Unprecedented Market Cap Concentration

On Wednesday, in a post on X, The Kobeissi Letter highlighted that Nvidia “has reflected 8% of the S&P 500’s market cap on average in 2025, the highest percentage of any company in the index.”

“It has surpassed Apple, $AAPL, which held the top spot for the previous 6 consecutive years,” after the chipmaker edged out the Cupertino-based giant to become the most valuable company in the world, around the same period last year.

“Nvidia's market weight is now the largest for any company since 1974,” the post said, highlighting IBM Inc. (NYSE:IBM) as the previous holder of this title, having “dominated the market for 15 years through the 1970s and 1980s,” after General Motors Co. (NYSE:GM) did the same “for 18 years during the 1950s–1970s.”
