Open Source Quantitative Finance

The annual Open Source Quantitative Finance conference (osQF, formerly R/Finance) will be held on Friday & Saturday, October 23rd-24th, 2026, at the University of Illinois Chicago. The conference focuses on applied finance using open source programming languages and free software systems for statistical computation and graphics.

The 1.3 day conference will cover topics including AI, advanced risk tools, decentralized finance, econometrics, high-performance computing, market microstructure, portfolio management, and time series analysis. All will be discussed within the context of using open source programming languages as primary tools for financial model development, portfolio construction, risk management, and trading.

Over the years, the conference formerly known as R/Finance has included work contributed in many open source programming languages. We expect to welcome attendees from around the world and host presentations from prominent academics and practitioners. We look forward to an exciting lineup for 2026!

Once again, we are planning to partner with PyData Chicago to kick off the conference on the evening of Thursday, October 22nd. A series of relevant talks on quantitative finance will be presented, followed by an opportunity to sample Chicago’s vibrant nightlife.

The osQF 2026 Call For Presentations is open!

If you work at the intersection of open source and finance, we want to hear from you. Submissions are accepted on a rolling basis and are due by Friday, July 24th, 2026.
