APPS LIKE KALSHI: 6 PREDICTION MARKET APPS WORTH TRYING IN 2026

What is the best app like Kalshi?

Polymarket is the closest comparable app — CFTC-licensed and available in 49 US states + DC. Kalshi traded more volume in July 2026 ($41.1B vs $8.6B), so compare liquidity market by market.

TL;DR:

The closest apps to Kalshi are Polymarket (second-largest US-regulated venue by volume), Rebet (mobile sweepstakes), OG by Crypto.com (crypto-funded), and offshore books for advanced users. Each makes a different trade-off on liquidity, fees, and onboarding friction.

What makes an app 'like Kalshi'?

Kalshi's appeal is simple: a CFTC-regulated US exchange with a polished mobile app and real USD via ACH. The apps below offer a similar binary-contract experience with different trade-offs on liquidity, currency, and state availability.

Certain limitations apply. The offer is available to new users only, subject to the terms and conditions at kalshi.com/tc/500. 18+ only. Restrictions and eligibility requirements apply. Event contract trading involves significant risk and is not appropriate for everyone. Please carefully consider if it is appropriate for you in light of your personal financial circumstances. Kalshi products are not available in all jurisdictions. See kalshi.com/regulatory for more information.

1. Polymarket — the closest US alternative

Polymarket is the most directly comparable app to Kalshi. It's also CFTC-regulated, traded about $8.6B in July 2026 versus Kalshi's $41.1B, and runs in 49 US states + DC (not Nevada) via its app, funded and traded in US dollars with full ID verification. The main difference: it's available in Michigan and Washington, where Kalshi isn't. (Polymarket's international site, not for US users, uses USDC.) See the Polymarket review.

2. Rebet — mobile-native sweepstakes

Rebet is the most mobile-first option on this list. It runs as a sweepstakes app (Rebet Cash, redeemable for prizes) in 38 states + DC and leans heavily on sports markets. Cleaner onboarding than Kalshi for casual users.

3. OG by Crypto.com

Backed by Crypto.com, OG is available in 42 states + DC, including New York, California, Florida and Texas, and funded directly from your Crypto.com balance. Strongest if you already hold crypto. Full review.

4. PredictIt — political markets only

PredictIt operates under a narrow CFTC no-action letter, only for political contracts, with an $850 cap per market. Niche but legitimate.

5. Manifold Markets — play money for learning

Manifold uses 'Mana' — play money you can't cash out. Useful as a learning sandbox; not a real-money Kalshi alternative.

6. Robinhood event contracts

Robinhood launched a limited menu of CFTC-listed event contracts in 2025 (Fed decisions, major sports). The selection is narrower than Kalshi's, but for existing Robinhood users it's a low-friction way in.
