Kalshi Referral Code & Review 2025 - Get a $10 Bonus with Code WSN

Kalshi is an online trading platform. It works like a betting exchange, with players betting against each other (rather than the house) on various topics, including sports. Since it’s not a regular sportsbook, Kalshi is legally available in all 50 states.  

My Kalshi review delves into exactly how Kalshi works, how it compares to a more traditional sports betting experience, how the Kalshi referral code WSN works, how to claim your Kalshi bonus and more.

What Is Kalshi? 

Kalshi is an American financial exchange market that allows players to trade “event contracts” for categories such as politics, weather, and sports. Trading event contracts is very similar to placing bets, only you are betting against other Kalshi users rather than the house.

Kalshi is regulated at a federal level by the Commodity Futures Trading Commission (CFTC), allowing it to operate legally nationwide. 

How Does Kalshi Differ From Other Sports Betting Platforms? 

Kalshi is not a sportsbook; it operates as a federally regulated financial exchange offering "event contracts." This core difference fundamentally changes how users bet and how payouts are determined.

Kalshi functions like a stock market for predictions, where you trade the probability of an outcome against other users. Sportsbooks operate like a traditional casino, where you bet directly against the established odds set by the platform.

Kalshi Referral Code WSN for $10 Bonus

Kalshi offers a $10 sign-up bonus when you create a new account using referral code WSN and spend $100 on event contracts. I opted into this bonus myself, and I’m showing you how to follow in my footsteps. 

How to Claim the Kalshi Promo 

It took me just five minutes to sign up with Kalshi, confirm my information, and deposit funds. 

Here’s what I did to get started: 

1. I used the WSN referral link to visit Kalshi’s website and clicked “Sign Up” in the top-right corner. The Kalshi promo code WSN is automatically applied.

2. You can sign up using your Google account, Apple ID, or email address. I clicked “Continue with Email,” typed my email, created a new password, and clicked “Continue” to proceed. 

3. I opened my inbox, looked for a new email from Kalshi, and entered my one-time code on their website. 

4. I clicked “Continue,” entered my birthday, typed my cell phone number, and confirmed my SMS verification code. 

5. I entered my first name, last name, residential address, and nine-digit Social Security Number before clicking “Submit” to finalize my account. 

6. I clicked “Add Funds,” chose my payment method, and followed their instructions to fund my account with $100 upfront. Seconds after refreshing the site, I saw $100 in my balance. 

While it’s easy for beginners to get started with Kalshi, their bonus doesn’t come until later on. I had to spend $100 on trades before claiming my $10 bonus. 

Kalshi Referral Code Terms & Conditions

Kalshi requires that all users be 18+ years of age and a U.S. citizen before signing up with their platform. You must deposit cash at least once and spend $100 on event contracts before getting $10 in bonus money. 

Most traditional sportsbooks give you some kind of bonus up front, like bonus bets or a deposit bonus.

Kalshi is different, with a smaller bonus available only after you’ve already spent $100 on the site and less of an emphasis on sports betting bonuses in general.

Use Kalshi promo code WSN at sign up for a $10 bonus when you trade 100 contacts.

More Promos at Kalshi 

Bonuses and promos aren’t really a thing at Kalshi, at least in the same way as traditional sportsbooks. However, in addition to the welcome bonus, you can claim a referral bonus when you get friends to sign up and play on Kalshi. 

There’s also a Bug Bounty program, which rewards users for reporting bugs or ambiguities in the pre-listed markets, but this is more of a security and user experience feature than a bonus.

Kashi Refer a Friend Bonus

When your friend makes a new account with your referral code and buys at least 100 event contracts, you’ll both get a $10 bonus. You must make your first trade before unlocking the ability to refer your friends

Each event contract can be priced between $0.01 and $0.99 based on the probability of the event taking place, although I rarely saw them priced that low. As long as your friend buys at least 100 contracts, the value of each one doesn’t matter - you’ll both qualify for a free reward. 

For that reason, it’s easy to select contracts that make financial sense in the context of this reward. 

