TRADE WITH POLYMARKET'S $20 OFFER
Once you've claimed the Polymarket promo code
Right now, the biggest opportunities are centered around the second half of the MLB season, NFL futures ahead of the regular season, and prediction markets covering politics, technology, and other major news events.
⚾ MLB Second-Half Markets
The second half is where MLB futures actually start to move. Rosters aren't set yet (the August 3 trade deadline is days away), and one deal can move a division or Wild Card contract before the market catches up. A contender landing a front-line starter, or a seller shipping out its closer, reprices a market fast.
The clearest example right now is Tarik Skubal. Detroit's two-time Cy Young winner is the marquee name on the block ahead of Monday's deadline, and the reporting has tilted toward a deal getting done. Whichever contender lands him would see its World Series price move the moment it's official, and the market is already reacting to the speculation, so a contract you buy today could look very different once the deadline passes.
That's a good reason to put some of the $20 bonus into baseball now, as you're not stuck with one call. Buy a team's playoff or division contract today, and if a trade or a hot streak pushes the price your way, sell the position and take the difference instead of waiting on the final standings.
Polymarket keeps markets open on division winners, league pennants, and World Series futures the rest of the way.
| Market window | What it means for your trades |
|---|---|
| Now through the Aug. 3 deadline | Deadline deals can reprice division and Wild Card contracts quickly |
| The August stretch | Buyers and sellers pull apart, and prices move on every winning or losing streak |
| September playoff push | Wild Card contracts get the most volatile as teams clinch or drop out |

Top MLB Markets
⚾ World Series Winner: Back the team you think will win the Fall Classic.
🏆 Division Winners: Predict which clubs will finish atop each division.
📈 League Pennants: Trade on the American League and National League champions.
🔥 Playoff Race: Follow teams fighting for the final Wild Card spots as the regular season winds down.
💡 Pro Tips:
- Deadline acquisitions and injuries can quickly reshape championship odds.
- Division races often create value opportunities before the market fully adjusts.
- Futures markets become more volatile as teams clinch playoff berths or are eliminated.
The beauty of Polymarket is its flexibility. If your outlook changes after a major trade, injury, or winning streak, you can buy or sell your position before the market settles.

WHAT IS POLYMARKET?
The Polymarket app is a CFTC-regulated prediction market platform that lets you trade on the outcomes of real-world events.
Instead of placing traditional sportsbook wagers, you'll buy and sell contracts tied to specific outcomes across categories such as sports, politics, economics, technology, culture, and weather.
POLYMARKET PRICES AND IMPLIED PROBABILITY
One of the first things you'll notice on Polymarket is that contracts are priced between $0 and $1. The good news? Converting those prices into probabilities is incredibly easy.
On Polymarket, a contract's price equals its implied probability:
For example:
- A Yes share trading at $0.25 implies about a 25% chance.
- A Yes share trading at $0.60 implies about a 60% chance.
- A Yes share trading at $0.80 implies about a 80% chance.
This makes it easy to see how confident the market is in a particular outcome, whether it's an MLB game, election result, or major news event.
Another thing many traders like is that prices constantly move as new information becomes available. If a market moves in your favor, you don't always have to wait for the final outcome. You can often sell your position before the event is resolved and lock in a profit.
As you become more comfortable with the platform, you'll start comparing Polymarket prices with sportsbook odds and other prediction markets to spot potential value opportunities.
IS POLYMARKET LEGAL?
Yes. The Polymarket app is a CFTC-regulated event contract platform available to eligible users in much of the United States.
What makes you eligible:
- To access the Polymarket app, you must be physically located in an eligible state and complete identity verification. Like other regulated event contract platforms, Polymarket uses geolocation technology to confirm your location before allowing trading activity.
- You must be at least 18 years old to create an account, although age requirements may change by jurisdiction.
- The Polymarket app is not available in Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada, and Ohio.
Can you use Polymarket in California?
Yes. California residents can use the Polymarket app as long as they're physically located in the state, complete identity verification, and meet the platform's eligibility requirements.
Can I use Polymarket in Texas?
Yes. Polymarket is available in Texas. Users must complete identity verification and pass geolocation checks before they can trade.
