Apple maintains its position as the third-largest company by market capitalization, currently exceeding $4 trillion, as Nvidia and Alphabet hold the top two spots driven by sustained AI demand for semiconductors and search-advertising strength. With only two weeks remaining until the end of May, the absence of major earnings releases or regulatory shifts for these mega-caps has reinforced trader consensus around Apple's stability, bolstered by resilient services revenue and limited downside volatility in recent sessions. Market-implied odds reflect this high-probability outcome backed by real capital commitments. A sharp near-term rally in Microsoft or Amazon share prices, or an unexpected decline in Apple's valuation below key peers, represents the primary scenarios that could alter the ranking before month-end resolution.
