Meet Rothera: Robinhood's Challenger to Kalshi and Polymarket

As if the battle for supremacy between Kalshi and Polymarket in the prediction markets wasn't interesting enough, Robinhood has just inserted itself into the conversation once again. This time, however, it did so by forging a dynamic new partnership with CFTC-regulated prediction market exchange Rothera. 

Timed to perfection ahead of the FIFA World Cup, June's launch saw the platform register over $2B in trades, immediately capturing 7% of the US prediction market volume. With some of the most influential figures in the industry in its wheelhouse, Rothera looks set to bolster Robinhood's weaponry to take on the likes of both Kalshi and Polymarket across the entire prediction market space.

The World Cup Marks the Biggest Prediction Market Event in History

Straight up, the timing of Rothera's entry into the prediction market war was no coincidence - put simply, as the biggest single-sport betting spectacle on the planet, the FIFA World Cup's kickoff in June was the ideal place to start. 

Although the magnitude of their success would certainly have surpassed all expectations of those involved, it has also ruffled Polymarket and Kalshi's feathers at the same time. Sure, the aforementioned incumbents had a sizable head start on the World Cup prediction markets, but 7% of the market is a sizable chunk for Rothera to have bitten off on its debut.

Fortunately, with FIFA expanding the tournament to a new 48-team format, with 104 matches set to be played in 39 days, there were plenty of markets to choose from. Outside of the individual match markets, Polymarket and Kalshi alone have registered record-breaking amounts of trading volume on their marquee event contracts, including:

So Who Is Rothera and Why Are They Instantly Making Waves?

For starters, unlike many industry newcomers, Rothera was deliberately built with institutional-grade infrastructure right from the outset. Already primed as a fully CFTC-regulated Designated Contract Market (DCM) and Derivatives Clearing Organization (DCO), this gave it the green light to list and clear event contracts under US federal oversight.

Launching in Chicago in 2025, the firm set out to become the go-to regulated prediction market exchange that would handle trades for everyone, from leading Wall Street firms to your everyday sports betting enthusiasts.

Now, while that may have seemed like a bold ambition, it did so for good reason - that being that Rothera is actually a joint venture between early-prediction market pioneers Robinhood and Susquehanna International Group, one of the world's largest quantitative trading firms. 

As a result, rather than having to rely on outside exchanges such as Kalshi, Robinhood can now route all of its prediction market trades and sports event contracts directly through Rothera. For the enterprise itself, the benefits include a new ultra-efficient in-house trading system, with improved liquidity, while also drastically cutting its overheads in the process.

Why Sports Bettors and Traders Should Be Paying Attention

As Robinhood and Rothera's flagship launch event, it's easy to see why they had their sights set on the 2026 FIFA World Cup from the jump. The reason being, not only does soccer's grandest event take place every four years - significantly amplifying engagement levels among sports fans and bettors - but the expansion to now include 48 nations elevated the platform's appeal to an even greater global consumer base.

Another key element to the World Cup is the sheer volume of event markets that can be offered - completely unrivaled in comparison to any other single-sports-based tournament in the world. These included tournament-based team and player event contracts, as well as the individual game-specific markets for all 104 World Cup matches, such as: 

• World Cup Winners
• Group Winners
• World Cup Golden Boot
• World Cup Golden Ball
• Stage of elimination 
• Total Goals
• Player to Score First
• New Nation to Win the World Cup 

As you can see, the World Cup variety of options is seemingly endless, and as the record-breaking trade volumes and liquidity can already attest to, sports bettors have eagerly jumped ship from wagering on traditional sportsbooks in favor of sports-driven prediction markets.

Rothera is Built for the Long Game, Not Just the World Cup

It's not just soccer bettors that should be excited, as the World Cup is just the beginning of the Rothera/ Robinhood vision, having also launched contracts covering US professional baseball. Plans are also afoot to expand further into additional sports, including the upcoming NFL season, as well as more conventional trading markets, including cryptocurrencies, geopolitical events, and even democratic elections, as regulatory approvals allow. 

Rothera’s DNA is as fascinating as its prediction market benefits, with a genuine who's who heading up the leadership team that instinctively pairs with Robinhood's preexisting commercial footprint and Susquehanna's formidable liquidity.

Here, Rothera CEO Thomas Chippas was formerly CEO of Argo Blockchain and ErisX, while President Matt Trudeau is credited with launching more than a dozen trading venues during his illustrious career, which included leadership roles at Cboe Digital, IEX, Instinet, and Chi-X. 

Undoubtedly built by industry titans with decades of experience constructing regulated financial marketplaces, Rothera can facilitate 24/7 trading across its portfolio of product lines. It does so using a high-speed matching engine, backed by fully funded clearing rails and segregated customer funds, designed to complement Robinhood's promise that commissions will never exceed $0.01 per contract.

The Bottom Line

As a punter, it’s hard to escape the allure of prediction markets like Robinhood, Polymarket, and Kalshi’s disruptive nature within the sports betting ecosystem. Simply reducing the inherent sportsbook overrounds with the added incentive of the ever-popular trading style approach, it’s not hard to see why it has already siphoned billions away from traditional operators' bottom lines. 

In the case of Rothera and Robinhood, its immediate success during the World Cup was the perfect precursor for things to come. Given it has all the ingredients - a combination of federal regulation, institutional-grade infrastructure, Robinhood integration, and super competitive fees - if the impressive early trading volumes are anything to go by, the groundbreaking partnership has the foundations to mount a serious challenge to be top dog in the prediction market sector.
