Grok's downloads have decreased significantly, dropping to approximately 8.3 million in April this year from over 20 million in January. According to NS3.AI, this decline is attributed to Grok's AI model lagging behind faster-growing competitors. Recon Analytics reported that Grok's paid-user share in the second quarter of 2026 was 0.174%, showing minimal change from 0.173% a year earlier. Additionally, a computing lease between SpaceX and Anthropic has raised further concerns about Grok's ability to keep pace with its rivals.
