Follow this steps;

convert your text file to points
convert points to lines with Points to Line
convert lines to polygons with Feature to Polygon (Advanced licnese required)

Or You can Use arcpy - no specific license required.

See an example at the bottom of the page Writing geometries. The code converts a list of coordinates (a text file can be regarded as such a list) into polylines, you can easily modify it to create polygons.

I found this on this link;
