Featured Prediction Markets

NFL Week 8 Finale and Week 9: Bears vs Seahawks, Jaguars vs Ravens

Chicago (5-2) visits defending Super Bowl champion Seattle (4-3) on Monday, Nov. 2, at 8:15 p.m. ET on ESPN. Caleb Williams is back after missing three games, and Sam Darnold has thrown eight touchdowns and eight interceptions for the Seahawks.

Thursday’s game changed on Sunday. The Ravens lost 36-10 at Buffalo, and Lamar Jackson will have right thumb surgery and go on injured reserve. Baltimore (4-4) hosts Jacksonville (5-2) on Thursday, Nov. 5, at 8:15 p.m. ET on Prime Video.

Check the current price for each game in the Polymarket US app before placing a trade, since prices move with injury news.

Midterm Elections: Chamber Control Contracts on Polymarket US

Election Day is Tuesday, Nov. 3. All 435 House seats and 35 Senate seats are on the ballot, and a party needs 218 House seats for a majority.

Polymarket US has listed contracts on control of each chamber and on individual races. Check the app for the contracts available to you.

Remember: each contract settles under its own market rules, and the rules name the source that decides the result. Close races can take days to call, so a position can stay open well after Nov. 3. Also, a contract on which party wins a race and one on seat totals settle on different conditions, so read the resolution criteria before you trade.

My First Look at Trading on Polymarket

After depositing $10 with Apple Pay, I checked out the Patriots-Seahawks market for the September 9 season opener. New England was priced at 38¢ to win, meaning the market gave the Patriots roughly a 38% chance.

Here's what that looked like: $9.50 would buy 25 Patriots contracts at 38¢ each, plus about 41¢ in taker fees. A Patriots win would've paid out $25, while a loss would leave those contracts worth nothing.

Seattle ended up winning 13-10, so anyone who held those Patriots contracts through the final whistle lost their position.

But you don't necessarily have to wait for the result. If the price had climbed from 38¢ to 55¢, selling those 25 contracts would have returned $13.75 before fees. After the buying and selling taker fees, that would leave about $3.41 in profit, assuming both orders filled at those prices.

And with the INSIDER promo code, your $10 deposit plus the $25 trading bonus gives you $35 to work with once credited. Just remember that extra trading credit doesn't change the odds, and the bonus itself isn't withdrawable cash.

How To Sign Up With The Polymarket Promo Code

Claiming the Polymarket promo code starts during registration. The important part is entering the code before you finish signing up, then making your first qualifying deposit within seven days.

Here's how to do it:

1. Open the Polymarket US signup link. Use the Polymarket links on this page to get started. Make sure you're registering for Polymarket US, not the separate international platform.
2. Create your account and enter the promo code. Follow the signup prompts, which include Google or Apple ID sign-in options. Enter INSIDER in the referral or promotional code field during onboarding. If you follow a promotional link, check whether the code has already been applied.
3. Complete identity verification. Polymarket asks for your date of birth, phone number, legal name, address and Social Security number. Most users are verified automatically. If additional checks are needed, you may have to upload a government-issued ID and complete a selfie check. You'll need approval before depositing or trading.
4. Confirm your location. You must meet Polymarket US's location requirements and pass the applicable location checks. Being a resident of an eligible state isn't enough if you're trying to trade from a restricted location.
5. Deposit at least $10. Make your first qualifying deposit within seven days of onboarding. Polymarket supports debit cards, ACH bank transfers, Apple Pay on iPhone, and other eligible funding methods. Depositing more than $10 doesn't increase this offer's $25 credit.
6. Check for the $25 trading bonus. Once Polymarket confirms your deposit meets the promotion's requirements, the credit is applied within 24 hours. The bonus is separate from withdrawable cash, so check your account's promotional balance or available trading funds rather than assuming your cash balance will read $35.
7. Choose your first market. You can trade on an NFL game, championship futures or other available events. Just remember that trading fees and contract prices affect how much you can buy with your available funds.

One thing to remember: The seven-day deadline applies to your qualifying first deposit, not to placing a trade. Promotional credit has its own expiration rules, so check the deadline displayed for your offer.

How The Polymarket $25 Bonus Works

With promo code INSIDER, eligible new users who deposit at least $10 receive $25 in promotional trading credit. The first deposit must be made within seven days of onboarding, and the bonus is credited within 24 hours after Polymarket confirms the requirements have been met.

You don't need to place a trade to qualify. Once awarded, the credit can be used toward eligible positions and trading fees. Polymarket uses your existing cash balance before promotional credit.

Here's the part that matters: the $25 bonus itself isn't withdrawable cash. Eligible proceeds generated through trading may become withdrawable, but the promotional credit remains subject to Polymarket's restrictions. Your original deposit must also clear before funds tied to it can be withdrawn.

