Armstrong said this in a reply to a post in which a Coinbase customer complained about receiving three notifications about college basketball within an hour. The customer also said that the crypto exchange was “trying to get their customer base hooked on sports gambling, so that they can extract even more exorbitant fees.”
In his reply, Armstrong said: “Looks like there was a bug on targeting for these push notifications — getting fixed now. Apologies for the trouble, and thank you for raising it.”
Addressing the issue of prediction markets themselves, Armstrong said Coinbase aims to be an “everything exchange” that enables people to trade anything that’s legal. He added that the company doesn’t want to push anything on anyone, and that in this case, with the notifications, the company made an error that it has now fixed.
Coinbase announced in December 2025 that it was entering the prediction markets game by allowing access to prediction markets in the U.S., initially via market flow from Kalshi and later supporting contracts from other prediction market platforms as well.
The company said at the time that this offering would allow users of its exchange to manage their prediction market positions alongside existing crypto, equities and cash balances.
Within days of this announcement, Coinbase expanded its new prediction markets business by acquiring prediction markets startup The Clearing Company.
In February, during Coinbase’s fourth quarter earnings call, company executives highlighted the crypto exchange’s diversification plays and stressed that the digital asset industry’s next phase will be tied to payments, financing and programmable financial services.
“The Everything Exchange is working,” Armstrong said during the call. “In 2025, we drove all-time highs across our products: Coinbase One subscriptions reached 1 million, trading volume and market share doubled, and USDC held on platform reached an all-time high.”
Coinbase’s Everything Exchange concept, which is central to the company’s current narrative, encompasses three layers of activity: trading, financial services and applications.
