SpaceXAI launches Grok 4.5 model and leverages IPO stock for acquisitions

SpaceXAI and Cursor released the Grok 4.5 AI model on July 8, 2026, targeting coding, research, and complex business tasks. The model is designed for multi‑step autonomous workflows, handling software engineering, data analysis, legal work and office tasks from a single prompt. It operates at about 80 tokens per second, uses fewer output tokens than competing models, and is priced at $6 per million output tokens and $2 per million input tokens, positioning it as a cost‑effective option for enterprise AI agents.

In parallel, SpaceX’s recent public listing created a new acquisition currency. In April 2026 the company signed a $60 billion agreement to acquire the AI coding firm Cursor using SpaceX stock, with a $10 billion cash breakup fee if the stock deal fell through. The IPO supplied roughly $53 million in cash and enabled the company to secure investment‑grade credit ratings, but most new acquisitions are paid in stock, preserving cash while providing liquidity to private sellers.
