CEX integrating with Polymarket Builder? The Polymarket Builders leaderboard now features Gate Exchange, likely the first mid-to-large CEX to integrate with Polymarket. On its launch day, Gate's prediction market product generated $300,000 in trading volume, ranking 10th on the Polymarket Builders leaderboard. Mechanism-wise, Gate seems to be using a proxy trading logic similar to Alpha, as only 1 trading user was captured via the Polymarket API. It’s likely that more CEXs will follow suit and join the Builders in the future. Keep in mind, Robinhood alone contributed over 50% of Kalshi's trading volume—distribution channels for prediction markets are super important.
