

SpaceXAI shares rose 1.15% to $150 on July 9 after the release of Grok 4.5, the first model built jointly with Cursor, narrowing the gap with Anthropic, OpenAI and Google. The launch caps a rapid July progression that began with the July 1 debut of a no-code voice agent builder, followed by the July 6 rebrand from xAI and plans for a joint model rollout. Key milestones include SpaceX’s $75 billion June IPO, the $60 billion Anysphere acquisition, Nasdaq-100 inclusion, and $12.7 billion in 2025 AI capex, positioning AI as a third growth engine alongside Starlink and launches.
