The wealth gap in America has soared to a historic high, with the country's richest consumers showing a significant divide from the rest of the population attributed to market speculation, notably the recent boom in "runaway AI stocks." Moody's Analytics Chief Economist Mark Zandi noted this trend is leading to a more pronounced K-shaped economy. Economic data analysis from last week indicated that in the third quarter of 2025, households making over $175,000 annually, representing the top 20% of income earners, contributed almost 60% of all personal spending. This marks a record peak since 1989. As depicted in the chart, the spending capacity of the top 20% (green line) has surged while the bottom 80% (blue line) has declined, shaping a clear "K" pattern in the nation's consumption trends. The K-shaped economy continues on a trajectory toward further inequality.
