Most restricted free agency dramas end the same quiet way, and the Jalen Duren board on Kalshi is priced like it knows that. One contract, Detroit, sits up near a dollar; the other thirty are pinned to the low single digits. Duren spent the whole summer in a public standoff with the Pistons over a new deal, but the mechanics of restricted free agency almost never let a player like him walk. His team can match any offer sheet, has said it will not do a sign-and-trade, and even his fallback option keeps him in Detroit. So the interesting question is not where he lands. It is whether a market that looks this settled is pricing the small chance that it is wrong, and whether a set of AI models that never saw the price would read the same board the same way. We ran it. They did, and landed a hair more confident than the crowd, with the one exception being a team the market has quietly left for dead.

The Quick Answer
As of August 20, 2026, Kalshi prices the Detroit contract at about 87 cents, with live quotes at 84 bid and 90 ask and a last trade at 90, while every other outcome on Jalen Duren's next-team board trades between 1 and 6 cents. Our price-blind AI panel scored the full board, all 30 teams plus a separate Retires / No Team contract, 31 outcomes in all, without seeing a single price, and blended the stays-in-Detroit outcome to about 89%, a hair above the crowd. The one real disagreement is small and specific: the models make the Sacramento Kings, the one team Duren actually met with about a sign-and-trade, the leader of the field at about 2.8%, against a market that has faded the Kings all the way to a penny.
- Market Favorite: Detroit, ~87¢ (a raw price; the full board carries a heavy overround, covered below)
- Model Favorite: the same, ~89% blend, one of the tightest crowd-vs-panel agreements this lane has produced
- Where The Models Split From The Price: they lift Sacramento to ~2.8% against a 1-cent line, while treating the crowd's higher prints on Brooklyn and Orlando as stale
- The Key Wrinkle Most Readers Miss: because Duren is a restricted free agent, Detroit can match any offer sheet, and even his one-year qualifying offer keeps him a Piston; only a completed sign-and-trade before October 21, 2026 flips this off Detroit
- The Panel's Logic In One Line: every realistic exit route runs through Detroit's veto, and Detroit has said no all summer, so this is a stays-put outcome first and a trade board second.
The restricted-free-agency mechanics that anchor the board, the narrow window that is closing, the full 31-outcome table, the Sacramento edge, the dark horses, and a plain-English guide to reading these prices are all below.

The Restricted-Free-Agency Mechanics That Anchor The Board
Start with the fact that shapes everything else: Duren is a restricted free agent, not an unrestricted one. He finished the four-year, roughly $19.4 million rookie-scale contract he signed as a 2022 first-round pick, and the Pistons tendered him a qualifying offer worth about $9.6 million this summer. That single word, restricted, is why this board looks nothing like a normal free-agency scramble. Any rival that wants Duren cannot simply outbid the field for his signature. It can sign him to an offer sheet, but Detroit has the right to match it, and the team has said flatly it intends to.
Duren has real leverage to push a big number, because he earned it. He had a breakout 2025-26, averaging about 19.5 points and 10.5 rebounds on 65.0% shooting across 70 games and making Third-Team All-NBA for the first time, which lifted the maximum he is eligible to sign for. But leverage over price is not the same as leverage over place. A 22-year-old All-NBA center is exactly the kind of asset a rebuilding front office keeps and pays, not one it lets leave for nothing, and Detroit has treated him that way all offseason.
The Pistons have said as much, repeatedly. Reporting through the summer has them declining a sign-and-trade; Brian Windhorst said in August that "I don't think a sign-and-trade is really on the table for Jalen Duren", and the team's stated plan is to match any offer sheet and bring him back. Even the nuclear option cuts Detroit's way: NBA insider Marc Stein reported Duren is weighing whether to sign the one-year qualifying offer if talks keep stalling, which would still leave him a Piston for 2026-27 before reaching unrestricted free agency next summer.
The Window Almost No One Prices Correctly
Here is the wrinkle that separates this board from a normal trade rumor. The market resolves to whichever team Duren is officially on before October 21, 2026, the eve of the season opener. If he is still a Piston on that date, by a new deal, a matched offer sheet, or the qualifying offer, the Detroit contract pays. A move after that date does not resolve any of these contracts YES.
That collapses the real off-Detroit window to a sliver. For any team other than Detroit to cash, a rival has to sign Duren to an offer sheet the Pistons then decline to match, or Detroit has to reverse itself and agree to the sign-and-trade it has publicly refused, and all of it has to finalize in the next few weeks. NBA training camps open at the end of September. The panel treated that shrinking calendar, stacked on top of Detroit's matching rights, as its single biggest driver, and it is the reason the models are, if anything, more confident in the stays-put outcome than a naive read of the board.
What A Cent Means Here
On Kalshi, a price in cents is roughly a probability in percent: an 87-cent contract implies the market thinks that outcome is about 87% likely, minus the exchange's spread and overround. The board below carries a large overround, so the raw cents add up to well more than 100; the section on reading these prices works the de-vig math in full. For now, read the cents as direction and rough size, not exact odds.
The Full Board: Kalshi Price Vs. Five Models
Here is the short version first, then every model's raw number.
The Board
| Outcome | Why it sits here | Market | Model blend |
|---|---|---|---|
| Detroit | Restricted free agent; team holds matching rights, rejects a sign-and-trade, and the qualifying-offer path also keeps him | ~87¢ | 89.2% |
| Sacramento | The one team Duren actually met with about a sign-and-trade; heavy volume, now faded to a penny | ~1¢ | 2.8% |
| Brooklyn | Cleared cap room to chase a max target; the crowd's higher field print | 4¢ | 1.5% |
| Boston | Draft capital to spend, but no concrete reported pursuit | 2¢ | 1.4% |
| LA Lakers | Pursued a center early, then pivoted to sign Walker Kessler | ~1¢ | 0.7% |
| Rest Of Field (26 Outcomes) | Penny-floor names with little or no reported story, plus the Retires / No Team contract | ~40¢ Combined | ~4.4% |

