Prop Firm Jump Trading to Take Stakes in Kalshi and Polymarket: Report

Monday, 09/02/2026 | 21:02 GMT by Jared Kirui
  • Both prediction markets depend on market makers to supply capital and maintain orderly.
  • Other trading companies, such as Susquehanna International Group and Robinhood, have made similar moves.
Jump Trading

Jump Trading is set to gain small stakes in prediction-market platforms Kalshi Inc. and Polymarket in return for providing liquidity, according Bloomberg. The move tightens the Chicago-based firm’s ties to a fast-growing corner of derivatives trading built around event-based contracts.

Venture-Style Liquidity Deals

Jump’s agreement with Kalshi involves a set amount of equity in the company, the people said, who asked not to be identified because the talks are private. The size of its stake in Polymarket will depend on how much trading capacity Jump ultimately provides to the platform’s US operation.

The arrangements resemble venture deals, with Jump receiving ownership in exchange for supplying liquidity and trading resources rather than only cash.

Kalshi and Polymarket rely on market makers, including in-house systems, that commit capital and stand on the other side of client trades. These firms help keep markets open and prices tight, particularly during volatile or uncertain periods.

Kalshi’s latest funding round valued the platform at about 11 billion dollars, while Polymarket’s recent fundraising put its valuation near 9 billion dollars.

Expansion of Event-Contract Trading

The investments align with Jump’s broader push beyond traditional asset classes such as equities into event-based contracts. The firm, founded in 1999 by two former Chicago Mercantile Exchange pit traders, already trades US Treasuries, futures and crypto, using quantitative strategies driven by artificial intelligence models.

Other trading firms have taken similar steps. Susquehanna International Group disclosed in 2024 that it would act as a market maker on Kalshi. Last year, Susquehanna and retail brokerage Robinhood Markets Inc. acquired a majority stake in LedgerX, a US-based derivatives exchange.

That deal gave them direct control over infrastructure to list and clear event contracts, with Susquehanna serving as a “day-one liquidity provider” to ensure customers have a ready counterparty.

Late last year, Jump Trading started making markets on Kalshi, marking one of the first instances of a major proprietary trading firm entering the fast-emerging event-betting sector attracting attention across Wall Street and Silicon Valley. The firm then started providing liquidity on Kalshi’s event contracts.

    Brendan Callan joined us fresh off the Summit’s most anticipated debate: “Is Prop Trading Good for the Industry?” Brendan argued against the motion — and the audience voted him the winner. In this interview, Brendan explains the reasoning behind his position. He walks through the message he believes many firms avoid: that the current prop trading model is too dependent on fees, too loose on risk, and too confusing for retail audiences. We discuss why he thinks the model grew fast, why it may run into walls, and what he believes is needed for a cleaner, more responsible version of prop trading. This is Brendan at his frankest — sharp, grounded, and very clear about what changes are overdue.
