Bullfrog AI Holdings jumps 55.24% after-hours amid AI-driven cybersecurity and application software momentum.

Bullfrog AI Holdings surged 55.24% in after-hours trading, following a 57.16% intraday rally to $1.6502 on March 31, 2026, driven by a 1183% spike in turnover and a broader narrative of AI-driven cybersecurity and application software advancements. Although no company-specific news was released, recent sector-wide AI-related developments—including AI-powered conferencing tools, enterprise software, and cyber threats—fueled speculative buying. The stock's sharp intraday move and continued after-hours momentum suggest strong retail and institutional interest in the AI growth story, despite muted performance from sector peers like Salesforce.
