Taylor Swift’s “I Knew It, I Knew You,” the lead single from the Toy Story 5 soundtrack, drives the market’s near-certain outcome for the Billboard Hot 100 dated June 20. The track posted record-breaking streaming numbers, strong radio airplay, and robust sales upon release, powering a debut at No. 1 that aligns with the film’s June 19 theatrical rollout and Swift’s established chart dominance. Traders see little room for challengers like Song J or Olivia Rodrigo’s “The Cure,” which launched weeks earlier and lacks comparable momentum. An upset would require an unforeseen late-week surge in consumption data or a major promotional push from competitors, though current tracking makes such shifts improbable before the chart finalizes.
