Robinhood is quietly excluding some event contracts from its new prediction markets. This change comes amid concerns over insider trading and market manipulation.

Selective roll-out

Robinhood launched prediction markets in March 2025 through a partnership with Kalshi, aiming to let retail customers trade contracts that pay out if an event happens. But the broker isn't listing every contract available on the wider market. Instead, it's deliberately keeping certain questions off its platform while it builds the business out.

Robinhood’s choice reflects both caution and a clear business strategy.

People inside Robinhood have told journalists that the firm is excluding specific contracts because they're worried those markets would be unusually easy to manipulate. Platforms elsewhere have shown how fast prices can swing when a small group of traders has privileged information. The concern, as described by industry coverage, is that prediction markets often lack the same disclosure rules and surveillance that underpin public equity trading — and that gap creates room for bad actors.

Carley Olivas, Robinhood's senior director of brand strategy and operations, has been clear that the company's sports partnerships — its NASCAR and NBA sponsorships, for example — aren't meant to drive users into prediction markets. She framed those deals as efforts to build brand awareness among engaged fan communities while treating prediction markets as a separate offering that the company will expand carefully.

Why manipulation worries them

Prediction markets reward information. They can also reward secrecy. If someone knows about a corporate deal, a withheld medical result, or an internal political decision, they could trade a contract tied to that outcome and profit before the information becomes public. That's insider trading in spirit, if not always by the letter of securities law.

Thing is, current enforcement focuses on established securities and derivatives. The Commodity Futures Trading Commission has authority over some event contracts, but regulatory lines remain fuzzy. That patchwork leaves room for weaker oversight on many prediction-market products — and platforms hosting those products face reputational risk if users start to suspect markets reflect private tips rather than collective judgment.

Robinhood's caution reflects a broader industry wake-up call. Over the past couple of years, other platforms such as Polymarket, Kalshi and PredictIt attracted billions in bets on everything from elections to central-bank moves. But several of those venues have also been the subject of regulatory scrutiny and legal disputes, underscoring the risks that come with rapid growth.

Several reporters who spoke to company officials said Robinhood is ‘very focused on insider trading’ as it expands the feature set — which helps explain why it's leaving some contracts off its homepage even as it promotes a slate of sports and finance-related outcomes.

Mastheads

Regulatory fight is heating up

Robinhood is also taking that regulatory fight to court. The firm sued Washington state on 30 March 2026 after state regulators moved to block event-based contracts there, arguing those products resemble gambling under local law. The lawsuit names the state attorney general and the Washington State Gambling Commission as defendants, and it asks a federal court to rule that federal regulation of derivatives takes precedence.

At present, courts have issued differing rulings. Earlier this month the US Court of Appeals for the Third Circuit issued a ruling finding that the Commodity Exchange Act can pre-empt state gambling laws for some event contracts — a decision that bolsters the position that certain prediction markets belong under federal, not state, oversight.

Robinhood's legal argument mirrors that line of thinking: treat event contracts as derivatives, and bring them within the Commodity Futures Trading Commission's remit. That would create a uniform federal framework for some sorts of prediction-market trading, rather than a patchwork of state rules that vary widely.

Jamie Dimon, JPMorgan Chase CEO, has publicly suggested his bank might explore prediction-market-style services — an indication that large incumbents are watching how the legal fights play out and considering entry. If big banks decide to offer similar products under CFTC rules, the market could look very different than the current crypto-native or boutique-platform ecosystem.

Business calculus

Robinhood's selective listing makes business sense, even if it reduces near-term turnover. The company has spent years trying to rebuild trust since the meme-stock episodes of 2021 and a string of regulatory headaches. Any hint that its markets are subject to insider flows would be damaging.

Robinhood is taking a more measured approach. By excluding contracts that seem especially exposed to manipulation, it limits short-term revenue but protects its brand and reduces legal exposure while the regulatory picture clarifies.

This strategy also influences how they design their products. Exchanges and established derivatives venues operate with surveillance tools, position limits and reporting obligations that help catch suspicious trades. Retail-focused apps have to decide whether to adopt similar rules, to partner with regulated clearinghouses, or to keep their offerings deliberately narrow.

Robinhood's partnership with Kalshi gives it one compliance route: offer event contracts through a firm that already operates inside aspects of the current federal framework. But even with that tie-up, Robinhood still faces local legal challenges and the practical problem of policing markets where the information edge can be subtle and fast-moving.

What it means for users

For retail traders, the immediate effect is limited choice. Some wagers that appear elsewhere won't be available on Robinhood. That could disappoint a subset of users who want to speculate on a wide set of political, corporate or sporting outcomes.

But there's another side: users may get greater confidence that listed contracts are less likely to be tainted by insiders. If Robinhood's exclusions reduce the perception of unfairness, that could attract traders who now avoid prediction markets because of manipulation worries.

Still, the bigger question is legal: will federal regulators and courts create a clear, consistent rulebook for these products? If they do, platforms will either adapt to tighter rules or move out of the market. If they don't, expect continued fragmentation — some states banning parts of the market, others allowing it under various conditions.

Robinhood is betting that the right mix of selective product choices, partnerships and legal pressure will let it keep a foothold without exposing the business to unnecessary harm.
