Polymarket Invite Code ACTION

This generous welcome offer helps Polymarket compete with established prediction market apps like Kalshi. In fact, Polymarket's signup bonus is exactly double what the Kalshi promo code  currently offers.

Stay tuned to The Action Network for the latest updates as we continue to track Polymarket's beta testing phase and expanding prediction markets!

Why Is a Polymarket Invite Code So In-Demand?

Polymarket's return to the U.S. has generated massive excitement, leading to a waitlist that has already 1M+ users. The platform is currently in a limited beta phase, meaning not everyone can sign up freely. This exclusivity allows Polymarket to manage its user growth, ensure regulatory compliance with the CFTC, and fine-tune the user experience before a full public launch.

An invite code, like ACTION, serves as a 'fast pass,' allowing users to skip this extensive waitlist entirely. Without a valid code, new users are placed in a queue with no clear timeline for when they'll gain access.

This makes verified invite codes the single most sought-after key for accessing Polymarket's unique trading markets in the U.S. right now.

How to Use the Polymarket Invite Code

1. Download the official Polymarket app using the links on this page.
2. Open the app, tap "I have an invite code," and enter promo code ACTION.
3. Follow the prompts to create a new account via your Google or Apple account.
4. Link a deposit method.
5. Deposit at least $20 and make a qualifying first trade to collect the $20 bonus.

While Polymarket is legal in all 50 states due to its CFTC status, the promo is limited to users in: AL, AK, AR, CA, CO, CT, DE, FL, GA, HI, ID, IN, IA, KS, KY, LA, ME, MN, MS, MO, NE, NH, NM, NY, NC, NV, ND, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, VA, WA, WV, WI, WY, DC.

States such as AZ, IL, MA, MD, MI, MT, NJ, NV and OH restrict the Polymarket promo code due to state legal challenges against prediction market apps.

Terms & Conditions

When claiming a bonus like Polymarket's, you should understand exactly what you're signing up for:

• Only valid for users with a legal residential address in: AL, AK, AR, CA, CO, CT, DE, FL, GA, HI, ID, IN, IA, KS, KY, LA, ME, MN, MS, MO, NE, NH, NM, NY, NC, ND, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, VA, WA, WV, WI, WY, DC.
• Unlike with sportsbooks, you can't be a visitor in one of the above states. You must legally live there.
• Not valid for users in: AZ, IL, MA, MD, MI, MT, NJ, NV and OH.
• You must be 18+.
• You must deposit at least $20.
• The $20 bonus is not withdrawable—you must make qualifying trades, and the profits from your trades become withdrawable.

How to Get Off the Polymarket Waitlist

To get off the Polymarket waitlist, just enter this invite code: ACTION.

Polymarket is finally live in the U.S., but only on a limited basis.

Users are able to get on the waitlist by entering their phone numbers. Unfortunately, the waitlist is super long (1 million+ users) and texts from Polymarket about getting off the waitlist don't actually grant access.

Some users are turning to Reddit to look for Polymarket invite codes, but Reddit users are just sharing their Polymarket referral links in an attempt to move up the waitlist themselves. These links only direct you to the Polymarket waitlist page, and again, don't actually grant access to the app.

The only way to get off the waitlist is by using an invite code such as ACTION Our code not only grants early access but also unlocks a $20 deposit match, so claim today!

Polymarket may decrease this welcome offer when it fully launches in the U.S., so take advantage today.

What Event Contracts to Trade Today, April 03, 2026

With Polymarket's current focus on live sports trading during the U.S. beta, there are plenty of daily markets to get in on. If you use our invite code ACTION, you can skip the waitlist and start trading shares on the following matchups today:

Market Category	Live Event Contract	Current odds	Trader Strategy
⚾ MLB Early Slate	Mets vs Cardinals	Mets 61% Cardinals 40%	Buy "Yes" shares early if you project a strong performance from New York's starting pitching, or wait for live-trading opportunities to sell if St. Louis jumps to an early lead.
🏀 NBA Primetime	Celtics vs Heat	Celtics 66% Heat 35%	Monitor the injury report closely leading up to the 7:30 p.m. ET tip-off. Look for arbitrage opportunities on "No" shares if any late-scratch news hits the wire for Boston.
🏀 NBA Late Night	Spurs vs Warriors	Spurs 88% Warriors 13%	Trade the live order book dynamically. If San Antonio hits early shots and pulls ahead, you can buy discounted Golden State shares in anticipation of a late-game comeback.

