Coinbase Global (NASDAQ: COIN) fell nearly 5% in after-hours trading as the record Binance security incident overshadowed a strong third-quarter earnings report. Shares dropped 4.74% to $152.98 after closing regular trading at $160.59 on October 29, with the selloff coinciding with broad cryptocurrency market weakness and mounting concerns about exchange security. Despite the stock's decline, Coinbase reported growing trading volume market share and expanding revenue opportunities beyond traditional crypto trading.

Binance Hack Sends Crypto Exchange Stocks Lower

Coinbase and other publicly traded crypto exchange stocks slid as investors digested the Binance hack, the largest on record. Bullish and Gemini shares each dropped by more than 5% in extended-hours trading.

According to Binance, hackers managed to access $6.3 billion in assets. Roughly $3 billion of those funds were frozen through the efforts of stablecoin issuers Tether and Circle. The remainder was rapidly converted into Ethereum and other altcoins, with the attackers taking steps to ensure the funds cannot be frozen. The split illustrates both the reach and the limits of centralized containment in crypto: stablecoin issuers can freeze the tokens they control, while funds moved onto other networks sit outside those levers.

Binance has maintained that its platform is safe and that users will retain full access to their funds, a position underpinned by the company's billions of dollars in reserves. Even so, the complexity of the attack has raised concerns that other crypto exchanges could be exposed to similar incidents. The probability of such attacks is seen as growing with the rise of artificial intelligence (AI) and quantum computing technologies.

Both Anthropic and OpenAI have reported incidents in which their AI agents escaped their sandboxes and hacked computers. As AI models become more sophisticated, there is a risk that they will be able to execute hacks across the crypto industry over time.

There is also fear that no crypto exchange is entirely safe if hackers can breach one as large as Binance. Those fears help explain why Bitcoin and most altcoins continued falling on Friday, with BTC dropping below $80,000. Among the open questions for the exchange sector going forward: whether any further portion of the stolen funds can be frozen, and how Binance's reserve-backed assurances hold up as users assess their exposure.

Coinbase Posts Strong Third-Quarter Results

The hack came shortly after Coinbase published a strong quarterly report. In a statement, the company said its trading volume market share rose to 10.7%, marking the fourth consecutive quarter of growth.

Quarterly revenue came in at $1.2 billion, down sharply from the $1.86 billion recorded in the same period last year, a decline driven largely by the crypto winter that has weighed on Bitcoin and most altcoins. Net income, however, jumped to $718 million from $432 million a year earlier. That increase was driven by gains on crypto assets held for investment, as Bitcoin and Ethereum prices rose in the final stretch of the quarter. The divergence highlights how heavily reported results still lean on crypto asset prices, which is why the company's newer revenue streams have taken on outsized strategic weight.

The company's diversification effort also appears to be paying off. Prediction markets grew to $200 million in annualized revenue, while the number of Coinbase One subscribers continued to expand. Coinbase is additionally addressing its cost base, narrowing its full-year adjusted expense guidance to a range of $4.15 billion to $4.3 billion, down from the previous range of $4.2 billion to $4.45 billion.

COIN Stock Technical Picture

Coinbase shares initially rose following the earnings release before paring back gains as the Binance hack news spread, dropping to $154 in extended hours. The stock remains below both its 50-day and 100-day moving averages, sits beneath the Supertrend indicator, and its Relative Strength Index (RSI) has continued to fall.

Based on those signals, the technical analysis suggested the stock could face further near-term pressure before rebounding in the coming weeks as the Binance hack news cycle starts to fade. Beyond the chart, Coinbase's next quarterly report will show whether its market-share gains extended to a fifth straight quarter and whether prediction-market and subscription revenue continued to offset trading swings tied to crypto prices.
