Polymarket Hiring In-House Team to Trade Against Customers — Here's Why It's a Risk

The prediction market’s move toward internal market making could blur the line with sportsbooks and undermine the platform’s neutrality, experts warn.

What to know:

  • Polymarket is exploring an internal market-making team that would trade directly against users, a shift critics say resembles a traditional sportsbook rather than a prediction market.
  • Statistics professor Harry Crane argues the move offers limited revenue upside and significant PR, legal and trust risks, citing concerns over optics, potential data advantages and parallels to controversies at Kalshi and NoVig.
  • Observers worry the desk could erode Polymarket’s reputation as a market-driven probability gauge, a key factor in its prominence during the 2024 election cycle.

Prediction market Polymarket is in the process of hiring an internal market-making team that will trade directly against customers — a shift that could blur the lines between a prediction market and a traditional sportsbook.

The company has recently spoken to traders and sports bettors about building the new desk, according to Bloomberg, citing people familiar with the matter. The move follows a similar step by rival Kalshi, which has defended its own in-house trading team as a way to improve liquidity and the user experience.

In practice, however, hiring external market makers is entirely possible, raising questions about Polymarket’s true motivation. The decision appears focused less on product improvement and more on generating revenue.

“They don’t charge fees. They don’t make money. They want to find a way to monetize,” Harry Crane, a statistics professor at Rutgers University, told CoinDesk.

Crane said Polymarket plans to offer parlays through an RFQ protocol, with the in-house desk pricing and matching those bets.

“These require significant capital to back and also offer a substantial edge for the house if executed correctly,” he said. “I think it’s short-sighted and ultimately a mistake, but time will tell.”

A small revenue stream with outsized risks

Crane also questioned the financial logic behind the strategy.

“Given the huge valuations, it’s not a viable strategy to monetize, if that’s the objective,” he said. “Assuming the trading desk is profitable — which is far from a given — the amount it can profit is a pittance compared to its valuation.”

More importantly, Crane warned, the company can’t afford for the desk to be too profitable.

“The company should not want an in-house trading team to be too profitable, as that will create significant PR problems and possible legal issues,” he said. “Just look at the class-action against Kalshi for doing the same. That lawsuit appears to be 100% frivolous, but the optics and PR are not positive.”

Beyond the legal risks, Crane argued the move undermines Polymarket’s strategic identity. “This diminishes Polymarket's opportunity to differentiate itself from the competition, and it dedicates resources and focus to something that is definitively not what got the company to this point.”

A shift toward a sportsbook model

This change makes Polymarket resemble a sportsbook, where users effectively trade against the house rather than other bettors. At a sportsbook, in-house traders set prices and build in vigorish — typically giving the operator a 5%–10% edge.

Polymarket’s foray into this territory could create a conflict of interest and unsettle bettors who joined prediction markets precisely because they weren’t sportsbooks. Markets would no longer reflect the collective wisdom of traders but instead the pricing decisions of Polymarket’s internal desk.

It also risks eroding Polymarket’s reputation as a barometer of real-world probabilities. That reputation was a key engine of its rapid growth during the 2024 U.S. election cycle, when news outlets routinely cited Polymarket alongside polling data, boosting its mainstream legitimacy.

Blurring lines and raising questions

Crane said the sportsbook comparison understates the problem.

“Does it blur the line between a prediction market and a traditional sportsbook? Yes, but it's worse than that,” he said. “At a sportsbook it is well understood that the book is the counterparty, and will use whatever information it can to get the edge over its customers. Exchanges are supposed to be different.”

“But as long as there are in-house or privileged participants on an exchange, there will always be suspicions that they are gaining an unfair advantage,” Crane added, pointing to a recent controversy at NoVig, which voided a number of winning bets because its in-house market maker was the losing counterparty.

The introduction of an internal desk also raises operational and ethical questions reminiscent of the FTX-Alameda dynamic. How much order-flow or deposit-timing data will the desk have access to? Could it trade ahead of customer flows? Or will it simply post liquidity and collect spread, as some exchanges claim?

