Kalshi. Polymarket. Augur. All names we've heard of. Some of you might even be users. But what's stopping you from placing a trade on something that you can control or influence? It's well known that insider trading is the betting market's biggest fear. They say the system is designed for you to lose as the corporations turn a profit. But how? The truth is, these platforms undertake extensive monitoring, often going to great lengths to ensure that no bet participants are noncompliant with their policies and rules. There's obviously a lot at stake here. Many of these platforms have been found actively analyzing social media, user profiles, and potential connections to prevent fraudulent trades. But out of all of these techniques, the biggest giveaway is easily the win-rate anomalies. If the companies find that one person has an oddly timed trade that's well-placed, who also happens to acquire large sums of money from these trades, it catches their eye. You see, the system is wired for the user to lose. When they see someone turning a profit, it can be quite suspicious.

Across the board, coordinated algorithms scour the web for any sign of linkage between suspected insider traders. They track live Tweets, posts, funding sources, and analogous timing or patterns.
