What Is Kalshi?

Kalshi is a CFTC-regulated prediction market where users trade contracts on real-world events instead of betting against a sportsbook.

Markets cover sports, politics, economics, weather, entertainment, cryptocurrency, and other topics, with every contract settling at either $1 or $0 depending on the outcome.

Kalshi is one of the few federally regulated prediction market apps available in the United States.

Since sportsbooks can’t offer political markets in the US, Kalshi fills that gap.

Political Markets
Kalshi offers event contracts related to elections, government actions and other political events. Contract availability and trading eligibility can vary by jurisdiction, market, and CFTC certification.

How Do Kalshi Event Contracts Work?

Kalshi event contracts are yes/no shares priced between $0.01 and $0.99 that pay $1 if the outcome occurs and $0 if it doesn’t. The price reflects the market’s implied probability — a $0.60 contract equals a 60% chance.

For example:

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.

Transparent Fee Structure

As a CFTC-regulated exchange, Kalshi uses a transparent transaction fee model instead. Kalshi charges no settlement fees and free ACH deposits; every withdrawal costs a flat $2.00.

Prediction Markets Available 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:

Top Non-Sports Prediction Markets on Kalshi Today

Kalshi’s contract prices change as traders react to new information. I’d check the latest quotes, trading volume and settlement rules before opening a position, especially on markets with several possible outcomes.

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 federally regulated by the Commodity Futures Trading Commission, which requires it to follow rules protecting traders and market integrity.

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 (October 2026)

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.

If you want to check the details for a specific state, see our full guides on Kalshi in California, trading on Kalshi in Texas, and Kalshi’s Florida availability.

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

State availability last reviewed October 19, 2026. Prediction market litigation is moving quickly and several cases are on appeal — Kalshi verifies your location at sign-up and shows the markets currently open to you, which is the authoritative answer for your state.

Kalshi Promo Code vs. Competitor Bonuses

While Kalshi offers a top-tier sign-up bonus, competitors like Polymarket, FanDuel Predicts, Novig, DraftKings Predictions and ProphetX also run new-user promos.

Use the comparison table below to evaluate current welcome offers, promo codes, and key terms side-by-side.

Key Takeaway

The Kalshi welcome bonus is one of the simplest offers available among regulated prediction markets. Because qualifying trades only require $25 in total volume, new users can spread their trades across several markets while learning how the exchange works.

Let’s Take a Closer Look: Kalshi vs. Polymarket

If you’re comparing prediction market apps, Kalshi and Polymarket are usually the first two platforms that come up. Both are now CFTC-regulated in the United States, both offer sports and political markets, and both allow users to trade event contracts rather than place traditional bets.

That said, the experience on each platform is a little different.

Polymarket has become one of the most popular prediction market apps thanks to its mobile-first design, competitive fee structure, and Deposit $10, Get a $25 Trading Bonus! offer. The platform offers markets across sports, politics, economics, culture, technology, and weather.

Kalshi, meanwhile, offers a larger selection of markets, deeper coverage across categories, and a superior desktop experience.

Kalshi vs. Polymarket: Which One Should You Choose?

Kalshi is the strongest starting point. You get the widest range of contracts, more ways to fund your account, and the flexibility to trade on desktop or mobile — plus the Trade $25, Get $55! welcome offer with promo code GRINDERS55.

Polymarket is still worth a look if you trade mainly from your phone and want a stripped-down app for the biggest markets.

Many traders, myself included, keep accounts on both Kalshi and Polymarket, and use whichever has the market, price, or bonus they want at the time.

If you’re still unsure on which platform is the better fit, you can check our Kalshi vs. Polymarket breakdown for a deeper look at the bonuses, fees, market selection, and overall experience.

💡 How I’d Use the Kalshi Welcome Bonus (NFL, CFB)

If I were using the “Trade $25, Get $55!” Kalshi offer for the first time, I’d spread my qualifying trades across a few markets instead of putting the entire $25 on one outcome. That way, I could see how prices behave in both short-term games and longer-running contracts.

For example:

1. Start tonight with Monday Night Football. Commanders vs. 49ers kicks off at 8:15 p.m. ET on ABC/ESPN, closing out NFL Week 6 — a good first market to check contract prices and trading volume before you commit much.
2. Add a baseball trade. ALCS Game 6, Guardians vs. Rays, runs at the same 8 p.m. ET window on TBS, so you can spread a little volume across sports and watch how a win-probability market moves in real time.
3. Look ahead to tomorrow’s NBA Opening Night. The season tips off with a triple-header on NBC — Celtics vs. Pistons (3 p.m. ET), 76ers vs. Knicks (7 p.m. ET), and Thunder vs. Spurs (9:30 p.m. ET) — plus a possible ALCS Game 7 if the series goes that far. You could also hold part of your qualifying volume for a longer-dated market, like the 2027 NFL champion.

