About CatalystAlert
Every biotech catalyst, confidence-rated and sourced — and an email when a date you watch moves.
Our Mission
CatalystAlert tracks biotech catalysts — FDA decisions (PDUFA dates), AdCom meetings and clinical-trial readouts — for 1,200+ biotech and pharma stocks. Every catalyst date carries a confidence rating (confirmed against an official source, estimated, or AI-detected) and links to its source; resolved events keep their outcome and stock move, and the models behind its AI research publish a scored track record.
CatalystAlert was built to democratize access to biotech catalyst intelligence — combining official regulatory data with machine learning to help investors track market-moving events.
Biotech is complex: FDA decisions, clinical-trial readouts, and PDUFA dates can move a stock sharply in a single day. We track these catalysts, label how reliable each date is, and publish our prediction track record openly — so you can judge the signal for yourself.