These are model estimates, not predictions of fact and not financial advice. The Blend column is the mean of each model's full-precision estimate; the per-model figures shown are rounded, so a displayed row can average a tenth of a point off the blend. The last column is a quick directional gap, the blend percentage minus the raw market price in cents; read it as direction and size, not a precise edge, because the raw board carries a large overround. Five of the panel's eight seats scored this board.

Sacramento: The One Team The Panel Lifts Off The Floor
Every model made the Kings the leader of the field, at right around 2.5 to 3.5%, against a market that prices them at a penny. That is not a random pick. Sacramento is the one team Duren actually met with in pursuit of a sign-and-trade at the start of free agency, and the Kings contract is the second most-traded outcome on the whole board, with heavy volume behind it. To the panel, a team that has already sat down with the player is categorically different from the two dozen teams that have said nothing.
Sacramento is the only suitor Duren is reported to have actually met with about a sign-and-trade, so even with Detroit blocking the path, the Kings deserve clear separation from a penny-floor field. — Claude Sonnet
The number is still small, because the same facts that keep the whole board tilted toward Detroit apply here too: the Pistons hold matching rights, they have refused the sign-and-trade, and the window is nearly shut. But the models' point is that the Kings are a live longshot, not a dead one, and the market's 1-cent line does not distinguish Sacramento from teams that have never been mentioned. It is the board's clearest example of a real story the crowd has flattened into the floor, and the fact that the Kings contract carries some of the board's heaviest volume makes that penny price all the more striking.
Brooklyn And Orlando: The Crowd's Stalest Lines
The two places the panel sits below the market are Brooklyn and Orlando. The Nets show a 4-cent last trade while the models blend them to about 1.5%. There is a real thread there, Brooklyn cleared cap space to chase a max free agent this summer, but a team with cap room is not the same as a team with a path, because Detroit can simply match any offer sheet the Nets write. Orlando is starker: it shows a 6-cent last trade on almost no volume, one of the thinnest books on the board, with no reported pursuit of Duren at all. That is a stale leftover print, not a signal. When a next-team contract shows a mid-single-digit price with only a handful of contracts behind it, the last trade is usually well above where anyone is actually willing to deal.
Where The Panel Changed Its Mind
Every model read the other four's anonymized reasoning and then revised. The revision round is where this board tightened from a loose agreement into a firm one. In the first pass the seats ranged from about 81% to 92% on the stays-put outcome, an 11-point spread; after the exchange they landed between 88% and 91%, a 3-point spread. Two arcs did the work.
Detroit holds matching rights, publicly rejects sign-and-trades, and the qualifying-offer fallback makes staying nearly certain, so almost every realistic path keeps him a Piston. — DeepSeek (revised its stays-put estimate up from 81% to 90% after the others stressed how completely restricted free agency routes every exit through Detroit)
As a restricted free agent, every exit route runs through Detroit's veto, and they publicly reject sign-and-trades and will match. — Claude Opus (came the other way, trimming from 92% to 88% to leave the reported suitors a little more of the field)
The seat that barely moved was Claude Fable, which held near 88 to 89% both rounds and kept Sacramento as its field leader throughout, calling the stays-put outcome the near-inevitable product of "restricted free agency plus Detroit's stated refusal to sign-and-trade and readiness to match." When the lowest seat jumps nine points toward the middle, the highest trims down to meet it, and a third never leaves, the agreement is doing real work rather than following the loudest voice.
What Would Change The Panel's Mind
This board is settled only as long as its inputs hold. Four concrete developments would move the number, each in a knowable direction:
- A Completed Sign-And-Trade Before October 21. The obvious one. Any finalized deal instantly resolves the board and moves the relevant team to 100 while Detroit goes to zero. Watch Sacramento first, since the Kings are the only team reported to have actually met with Duren about one.
- Detroit Reversing Its No-Sign-And-Trade Stance. The whole stays-put case rests on the Pistons refusing to cooperate. If the standoff turns bitter enough that Detroit decides to recoup value rather than match, the suitors the models price near zero come alive fast.
- A Signed Long-Term Deal Or A Matched Offer Sheet In Detroit. Either one pushes the stays-put outcome from the high 80s toward the mid-90s and drains what little life the field has left. This is the most likely resolution, and it still resolves Detroit YES.
