POLYMARKET ALTERNATIVES: THE BEST SITES LIKE POLYMARKET IN 2026

What is the best alternative to Polymarket?

For US traders, Kalshi is the closest direct alternative — CFTC-regulated, real USD via ACH, and strongest on US politics and economic data. Rebet and OG cover sports and crypto-funded niches respectively.

TL;DR:

The strongest Polymarket alternatives for US traders are Kalshi (real USD via ACH, CFTC-regulated, best for US politics and macro), Rebet (mobile-native sweepstakes app, strongest for sports), and OG by Crypto.com (crypto-funded, generous bonuses). Each fills a different gap Polymarket leaves open.

Why look for a Polymarket alternative?

Polymarket is one of the two global volume leaders, but it isn't always the right fit: it excludes Nevada, and some US-specific markets (politics, Fed data) have deeper books on Kalshi. The platforms below cover the gaps.

Polymarket: deposit $10, get a $25 trading bonus with code WIN

18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading is risky. 100% loss can occur. See polymarket.com/tos for more information.

1. Kalshi — best Polymarket alternative for US traders

Kalshi is the most direct Polymarket alternative for US users. It's CFTC-regulated, takes real USD via ACH, and runs in 47 states + DC. Like the Polymarket US app it's funded in US dollars; the differences are market depth and a cleaner UX.

Best for: US politics, Fed decisions, and economic data.

2. Rebet — best mobile-first alternative

Rebet is a sweepstakes-model social prediction app available in 38 US states + DC. It's mobile-native, leans heavily on sports markets, and uses Rebet Cash, a sweepstakes currency redeemable for prizes. See the Rebet review.

Best for: casual users, sports-heavy traders, and states where Polymarket or Kalshi aren't an option.

3. OG by Crypto.com — best for crypto-native traders

OG is Crypto.com's prediction market arm, available in 42 US states + DC, including New York, California, Florida and Texas. Funded entirely through Crypto.com, with a trade $25, get $25 in rewards offer for new users and tight integration into the broader Crypto.com ecosystem. Full OG review.

4. Manifold Markets — best free play-money option

Manifold uses 'Mana' (play money) rather than real cash. It's a legitimate way to learn how prediction markets work without putting real money at risk — but you cannot cash out winnings.

5. PredictIt — limited US academic exchange

PredictIt operates under a narrow CFTC no-action letter for political markets only. Position limits are tight ($850 per market) and the future of the exchange has been litigated. Useful for political junkies, not a serious Polymarket alternative.

Frequently asked questions

What is the best alternative to Polymarket?

For US traders, Kalshi is the closest direct alternative — CFTC-regulated, real USD via ACH, and strongest on US politics and economic data. Rebet and OG cover sports and crypto-funded niches respectively.

Are there any sites like Polymarket that don't use crypto?

Yes — for US users, Polymarket's own US app is funded in US dollars too. Kalshi is the leading alternative: it's CFTC-regulated, takes real USD via ACH, and is available in 47 states + DC. Rebet (sweepstakes model) is another non-crypto alternative.

Is Manifold a real alternative to Polymarket?

Only for learning. Manifold uses play money ('Mana') with no cash-out, so it's good for testing your forecasting skill but isn't a real-money replacement.

Which Polymarket alternative has the lowest fees?

Kalshi charges a fee when your trade fills and shows it before you confirm. For the Polymarket US app, check the current fee schedule in the app before you compare. Rebet's effective take-rate is higher because of the sweepstakes mechanic.

Is PredictIt still operating?

Yes, under a narrow CFTC no-action letter for political markets only. Position limits are capped at $850 per market, making it unsuitable for serious size.
