Prime Day check-in: Is ChatGPT really changing how people shop?

By RealityMine — powered by MFour’s U.S. consumer network. RealityMine captured in-the-moment app behavior around Prime Day to see which apps people use before Amazon—and what happens once they’re there.

Highlights

  • Prime Day behaved like Prime Day: Amazon saw +21% visitors, +44% searches, +33% buyers, +43% purchases vs. the prior week.
  • ChatGPT is growing, not the launchpad: 9.1% of shoppers used ChatGPT; only 1.5% did so in the 5 minutes before Amazon.
  • When ChatGPT appears, intent lifts: Amazon conversion 9.4% (vs. 7.1% overall) when ChatGPT shows up within 30 minutes.
  • Discovery stays classic: Google leads; Pinterest (~4×), eBay (2.6×), Target (2.4×) show stronger pre-Amazon linkage than ChatGPT.