What Is Polymarket?

Polymarket is a federally regulated prediction market that allows American participants to trade on the outcome of real-world events.

Unlike the global version of the platform, which operates as a decentralized crypto entity, the U.S. exchange functions as a Designated Contract Market (DCM) overseen by the Commodity Futures Trading Commission (CFTC). This transition to a regulated framework means the platform operates with the same legal protections and oversight as major financial exchanges like the NYSE or CME, offering users a secure environment to trade "event contracts."

How Does Polymarket Work?

The core mechanic of Polymarket in the U.S. is a peer-to-peer exchange where users trade against one another rather than against a centralized bookmaker.

When you purchase an event contract, you are buying a share of a future result; for instance, a "Yes" share on a specific event might cost $0.65, reflecting a 65% market probability of that outcome. If your prediction is correct, the share settles at exactly $1.00, providing a clear profit margin.

Because Polymarket generates revenue through transparent trading fees rather than user losses, it eliminates the "house vs. player" conflict of interest, ensuring that successful traders are never limited or banned for their performance.

While the underlying technology utilizes blockchain for secure settlement, the U.S. experience is designed for mainstream accessibility.

Users are required to undergo standard "Know Your Customer" (KYC) identity verification, and accounts are funded through regulated financial channels like bank transfers or USDC stablecoins.

This model preserves the platform's reputation as a "global truth machine"—aggregating the collective knowledge of thousands of participants into real-time data—while providing the regulatory peace of mind necessary for the American financial landscape.

Timeline of Events for Polymarket's Return

Here's a look at Polymarket's journey in/out of the U.S., in reverse chronological order:

• March 23, 2026: Infrastructure Upgrade. Polymarket acquires the DeFi infrastructure startup Brahma. The move is designed to simplify the "crypto plumbing" of the U.S. app, moving toward a UX where blockchain elements like wallet management are invisible to the consumer.

• March 2026: Polymarket reaches a projected valuation of $20 billion, fueled by record volumes during the 2026 World Cup and U.S. midterm primary markets.

• January 26, 2026: MLS "Real-Time Sentiment" Integration. Major League Soccer (MLS) partners with Polymarket to integrate live trading data into match broadcasts. This allows fans to see real-time win probabilities—driven by active market trades—during live games on Apple TV.

• December 2, 2025: Regulated Beta Launch. Polymarket US begins legally onboarding American users under CFTC oversight. While technically live, the platform remains in beta testing, using a waitlist to manage the transition from a decentralized global model to a regulated U.S. framework.

• October 2025: Institutional Integration. NYSE-parent ICE invests $2 billion into Polymarket. Simultaneously, Polymarket enables direct Bitcoin deposits, broadening its reach beyond the USDC ecosystem.

• August 26, 2025: Political Strategy. 1789 Capital leads a strategic funding round, and Donald Trump Jr. joins the Polymarket advisory board to help navigate the U.S. regulatory and political landscape.

• July 9, 2025: The Regulatory Breakthrough. Polymarket acquires QCX, LLC for $112 million, securing the "Designated Contract Market" (DCM) status required by the CFTC for legal U.S. operations.

• January 3, 2022: The Exit. Following a $1.4 million settlement with the CFTC over unregistered swaps, Polymarket offboards all U.S. users and shifts to a global-only model.

• June 2020: The Beginning. Founder Shayne Coplan launches Polymarket as a decentralized, Polygon-based exchange.

Polymarket App Review

The Polymarket mobile app, available for both Apple and Android devices, successfully packs the depth of its desktop version into a clean, minimalist interface. It trades the "busy" feel of a traditional sportsbook for a streamlined trading dashboard, featuring smooth navigation and live price charts that update in real-time.

While the app excels in speed, there are a few structural differences that sports fans should keep in mind. Unlike most betting apps where player props are front-and-center, on Polymarket, you typically have to dig into each specific game to find individual performance contracts.

Additionally, the platform’s approach to "parlays" is more structured; instead of the flexible Combos found on Kalshi, Polymarket leans into custom-built parlays. These pre-packaged markets ensure higher liquidity and more stable pricing, but they offer less customization for those used to building their own long-shot tickets.

