## Summary

SpaceX shares rose 0.2% overnight after CEO Elon Musk stated on X that the company could develop an AI model comparable to Anthropic's Claude Fable and OpenAI's GPT-6 within two to three months. Musk added that SpaceX could potentially lead the field within six months, citing the company's ability to rapidly deploy large amounts of computing power. He described the AI effort as younger than rivals' but emphasized hardware capabilities as a key advantage.

This statement follows the recent launch of Grok 4.7, which Musk positioned as a cost-effective "everyday workhorse" for agentic coding. In a previous roadmap, Musk predicted Grok 4.9 would match the class of OpenAI's Astra and Anthropic's Fable, while Grok 5 might surpass all existing models. He also noted that Grok 4.8 is a 2.5-trillion-parameter model currently undergoing initial training.

SpaceX's AI segment generated approximately $2.56 billion in revenue during the second quarter. While Musk previously promised new models trained from scratch every month for the rest of 2026, the actual release cadence for Grok 4.5, 4.6, and 4.7 has not met that specific monthly promise, though releases have continued.

## Key points

- Musk claims SpaceX can match Anthropic’s Fable and OpenAI’s GPT-6 within two to three months.
- SpaceX AI segment generated about $2.56 billion in second-quarter revenue.
- Grok 4.7 launched this week, ranking third in agentic coding behind Anthropic and OpenAI.

## Why it matters

SpaceX entering the frontier AI race with significant hardware advantages could intensify competition, potentially driving down inference costs and accelerating model iteration speeds for the broader industry.
