Events in this era

Trump Tariff Pause

At 1:18 pm Eastern on April 9, 2025, President Trump posted on Truth Social that he was pausing most reciprocal tariffs for 90 days. AI trading systems reading Truth Social detected and executed on the post within milliseconds. By the time the news wire services ran the headline, the S&P 500 had already moved up roughly 4 percent. It closed up 9.5 percent, the largest single-day gain since the 2008 crisis.

Pentagon Fake Image

An AI-generated image showing an explosion near the Pentagon spread across Twitter from several verified-but-impersonating accounts. Algorithmic trading systems scanning social media for news signals detected the image and began selling equities within seconds. The S&P 500 briefly dipped about 0.3 percent before the image was debunked and markets recovered. A small event, but the first clear case of generative AI directly moving US stock prices.
