MLB Prediction Market Promos: NLDS Game 3 Picks & Odds

MLB Tuesday brings us some decisive Game 3 in both National League Division Series, and our prediction market promos are right there with you. Across the five prediction market apps below, new users can unlock up to $2,250 in combined bonuses today.

The Dodgers and Braves are tied at a game apiece and shift to Atlanta, while the Brewers vs. Padres has a chance to end early in the two clubs' first-ever postseason meeting.

Both games air on national TV (FOX/FS1), and prediction markets are rolling out some of their biggest offers of the postseason – a mix of deposit bonuses that ask nothing more than funding an account and trade-triggered offers that unlock once you place a contract.

MLB Postseason Prices and Picks for Tuesday, Oct. 6

Prediction market contracts trade in cents, and every cent represents one percentage point of implied probability. Take the Dodgers' moneyline contract: at 50¢, the market is pricing Los Angeles at essentially a coin flip to win Game 3 outright.

Prices will keep moving between now and first pitch as traders react to lineup news and the inevitable late scratch – that's the market setting itself, not a signal to chase.

• Series state: Los Angeles took Game 1, 5-3, before Atlanta answered with a 3-2 win in Game 2 – the series is tied 1-1 as it shifts to Truist Park.
• Rotation depth: The Dodgers counter with four legitimate frontline arms in Yoshinobu Yamamoto, Tarik Skubal, Blake Snell, and Tyler Glasnow.
• Bigger picture: Atlanta actually won the regular-season series between these two clubs, 3-1, so the Braves aren't short on recent success against this lineup.

San Diego hosts Milwaukee in a series the two franchises have never played in October before, and tonight is an elimination game for the Padres. Take the Padres' moneyline price as the worked example: at 56¢, the market gives San Diego a modest but clear edge to survive and force a Game 4.

• Series state: Milwaukee won both games at home to open the series 2-0, so the Brewers can close it out tonight while the Padres are fighting to stay alive.
• Head-to-head history: The regular-season series was split by location – Milwaukee took two of three at American Family Field, but San Diego swept the return set at Petco Park, exactly where tonight's game is being played.
• Bigger picture: Milwaukee led MLB in team OBP and ranked second in runs scored this season, so this isn't a case of one offense being clearly better – it's about who's on the mound and who's desperate.

NDLS Pick 1: Los Angeles Dodgers Moneyline (50¢)

With Pérez unavailable for the series, Atlanta's rotation options behind Sale get thin fast, and a short series is exactly where a top-heavy staff like the Dodgers' gets to lean on its biggest advantage. Yamamoto, Skubal, Snell and Glasnow give Dave Roberts four legitimate frontline arms to mix and match – something Atlanta simply can't match turn for turn with a game-by-game series on the line.

None of this is a lock. Atlanta won the regular-season series and just showed in Game 2 it can win a bullpen-heavy, low-scoring game against this exact roster. But on balance, the pitching-depth gap tilts Game 3 toward Los Angeles.

Odds and lines are subject to change. Prediction market contract prices reflect implied probability, not a guarantee of outcome. Bet responsibly.

NDLS Pick 2: San Diego Padres Moneyline (56¢)

San Diego swept Milwaukee at Petco Park during the regular season, and Game 3 puts the Brewers right back into that same ballpark without their best starting pitcher. Facing elimination tends to sharpen a lineup, and the Padres have both the home history and the matchup edge to make Milwaukee work for the clincher.

This isn't a pick against Milwaukee's talent – the Brewers were one of the best teams in baseball all season and have won both games so far. It's a pick that ballpark history plus a thinned-out Milwaukee pitching plan gives San Diego the better path to forcing a Game 4.

What Are the Best MLB Prediction Market Promos?

Every platform featured on this page holds CFTC Designated Contract Market status. That distinction matters: you aren't placing a sportsbook bet with these apps; you're buying an event contract whose price reflects what traders collectively think will happen.

That structure has a few real consequences for how you should approach it:

• You're trading against other users, not the house. Because prices are set by the market rather than a sportsbook's odds team, there's no built-in "juice" working against you the way there is with traditional point-spread vig.
• Pricing can move fast and stay honest. With two-sided markets, a price that looks out of line gets corrected quickly by traders on the other side of the contract, rather than sitting mispriced on a book's board.
• The market menu keeps expanding. What started with game lines on football and basketball now covers player props, series outcomes and full-season futures across nearly every major sport, MLB included.

With the NLDS winding down and the ALDS, NLCS and ALCS all still ahead, every offer below stays relevant well past tonight's two games. Here's a closer look at each platform.

1. Polymarket Prediction Market Promo

Polymarket promo codeACTION keeps things simple – there's no trading requirement attached to this bonus, so the $25 lands as soon as your deposit clears. For a reader who's never traded an event contract before, that no-strings structure makes tonight's prices a low-pressure way to get comfortable with the app.

With multiple rounds left in October, a credit that clears on sign-up gives you a head start heading into the League Championship Series without needing to time your first trade perfectly.

2. Kalshi Prediction Market Promo

Kalshi promo code ACTION2000 unlocks the longest-tenured CFTC exchange in the group, and it shows in the depth of its market menu – beyond tonight's game lines, some props and futures markets extend well past the NLDS.

The $25 qualifying trade is a low bar relative to the potential payout, though the randomized bonus size means you should read the fine print before assuming you'll land at the top end. For a reader who wants to follow the entire bracket, Kalshi's broader menu makes it the pick for staying engaged through the ALCS and NLCS.

3. Novig Prediction Market Promo

Novig promo code ACTION unlocks a platform with an entire model built around letting traders post their own price rather than simply accepting whatever the board shows, which tends to produce sharper, tighter pricing than you'll find elsewhere.

Combined with uncapped trade volume and a tiered rewards structure, it's built for a reader who wants more control over the price they're getting on tonight's lines. Like Polymarket, this bonus clears on deposit with no trading requirement attached, so it's an easy one to claim before first pitch.

4. ProphetX Prediction Market Promo

ProphetX promo code TANBONUS keeps its menu sports-only, which means no digging through unrelated markets to find tonight's MLB lines. It also carries the largest qualifying volume and the largest payback of the group, which rewards a reader who's ready to commit a bit more upfront.

Instant cash-out is the other selling point – if your position on either Game 3 moves in your favor early, you aren't stuck waiting for the final out to lock in value.

5. FanDuel Predicts Prediction Market Promo

FanDuel Predicts promo needs no code – just sign up through the link – and it runs on a sportsbook-style interface, which should feel familiar if you've used FanDuel's betting app before, but it's backed by CME Group, giving it a different regulatory footing than a traditional book.

The five-day structure rewards sticking around rather than making one big trade – a good match for a multi-round postseason, since you can spread $1 trades across Game 3, Game 4, and into the next round at your own pace.

Is There More MLB Action for My Prediction Market Promos?

Every bonus unlocked off tonight's two games stays live well beyond this single night of baseball – there's a full bracket of postseason baseball left to use it on.

Here's how the rest of the week actually shakes out. Because the Dodgers-Braves series is tied 1-1, Wednesday's Game 4 in Atlanta is locked in no matter who wins tonight. The Brewers-Padres series is a different story: Milwaukee's 2-0 lead means a Game 4 only happens if San Diego forces it tonight. The ALDS, meanwhile, has both its Game 3s on Wednesday, with the Rays hosting the Yankees and the Guardians hosting the White Sox.

Game times and TV assignments are subject to change as the postseason schedule is finalized.
