MMA DFS Stacking Strategy: When To Stack UFC Fights On DraftKings + FanDuel
July 31, 2026
Most weeks, MMA DFS stacking is a mistake. On a full 12-fight UFC card, the standard advice holds: one fighter per fight, winners only, because two fighters splitting the same 15 minutes rarely both pay off their DraftKings or FanDuel salaries. But there is a specific situation where that default flips, and it shows up more often than you would think: the short slate. When cancellations and late dropouts shrink a card to nine or ten fights, the number of viable lineup combinations collapses, the field piles onto the same builds, and rostering both sides of the right fight becomes one of the cleanest ways to get different. The whole trick is knowing which fight qualifies, and by the end of this guide you will have a three-question test that answers that in about a minute per fight.
The Quick Answer
Stack a UFC fight only when the slate is short, roughly nine fights or fewer, and only when the fight itself is likely to go long, sits at a lighter weight class, and has takedowns and scrambles in its range of outcomes. Both fighters in a stack are paid out of the same minutes, so a quick knockout kills the stack: whichever side loses inside a round banks almost nothing. The three-question test, a worked example from a real short slate, and the stacks to avoid are all below.

Why Stacking Is Different In MMA
In baseball DFS you stack hitters because teammates score together: one swing can pay three roster spots at once. An MMA fight is the opposite. The two fighters you would stack are opponents, and they are splitting a fixed pool of minutes. Every significant strike one lands, the other absorbs. Under winners-take-most scoring, the loser of a fight is almost never part of an optimal lineup, so a stack is effectively a bet that a fight produces enough combined volume, takedowns, and scrambles that even the losing side keeps a useful floor.
That is a hard bet to win on a full card, which is why our UFC DFS strategy guide treats one-fighter-per-fight as the default. If you are still learning how DraftKings and FanDuel score a UFC card, start there; this guide assumes those fundamentals and builds the exception on top of them.
And the exception has a clear trigger.
The Short-Slate Trigger: Nine Fights Or Fewer
UFC cards shrink all the time. Injuries, weight-cut disasters, and illness protocols routinely turn a 12-fight card into a 10-fight card by Thursday and a 9-fight card by Saturday morning. The card our show broke down in January 2022, UFC Fight Night: Kattar vs. Chikadze, had been, in the hosts' words, hit from Maine to Spain: dropouts, protocol scratches, fights pushed to other events, and a card sitting at ten fights with one more bout in doubt of dropping it to nine.
Here is why the shrinking slate changes the math. With 12 fights you are filling DraftKings' six roster spots from 24 fighters, and lineup combinations are effectively endless. At 9 fights you are choosing from 18, everyone is reading the same three or four obvious values, and large chunks of the field converge on near-identical builds. On that January card, one 155-pound bout priced at $7,100 and $6,800 made roster construction so easy the show flatly called the fight "chalk city." When the field's lineups compress like that, duplication is your enemy, and stacking a fight is one of the few structural moves left that makes your lineup meaningfully different.
So the trigger is the slate. Which fight you stack is the actual skill, and that is the three-question test promised at the top.
The Three-Question Test For A Stackable Fight
Our show's read on stack selection boils down to three questions, asked in order. A fight needs all three answers to be yes.
1. Is this fight likely to go long? A stack needs minutes. Both fighters have to pay off their salary, which means the fight has to get past two and a half rounds at minimum, and ideally deep into the third. A fight with a live early knockout in its range is a fight where half your stack can be worth nothing 90 seconds in. This is where you deliberately pass on the fights you otherwise love for one-sided finish upside.
2. Is it at a lighter weight class? The show called the ideal version the "WEC stack": 155 pounds and under, a nod to the lighter-weight promotion that merged into the UFC. Lighter fighters bring pace, pressure, and volume, and they carry it for 15 minutes without the power to end things with one shot. Heavyweights are the mirror image, one-punch finishing ability and modest cardio, which is why heavyweight is the worst stacking division on any card.
3. Are there takedowns and scrambles in it? Strikes are a zero-sum fight for the same minutes, but grappling exchanges churn points on both sides: one fighter banks the takedown and control time, the other banks the reversal, the get-up, the submission attempt. A fight between two live grapplers who both get back to their feet is the rare spot where both fighters accumulate at once.
The test in one line: long, light, and grappling-rich. A stack needs minutes, pace, and two-way scoring, and a fight missing any one of the three is a one-fighter fight.
