Coinbase CEO turns earnings call into unexpected jackpot for prediction market traders

During Coinbase's third-quarter earnings call, CEO Brian Armstrong deliberately mentioned several keywords—Bitcoin, Ethereum, blockchain, staking, and web3—that prediction market traders on platforms like Polymarket and Kalshi had wagered he would say. This spontaneous action, which Armstrong noted he did while tracking the predictions market, resulted in an unexpected win for those bettors. The call also revealed Coinbase's strong Q3 performance, including a 37% surge in transaction revenues to $1 billion, total revenue of $1.9 billion, and a net income of $433 million. Furthermore, Armstrong confirmed Coinbase added over $300 million worth of BTC during the quarter, placing it among the top ten public companies by Bitcoin holdings.
