US stock futures were mixed as Americans went to the polls for the midterm elections and braced for more AI industry earnings from Advanced Micro Devices (AMD).

Futures on the Dow Jones Industrial Average ( YM=F ) fell 0.8%, while those on the S&P 500 ( ES=F ) dropped 0.2%. Contracts for the Nasdaq-100 ( NQ=F ) rose 0.1% following a turbulent day for chip stocks.

This evening, investors will watch the election results and ballot initiatives for insights into potential policy changes on key issues affecting markets, including pharmaceuticals, the housing market, and AI data centers.

But before then, AMD will report earnings after the closing bell, giving investors another glimpse of AI demand at a precarious time for the artificial intelligence trade. As Intel's (INTC) stock demonstrated last week, the market's reaction is likely to depend as much on Q4 guidance as on the company's top- and bottom-line results in the most recent quarter.

Apple (AAPL) stock fell during premarket trading following its own earnings report, which showed several bright spots (iPhone sales) but also some misses (Greater China revenue). Palantir (PLTR) stock also fell post-earnings despite results that beat expectations.

While earnings season continues apace, the Labor Department will release its Job Openings and Labor Turnover Survey (JOLTS) report, providing details about the level of job openings, hires, and quits in the US.
