US stock futures remained flat Tuesday evening as investors took positions ahead of Nvidia's earnings report and President Trump's State of the Union address. The cautious mood followed a positive session on Wall Street where technology stocks rebounded from recent losses amid easing AI sector concerns. S&P 500 futures steadied at 6,902.50 points while Nasdaq 100 futures held at 25,031.0 points.

Trump prepares to deliver his address at 21:00 ET amid ongoing uncertainty about his tariff plans after the Supreme Court struck down most of his trade agenda. The president implemented a 10% import tariff after the ruling, though lower than the initially threatened 15%. The address comes with polling showing only 39% approval of his job performance so far. Wall Street indexes rose 0.8-1.1% Tuesday on tech recovery.

Market attention shifts to Nvidia's quarterly report due Wednesday after the close. The chip giant is expected to post earnings per share of $1.52 on revenue of $65.56 billion, substantially higher than a year ago. The print will serve as a bellwether for the AI industry and chip demand. AMD surged nearly 9% earlier on a major supply deal with Meta, while HP Inc and Workday Inc fell 6.1% and 8% respectively on disappointing outlooks.