To get started, I opened the main menu and clicked “Invite A Friend.” 

I clicked “Share Link,” sent it to a coworker, and had them sign up on my behalf. They bought 100 event contracts for an average of $0.09 each, spending $9 in total, and we received our $10 reward. 

I like this bonus, and it’s one of the only actionable promos they have on deck. 

Beyond Kalshi’s welcome or referral bonus, there are a few ways to earn free cash on the site. 

Kalshi User Experience 

Kalshi simplifies futures trading for sports fans.

They present a clean, beginner-friendly UI that’s completely free from advertisements and pop-ups. Signing up, making my initial cash deposit, and buying my first event contract felt entirely effortless, thanks to guided instructions. 

The Kalshi sports betting mobile app does a great job of downsizing the entire experience on your cell phone. I enjoyed immediate loading speeds, watched real-time statistics, and kept an eye on trending topics all on the smaller screen. 

As a financial exchange site, Kalshi appears and functions differently from a traditional sportsbook. That said, I found actually entering event contracts to be pretty similar to placing bets. 

In my opinion, the simplified format is well-suited to total beginners who want an easy way to make sports bets and predictions. However, if you’re used to all the functionality of a sportsbook, you might be frustrated by the lack of certain types of bets, like parlays, for instance. 

Desktop 

I appreciate Kalshi’s all-white interface. It allows colors to stand out effectively from the screen, and the black typeface was easy to read on Chrome. Their interface is simple to a fault, with a few filters included to help sort through the different markets. 

I used the top menu rows to sort their markets by category and then by sport. 

Clicking “Sort/Filter” allowed me to sort event contracts based on popularity, volatility, recency, total volume, and liquidity.

However, not all of these filters were working during my Kalshi review. One filtering option called 50-50 is supposed to show markets where both sides are close to 50%, but nothing happened for me when I turned it on. 

Toggling the slider to display “Contract Price” enabled me to view the specific price for each event contract. 

Instead of seeing “Yes/No,” you’ll see the best price for a single “yes” contract and the best price for a single “no” contract. It may sound complex if you’re used to simply seeing moneyline odds, but I found it very easy to grasp the format and understand what was happening at a glance.

I appreciate the opportunity to be more involved in how other players utilise Kalshi, which doesn’t typically occur at traditional sportsbooks. 

You can check out the real-time leaderboards, where you can see the top dogs in terms of total profit and series volume by opening the top-right menu and toggling “Leaderboard.” 

Unlike the concept of leaderboards at traditional casinos and sportsbooks, Kalshi doesn’t offer prizes for top-ranked players. Instead, it’s a nice feature that provides a sense of the activity on the site. 

The “Ideas” tab hosts a social-media-style discussion forum, where users can comment on contracts and interact with each other.

You can borrow inspiration from the most successful traders by clicking their usernames to view their real-time trades, ideas, markets, and comments. Alternatively, clicking "Activity" gives you more of a bird’s eye view of everything happening on the site, and trades being completed right now.

The whole experience feels very much like participating in a marketplace, with the digital hustle and bustle of other Kalshi users all around you. 

Mobile App 

The Kalshi mobile app is available for both iOS and Android.

As a federally regulated financial exchange market, Kalshi has no problem adhering to the App Store and Google Play’s guidelines. I downloaded their iOS app to my iPhone 16, and my trading experience was seamless from the start. 

After signing in with my email and password, I was brought to Kalshi’s trending categories. They have maintained a consistent interface design between desktop and mobile, so I didn’t experience any issues transitioning between devices. 

Their logo still functions as a home button, and their categories are condensed into a scrollable horizontal list at the top of your screen. On mobile, I was able to view in-game markets from the bottom-right corner by clicking “Live.” 

Most navigation is accessed through the bottom-row menu. I was able to search for markets, fund my account, explore other users’ freshest ideas, or launch the main menu with one hand free.

My overall impression of using Kalshi is that it provides a clean and sleek experience, and the app plays a significant role in that. 

Other apps similar to Kalshi are daily fantasy ones. Have a look at the best DFS apps and sites.

