Robinhood want more in Prediction Markets

News Roundup: Robinhood want more contracts, regulation heats up, app data shows sportsbook users are switching, FT investigation finds a $9M Polymarket account nobody will claim. Plus, everything else in prediction markets this week.

Robinhood are in talks to add Crypto[dot]com's prediction markets alongside what they already offer, as they look to make a real mark in prediction markets.

Robinhood already have a venue. They built Rothera with Susquehanna. Adding a second exchange's markets on top means routing customers across more than one venue, the way a broker would.

🧠 Opinion: I don't really get why this makes much sense for Crypto[dot]com. They're basically letting their contract inventory be rented by Robinhood, who get to use it as a way to validate demand from retail. And then eventually just self-certify the contracts themselves, and cut out Crypto[dot]com. Maybe I’m being too cynical, and everyone will continue being friendly in this arena!

2. Big Week for Regulators

Washington became the fourth state to block Kalshi's sports contracts, Wisconsin threatened election traders with losing their vote, and the CFTC warned operators over blanket self-certifications, all in the same week.

Washington blocks the sports contracts. On 21 July, King County Superior Court Judge John McHale granted Washington a preliminary injunction against Kalshi's sports contracts, ruling the platform was likely running an unlicensed gambling operation. The ruling rejected Kalshi's central defence: that the Commodity Exchange Act, a federal law, overrides state gambling rules. That is the same argument a New York judge rejected two weeks ago, and the same one Kalshi have now lost in four states: New York, Michigan, Nevada and Washington.

Wisconsin goes after the traders instead. The Wisconsin Elections Commission told voters that trading an election market could cost them the right to vote in it. Their lawyers pointed to a state law disqualifying anyone who has "made or become interested, directly or indirectly, in any bet or wager depending upon the result of the election". Kalshi called it voter suppression.

And the CFTC warned on self-certification. In an advisory on 24 July, staff at the federal regulator said operators have been self-certifying "broad, template event contracts" that bundle many permutations, with different settlement sources and methods, under a single certification. The submissions often skip the terms for each version, which limits the agency's ability to check settlement rules, data sources and manipulation controls. It is the second such warning this year.

Prediction markets took 27% of US sports betting during the World Cup.

In the first half of June, Kalshi and Polymarket took nearly three-quarters of all new installs across the major betting and prediction apps: Kalshi 42.3%, Polymarket 31.2%, against DraftKings on 13.7% and FanDuel on 8.9%.

An FT investigation found that a Polymarket account in the name of George Cottrell, the financier and convicted fraudster close to Nigel Farage, received roughly $8.8 million in crypto from unidentified sources in October 2024.

The money arrived in tranches: about $7 million from OKX across five transfers, another $1.83 million routed through ChangeNOW. It went on Donald Trump winning the presidency. The position returned $4.46 million in profit, and shortly after the result, the account was emptied into two more wallets.

Who put the money in, and who took the winnings out, remains unknown. Cottrell declined to say who beneficially owned the wallet, or whether any of it supported Farage or Reform UK.

FanDuel's route into prediction markets runs through CME Group. That partnership is now visibly awkward, because CME's chief executive Terry Duffy has been publicly calling some sports prediction markets gambling. And FanDuel are, of course… a gambling company.

CME are a 175-year-old derivatives institution whose reputation rests on not being a casino. So it’s not surprising they’re following a lot of financial services leaders in being sports contract detractors, or at the very least, not wanting to take part in them.
