X confirms algorithm now boosts posts read to the end for non-followers

ThePeterMick · x · 2026-10-29

X confirmed in its open-source algorithm changelog two changes live since early October: since Oct 8, ranking better predicts time spent per post; since Oct 13, the out-of-network discovery system favors posts people read all the way through. The author, who tracks the open-source algo daily with Claude, recaps current weights: likes at 0.66, 10+ seconds dwell worth 0.4, time-spent score up 50% this month; new posts get a push in the first 2 hours / 200 views (can land 16th in feed for sub-50K accounts); copy-link shares top the list at 20, replies/quotes/DM shares worth 5; a second original post in one feed only counts 62%. Takeaway: write posts people finish.
