Wall Street futures flat ahead of Nvidia earnings and PCE inflation data

Wall Street futures were little changed Wednesday ahead of Nvidia's quarterly earnings and the Federal Reserve's preferred inflation gauge, with S&P 500 and Nasdaq 100 futures dipping about 0.1% and 0.25%. Nvidia is expected to report quarterly revenue near $92-93 billion, roughly double year-ago levels, with adjusted earnings per share around $2.09. Investors are focused on forward guidance and margins, as analysts note earnings surprises carry less weight than evidence of sustained hyperscaler capital spending. The July PCE inflation report, due at 8:30 am ET, is forecast to show 0.1% monthly headline and 3.6% annual growth. Intuit fell over 11% premarket on slower revenue growth forecasts, while Zoom dropped 5% on weak outlook, highlighting pressure on traditional software firms versus semiconductor gains.
