Coinbase CEO Brian Armstrong surprised listeners during the company’s third-quarter earnings call on Thursday after mentioning nearly every keyword that prediction market traders had wagered he would say.
“I was a little distracted because I was tracking the predictions market about what Coinbase will say in their next earnings call,” said Armstrong as he wrapped up Coinbase’s earnings call, “and I just want to, you know, add here, the words Bitcoin, Ethereum, blockchain, staking, and web3, to make sure we get those in before the end of the call.”
The moment inadvertently handed a win to Kalshi and Polymarket bettors.
