Chip stocks’ weighting in the S&P 500 has risen to a record 19.7%, nearly quadrupling from 2020 levels, driven mainly by an artificial intelligence investment boom.
According to Odaily, as demand for AI infrastructure and computing power continues to expand, semiconductor shares have become one of the core drivers of the current U.S. stock market rise.
The report said the S&P 500’s composition has become more concentrated in a small number of leading technology and chip companies, while also increasing market concerns about excessive index concentration and elevated valuations.
Despite these concerns, continued inflows into related ETFs have supported the sector’s performance.
Market participants are closely watching whether AI capital expenditures can continue to materialize to support current semiconductor valuation levels.
