All three main U.S. indexes hit fresh record closing highs in the previous session as chip stocks rallied after Micron Technology's upbeat forecast and the Fed signaled it was still on track for three interest-rate cuts this year.

Traders now see a 74% chance of the first rate cut hitting in June, from 56% at the start of this week, according to the CME's FedWatch Tool.

Investors will be closely monitoring commentary from a host of central bankers expected later in the day, including Fed Chair Jerome Powell, for further cues on the central bank's monetary policy trajectory.

At 05:02 a.m. ET, Dow e-minis were up 18 points, or 0.04%, S&P 500 e-minis were up 5.75 points, or 0.11%, and Nasdaq 100 e-minis were up 32.75 points, or 0.18%.
