Grok Bot subscribers reported exhausting their weekly usage limits days before scheduled resets over Halloween weekend. Some said their meters reached 100% overnight despite little apparent activity. Elon Musk acknowledged the cost pressure on Nov. 1, writing that serving the AI agent had become “unsustainably high relative to revenue.”
- Grok Bot subscribers exhaust weekly usage allowances days before scheduled resets, triggering unexpected service limits across all paid tiers.
- Elon Musk acknowledges Grok Bot inference and compute expenses became unsustainably high relative to subscription revenue.
- The product scaled to 800,000 paid weekly users by early October, straining shared compute allocations across SpaceX's Super Intelligence infrastructure.
Users Report Weekly Limits Exhausted Ahead of Schedule
Grok Bot is an AI agent designed to carry out tasks through computer interfaces rather than simply respond to prompts. That capability can involve sustained model activity beyond a single exchange, although the reported meter jumps do not establish how much background execution contributed to the complaints.
One subscriber reported a weekly meter jumping from the mid-50% range to full overnight. Another said the allowance was exhausted four days before its reset. The accounts document what users experienced, but not what consumed their allowances. Musk described the restriction as “just being sensible” and raised the question of whether higher-tier pricing was too steep.
Grok Bot’s Growth Has Raised the Cost of Serving It
Grok Bot’s subscriber base expanded rapidly before the restrictions surfaced. SpaceX President Gwynne Shotwell said on the company’s Oct. 20 earnings call that the product had about 800,000 paid weekly users in early October, more than twice the previous month’s level.
Musk has described Grok Bot as one of the fastest-growing products he has seen. A larger customer base can increase serving costs, while longer or more frequent agent workflows can push them higher. The available figures do not isolate how much of Grok Bot’s cost growth came from either factor.

Grok Bot Draws From a Shared Usage Pool
Under The X Subscription, Grok Bot draws from a shared weekly pool covering Grok, Grok Bot and supported Cursor model activity. Premium costs $30 a month, Super $100 and Ultra $200, with larger included usage pools at higher tiers.
The pool is not measured in a fixed number of completed agent tasks. Usage depends partly on the models and activity involved, making a subscription difficult to translate into a predictable task count. Two subscribers on the same tier may use different amounts of their pool depending on the models and workflows they run.
That structure leaves a central question unanswered: whether the early exhaustion reports reflect revised allowances, different consumption patterns or an adjustment to how usage is measured.
SpaceX’s AI Infrastructure Business Is Expanding
SpaceX reported $7.56 billion in third-quarter 2026 revenue for its Super Intelligence segment, alongside $431 million in operating income. The segment accounted for about 52% of the company’s $14.6 billion in total revenue. Its revenue also exceeded Connectivity, the segment that includes Starlink.
The company reported $6.7 billion of incremental Super Intelligence solutions and infrastructure revenue year over year, driven by cloud services agreements, the Cursor acquisition and growth in its models and software applications. Nameplate computing capacity reached 1.7 gigawatts by Sept. 30.
The figures show the scale of SpaceX’s AI infrastructure business, but they do not represent compute-rental revenue alone. Nor do they identify how much capacity was assigned to Grok Bot or whether outside customers received computing capacity previously reserved for the agent.
SpaceX has not published the old and new weekly caps, the cost of a typical agent session or a breakdown of Grok Bot’s computing consumption by subscription tier. It also has not explained whether the reported meter jumps reflected background execution, revised accounting, a dashboard issue or a reduction in available usage.
Musk’s cost admission is clear. What changed in the usage limits, and whether capacity allocation played a role, remain unanswered. Subscribers can see where their meters stop. They still cannot see exactly why.
