Prediction market Polymarket is within the means of hiring an inside market-making group that may commerce straight towards prospects — a shift that might blur the traces between a prediction market and a conventional sportsbook.
The corporate has not too long ago spoken to merchants and sports activities bettors about constructing the brand new desk, based on Bloomberg, citing individuals aware of the matter. The transfer follows an identical step by rival Kalshi, which has defended its personal in-house buying and selling group as a manner to enhance liquidity and the person expertise.
In follow, nonetheless, hiring exterior market makers is fully doable, elevating questions on Polymarket’s true motivation. The choice seems centered much less on product enchancment and extra on producing income.
“They don’t cost charges. They don’t become profitable. They wish to discover a technique to monetize,” Harry Crane, a statistics professor at Rutgers College, advised CoinDesk.
Crane stated Polymarket plans to supply parlays via an RFQ protocol, with the in-house desk pricing and matching these bets.
“These require vital capital to again and likewise provide a considerable edge for the home if executed appropriately,” he stated. “I believe it’s short-sighted and finally a mistake, however time will inform.”
A small income stream with outsized dangers
Crane additionally questioned the monetary logic behind the technique.
“Given the massive valuations, it’s not a viable technique to monetize, if that’s the target,” he stated. “Assuming the buying and selling desk is worthwhile — which is much from a given — the quantity it might probably revenue is a pittance in comparison with its valuation.”
Extra importantly, Crane warned, the corporate can’t afford for the desk to be too worthwhile.
“The corporate shouldn’t need an in-house buying and selling group to be too worthwhile, as that may create vital PR issues and doable authorized points,” he stated. “Simply take a look at the class-action towards Kalshi for doing the identical. That lawsuit seems to be 100% frivolous, however the optics and PR will not be optimistic.”
Past the authorized dangers, Crane argued the transfer undermines Polymarket’s strategic identification. “This diminishes Polymarket’s alternative to distinguish itself from the competitors, and it dedicates assets and focus to one thing that’s definitively not what bought the corporate so far.”
A shift towards a sportsbook mannequin
This alteration makes Polymarket resemble a sportsbook, the place customers successfully commerce towards the home slightly than different bettors. At a sportsbook, in-house merchants set costs and construct in vigorish — sometimes giving the operator a 5%–10% edge.
Polymarket’s foray into this territory might create a battle of curiosity and unsettle bettors who joined prediction markets exactly as a result of they weren’t sportsbooks. Markets would not replicate the collective knowledge of merchants however as a substitute the pricing choices of Polymarket’s inside desk.
It additionally dangers eroding Polymarket’s popularity as a barometer of real-world possibilities. That popularity was a key engine of its speedy progress through the 2024 U.S. election cycle, when information retailers routinely cited Polymarket alongside polling information, boosting its mainstream legitimacy.
Blurring traces and elevating questions
Crane stated the sportsbook comparability understates the issue.
“Does it blur the road between a prediction market and a conventional sportsbook? Sure, however it’s worse than that,” he stated. “At a sportsbook it’s effectively understood that the e-book is the counterparty, and can use no matter data it might probably to get the sting over its prospects. Exchanges are presupposed to be completely different.”
“However so long as there are in-house or privileged members on an alternate, there’ll all the time be suspicions that they’re gaining an unfair benefit,” Crane added, pointing to a current controversy at NoVig, which voided a lot of profitable bets as a result of its in-house market maker was the dropping counterparty.
The introduction of an inside desk additionally raises operational and moral questions harking back to the FTX-Alameda dynamic. How a lot order-flow or deposit-timing information will the desk have entry to? May it commerce forward of buyer flows? Or will it merely put up liquidity and accumulate unfold, as some exchanges declare?
A danger to model and belief
Whereas market making might create a brand new income stream, the shift threatens the perceived neutrality and belief that helped Polymarket rise to prominence. The corporate didn’t instantly reply to CoinDesk’s request for remark.
Setting apart questions of equity, Crane believes the technique is solely misguided.
“It’s a nasty enterprise resolution that takes a platform that beforehand felt very new and completely different and as a substitute makes it feel and look similar to everybody else,” he stated.
