Best Rebounds Prop Today – Isaiah Hartenstein 8+ Rebounds

Isaiah Hartenstein is the rebounding anchor next to Chet Holmgren in the Thunder's typical starting group, and he gets plenty of chances when Spurs shots come off the rim.

Victor Wembanyama will pull much of Oklahoma City's rim attention, which leaves boxing out as the Thunder's main job, and Hartenstein is the big who handles it. The board quotes 61%, but our $100 ticket filled at an average of 62.08¢, so that's the price we're using here.

A $100 buy at a 62.08¢ average price works out to roughly 161 shares, each worth $1 if the contract resolves Yes, and the gap between that raw share value and Polymarket's stated return reflects order book depth and fees, not an error.

• If Hartenstein grabs 8 or more rebounds: return of $156.94.
• If not: the full $100 stake is lost, since Polymarket contracts settle all-or-nothing.

It's the shortest price on our card, and the return is about 1.6x your stake.

Best Assists Prop Today – Shai Gilgeous-Alexander 6+ Assists

Shai Gilgeous-Alexander averaged 7.1 assists through the playoffs before last season's Western Conference finals, and he keeps creating for others when defenses load up on him.

Against this Spurs defense he handed out 12 assists in a game last postseason even while shooting 7-of-23, which shows how he can still reach this number on a bad scoring night.

At a 61¢ average price, a $100 buy is roughly 164 shares, each worth $1 on a Yes resolution.

• If Gilgeous-Alexander dishes 6 or more assists: return of $159.60.
• If not: the full $100 stake is lost, since Polymarket contracts settle all-or-nothing.

That's about 1.6x your stake on one of the steadier assist numbers on the board.

Best Rebounds Prop Today – Victor Wembanyama 12+ Rebounds

Victor Wembanyama had 24 rebounds in the Western Conference finals opener, a double-overtime Spurs win in Oklahoma City, so the ceiling on this number is clear.

The reigning Defensive Player of the Year is San Antonio's main rim protector and rebounder, and Holmgren and Hartenstein have to box him out perfectly for 12 to be out of reach. The board quotes 52%, and our $100 ticket filled at an average of 52.44¢.

A $100 buy at a 52.44¢ average price is roughly 191 shares, each worth $1 if the contract resolves Yes.

• If Wembanyama grabs 12 or more rebounds: return of $184.60.
• If not: the full $100 stake is lost, since Polymarket contracts settle all-or-nothing.

That's more than 1.8x your stake on a number the star center has already cleared against this exact opponent.

Best Points Prop Today – Shai Gilgeous-Alexander 30+ Points

Shai Gilgeous-Alexander is a two-time reigning MVP, and last season he reached 100 straight games with 20 or more points.

The Spurs pushed him into his worst offensive start of the postseason in last year's series, so 30 is no gimme against the reigning Defensive Player of the Year. A coin-flip price is still fair for a scorer of his caliber.

At a 51¢ average price, a $100 buy works out to roughly 196 shares, each worth $1 on a Yes resolution.

• If Gilgeous-Alexander scores 30 or more points: return of $189.62.
• If not: the full $100 stake is lost, since Polymarket contracts settle all-or-nothing.

That's nearly 1.9x your stake on the MVP's most important scoring number.

Best Blocks Prop Today – Victor Wembanyama 4+ Blocks

Victor Wembanyama is the reigning Defensive Player of the Year and one of the league's most disruptive rim protectors, which makes four blocks a natural rung on the ladder.

Oklahoma City attacks the rim with Gilgeous-Alexander's drives all night, and that gives Wembanyama plenty of chances to rise up at the basket. The board quotes 44%, and our ticket filled at an average of 44.33¢.

A $100 buy at a 44.33¢ average price is roughly 226 shares, each worth $1 if the contract resolves Yes.

• If Wembanyama blocks 4 or more shots: return of $217.20.
• If not: the full $100 stake is lost, since Polymarket contracts settle all-or-nothing.

That's more than 2.1x your stake on the most disruptive defender on the board.

Best Points Prop Today – Jalen Williams 20+ Points

Jalen Williams is back at full strength after missing 55 of the Thunder's first 90 games last season, including the playoffs.

While he was out, Ajay Mitchell averaged 21.2 points in his place, and Oklahoma City now has both scoring options available alongside Gilgeous-Alexander. The board quotes 42%, and our ticket filled at an average of 43¢.