Check the expiration attached to your offer before deciding when to trade. Any unused credit is subject to the applicable deadline.

How The Polymarket Referral Program Works

The INSIDER code is the welcome offer we're covering here, but Polymarket US also has a separate Refer-A-Friend program for existing customers.

Here's how it works: share your Polymarket username as a referral code, and your friend can enter it when creating an account. Once they complete signup and deposit at least $10, you both qualify for $25 in promotional trading credit.

You can earn rewards for up to 50 qualifying referrals, with credits issued within seven days after Polymarket confirms the requirements have been met. You don't need $10,000 in lifetime trading volume to participate.

Keep in mind: Referred new users can't also claim the separate Deposit Incentive Program on the same account, so don't expect to combine the two offers.

Trade With Polymarket's $25 Offer

Once you've claimed the Polymarket promo code INSIDER offer, the next question is where to use your $25 trading credit.

Football and basketball carry the sports board this week, and the Super Bowl and NBA tables above are the longer holds. Keep in mind the promotional credit isn’t withdrawable cash and has its own expiration, so check the deadline shown for your offer.

🏀 NBA Cup Group Play

NBA Cup group play runs on Fridays from Oct. 30 through Nov. 27, with two more group nights on Tuesday, Nov. 24, and Wednesday, Nov. 25. Group games count toward the 82-game regular-season schedule, and the Dec. 11 championship game in Indianapolis does not. On Friday, Nov. 6, the Celtics visit the Hornets and the Wizards visit the Hawks, both at 7 p.m. ET.

Top Basketball Markets

• Game Winners: A single-game contract settles on that night’s result, which suits a Cup night without a long hold.
• NBA Champion: The champion table above shows how the market prices each title contender.
• Cup Status: Group games count in the regular-season standings and the championship doesn't, so check which games a contract settles on.

🏈 NFL Futures Markets

Polymarket lets you trade on Super Bowl winners, conference champions, division races, MVP, and other season-long NFL markets.

Top NFL Markets

1. Super Bowl Winner: The long-haul hold. Prices move slowly outside of major injuries and losing streaks, so it's about picking an entry rather than trading it week to week.
2. Conference Champions: A way to back a team without needing it to win the Super Bowl. The Yes price will usually be higher than its Super Bowl-winning price, which means a smaller potential payout per contract.
3. Division Winners: The steadiest read on the board, and it reprices fast when a starting QB goes down.
4. NFL MVP: A quarterback market, mostly. Early value sits with a healthy QB whose team looks ready to take a step up.

Pro tip: Don't overreact to one early-season result. Injuries, starting quarterback changes and a team's performance over several weeks can have a bigger effect on futures prices. It's worth checking how much the market has already adjusted before buying.

How Sports Contract Prices, Fees and Exits Work on Polymarket

Polymarket is an exchange where buyers and sellers trade event contracts. There, prices come from the orders on the book, not from a number the platform sets.

Trading has costs. Taker orders pay a fee, and the gap between buy and sell quotes affects what a position returns. Maker orders that rest on the book carry no trading fee. A sale before settlement depends on liquidity and the price buyers will pay.

Here's what you need to know:

It's also worth knowing that Polymarket US operates under federal derivatives regulation, and that affects where users can trade and which requirements apply.

How Sports Markets Actually Work

Polymarket allows users to trade on the probability of an outcome happening. That could be the winner of an NFL game, or hundreds of other sports and current-events markets.

Here's how it works:

• Choose a Market: Pick an event you’re interested in, like whether the Rams will win the Super Bowl or the Bills will win the AFC.
• 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: You can try to sell your contracts before an event ends, rather than holding until settlement. The price you receive depends on available buyers.

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.

Here are a few NFL games to follow with your Polymarket trading credit:

Before placing a trade, check that the matchup and contract type are available on Polymarket US, and compare the current price with what you're willing to pay.

What Is Polymarket?

The Polymarket app is a CFTC-regulated prediction market platform that lets you trade on the outcomes of real-world events.

Rather than taking a fixed price, you 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 a 25% chance.
• A Yes share trading at $0.60 implies a 60% chance.
• A Yes share trading at $0.80 implies an 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. Polymarket US operates through a CFTC-regulated designated contract market, allowing eligible U.S. customers to trade event contracts under federal derivatives oversight.

That doesn't mean every user can access every market from every location. Polymarket applies eligibility, identity verification and geographic restrictions, and the legal treatment of certain event contracts continues to be disputed in some states.

Before registering, confirm you're at least 18, check the current restrictions for your physical location and complete the required identity verification. Access to the platform and eligibility for a particular promotion aren't necessarily the same thing.

