    Coinbase’s Armstrong Shakes Up Predictions Markets in Q3 Call

    Coinbase boss Brian Armstrong shook up two prediction markets in the final seconds of Thursday’s third-quarter earnings call by dropping a list of crypto buzzwords that Kalshi and Polymarket users bet would be mentioned in the call, resolving all markets to a “yes.” 

    Several Kalshi and Polymarket users were ecstatic that their bets paid off in the final seconds. In contrast, others were understandably rattled to hear that a prediction market could be so easily upended.  

    “I was a little distracted because I was tracking the predictions market about what Coinbase will say in their next earnings call, and I just want to add here, the words Bitcoin, Ethereum, blockchain, staking, and Web3, make sure we get those in before the end of the call,” said Armstrong. 

    The “What will Coinbase say during their next earnings call” markets from Kalshi and Polymarket saw $80,242 and $3,912 worth of bets placed.

    That included 24 punters on Polymarket, where fortunately, no one lost more than $12 on a single bet. 

    Armstrong later on X said it happened “spontaneously when someone on our team dropped a [prediction markets] link in the chat.”

    Armstrong seemed to please more punters than not

    Almost every punter in the comments section was pleased with Armstrong’s last-minute decision to list the crypto buzzwords not mentioned earlier.