A Worked Example: A Short Slate Under The Test
Here is the test applied to that January 2022 short slate, using the actual DraftKings salaries from that week. FanDuel prices fights differently and its roster rules are its own, but the test grades the fight, not the salary cap, so the same yes/no verdicts carry straight into a FanDuel build:
| Fight (Weight Class) | DraftKings salaries | Stack verdict |
|---|---|---|
| Kattar Vs. Chikadze, Featherweight, 5 Rounds | $6,900 / $9,300 | Yes: five scheduled rounds, heavy striking volume, plus Kattar's underrated clinch-and-wrestling wrinkle; also the obvious stack the field sees |
| Royval Vs. Bontorin, Flyweight | $8,800 / $7,400 | Yes: flyweight pace, takedowns and submission attempts on both sides; the show leaned toward it stretching past 10 minutes |
| Collier Vs. Sherman, Heavyweight | $8,500 / $7,700 | No: heavyweight, live early finish (Sherman the puncher, Collier the decision grinder) |
| Chookagian Vs. Maia, Women's Flyweight | $8,900 / $7,300 | No: distance-likely but one-sided, with most of the volume projected to one fighter |
The row worth sitting with is the last one. The Chookagian fight passes the go-long test easily, every UFC win on her record to that point had come by decision, and it still fails as a stack, because a stack needs both sides producing. She landed 73 significant strikes in the first meeting with Maia; the fight projected as her volume against an opponent hunting occasional takedowns. That is a one-fighter fight that merely lasts a long time, and duration alone is not the bar.
Getting Different: Skip The Stack Everyone Else Sees
Now the leverage layer, and the reason the table above lists two yes verdicts instead of one. When a short slate pushes the field toward stacking at all, it defaults to the main event. It is the five-round fight, it is the one casual players watched the press conference for, and on this card it was a legitimate stack on the merits. Which is exactly the problem: a correct-but-obvious stack buys you very little separation.
The show's answer was the other yes row. Royval vs. Bontorin had everything the test asks for, flyweight pace like a pair of energizer bunnies, credible takedowns on both sides, scrambles and submission attempts likely, and almost none of the main event's attention. That is the callback to the WEC stack idea: the lighter the weight class, the better the stack, and the further from the main event, the better the leverage. When the field stacks fight one and you stack fight three with the same structural logic, you have the same upside with a fraction of the duplication.
Ownership is its own discipline, and our MMA DFS ownership and leverage breakdown goes deeper on when to eat chalk and when to fade it. For stacking purposes the rule is short: never pay leverage prices for the stack the whole field can see.
The Five-Round Value Piece
Short slates create one more structural edge, and it pairs naturally with a stack: the cheap side of the five-round main event. On the January 2022 card, Calvin Kattar was priced at $6,900 against Giga Chikadze at $9,300, a gap the show called disrespectful to a fighter who had gone five rounds with elite competition. A fighter at that price in a 25-minute fight has the most scheduled minutes on the slate to pay off the smallest salary, which is why the show made him a core cash-game piece and one of the best values on the board.
The risk side deserves honesty: Kattar was coming off a fight in which Max Holloway landed 447 total strikes on him over 25 minutes, throwing more than 700. A cheap five-round fighter is a value precisely because the market doubts him, and sometimes the market is right. But on a short card, the salary relief from a $6,900 five-rounder is what lets you fit an $8,800 stack piece elsewhere, and that interaction, cheap five-round value funding a leverage stack, is the short-slate build in one sentence.
The same fight-length and volume reads carry beyond salary-cap DFS. Significant-strike and takedown numbers on pick'em boards are priced fight by fight, and the projections behind Stokastic Prop Tools (PrizePicks + Underdog projections) run the same distance-and-pace analysis this guide applies to stacks.
Contest Selection When You Stack
A stack is a variance play, so put it where variance is paid. The show's contest hierarchy for MMA is a good default: entry-capped tournaments, 3-max and 20-max, are the sweet spot, because your opponents can only submit a handful of lineups apiece and a differentiated build goes further, with the hosts specifically liking 3-max for exactly that reason. Single-entry rewards a safer construction, a GPP (Guaranteed Prize Pool) with a massive field is where the main-event-stack duplication problem bites hardest, and the show's bankroll-builder pick between slates was DraftKings' multiplier-style contests. In cash games, skip stacking entirely and take the straightforward value, the $6,900 five-round fighter, not both sides of anything.
One more short-slate note from the show: when salaries make one fight chalk city, crossing that fight off entirely is itself a leverage play. Fewer fights means every shared roster spot hurts more, and the stack plus a deliberate fade is how a short-slate lineup stops looking like everyone else's.

Stacking Is A Tool, Not A Habit
Zoom back out. On a full card, the January 2022 show's hosts would tell you what every sharp MMA DFS player would: they are not big stackers, and neither should you be. Stacking earns its roster spots only when the slate shrinks and the field compresses, and even then only in fights that answer yes three times: long, light, and grappling-rich. The handicapping underneath is the same fight-reading you already do, and if you want to pressure-test a stack before you enter it, the Stokastic MMA Sims will show you how often both sides of your fight actually land in optimal lineups together.
