Grok, Elon Musk's artificial intelligence chatbot, is rapidly losing ground in the competitive AI market. Downloads fell to approximately 8.3 million in April 2026, down 59% from a peak of more than 20 million in January, according to analysis firm AppMagic. Meanwhile, adoption by paying users has stalled almost entirely, with only 0.174% of surveyed U.S. consumers and workers paying for Grok compared to over 6% paying for OpenAI's ChatGPT, according to research firm Recon Analytics.

Why Is Grok Falling So Far Behind Its Competitors?

The decline reflects a broader struggle for Grok to compete with established AI leaders. Despite launching in late 2023 with Musk's promise to make it "maximally truth-seeking" and less restrictive than competitors, the chatbot has failed to gain meaningful traction among both consumers and businesses. The contrast is stark: in a survey of about 500 business decision-makers, Enterprise Technology Research found that 48% of companies were using and planning to continue using Anthropic's Claude, up from 21% a year earlier, while only 7% were using Grok, up from just 4%.

Grok's early growth strategy relied heavily on controversial features. The January peak in downloads came after an update that allowed users to virtually undress people in photos, a feature that drew regulatory scrutiny when applied to images of minors and was subsequently limited. The company also invested in a sexualized AI companion feature that former employees said drove engagement, but these tactics appear to have reached their ceiling.

The most damaging blow may be SpaceX's decision to rent massive computing capacity to Anthropic, Grok's direct competitor. In early May 2026, SpaceX signed a deal giving Anthropic access to all the computing power at one of Musk's main data centers, the Colossus 1 facility near Memphis, Tennessee. This move signals that Musk is prioritizing revenue generation over Grok's competitive position, with analysts estimating the deal could bring SpaceX a few billion dollars annually.

How to Understand Grok's Position in the AI Market

• Consumer Adoption Gap: Grok's paid user base remains nearly flat at 0.174% of surveyed consumers, while ChatGPT commands over 6% and has achieved near-universal awareness, with more than three-quarters of survey respondents having heard of it by mid-2025.
• Enterprise Weakness: In the fastest-growing segment for AI revenue, coding assistants and enterprise tools, Grok is barely growing within organizations while Claude and Google's Gemini adoption is soaring, with Gemini reaching 40% of surveyed companies.
• Market Positioning: One tech investor compared Grok to "RC Cola" in a market dominated by "Coke" (OpenAI) and "Pepsi" (Anthropic), suggesting the chatbot lacks differentiation and consumer appeal.

The computing power deal with Anthropic represents a strategic pivot by Musk. Arnal Dayaratna, vice president of software development at research firm IDC, noted that the arrangement shows Musk is "beginning to turn Colossus into an external computing platform for major AI companies rather than only using the facility for internal model development". This shift is particularly significant given that Musk described xAI, his AI company, as "pretty small," "very small," and "the smallest of the AI companies" during his court case against OpenAI in late April.

"OpenAI is Coke, Anthropic is Pepsi and Grok is RC Cola. I never really saw people drinking it," said Ben Pouladian, an engineer and tech investor based in Los Angeles.

Musk's willingness to partner with Anthropic marks a dramatic reversal from his February 2025 stance, when he described the company's AI as "misanthropic and evil" on X. Tech investor Pouladian suggested the shift reflects pragmatism: "The enemy of my enemy is my friend, and it's also my compute partner".

Not all observers have written off Grok entirely. Guillermo Rauch, chief executive of Vercel, a hosting company for AI agents, cautioned against counting Musk out of the AI race, noting that developers often move quickly between models based on performance improvements. He expressed optimism that Musk's recent reorganization of his AI unit could strengthen its competitive position, stating that "once Elon focuses, which is what is happening right now, we see him perform very very well".

However, the data suggests Grok faces an uphill battle. With Musk facing pressure to show investors that his companies are profitable ahead of SpaceX's expected initial public offering, the decision to monetize computing capacity through Anthropic may take priority over Grok's development. The chatbot's inability to gain meaningful market share, combined with Musk's own public downplaying of xAI's size and significance, suggests that Grok may remain a secondary priority in his portfolio of companies.
