Wembanyama and Gilgeous-Alexander 4 Leg Rematch Parlay Thunder at Spurs, leg by leg

The four legs

Shai Gilgeous-Alexander 25+ points

Who: Oklahoma City's engine, 33.2 minutes a game across 68 games last season.

The number: 31.1 points a game in 2025-26 and 27.6 across 15 playoff games. 25+ trades at 75 to 76 cents, a 75.5% chance, and it is the most traded line on this game, more than 2,100 contracts.

The matchup: Oklahoma City starts without Lu Dort, Isaiah Joe and Aaron Wiggins, so even more of the offense runs through him.

What beats it: San Antonio's length. Wembanyama behind the point of attack turns drives into kick outs, and a 22 point night beats this leg.

Victor Wembanyama 20+ points

Who: San Antonio's center and the middle of everything it does, 29.2 minutes a game across 64 games.

The number: 25.0 points a game last season and 23.8 across 22 playoff games, with 22 in Game 7 against this Thunder team. 20+ is the lowest points line Kalshi lists for him, at 78 to 79 cents, a 78.5% chance.

The matchup: Chet Holmgren draws him, and Holmgren's own Kalshi lines sit under 75% tonight. San Antonio's half court still runs through Wembanyama.

What beats it: A night spent on the perimeter chasing Holmgren, or foul trouble that shortens minutes already near 29 a game.

Victor Wembanyama 8+ rebounds

Who: The same Wembanyama, on his second and safest line.

The number: 11.5 rebounds a game last season and 10.9 in the playoffs. 8+ trades at 84 to 86 cents, an 85% chance, 30% under his average.

The matchup: Isaiah Hartenstein pulls in 9.4 a game for Oklahoma City, so the glass is contested, and 8 leaves room for that.

What beats it: Holmgren pulling him away from the rim for long stretches, which costs rebounds before it costs points.

Stephon Castle 10+ points

Who: San Antonio's other ball handler, 30.0 minutes a game across 68 games, with 7.4 assists a game.

The number: 16.7 points a game last season. 10+ trades at 86 to 89 cents, an 87.5% chance, the highest on the ticket and 40% under his average.

The matchup: With Tobias Harris questionable with a calf strain, San Antonio's shots go to the guards and Wembanyama.

What beats it: A passing night. When Castle runs the offense he can finish with 10 assists and 8 points.

Kalshi bid and ask read 2026-10-20 2:36 AM PT. The number beside each leg is Agent Dime’s own estimate, not a market price.

The price

Multiply the four asks and the ticket costs 46.0¢ for every dollar it pays: 2.18x, so $100 pays $217.61. The market’s own chances, the middle of each bid and ask, multiply to 44.1%. Agent Dime has all four landing at 44.1%.

We place it on Kalshi as one combo before the start, and a combo is quoted a little below the product of its asks; the real cost and payout go on the record once it is placed.

How it was built

• Dime 1.0 rules, all of them. Player props only: points, rebounds, assists and made threes. Every leg is 75% or better at the market, the middle of the bid and the ask. At most two legs on one player, and the ticket pays at least 2x at the asks.
• Two legs on Wembanyama. His points at the lowest line Kalshi lists, and his rebounds 30% under his average.
• The tightest prices on the slate. Gilgeous-Alexander and both Wembanyama lines show a one or two cent spread, so the ask is close to the middle and the ticket gives up little to the spread.
• Left off on purpose. Jalen Williams, who played 33 regular-season games last season and missed Game 7 with a hamstring injury. Chet Holmgren, whose lines sit under 75% tonight.

Where it can break

All four legs have to land. The market's own chances multiply to 44.1%, under the 46.0% the asks need. Tight spreads keep that gap small, but it is still a gap.

Gilgeous-Alexander's 25+ is the thinnest leg at 75.5%. It is 20% under his average, a smaller cushion than the other three.

Neither team had posted an official injury report when the ticket was priced. I re-check both before tip.
