You’ve probably noticed prediction markets are having a moment. Kalshi, Polymarket, FanDuel Predicts, Novig they’re all fighting for your attention, and the way they’re doing it is with genuinely solid welcome bonuses. Deposit a little, trade a little, and platforms are handing out real bonus credit just for showing up.

Good deal, right? Usually, yes. But “bonus” can mean a lot of different things depending on the platform, so before you jump in and claim the first offer you see, let’s walk through what these bonuses actually are, why they’re everywhere right now, and how to pick one that’s actually worth your time.

WHY Prediction Market Bonus?

Think of it as a “thanks for trying us out” gift from the platform. They come in a few different flavors:

• Deposit match bonuses — you put in money, they match it with bonus credit. Something like “deposit $20, get $50.”
• Trade-and-earn bonuses — place one qualifying trade above a certain size, and once it settles, the bonus lands in your account. “Trade $25, get $35” is the classic version.
• No-deposit bonuses — the rarest and easiest kind. Just sign up and verify your account, no funding required.
• Referral bonuses — send a friend your link, you both get a little something when they sign up.
• Ongoing rewards — not a welcome bonus exactly, but loyalty perks, fee rebates, or rewards for traders who stick around and stay active.

Platform	Bonus Type	Coupon Code	Bonus Amount	Qualifying Action
Kalshi	Sign-Up Bonus	SDS or LABS	$10	Complete $100 in total trades within 90 days.
Novig	Welcome Offer	ACTION	$50	Make a $25 initial purchase to unlock $50 in Novig Coins/Cash.
Underdog Predict	Registration	(Link-based)	$10	Sign up through an official partner link.
Polymarket	Referral Bonus	(No Code)	$10	Referred user must make their first deposit.
Kalshi (Sports)	Season Special	HANDLE	$10	Trade on any NFL or PGA event contract.
Novig (Sweepstakes)	Sign-Up	SOUTH	10% Off	10% off first purchase up to $100 in site credit.

One thing worth knowing upfront: most of these bonuses come as trading credit, not straight cash. That means you’ll usually need to actually use it to place trades before anything becomes withdrawable. It’s not a scam or a gotcha it’s just how the offer works but it’s worth knowing going in so nothing catches you off guard.

Why Is Everyone Throwing Bonuses at New Users Right Now?

2026 has been a huge year for prediction markets monthly trading volume has been landing in the $20–25 billion range, and legal wins for platforms like Kalshi have opened up more sports-related markets in more states. When that many platforms are chasing the same pool of new traders, the easiest lever to pull is a juicy sign-up offer. It’s the same playbook we saw with sportsbooks and crypto exchanges a few years back.

The upside for you: bonus values right now are about as good as they’ve ever been, and platforms keep refreshing their offers to stay competitive with each other. It’s genuinely a good time to be a new user shopping around.

How to Actually Judge Whether a Bonus Is Good

Not every “bonus” is worth chasing just because the number looks big. Before you commit, take a minute to check:

1. The minimum deposit or trade size — how much do you actually need to put up to unlock it?
2. Any qualifying requirements — do you need to hit a certain trade volume before you can use or cash out the bonus?
3. What form it takes — is it real cash, general trading credit, or “bonus dollars” locked to specific markets only?
4. The expiration date — a lot of bonuses quietly expire if you don’t use them within a set window.
5. Whether your state is eligible — this matters a lot with Kalshi especially, since market access can vary state by state.
6. Whether the platform is actually regulated — CFTC regulation affects both legal standing and which markets you can even access in the US.

A few minutes of reading the fine print now saves you a headache later.

The Platforms Actually Worth Knowing About

• Kalshi — The first CFTC-regulated exchange built specifically for event contracts, covering everything from politics and sports to weather and the economy. Their offers tend to be simple and easy to understand: trade X, get Y.
• Polymarket / Polymarket US — One of the biggest names by volume, with a huge spread of markets across politics, sports, crypto, and pop culture.
• FanDuel Predicts and DraftKings Predictions — The sportsbook giants moving into prediction markets, often folding their offers into loyalty programs you might already be part of.
• Novig and ProphetX — Built for sports traders specifically, with exchange-style pricing and their own sign-up credit offers.

Bonus amounts and terms shift around constantly as these platforms compete for attention, so it’s always worth a quick comparison before you commit to one.

A Few Tips to Get the Most Out of Your Bonus

• Pick the platform you’ll actually use. A massive bonus means nothing if the platform doesn’t have markets you actually want to trade.
• Actually read the withdrawal rules. Bonus credit and real cash aren’t always treated the same until you’ve met the requirements.
• Don’t let the bonus talk you into bigger trades than you’re comfortable with. Qualifying for a promo shouldn’t be the reason you take on more risk than usual.
• See if offers stack. Some platforms let you combine a welcome bonus with a referral code, some don’t worth checking rather than assuming.
• Double-check your state. Make sure the markets you care about (sports contracts especially) are actually available where you live before you sign up.

One Honest Note on Risk

“Trading event contracts is still trading there’s real money and real risk involved, and a bonus doesn’t change that. Treat any prediction market bonus as a nice head start for trying out a platform, not as free money with zero downside. Most of these offers require you to be 18+ (or 21+ in some states), and the fine print varies platform to platform, so it’s always worth a quick read before you dive in.”
