Prediction Markets Favor Nvidia to Stay on Top Despite Apple's Charge
Prediction markets on Polymarket favor Nvidia to end July as the world's most valuable company, with a 70% probability, despite a recent wobble that briefly cost it the crown to Apple. Apple, valued at about $4.8 trillion, overtook Nvidia's $4.92 trillion during Friday trading, reclaiming the top spot for the first time since April 2025. Nvidia's odds have slid 18 points as a sell-off in semiconductor and AI stocks reshuffled rankings, driven by investor doubts over AI infrastructure spending. Apple has been the standout Magnificent Seven performer this year, up over 22%, aided by its redesigned Siri and relatively light AI spending. The contest remains close, with barely $1 trillion separating the two companies at times. Polymarket contract volumes have topped $3.1 million, highlighting interest in the rivalry symbolizing the AI valuation debate.
