How to Choose a Prediction Market: A Beginner's Buyer's Guide
Last updated: September 2026 · A decision framework, not a ranked list. Looking for ranked picks? See our top prediction markets on the homepage.
Just want the ranked list?
If you already know what you're looking for, skip the framework below. Our homepage maintains the current ranked list of the best prediction market platforms for US investors, updated monthly with fees, markets, regulation, and payout speed side-by-side.

"Best" is a loaded word for prediction markets. The platform that is best for a US macro investor buying CPI contracts with a taxable brokerage mindset is not the same as the one that is best for a crypto-native trader who wants USDC and zero maker fees. A ranked list can hide that.
This guide walks you through the five decision points that actually determine which platform is right for you. At the end, you will have a short-list of one or two platforms — and you can then check our ranked picks on the homepage with real context for why one is rated above another.
The decision framework
Work through these five questions in order. Each one narrows the field.
-
Q1 · Are you a US resident?
Yes — move to Q2.
No — Polymarket (global interface), Opinion Trade, and a handful of international venues are your realistic options. Kalshi, PredictIt, and Robinhood are US-only. -
Q2 · Do you want a federally regulated platform?
Yes (recommended for beginners) — CFTC Designated Contract Markets: Kalshi, Polymarket-US via QCEX, Robinhood Prediction Markets — plus PredictIt under CFTC no-action relief. Move to Q3.
No / don't care — Opinion Trade and offshore venues open up, at meaningfully higher operational risk. Not recommended as a first experience. -
Q3 · Fiat USD or cryptocurrency (USDC)?
Fiat USD — Kalshi (ACH + debit, $10 minimum), PredictIt ($10 minimum), Robinhood Prediction Markets (uses your existing Robinhood cash), or Polymarket US (debit card, bank transfer (ACH) or wire; $1,000 minimum for wire). No crypto setup required. Move to Q4.
USDC / crypto-native — the international Polymarket app (USDC on Polygon) or Opinion Trade, neither of them CFTC-regulated; US residents can only close existing positions on the international Polymarket app, not open new ones. You will need a wallet, an on-ramp account, and ~30–60 minutes of crypto setup before your first trade. Move to Q4. -
Q4 · What do you want to trade?
Macro / economic indicators (CPI, FOMC, GDP, unemployment) — Kalshi is the only CFTC-regulated platform that lists these.
US political events — Kalshi has competitive liquidity at lower fees than PredictIt; PredictIt has the deepest historical coverage.
International political, geopolitical, sports, crypto, pop-culture — the international Polymarket app has the widest market breadth, but US residents can only close existing positions there, not open new ones; Polymarket US is the US venue.
A bit of everything, low-friction — Robinhood Prediction Markets if you already use Robinhood; Kalshi otherwise. -
Q5 · How important is tax simplicity?
Very important — PredictIt issues Form 1099 to US traders with $600 or more of net profit in a calendar year. Kalshi does not issue a 1099 for event-contract profits but provides a monthly profit-and-loss statement (Account → Tax Info); Robinhood provides an annual event-contract statement, which it says is not a substitute tax form.
Willing to self-report — Polymarket US has not said whether it issues a Form 1099-B for event-contract profits, so keep your own record of every trade from day one and be ready to report settled contracts yourself.
By the time you have answered all five, you should have one or two candidate platforms. That is the short-list to compare on the homepage rankings.
Beginner checklist before opening an account
- Confirm state availability. CFTC-regulated platforms are federally lawful in all 50 states, but a handful of states (Nevada, New Jersey, Massachusetts, Michigan, Ohio, Montana) have issued cease-and-desist letters on sports event contracts specifically. Our state legal guide has the current per-state status.
- Have the paperwork ready. US-regulated accounts need a government ID, Social Security Number (for 1099), and a US bank account. Polymarket US signs you up with a Google or Apple ID, then verifies your identity (KYC) before you can deposit or trade.
- Plan your tax flow. If you go Polymarket US, start keeping your own trade records before your first trade — it has not said whether it issues a Form 1099-B, and retroactive reconstruction is painful. Our tax guides (Kalshi, Polymarket) walk through the filing mechanics.
- Start small. Make a $50–$200 first deposit and trade three or four small positions before scaling up. Understand how contracts settle, how probabilities move, and how the fee structure hits your PnL.
- Keep a trade journal. Even a simple spreadsheet: date, market, position, entry price, exit / settlement price, PnL, and a one-line thesis. You cannot improve what you cannot measure, and the journal becomes invaluable evidence at tax time.
Common beginner mistakes to avoid
- Choosing on fees alone. Polymarket US pays maker rebates (its taker fees are about the same as Kalshi's), but it has no economic indicator markets and has not said whether it issues a Form 1099-B — fees are only one axis.
- Treating prediction contracts as sports bets. Prediction market contracts are binary derivatives you can exit before resolution at the current market price. Sports bets cannot be traded out. The mental model matters — confusing the two leads to poor position sizing.
- Ignoring tax implications until April. Especially on a platform that does not issue a 1099 (or, like Polymarket US, has not said whether it does), where you are constructing your own gain/loss records. Reconstructing a year of trading activity in panic mode at tax deadline is the single most common complaint.
- Trading every contract you see. Concentrate on two or three categories where you have some edge — macro, a specific political cycle, a narrow sports league. Breadth does not produce alpha.
Next steps
Once you have a short-list from the framework above, the next step is to compare specifics. Three places to go next:
- Our homepage — the current ranked list of top prediction markets for US investors, with fees, markets, regulation, and payout speed in one table.
- Our methodology — how we evaluate and rank platforms, so you can decide whether our weighting matches your priorities.
- Side-by-side comparisons — head-to-head comparisons of the platforms you are actually choosing between (e.g. Kalshi vs Polymarket).