Event Contracts: What You Can Trade at Polymarket

In early 2026, the U.S. version of the app is still rolling out features compared to the global site.

But here's a look at what you can trade at Polymarket:

Primary Focus: Sports and Live Trading

Right now, the beta mobile app is heavily optimized for Sports. This is the platform's primary entry point for U.S. users, especially with the current "March Madness" season. Unlike traditional sportsbooks that offer static odds, Polymarket operates as a live exchange where you can trade positions as a game unfolds.

• Available Markets: You'll find standard Moneylines, Spreads, and Over/Unders (Totals).

• Prop Markets: Player-specific performance contracts (e.g., "Will player X score 20+ points?") are also highly active.

• Live Trading: This is the app’s standout feature. Because it is an exchange, you can "buy" a team when they are down early and "sell" your shares for a profit the moment they take the lead—all before the final whistle.

It's nice that Polymarket displays its odds in American sportsbook format, meaning you don't always have to rely on a prediction market odds converter.

The Powerhouse Categories: Politics and Crypto

While sports are the focus for the U.S. app's expansion, Politics remains the historical engine of Polymarket’s massive trading volume. Globally, political markets (like the 2024 and 2026 elections) have seen billions in volume, often outpacing all other categories combined.

• Politics: In the U.S. version, political markets are gradually being introduced under strict CFTC oversight. These include primary outcomes, legislative passage probabilities, cabinet appointments, and midterm winners. In general, Polymarket has seen as ton of trading volume on the U.S. vs. Iran conflict.

• Crypto: This is the second-largest volume driver. Traders use Polymarket to hedge their portfolios by trading on Bitcoin price targets, Ethereum gas fees, or the timing of major protocol upgrades.

Historically, Polymarket has seen its biggest volume in Politics. However, following its transition to the regulated U.S. market, it is expected to see a massive jump in Sports volume. We have already seen this trend with competitors like Kalshi; as these platforms become legal and easy to use with USD, sports fans are flocking to the exchange model for its better pricing (lower "vig") and the ability to trade out of positions early.

Other Emerging Markets

Beyond the big three (Sports, Politics, and Crypto), Polymarket is expanding into "Macro" and "Culture" categories that provide a pulse on the world:

• Economy: Federal Reserve interest rate decisions, inflation (CPI) data, and GDP growth.

• Culture: Award shows like the Oscars or Grammys, Spotify streaming records, and box office results.

• Weather & Science: Hurricanes, global temperature records, and even breakthroughs in fields like AI or space exploration.

Polymarket vs. Traditional Sportsbooks

To the untrained eye, Polymarket looks similar to traditional sports betting. But in practice, it has some pretty distinct differences from the best sportsbooks:

✅ Feature	🔵 Polymarket (Prediction Market)	🏈 Traditional Sportsbook
Who You Play Against	Other Users (Peer-to-Peer)	The House (Bookmaker)
Pricing Model	Market-driven share prices ($0.01–$0.99)	Fixed odds (e.g., -110, +150)
Fees / "Vig"	Transparent Taker Fee (near 0% to 1.8%)	Hidden "Juice" (typically 5%–10%)
Flexibility	Trade in and out of positions 24/7	Limited early cash-out features available
Winning Limits	No limits for winning too much	Successful bettors are often limited or banned
Regulation	Federal (CFTC Oversight)	State-by-State (Gambling Commissions)
Market Scope	Sports, Politics, Crypto, Culture, Econ	Primarily Sports
Account Funding	Bank Transfer, Card, or USDC	Bank Transfer, Card, PayPal, Cash

At a traditional sportsbook, you're fighting against an algorithm designed to ensure the house wins.

At Polymarket, you're trading in a transparent financial market. Because the pricing is determined by the "wisdom of the crowd" rather than a bookmaker's margin, the implied probabilities are often much more accurate and the potential payouts are significantly higher for the user.

Of course, there are some caveats to the general rules. For instance, Polymarket and other prediction market sites are facing legal action from certain states despite their CFTC status.

Is Polymarket Legal in the US?

While Polymarket is federally legal, individual state regulations still apply. Currently, the platform and our Polymarket promo code ACTION are available in 41 states and Washington, D.C.

Due to local legal challenges regarding prediction markets, users in the following states currently cannot access the app or the promo: Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, New Jersey, Nevada, and Ohio.

