Coinbase Stock Falls Amid User Concern Over Internal AI Pivot

Coinbase (COIN) stock fell sharply Tuesday after news emerged that employees without technical expertise are now able to directly release software updates, sparking criticism from customers.

The response brought up painful memories of the company’s data breach in May 2025. Many users said they were considering taking their money elsewhere and criticized CEO Brian Armstrong’s push for faster development.

A Coinbase Trust Wound That Never Fully Closed

For many Coinbase customers, the news arrived with the weight of a story they had heard before.

In May 2025, the company announced a data breach that impacted 69,461 customers, which represented less than 1% of its active users that month.

As an analyst, I’ve uncovered that cybercriminals were able to bribe employees of TaskUs, an outsourcing company, who worked as customer support contractors in other countries. This allowed them to steal data directly from the internal tools used for support operations.

A small number of Coinbase users (less than 1%) had their personal information accessed due to a security incident. Cybercriminals offered bribes to some international support employees who misused their access. Importantly, no passwords, private keys, or funds were compromised, and high-value accounts were not affected. We will provide reimbursement to customers whose information was impacted.

The leaked information contained personal details like names, email addresses, phone numbers, home addresses, dates of birth, partially hidden Social Security numbers, obscured bank account details, images of government-issued IDs, and account balances.

Although passwords and private keys weren’t stolen, the leaked information was used to create phishing emails and trick people into giving up their information.

Adam Cochran, a well-known voice on X (formerly Twitter), criticized Coinbase, stating he wasn’t interested in hearing about fund recovery efforts, but rather what the company was doing to improve its handling of private data. He questioned how a company valued at $60 billion could have such poor data security policies, given its ability to hire skilled professionals.

Coinbase turned down a $20 million ransom request and announced the attempted attack publicly. They also offered a reward of the same amount for information that helps identify and arrest those responsible.

The company eventually predicted cleanup costs might total as much as $400 million, and it also became the target of several class-action lawsuits.

Customers Push Back After Latest Disclosure

Hearing that non-technical employees at Coinbase are now able to deploy live code brought back a lot of familiar concerns right away.

Artificial intelligence is rapidly transforming the workplace. Recently, I’ve seen our engineers accomplish in just days what previously required weeks of effort. Even teams without technical expertise are now creating working code, and many of our regular tasks are being automated, as Armstrong explained in the announcement about recent layoffs.

People with accounts shared numerous complaints on social media, claiming the recent changes were due to ongoing security concerns.

One user expressed concern about non-technical teams deploying code directly to live systems, stating, “It’s pretty unsettling.” They added that they don’t store much cryptocurrency on the platform, as they primarily use it to buy and sell, and this recent situation reinforces their decision to keep limited funds there.

Several other users described how the 2025 incident directly affected them. One person explained that their home address was revealed, leading to ongoing harassment from scammers who try to trick people into giving them information.

We’ve noticed a recurring issue in customer complaints: people are losing trust in our exchange as a safe place to hold their assets. This seems to be because they’re concerned about the skills of some of the people now working on our technical development, assuming they don’t have traditional engineering backgrounds.

It’s a bit scary that teams without a lot of technical expertise are now releasing live code. I’ve already had issues with data leaks in the past, so this is concerning.

Coinbase stock (COIN) dropped nearly 5% when trading began on Tuesday, and was worth $196.21 at the time this was written.

Armstrong Defends the Production Pipeline

Coinbase CEO Brian Armstrong responded to recent criticism on X (formerly Twitter), stating that the company does not release unverified code to its live platform.

All code created by AI undergoes careful review by human experts. We never deploy AI-generated code directly into production without checking it first. This process helps us deliver new features and improvements faster while also maintaining high security standards.

— Brian Armstrong (@brian_armstrong) May 5, 2026

He presented the policy as a way to improve efficiency, not a lowering of standards. It’s unclear if this will calm investors who are still worried about the 2025 security issue, and the stock market seems to be expressing its doubts through declining prices for COIN.

This disagreement highlights a fundamental issue: how much responsibility exchanges should take for protecting users who have already been affected by a previous security breach.
