The explosive growth of prediction markets is driven by regulatory arbitrage. They capture immense value from the highly-regulated sports betting industry by operating under different, less restrictive rules for 'prediction markets,' despite significant product overlap.
New platforms frame betting on future events as sophisticated 'trading,' akin to stock markets. This rebranding as 'prediction markets' helps them bypass traditional gambling regulations and attract users who might otherwise shun betting, positioning it as an intellectual or financial activity rather than a game of chance.

Prediction markets are cannibalizing the traditional gaming industry by framing gambling as an intellectual activity. This creates a more compelling 'product' that is already impacting gaming stocks and tourism, while introducing severe societal harms like addiction and new forms of insider trading.
Prediction markets like Polymarket operate in a regulatory gray area where traditional insider trading laws don't apply. This creates a loophole for employees to monetize confidential information (e.g., product release dates) through bets, effectively leaking corporate secrets and creating a new espionage risk for companies.
The true value of prediction markets lies beyond speculation. By requiring "skin in the game," they aggregate the wisdom of crowds into a reliable forecasting tool, creating a source of truth that is more accurate than traditional polling. The trading is the work that produces the information.
Extreme conviction in prediction markets may not be just speculation. It could signal bets being placed by insiders with proprietary knowledge, such as developers working on AI models or administrators of the leaderboards themselves. This makes these markets a potential source of leaked alpha on who is truly ahead.
While praised for aggregating the 'wisdom of crowds,' prediction markets create massive, unregulated opportunities for insider trading. Foreign entities are also using these platforms to place large bets, potentially to manipulate public perception and influence political outcomes.
