The Institute of Supply Management and Markit Economics will release their monthly reports on US manufacturing on Thursday.
The ISM purchasing manager's index (PMI) is forecast to improve to 52.5 from 51.9 for November. Regional data received over the past month suggested improvement in the sector and pointed to a strong report, Nomura economists said in a note.
However, low oil prices and the strong dollar still challenge US manufacturers and their ability to compete well globally.
Markit reported its index at 53.9 in a preliminary report. Many manufacturers told the firm that clients were more willing to spend with the uncertainty over the election over.