At a 43¢ average price, a $100 buy is roughly 233 shares, each worth $1 on a Yes resolution.

• If Williams scores 20 or more points: return of $223.70.
• If not: the full $100 stake is lost, since Polymarket contracts settle all-or-nothing.

That's more than 2.2x your stake on a scorer who looks fully healthy.

Best Three-Pointers Prop Today – Devin Vassell 3+ Three-Pointers

Devin Vassell is San Antonio's go-to wing shooter, and the board sets his line at three makes.

He scored 23 points against Oklahoma City in the NBA Cup semifinal win, and the Spurs' spacing around Victor Wembanyama gives him clean looks off the kick-out. With Tobias Harris out with a calf strain, even more of the perimeter shot diet runs through San Antonio's young core.

A $100 buy at a 41¢ average price works out to roughly 244 shares, each worth $1 if the contract resolves Yes.

• If Vassell makes 3 or more three-pointers: return of $234.29.
• If not: the full $100 stake is lost, since Polymarket contracts settle all-or-nothing.

That's more than 2.3x your stake on San Antonio's go-to wing shooter.

Best Three-Pointers Prop Today – Stephon Castle 2+ Three-Pointers

Stephon Castle's 39% price is the lowest on the entire three-pointers board, which is exactly why the return is attractive.

He's a ball handler first, but the Spurs' spacing around Wembanyama and the extra perimeter possessions with Tobias Harris out give him open catch-and-shoot chances. The board quotes 39%, and our ticket filled at an average of 40¢.

At a 40¢ average price, a $100 buy is exactly 250 shares, each worth $1 on a Yes resolution.

• If Castle makes 2 or more three-pointers: return of $240.00.
• If not: the full $100 stake is lost, since Polymarket contracts settle all-or-nothing.

That's exactly 2.4x your stake on the lowest-priced number on the three-pointers board.

Best Assists Prop Today – Stephon Castle 8+ Assists

Stephon Castle's 6+ assists line is the top-priced assist number on the board at 64%, so 8+ is the next rung up the ladder.

He runs San Antonio's offense as the lead creator, and Wembanyama's rolls and kick-outs give him easy passing windows. If Oklahoma City sends help at Wembanyama, the assists can pile up fast.

This 8+ market wasn't on our board screenshot, so the price comes from the ticket: a 35% quote on screen with an average fill of 36.43¢.

A $100 buy at a 36.43¢ average price is roughly 275 shares, each worth $1 if the contract resolves Yes.

• If Castle dishes 8 or more assists: return of $262.93.
• If not: the full $100 stake is lost, since Polymarket contracts settle all-or-nothing.

That's more than 2.6x your stake on San Antonio's lead creator.

Best Three-Pointers Prop Today – Julian Champagnie 3+ Three-Pointers

Julian Champagnie is the Spurs' spot-up specialist, and he shares the board's top 2+ price with Wembanyama at 61%.

Moving to 3+ shrinks the probability but raises the return a lot, and he started the Western Conference finals opener in a San Antonio lineup built around shooting next to Wembanyama. The board quotes 34%, and our ticket filled at an average of 34.76¢.

At a 34.76¢ average price, a $100 buy works out to roughly 288 shares, each worth $1 on a Yes resolution.

• If Champagnie makes 3 or more three-pointers: return of $275.25.
• If not: the full $100 stake is lost, since Polymarket contracts settle all-or-nothing.

That's more than 2.7x your stake, the longest shot on our card.

Spurs vs Thunder Prediction: Moneyline, Spread and Total

Before the player prop boards, here is where the game lines stand on Polymarket.

Oklahoma City Thunder Moneyline

Oklahoma City is priced as a near pick'em on the road, sitting at 50% to win outright on the moneyline in a rematch of last season's conference finals.

San Antonio Spurs Moneyline

San Antonio is the slight home favorite at 51% to win outright, with Victor Wembanyama and the home crowd as the edge.

Spurs vs Thunder Spread

Oklahoma City to win by more than 1.5 points is priced at 48% Yes against 54% No, a spread that tells you how close the market sees this one.

Spurs vs Thunder Total

The total sits at 231.5 points, priced at 49% Yes on the Over against 52% No on the Under.

