 BREAKING: Grok 4.5 goes public tomorrow, Elon Musk says
 The model runs on SpaceXAI's V9 foundation at ~1.5 trillion parameters. That is roughly 3x the size of the model powering Grok today.

Musk took to social platforms to characterize the model as “Opus-class,” drawing a direct comparison with Anthropic’s Claude by asserting that Grok 4.5 delivers “faster, more token-efficient, and lower cost” performance.
The development of Grok 4.5 utilized xAI’s cutting-edge V9 foundation architecture, boasting 1.5 trillion parameters. Musk disclosed earlier this July that the system had begun closed beta evaluation at <a href="https://coincentral.com/spacex-spcx-stock-slides-7-is-the-nasdaq-100-bump-already-priced-in/" rel="noopener noreferrer nofollow">SpaceX</a> and Tesla facilities.
Grok 4.3, the prior release, debuted in April. Musk had been signaling an enhanced version was in development since that time.

xAI merged with SpaceX in February 2026, subsequently rebranding as SpaceXAI. The Grok product family now represents a central element of SpaceX’s artificial intelligence market expansion, complementing its aerospace and satellite operations.
The Grok 4.5 debut arrives amid intensifying competition within the generative AI landscape. <a href="https://coincentral.com/openai-finally-gets-the-green-light-gpt-5-6-drops-this-thursday/" rel="noopener noreferrer nofollow">OpenAI</a>, Anthropic, and Google have each introduced progressively sophisticated models throughout the previous twelve months.
OpenAI has scheduled GPT-5.6’s public introduction for Thursday. The company postponed that launch last month following government concerns regarding potential exploitation by malicious entities.
Market observers are tracking how rapidly Grok 4.5 can capture consumer and enterprise adoption. Robust market acceptance would bolster SpaceX’s artificial intelligence revenue objectives.

Tuesday represented SpaceX stock’s debut trading session following its addition to the Nasdaq 100 index. Shares declined nearly 7% during the session, caught in a wider technology sector downturn.

Multiple Wall Street research firms launched coverage with Buy recommendations, yet this failed to provide support for the stock. Market participants maintained a cautious outlook.
SpaceX equity showed strength immediately following its initial public offering, though those early advances dissipated rapidly. As of Tuesday’s trading close, shares have declined approximately 7% from their June 12 market debut.
Wednesday’s pre-market activity showed the stock advancing 0.12%, representing a slight rebound before the Grok 4.5 availability.
SpaceX maintains a Strong Buy consensus among analysts tracked by TipRanks. The consensus price target sits at $212.08, suggesting potential upside of roughly 46% from present valuation levels.
