Trader consensus on Polymarket has coalesced around Apple as the second-largest company by market capitalization at March 31, 2026, close, with a 100% implied probability reflecting its $3.73 trillion valuation—firmly behind NVIDIA's $4.24 trillion lead but ahead of Alphabet's $3.46 trillion and Microsoft's $2.70 trillion. This positioning stems from NVIDIA's sustained AI chip dominance driving its top spot, while Apple's resilient services revenue growth and iPhone ecosystem stability have maintained its runner-up status amid volatile tech sector rotations over the past month. Strong capital inflows underscore the wisdom of crowds, though rare tail risks like after-hours surges in challengers or data revisions could theoretically shift rankings before final confirmation.