Does Polymarket work in Florida?
Yes. Florida is one of the states where eligible users can access the Polymarket app. You'll need to verify your identity and be physically located in Florida when trading.
WHO IS POLYMARKET FOR?
Polymarket suits anyone who follows sports, politics, or news and wants to trade on outcomes. No trading experience required.
If you enjoy following a story and having a stake in how it ends, the platform gives you an interactive way to engage with events you're already paying attention to.
Polymarket tends to appeal most to:
- Sports Fans: Trade on everything from the MLB to championship futures and major sporting events.
- News Followers: React to breaking headlines, political developments, and major economic stories as they unfold.
- Data-Driven Users: If you enjoy looking at probabilities, trends, and market sentiment, Polymarket offers plenty to explore.
- Value Seekers: Prices update in real time, allowing users to buy and sell positions as events develop.
SPORTS ON POLYMARKET VS TRADITIONAL SPORTSBOOK
Polymarket is a peer-to-peer exchange: prices are set by traders, not a bookmaker, so there isn't built-in vig.
Every contract trades between $0 and $1, representing the crowd's estimated probability of an outcome. You post a price, another trader accepts it, and the contract fills.
Here is a quick breakdown of how the two stack up:
| Feature | Polymarket | Traditional Sportsbook |
| Odds Source | User-driven market (peer-to-peer) | Set by the house (Oddsmakers) |
| Primary Cost | Trading fees (Taker fee) + Network fees | The "Vig" or "Juice" |
| Trading On | Probability of an outcome (1¢ to 99¢) | Moneyline, Spread, Totals |
| Funding Method | U.S. dollars (ACH, debit card, Apple Pay) | Fiat (Debit Card, PayPal, Bank Transfer) |
| Regulation | CFTC-Regulated | State-by-state gaming commissions |
| Account | Standard verified user account | Centralized user account |
Another big difference with sportsbooks, is that Polymarket is legal in states where betting is not allowed, like California, Texas and Florida.

HOW SPORTS MARKETS ACTUALLY WORK
Polymarket allows users to trade on the probability of an outcome happening. That could be the winner of an MLB regular season game, or hundreds of other sports and current-events markets.
Here's how it works:
- Choose a Market: Select an event you're interested in, like "Will the Dodgers win the World Series" or if the Rams will win the Super Bowl.
- Buy "Yes" or "No" Shares: If you think an outcome will happen, you buy "Yes" shares. If you think it won't happen, you buy "No" shares.
- Trade as Prices Move: Market prices change throughout the day as new information becomes available. Injuries, game results, lineup news, and public sentiment can all influence probabilities.
- Exit Before the Outcome: Unlike a traditional sportsbook wager, you don't have to hold your position until the event ends. You can buy or sell shares at any time while the market remains open.
That's one reason prediction markets have become so popular. They give users the flexibility to react as a series unfolds rather than locking in a prediction before the action begins.
WHAT SPORTS ARE ON THE MENU?
- NFL
- NBA
- MLB
- NHL
- Soccer (EPL, UCL, La Liga, etc.)
- UFC and boxing
- Formula 1
- Golf
- Tennis
- Esports
- Chess
- And more!
The board turns over with the calendar, and liquidity usually pops around prime-time games and playoff runs.
OTHER EVENTS ON POLYMARKET
Sports may drive the most attention, but the Polymarket app now offers event contracts across several categories:
- Politics: Trade contracts tied to elections, government policy, and other major political developments.
- Economics: Follow markets related to inflation, interest rates, employment data, and other key economic indicators.
- Technology: Take positions on AI developments, product launches, and other stories shaping the tech industry.
- Culture: Trade contracts tied to entertainment, award shows, viral trends, and major cultural events.
- Weather & Temperature: Follow contracts linked to weather forecasts and temperature-related outcomes.
The underlying mechanics operate identically to the sports markets. You simply purchase Yes or No shares based on your personal conviction.
Contract settlement happens automatically once the real-world event reaches a verified conclusion.
Diversifying your portfolio across these non-sports sectors is a highly effective way to use your $20 trading bonus.
