xAI burned $6.4B last year; SpaceX IPO filing shows why spending is far from over

xAI去年亏损64亿美元--SpaceX的IPO文件揭示其支出远未停止的原因

SpaceX’s IPO filing disclosed that xAI lost $6.4 billion in 2025 and plans a large Grok expansion; the post does not disclose the expansion scale, capital spending, or financing terms.

Why it matters: HKR-H/K/R all pass: the $6.4B loss is a hard number, SpaceX’s IPO filing gives the story an unusual source, and xAI’s Grok expansion hits the burn-rate debate. Missing capex, scale, and financing keep it below 85.
