The Kalshi promo code WSN gives new users a $10 sign-up bonus when they trade 100 event contracts.
In 2020, Kalshi became the first federally-regulated prediction market in the US under approval from the Commodity Futures Trading Commission (CFTC). New users in every state can claim the Kalshi bonus code to trade event contracts on sports, politics, culture, economics, and more.
Use the Kalshi referral code WSN when signing up to claim a $10 bonus when you trade 100 contracts. Kalshi is a prediction market and doesn’t facilitate betting, unlike sportsbooks, which tend to offer “bonus bets” as a deposit match or first bet insurance. Instead, Kalshi offers promotions including volume incentives, liquidity incentives, fee reductions for trading contracts, or trading credits like the Kalshi welcome offer.
Here’s a breakdown of the Kalshi welcome offer for new customers:

Claim Your Kalshi Referral Code

Claiming the Kalshi bonus code is straightforward: new users just need to enter the promo referral WSN during registration. You’ll have to complete identity verification when you sign up, similar to registering with an online casino or sportsbook. As a CFTC-regulated trading platform, Kalshi has slightly stricter verification checks, more akin to a brokerage account or financial product.
Follow my step-by-step guide to make sure you claim the Kalshi promo code correctly:
Follow our secure link to Kalshi. Sign up with your existing Google or Apple credentials, or click “Continue with Email” to register manually.
Enter your email address and click “Continue”.
Set a secure password following the instructions and click “Continue”.
Open the verification email from Kalshi and copy the code. Input the verification code and, once again, click “Continue”.
Enter your mobile phone number and check that the promo code has automatically applied. If not, enter the Kalshi promo code WSN on this page before clicking “Continue”.
Enter the verification code sent to your mobile and click “Continue”.
Verify your identity by filling out your full name, address, and Social Security Number. Click “Submit” to complete registration.
Click the green “Deposit cash” button in the header to open the cashier. If further verification is required before depositing, you’ll be redirected to complete this when you click your chosen payment method.
Select your payment method and fill out the details and amount as directed. Once the transaction is complete and funds are cleared in your account, select your first market and begin trading!
I always read the T&Cs closely before signing up to a new platform, and prediction markets are no different. Here are the key T&Cs I spotted for the Kalshi promo code and the platform overall:
Minimum Deposit: Kalshi has a low minimum deposit of $5, but you’ll need to deposit and trade 100 contracts to qualify for the bonus.
Trading Requirements: The minimum trading requirement for Kalshi bonus is 100 contracts.
Withdrawal Restrictions: Kalshi bonus credits are designed for trading and cannot be withdrawn directly. Profits from successful trades made with bonus credits can be withdrawn after a specified holding period, depending on your original deposit method.
Verification: Your account must be fully verified through KYC checks to receive the bonus, including verifying your age.
Location: Kalshi is regulated at a federal level by the CFTC and is legal in all 50 states. Residents in Massachusetts may find access restricted due to a preliminary injunction granted in January 2026, but Kalshi is not currently legally banned in any US state.
Every prediction market offers a different user experience and bonuses, so it helps to compare the platforms side-by-side. Here’s how some of the best prediction platforms stack up next to the Kalshi referral code for new users:

I asked our team of experts for their take on Kalshi:
Feedback from real Kalshi traders is mixed, with different opinions on the same factors. Many reviewers praised Kalshi’s customer service, but other reviewers were unable to get a satisfactory response. Transactions were speedy for some users, while others experienced delays and complained about fees.
I spotted a pattern of one-star reviews that seemed to be confused about the contract pricing model and comparing Kalshi’s payout structure to sportsbook odds. However, the trading process and prices are rated highly by others. Check out these real-user Kalshi reviews:
One user, G, rated Kalshi five out of five stars: “I deposited money and placed a few trades. My money was back in my bank within seconds of my withdrawal request. I'm not sure if it's because I have used Stripe (their debit card payment provider) for a long time and this verified me, but I was really impressed that Kalshi was the fastest withdrawal I have received.”
Dboogieb83 gave the Kalshi app for iOS five stars: “I find myself watching things I normally wouldn’t just to see if they would say a simple word because of [events contracts I discovered on] this app. It’s genuinely fun and low-key, I’m a little more caught up on current events.”
Brad gave Kalshi’s customer support five stars, saying: “The customer support team is incredibly helpful with any and all issues. They go out of their way to help resolve the problem.” Unfortunately, not everyone shared Brad’s experience.
Gow says: “Customer service messages say they will respond in 30 mins but haven’t responded in 4 days.”
If you’re used to wagering at online sportsbooks, you might be wondering how prediction markets work and what makes them different from sportsbooks. Prediction market platforms like Kalshi offer derivative contracts on the outcome of real-world events, including sports, which users buy and sell.
Each event on Kalshi is presented as a binary outcome with Yes or No contracts. For sporting events, this Yes/No format applies to outcomes like the match winner or overall game result, as well as more niche events that bear similarities to sportsbook selections: points totals, points spread, futures, and props.
Contract pricing differs from traditional betting and sportsbook odds. Prediction market binary outcomes are priced between 0 and 100 cents, with a higher purchase price indicating higher market confidence in the outcome. The purchase price can go up or down before the event settles, and correct contracts have a fixed payout of $1 per contract. If you purchase a “Yes” contract on “Will Seattle win the 2026 Pro Football Championship?” at 68¢ and they win, you’ll earn $1, which is 32¢ profit.
💡Conversion tip: Contract purchase price indicates implied probability of an outcome based on public sentiment of Kalshi traders. Here’s how this compares to sporting odds format:
Buying at 50¢: +100 odds equivalent
Buying at 75¢: -300 odds equivalent
Buying at 25¢: +300 odds equivalent
Kalshi facilitates peer-to-peer trading: users trade contracts with other customers, not against the “house.” Every trade is matched against another user trading with the opposite outcome. There are Maker trades (the user chooses the side, price, and number of contracts) and Taker trades (users view available offers and choose trades to match with).
The dynamic structure of contract pricing reflects public sentiment as market-assigned probability, without the in-built “house edge” of sportsbook pricing. Instead, Kalshi’s revenue comes from set trading fees and isn’t affected by the outcome of each trade. Simply put, Kalshi doesn’t win when traders lose.
Early Exit tip: If public sentiment changes, contract prices change. This means users can exit their position at a favorable market price before the event concludes, unlike sports betting where the wager is locked in. If you buy a contract at a low price and the price increases, you have the option of selling high rather than waiting for the final result. If your contract outcome decreases in price, you can exit the position and sell early (if another trader matches) to minimize potential losses.
You’ll need to fund your account to start trading on Kalshi. As Kalshi is a regulated financial exchange, funding your account works more like a brokerage account than depositing at a sportsbook.
Kalshi has a low $5 minimum deposit amount, but I recommend starting with at least $10 to cover your first trade, or $100 to simplify meeting the Kalshi referral code minimum trade requirement.
ACH Bank Transfers are the gold standard for funding your trading account. This method of payment connects directly to your bank for a secure transfer of funds in one to three business days. There are no fees for ACH payments on Kalshi, but debit deposits carry a 2% fee. While Kalshi doesn’t charge fees on wire transfers and crypto payments, the payment provider or third-party processor will set its own fees.
Important Funding Rule: Kalshi is a federally regulated exchange, meaning it does not accept credit cards. We strongly recommend linking your bank account (ACH) for your first deposit. It is fee-free and ensures you get 100% of your money into the market. Debit cards can be faster but incur a 2% processing fee, and debit withdrawals carry a $2 fee.
