Spurs priced as a coin flip to cover at home with the season on the line
The Spurs are 32-8 on the home floor per ESPN’s Game report. They’ve won both of their home games in this series, including a Game 4 overtime win that knotted the series 2-2.
The headline Game 6 spread-style contract has San Antonio winning by more than 3.5 points at 49¢ bid / 50¢ ask, with the No side at 50¢ bid / 51¢ ask. That’s an unusually tight market for a team facing elimination at home.
There is a split signal coming out of Game 5, with OKC’s 13-point road win pushing the series to 3-2. Shai Gilgeous-Alexander dropped 38 points, and the Thunder pulled away in the third quarter after the Spurs led by seven at the half, per NBC Sports’ Game 5 recap.
The totals market is leaning slightly toward the over. Over 218.5 combined points sits at 53¢ bid / 54¢ ask, with the Spurs’ team total over 112.5 at 47¢ bid / 48¢ ask and the Thunder’s over 107.5 at 54¢ bid / 55¢ ask.
Gilgeous-Alexander is averaging 31.1 points per game in the series against Victor Wembanyama’s 25.0, and Wembanyama is anchoring a Spurs defense that has held OKC under 110 in both home games.
Kalshi traders are pricing OKC as the slightly likelier team to clear its individual total despite playing on the road.
First half and second half markets
| Market | First half | Second half |
| Total points over | Over 104.5 at 56¢ bid / 58¢ ask | Over 108.5 at 60¢ bid / 63¢ ask |
| Higher total line over | Over 107.5 at 46¢ bid / 47¢ ask | Over 111.5 at 53¢ bid / 55¢ ask |
| OKC to win half by 1.5+ / 3.5+ | 1H 1.5+ at 35¢ bid / 39¢ ask | 2H 3.5+ at 32¢ bid / 33¢ ask |
| Spurs blowout | 1H by 23.5+ at 0¢ bid / 3¢ ask | 2H by 15.5+ at 6¢ bid / 9¢ ask |
Key factors for tonight’s matchup
The lineup variables most likely to move these numbers before tip-off are on the OKC side. Jalen Williams, the Thunder’s second option behind Gilgeous-Alexander, played through a hand injury in Game 5, and rookie guard Ajay Mitchell’s status was flagged as a game-time call.
The highest-volume and highest-open-interest markets are the full-game winner, the Spurs -3.5-style spread contract, and the main totals. The team-total and half-game markets are useful context, but they are much thinner than the core Game 6 boards.
Terms and conditions for tonight’s promo
The RATE promo code is open to new Kalshi accounts only, with traders required to be 18 or older and to complete identity verification at sign-up. The code must be entered during account creation.
The qualifying step is a $10 deposit. Once that deposit clears, Kalshi posts $10 in site credit to your account, which can be used on the Game 6 board, the series winner market, and Finals contracts.
The bonus is site credit rather than withdrawable cash, and any profit from contracts traded with the bonus settles to the account balance under Kalshi’s standard withdrawal terms.
The promo code RATE extends beyond Game 6 market settlement and can be use on any contract.