Kalshi Features 

Kalshi doesn’t support traditional moneyline wagers and many other markets you’re used to from traditional sportsbooks. 

That said, I found it surprisingly easy to understand Kalshi’s event contracts, and ultimately, I ended up betting on many of the same sports and games that I usually would - albeit via Kalshi’s Yes/No prediction format. 

They also cover a lot more than just sports wagers, with numerous non-sports markets, live trades, and a public forum for ideas.

Kalshi Sports Markets

Kalshi’s basic sports markets resemble futures bets. During my Kalshi review, the first sports markets I saw were things like Pro Men's Basketball Champion? Champions League Winner? and Masters Tournament Winner?

For each of the potential teams or outcomes, you can choose either Yes or No. 

There were also markets for individual games, but I could only bet on the outcome. At a traditional sportsbook, I would be used to seeing hundreds of ways to bet on upcoming games, including spreads, props and plenty more. 

I can see this being frustrating for more experienced bettors who want to get granular with their predictions. For this reason, Kalshi does seem more suited to casual bettors.

Buying a contract is very similar to placing a bet on a sportsbook. After you click either "Yes" or "No" (or the corresponding value, if you have enabled the Contract Price button), a small window opens that resembles a bet slip. Type in your stake and confirm the trade.

During my Kalshi review, they were accepting action on the following sports:

• Basketball 

• Soccer 

• Golf 

• Tennis 

• Baseball

• Football

• Formula 1 

• Hockey 

• UFC 

• Esports

• Chess 

Live Betting 

Kalshi’s live betting section isn’t exactly like the live section at regular sportsbooks. It does show some events happening now, as well as upcoming events for the next few days. 

At the time of my review, I was able to access live contracts for golf and soccer.

They don’t offer streaming of any kind, but I saw my winning odds change based on real-time score updates every few minutes. 

If you're looking for traditional live betting, take a look at the best live betting sites.

I decided to place my first live wager on the Barcelona vs SL Benfica match-up, which wasn’t actually live but taking place a couple of days later. 

Each individual contract was priced at $0.93 or $0.08, respectively. Spending $10 got me 111 contracts, which promised more than 11x my original stake if Benfica overcame Barcelona. 

It all sounds kind of technical, but the truth is you don’t really need to pay attention to concepts like contracts. It’s easy to see how the bets work from just a glance. I liked the way Kalshi showed my prospective payout after I chose a stake - just like a bet slip on a regular sportsbook. 

Non-Sports Bets at Kalshi 

Kalshi is a financial exchange market first, and sports wagers are just a small part of what they have to offer. Beyond sports, they allow traders to wager against one another on various topics. 

Here are some of the categories on offer: 

• Politics

• Culture 

• Crypto 

• Climate

• Economics

• Mentions (during press interviews or speeches)

• Companies

• Financials

• Tech & Science

• Health

• World 

From betting on the weather and choosing the #1 song on the Billboard Top 200 to predicting the number of active measles cases this year and shining a light on Trump’s tariffs, Kalshi is a space for random ideas to compete. 

When you click into a trade, it shows you both the history of the action in graph format and a tab of suggested related markets. I found this especially helpful for exploring the non-sports markets since they are so wide-ranging. 

Public Forums & Ideas

Kalshi’s Ideas is a space on the site that lets you connect with other players. The interface resembles Twitter (X) closely, and you have an 800-character limit for each post. 

I had fun scrolling through people’s latest predictions, watching traders interact in comment threads, and putting my thumb on the pulse of Kalshi’s community.

I also found this space useful for asking questions about how certain features worked, with other players answering me in real-time. This was especially helpful since Kalshi doesn’t have live chat customer support (more on that later).

I also toggled over to Live Trader, which shows the same information as their “Activity” feed. While it’s nice to have real-time updates at my fingertips, they don’t need duplicate sections to show the same stream of live trades. 

There is also a Market Builder where you can create and offer action on your own markets.

Kalshi Deposits & Withdrawals 

Making deposits and withdrawals is easy at Kalshi, and the process feels similar to that of a regular sportsbook.

