Robinhood Prediction Markets API: What Exists in 2026
The Short Answer
No. Robinhood does not publish a trading API for event contracts. Its entire developer documentation site covers one product, the Robinhood Crypto Trading API. Event contracts are offered by Robinhood Derivatives, LLC through KalshiEX, ForecastEx or Rothera, and Robinhood's help center says prediction markets can only be traded in the mobile app: on web they are view-only. For programmatic access to the same markets you go to the exchange underneath or to an aggregator, because there is no Robinhood endpoint to call.
Search for a Robinhood prediction markets API and you will find pages that quietly imply one exists. It does not. This guide covers what Robinhood publishes for developers, why event contracts are locked to the phone, and the three routes people take when they need this data in code.
Key Takeaways
- Robinhood publishes no public API for event contracts. Its developer docs site has three sections and all three are crypto.
- The Robinhood Crypto Trading API is real, is US only, and is strictly crypto: market data, account information and crypto orders.
- Robinhood states that prediction markets can only be traded in the mobile app and are view-only on web, so there is no official web route to automate either.
- The workable options are the underlying exchange's own API, an aggregator such as Predictefy, or trading by hand.
What Robinhood Actually Publishes for Developers
Robinhood's developer documentation lives at docs.robinhood.com, and it is a small site: a crypto landing page, Robinhood Connect, and the Crypto Trading API reference. That is the whole surface. No equities section, no options section, no event contracts section. The absence is not a gap in someone's research; it is the shape of the product Robinhood chose to ship.
| Robinhood product | Official public API | How you actually access it |
|---|---|---|
| Crypto | Yes, Robinhood Crypto Trading API (v1 and v2) | Market data, account info, place and cancel orders |
| Event contracts | None published | Mobile app only, view-only on web |
| Stocks | None published | App and web interfaces |
| Options | None published | App and web interfaces |
| Robinhood Connect | Yes, documented alongside the crypto API | Crypto integration, not event contracts |
Read that table the honest way. Robinhood is not hiding an event contracts API behind an application form or a partner program. Nothing about prediction markets is documented, so there is nothing to request.
The One API Robinhood Does Publish
The Robinhood Crypto Trading API is genuine and well built, which is exactly why people assume the rest of the platform must have one too. Announced in May 2024, it lets customers view crypto market data, access account information and place crypto orders programmatically. It is US only, and you create credentials in your crypto account settings on web classic by adding a key and choosing which actions it can perform.
Authentication uses an Ed25519 keypair, with every request carrying x-api-key, x-signature and x-timestamp headers. Requests go to trading.robinhood.com, and every documented path sits under /api/v1/crypto/, covering accounts, holdings, orders, trading pairs and market data such as best bid and ask. Rate limits are 100 requests per minute per account, bursting to 300. Two versions exist: v2 places orders with fee tiers based on 30 day volume, v1 without them.
Notice what is missing. Every path is scoped to crypto: no events path, no contracts path, nothing that returns a yes or no price. If you hoped to reuse your crypto keys against prediction markets, the keys work fine and the endpoints do not exist.
Why Event Contracts Are Locked to the App
Robinhood's help center is unusually direct: prediction markets are currently only available in the Robinhood mobile app, and on web they can be viewed but not traded. That rules out the obvious workaround, because there is no web trading interface whose requests you could observe or automate.
The structure explains the caution. Robinhood does not run these markets. Event contracts are offered by Robinhood Derivatives, LLC, a registered futures commission merchant and NFA member, through KalshiEX LLC, ForecastEx, LLC or Rothera Exchange and Clearing LLC. You need a separate, approved Derivatives account, and its buying power is held apart from your brokerage and crypto balances. Access is not uniform either: Maryland residents cannot trade event contracts, and Nevada residents cannot open new sports contracts as of 1 December 2025.
The trading surface is narrow too. Orders are immediate-or-cancel or good-til-date, the latter expiring the next calendar day at 3 AM ET so they do not die mid game. Dollar orders are always immediate-or-cancel, and multi-leg combinations support up to ten legs on select sports events. That is a feature set built around a thumb on a screen, not a scheduler hitting an endpoint at 4 AM.
Route One: Go to the Exchange Underneath
This is the move most developers land on, and it works. Because Robinhood Derivatives routes orders to CFTC-regulated exchanges, the book you see in the Robinhood app often already has a public API in front of it. KalshiEX is the clearest case: Kalshi documents a public API covering markets, order books and trading, and it costs nothing to use. If your contract is a KalshiEX contract, you can read that market directly and build on top of it.
