Apple Retakes the Crown: Markets Flip on World's Biggest Company

In a single trading day, traders swapped NVIDIA and Apple's rankings entirely — Apple surged to 79% favorite for largest company honors while NVIDIA cratered to 22%, a mirror-image reversal across both the top and second-place contracts.

Markets executed a wholesale swap of the corporate pecking order Tuesday: Apple's odds of ending July as the world's largest company by market cap rocketed to 79%, up 56 points on the day and 50 over the week, while NVIDIA's cratered to just 22%, down an identical 56 points — the second-place contract flipped in perfect mirror image, NVIDIA now favored there at 77%. Geopolitical risk kept fading in parallel: Iran military action against a Gulf state fell to 4%, down 14 points on the day and 51 over the week, while an Israel-Iran ceasefire through July 31 firmed to 94%, up 7. In AI, the next Claude Opus's Arena-debut probability leapt to 95%, up 91 points in 24 hours — the sharpest move anywhere in today's data. In Rome, Roberto Mancini's odds of taking Italy's bench climbed further to 53%, up 18, as Andrea Pirlo's collapsed to 2%.
