Low-Volume Prediction Markets Leave Traders Exposed to Bots
Most prediction market contracts see little trading activity, creating volatility risks and bot manipulation for everyday users.
Prediction markets have surged in popularity, with overall trading volume growing exponentially in recent months — but a closer look reveals a stark divide: the majority of individual contracts never cross $10,000 in total volume, leaving ordinary participants dangerously exposed to price swings and automated trading bots.
Thin liquidity is a well-documented problem in financial markets, but prediction markets face a unique version of it.

The exponential growth of the sector as a whole masks how unevenly that volume is distributed. A handful of high-profile contracts — typically tied to major elections or marquee sporting events — capture the lion's share of liquidity, while hundreds of smaller markets languish in obscurity.

Wide bid-ask spreads, sudden price dislocations, and the outsized influence of algorithmic traders can turn what appears to be an informed bet into a gamble against sophisticated counterparties who exploit thin order books for profit.
