Apple shares closed at $341.07 on September 25, 2026, near the upper end of their recent $335–$345 trading range following the iPhone 18 launch and the September 1 CEO transition to John Ternus. The evenly distributed Polymarket odds across $320–$365 bins reflect high near-term uncertainty, driven by strong iPhone demand signals offset by persistent margin pressures from rising memory and component costs, elevated valuation near 39 times trailing earnings, and limited catalysts before the October 29 earnings release. Broader equity momentum, Treasury yields, and any incremental supply-chain or China-related updates this week will likely determine whether the stock holds near current levels or shifts within the contested ranges.
