Polydelve

Polydelve is a prediction market focused on open-source security — you take positions on questions like whether a given package (e.g. on PyPI) will get a high-severity CVE or an EPSS spike within a window, with multiplier payouts and a leaderboard turning collective forecasting into a signal.

It targets security researchers, maintainers and developers who want a market-driven early read on which open-source components are likely to become risky.
