✅ Fact checked by Andy Means

Until Polymarket and its promo code become available to US users, we recommend you check out the Kalshi promo code instead!

Sports bettors are always looking for new ways to get in on the action, and Polymarket offers exactly that. This prediction market site represents a departure from traditional online sportsbooks.

How? It implements a user-to-user model, which means pricing is determined solely by market demand. As a result, event contract prices on everything from sports to politics & pop culture remain competitive.

RotoGrinders will share the Polymarket promo code as soon as the app and signup bonus are fully live in the U.S.

Polymarket Coming to US Market Soon!

Big news—Polymarket is set to legally go live in the US soon! The operator has started a limited rollout, but its full markets and features are still pending.

RotoGrinders will keep you posted so check back for developments.

What Is the Polymarket Promo Code?

There is no Polymarket promo code at the moment. If one ever becomes available, it will likely give you a leg up when trading on the platform. And while it won’t guarantee profit, it can help users lower costs or improve liquidity when making trades.

How to Find a Verified Polymarket Promo Code

If Polymarket (and thus its promo codes) ever become legal in the US, RotoGrinders will share them with you here.

We will do the same with the Smarkets promotion code, as the platform itself isn’t even legal in the US (yet).

How to Use the Polymarket Promo Code

Using a Polymarket promo code should be easy: once you have a valid promo code, follow these steps:

1. Go to the Polymarket app or website using the links on this page (once available).
2. Hit Sign Up.
3. Register via your existing Google account or email address.
4. Enter a promo code when prompted (once one is available).
5. Follow prompts to provide more details, agree to terms, and verify account.

Polymarket Sports Bonus Offer

Currently, Polymarket does not offer promo codes or discounts for new users. However, existing users can still benefit from daily rewards on selected markets, and they can be found on the platform’s Rewards page.

A new-user bonus program could be launched in the future, so keep coming back here for any relevant updates.

Polymarket’s Legal Journey in the US

The RotoGrinders team values transparency when reviewing sites such as prediction markets. Let’s take a look at Polymarket’s journey to becoming legal in the U.S.:

• January 2022: The Commodity Futures Trading Commission (CFTC) took action against Polymarket after deeming it an unregistered derivatives exchange. Polymarket paid a $1.4 million fine and left the U.S. market, geoblocking American customers for good measure.
• January 2022-Present: Polymarket continues its global operations.
• September 2025: The CFTC gave the green light for Polymarket to offer sports event contracts in all 50 states, but we’re still awaiting the launch. The U.S. reentry was facilitated by Polymarket’s purchase of QCX, a registered derivatives exchange, for $112 million.
• November 2025: Polymarket quietly returns in the U.S. via beta testing and a limited rollout.

Polymarket’s full return seems imminent, considering that the Intercontinental Exchange (ICE)—the parent company of the New York Stock Exchange—is investing up to $2 billion in Polymarket, valuing it at about $8 billion.

ICE will become a distributor of Polymarket’s data and a partner on blockchain projects. CEO Shayne Coplan says the partnership helps bring prediction markets into the financial mainstream, combining ICE’s institutional strength with Polymarket’s tech innovation.

Additionally, Polymarket now allows Bitcoin deposits, adding to its existing support for Ethereum, Polygon, and Solana.

We’ve also seen 1789 Capital—a VC firm with Donald Trump Jr. on its advisory board — invest tens of millions in Polymarket.

Another significant step for Polymarket was its partnership with PrizePicks Predict, which helped the DFS operator expand into the prediction markets space.

While we wait for Polymarket’s return, US users have alternatives like Kalshi or actual sportsbook apps if available in their state.

Kalshi: A Legal Alternative to Polymarket

It’s a bummer that Polymarket isn’t legal in the US (yet). But the good news? (Other than the fact that Polymarket is still usable and generally well-liked) A legal, CFTC-approved alternative exists.

Enter Kalshi. Like Polymarket, this legal predictions market lets you make trades across sports, politics, pop culture, and more.

Kalshi vs. Polymarket: Key Differences

As you can see, both platforms have their strengths. The key difference is their legality, so make sure the one you pick is legal in your area before you use it. RotoGrinders conducted a complete comparison of Kalshi vs. Polymarket, so check out that guide for more details.

If you’re in the US and want to use something other than Kalshi, you can usually sign up for sportsbook promos as long as you’re in a legal sports betting state.

Polymarket Pros and Cons

As is the case with all predictions sites, and truly most things in life, there are some key positives and negatives to evaluate when getting started with Polymarket. Let’s take a look at some of the most important ones to consider.

✅ Pros:

• Competitive pricing due to user-driven model
• Unique prediction markets beyond sports, including GTA 6 event contracts and Spotify Top Song prediction markets
• Simple interface for crypto-based trading

❌ Cons:

• Not currently legal in the U.S.
• Requires cryptocurrency for deposits
• Limited offerings in some sports

Another alternative to Polymarket is Manifold, which operates under a social sports trading system.

Sports Predictions at Polymarket

Polymarket is best known for making predictions when it comes to things like politics, pop culture, and other news events, but they’ve been in the sports field for a while. In fact, the Polymarket sports market is constantly growing, giving traders more options than ever.

The Coinbase predictions market should have contracts similar to Polymarket’s!

What is a Crypto Sports Prediction?

A crypto sports prediction differs from a traditional sports bet in a couple of key ways. The most obvious stems right from the name: you’re wagering cryptocurrency instead of US dollars or whatever currency exists in the jurisdiction in question. This means prices aren’t set by a sportsbook but rather by market demand.

For example:

• If 13% of total money is placed on an outcome, its price is 13 cents per share.
• If the prediction is correct, it pays out $1 per share, ending up in an 87-cent profit per share.

This system allows fluid pricing based on real-time market sentiment.

Final Thoughts on the Polymarket Promo Code

If you enjoy sports betting but want to cut out the intermediary of a sportsbook, Polymarket could be the place for you. The user-driven model ensures fair pricing and sensitivity to movement in the market.

However, its legal status in the U.S. remains a concern, so users should weigh the risks of trading on an unregulated platform.

If this is a priority, think about playing with Kalshi! There are also sportsbooks, but if online sports betting isn’t legal in your state, try DFS or social sportsbooks.

Polymarket Promo Codes FAQs

We hope that you’ve learned plenty about getting started with Polymarket through the sections above, but if there’s anything you’re still wondering, read on.

Is Polymarket legal in the US?

Yes. The CFTC has deemed Polymarket as legal in the U.S., but the app still has to complete its full re-launch.

Is Kalshi better than Polymarket?

In short, it depends on your needs. Both platforms offer similar features, but Kalshi is fully legal in the U.S. (except for AZ, IL, OH, MA, MD, MI, MT, NJ), which may be a deciding factor.

What is the Polymarket promo code?

Currently, no Polymarket promo codes exist, but daily rewards offer extra value.

Does Polymarket have sports betting?

Polymarket lets you make predictions on sports events, so while it’s not technically betting, it lets you get in on big futures events and even specific props.

How long has Polymarket been around?

Polymarket launched in 2020 and exited the U.S. market in early 2022 but plans to make a full return soon.

Are there taxes or fees when using Polymarket?

Polymarket doesn’t charge fees in its global operations, but U.S. customers can expect a competitive 0.01% taker fee, plus any fees associated with crypto transactions. Profits won on the site are taxable over a certain amount—check out the regulations where you live and be sure to contact a professional if you’re unsure on how to proceed.

Considering that Polymarket isn’t legal in the US, we’d recommend something like the Underdog promo code instead for DFS fans.