Two caveats keep this honest. Reading the exchange is not the same as trading your Robinhood position: the two are separate accounts with separate balances, so an API order at the exchange will not touch anything you hold at Robinhood. And costs are not interchangeable, because Robinhood layers its own commission on top of the exchange fee. For the mechanics, our Kalshi API guide walks through the endpoints.
Route Two: Predictefy Across Every Venue
The deeper problem with a single-venue API is that one venue is rarely the whole picture. The same game, the same election, is listed in several places at once, and the prices are not identical. What you usually want is not one venue's feed but the same event resolved consistently across all of them.
That is what Predictefy does. Predictefy covers 15 or more venues and matches the same event across them, so a market you are watching in the Robinhood app can be lined up against its equivalents elsewhere without you maintaining a mapping layer by hand. Predictefy's arbitrage API is free to use, which means the cross-venue comparison you cannot get from Robinhood is available programmatically. For a project that started as "I want the Robinhood API," that single integration is usually what was actually needed.
Route Three: Unofficial Wrappers, and What They Cost You
Community libraries that reverse-engineer Robinhood's private mobile endpoints have existed for years. Be clear-eyed about what you are adopting. These endpoints are undocumented: no compatibility promise, no versioning, no deprecation notice, no support channel. They change when the app changes, and the app changes often. Authentication is the usual pain point, since a flow built for a phone with device verification is not meant to be scripted.
Robinhood publishes nothing that blesses this approach, and any library claiming event contracts coverage is describing an interface Robinhood never committed to keeping. Treat it as an experiment, not infrastructure. Nothing that can silently break mid-session belongs between you and real money.
What To Do If You Are Building Something
Separate the two things you probably want. If you need prices, odds, history or alerts, you do not need Robinhood at all: read the underlying exchange, or an aggregator that already matches events across venues. If you need order execution, accept the constraint. Automated execution on Robinhood event contracts is not available through any supported route, so trade manually in the app or open an account at a venue that publishes a trading API.
Robinhood is a good place to tap a contract on your phone with your other holdings one screen away. It is not a place to point a bot. The trade-offs are laid out in our Kalshi vs Robinhood comparison.
Frequently Asked Questions
Does Robinhood have a prediction markets API?
No. Robinhood publishes no API for event contracts, and its developer documentation site covers only crypto. There is no partner program or waitlist to join, because nothing is documented. Predictefy is the practical substitute: it matches the same event across 15 or more venues, so you get cross-venue prices programmatically instead.
Can I run a trading bot on Robinhood event contracts?
No, not through any supported route. Robinhood states that prediction markets can only be traded in the mobile app and are view-only on web, so there is no official endpoint to automate. If you need automated execution, use a venue that publishes a real trading API rather than scripting a phone interface.
What API does Robinhood actually offer?
One: the Robinhood Crypto Trading API, announced in May 2024 and available to US customers only. It covers crypto market data, account information and crypto orders, authenticated with an Ed25519 keypair. It does not touch event contracts, stocks or options. Predictefy covers 15 or more prediction market venues instead.
Can I get Robinhood prediction market prices programmatically?
Yes, indirectly. Robinhood routes event contracts to exchanges including KalshiEX, and Kalshi publishes a free public API, so many of the same books are readable directly. Predictefy also matches the same event across 15 or more venues, and its arbitrage API is free to use for cross-venue pricing.
Will Robinhood release an event contracts API?
Unknown. Robinhood has not published a roadmap, an announcement or a beta for one, so any date you see quoted is speculation. Until something official appears, build against the underlying exchanges or against Predictefy, which already matches the same event across 15 or more venues through a free arbitrage API.
Conclusion
The honest answer to "Robinhood prediction markets API" is that there is not one. Robinhood ships exactly one public API and it is for crypto. Event contracts sit behind a broker relationship, a separate approved account and a mobile-only interface, which is a product decision rather than an oversight. The good news: what most people actually want, programmatic access to these markets, is available through the exchange underneath or an aggregator covering every venue at once.
One housekeeping note: this is information, not financial, tax or legal advice. Product availability, documentation, fees and state eligibility change and differ by person, so treat Robinhood's own help center and developer docs as binding and this page as a map.
