Elon Musk's artificial intelligence model, Grok, is reportedly lagging behind its rapidly growing competitors. According to Odaily, a significant computing power leasing agreement between its parent company, SpaceX, and Anthropic has raised questions about Grok's ability to catch up with industry leaders. Since its launch two years ago, Grok has attracted millions of users through its integration with Musk's social platform X and features like the controversial 'AI Companion.' However, recent data indicates that its growth momentum has stalled. Analysis from AppMagic reveals that Grok's downloads dropped to approximately 8.3 million in April this year, down from over 20 million in January. A survey conducted by research firm Recon Analytics, involving over 260,000 U.S. AI users and professionals, shows that the percentage of respondents willing to pay for Grok remained nearly unchanged at 0.174% in the second quarter of 2026, compared to 0.173% a year earlier. In contrast, more than 6% of respondents reported having paid for ChatGPT.