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 is for sports fans, news followers or people who like reality TV shows (Big Brother, Bachelor, etc.). Polymarket offers the ability to trade on outcomes for all those categories, with 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.

Other Events On Polymarket

Sports drive the most attention, but the Polymarket app now offers event contracts across other 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 TV Shows/Movies, award shows, viral trends, and major cultural events.
• Weather & Temperature: Trade on 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.

Expert tip: Resting limit orders can qualify for liquidity rewards in certain markets. Check the requirements before placing an order, since rewards aren't guaranteed.

Funding And Wallets

You can fund Polymarket US in U.S. dollars without setting up a crypto wallet. The platform supports debit cards, ACH bank transfers, Apple Pay on iPhone, PayPal, Venmo and wire transfers. USDC is also available on iPhone where supported.

Deposits & Withdrawals

Important: instant buying power doesn't mean an instant withdrawal. Even if you can trade right after a deposit, you'll usually have to wait until that deposit has fully cleared before withdrawing cash or eligible trading proceeds.

Trading Fees

Polymarket US charges trading fees differently from a traditional sportsbook. Rather than building a standard sportsbook margin into fixed odds, the exchange matches buyers and sellers and charges fees based on how orders execute.

Here's what you need to know:

• Taker orders: If your order trades immediately against an existing quote, you pay a fee. The amount depends on the contract price and number of contracts. Fees are generally highest around a 50¢ price and lower near either end of the range.
• Maker orders: If you place a limit order that rests on the order book until another trader matches it, you don't pay a maker trading fee. Eligible high-volume traders may also qualify for rebates.

Keep an eye on the bid-ask spread, too. Even a fee-free order isn't automatically a good deal if you're buying at a price you don't like.

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

Polymarket US offers liquidity incentives for traders who place resting orders in eligible markets. These orders help provide prices and available contracts for other users, whether or not every order gets filled.

The rewards depend on the applicable market and incentive terms, so placing a limit order doesn't automatically guarantee a payout.

Polymarket also has a separate maker-rebate structure for qualifying executed orders. Since October 19, 2026, maker rebates have depended on trading volume. Accounts with less than $10 million in qualifying maker volume won't receive a maker rebate, although maker orders will still carry no trading fee.

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.

Responsible Trading

Responsible trading matters. Set a budget before your first trade, not after a losing one. Contracts can settle at zero, meaning you can lose the entire amount committed to a position.

If trading starts affecting your finances or becomes difficult to control, confidential support is available through the National Council on Problem Gambling:

• Chat online: Visit 1800myreset.org to find support resources.
• Call or text 1-800-MY-RESET for the National Problem Gambling Helpline.

Customer Support

Need help with your Polymarket US account? Start with the support options provided by the platform.

• In-app support: Check the app's help and support options for account-specific issues.
• Email: support@polymarket.us for questions about verification, deposits, withdrawals or trading.
• Help Center: Visit the Polymarket US Help Center for information about payments, account access, fees and market rules.

If your $25 bonus hasn't appeared, include your account email, deposit date and the offer you used. Never send your password, Social Security number or full payment information through an unofficial support channel.

History Of Polymarket

• 2020 launch: Event trading across sports, elections, and macro prints.
• January 2022 regulatory issue: Polymarket was fined $1.4 million by the Commodity Futures Trading Commission for offering unregistered options and swap contracts, forcing the platform to block U.S. traffic while it pursued a licensed framework to return legally.
• July 2025: Polymarket closed a $112 million acquisition of QCEX, including the CFTC-designated exchange QCX LLC and clearinghouse QC Clearing LLC — the licensed vehicle for its U.S. return.
• October 2025: Intercontinental Exchange (ICE, NYSE parent) said it will invest up to $2B in Polymarket, implying a multi-billion valuation and signaling a push to take event markets mainstream. Polymarket also outlined a licensed derivatives exchange + clearinghouse route for a U.S. return, pending an official launch date.
• November 2025: The CFTC amended QCX LLC's designation order, clearing the way for intermediated trading through the entity now doing business as Polymarket US
• March 19, 2026: MLB named Polymarket its exclusive Official Prediction Market Exchange Partner. The deal gives Polymarket access to MLB marks, logos, and official league data through Sportradar. On the same day, MLB signed a memorandum of understanding with CFTC Chairman Michael Selig to share integrity information. As part of the agreement, certain market types are off limits, including individual pitches, manager decisions, and umpire performance.
• March 2026: Polymarket was in beta testing, but still allowed users to use the invite codes to skip the line and unlock early bonuses.
• May 2026: The Polymarket waitlist is over. Users can register to the Polymarket app with the original invite code or a new promo code like INSIDER

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.
