**Apple holds a near-certain position as the second-largest company by market capitalization at the end of August 2026.** As of August 31, NVIDIA leads at roughly $5.27 trillion thanks to sustained AI chip demand, while Apple sits firmly at approximately $4.7 trillion—well ahead of Alphabet (~$4.16T) and Microsoft (~$3.79T). Traders assign Apple 100% implied probability because its market cap has shown resilience through recent volatility, bolstered by strong services revenue, iPhone ecosystem lock-in, and incremental AI features in hardware and software. The market closes today with minimal session time remaining, leaving little room for reversals. Realistic challenges remain narrow: an unprecedented intraday surge in a competitor like Alphabet or Microsoft could theoretically close the gap, but historical patterns and current spreads make this improbable without extraordinary news. The skin-in-the-game consensus in prediction markets reflects this stability, though tech valuations can shift quickly on macro or sector-specific catalysts.
