Kalshi Promo Code GRINDERS for June 2026

Does Kalshi Have a Welcome Bonus?

Yes! The Kalshi welcome bonus for new users is Trade $10, Get $10!

What I personally like about this offer is that it doesn’t come with those annoying, complicated “rollover” rules you usually see at big sportsbooks.

1. Register with the Kalshi promo code GRINDERS

2. Deposit $1+

3. And trade $10 in total on event contracts to get the $10 bonus.

Simple. Your trades don’t even have to win. As long as you’ve traded the required $10, you’ll receive the bonus.

Once the bonus arrives, you’ll have 30 days to use it on eligible Kalshi markets.

Sign Up with Kalshi Promo Code GRINDERS

1. Open the Kalshi app.

2. Click on “Sign Up”.

3. Register with an email or Google/Apple account.

4. Type in the Kalshi promo code GRINDERS.

5. Enter your legal name, DOB, phone number, physical address, and Social Security number.

6. Upload a photo of your driver’s license/passport and a selfie. Unverified users can browse live order books, but cannot trade.

7. Go to the hamburger menu icon and select “Add funds”. Kalshi accepts debit cards, ACH bank transfers (zero fees), wire transfers, and crypto (USDC).

Note: If you want to use crypto, purchase USDC on a wallet like Coinbase and ensure you select the matching asset network (e.g., Base) to avoid lost funds.

8. Place a total of $10 in trade volume to trigger your bonus funds.

The verification process at Kalshi is similar to claiming the Underdog promo code, so make sure you grab that bonus, too.

Kalshi Promo Code vs. Competitor Bonuses

If you’re shopping around for the best prediction market bonus, Kalshi is definitely worth considering.

That said, Kalshi isn’t the only prediction market app offering a welcome bonus. Platforms like Polymarket, FanDuel Predicts, Novig, and ProphetX have their own promos for new users.

To help you compare your options, I’ve put together the table below, which breaks down the current offers, promo codes, and key details for some of the most popular prediction market platforms available today.

Trade $10, Get $10 on the World Cup and U.S. Open

If you’re looking for the most active markets on Kalshi right now, the World Cup matches and U.S. Open tournament are great spots to put your first $10 trade.

The welcome offer only requires $10 in total trades, so you can spread your positions across multiple markets to get the bonus.

⚽ 2026 World Cup Markets

The World Cup futures market could see another round of movement over the next few days.

Mexico became the first nation to qualify for the Round of 32 after defeating South Korea 1-0, while Canada’s 6-0 win over Qatar and Switzerland’s 4-1 victory over Bosnia-Herzegovina helped clarify the picture in Group B.

The United States faces Australia on Friday, June 19, Germany takes on Ivory Coast on Saturday, June 20, and Spain returns to action against Saudi Arabia on Sunday, June 21.

A few strong performances could change how traders view the tournament. That’s especially true as teams move closer to securing a place in the knockout stage and the World Cup Winner market begins to take shape.

Some of the most popular World Cup markets on Kalshi include:

• World Cup Winner
• Group Winners
• Teams to Advance
• Match Winners
• Golden Boot Winner

If you’re new to trading soccer markets, here are a few simple tips:

• Look Beyond the Tournament Winner: Markets like “To Advance” and “Group Winner” often provide more opportunities than simply picking the eventual champion.
• Don’t Overreact to One Match: Early World Cup results can create sharp price swings. Sometimes the best opportunities appear after the market reacts too aggressively.
• Follow Team News Closely: Injuries, suspensions, and lineup changes can have a big impact during a short tournament.
• Stay Flexible: One advantage of Kalshi is that you can adjust your position as the tournament develops instead of being locked into a single prediction.

With World Cup matches taking place almost every day, expect these markets to become some of the most active contracts on the platform throughout the summer.

Volume and Liquidity

One reason I like World Cup markets for newer traders is the volume.

The biggest international matches attract thousands of participants, which generally means tighter spreads and a smoother trading experience.

In simple terms, it’s usually easier to enter and exit positions when more people are active in the market.

How I’d Use the Trade $10, Get $10 Bonus

If you’re working through the welcome offer, I’d focus on the biggest World Cup markets first.

Right now, World Cup Winner, Golden Boot Winner, and the daily match markets are attracting a lot of attention. They’re easy to follow, highly liquid, and a great way to learn how prices move.

My advice? Spread your first $10 in trades across a few different World Cup markets. You’ll unlock the bonus while getting a feel for how Kalshi reacts to goals, results, and breaking tournament news.

⛳ U.S. Open Markets

Major championships tend to attract some of the most active golf markets of the year, especially once players start making moves up and down the leaderboard. A strong opening round or a difficult stretch of holes can create meaningful price swings throughout the tournament.

