Event contract 'combo bets' help drive volume growth on prediction markets

Bundled event contracts, often referred to as combo bets, are playing a growing role in driving trading volume on prediction markets, according to a CNBC report. These combination contracts allow users to bet on multiple linked outcomes within a single transaction.

While combo contracts make up only a small share of total transactions on these platforms, that share has remained consistent even as it contributes to overall volume growth, the report said.

A growing corner of prediction markets

Prediction markets, which let users trade on the outcomes of real-world events, have drawn increasing attention as a growing segment of online trading platforms. The rise of bundled contracts suggests platforms are finding ways to increase engagement by offering more complex betting structures alongside simple single-outcome contracts.

The report did not specify particular platforms, revenue figures, or growth percentages tied to combo contract activity beyond describing their consistent, if modest, share of overall volume.