- 💡Quick tip for the daily grinders: posting competitive limit quotes actually earns you money through the app's liquidity rewards program.
FUNDING AND WALLETS
Polymarket US is funded in U.S. dollars, not cryptocurrency, via ACH, debit/credit card, or Apple Pay.
Once your account is verified, you can fund it using supported payment methods and trade event contracts directly in USD.
DEPOSITS & WITHDRAWALS
| Payment Method | Provider | Deposit | Withdrawal | Speed |
|---|---|---|---|---|
| Bank Transfer (ACH) | Aeropay | ✅ | ✅ | 1–3 business days |
| Debit / Credit Card | Checkout.com | ✅ | ✅ | Instant |
| Apple Pay | Checkout.com | ✅ | ✅ | Instant |
SAFETY TIPS
- Enable two-factor authentication if available.
- Keep your login credentials secure.
- Verify your payment details before depositing.
- Only use the official Polymarket US app.
TRADING FEES
When you're looking for value, every cent counts. Unlike traditional sportsbooks that build the vig into the odds, Polymarket uses a transparent fee model.
Here’s the rule of thumb:
- If you accept an existing price for an immediate trade, you're a "Taker" and may pay a small trading fee.
- If you place a limit order and wait for another user to match it, you're a "Maker"—and maker orders carry a zero fee.
Always check Polymarket's current fee schedule before trading; fees may vary by market and are subject to change.
TAXES
Profits may be taxable. Keep a simple log of deposits, fills, and settlements, and talk to a tax pro about your situation.
POLYMARKET LIQUIDITY REWARDS PROGRAM
The Liquidity Rewards Program rewards users not only for making correct predictions, but also traders who help keep markets active by placing buy and sell orders.
You can earn a share of Polymarket's daily reward pools by posting competitive limit orders in qualifying markets. In general, orders that improve pricing and add liquidity have a better chance of earning rewards.
For most users, it's simply an extra perk. As you become more active on the platform, you may have opportunities to earn additional rewards while helping create a smoother trading experience for everyone.
POLYMARKET VS KALSHI
If you've heard about Polymarket, you've probably heard about Kalshi too. The two platforms lead the prediction market space and offer similar ways to trade on real-world outcomes.
That said, they're not exactly the same. Here's a quick comparison to see how they stack up.
| Feature | Polymarket App | Kalshi |
|---|---|---|
| Welcome Offer | ||
| Regulation | CFTC-regulated event contract platform | CFTC-regulated designated contract market |
| Best For | Mobile-first users and newcomers to prediction markets | Desktop users and experienced traders |
| Mobile Experience | Excellent mobile app experience designed for on-the-go trading | Functional mobile app, but desktop remains the stronger experience |
| Market Variety | Sports, politics, economics, technology, culture, and weather markets | Sports, politics, economics, weather, financial, and event markets |
| Market Depth | Growing fast, but some categories feature fewer active contracts | Generally offers more contracts and deeper coverage across categories |
| Fees | Competitive fee structure with a smooth trading experience | Competitive fee structure with robust trading tools |
| Our Take | Best for most users thanks to its mobile-first design and larger welcome offer | Best for traders who want the widest selection of markets and deeper research opportunities |
RESPONSIBLE TRADING
Trade within your means and set personal guardrails. Responsible trading should be the norm, not a last-minute safety net. Access depends on where event-contract trading is allowed, so check what’s Polymarket legal in your location before you start trading.

TIPS TO GET STARTED ON POLYMARKET
New to prediction markets? Don't overthink it. The best approach is to keep things simple and learn as you go.
- Start with familiar markets: Sports, politics, and major news stories are usually the easiest places to begin because you already have some background knowledge.
- Think in probabilities: Contract prices reflect what the market believes is likely to happen. Understanding those probabilities can help you make smarter decisions.
- Take your time: You don't need to jump into every market. Focus on a few events you know well and build confidence from there.
- Use limit orders when it makes sense: They can help you get a better price and give you more control over your trades.
- Have a plan: It doesn't matter if you're aiming for a quick profit or holding until an event is settled, it's always good to know your strategy before entering a position.
- Stay disciplined: Like any form of trading, it's important to manage your budget and avoid making emotional decisions.