If you’re following the U.S. Open this week, keep an eye on outright winner markets, Top 10 finishes, and make-the-cut positions.

Scottie Scheffler entered the U.S. Open as the favorite, but a rough opening round has created opportunities elsewhere on the board. Golfers like Tommy Fleetwood, Cam Young, Si Woo Kim, and Chris Gotterup have attracted attention from bettors looking beyond the tournament favorite.

Just like the World Cup, the key is staying flexible. One hot round can dramatically change a player’s chances, creating opportunities for traders who are paying attention throughout the tournament.

Ongoing Promos at Kalshi (June 2026)

The welcome bonus isn’t the only way to get extra value from Kalshi. The platform runs regular promos to keep users engaged, including referral rewards and occasional offers tied to major sporting events and other high-interest markets.

Refer-a-Friend & Get a $25 Bonus

If you enjoy using Kalshi, the Refer-a-Friend program is an easy way to pick up some extra bonus funds. When you invite a friend to join the platform and they complete the qualifying requirements, both of you can earn a $25 bonus.

It’s a nice perk if you have friends who are curious about prediction markets and want to try trading alongside you.

How can I refer a friend on Kalshi?

The process is simple—after your first trade and identity verification, you need to find the “invite friends” tab in your account. Copy the unique referral link and send it to your friends for sign up.

You can also share the Kalshi promo code GRINDERS with your friends so they earn the $10 Kalshi bonus after their first $10 in trades.

🚨​ The current Kalshi referral code is not the same code you’ll receive when referring a friend.

What Is Kalshi?

Kalshi is a regulated prediction market platform that lets you trade on the outcomes of real-world events.

While many users come to Kalshi for the sports markets, you can also trade on politics, economics, weather, crypto, and pop culture topics, making it one of the best prediction market apps available today.

Unlike a traditional sportsbook or daily fantasy sports apps, Kalshi works as an exchange where users trade with each other rather than against the house. Markets are built around simple questions, such as “Will Team USA advance?” or “Will Bitcoin reach a certain price this month?”

Kalshi is regulated by the Commodity Futures Trading Commission (CFTC), making it one of the few federally regulated prediction market platforms available in the United States.

Seeing as political betting in the US is not available at sportsbooks, Kalshi is definitely the next best thing.

How Do Kalshi Event Contracts Work?

One of the reasons Kalshi has become so popular is that the markets are surprisingly easy to understand.

Every market starts with a simple question that can be answered with either “Yes” or “No.”

For example:

If you think the answer is “Yes,” you can buy Yes contracts. If you think the answer is “No,” you can buy No contracts.

Each contract is priced between $0 and $1, and that price reflects what the market thinks the chances are of the event happening. For example, if a “Yes” contract is trading at $0.60, the market is essentially saying there’s about a 60% chance of that outcome occurring.

When the event is resolved, winning contracts pay out $1, and losing contracts are worth $0.

One thing I like about Kalshi is that you don’t have to hold your position until the event ends. You can sell your contracts early, take profits, or limit potential losses before the market officially settles.

That makes the experience a bit different from a traditional sportsbook. You’re not making a pick and waiting for the final result, you’re participating in a market where prices constantly adjust as new information comes in.

Those who would prefer actual sports betting might claim the Caesars Sportsbook promo code. If you’re looking for a social sports trading platform rather than one that uses real money, check out the Manifold Markets promo code.

Transparent Fee Structure

Sportsbooks hide their commission (the “vig”) inside the odds, which usually acts as a baked-in 4.7% tax on your money. As a CFTC-regulated exchange, Kalshi uses a transparent transaction fee model instead.

What Can You Trade on Kalshi?

While many users first discover Kalshi through sports markets, you can trade on politics, economics, weather, pop culture, crypto, and other real-world events.

These are some of the most popular categories available on Kalshi:

We expect the Coinbase referral code to grant you access to markets similar to Kalshi’s!

Who Is Kalshi Best For?

Kalshi is ideal for users interested in trading real-world event outcomes instead of placing traditional bets.

It’s popular with traders and sports fans, but also attracts analysts and political followers who track markets tied to economic data, performance trends, and elections. During the U.S. presidential race, for example, Kalshi markets briefly priced Donald Trump as the favorite.

Is Kalshi Legit?

Yes, Kalshi is 100% legit.

The platform is regulated by the Commodity Futures Trading Commission (CFTC), which means it operates under federal oversight and follows strict rules to protect users and ensure markets are fair.

Unlike competitors like Smarkets, Kalshi is legal in most U.S. states and offers a regulated alternative to traditional sports betting apps, allowing users to trade on real-world event outcomes through a federally approved platform.

