Narrative:

After receiving our clearance from ground control to taxi for departure; we were instructed to taxi but to hold short of [the] runway. As we were making a right turn; I noticed a fast approaching A330 off my left. I verbalized that I was stopping the aircraft to my first officer; and to my disbelief; I saw the A330 right wing miss us by approximately 30 to 40 ft. The radio congestion was such that we were unable to query ground control as to the sequence. After the A330 narrowly missed us; I eventually interjected on the frequency 'hey ground; that [A330] just cut us off!'. We didn't immediately receive an answer; but then another controller came on the frequency and later apologized for the incident.
