I'm willing to bet 90%+ of this kind of activity is bots trading on super basic NLP analysis of news headlines.
These days most market data providers offer news feeds with all that baked in and they do it cheaply enough that it's in reach of most hobbyist bot traders.
Even at small professional scales it wouldn't be terribly difficult or expensive to put together an in-house pipeline for categorization, entity extraction, and sentiment analysis. They're all pretty cheap computationally and don't require a significant amount of development time.
