CertiK's "2026 Skynet Prediction Markets Report" shows that prediction markets saw trading volume grow to $63.5 billion in 2025, a fourfold increase, with Kalshi, Polymarket, and Opinion becoming the dominant platforms. However, this growth also brought new risks, including oracle vulnerabilities, abuse of administrator keys, and Web 2.5 architectural issues. The report points out that while prediction markets are legal financial products in the US through a CFTC ruling, they are banned in several EU countries as unauthorized gambling. Furthermore, regulatory differences across US states may further exacerbate compliance complexity. In December 2025, Polymarket's third-party authentication provider experienced a security incident, exposing a centralized failure point in its hybrid Web 2/Web 3 architecture. The study also estimates that during peak airdrop periods, manual trading volume on some platforms reached 60%, severely distorting liquidity metrics. CertiK predicts that 2026 will see enhanced technological privacy and accelerated institutional adoption in prediction markets, but platforms will need to simultaneously address issues such as liquidity maintenance, security infrastructure development, and revenue model sustainability to achieve long-term development.
