Both Kalshi and Robinhood now offer prediction market trading, but the experience is very different. Kalshi is the dedicated prediction market exchange; Robinhood is the brokerage that added event contracts to its app. Here's how they compare for different types of traders.
Quick comparison
- Kalshi: CFTC-regulated dedicated prediction market exchange. Full market catalog, API access, advanced order types.
- Robinhood: Brokerage with integrated event contracts. Curated market selection, familiar mobile interface, unified portfolio with stocks and crypto.
Available markets
Kalshi wins on selection. As the dedicated exchange, Kalshi offers hundreds of markets across politics, economics, weather, entertainment, sports, and more. New markets launch frequently.
Robinhood offers a curated subset. Robinhood focuses on the most popular, high-liquidity markets. Good for casual traders, but power users may find the selection limited.
Fees comparison
- Kalshi: Per-contract trading fees based on price and order type. Maker fees are lower than taker fees. Free ACH deposits and withdrawals.
- Robinhood: Known for commission-free trading on stocks. Check current fee structures for event contracts specifically, as they may differ from equity trading.
Compare the actual contract before choosing a venue
A platform-level comparison is only the first step. Before trading, confirm that the contract available in each interface has the same event, outcome, deadline, and settlement source. Similar titles can hide different rules. One contract may resolve from an official announcement while another depends on a specified data release or a different cutoff time. Those differences matter more than which app has the simpler navigation.
Next, inspect the executable price rather than the headline probability. Check the best bid and ask, the number of contracts available near that price, and any platform fees that apply to the order. A market displayed at 60% may cost more to enter once spread and limited depth are included. If you expect to exit before resolution, compare the order book again because the ability to close a position depends on other traders being available.
Account and research workflow
Robinhood can be convenient for users who already keep assets and cash in the brokerage, while Kalshi gives prediction-market-focused traders a broader research and order-entry environment. Convenience does not determine expected value. Choose the interface that lets you verify rules, monitor positions, and execute the intended order without skipping risk checks. Availability, identity verification, deposits, withdrawals, and product access can also vary by user and jurisdiction, so confirm the current requirements on the platform before funding an account.
Whichever interface you use, write down the market price, your probability estimate, the evidence behind it, and the maximum amount you can lose. Revisit that note when new information arrives. This creates a repeatable process and prevents the familiar interface of a brokerage—or the larger catalog of a dedicated exchange—from becoming a substitute for market analysis.
