Jump Trading Inc., a Chicago-based firm specializing in algorithmic and high-frequency strategies, has reached an agreement to acquire a small stake in prediction market operators Calci Inc. and Polymarket Inc., Bloomberg reported Monday, citing people familiar with the deal.
The investment further deepens the proprietary trading giant’s exposure to event-based wagering as it begins offering market-making liquidity on its Karshi platform.
As reported, the deal with Calsi will give Jump a specified number of shares, while the company’s stake in Polymarket will grow over time depending on the level of trading capacity that Jump contributes in the United States.
Calci, a CFTC-regulated venue for deal agreements with real-world consequences, secured $1 billion in funding in November 2025 at a valuation of $11 billion. Sequoia and Andreessen Horowitz participated in this round.
Polymarket is a blockchain-based platform that provides permissionless access to performance-driven contracts and was estimated to be worth $12 billion to $15 billion during the same period.
Jump’s interest in gambling platforms predates its involvement in the cryptocurrency market. The company operated a dedicated sports betting unit at Betfair until it was discontinued in 2023, and backed sports trading through its venture arm, Jump Capital.
Other major trading companies are also entering this field. Susquehanna International Group currently provides liquidity to the Karshi Exchange.
Coinbase is separately working on building a predictive product using Karshi’s infrastructure, demonstrating the growing convergence between traditional trading companies and crypto-native platforms in the event contract space.
