Kalshi Market Trends: Winning Strategies and Key Risks

UPDATE: This article got picked up in the news by Bloomberg! Check it out: Bloomberg Article

Been thinking about the classification question around event contracts for a while. Pulled all of Kalshi's NFL moneyline trade data across the full 2025 regular season and reconstructed passive LP exposure game by game.

The short version: LPs aren't neutralizing inventory and capturing spread. They're accumulating directional outcome exposure that persists through settlement, and profitability correlates with managing flow imbalance rather than eliminating it. That's not a market making return profile — it's closer to how a sportsbook or insurer makes money.

Curious whether anyone in this space has thought about this distinction and what it implies for how these markets should be regulated.

Interesting read. I wonder if that varies by market type. Something like NFL games probably has well established/modeled true probabilities. Something like who will be next Fed chair probably doesn’t.

Briefly:

> joined kalshi only 7 days ago
> already pushed over $2.8m in volume
> made roughly $350k
> sitting at an insane 95% win rate

most of his activity is around football prediction markets and the numbers are honestly crazy

I used to think only polymarket had these high performing bot and data driven traders but it looks like kalshi has some monsters too.

You are mostly betting against bots. Remember that.

Hey everyone I wfh and a couple weeks ago I got obsessed with BTC 15 minute market

I came up with some pretty simple indicators but I back tested them from 5 years of data and am using Claude code to scrape kalshi crypto market prices constantly to further refine my strategy.

The image provided is from a paper trading dashboard, and I have a couple strategies I’ve been developing that look promising, but I’m hesitating on pulling the trigger fully even though I’ve let some run for a couple days with real money because I’m kind of altering the strategy a little. They made small percentages which I am happy about but I’m eyeing some of my paper trading bots that are a lot more profitable more right now… the more profitable strategies lose more but win enough… I think I got a good little sweet spot going with it…

Anyways I don’t have a BS course or anything to sell, and also wonder if I should even tell anyone the strategy like at all because maybe I did really find something, or maybe I’m just an idiot :/

Anyways my friends aren’t super interested in hearing about it, work sucks, personal things… I digress… and I think I’d just love someone to talk to about the details with it, maybe someone that knows more than me because I came up with everything on a whim, but I’ve educated myself a little more… and either way… it looks like something that could work…

Anyways, I’ve pulled the kalshi order book and have scraped and scraped and scraped, still scraping via railway, and have literally run 10s of thousands of simulations trying to perfect this but have learned all about slippage and api delays and blah blah blah… anyways, if someone wants to talk shop about btc 15 minute market I may or may not have something, just would be cool to talk to someone.

There are a few seconds of latency between what you are seeing on Kalshi vs. what the market makers see. Just like in sports. So these market makers are reacting to price movements before you even see them. Additionally, as the time remaining decreases, the market will become more volatile. Especially if the current price is extremely close to the target price.

Over the past few days ive noticed the market being super skewed in either direction while the price is within a $50 margain, for instance 85% at 63,927 with a 63,911 target. Previously these close margains would have a 60-40 or lower adjusted price. Ive also seen the odds flipping intensely (91%-33%) within less than a second. Has anyone else noticed this change lately?

I’ve been running a live bot on Kalshi weather markets for about a week. The key thing I learned: the ensemble weather model (31 independent GFS runs via Open-Meteo, free API) gives you actual probability distributions, not just a point forecast. Most Kalshi weather traders are pricing based on gut feel or Weather.com. The data gap is the edge. Biggest gotcha so far: penny contracts at $0.05 look amazing on percentage edge but are traps. Raised my minimum price filter to $0.10 and the trade quality improved.

Kalshi makes money on both sides. They don’t give a shit where the line goes.

Yeah, absolutely. The scumfuck owners of Kalshi make a shitload of money off of people vulnerable or stupid enough to use it.

Yes, but the distribution is brutal.

A small number of people make serious money. Most break even or lose slowly to fees. It's not rigged -- it's just that the winners usually have an actual edge: better data, faster execution, or they're trading markets most people ignore.

The ones I've seen do well consistently tend to focus on one niche and go deep on it rather than spreading across everything. I trade weather markets specifically -- daily temperature highs and lows -- using meteorological model data to find spots where the market price is wrong. It's boring, repetitive, and it works.

The people who lose are usually treating it like a casino. The people who win are treating it like a research problem.

So yes -- real money, real edge required.

If only there were something structurally different between market making for a game that concludes in a few hours and market making for a security that exists in perpetuity.

Hi,

To start, I have been using Kalshi for a little less than a year. made my initial deposits back in March. And since then, I've had no problems. I verified my account with my valid state driver's license and a selfie. I have a passkey set up with two-factor authentication, and I figured that everything was safe.