If you are outside of those restricted states, you are fully in the clear to sign up, verify your identity (KYC), and start legally trading!

Is Polymarket Safe?

Yes, Polymarket is safe! Safety and reliability are the cornerstones of the new Polymarket framework in the US.

CFTC Status

Unlike the early days of unregulated crypto platforms, Polymarket US operates as a Designated Contract Market (DCM), meaning it is subject to rigorous oversight by the Commodity Futures Trading Commission (CFTC). This federal regulation requires the platform to adhere to strict standards regarding financial integrity, consumer protection, and the prevention of market manipulation.

When you trade on Polymarket US, you're participating in a legal financial market backed by the same type of regulatory "peace of mind" found in traditional U.S. stock exchanges.

Protected Customer Funds

One of the most significant security features of the U.S. version is the segregation of customer funds. By law, Polymarket US cannot use your deposits for its own operational expenses. Your funds are held by a regulated clearinghouse and are legally protected, ensuring that your balance is always available for withdrawal.

Secure User Accounts

Furthermore, the platform utilizes institutional-grade encryption and mandatory Two-Factor Authentication (2FA) to protect user accounts. Because the U.S. app requires identity verification (KYC), it also provides a layer of protection against fraud and unauthorized access that anonymous platforms simply cannot offer.

Reliable Payouts

Reliability in payouts is another area where Polymarket US excels. Because the platform uses official league data (such as MLB and NHL feeds) and verified news sources for contract resolution, there is no "human error" or "house bias" when determining a winner.

Once a market is resolved, the smart contract technology on the backend settles the trades instantly, and funds are made available for withdrawal to your linked bank account. This transparent, code-based settlement ensures that if you win a prediction, your payout is guaranteed and processed with the speed and reliability of a modern financial institution.

Additionally, Polymarket is joining other prediction market apps to prevent insider trading, further ensuring the integrity of payouts.

Banking at Polymarket US

In the transition to a regulated U.S. framework, Polymarket has overhauled its banking system to look and feel like a standard American brokerage.

The platform has moved away from the "crypto-only" hurdles of its past, integrating with traditional financial networks to ensure that depositing and withdrawing funds is a seamless experience for every user.

For another crypto-heavy prediction market app, check out the Crypto.com referral code.

Deposit and Withdrawal Options

Funding your account is now as simple as linking your bank. Through a partnership with Plaid, Polymarket US allows you to connect your checking or savings account for instant ACH transfers. If you prefer more immediate methods, you can use a Visa or Mastercard debit card to fund your account instantly.

For users who already hold digital assets, Polymarket remains a leader in the crypto-finance space. You can deposit USDC directly via the Polygon network. Additionally, the platform added support for direct Bitcoin (BTC) deposits.

When you deposit, your funds are held as USDC—a stablecoin pegged 1-to-1 with the U.S. Dollar—ensuring your balance doesn't fluctuate with the volatile crypto market.

Withdrawals follow the same path: you can send your winnings back to your bank account or to an external crypto wallet with a few taps.

Credit cards are not compatible with Polymarket U.S., so consider deferring to the best credit card sportsbooks as an alternative.

Understanding the Fee Structure

Polymarket was historically "fee-free," but in early 2026, it introduced a transparent Taker Fee model to improve market quality. These fees don't go to "the house" as profit; instead, they fund the Maker Rebate Program, which pays professional traders to keep the markets liquid and the spreads tight.

The fee you pay is dynamic, meaning it changes based on the probability of the event. Fees are highest when a result is a "toss-up" (50% probability) and drop significantly as an outcome becomes more certain (approaching 1% or 99%). This ensures that you aren't overcharged for trading "sure things."

Feature	Details	Cost / Fee
Bank Deposits (ACH)	Instant link via Plaid	$0 (Free)
Debit Card	Visa and Mastercard	$0 (Platform side)*
Crypto Deposits	USDC (Polygon) & Bitcoin (Direct)	$0 (Network fees apply)
Withdrawals	Transfer to Bank or Crypto Wallet	$0 (Free)
Sports Trading	Dynamic fee based on probability	0.01% – 0.75% (Peak)
Politics & Finance	Dynamic fee based on probability	0.04% – 1.00% (Peak)
World Events	Geopolitical and Global News	Permanently Fee-Free

Polymarket Rewards Program

With Polymarket moving away from its simple "no-fee" model, it uses its fee revenue to fund an active Rewards and Rebates ecosystem. The most prominent feature is the Maker Rebate Program, which pays users daily in USDC for providing liquidity.

