Figma Inc. (FIG) has surged 45% in just six trading days, fueled by excitement over its deep integration with OpenAI’s ChatGPT, unveiled during Sam Altman’s DevDay presentation. The feature allows users to create diagrams directly through ChatGPT commands, marking Figma as one of the first major creative tools embedded in OpenAI’s new Apps SDK.

The stock’s explosive rally included a 17% jump Wednesday, its strongest three-day run since its IPO in July. Analysts are calling it “the OpenAI effect,” as the collaboration could channel millions of new users from ChatGPT into Figma’s ecosystem.

Following a 65% post-IPO decline, the rally revives investor optimism that Figma could evolve from a design app to a core AI-driven creative infrastructure platform. Still, sustainability of the rally depends on user adoption metrics in the coming quarters.
