I say nearly all because there are still three numbers missing:
Vermont has yet to release any 2019 enrollment data. This is the 3rd year in a row that they've been radio silent. Assuming they're close to last year (28,763 QHP selections), they should add around 28,000 to the national total.
New York still has 2 days left for people to #GetCovered. I'm going to assume they'll tack on perhaps 5,000 more people today and tomorrow.
The District of Columbia hasn't posted any updates since December 11th, which means not only do they still have 2 days for people to sign up, they're actually missing a whopping 51 days worth of enrollment data. Again, assuming they wrap up close to last year, that should mean another 1,400 or so from DC.
Between the three, I'd expect another ~34,000 QHP selections to be tacked onto the totals below.
