NBA action is in full swing across the country, and fans have ample opportunities to get in on the action themselves. Prediction markets are one of the best ways for people who want to make NBA picks without having to deal with house-skewed lines and sports betting odds.

Prediction exchanges, such as ProphetX, Kalshi, Polymarket and OG.com, have numerous markets available that allow users to make NBA picks on just about anything. Game winners (moneylines), spreads, game totals and player props are just a few options that users can make picks on across every prediction market platform. Participants can set their own market line, or choose an already-existing one, and be pitted head-to-head against opposing users who believe in a different outcome.

Now is the perfect time for sports fans to use prediction markets with the 2026-27 NBA season underway. Plus, new users can get started with the TSN promo code for a $40 prediction bonus on ProphetX.

The Sporting News has everything you need to know about how to trade NBA on prediction markets, including where to trade moneylines, spreads, totals, and props.

NBA moneyline prediction markets

Moneylines are one of the most common market types on prediction markets. Picking a moneyline essentially means choosing a specific team to win. Here are different types of moneyline markets that can be found on prediction platforms:

• San Antonio Spurs vs. LA Clippers: “Will the Spurs win the game?” trading at $0.78 (implying a 78% chance).
• LA Clippers vs. San Antonio Spurs: “Will the Clippers win?” trading at $0.28, meaning a $0.28 investment returns $1.00 if they pull off the upset.
• San Antonio Spurs: A futures moneyline contract on “Will the Spurs win the NBA Finals?” trading at $0.14.

NBA spread prediction markets

NBA spread prediction markets are peer-to-peer exchange platforms where users buy and sell contracts based on whether a team will cover a predetermined point spread. It revolves around the question “Will Team A win by more than X points, or will Team B lose by fewer than X points (or win outright)?”

Here are some examples of NBA spreads:

• Philadelphia 76ers (-3.5) vs. Boston Celtics: “Will the 76ers win by 4 or more points?” trading at $0.52 (implying a 52% chance they cover).
• Boston Celtics (+3.5) vs. Philadelphia 76ers: “Will the Celtics win, lose by 3 or fewer, or pull off the upset?” trading at $0.49, reflecting the opposing side of the same spread.
• Philadelphia 76ers (-7.5): A contract on the Sixers winning by 8+ points trading at $0.38 after a key injury report shakes up the prediction audience.

NBA totals over/under prediction markets

NBA totals (over/under) prediction markets feature users buying and selling contracts based on whether the combined final score of a game will be higher or lower than a predetermined number. Will the total combined points scored by both teams go Over or Under X?

This is what NBA totals can look like on prediction market platforms:

• Minnesota Timberwolves vs. Memphis Grizzlies (Over/under set at 220.5): “Will the total combined points be Over 220.5?” trading at $0.54 (implying a 54% chance).
• Minnesota Timberwolves vs. Memphis Grizzlies (Over/under set at 220.5): “Will the total combined points be Under 220.5?” trading at $0.47, representing the opposing outcome of the same line.

NBA player prop prediction markets

NBA player prop prediction markets are where participants trade shares based on individual player performance milestones. Essentially, users pick whether or not stats like a player tallying over 25 points today or whether or not a star will notch a triple-double.

Here are some more examples of player props on prediction markets:

• Points: Luka Doncic over 32.5 points trading at $0.55 (implying a 55% chance).
• Triple-double: Nikola Jokic to finish with a triple-double at $0.40, offering a higher payout for a harder-to-reach milestone.
• Rebounds + assists: Tyrese Maxey under 17.5 rebounds + assists trading at $0.48, representing the alternate side of a combo projection line.

ProphetX fees and commissions

ProphetX’s 2% commission is straightforward: a user only pays a fee if they walk away with a net profit on a market. If your trade loses, breaks even, or gets canceled, your fee is $0.

For example, if a user wagers $100 on a line that is marketed at 50% and wins, they’ll pay $2 on their profits. Therefore, their original $100 wager would be returned, along with $98 in profits. If that same $100 wager loses, they would only lose what they originally placed, with no commission.

Kalshi calculates fees per contract using the implied probability of the contract’s price (ranging from $0.01 to $0.99). Trades that are close to a 50-50 probability have the highest fees, while extreme favorites or underdogs have low fees attached to them.

If a user places a limit order (setting a custom price and waiting on the order book for someone else to match with them), you pay $0 in trading fees. Polymarket can reward these “makers” with daily cash rebates funded by taker fees. If a user clicks “Buy” or “Sell” to match instantly with an existing price, they pay a small taker fee depending on the market’s probability.
