Monster Energy is halal by ingredient — the taurine is synthetic (not from animals), and standard flavours contain no alcohol or animal-derived ingredients. We say "depends" rather than a flat yes because not every Monster variant is certified and the large flavour range can vary; the classic Green and Zero Ultra are the most widely accepted. Some Coca-Cola-distributed Monster lines carry a halal mark abroad.

The short version
Monster is halal by ingredient — synthetic taurine, no alcohol, no animal ingredients. The "depends" is about certification and the sheer number of variants.
The taurine myth
The most common worry is that taurine comes from bulls. It does not — the taurine in Monster is synthetically produced in a laboratory, so it is not an animal-source concern.
Why "depends"
Standard Monster flavours (Green, Zero Ultra) are widely accepted as halal by ingredient. But Monster has a very large and changing flavour range, and most are not formally certified in the US, so a blanket "yes" would overstate it. Some Monster lines distributed by Coca-Cola carry a halal mark in certain markets.