NBA Points Props: Wembanyama, Gilgeous-Alexander and More

Here is every player on Polymarket's points board, sorted from the safest number down to the longest shot.

• Ajay Mitchell (OKC) (Points 10+: Yes 67%): Mitchell averaged 21.2 points when he stepped into the starting five during Jalen Williams' playoff absence, so 10 is a low bar even in a reserve role.
• Stephon Castle (SAS) (Points 15+: Yes 59%): A heavy-usage guard whose drives keep 15 points well within range.
• Victor Wembanyama (SAS) (Points 25+: Yes 57%): He scored 41 points in last season's Western Conference finals opener, and the market treats 25 as a better-than-even number.
• Dylan Harper (SAS) (Points 15+: Yes 57%): Harper scored 24 points in a starting role against Oklahoma City last postseason, and his price is up 3 points on the board.
• De'Aaron Fox (SAS) (Points 15+: Yes 54%): Fox was averaging 18.8 points in last year's playoffs, which makes 15 a fair floor when he's on the floor.
• Jared McCain (OKC) (Points 10+: Yes 54%): A bench scorer's number that depends on how much run the Thunder guard rotation gives him.
• Cason Wallace (OKC) (Points 10+: Yes 52%): Wallace is better known for his defense, so 10 points is a near coin flip rather than a given.
• Shai Gilgeous-Alexander (OKC) (Points 30+: Yes 51%): The two-time reigning MVP sits at a coin flip for 30 against the reigning Defensive Player of the Year.
• Julian Champagnie (SAS) (Points 10+: Yes 46%): A spot-up shooter in San Antonio's young starting group, so his total mostly depends on whether the threes fall.
• Keldon Johnson (SAS) (Points 10+: Yes 43%): Johnson's scoring comes in bench minutes, which keeps this number below 50%.
• Jalen Williams (OKC) (Points 20+: Yes 42%): Williams is fully healthy again, but 20 is still a tall order against San Antonio's length.
• Chet Holmgren (OKC) (Points 15+: Yes 39%): Holmgren's pick-and-pop game can get him there, but the Spurs' length makes 15 a real challenge.
• Devin Vassell (SAS) (Points 15+: Yes 36%): Vassell scores in bursts, which explains why 15 sits at a lower price than most starters.
• Isaiah Hartenstein (OKC) (Points 10+: Yes 35%): Hartenstein's price dropped 7 points on the board, a sign the market sees him as a rebounder first and a scorer second.

NBA Rebounds Props

The rebounds board is led by Oklahoma City's Isaiah Hartenstein, with Victor Wembanyama's 12+ line sitting near a coin flip.

• Isaiah Hartenstein (OKC) (Rebounds 8+: Yes 61%): The highest price on the board, even after slipping 6 points.
• Shai Gilgeous-Alexander (OKC) (Rebounds 4+: Yes 59%): Four boards is a modest ask for a guard with his usage and size.
• Devin Vassell (SAS) (Rebounds 4+: Yes 59%): A starting wing playing heavy minutes should find four rebounds without much trouble.
• Chet Holmgren (OKC) (Rebounds 8+: Yes 56%): His price is down 5 points, but he'll see plenty of defensive boards when Wembanyama drifts to the perimeter.
• Dylan Harper (SAS) (Rebounds 5+: Yes 56%): Harper's price is up 4 points on the board, helped by his size at guard.
• Keldon Johnson (SAS) (Rebounds 4+: Yes 55%): A physical forward who should pick up four rebounds in bench minutes.
• Julian Champagnie (SAS) (Rebounds 5+: Yes 54%): A long forward in the starting group who gets rebounding chances from the wing.
• Victor Wembanyama (SAS) (Rebounds 12+: Yes 52%): He grabbed 24 rebounds in last season's series opener, so 12 is within reach.
• Cason Wallace (OKC) (Rebounds 4+: Yes 51%): Four rebounds is a coin flip for a guard whose price is down 2 points.
• Jalen Williams (OKC) (Rebounds 5+: Yes 49%): Five rebounds from the wing is a near coin flip.
• De'Aaron Fox (SAS) (Rebounds 4+: Yes 49%): Fox's guard role keeps this one right at even money.
• Stephon Castle (SAS) (Rebounds 6+: Yes 44%): The highest rebound line for any Spurs guard on this board.
• Jared McCain (OKC) (Rebounds 3+: Yes 44%): Three boards is a reach for a bench guard.
• Ajay Mitchell (OKC) (Rebounds 4+: Yes 41%): The lowest price on the board, down 4 points, reflecting his role as a scoring guard.

