Polymarket is expanding its internal operations as the prediction platform prepares for a new phase of growth driven by rising user activity.
The company is assembling an in-house group of traders and market makers, a move intended to strengthen liquidity and reduce its dependence on high-volume whales that have historically dominated trading flows.
The decision follows Polymarket’s record activity in November, where trading volumes and open interest surged, attracting increased attention from professional traders and industry observers.
Platform Seeks Greater Liquidity And Stability
For years, Polymarket’s markets relied heavily on large individual holders who shaped the odds through outsized positions.
This structure helped sustain volume but also led to concerns about imbalance, particularly in thinly traded markets where a single whale could shift prices significantly.
By adding an in-house team, Polymarket aims to create more reliable liquidity conditions while helping ensure that even niche markets remain tradable.
Reports indicate that the new market makers may also trade directly against users, a practice that has sparked debate within prediction-market circles.
Internal Market Makers Spark Scrutiny
The use of internal market makers has long been controversial in the prediction-market community.
Critics argue that platform-backed traders could influence market outcomes or introduce bias into probability estimates that are supposed to be fully user-driven.
Those concerns resurfaced as rumors spread of Wintermute and other established crypto trading firms potentially participating in Polymarket markets.
Community members have also identified wallets linked to Wintermute activity on the platform, fueling speculation that professional firms already play a significant role behind the scenes.
Professional Traders Drawn To Expanding Markets
The sharp rise in activity through 2024 and 2025 has transformed Polymarket into a highly specialized ecosystem where competitive traders pursue arbitrage opportunities, real-time information advantages, and niche expertise.
Bloomberg reported that Polymarket reached out to professional traders — including individuals with backgrounds in sports betting — as part of its hiring push, according to unnamed sources.
The move signals the platform’s shift from a retail-driven experimental project into a more structured financial marketplace.
Balancing Neutrality And Growth
Traditional prediction platforms like Kalshi rely heavily on in-house teams that actively trade against users to balance markets, a model closer to traditional sportsbooks.
Polymarket, by comparison, built its reputation on a decentralized, user-driven approach where probabilities emerged organically from crowd input rather than internal pricing.
As Polymarket prepares for a U.S. expansion — including a closed beta launch of its iOS app — the introduction of internal market makers presents both strategic advantages and reputational risk.
Supporters argue that market makers help sustain orderly trading and ensure less popular markets remain functional.
Skeptics warn that too much internal involvement could undermine Polymarket’s core value proposition as a marketplace of distributed knowledge.
Strong Momentum Heading Into 2025
Polymarket’s open interest recently climbed above $286 million, marking one of its strongest multi-month growth periods since late 2024.
The platform has not yet surpassed its previous open-interest record but is trending toward new highs if user participation continues at the current pace.
With a growing U.S. presence, an evolving internal team, and increasing institutional interest, Polymarket enters 2025 positioned for rapid expansion — while facing heightened expectations around fairness and transparency.
