I thought it would behave like you expected – always create a subdir for 
each ZIP. I could reproduce that it does not. So I looked at Ark’s settings: 
there is an option to create a subdirectory for a ZIP as soon as the zip 
contains more than one item. So it is still there, but not for every file.

Don’t give one-liners more credit than they’re due. All you need is a 
for-loop over all ZIP files, calculate an ouput dir by removing the trailing 
“.zip”, and finally call unzip with both:

for z in *.zip; do unzip "$z" -d "${z%.zip}"; done

If you want to be smart, omit the extraction if the output directory already 
exists, to avoid overwriting stuff:

# for-loop:        cut off ".zip"  does dir exist? yes                   no
for z in *.zip; do d="${z%.zip}";  [ -d "$d" ] &&  echo "Skipping $z" || unzip "$z" -d "$d"; done