NBA Assists Props

Stephon Castle and Shai Gilgeous-Alexander lead the assists board, which is full of guards at 6+ and 3+ lines.

• Stephon Castle (SAS) (Assists 6+: Yes 64%): The highest-priced assist play on the board as San Antonio's lead ball handler.
• Shai Gilgeous-Alexander (OKC) (Assists 6+: Yes 60%): His price is down 4 points, but he averaged 7.1 assists through the playoffs before last season's conference finals.
• Dylan Harper (SAS) (Assists 4+: Yes 60%): Harper had six assists in the series opener against Oklahoma City.
• Ajay Mitchell (OKC) (Assists 3+: Yes 59%): His price is down 5 points, but three assists is a modest hurdle for a guard.
• Cason Wallace (OKC) (Assists 3+: Yes 52%): Wallace's price slid 6 points, leaving this one close to a coin flip.
• Isaiah Hartenstein (OKC) (Assists 3+: Yes 51%): A passing big who finds cutters out of the high post.
• Jalen Williams (OKC) (Assists 5+: Yes 49%): Williams' playmaking role keeps five assists in play, even with his price down 4 points.
• Devin Vassell (SAS) (Assists 3+: Yes 45%): A secondary creator whose price is down 5 points.
• De'Aaron Fox (SAS) (Assists 6+: Yes 44%): Fox averaged 5.8 assists in last year's playoffs, so 6 sits just above his norm.
• Victor Wembanyama (SAS) (Assists 4+: Yes 42%): He has the passing touch from the high post, but four assists is a lot for a center.
• Chet Holmgren (OKC) (Assists 2+: Yes 41%): A low line for a connective big, even after his price slid 4 points.
• Jared McCain (OKC) (Assists 2+: Yes 40%): Two assists is a small number, but his price is down 3 points.

NBA Three-Point Props

Polymarket's three-pointers board mixes 1+ lines for Oklahoma City's shooters with 2+ and 3+ lines for San Antonio's wings.

• Ajay Mitchell (OKC) (Three-Pointers 1+: Yes 68%): A single three is the lowest rung on the ladder, and Mitchell holds the board's top price.
• Jalen Williams (OKC) (Three-Pointers 1+: Yes 67%): One make from a scorer with Williams' range is a strong bet.
• Chet Holmgren (OKC) (Three-Pointers 1+: Yes 66%): His price fell 8 points, the sharpest drop on this board, but he's still a pick-and-pop threat.
• Keldon Johnson (SAS) (Three-Pointers 1+: Yes 63%): A bench wing who gets open looks when the Spurs spread the floor.
• Victor Wembanyama (SAS) (Three-Pointers 2+: Yes 61%): A stretch big who launches from deep, and the price is steady.
• Julian Champagnie (SAS) (Three-Pointers 2+: Yes 61%): San Antonio's spot-up specialist sits level with Wembanyama.
• Jared McCain (OKC) (Three-Pointers 2+: Yes 59%): A shooter by trade, though his price is down 6 points.
• Shai Gilgeous-Alexander (OKC) (Three-Pointers 2+: Yes 51%): The MVP is a coin flip for two threes.
• Cason Wallace (OKC) (Three-Pointers 2+: Yes 51%): A corner threat who shares the same price as Gilgeous-Alexander.
• De'Aaron Fox (SAS) (Three-Pointers 2+: Yes 47%): Fox is priced just under a coin flip for two makes.
• Dylan Harper (SAS) (Three-Pointers 2+: Yes 44%): Harper's price is up 4 points, one of the few risers on the board.
• Devin Vassell (SAS) (Three-Pointers 3+: Yes 41%): The top rung for San Antonio's wing shooter, and the line we back in our picks above.
• Stephon Castle (SAS) (Three-Pointers 2+: Yes 39%): The lowest price on the board, and the other line we back above.

NBA Steals Props

Steals are the thinnest board on the card, with Dylan Harper and Victor Wembanyama on top.

