Trade Desk, UniFirst Soar; Nvidia Falls

Today's biggest winners and losers in the stock market.

On this episode of Stock Movers:

- Trade Desk (TTD) stocks soared Thursday after a report said that OpenAI has held talks with the company about help to sell ads on its flagship ChatGPT platform.

- Nvidia (NVDA) shares fell after US officials have written draft regulations that would restrict AI chip shipments to anywhere in the world without American approval, giving Washington broad control over whether other countries can build facilities for training and running artificial-intelligence models — and under what conditions.

- UniFirst (UNF) stocks rose as much as 17% after Cintas Corp. announced they were in advanced talks to buy UniFirst Corp., according to people familiar with the matter, setting itself up to clinch a years-long pursuit of the rival uniform maker.
