Jump Trading takes stakes in Kalshi and Polymarket for market-making

Equity tied to market-making

Jump Trading is set to receive equity stakes in Kalshi and Polymarket through market-making arrangements, according to Bloomberg reporting summarized by gamblerss.com.

The proprietary trading firm’s Kalshi arrangement provides for a fixed equity stake. The available summary does not specify its size.

At Polymarket, Jump Trading’s stake could increase if capacity targets are met, Bloomberg reports. The summary does not identify those targets or say how much additional equity could be awarded.

The distinction is in how the ownership interests are structured: Kalshi’s stake is fixed, while Polymarket’s includes a conditional path to a larger holding. The underlying article text was unavailable, limiting the details that can be established from the report.

What it means for prediction markets

• Market-making is central to the arrangements. For prediction-market readers, the report concerns the platforms’ trading infrastructure rather than the outlook for any particular event contract.
• Polymarket’s capacity targets are a key unknown. Their definition would help readers assess what Jump Trading must deliver to expand its stake.
• Trading effects remain unestablished. The available summary provides no measures of liquidity, spreads or execution quality, so it does not support conclusions about how the arrangements will affect users.
