When Do NBA DFS Projections Update? (Stokastic Sims)

NBA DFS is a game of information, and the lineups that hold up on the night slates are usually built on the newest number at 9 p.m., not the best projection at 9 a.m. A starter gets ruled out during warmups, a backup's usage spikes, the field piles onto the obvious replacement, and the edge belongs to whoever saw all three move first. That is why "when do NBA DFS projections update?" is the most useful question a new Stokastic member asks, and it has a real answer.

Here is the short version, and then the feature that separates our data rhythm from a static optimizer: the numbers start moving early, they keep moving all day as news breaks, and in NBA the ownership projections keep updating even after lock. Hold onto that last part. It is the whole reason late swap works here, and we come back to it.

In Summary

• Point Projections Start Updating Early In The Day, earlier than most of the industry, so you get a real read before lineups lock.
• They Keep Refreshing Through Lock as injuries, confirmed lineups, and odds moves come in. Every Sims page carries a "last updated" stamp so you can see how fresh the numbers are.
• NBA Ownership Projections Keep Updating After Lock, which is what makes real late swap possible instead of guesswork.
• Re-Run The Sim When A Projection Or Your Contest Pool Size Changes — And Re-Run Your Late Swap When Ownership Updates After Lock. You Do Not Need To Re-Run For Your Own ROI Boosts, Exposure Caps, Or Filters (save those for the end).
• The Stokastic NBA Sims package puts every update — point projections and post-lock ownership — in one place.

When NBA DFS Projections Start Updating

A morning projection you never revisit is a missed edge. Stokastic runs point projections like a live wire: they begin updating early in the day, well before the slate locks, earlier than a lot of the industry. As we covered in office hours, we update point projections earlier in the day than a lot of sites and attach the stat details behind each number, so you can see the case behind it.

Why does an early read matter for a slate that locks at 7 p.m.? Because the early number is your baseline. When news hits at 6:45, you want to know how far a player moved from where he opened, not just where he landed. An early projection gives you that reference point, and the reference point is where leverage is born.

Projections Keep Updating As News Breaks

The early number is the start, not the finish. Through the day the projections keep refreshing on real events: a starter ruled out, a confirmed lineup, a late rest or load-management call, a line that moves on the game total. Each of those changes who sees minutes, and minutes are the engine of every NBA counting stat. Change the minutes and you change the projection, the value, and the ownership all at once.

This is also why one player's news is never one player's problem. News on one player does not just move that player: it shifts minutes and ownership across his whole team and ripples into the rest of the slate, a dynamic we walk through in the NBA DFS ownership video linked above. The replacement's projection climbs, the field chases him, and his ownership climbs with it. The Sims fold those effects into the updated numbers, so you re-run instead of redrawing the board by hand.

Every update is stamped. The Sims pages show a "last updated" time so you always know whether you are looking at this minute's numbers or an hour-old snapshot. That stamp is how you settle the two questions members ask most, "when's the next projections update?" and "will there be one more before lock?" It tells you exactly when the current numbers landed, so if a player's status just changed you can see whether the projection already caught it or the next refresh still has to. You watch the clock on the page instead of waiting on faith.

The Ownership Update That Makes Late Swap Work

Point projections updating all day is only part of the workflow. The part most of the industry does not do is this: in NBA, ownership projections keep updating after the early games lock.

That single feature is the difference between real late swap and a coin flip. Late swap means re-optimizing your remaining, unlocked lineup spots once early games are in the books. To do it well you have to grade those spots against what the field actually holds now, not against a pre-lock ownership guess that is already stale. As one of our staff put it in office hours, "I am not really sure how you can play late swap dfs with stale ownership projections." That is exactly the trap on tools that freeze ownership at lock.

The workflow is simple. When the early NBA games lock, open the late swap tool, load your entered lineups, and re-run. The sim re-grades your unlocked spots with current projections and post-lock ownership, so a swap you make at 9 p.m. is judged on 9 p.m. reality. It matters most in NBA, where late news like a rest call, an injury update, or a confirmed lineup change can swing the back half of the slate hard.

Do You Need To Re-Run The Sim When Numbers Update?

Fresh numbers are only useful if the sim actually reflects them, and that raises the practical question members ask right after "when do projections update?" The answer depends entirely on what changed. Some updates flow through the whole build and demand a re-run. Others are your own tweaks and can wait.

What Changed	Re-run the sim?
Point Projection Update	Yes
Ownership Update (GPP / Late Swap)	Yes
Contest Pool Size Change	Yes
Your ROI Boost On A Player	No
An Exposure Cap You Set	No
Filtering Or Narrowing Your Player Pool	No

The row people get wrong is the ROI boost. Because a projection change and a boost both push a player's exposure, it feels like both should trigger a rebuild. They should not. A new projection or a different pool size changes the inputs the whole simulation depends on, so everything downstream has to run again. Your ROI boosts, caps, and filters are adjustments you layer on top of a finished run, so make them last, once you are close to final, and you will not redo the same work after every refresh. The rule of thumb we lean on: change the projection and re-run only when you flat-out disagree with our median; save the boosts and caps for the end.

Quick tip: Build your player pool with ROI boosts (down to fade, up to force) rather than deleting players. That keeps the simulated field realistic while your exposures move, so a projection refresh does not force you to redo them.

How To Read The "Last Updated" Stamp

Treat the stamp as your freshness gate before you lock anything in. If a player's status just changed on the injury report, glance at the stamp: a time after that news means the projection already reflects it, and a time before means the next refresh is still coming. During the busy pre-lock window the numbers move fast, so the honest move on a close call is to wait for the stamp to tick past the news rather than lock on an hour-old value. The same stamp answers the early-slate question too: if you are looking for an ownership read on the early games, check that the ownership number updated after the last lineup news, not before it.

Frequently Asked Questions

When is the next NBA projections update? There is no single fixed clock; projections update through the day as news breaks. The "last updated" stamp on each Sims page tells you when the current numbers landed, and if a player's status just changed, the next refresh will carry it.

Will there be one more projections update before lock? There is no single fixed clock. Projections update through lock as news breaks, which is why the numbers you see right before tip can differ from the morning read, so check the "last updated" stamp before you finalize.

Will there be an ownership update for the early slate? Ownership updates through the day like the point projections, and in NBA it keeps updating after lock for late swap. For an early-games ownership read, confirm the stamp is later than the most recent lineup news.

Do I have to re-run the sim after every update? Only when a projection, an ownership number, or your contest pool size changes. Your own ROI boosts, exposure caps, and stack filters do not require a re-run, so apply those at the end.

Why did my player's ownership jump so much on one piece of news? Because news reshuffles minutes and usage across the slate, not just for the injured player. The obvious replacement gets chased by the field, and the Sims re-run that ripple so your build reflects it.

Play The Slate On Live Numbers

The thread that runs through all of this is a single idea: in NBA DFS, the freshest number gives you the edge, and a projection is only as good as the last time it moved. Stokastic starts the point projections early, keeps them refreshing as news breaks, and keeps ownership updating after lock — which most of the industry does not do — so your late swaps run on live reality instead of a pre-lock snapshot. The "last updated" stamp is there so you never have to guess which one you are holding.

Run your NBA lineups on numbers that keep updating through the slate. The Stokastic NBA Sims refresh point projections early and all day, keep NBA ownership live after lock for late swap, and grade your builds against a realistic field every time you re-run.
