The #1 question I get from people new to prediction markets is what should I be doing to make money. That’s no surprise given the way these platforms are advertising to people, but I think most understand there’s no free money here. Particularly those who have experience with sports betting. And so I think it’s important to be truthful about prediction markets as it’s far from easy money. Most people who trade them will lose, just like most sports bettors lose. If someone tells you otherwise, they’re selling something.
But if you have experience sports betting, and I’m guessing you do, prediction markets offer a few edges that genuinely don’t exist in the sportsbook world. I’ve spent the past six months researching and building tools for these markets, and these are the teachable strategies that actually hold up.
1. Arbitrage Across Platforms
This is the closest thing to free money you’ll find, which is exactly why it’s hard to find at scale.
The concept is simple: Kalshi has a contract priced at 60 cents YES. Polymarket has the same outcome priced at 55 cents YES. You buy YES on Polymarket, buy NO on Kalshi (which is effectively paying 40 cents), and you’ve locked in a 5-cent profit regardless of what happens. No risk. Just math. In theory it’s very simple and easy to execute on. In practice, it’s messier than that. You’ve got capital locked up on multiple platforms. Fees eat into your margins. There’s resolution risk that the two markets don’t settle the same way. And the good arbs get snapped up fast.
There are bots that will beat you to the arbitrage 100% of the time when it’s a clear market across platforms (i.e., BTC price by X date in the future). But the real opportunity comes when there is built-in complexity that bots can’t automatically solve. This may be slightly different wording in the markets, or minimal differences in market characteristics, such as a long-term market resolving a day later. Things where the arbitrage can still be relatively safe and +EV, but it takes a manual assessment to determine the opportunity. If this is something that interests you, let us know in Discord as we’re going to be releasing a tool to help you find arbitrage soon.
2. Winners can actually Win
This isn’t a strategy so much as a structural advantage, but it matters more than most people realize. If you’ve bet sports seriously, you already know the deal. You find an edge, you start winning, and then one morning you open your app and your limits have been crushed to $20. Or your account is just gone. Sportsbooks don’t want winners and don’t have to let them play.
Prediction markets don’t work that way. There’s no bookie on the other side deciding you’re too sharp. You’re trading against other participants on an exchange. Nobody’s going to limit you for being good.
On top of that, the vig is usually lower. A standard sports bet has you laying -110 on both sides, a built-in 4.5% house edge before you even start. Prediction market fees vary by platform, but you’re generally paying a fraction of that. Over hundreds of trades, that difference compounds into real money.
I want to be clear: better pricing doesn’t mean you’ll be profitable. You still need an edge. But if you already have one, prediction markets let you actually keep more of what you earn instead of bleeding it back to the house. For anyone who’s been limited or closed out by a sportsbook, that alone should be enough to take this seriously.
3. Find your Niche and Master It
Here’s something most people don’t think about: who’s on the other side of your prediction market trade?
A lot of the time, it’s a market maker providing liquidity across hundreds or thousands of markets. They’re running models, sure. But their models are built for breadth, not depth. They need to be approximately right across everything. They don’t have time to become an expert on San Francisco microclimate weather patterns or the mentions market of a specific NFL commentator.
This is the same dynamic as prop betting in sports. Sportsbooks hang thousands of player props every day. Their lines are good enough on the popular stuff, but the further you go into the weeds, the softer those lines get. And they just offer so many that inevitably they’re going to be mispricing a couple. Books just can’t invest the same attention into every single line.
Prediction markets have the same vulnerability, except the “props” are things like regional weather outcomes, specific individual mentions markets, niche political races, or obscure economic indicators. If you’re willing to become the person who knows more about Joe Buck’s Monday Night Football commentary than anyone else pricing that market, you will find mispriced contracts. That’s no guarantee of profit (you still have to be right), but you’re playing a game where your opponent is spread thin and you’re not.
4. Don’t Just Focus on Outcomes - Think about the Price Movement
Most people approach prediction markets the same way they approach sports betting: pick a side and wait for the result. But prediction markets give you something sportsbooks never have: the ability to exit your position at any time, at a fair price.
This changes how we should be thinking about trading. Consider the market for the Giants to win their division in 2026 and let’s say it’s at 8c. They finished last in their division, so they’ll at least have an easier schedule for the year, which will already be incorporated in any odds to win their division. But when the schedule is fully announced, you may realize their easiest games are front loaded and they could realistically start the year 3-0.
You don’t necessarily think they’re actually going to win the NFC East, but at 8c you see there is a strong likelihood of a hot start, and if they get to 3-0 or even 2-1, the market might overreact and that 8c contract shifts to be worth 16c. That’s a 2x outcome on a trade with minimal downside in that short timeframe.
This is how traders think about financial markets, and it’s a completely foreign concept to most sports bettors. Rather than only thinking about predicting the final outcome, you’re predicting what will happen to the price between now and resolution.
The real edge here is in long-duration contracts trading at low prices. A contract sitting at 4 cents that doesn’t resolve for six months has a lot of time for things to change. If you have a thesis about why that contract is underpriced, not simply that it’ll resolve YES, but that specific upcoming events will push the price up, you’re playing a different game than most others staring at the resolution date.
This takes more work than just picking a side. You need to think about catalysts, timelines, and what information the market is and isn’t pricing in. But it’s also where the biggest opportunities are, because most retail traders simply aren’t thinking this way.
5. Making vs Taking
Every trade you place on a prediction market puts you in one of two roles, and most people never realize they have a choice.
When you take, you accept a price someone else already posted. You hit the existing bid or ask and get filled instantly. When you make, you post your own price and wait for someone to come to you. As a sports bettor, you've only ever been a taker. The book sets the number and your only decision is whether to accept it. You've never once had the option to say "I'll bet this, but only at my price." Prediction markets give you that option on every contract.
This matters for two reasons.
First, the spread. Thin markets often have wide gaps, where a contract might show a 6-cent bid and a 10-cent ask. Take it and you pay 10. Post a bid at 7 and let it sit, and you might get filled at 7 instead. That 3-cent difference is pure edge, and it's the difference between paying the spread and collecting it. Over hundreds of trades, capturing the spread instead of crossing it compounds the same way the vig does, just in your favor.
Second, the fees. Platforms want makers, because you're providing the liquidity they'd otherwise have to pay for. So they charge you less for it. On Polymarket, makers pay nothing and can even earn a rebate. On Kalshi, maker fees run a fraction of what takers pay. You're getting paid, or close to it, to be patient.
Making isn't free money either. Your resting order can get picked off (i.e., if news breaks and the market moves against you, your stale bid is the first thing that gets hit, and now you're holding a losing position you never wanted). And plenty of the time your order just sits there unfilled while the move happens without you. But making rewards patience and discipline, which is a different game than the instant-action habit sports betting builds.
But this ties into everything above. In the niche markets from #3, where you know fair value better than the market maker on the other side, you shouldn't be crossing the spread to take their price. You should be posting your own and making them come to you. And for the price-movement trades in #4, making is how you build a position cheaply before the catalyst hits.
None of these are get-rich-quick strategies. If that’s what you’re looking for, I can’t help you. But if you’re a sports bettor who’s tired of getting limited, tired of laying -110, and looking for markets where skill actually gets rewarded, prediction markets are worth your time.
