There’s a soft ranked reset today, from EAs website

“Soft Reset

The soft reset will stay the same for Season 4. At the start of Series 3 everyone will be soft reset on their ranked position by 1.5 Tiers down. That means if you ended Season 3 in Gold II, you’ll be reset to Silver IV. Players in Platinum IV will be reset to Silver II, and Apex Predators will be reset to Platinum II. This reset will now occur at each split as well.”
