OpenAI lit the fuse, but the AI hype train shows no signs of slowing down. After an AMDAMD

deal surged the chipmaker’s shares by 23.7% on Monday, fresh partnership announcements are fueling billion-dollar gains across travel, tech, and retail. It’s no longer just the “OpenAI effect” — markets are jumping on any AI name drop.

• FigmaFIG
  popped 7.4% after OpenAI unveiled its “talking to apps” feature — which connects users to services like ExpediaEXPE
  , SpotifySPOT
  , and others without leaving ChatGPT.
• Even OpenAI rival Anthropic is shaking markets — bumping IBMIBM
  as much as 4% yesterday after integrating its Claude AI model into its developer tools.

It goes both ways: While even new tie-ups with ShopifySHOP

and EtsyETSY

sparked e-commerce rallies, not every AI-linked stock is cashing in. Recent announcements plunged KlaviyoKVYO

, HubSpotHUBS

, and AtlassianTEAM

over 9%, while travel platforms brace for further disruption. OpenAI CEO Sam Altman calls it “a strange new thing” to watch the weight of his words move markets, but the echoes of dot-com mania are hard for Wall Street to ignore.
