(Reuters) - U.S. index futures were muted on Tuesday, as investors refrained from placing big bets before AI chip leader Nvidia's earnings this week and amid policy caution from Federal Reserve officials ahead of the central bank's meeting minutes.

Rate-setters have offered few clues on the timing for rate cuts this year and several Fed officials on Monday refrained from noting inflation moderating to the 2% target despite recent data pointing to easing consumer price pressures.

That weighed on market sentiment, with investors now awaiting remarks during the day from officials including Christopher Waller, Thomas Barkin, Raphael Bostic and Michael Barr ahead of the Fed's latest policy meeting minutes on Wednesday.

Technology stocks kicked off the week on a strong note, driving the tech-heavy Nasdaq to its highest closing level on Monday while the S&P 500 inched closer to its all-time high hit last week.

Nvidia's quarterly earnings on Wednesday are also in focus, likely to be a significant market trigger and a litmus test for the success of the generative AI boom.

Data from options analytics firm Trade Alert showed Nvidia's options are primed for an 8.7% swing in either direction by Friday, translating to a market cap swing of $200 billion.

"In Nvidia's case, the confidence around the artificial intelligence boom is more than just hype... It has real substance," said Derren Nathan, head of equity research, Hargreaves Lansdown