By placing "limit orders" (orders that aren't filled immediately), you essentially act as a market maker; when another trader takes your price, Polymarket rewards you with a portion of the transaction fee. This system ensures that the markets remain deep and the spreads stay tight, which is especially beneficial for high-volume sports and crypto traders.

Beyond professional rebates, the platform has recently expanded its Referral Program to all users with at least $10,000 in trading volume. This program has a relatively high barrier to entry but allows you to earn a direct cut of the trading fees generated by anyone who signs up using your unique link—offering 30% for direct referrals and 10% for secondary referrals for their first 180 days on the platform.

Additionally, for major events like March Madness, Polymarket frequently rolls out "Liquidity Rewards" pools, sometimes exceeding $2 million, to incentivize active trading during peak tournament hours.

Polymarket's Key Partnerships

In an attempt to compete with Kalshi and become a major player in the US prediction market space, Polymarket has established multiple key partnerships.

One of the most recent was with the MLB—a huge multi-year deal was signed in March 2026 to make Polymarket the exclusive prediction market of baseball. While other prediction market apps are still able to offer MLB markets, Polymarket has exclusive rights to use official MLB team names, logos, etc. Additionally, this partnership includes access to official league data via Sportradar, ensuring all contracts are settled using the same verified, real-time metrics used by the league itself.

Polymarket also has partnerships with the following leagues:

• NHL
• UFC
• MLS
• BLAST (Esports)

Polymarket vs. Kalshi

As Polymarket works toward a regulated return to the U.S., it’s often compared to Kalshi—the only fully live, CFTC-regulated exchange currently available to retail users.

Polymarket has taken a major step by establishing a CFTC-registered Designated Contract Market (DCM) entity in the U.S., signaling a shift from its crypto-native roots toward a more traditional, regulated exchange model. However, the platform is still in a limited rollout phase, meaning access is not yet as widely available or fully built out as Kalshi’s existing product.

Feature	🔵 Polymarket (U.S.)	🟢 Kalshi
Regulation	CFTC-registered DCM (via QCX LLC)	CFTC-regulated (DCM)
Availability	Limited rollout / early access	Fully live for retail users
Market Focus	Expanding (sports currently leading rollout)	Economics, weather, financial events
Platform Stage	Early-stage U.S. buildout	Established U.S. exchange
Trading Model	Exchange-based (in development)	Event contracts ($0.01–$0.99)

Polymarket Customer Service Review

Polymarket US keeps its support system transparent and highly accessible. Between detailed guides and multiple contact methods, there is always a way to get the help you need without jumping through too many hoops. Here are the primary ways to resolve an issue or get in touch with the team:

• Help Center: The best starting point for finding quick, detailed answers on how to verify your ID, how specific game payouts are calculated, and general platform rules.
• Polybot (24/7 AI Assistant): Available directly in the app, this bot is surprisingly good at handling technical questions and checking on your account status in real-time.
• Live Representatives: If Polybot can’t solve your problem, you can easily bypass the AI and request a live human rep at any time.
• Discord Community: Polymarket is highly active on Discord, making it a great place for more hands-on help where you can open a direct support ticket.
• Email Support: If you prefer the traditional route, you can always send their support team an email to get your issue resolved.

Responsible Trading at Polymarket US

As a federally regulated exchange, Polymarket US operates under much stricter safety standards than its international counterpart. The platform is overseen by the CFTC, which requires robust tools to protect users and maintain market integrity.

Technological guardrails launched in March 2026 that proactively block insiders—such as athletes, coaches, and political candidates—from trading on events they can influence. Users also have access to a whistleblower tool directly on market pages to flag any suspicious or manipulative activity.

Beyond institutional oversight, the app includes personal features to help you manage your trading. You can set custom deposit limits to control your spending or use the self-exclusion tool to take a temporary break from the platform.

Because Polymarket is built on transparency, every contract clearly lists its Resolution Source before you trade, ensuring you know exactly which official data will be used to determine the winner. This professional, "finance-first" approach ensures that trading remains a data-driven experience rather than a high-risk gamble.