The best part is you don’t need to wait for your trades to settle to meet the qualifying volume requirement. Once you’ve completed $25 in eligible trades, Kalshi credits the bonus automatically, and you’ll have seven days to use it.

Kalshi Market Movement Example

Daily game markets move more than most people expect. In the August 8 Yankees-Braves market, New York opened at 55¢ and had slipped to 50¢ before a Spencer Jones triple scored a run and pushed it to 66¢ — a 16-point move on one play.

Those contracts settled at $1 after the Yankees won 5-4. The August 10 Red Sox–Blue Jays market went the other way: Boston opened at 58¢ and was still sitting at 59¢ hours later.

Both are worth watching while you clear the $25, because one shows how fast a single play reprices a market and the other shows how many games simply don’t move.

A few tips:

• Look past the headline market. Division and conference winners, season win totals, and daily games give you far more chances to trade than championship odds alone.
• Don’t chase yesterday’s results. A blowout or upset moves prices fast, but those overreactions often open up value elsewhere.

Ongoing Promos at Kalshi (October 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 & Earn a $55 Bonus

If you enjoy using Kalshi, the Refer-a-Friend program is an easy way to pick up some extra bonus funds.

Invite a friend to join, and once they complete the qualifying requirements, you and your friend each become eligible for your own $55 bonus credit. The two rewards are independent — your amount doesn’t depend on theirs, and vice versa.

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?

After your first trade and identity verification, open the “invite friends” tab in your account, copy your unique referral link, and send it to whoever you want to invite.

You can also share the Kalshi code GRINDERS55 with your friends so they can claim the same Trade $25, Get $55! welcome offer after their first $25 in trades. Just note they can use one or the other — a referral link or the promo code, not both.

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

Trading Perpetual Futures on Kalshi

Kalshi also offers additional trading products, including perpetual futures. These products differ from event contracts and involve different risks and mechanics.

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

Is There a Kalshi Perpetuals Invite Code?

No, you don’t need an invite code. You can use our Kalshi promo code GRINDERS55 to register and get both the welcome offer and access to Perpetuals.

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.

Know the Kalshi Tabs

Getting the hang of the app is easy, so here’s what each tab covers.

Trading “High Volume” vs. “Top Movers”

Two filters matter most when you’re clearing the GRINDERS55 bonus: High Volume and Top Movers.

Here is how to use them to your advantage:

• High Volume Markets: The most actively traded contracts on Kalshi. Higher activity means tighter spreads and easier order execution, which makes them a practical starting point.
• Top Movers: The markets with the biggest recent price changes — the fastest way to see where traders are reacting to news or in-game events. The August 9 Padres–Astros market showed how sharp that can get: San Diego was trading at 44¢ before a three-run Fernando Tatis Jr. home run moved it to 76¢, a 32-point swing on a single at-bat. San Diego won 7-2 and those contracts settled at $1.

⚠️ Trader Tip: High volume tells you a market is liquid, not that its price is correct. Check your own read against it before you trade.

Integrations & Partnerships (MLB, Robinhood, CNN, PrizePicks Predicts)

Kalshi’s growing presence has helped bring prediction markets into the mainstream through partnerships with major financial, media, and gaming companies:

• MLB Partnerships: Kalshi has expanded its sports presence through exclusive, multi-year partnerships with five MLB clubs: the Los Angeles Dodgers, Atlanta Braves, Boston Red Sox, San Diego Padres, and San Francisco Giants. The deals include in-stadium signage along with social, digital, radio, and fan activations, giving Kalshi a bigger presence around Major League Baseball.
• Robinhood Integration: Following a successful pilot during March Madness 2025, Robinhood now offers a variety of Kalshi’s event contracts (sports, politics, and economics) directly within the Robinhood app, allowing users to trade prediction markets using their existing brokerage accounts.
• CNN Partnership: CNN designated Kalshi as its official prediction markets partner. Kalshi’s real-time probability data is integrated into CNN’s newsroom coverage via an on-air ticker and utilized by data analysts to forecast political and macro events.
• PrizePicks Predict Partnership: Kalshi has also expanded its reach through partnerships with gaming operators such as PrizePicks. Through PrizePicks Predict, users can access prediction markets powered by Kalshi technology, helping introduce event-based trading to an even broader audience.

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 under 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.
