SpaceX Now Owns xAI: What It Means for Your Grok Data (2026)
xAI became a SpaceX subsidiary in a $1.25 trillion deal, and X's terms now treat your Grok prompts the same as public posts. Here's what actually changed.
If you use Grok, two changes in the past six months are worth understanding — not because either one is secret, but because both are the kind of fine-print shift that's easy to miss until you're trying to figure out where your data actually ends up.
On February 2, 2026, SpaceX acquired xAI in an all-stock deal valued at $1.25 trillion, making Grok — and by extension X — part of the SpaceX corporate structure. Separately, on January 15, 2026, X updated its terms of service to expand the definition of "Content" to explicitly include your Grok prompts, inputs, and outputs. Here's what both of these actually mean for your conversations.
Your Grok Prompts Are Now Treated Like Public Posts
Before January 2026, X's terms of service focused primarily on what you posted publicly on the platform. The updated terms broadened the definition of "Content" to also cover what you type into Grok — your prompts, and the responses Grok gives you.
In practical terms, this means your conversations with Grok now fall under the same terms that govern your public X posts, rather than being treated as a separate, more private category of interaction. If you're a heavy X user who's already accepted those terms for your posts, this may not change much for you in practice. But if you primarily use Grok as a standalone AI assistant, it's worth knowing that your prompts are now covered by the same broad content terms as anything you've publicly posted.
This is on top of what was already true: by default, xAI uses your Grok conversations to help train its models (covered in detail in our guide on whether Grok trains on your data), and you have to actively opt out via Settings if you don't want that.
What the SpaceX Acquisition Changes (and Doesn't)
The $1.25 trillion all-stock deal folded xAI — and therefore Grok — into SpaceX as a subsidiary. A few things are worth being clear about:
- This is a corporate ownership change, not (as far as has been disclosed) an immediate change to Grok's privacy policy. xAI's privacy policy, last updated July 2025, remains the operative document as of this writing.
- Data governance across a larger combined entity is less predictable. Your Grok data doesn't sit with a single, narrowly-focused AI company anymore — it sits inside a combined SpaceX/xAI/X structure that has been reported to be preparing for a public offering. How data may move or be shared across that structure over time isn't something users have visibility into yet.
- xAI's separation from X's own privacy policy remains technically intact. If you use Grok through X (via the X app or website), X's privacy policy governs that interaction rather than xAI's standalone policy — a distinction that already existed before the acquisition, but is worth restating given the ownership change.
None of this means anything alarming is happening to your data today. It does mean the entity responsible for your Grok conversations is larger, more complex, and — like any company mid-restructuring — more likely to see further policy changes as things settle.
What Hasn't Changed
To be clear about the boundaries here: xAI's core data practices — what it collects, the ability to opt out of training use, and the lack of an official recently-deleted recovery window — remain as they were before both of these developments.

Why This Is a Good Reason to Keep Your Own Copy
Whatever happens next with Grok's ownership structure or terms, the fact remains: your conversation history exists only inside xAI/X's systems unless you export it yourself. As we've seen with Grok's own removal of its "Recently Deleted" recovery window, and now with two policy-adjacent changes in the space of a few months, relying on a single company's current settings to protect your history isn't a strategy — it's a bet.
AI Chat Importer imports your Grok export (along with ChatGPT, Claude, and DeepSeek) into a local, searchable archive on your own device. Nothing is uploaded anywhere — your data stays under your control regardless of what X, xAI, or SpaceX changes next.
Get the Desktop App — £29 one-time and keep a permanent, offline, searchable copy of your Grok history — independent of ownership changes, terms updates, or policy shifts.

FAQ
Does the SpaceX acquisition mean my Grok data is now shared with SpaceX? There's no confirmed policy change stating that Grok conversation data is now shared with SpaceX specifically. The acquisition changes corporate ownership; xAI's privacy policy, as of this writing, remains the operative document for how Grok data is handled.
What does it mean that my Grok prompts are treated as "Content" under X's terms? It means your Grok prompts, inputs, and outputs now fall under the same terms of service that govern public X posts, rather than being treated separately. This is a terms-of-service classification, not necessarily a change to what data is collected.
Does this affect Grok used through the standalone app, or only through X? The January 2026 terms update applies to X's terms of service. If you use Grok via X, this is directly relevant. Grok accessed through the standalone Grok app or grok.com is governed by xAI's separate privacy policy, though the broader ownership change under SpaceX applies regardless of which interface you use.
How do I back up my Grok conversations so I'm not dependent on these policies? Export your Grok data periodically using X's or xAI's export tools, and keep the export somewhere under your own control. See our step-by-step Grok export guide, or use AI Chat Importer Desktop to automatically organize and search your exports locally.
