Curious what's happening in late September to drive predictions up

So I’m browsing ratings and price predictions to get a feel for how this works.

I’m seeing many price predictions are flat until around Sept 22, at which point they rise until Sept 28.

Just wondering what’s driving that prediction.

Price predictions are based on historical pricing data, therefore at a similar time in crypto history (likely 2017) the market had a period of a few days of normalcy then went back up.
