Kalshi 2025 promo code POST: Earn a $10 bonus

Perhaps no trading platform is poised to make a bigger splash in 2025 than Kalshi.

The first CFTC-regulated exchange dedicated to trading on the outcome of future real-world events, Kalshi is taking things off the field and into the streets by offering punters the opportunity to trade on a wide range of topics like political elections, the Papal Conclave and the Nobel Peace Prize. 

Kalshi says it has developed a new asset class called “event contracts,” where users can buy “Yes or No positions” with respect to whether an event will happen or not.

This will allow folks to back their opinions on certain real-life events with actual money.

What to use the Kalshi promo code on

The most important business proposition at Kalshi is that you can wager on just about anything, and with election season in full swing, you can probably guess what the most popular markets are on Kalshi are:

As of writing, over $41 million has been wagered on the outcome of November’s mayoral election in New York City between Zohran Mamdani and Andrew Cuomo. Currently, the money is backing up Mamdani in a big way. Based on the handle, Mamdani boasts a 93 percent chance of winning the bid, while Cuomo is sitting at seven percent.

There are also markets up for the 2028 Presidential Election, with JD Vance (31 percent) and Gavin Newsome (23 percent) leading the way.

Another local election getting some action is the New Jersey gubernatorial election between Democrat Mikie Sherrill and Republican Jack Ciattarelli. This market is not as lopsided at the race for Mayor of New York City, but the punters on Kalshi have established a clear favorite.

The choices offered in this race are Democratic Party (Sherrill) or Republican Party (Ciattarelli), and it’s Sherrill that is the clear frontrunner at 80 percent.

Kalshi is also offering markets on Bitcoin, the Government Shutdown, and the Rotten Tomatoes score for the Bruce Springsteen biopic, Deliver Me from Nowhere.

There is also a market available for predicting whether or not President Trump will buy any bits of Greenland.

Of course, you can also use Kalshi to make predictions on sporting events including the World Series, NFL, and much more.

You can learn all about Kalshi, how it works, and more below.

All you have to do is sign up, enter the promo code POST, verify your account, and complete at least $100 in trades.

What makes Kalshi different from sportsbooks?

Kalshi is very different from sportsbooks and other trading platforms.

Instead of betting on the outcome of a game or a prop, users are trading on the outcome of real events in the world, like political elections, award ceremonies or even inflation rates.

Prices shift on demand, meaning the more money that comes in on a prediction, the shorter the price will get.

For example, if money pours in on Stephen A. Smith to become the next president, the price on “Yes” will increase, while the price on “No” will decrease.

Another important note about Kalshi is that it allows traders to exit positions early, like a stock exchange. In other words, you can buy into a position, then sell it off later if/when the market moves.

Does Kalshi list the odds of an event?

No, Kalshi doesn’t list odds like traditional sportsbooks. Instead, Kalshi uses percentage-based pricing.

It may take some getting used to, but seasoned bettors will know how to convert these percentages to odds by using implied probability.

Can you trade on sporting events at Kalshi?

Although Kalshi originally started with trading on real-world events, they made their way into sports, though it differs from traditional sports betting

Due to regulatory restrictions, Kalshi only allows its users to make “futures” trades on long-term outcomes like:

• Who will win the Super Bowl?
• Who will be a team’s next head coach?
• Who will win the 2026 World Cup?

Here is a current example available on the Kalshi app:

An example of how Kalshi lists probability

Team	Yes/No Probability
Philadelphia	12%
Baltimore	12%
Buffalo	12%
Kansas City	11%

How do trades settle on Kalshi?

Here’s how a trade settles on Kalshi:

• A contract costs between $0.01 and $0.99.
• Winning contracts settle at $1.

For example, let’s say France is trading at $0.25 to win the 2026 World Cup, and you buy at that price. Great news, France wins. That means your trade now settles at $1, and you receive $0.75 profit per contract.

The gap between the prices on “Yes” and “No” reflects the uncertainty in the market, meaning that sentiment and liquidity are driving the price, just like in financial markets.

Where does the name Kalshi come from?

Kalshi translates to “everything” in Arabic, which is appropriate given the company’s strategy. Kalshi wants there to be a market for just about every situation in life, politics, pop culture, sports, and entertainment.

Who are Kalshi’s competitors

The prediction market industry is still relatively new, especially in the United States, but it is already competitive.

Kalshi’s main competitor is Polymarket, which is a crypto-based platform that, like Kalshi, allows users to trade on real-world events. Polymarket made some headway thanks to a sleek interface and strong user community, but it has faced regulatory hurdles in the United States.

Another rival is Predictit, which is known mostly for offering markets on political events like presidential elections, senatorial races, and more.

When was Kalshi founded?

Kalshi was founded in 2018 by MIT students Tarek Mansour and Luana Lopes Lara.

Although it was founded in 2024, Kalshi didn’t get regulatory approval from the Commodity Futures Trading Commission (CFTC) until November 2020. It was launched to the public in the following year.

Officially, Kalshi has been around for seven years, but it really started to gain steam around the 2024 Presidential Election, and then again during the Papal Conclave.

The ability to set a market for events like elections makes Kalshi a go-to resource for media to discuss the probability of an outcome during these massive events.

Will more legalized prediction markets pop up?

It is hard to pin down just how big the prediction market is, especially since it is naturally compared to the sports gambling space, but the emergence of Kalshi and some of its competitors points to this being the beginning stage of what could be quite the boom in the prediction market industry.

There are certainly things to monitor, most notably the fluid nature of gambling and trading regulations, but the momentum is certainly behind Kalshi and companies that offer similar markets.

There have also been reports that some of the giants in the sports betting space, most notably DraftKings, has expressed legitimate interest in exploring the opportunities in the prediction market industry.

DraftKings was warned against taking that route, but it’s still early days in this industry, and it wouldn’t be a surprise to see one of the gaming giants to find a way into the business. We’ve already seen DraftKings acquire a lottery company, JackPocket, in recent years.

Whether or not those days come soon, or ever, remains to be seen, but one thing is for sure: The emergence of Kalshi and other prediction markets has changed the way we look at the gambling industry.

Kalshi terms and conditions
