Grok is xAI’s assistant, built directly into X, and that distribution gives it real influence.

According to SpaceX’s May 2026 S-1 filing, 117 million people use Grok’s features every month, out of X’s 550 million monthly active users. That makes it one of the most-used AI assistants on the planet, and a growing influence on how people discover information. So the sources Grok leans on are actively shaping what hundreds of millions of users read.

To see which sites those are, we tracked every domain Grok cited across a broad set of US queries, then ranked them by mention share — each domain’s slice of all the citations that the top sources collectively earn. The leader is www.reddit.com, capturing 16.3% of citations.

Ahrefs’ Brand Radar, which tracks the responses AI platforms give to a large, search-backed set of real user queries. For this article, we looked at every domain Grok cited across over 1.9 million US queries spanning all topics, then counted how often each domain appeared as a source.

For each website we report:

  • Mention share — a domain’s citations as a percentage of the summed citations of the top 50 most-cited sources. It shows how much of Grok’s “source attention” each website captures.
  • vs last month — how the domain’s rank has moved since the previous monthly snapshot (▲ climbed, ▼ fell, or NEW if it wasn’t in last month’s top 50).
  • Pages cited — the number of distinct pages on the domain that Grok cited, a measure of how broadly the site is referenced rather than how often.
  • DR (Domain Rating) — Ahrefs’ 0–100 measure of a website’s backlink-profile strength, included for context on each source’s overall authority.

This article is generated and automatically kept up to date every month by Agent A, our AI agent. Each month it pulls the latest Brand Radar data, recalculates mention share and rank movement, and refreshes the chart and table above — so the figures always reflect the most recent snapshot.
