A defining characteristic of the Dow is that it's a price-weighted index. That means a stock's significance is based on its price and not the market cap of the company. In getting trounced by Nvidia in artificial intelligence while also losing share of its core PC and data center processor market, Intel has seen its stock price plummet by more than half this year, closing on Friday at $23.20.
Now, Intel is by far the least-significant member of the Dow, with a weighting of less than 0.5%. The next lowest-priced stock is Verizon at around $41. With Intel being the only chipmaker in the index, the sector is underrepresented relative to its position in the economy.
