New Placements Are Always Cheapest At The Start
Every time Meta opens a fresh placement, the same pattern shows up. Few advertisers bid on it, so the auction is soft, and CPMs sit lower than Instagram or Facebook.
Threads is in that early window now. Meta has been rolling it out globally as a real ad placement inside the standard scheme.
This is not a permanent discount. As more advertisers flip the placement on, competition climbs and the price drifts toward everything else. The cheap part is a function of being early, not a feature of the platform.