Beginners will have no trouble depositing and withdrawing money from their Kalshi account, and age verification is already built into their website. I didn’t have to submit a photo of my ID or proof of address before withdrawing funds. 

Kalshi accepts many of the same betting payment methods you’ll find at traditional sportsbooks, as well as cryptocurrency. Unlike most sportsbooks, they also charge varying fees on both deposits and withdrawals. 

See more on betting sites that accept crypto.

Let’s take a closer look: 

Kalshi Deposits

I could fund my account using Visa, Mastercard, Google Pay, instant bank transfer, wire transfer, and crypto on Kalshi’s desktop website. I downloaded their app to my iPhone 16 and found another option to use Apple Pay, but this method also comes with a 2% processing fee.

Here is how the process looked for me for a $10 deposit:

1. I clicked “Deposit Cash” from their homepage. On the next page, I clicked “Deposit to Kalshi” and selected “Debit Card.

2. I typed in the amount of cash I wanted to deposit, clicked “Add a Card” and entered my billing address. 

3. I was then prompted to enter my name, card number, expiry date, and CVV code.

4. Finally, I clicked “Pay $9.80 + $0.20 fee,” refreshed the page, and saw $9.80 in my account balance 30 seconds later. 

I’m not used to being charged to fund a sportsbook, so this is a downside of using Kalshi. 

You must deposit a minimum of $10 in cash, but I didn’t see a minimum for crypto traders. I saw options to send crypto funds through Ethereum, Optimism, Polygon, and Solana. 

The methods have variable maximum deposit limits:

• Debit Cards - $2,500 limit

• Apple Pay - $2,500 limit

• Instant bank transfer - $10,000 limit

• Crypto - $500,000 limit

Wire transfers have a $2,500 minimum but no maximum, making them the best choice for high rollers and crypto. 

It’s a good range of payment methods, in my opinion, catering to all kinds of users with different budgets. 

Kalshi Withdrawals

The withdrawal process is very similar to deposits, only in reverse. Click the “Withdraw from Kalshi” button, choose your method and follow the instructions. 

Cash withdrawals at Kalshi are processed via debit card or bank transfer. Crypto traders can withdraw via the same currency they deposited.

There is a $2 fee for all debit withdrawals, and crypto transfers are subject to third-party fees from ZeroHash.

Both debit card and crypto withdrawals are delivered in less than 30 minutes. ACH transfers via Plaid have no fees and no maximums, but they can take 3 - 4 days for processing and delivery. 

I chose a debit card withdrawal and found the process fast and smooth. I just typed in my details, confirmed the request and the money hit my account within ten minutes. 

I do admit that the $2 fee left a slightly bitter taste in my mouth, since it’s not something I’m used to experiencing when I bet using regular sportsbooks. 

Kalshi Payment Methods Comparison 

Here’s a comparison of how Kalshi’s payment methods compare to real money sportsbooks: 

Kalshi Customer Support 

Kalshi primarily relies on email support and its Help Center (FAQ), focusing heavily on its user community for peer-to-peer assistance.

Kalshi prioritizes community engagement over dedicated, real-time agent support. While the Discord community is highly valuable, the lack of live chat or phone support can make resolving complex issues frustrating and time-consuming.

Is Kalshi Legit? 

Kalshi is a legit financial exchange market regulated at the Federal level. Trading at Kalshi is not considered sports betting in the same way as betting on sites like BetMGM or FanDuel. 

Kalshi was regulated as a “Designated Contract Market” by the Commodity Futures Trading Commission (CFTC) in 2020, and they first opened shop in July 2021. In January 2025, they started hosting sports markets. 

Kalshi accepts secure payment methods like Visa, Mastercard, bank transfer, wire transfer and Apple Pay for deposits and withdrawals. Kalshi has also partnered with ZeroHash to monitor crypto transactions for tax, regulatory, and safety purposes. 

ZeroHash operates in more than 200 countries, has served five million end customers, supports more than sixty kinds of crypto and has settled more than $45 billion in total transaction volume. 

