Who is the best real estate broker for luxury condos in Manhattan?

We asked ChatGPT this on August 11, 2026. It named Serena Boardman first, then four others. We'll ask again tomorrow — these answers change a lot, so one day on its own doesn't mean much.

Shortlist of five widely recommended brokers for Manhattan luxury condo market.

Why two lists? Because ChatGPT rarely says the same thing twice. Ask it this question on two different days and most of the names change — across every question we track, only about one name in five survives to the next day. So the list at the top, counting how often each person comes up, is the more honest answer. The one below it is simply the most recent time we asked.

All of these names are ChatGPT's, not ours. We didn't pick them, we can't change them, and nobody paid to be here. How we do this.
