Unless you lump all protestants together it is by a lot at least according to the first link I found. They make up a little over a quarter of American Christians.
It is, by a pretty wide margin. While many more people identify as Protestant, they’re split among dozens of denominations. I haven’t seen recent stats but in 2015 they were about 20% of the US. For comparison, the Southern Baptist Convention was the second largest at about 5.3%