Beyond their commitment to security, Kalshi demonstrates a high degree of public transparency.

Kalshi is backed by high-profile investors like Charles Schwab, Henry Kravis and Y Combinator. Their LinkedIn has 14k followers, and their company employs between 51 - 200 people. 

How to Sign Up for Kalshi 

I registered with Kalshi in just five minutes, thanks to their step-by-step instructions, which made the process easy to complete. Here’s how I made a new account and started browsing markets: 

1. Create a new account: Click “Sign Up” at the top-right corner of Kalshi’s website. You’ll notice options to register using Google, your Apple ID, or an email address. I chose to enter my email and create a new password before clicking “Continue” to proceed. Your Kalshi referral code WSN will be automatically applied.

2. Verify your email: Open your inbox and look for a new message from Kalshi. If you don’t see it appear momentarily, check your spam or junk folder. Once you find their message, open it and copy the code. Paste your six-digit code on their website and tap “Continue.” 

3. Verify your phone: On the next screen, enter your date of birth and type your cell phone number when prompted. You’ll receive a verification code through SMS. Enter your SMS code on their website and wait for the page to refresh automatically. 

4. Verify your identity: Enter your first name, last name, and residential address on the next page. Finally, enter your nine-digit Social Security Number and click “Submit” to register. 

I was redirected to Kalshi’s homepage as soon as I finished signing up and verifying my details. 

Once you’re ready to deposit money, click “Deposit Cash” and follow their instructions.

Kalshi Responsible Gambling 

Kalshi does not offer responsible gambling services that I am used to seeing at traditional sportsbooks.

The FAQ has a Responsible Risk Management section, which offers three tools for “traders” on Kalshi. Trading Break temporarily restricts account trading activities for one day or longer, Voluntary Opt-Out allows users to request exclusion from trading activities, and the Personalized Funding Cap lets you set maximum monthly deposit limits. However, all of these rely on the individual to limit their activity, and doesn’t restrict access to Kalshi events on external Futures Commission Merchants.

They’ve dropped the ball in this department. According to Kalshi’s Help Center, it’s possible to de-activate your account using their provided links, once you have cashed out all active contracts and withdrawn all funds. However, re-activating your account is as simple as logging in with your credentials. 

Because they operate under federal exchange laws, Kalshi is not legally allowed to delete your account. Worst of all, there’s no wait time between deactivation and reactivation. Someone who wants to avoid the platform can simply log in if they change their mind in a few hours.

Kalshi also doesn’t link to resources for problem gamblers.

WSN doesn’t agree with this approach, and we take the safety of every user seriously. Our Responsible Gambling Center shows readers how to stay in control of the action. 

You can read “Do You Have a Gambling Problem?” or take our linked Gambling Self-Assessment Quiz if you or someone you know is struggling to moderate. If you need more support, we provide links to responsible gambling tools and resources for casino players and sports bettors in all 50 states. 

Kalshi Final Verdict 

Kalshi is best suited for beginners and casual players due to its unique, simplified Yes/No event contract format, which eliminates the complexity of traditional betting terms like point spreads, moneylines, and parlays.

Bottom line? Kalshi is an interesting, highly accessible platform for those seeking an extremely simple way to start speculating on real-world events (including sports outcomes). However, it is not a substitute for a full-featured sportsbook for serious or experienced bettors.

How We Rate Sportsbooks 

We use the same rating process for every sportsbook we review to provide an overview of each platform’s biggest strengths and weaknesses. All in all, we spend at least seven days playing on every site we review. 

Our team spends ten hours diving into five important areas, allocating two hours for each of the following benchmarks: 

1. User Experience: We register new accounts and test out all the features of the sportsbook. If there is a mobile app available, we download it. We appreciate well-designed software that makes the betting experience easy for beginners but also satisfying for more experienced bettors. 

2. Features: We dive into the betting options, placing bets on dozens of sports and comparing the markets to competitors. We pay special attention to unique features, like live streaming or pick’em sports games. We compare the odds to other sportsbooks leading sportsbooks too.
