Prediction Market Activity Expands

Gemini's prediction market is part of the larger adoption of prediction markets. Last week, CFTC Chairman Michael Selig said that the organization won't sit idly as many states have been targeting prediction markets like Polymarket.

However, it has not impacted trading on the platform. Polymarket Builders' weekly trading volume reached $125 million over the past week, marking the third consecutive week above the $100 million threshold,

to an analyst at Dune. Polymarket Builders are third-party teams that create and operate markets on the Polymarket, the largest prediction market. The number of weekly trading addresses exceeded 10,000 for the second straight week.
