Wednesday brings four Division Series elimination games, and our MLB prediction market promos give new users up to $2,275 in combined bonuses to trade today's postseason slate.
The White Sox and Rays both enter Game 3 with 2-0 ALDS leads, while the Dodgers and Brewers each hold 2-1 advantages in the NLDS. That leaves Cleveland, New York, Atlanta and San Diego facing elimination today.
All four games air nationally across TBS and FS1, starting with Guardians vs. White Sox at 4 p.m. ET and ending with Brewers vs. Padres at 10 p.m. ET. Between deposit bonuses and trade-triggered rewards, the five prediction market apps below give new users several ways to trade today's MLB postseason board.

MLB Postseason Prices and Picks for Wednesday, Oct. 7
Prediction market contracts trade in cents, with every cent representing roughly one percentage point of market-implied probability. A contract trading at 60¢, for example, implies about a 60% chance of the outcome happening and settles at $1 if it wins.
Prices can keep moving before first pitch as traders react to lineups, pitching news and late scratches. Check the live market before opening a position rather than treating an earlier price as fixed.
Wednesday's full MLB odds board gives us four games to trade.
| Matchup | Series | Time | Pick |
|---|---|---|---|
| Guardians at White Sox, Game 3 | CWS leads 2-0 | 4 p.m. ET | White Sox to win |
| Dodgers at Braves, Game 4 | LAD leads 2-1 | 6 p.m. ET | Dodgers to win |
| Rays at Yankees, Game 3 | TB leads 2-0 | 8 p.m. ET | Yankees to win |
| Brewers at Padres, Game 4 | MIL leads 2-1 | 10 p.m. ET | Padres to win |
ALDS Pick 1: Chicago White Sox to Win
Chicago gets the first chance Wednesday to punch its ticket to the ALCS after taking the opening two games against Cleveland.
The White Sox shut out the Guardians 3-0 in Game 1 before winning Game 2 by a 4-3 score. Cleveland now needs a road victory just to keep its season alive.
The biggest issue for the Guardians has been generating enough offense. Cleveland has scored only three runs through two games, which puts even more pressure on the pitching staff in an elimination game.
Chicago has been the stronger side through the first two games and now gets the opportunity to close the series at home.
Pick: Chicago White Sox to win
NLDS Pick 1: Los Angeles Dodgers to Win
Los Angeles enters Game 4 with a 2-1 series lead after taking control again Tuesday in Atlanta.
The Dodgers' biggest advantage throughout this series has been pitching depth. A postseason rotation with multiple frontline options gives Los Angeles several ways to manage a short series, especially once the bullpen becomes part of the equation.
Atlanta already showed it can win a low-scoring game against this roster, so this is not a spot to treat the Dodgers as automatic. The overall pitching setup still favors Los Angeles in a potential clincher.
Pick: Los Angeles Dodgers to win
ALDS Pick 2: New York Yankees to Win
New York is staring at elimination after Tampa Bay won the first two games of the ALDS.
The Yankees turn to Max Fried in Game 3, giving them their strongest starting-pitching setup of the series with their season on the line. Tampa Bay deserves credit for building the 2-0 advantage, but Yankee Stadium and Fried give New York a realistic path to extending the series.
The offense has to do more than it did through the opening two games. This is still the spot to back the Yankees to survive rather than paying a stronger price on Tampa Bay completing the sweep.
Pick: New York Yankees to win
NLDS Pick 2: San Diego Padres to Win
San Diego kept its season alive Tuesday and now gets another chance to extend the series at Petco Park.
Milwaukee remains one win away from the NLCS, but the Padres have already shown they can play their best baseball at home against this opponent. San Diego swept Milwaukee at Petco Park during the regular season and now enters Game 4 with some momentum after avoiding elimination.
The Brewers have been the better team across the full series. Home field and the matchup give San Diego enough of an edge to back the Padres to force a deciding Game 5.
Pick: San Diego Padres to win

What Are the Best MLB Prediction Market Promos?
The best MLB prediction market promos take several different forms during the postseason. Some rewards trigger from a deposit, while others require a minimum amount of trading activity before the bonus becomes available.
Prediction markets also work differently from traditional sports betting. Rather than placing a sportsbook wager against the house, users buy and sell event contracts whose prices change as traders take positions on each side.
That has a few practical consequences:
- You're trading with other users. Contract prices are driven by market activity rather than a traditional sportsbook odds board.
- Prices can move quickly. Lineup announcements, pitching changes and game results can all change what traders are willing to pay.
- The market menu extends beyond today's games. MLB contracts can include individual games, series outcomes, props and postseason futures.
With four Division Series elimination games today and the League Championship Series still ahead, every offer below can remain useful beyond Wednesday.
1. Polymarket Prediction Market Promo
The Polymarket promo code ACTION gives new users a $25 trading bonus after a qualifying $10 deposit.
That makes Polymarket one of the simpler offers on the board for a user who wants to get started before today's elimination games. The deposit requirement stays low, and there are still multiple postseason rounds available after the Division Series.

2. Kalshi Prediction Market Promo
The Kalshi promo code ACTION2000 carries the highest possible reward among today's offers.
Eligible new users complete $25 in qualifying trades to unlock one of the promotion's randomized bonus amounts. The reward can reach as high as $2,000, but that figure is the maximum rather than a guaranteed payout.
For users planning to trade throughout October, Kalshi also offers a deep menu that extends beyond today's game contracts into other postseason markets.

3. Novig Prediction Market Promo
The Novig promo code ACTION gives eligible new users $50 in Trade Credits after a qualifying $10 deposit.
Novig's order-book model lets traders either accept an available price or post their own and wait for another user to take the other side. That gives users more control over where they enter a market than simply accepting the first number available.
The $50 reward comes as Trade Credits, so read the promotional terms before deciding how to split them across today's games.

4. ProphetX Prediction Market Promo
The ProphetX promo code TANBONUS requires more trading volume than the deposit-driven offers, but it also provides one of the larger fixed rewards.
New users who complete $50 in qualifying trades can receive a $75 bonus. ProphetX keeps its menu focused on sports, which makes it easy to move from today's ALDS and NLDS games into the rest of the postseason.

5. FanDuel Predicts Prediction Market Promo
FanDuel Predicts does not require a traditional FanDuel Predicts promo code. New users should register through the promotional Click Here link instead.
The offer pays up to $100 in bonuses when eligible users make at least a $1 trade on five consecutive days. That structure fits postseason baseball because the qualifying activity can be spread across several games and rounds instead of one large position.
