Nvidia and Apple together account for more than 15% of the S&P 500—the highest concentration since the dot‑com era—driving market focus on AI and bond‑yield
Nvidia and Apple together represent just over 15% of the S&P 500, the highest two‑stock weighting ever recorded and well above the peak seen during the late‑1990s dot‑com bubble【1】.

| Combined S&P 500 weighting | >15% |

| April CPI YoY inflation | 3.8% (upside surprise) |
| 10‑year Treasury yield | 4.61%, 12‑month high |
Creative Planning’s chief markets strategist Charlie Bilello highlighted the new chart showing Nvidia (NVDA) and Apple (AAPL) together accounting for more than 15% of the S&P 500, a level that eclipses the Microsoft‑GE dominance of the dot‑com bubble【1】. The surge reflects investor belief that artificial‑intelligence breakthroughs will translate into outsized earnings for both firms—Nvidia on its AI‑chip demand and Apple on the AI initiatives expected from incoming CEO John Ternus.
Mid‑May market turbulence was sparked by an unexpected rise in the April Consumer Price Index, which showed annual inflation at 3.8%—higher than analysts had forecast and driven largely by oil price spikes linked to the Iran conflict【1】. The higher‑than‑expected CPI dampened hopes for imminent Federal Reserve rate cuts, prompting a rapid sell‑off in Treasury bonds and pushing the 10‑year yield to 4.61%, its highest level in a year【1】. Rising yields compress the present value of high‑growth tech stocks, prompting institutional investors to trim exposure ahead of upcoming megacap earnings, with notable pullbacks seen in other high‑fliers such as Micron and Sandisk【1】.
The unprecedented weighting of Nvidia and Apple underscores how AI expectations have reshaped market dynamics, but the recent yield surge suggests that even the most dominant tech names are vulnerable to macro‑driven valuation pressures. The next data points will determine whether the concentration tightens further or begins to unwind.