Kalshi Legal States (June 2026)

Is Kalshi legal in California? Yes.

Is Kalshi legal in Texas? Yes.

Is Kalshi legal in Forida? Yes.

One thing many users like about Kalshi is that it’s available in states where traditional sportsbooks aren’t. Thanks to its federal regulation, people in places like California and Texas can access the platform and trade event contracts.

That said, some sports-related markets may still be unavailable in certain states as regulations around prediction markets continue to evolve.

Trading Perpetual Futures on Kalshi

What Are Perpetual Futures?

Perpetual Futures are a newer product on Kalshi that lets you trade the price movement of assets like Bitcoin.

Unlike prediction markets, there’s no expiration date. You’re simply taking a position on whether you think the price will go up or down.

How Do They Work?

If you think an asset will rise in value, you can buy. If you think it will fall, you can sell.

Your position stays open until you decide to close it, and Kalshi also offers leverage for traders looking for additional exposure.

If you’re new to Kalshi, I’d still recommend starting with prediction markets. Perpetual Futures are designed for more experienced traders who want to follow asset prices rather than event outcomes.

Kalshi App Features & Navigation

The Kalshi mobile app (iOS and Android) focuses on making an open order book legible for casual retail traders. Rather than digging through overwhelming financial charts, the UI is built for rapid filtering.

• Market Discovery Menus: The sidebar filters active markets by Trending (highest current attention), Top Movers (largest recent price swings), New (recently listed), and Highest Volume (best liquidity).
• The “Ideas” Tab: A social feed where users share strategies, post live trades, and discuss market angles.
• Market Builder: If you spot a gap in the order book, you can propose a new market. If the idea gains enough community traction, Kalshi will list it.
• Portfolio Tracker: A real-time tracker displaying your available cash balance alongside the fluctuating live value of your open positions.

Trading “High Volume” vs. “Top Movers”

As a data-driven trader, finding the right market is half the battle. Just like filtering a player pool in a DFS optimizer to find the best value plays, Kalshi gives you built-in tools to sort the board.

Two of the most powerful filters for clearing your GRINDERS bonus and building your bankroll are the High Volume and Top Movers tabs.

Here is how to use them to your advantage:

• High Volume Markets: These are the most actively traded markets on Kalshi. For new users, they’re often a great place to start because higher trading activity usually means smoother pricing and easier order execution.
• Top Movers: This section highlights markets seeing the biggest price changes. It’s a quick way to spot where traders are reacting to breaking news, major sports events, political developments, or other stories that are moving markets in real time.

⚠️ Trader Tip: Just because a market has high volume doesn’t mean it’s “right” or that the current price is perfectly accurate.

All trading comes with inherent risks. Just like finalizing a DFS lineup, you should always step back, trust your own projections, and analyze all the underlying variables before officially placing your trade.

Deposits and Withdrawals at Kalshi

As a federally regulated prediction market, Kalshi has secure deposits and withdrawals.

Here’s a look at how you can deposit funds so you can make your first $10 in trades and qualify for the welcome bonus:

Remember, you must verify your account before depositing and trading at Kalshi.

You can sell early at any time, helping you potentially boost your withdrawals at Kalshi. AND, you can earn variable 3.25% APY on your cash and positions.

Crypto.com is another exchange platform that relies on cryptocurrency—check out the Crypto.com promo code review for more details.

Kalshi Customer Service

You only have two options for contacting the support team at Kalshi—email support@kalshi.com or join the Discord server.

Even though there’s no live chat or phone number to call, the customer service reps are pretty helpful and should get back to you within a reasonable timeframe.

See how the customer service at Kalshi compares to that at FanDuel’s prediction markets app.

Responsible Trading & Risk Management on Kalshi

As a regulated financial exchange, Kalshi prioritizes user protection over endless volume. Instead of generic advice, Kalshi provides built-in, account-level controls to help you manage your funds and exposure.

You can access all of these responsible trading tools directly in the app or on the web (Settings > Responsible Risk Management):

• Monthly Deposit Limits: Set a hard cap on how much cash you can transfer into your Kalshi account.
• Trading Breaks: Enforce a temporary “cool-off” period. If feel you’re chasing losses, you can lock yourself out of making new trades for a short duration.
• Self-Exclusion: For long-term control, you can fully exclude yourself from the platform for a specified period.
• Confidential Support: Kalshi has an official partnership with Birches Health to provide confidential, professional guidance for healthy trading habits and financial decision-making.

🚨​ Important: Never trade with money you cannot afford to lose. While you can sell your shares early to mitigate losses, a wrong prediction can result in a total loss of the invested capital.
