My internet didn't fully load Madara's but from what I saw that was the ten-tails eye but red. Madara's Mangekyo's different and also the guy in the gif was the sage of the six paths.
If you can answer me all this with a spoiler from the manga, then don't.
Edit: I reloaded site and it did load Madara's now but my doubts remain. All gifs are pretty cool anyway.
