Coinbase sent out a notification to users with the result of the Norway vs. Brazil match before it even started. This was reported by a user known as jay_drainjr on X.

for a World Cup game that hasn’t even been played yet and sending factually incorrect notifications to its millions of users as “breaking news”… pic.twitter.com/coD8xY2O0S
The push notification claimed that Norway defeated Brazil 3-2 in a World Cup playoff match, with Erling Haaland scoring two goals. At that time, the game had not yet begun.
“This is what happens when a crypto company uses AI to launch sports prediction markets. [...] It’s dangerous and irresponsible,” commented jay_drainjr.
Coinbase CEO Brian Armstrong responded that he is looking into the situation with his team.
The next day, the head of consumer and business products at Coinbase, Max Branzburg, announced that the platform had corrected the error and updated its systems to prevent similar inaccuracies in the future.
The final score of the match turned out to be different: Norway won 2-1, and Haaland indeed scored twice. Branzburg reacted with a joke:
“Maybe the AI knew something we didn’t.”
The false notification appeared in the “Trends” section, which uses artificial intelligence to generate news summaries based on markets presented on Kalshi. Coinbase integrated data from this platform as part of its Everything Exchange strategy.
In May, the exchange announced a 14% workforce reduction. Armstrong explained that this decision was necessary to optimize costs and more actively implement AI.
In June, the company launched Coinbase for Agents—a service that connects digital assistants to user accounts for trading and other operations. The platform is also involved in Amazon's initiative to launch AI-based payment solutions for agents.
