Kalshi vs Robinhood: Direct Exchange or Brokerage Routing?

By PredictQ Team // Updated: July 2026

For a year, “Kalshi vs Robinhood” was a trick question. Robinhood routed every event contract to Kalshi’s order book, so you were comparing Kalshi to Kalshi with a broker fee on top. That era ended June 4, 2026, when Rothera went live.

Rothera is the exchange Robinhood built with Susquehanna International Group: a joint venture (roughly 45% Robinhood, 45% Susquehanna, 10% MIAX) created by acquiring MIAXdx, a CFTC-licensed exchange and clearinghouse. World Cup and pro baseball contracts route there now, with more flow shifting over time. Robinhood also routes through KalshiEX and ForecastEx, so today it’s a broker with three venues behind it, not a skin on Kalshi.

The comparison finally has teeth. Here’s how it shakes out.

The Short Answer

Kalshi is still the better platform for anyone serious about prediction markets. Full catalog, transparent fees, a real welcome bonus, and direct exchange access. But Robinhood stopped being an easy dismissal. Its new pricing, live since June 1, 2026, caps commission at $0.01 per contract, half the old rate, and Gold subscribers pay up to 50% less than that. If you already run your financial life through Robinhood and trade casually, the convenience case is stronger than it has ever been.

Snapshot

1. Structure: Kalshi is a CFTC-regulated exchange and clearinghouse. Robinhood Derivatives is a CFTC-registered futures commission merchant routing orders to KalshiEX, ForecastEx, or Rothera.
2. Rothera: live since June 4, 2026. Independently managed JV with Susquehanna, CEO Thomas Chippas. Started with World Cup and pro baseball contracts.
3. Welcome bonus: Kalshi pays $10 for trading $10. Robinhood has no cash bonus for prediction markets; its June promo gave uncapped $0 commissions on World Cup trades for referring five friends.
4. Fees: Kalshi’s taker formula peaks at $1.75 per 100 contracts at 50 cents. Robinhood’s commission is probability-weighted and never exceeds $0.01 per contract, plus exchange fees on top.
5. Markets: Robinhood surfaces a curated mainstream slice. Kalshi runs the full catalog, including weather and climate markets Robinhood doesn’t carry.
6. Scale: Robinhood traded 12 billion-plus event contracts in 2025 and had already passed 16 billion in 2026 by early June. Prediction markets are its fastest-growing revenue line.

What Changed in June

Two things, and they both matter.

First, routing. Robinhood is no longer a pure Kalshi reseller. Rothera absorbed World Cup flow immediately, moving roughly $3 billion in volume during the tournament and taking around 7% of the US market in its first full month. Most non-World Cup flow still executes on Kalshi, but the direction is obvious: Robinhood wants its own rails.

Second, pricing. The old flat commission of about $0.02 per contract is gone. The new schedule varies by contract price and order size, drops near the price extremes, and caps at $0.01 per contract. Exchange fees are charged separately (Rothera’s is reportedly capped at another $0.01), and Robinhood Gold cuts the commission by up to half. On cheap longshots and deep favorites, Robinhood is now legitimately inexpensive.

Fees, Compared Honestly

Kalshi at the 50-cent peak costs $1.75 per 100 contracts to take, and a quarter of that for resting limit orders. Robinhood at $0.01 commission plus a capped exchange fee lands in a similar neighborhood on mid-priced contracts, sometimes better, sometimes worse depending on the venue fee. The gap that used to make this comparison a blowout has narrowed to a coin flip on many trades.

Where Kalshi still wins on cost: maker orders. Rest a limit order on Kalshi’s book and you pay 25% of the taker rate. Robinhood users can’t capture maker economics at all. Active traders should care about that a lot.

Markets and Interface

Robinhood shows you the hits: major sports, elections, econ prints, crypto prices. Kalshi gives you the whole catalog, hundreds of markets deep, including the niche categories where retail traders actually find edge. Nobody is out-researching a market maker on the NFL moneyline. Someone can absolutely out-research one on a county-level weather market.

The integration argument runs the other way. Robinhood puts event contracts next to your stocks, options, and crypto, funded from the same balance. One app, one login, no new account. For a casual trader that convenience is real.

State Availability

Not the clean “all 50 states” story it was in May. Kalshi’s sports contracts are blocked in Michigan under a June 30 court order and New York’s gaming regulator won the right to enforce state licensing rules on July 8. Robinhood’s sports contracts may also be unavailable in a small number of states. Non-sports categories are broadly available on both. Check eligibility in-app before funding.

Pick Kalshi If

• You trade enough volume that maker fees and full fee transparency matter.
• You want the complete market catalog, weather and climate included.
• You want the $10 welcome bonus; Robinhood has no cash equivalent.
• You’d rather trade on the exchange than through a broker in front of it.
• You don’t already use Robinhood. Opening a brokerage account just to reach markets Kalshi sells you directly makes no sense.

Pick Robinhood If

• You already keep money at Robinhood and want event contracts beside your stocks and crypto.
• You trade casually enough that a penny per contract is a rounding error.
• You’re a Gold subscriber; the commission discount stacks in your favor.
• You want exposure to Rothera-listed contracts like World Cup spreads and totals as they roll out.
• You value one app over the best possible execution.

Use Both?

Plenty of traders do. Claim Kalshi’s bonus, run your active trading there for the maker fees and catalog depth, and keep Robinhood for convenience trades inside the app you already open every day. There’s no conflict; for most markets they’re literally the same order book.

Bottom Line

Robinhood grew up. Rothera is live, the pricing is real, and the “Kalshi with a markup” line no longer describes the product. But grown up doesn’t mean better. Kalshi still offers more markets, cheaper economics for anyone using limit orders, and a bonus for showing up.