A risk to brand and trust

While market making may create a new revenue stream, the shift threatens the perceived neutrality and trust that helped Polymarket rise to prominence. The company did not immediately respond to CoinDesk’s request for comment.

Setting aside questions of fairness, Crane believes the strategy is simply misguided.

“It’s a bad business decision that takes a platform that previously felt very new and different and instead makes it look and feel just like everyone else,” he said.

Shibarium May No Longer Turbocharge Shiba Inu Price Rally, Here’s Reason

Shibarium May No Longer Turbocharge Shiba Inu Price Rally, Here’s Reason

The post Shibarium May No Longer Turbocharge Shiba Inu Price Rally, Here’s Reason appeared on BitcoinEthereumNews.com. Shibarium, the layer-2 blockchain of the Shiba Inu (SHIB) ecosystem, is battling to stay active. Shibarium has slipped from hitting transaction milestones to struggling to record any transactions on its platform, a development that could severely impact SHIB. Shibarium transactions crash from millions to near zero As per Shibariumscan data, the total daily transactions on Shibarium as of Sept. 16 stood at 11,600. This volume of transactions reflects how low the transaction count has dropped for the L2, whose daily average ranged between 3.5 million and 4 million last month. However, in the last week of August, daily transaction volume on Shibarium lost momentum, slipping from 1.3 million to 9,590 as of Aug. 28. This pattern has lingered for much of September, with the highest peak so far being on Sept. 5, when it posted 1.26 million transactions. The low user engagement has greatly affected the transaction count in recent days. In addition, the security breach over the weekend by malicious attackers on Shibarium has probably worsened issues. Although developer Kaal Dhairya reassured the community that the attack to steal millions of BONE tokens was successfully prevented, users’ confidence appears shaken. This has also impacted the price outlook for Shiba Inu, the ecosystem’s native token. Following reports of the malicious attack on Shibarium, SHIB dipped immediately into the red zone. Unlike on previous occasions where investors accumulated on the dip, market participants did not flock to Shiba Inu. Shiba Inu price struggles, can burn mechanism help? With the current near-zero crash in transaction volume for Shibarium, SHIB’s price cannot depend on it to support a rally. It might take a while to rebuild user confidence and for transactions to pick up again. In the meantime, Shiba Inu might have to rely on other means to boost prices from its low levels. This…

This Altcoin Could 1000x By 2026

This Altcoin Could 1000x By 2026

The post This Altcoin Could 1000x By 2026 appeared on BitcoinEthereumNews.com. The SEC has approved a framework for the streamlined adoption of digital asset products in the United States on Wednesday, allowing exchanges to list and trade commodity-based trust shares without requiring a rule change to be filed first. This marks a significant milestone, opening the door for a surge in spot altcoin ETFs in the coming months. As a result, anticipation is building around institutional liquidity flows to the altcoin market – but which projects could perform the best?  Many analysts are betting on Bitcoin Hyper (HYPER) as a potential 1000x opportunity. It has not yet launched on exchanges, so it’s not immediately eligible for a spot ETF like some of the larger altcoins. That said, its use case positions it at the forefront of blockchain innovation, which signals huge potential for price gains as institutional capital rotates through the altcoin market. The project is developing the world’s first ZK-rollup-powered Bitcoin Layer 2 blockchain, addressing Bitcoin’s key issues of slow speeds and limited functionality while maintaining its renowned characteristics of security and immutability. SEC Approves Generic ETF Listing Standards The SEC has approved a proposed 19b-4 rule change from Cboe’s BZX exchange, Nasdaq, and NYSE Arca to standardize listing requirements for crypto exchange-traded products (ETPs) and streamline the process for public trading. According to Bloomberg ETF expert James Seyffart, this move paves the way for a “wave of spot crypto ETP launches in the coming weeks and months.” WOW. The SEC has approved Generic Listing Standards for “Commodity Based Trust Shares” aka includes crypto ETPs. This is the crypto ETP framework we’ve been waiting for.
