Shadowrocket's sustained dominance as the top paid app in the US App Store stems from its position as an affordable, one-time $2.99 rule-based proxy utility that delivers granular traffic routing, broad protocol support including V2Ray, Trojan, and Hysteria, plus features like ad blocking and HTTPS decryption for power users. Traders see this as creating steady organic demand that has kept it atop paid charts for weeks with no comparable rival releases or marketing pushes to displace it. With resolution on September 11 only days away, the 95.5% market-implied odds reflect this structural lead, though an unexpected competitor update or seasonal sales spike could theoretically narrow the gap if it drives outsized volume in the interim.
