Trader consensus crowns NCAA March Madness Live as the frontrunner at 67.5% implied probability for #1 free US Apple App Store spot on March 20, fueled by explosive bracket hype following Selection Sunday on March 17 and first-round games tipping off March 21. Historical tournament surges routinely vault the official NCAA app to the top amid fan frenzy for live scores and streams, outpacing ChatGPT's steady 27.5% hold buoyed by AI cultural dominance but no matching event catalyst. CBS Sports App at 2.5% gains minor traction as a scores companion, while fringe bets like Claude (1.1%) and Freecash (1.1%) fade against basketball mania; traders eye evening download spikes pre-tipoff for final shifts.
