Co-founded by CEO Oscar Levy and CTO Antonin Parrot, River Markets offers software, data links, risk-management tools and algorithms that let professional traders trade across disparate prediction-market venues. The founders began building trading software while working full time in quantitative and electronic trading roles and turned that technology into an enterprise platform after the tool generated seven-figure trading profits. River Markets launched its platform in May and says it is on track to exceed hundreds of millions of dollars in annualized trading volume by year-end. The company plans to use its seed funding to hire engineers, build faster and more secure systems, and expand sales and operations as it signs professional clients. The product targets institutional needs such as handling larger orders, limiting price swings from big trades, and enabling cross-platform execution.
