Best prediction markets platforms for US investors (compared in 2026)

Plus500 Futures launched its prediction markets offering in early February 2026, making it one of the newest entrants in the space, but it’s backed by serious infrastructure. The platform provides access to Kalshi’s CFTC-regulated event contracts, while Plus500 handles clearing through its membership with Kalshi Klear LLC.

What makes Plus500 our top pick is its positioning as a proper broker for prediction markets. If you’re already comfortable with futures trading or traditional brokerage platforms, Plus500 Futures will feel immediately familiar. You can trade event contracts on economic, financial, and geopolitical events, all within the same app where you’d trade E-mini S&P 500 futures or crude oil contracts.

The $0.01 per contract commission is competitive and transparent. There are no deposit fees on the broker side (though your bank may charge separately), and the demo account lets you explore the entire platform risk-free with virtual funds.

Plus500 is also the clearing partner for CME Group and FanDuel’s event-based contracts platform, which signals strong institutional credibility. As an FTSE 250 publicly listed company with over 33+ million registered customers with the Plus500 Group since inception, the corporate backing here is unmatched by most prediction market startups.

The main limitation is that Plus500 is essentially a front-end for Kalshi’s order book, so your liquidity and market selection depend on what Kalshi offers. But for US investors who want a clean, regulated, broker-style experience for prediction markets alongside traditional futures, Plus500 is the best option available today.

For a deep dive, please read our Plus500 Futures review.

Kalshi is the backbone of US prediction markets. As the first CFTC-designated contract market for event contracts, it provides the regulatory infrastructure that many other platforms (including Plus500 and Robinhood) rely on to offer their own prediction market products.

If you want direct access to the exchange with the broadest market selection, Kalshi is the natural choice. Its event contracts cover everything from Federal Reserve rate decisions and CPI data releases to Super Bowl outcomes, Oscar winners, and even hurricane forecasts. The platform generated $263.5 million in fee revenue in 2025 and was valued at $11 billion following its Series E round, making it one of the most well-capitalized fintech companies in the prediction space.

The fee structure is worth understanding: rather than a flat rate, Kalshi charges based on the contract price. Contracts priced around 50 cents carry the highest fees, while those near 1 cent or 99 cents are significantly cheaper. Free ACH deposits help keep costs down, though the 2% debit card fee is a drawback.

The reason Kalshi ranks second rather than first is that for most traditional investors, the broker-style experience of Plus500 Futures will feel more natural. However, Kalshi remains the best option for traders who want direct exchange access, the widest market coverage, and full order book control.

Robinhood entered prediction markets in October 2024 with presidential election contracts and has since expanded aggressively. Its prediction market hub now features over 1,600 active markets, and event contracts have become the platform’s fastest-growing new product, with 8.5 billion contracts traded in Q4 2025 alone.

The biggest advantage of Robinhood is convenience. If you already trade stocks, ETFs, or crypto on the platform, prediction markets feel like a natural extension of your portfolio. You can fund trades from the same account, and the interface makes it easy to browse markets by category.

The custom combo feature is unique: you can package up to 10 individual event contracts into a single multi-leg position, similar to parlay bets but structured as regulated financial contracts. This is something neither Kalshi nor Plus500 currently offer.

The downside is cost. Robinhood adds its own commission layer on top of Kalshi’s exchange fees, which means you’ll pay more per trade than going directly through Kalshi or Plus500. For active traders, this cost difference adds up significantly.

Polymarket is the undisputed global volume leader in prediction markets, processing billions in trading volume monthly. The platform’s liquidity is unmatched – even multi-million dollar trades experience minimal slippage on major markets.

The zero-fee structure on most markets is a massive advantage for active traders. While some newer categories carry taker fees, the majority of Polymarket’s markets remain fee-free, making it the cheapest platform for high-volume trading.

The catch for US investors is access. Polymarket acquired QCEX (a CFTC-licensed exchange) in late 2025 and is gradually rolling out US access to waitlisted users, starting with sports markets. You’ll need a crypto wallet and USDC to participate, which adds friction for investors who prefer traditional banking.

For US investors who are comfortable with crypto and can access the platform, Polymarket offers the best combination of liquidity and low costs in the prediction market space.

FanDuel Predicts launched in December 2025 as a standalone app, backed by a partnership between Flutter Entertainment (FanDuel’s parent company) and CME Group, the world’s largest derivatives marketplace. Flutter plans to invest $200-$300 million into the prediction market product in 2026.

The platform is designed to give fans in non-betting states a legal way to engage with sports outcomes through regulated event contracts. Phase one covers sports, finance, economics, and politics, with phase two expected to add crypto, stocks, pop culture, and more.

For sports-focused traders, particularly those in states where traditional sports betting is illegal, FanDuel Predicts offers a compelling alternative. The clearing infrastructure is handled by Plus500, adding institutional credibility. However, the platform is still early in its rollout.

DraftKings launched its Predictions product in December 2025 across 38 states. The platform is particularly interesting because DraftKings acquired Railbird, an event contract exchange, and plans to roll out its Railbird-powered proprietary exchange later in 2026.

For now, DraftKings Predictions serves primarily as a complement to its daily fantasy sports platform. The market selection is narrower than Kalshi or Polymarket, and the company did not include prediction market revenue in its fiscal 2026 guidance, suggesting the product is still in an early growth phase.

PredictIt is the grandfather of US prediction markets. After years of legal battles with the CFTC, the platform won its lawsuit in July 2025 and received full regulatory approval in September 2025. For pure political forecasting, PredictIt offers unmatched depth – from presidential and congressional races to cabinet appointments and niche policy outcomes.

The main drawback is cost. The 10% profit fee plus 5% withdrawal fee means you need roughly 16% gross returns just to break even after cashing out, making it the most expensive prediction market in the US. The $3,500 position limit also restricts serious capital deployment.

PredictIt is best suited for political junkies and policy researchers who value depth in down-ballot political markets over breadth across other categories.
