Compared by Poll
Kalshi is a federally regulated exchange where event contracts trade on an order book. The apps below cover the rest of the category: rival regulated venues, event contracts inside brokers you already use, a free play-money option, and one app for the bet no exchange will ever list.
Poll is our product and appears first in this guide. We say plainly what it does not do, state where every other app is better, and link the first-party sources behind each claim. For the direct head-to-head, read Poll vs Kalshi in full.
Short answer
Bets between friends
Write the question yourselves, share one link and settle it as a group.
Global liquidity
The deepest order books on public events, plus a separate regulated US app.
Inside a broker
Event contracts from several regulated exchanges without another account.
Economic data
Interactive Brokers' own exchange for rates, inflation and climate contracts.
The splits that matter: whether real money is involved, who stands behind it while the outcome is open, and what each venue actually covers.
| App | Best for | Real money | Regulation | Coverage | Platforms |

| Crypto.com | Regulated sports event contracts | Yes, US dollars | Runs its own CFTC-registered exchange and clearinghouse | Sports first: winners, spreads and totals across ten-plus sports | iPhone, Android and web |

How we compared them
Product sites, help centres, regulator filings and store listings are the evidence. We do not use another comparison blog to fill a gap in an app's own documentation.
We compare who lists the contracts, whether real money is involved, who holds it while the outcome is open, and what actually happens when you win.
Every entry has its own checked date below. This category moved fast through 2025 and 2026, so an undated claim about any of these apps is not useful enough.
A clearinghouse-backed exchange and a play-money community are right for different people. Each entry says who should pick it and the drawback to understand first.
The shortlist
01 · Best for cash bets on your own question with people you know
Bet with friends on anything
Poll is our product
Poll does the one job no exchange will: a cash bet on a question only your group cares about. You write it, share one link, everyone stakes, and the people who wagered vote on the result.
You bet the people you actually know instead of trading against strangers, and your friends take the other side rather than a book. On supported cash bets the stake is held until the group settles it, so the winner never chases payment.
Poll is our product and it is not a regulated exchange. There is no clearinghouse, no order book and no early exit: a bet runs to its result. Cash availability depends on the surface and location.
02 · Best for deep liquidity on public events
The World's Largest Prediction Market
Polymarket is the biggest prediction market in the world and the obvious first stop if Kalshi's menu or pricing does not suit you. It now runs two separate products, one global and one regulated for the US.
The deepest order books in the category, so prices carry real information and you can exit a position before the event resolves. Makers are not charged, and the US product now sits on a CFTC-licensed exchange.
The two products have separate accounts: the global site is unavailable in the US, and the US app opened with a narrower menu and iOS first. Like Kalshi, a markets team decides what gets listed.
03 · Best for event contracts next to your stocks
Prediction markets hub
Robinhood's prediction markets hub is how many people trade Kalshi contracts without knowing it. Orders route to several CFTC-regulated exchanges from inside the broker app you may already have.
No new account, no new balance to fund, and contracts sourced from more than one regulated exchange, so the menu does not depend on a single venue's listing decisions.
It is a distribution layer, not an exchange. You trade what the partner venues list, you cannot create anything, and specific contracts come and go with those suppliers.
04 · Best for contracts on economic data and climate
Forecast contracts from Interactive Brokers
ForecastEx is the most Kalshi-like entry here in structure: its own CFTC-regulated exchange and clearinghouse, run by Interactive Brokers and traded through its ForecastTrader platform.
It leans into economic data, rates and climate rather than sport, and Interactive Brokers pays interest on capital tied up in open event contract positions, which nothing else on this list does.
The matching mechanism is unusual: no sell orders, only Yes and No bids that pair when they total just over a dollar. The menu is narrower and drier than Kalshi's.
05 · Best for regulated sports event contracts
Sports event contracts and the OG platform
Crypto.com was the first to offer sports event contracts in the US and now runs a dedicated sports platform on its own CFTC-registered exchange, the same venue FanDuel's event contract product plugs into.
If Kalshi's appeal for you is specifically sports, this is the most direct substitute: a regulated venue built around game winners, spreads and totals rather than a general event catalogue.
It is sports-first, so breadth is thinner outside that. Several state regulators contest sports event contracts as a category, and the fight is still moving through the courts.
06 · Best for play-money questions anyone can create
Play-money prediction markets
Manifold is the free way into this category. Anyone can create a market on anything, the community trades it in mana, and nobody's bank account is involved at any point.
Permissionless creation is the feature no regulated exchange can offer. It is the easiest place to test whether you enjoy this kind of trading before putting real money on a regulated venue.
Its real-money sweepstakes programme ended in March 2025 and remaining balances were converted to mana. Winning earns leaderboard position, not money.
01
Every exchange on this list has a team that decides its menu. If the thing you want to bet on is an argument inside your group, you need a product where you write the question yourselves.
02
A CFTC-regulated venue with a clearinghouse is a real consumer protection. Manifold and Poll do not offer it, and both say so.
03
Crypto.com is sports-first, ForecastEx is data-first, and Kalshi and Polymarket sit in the middle. Match the venue to what you actually trade.
04
An order book matches you against a crowd. A bet between friends has a name on the other side. Very different products serve those two wants.
Common questions
The closest structural matches are ForecastEx and Crypto.com's exchange, both CFTC-regulated venues with their own clearinghouses. Polymarket's regulated US app competes on the same ground, Robinhood routes contracts from several of these venues, Manifold covers the free end, and Poll handles the bet no exchange will list: one between people who know each other.
They compete directly now. Both list event contracts that trade on an order book, and both operate CFTC-licensed venues in the US. Polymarket's global site is deeper and crypto-settled but unavailable in the US, while its separate US app launched more recently with a narrower menu.
Kalshi matches you against whoever is on the order book, so it cannot host a bet between two specific people. Poll is built for that: write the question, share one link with your group, everyone stakes, and the people who wagered settle the result together.
Yes. ForecastEx is Interactive Brokers' CFTC-regulated exchange, Crypto.com runs its own CFTC-registered exchange with sports event contracts, Polymarket US operates on a CFTC-licensed exchange it acquired, and Robinhood's hub routes to several of these venues.
Manifold is the best-known free option. It runs entirely on mana, a play-money currency, and lets anyone create a question rather than waiting for a markets team to list one. Nothing can be cashed out, which is either the drawback or the point.
Not on a regulated exchange: their teams create every listing. Manifold allows it with play money. If you want real money on a question of your own, Poll lets you write it and settle it with the people who joined, without an exchange in the middle.
