Health coverage after losing my job: marketplace or Medicaid? - 10 weeks in

I have 12 weeks left on my current insurance and I am comparing options. I worked as an operations analyst before this. I think my income this year might qualify for a subsidy. How fast did coverage start?

Losing job-based coverage usually opens a special enrolment window, so check the deadline on the official marketplace site. I missed it by a day once and regretted it.
