Robinhood Event Contracts: How They Actually Work
Robinhood didn't build a prediction market. It built an on-ramp to one, and that distinction explains almost everything about how these contracts behave.

Robinhood's event contracts are yes/no bets that settle at zero or one dollar, priced in cents that read like probabilities. Robinhood doesn't run the market itself. It routes orders to a CFTC-regulated exchange through its derivatives arm, acting as the distribution layer. That makes it the retail front door to the same plumbing Kalshi runs.
When Robinhood added event contracts to the same app people use to buy stocks, a lot of readers assumed the company had launched its own prediction market. It didn't. Understanding what Robinhood actually built, and what it deliberately didn't, is the fastest way to make sense of these contracts and where they sit in the broader landscape.
What a Robinhood event contract actually is
An event contract is a binary claim. It pays a fixed amount if a specific outcome happens and nothing if it doesn't. Contracts trade somewhere between one cent and ninety-nine cents each and settle at either zero or one dollar at resolution.
That pricing is the whole trick. If a contract trades near sixty cents, the market is implying roughly a sixty percent chance of that outcome, because that is what a rational buyer would pay for a coin that pays a dollar. The price is a probability wearing a dollar sign. You are not buying a share of a company or a slice of an index. You are buying a yes-or-no position on a question that has a defined resolution date and a defined source of truth.
Because these settle to a fixed value, the math is cleaner than a stock. Your maximum gain and maximum loss are both known the moment you enter. There is no open-ended downside the way there is when you short an asset.
Why Robinhood doesn't run the market itself
Here is the part that trips people up. Robinhood is not the exchange. In the United States, event contracts on real-world outcomes are regulated as derivatives, which means they have to be listed on a venue overseen by the Commodity Futures Trading Commission.
For event contracts, Robinhood routes orders to such a venue rather than acting as one. It clears them through its own derivatives arm, which functions as the intermediary that carries your position. Robinhood is the storefront and the plumbing to the exchange. It is not the order book itself.
This structure has history. When Robinhood first offered contracts on a presidential outcome, it worked with a regulated exchange built for that purpose. Its broader event-contracts hub later ran on top of Kalshi's exchange. The brand on the screen is Robinhood. The market underneath is licensed infrastructure that Robinhood connects to.
That separation matters for a practical reason. The prices you see in Robinhood are the prices on the underlying exchange, shared with everyone else trading that same market through other doors. Robinhood is a large door, not a separate room.
Kalshi, Polymarket, and where Robinhood sits
It helps to sort the three names most people hear into their actual roles.
- Kalshi is an exchange. It is CFTC-regulated, based in the US, and it operates the order book where many of these contracts actually trade.
- Polymarket grew up as a crypto-native venue that historically was not open to US retail traders, and it has been working toward regulated US access through a licensed exchange it acquired. Its liquidity and its catalog have often looked different from the regulated US venues.
- Robinhood functions as a distribution layer for event contracts, not as the underlying exchange. It puts a regulated exchange in front of a very large retail audience.
So when someone compares Robinhood to Kalshi, they are often comparing a front door to the building it opens into. The more useful comparison is between the exchanges themselves, because that is where the contracts, the rules, and the settlement live.
What the retail on-ramp changes
Distribution is not a footnote. Putting event contracts next to stocks in a mainstream app pulls in traders who would never have opened a dedicated prediction-market account. More participants can mean tighter spreads and deeper liquidity on the shared exchange, which tends to make prices a little more informative.
It also flattens the learning curve, which cuts both ways. A cleaner interface can hide the fact that these are leveraged-feeling, all-or-nothing instruments with fees and resolution rules that reward reading the fine print. The contract resolves on a specific criterion, not on your interpretation of the news, and that criterion is worth checking before you ever place an order.
The larger takeaway is that the retail door and the exchange are separate things. Once you see that, fragmentation stops being confusing. The same question can trade in more than one place at slightly different prices, and that gap is the interesting part.
This is where watching more than one venue earns its keep. Delta Arc's Prediction Markets product pulls the board across Kalshi and Polymarket into a single view, so you can see how a given question is priced across the landscape rather than through one app's window. Next time, we will walk through how those cross-venue price gaps open, and what usually closes them.