Last Monday, I checked my Kalshi account and noticed there was a request to withdraw funds, which I never made. I contacted Kalshi support and immediately told them it was not me and that it was fraud. They asked me to re-verify my account and sent me a QR code to upload a copy of my ID and take a selfie. Unfortunately, because I am on iOS 27 and am a beta tester, the link to open my camera on my phone, that they sent me, did not work. I contacted Kalshi Support and told them. Kalshi Support was silent. They then came back and told me that my account was frozen, I could no longer use Kalshi services, and that I was a fraudster! That completely perplexed me, so I kept asking what they were talking about. I then logged out of my phone and logged into my account on my wife's phone, which she's running iOS 26. I was able to use that link and upload a new copy of my state ID DL and a selfie. Support didn't care. They told me they've done everything they could and their decision was final. I continued to go back and forth. They never recognized or acknowledged that I had uploaded an original verification photo and ID. Support then emailed me my conversation and included pictures of the random individual trying to access my account and my initial verified information! I confirmed with them that the first three pictures were me, but the last three pictures were not me (it's obvious, our skin tones are different . Kalshi Support told me that they were going to contact the local authorities, to which I told them, please do so. Kalshi Support told me to make my withdrawal, and that was it. Now they will not talk to me at all.

Six days ago, I decided to withdraw the cash balance of my Kalshi account to my bank account. The transaction went smoothly. The only problem is that somebody had changed my account to a different account, one that I did not own, and the money went to that account. In the meantime, I contacted Kalshi to once again tell them that, and they completely disregarded everything I sent and said in the chat. I have posted in the Kalshi support mega thread four different times, and each time the post has been removed. I have contacted different individuals throughout the organization via email, hoping to receive some type of response. NOTHING!

I contacted my bank and have filed a complaint with them against Kalshi. I don't know how it's going to turn out, but at least I have a bank looking into this. I also have emails, photos, screenshots, you name it. I'm really not looking for any advice; I just want people to be aware that this is happening and what you can possibly do about it. Kalshi is stealing! Thank you for taking the time to read this. Suggestions are welcome.

What a ridiculous reality we live in. Never did I think I'd be trading on reality TV markets lol. I started out in this market by tailing a good trader (GoodHombre) who has been going in big on the Trinity & Bryce ticker. Then, I realized that this was a very inefficient market & I could take advantage of it a bit more by trading both sides of the other participants. At this point, trading has cooled down, most of my profit is cashed, and I don't think I will make any more profit, so I feel comfortable sharing it. One of my favorite plays yet. Happy to answer any questions, within reason.

This is literally how Options market making works. People buy/sell insurance often overwhelmingly one way in specific instruments and they are compensated for their ability to take on that risk.

Leaving aside any discussion of prediction markets and the morality of those, do people make big money on Kalshi?

sure, people insider trade on there all the time

That is the beauty of Kalshi. There are several markets with a ton of profit potential. Avoid combos and sports and keep discovering these +EV plays! Great work!

+$65.89 total profit
+11.79% account growth
140/170 winning trades (82.35%)

The biggest positive is consistency. Most days were green, and the account grew from $559 to $624.89 without needing one massive lucky hit.

That said, the annualized number looks ridiculous because it assumes the same daily return compounds perfectly all year, which obviously won’t happen. Markets change, volume can dry up, and one bad day can wipe out a lot of small wins if risk isn’t managed.

Still, this is a solid start. The goal now is to keep scaling slowly, stay disciplined, and focus on repeatable edges instead of chasing.

any advice of finding ineffiencies like this? i have all the time in the world and have tried countless strategies but somehow never know more than the average kalshi user

I've been working primarily around sports prediction markets, especially cricket and basketball, and I'm interested in finding a few other traders/researchers to build something together.

The idea is to combine different areas of expertise, develop and test strategies, track results properly, and see if we can build a genuinely strong track record over time.

I'm particularly interested in people who are active in prediction markets and have strengths in areas I don't—football, boxing, politics, macro, quantitative research, execution, etc.

Not selling anything or looking for clients. Just looking to meet sharp people who are interested in building.

If that's you, feel free to comment or DM.

I’m trying to understand the Islamic finance distinction.

Kalshi involves taking positions on future outcomes and is often labeled gambling (maisir). But when someone invests in stocks or the S&P 500, they’re also risking money based on the expectation of appreciation and profit. Essentially, you are betting on the outcome, hoping that there is appreciation overtime.

Both involve uncertainty and potential gain or loss.

So what is the Shariah distinction?

Ownership of a real asset? Participation in productive economic activity? The structure of the contract? Something else?

Genuinely looking for the fiqh reasoning behind why one is impermissible while the other is generally allowed (with halal screening).

Thoughts?
