SuperGrok payers with another paid AI were more likely to show a later Grok receipt
Share of an established August 2025–February 2026 cohort with a Grok receipt from June 18–August 17, 2026
Share with a later Grok receipt
Source: YipitData U.S. e-receipt panel. SuperGrok payers with ChatGPT, Claude, or Perplexity n=1,368; solo SuperGrok payers n=1,876. X Premium was excluded. Receipt capture affects absolute levels, so the relative comparison is more reliable.

Share of SuperGrok payers
Source: YipitData U.S. e-receipt panel. Measured competitors were ChatGPT, Claude, and Perplexity. Gemini and X Premium were excluded, so the share with another paid AI is a conservative floor.

How often did SuperGrok and ChatGPT payers also pay for the other service?
Among SuperGrok payers, 36.7% also paid ChatGPT, while 4.9% of ChatGPT payers also paid SuperGrok. The roughly 7.5× difference reflects the two services’ different subscriber bases; it does not show which assistant was primary or whether one caused the other subscription.
Assumptions & Methodologies
We analyzed U.S. e-receipts for paid SuperGrok across Apple, Google Play, and direct billing, excluding X Premium. The overlap window contained 9,688 payers from August 18, 2025–August 17, 2026. The later-receipt cohort established whether users paid another measured AI or only SuperGrok from August 2025–February 2026 and checked for a Grok receipt from June 18–August 17, 2026. Competitors were ChatGPT, Claude, and Perplexity; Gemini was unavailable. Receipts show billing, not usage, and capture may favor users with more visible subscriptions. Both groups used identical measurement, but the association does not establish that paying multiple services caused persistence.