• Dylan Harper (SAS) (Steals 1+: Yes 68%): Harper swiped seven steals in the series opener against Oklahoma City last postseason.
• Victor Wembanyama (SAS) (Steals 1+: Yes 68%): Long arms in the passing lanes make one steal an easy ask.
• Stephon Castle (SAS) (Steals 1+: Yes 67%): A point-of-attack defender who gets his hands on the ball.
• Cason Wallace (OKC) (Steals 2+: Yes 59%): One of the Thunder's top perimeter defenders, though his price slid 7 points.
• Shai Gilgeous-Alexander (OKC) (Steals 2+: Yes 41%): Two steals is a stretch, and his price is down 6 points.
• De'Aaron Fox (SAS) (Steals 2+: Yes 39%): Fox's price is down 5 points for two steals.
• Jalen Williams (OKC) (Steals 2+: Yes 36%): The largest drop on the whole board, down 10 points.

NBA Blocks Props

Blocks are the shortest board, but Wembanyama's 4+ line is the one to watch.

• Isaiah Hartenstein (OKC) (Blocks 1+: Yes 58%): A single block is a modest ask for Oklahoma City's starting big, and his price is up 1 point.
• Shai Gilgeous-Alexander (OKC) (Blocks 1+: Yes 57%): A guard with a knack for chase-down blocks, even with his price down 5 points.
• Chet Holmgren (OKC) (Blocks 2+: Yes 53%): A premier shot-blocker whose price is down 2 points.
• Victor Wembanyama (SAS) (Blocks 4+: Yes 44%): The reigning Defensive Player of the Year is the only player on the board with a 4+ line.

NBA Points + Rebounds + Assists Props

Polymarket also prices combined points, rebounds and assists, and Wembanyama and Gilgeous-Alexander lead at 40+.

• Victor Wembanyama (SAS) (Points + Rebounds + Assists 40+: Yes 64%): The top-priced line on the board, and he had 41 points and 24 rebounds in one game of last season's conference finals.
• Shai Gilgeous-Alexander (OKC) (Points + Rebounds + Assists 40+: Yes 62%): Points, rebounds and assists all feed this number for the MVP.
• Isaiah Hartenstein (OKC) (Points + Rebounds + Assists 20+: Yes 56%): Rebounds and passing do most of the work here.
• Devin Vassell (SAS) (Points + Rebounds + Assists 20+: Yes 55%): A starting wing who contributes in all three categories.
• Ajay Mitchell (OKC) (Points + Rebounds + Assists 20+: Yes 53%): Mitchell averaged 21.2 points in the playoff stretch when he started.
• Stephon Castle (SAS) (Points + Rebounds + Assists 30+: Yes 52%): Assists and rebounds from the lead guard give him a strong floor.
• Jalen Williams (OKC) (Points + Rebounds + Assists 30+: Yes 52%): A fully healthy Williams can fill all three columns.
• Cason Wallace (OKC) (Points + Rebounds + Assists 20+: Yes 42%): Wallace's value comes more from defense than box score volume.
• Dylan Harper (SAS) (Points + Rebounds + Assists 30+: Yes 37%): A second-year guard whose points, rebounds and assists have room to grow.
• De'Aaron Fox (SAS) (Points + Rebounds + Assists 30+: Yes 33%): Fox needs a big scoring night to get close.
• Jared McCain (OKC) (Points + Rebounds + Assists 20+: Yes 30%): A bench guard with a limited box-score floor.
• Chet Holmgren (OKC) (Points + Rebounds + Assists 30+: Yes 28%): The lowest price on the board for a skilled big.

What's Moving the Market

Prediction markets prices move for several reasons, and the biggest swing on this board is the game itself, where Oklahoma City's moneyline price is up 5 points to 50% and San Antonio's is down 5 points to 51%.

Among the NBA props, the Thunder bigs saw the sharpest drops. Chet Holmgren's 1+ three-pointers price fell 8 points to 66%, and Isaiah Hartenstein's 10+ points price fell 7 points to 35%.

On the other side, Dylan Harper is one of the few risers, with his 15+ points price up 3 points, his 2+ three-pointers price up 4 and his 5+ rebounds price up 4. Jalen Williams' 20+ points price also ticked up 2 points to 42%.

Steals moved the most overall, with Williams' 2+ steals price down 10 points to 36% and Cason Wallace's 2+ steals price down 7 points to 59%. It's a reminder that these thinner props can reprice quickly, especially with Tobias Harris out for San Antonio and Otega Oweh out for Oklahoma City.
