One prediction market prices this story:
- Yes — the market puts it at 21%, closing 1 Dec 2026. The market resolves to Yes if CISA issues an Emergency Directive targeting specific PHP vulnerabilities before December 1, 2026. Otherwise, it resolves to No. Readers often mistake general security alerts for the required Emergency Directive.
Odds are the market's probability that the outcome happens, updated every few minutes. They are information about what traders expect, not a forecast we make and not investment advice.
How it unfolded
Every source in the order it published, with the odds on Yes at that moment. A dash means the source published before we started tracking prices.
