PredictionWolf is an independent guide to prediction market platforms — Polymarket, Kalshi, Manifold, Robinhood, and the smaller players coming up behind them. We exist because the existing landscape of “promo code” pages on Google is mostly stale spam, and prediction markets in 2026 are interesting enough that a serious resource is worth building.
What we do
Three things:
- Maintain a current list of verified promo codes for every major prediction market platform. We re-test every code every Monday. Dead codes get pulled within 24 hours.
- Write plain-English guides to how these platforms work, what they cost, where they’re legal, and which markets are worth your attention.
- Compare platforms honestly, including the downsides. If Polymarket has higher fees in crypto markets, we say so. If Kalshi’s sports markets are unavailable in your state, we tell you. If Manifold’s play-money model means prices are less accurate, we don’t pretend otherwise.
Why we exist
If you’ve Googled “polymarket promo code” or “kalshi sign up bonus” recently, you’ve seen the same pattern: dozens of nearly-identical pages, most written in 2022, with codes that may or may not still work. Some of them are aggregator spam. Some are content farms that have never actually used the platforms they cover. A few are real, but you have to dig to find them.
The prediction market space changes faster than that content gets updated. Polymarket returned to the US in late 2025 under CFTC oversight — most existing articles haven’t updated. The April 2026 Polymarket exchange upgrade introduced pUSD as the platform’s collateral token — most articles still describe USDC. State-level legal challenges keep shifting which platforms are available where — most “is X legal in Y” pages haven’t checked recently.
We update accordingly. Every page has a “last updated” date. We re-check the underlying facts when the platforms change. When something significant happens — a new fee structure, a new state ban, a new platform launch — we update the affected pages and add new ones.
How we make money
Affiliate commissions. When you sign up to a prediction market through one of our links, the platform pays us a small finder’s fee — typically $5-25 per successful signup depending on the platform. You get the same sign-up bonus you’d get going directly to the platform.
This is disclosed on every page that contains affiliate links, because the FTC requires it and because pretending otherwise is gross. We don’t take direct payment for editorial coverage, and we don’t publish codes that don’t work just because they pay better.
For full details on which links earn us money and our disclosure practices, see our affiliate disclosure.
Our editorial standards
Three rules we try to hold to:
Test before we recommend. Every platform we cover, we’ve actually used. Every code we publish, we’ve actually tested. Every screenshot in our guides comes from real accounts on real signups. If we can’t verify something firsthand, we say so or we don’t write about it.
Update or pull. When information goes stale, we update it or remove it. We don’t leave 2022 fee numbers on a page about 2026 fees just to keep traffic. If you find something out of date, tell us and we’ll fix it.
Disclose conflicts. When we’re paid via affiliate links, we say so. When we have personal accounts on platforms we cover, we say so. When two platforms compete and we have an affiliate relationship with both, we say so. The goal is for you to read our coverage knowing exactly what’s behind it.
What we won’t do
- Recommend platforms we haven’t used. If we don’t cover something, it’s usually because we haven’t tested it yet or it’s not legitimate.
- Publish codes we can’t verify. “Try this code, it might work” isn’t useful. Either we know it works or it’s not on the site.
- Pretend platforms are better than they are. Affiliate relationships mean we have an incentive to oversell. We try to compensate by being explicit about the drawbacks of every platform we cover.
- Help anyone bypass geographic restrictions. If a platform doesn’t operate in your state or country, we’ll tell you what your alternatives are. We won’t help you VPN around terms of service.
What this site isn’t
We’re not financial advisors. We’re not lawyers. We’re not your friend who will personally help you trade. The guides on this site are for informational purposes — they’re a starting point, not a substitute for your own research or professional advice.
Prediction markets involve real money and real risk. Most casual traders lose money, same as any trading activity. The platforms are legitimate, the bonuses are real, but neither of those facts means you’ll make money trading. Treat your initial deposit like discretionary spending — money you can afford to lose entirely.

Last thing
Prediction markets are one of the more genuinely interesting financial products to emerge in the last decade. They let you put money behind your beliefs about the world, they aggregate information from thousands of participants into a single price, and they’re often more accurate than the experts they compete with. We think they’re worth understanding, regardless of whether you trade on them.