- Duren Signing The Qualifying Offer. A quieter trigger that points the same way: taking the one-year, $9.6 million deal keeps him in Detroit for 2026-27 and settles this board on Detroit, while setting up a bigger fight next summer.
Dark Horses The Panel Won't Dismiss
Below Sacramento, a few names carry a small but real number for a specific reason rather than name recognition:
- Brooklyn blends to about 1.5%. The Nets have the cap space to write a real offer sheet, which is more than most of the field can say; the models keep them alive as the one team with the financial mechanism to at least force Detroit's hand, even if the Pistons are expected to match.
- Boston blends to about 1.4%. The Celtics have the draft capital to construct a package, but no concrete reported pursuit of Duren specifically, so the panel prices them as a name to watch rather than a live suitor.
- The LA Lakers blend to about 0.7%. They were an early name in the center market before they pivoted to sign Walker Kessler, which is why the models fade them below even the crowd's penny line.
None of these is a confident call. They are the panel's way of saying a board this lopsided still has a handful of live longshots, and the crowd has crushed most of them to a single indistinguishable penny.
The Traps: Rows That Look Like Signal But Are Not
Transparency matters more than a clean story, so here is where the table would mislead you:
- An 87-Cent Favorite Is Not A Settled Fact. It is the market's read that a move is unlikely in a narrow window, not a report that his contract is done. Camps have not opened, and the standoff is real.
- A 6-Cent Orlando Print Is Not A 6% Chance. It sits on one of the thinnest books on the board with no reported story behind it; read the depth, not the last trade, on a stale line.
- A Penny Price Is Not The Same As Zero. Sacramento in particular trades near the floor on a live, already-reported scenario; that is exactly where the panel thinks a sliver of value hides.
- The Board Does Not Sum To 100 Cents. The raw prices add to about 138 cents, so the market carries a real overround; do not read the raw cents as clean probabilities without adjusting for it.
How To Read These Prices
The models can tell you where they part from the crowd, but the number in front of you still has to be understood in context.
Work an example. The Detroit contract shows an 87-cent price. Taken at face value that is about an 87% chance. But on a 31-outcome board you get a fairer, spread-free read by normalizing every outcome so the field sums to 100. This board's raw prices add to about 138 cents, so dividing 87 by 138 gives a de-vigged figure closer to 63%. That lower number is the honest floor of the crowd's confidence once you strip the overround, and notably the panel's 89% blend sits above it, not below. The reason is that most of the overround here lives in the two dozen-plus contracts pinned at a single penny; those are the exchange's minimum tick on teams with no reported interest, not true 0.7% assessments, so a straight de-vig over-taxes the favorite. Always convert a raw cent price into its fair value before comparing anything; that habit is the whole idea behind turning Kalshi's cents into real odds.
A few honest points before reading too much into any number in the table above:
- Eligibility. Kalshi is a CFTC-regulated event-contract exchange, not a sportsbook. You must be 18 or older (18+) and located in an eligible state, and availability varies by state and can change.
- Liquidity And Spread. Only the Detroit contract carries a truly active, two-sided book; below it, most contracts sit near the penny floor on thin, one-sided marks, so getting in or out at your number is not always possible.
- A Moving Story. This is a live free-agency market that could resolve any day; Duren could re-sign, be dealt, or take the qualifying offer before October 21 and settle the board early, and these estimates reflect only what was known on August 20, 2026. Prices shown on this page refresh during any news wave.

The Bottom Line
The market and the models are looking at the same board and, for once, reading it the same way. Kalshi prices Jalen Duren to stay in Detroit near 87 cents; the panel blends the stays-put outcome to about 89%, a touch higher, and once you strip the board's overround the crowd's floor is even lower than either. This is the rare next-team market where the story is not a disagreement but a shared conclusion: a restricted free agent whose every exit route runs through a team that has said no all summer, with the calendar nearly out of room. The only crack of daylight is Sacramento, the one team Duren actually met with, which the panel lifts off the penny floor to the top of a thin field. If this method is your thing, the Jonathan Kuminga and Kawhi Leonard boards are the natural next reads, and every call here will be graded against what actually happens.
