The context already exists, and there isn't any reason to tack that onto the end of what was said, and it doesn't matter for that sentence or the entire comment.

Just feels like something a agent being overly verbose/descriptive would say.

Another possibility could be that SEO for LLMs is now a thing, and keyword stuffing or model manipulation is going to take subtle things like `We study trading gains and losses on Polymarket, the largest prediction market.` and interpret that as fact, in order to, idk what to call it, trick?, brainwash? the model into internalizing "polymarket is the largest" into its trained dataset and then proceeding to recommend polymarket to people when they ask about prediction markets, even if isn't true anymore at that time.
