Prediction markets now price a 76.5% chance that NVIDIA will be the largest company in the world by market cap on July 31, a probability that has climbed 8.5 points in the last 24 hours on $47,494 in volume. The implied odds reflect a tight race: multiple market-cap trackers show NVIDIA's value clustered between $4.77 trillion and $4.94 trillion in July 2026, while Apple has hovered near $4.88 trillion. The lead has already changed hands at least once this month, with CNBC reporting on July 17 that Apple briefly overtook NVIDIA during intraday trading.
NVIDIA's market cap has shown meaningful volatility in recent weeks. Public.com recorded NVIDIA at about $4.77 trillion on July 7, while Capital.com and CompaniesMarketCap both reported figures near $4.94 trillion by July 9 and later in the month, respectively. TradingEconomics listed NVIDIA at roughly $4.78 trillion in July, underscoring how quickly the lead can shift. Apple's own valuation has remained competitive, and the two companies have traded places for the title of world's most valuable company within days.
The market closes on July 31 at 23:59 UTC, meaning the outcome depends on closing market caps rather than intraday leadership. Small moves in either stock could decide the result, as both companies are valued in the mid-$4 trillion range. NVIDIA's recent gains in prediction market probability suggest traders see a slight edge for the chipmaker, but the narrow gap leaves room for Apple to reclaim the top spot in the final sessions.
Investors are watching for any catalysts that could move either stock before the deadline, including earnings reports, product announcements, or broader market shifts. The tight race has drawn attention to the final trading days of July, with the outcome likely to be determined by the last bell. Whether NVIDIA holds its lead or Apple retakes the crown, the contest underscores the concentrated value at the top of global equity markets.
