- The billionaire CEO positioned the AI model as “Opus-class,” asserting it delivers superior speed, enhanced token efficiency, and reduced operational costs compared to Anthropic’s Claude offering
- The advanced Grok 4.5 leverages xAI’s cutting-edge V9 foundation architecture featuring 1.5 trillion parameters
- In its inaugural trading day as a Nasdaq 100 constituent, SpaceX shares tumbled approximately 7%, though modest gains appeared in Wednesday’s pre-market activity

On Tuesday night, Elon Musk revealed that the public rollout of Grok 4.5 is scheduled for Wednesday, July 9. This marks the newest iteration of the signature artificial intelligence platform from SpaceXAI, the division previously operating under the xAI brand.
Taking to social media platforms, Musk characterized the advanced model as “Opus-class” technology. In a direct competitive jab, he positioned Grok 4.5 against Anthropic’s Claude system, asserting his model delivers “faster performance, superior token efficiency, and reduced operating expenses.”
The development of Grok 4.5 was executed using xAI’s groundbreaking V9 foundational architecture, a massive neural network containing 1.5 trillion parameters. Earlier this month, Musk disclosed that the system had progressed to private beta evaluation phases at both SpaceX and Tesla facilities.
The company rolled out Grok 4.3, the preceding version, back in April. Following that launch, Musk consistently hinted at forthcoming enhancements.
AI Strategy Takes Center Stage at SpaceX
xAI merged with SpaceX during February 2026 and underwent rebranding as SpaceXAI. The Grok series of AI models now represents a strategic pillar in SpaceX’s diversification strategy, complementing its established aerospace and satellite communications operations.
The introduction of Grok 4.5 arrives amid escalating rivalry within the generative artificial intelligence sector. OpenAI, Anthropic, and Google have each unveiled progressively more sophisticated language models throughout the previous twelve months.
OpenAI has scheduled the public debut of GPT-5.6 for Thursday. The company pushed back that launch date last month following government officials’ concerns regarding potential exploitation of the system’s capabilities by malicious entities.
Market analysts will closely monitor adoption rates among both individual users and enterprise clients for Grok 4.5. Robust market acceptance would validate SpaceX’s strategic pivot toward AI-generated revenue streams.
Share Price Volatility for SPCX
Tuesday represented SpaceX’s maiden trading session following its inclusion in the Nasdaq 100 index. Shares declined nearly 7% throughout the session, caught in a wider technology sector downturn.

Multiple prominent Wall Street research firms unveiled coverage with Buy recommendations, yet these endorsements failed to provide upward momentum. Market participants maintained a wait-and-see approach.
Following an encouraging post-IPO performance, SpaceX equity has surrendered initial gains rapidly. Based on Tuesday’s closing price, shares have retreated approximately 7% from the June 12 initial public offering.
During Wednesday’s pre-market session, the stock registered a modest 0.12% advance, suggesting tentative optimism ahead of the Grok 4.5 availability.
Analyst consensus on TipRanks currently assigns SpaceX a Strong Buy rating. The mean price objective sits at $212.08, representing potential appreciation of roughly 46% above present trading levels.
