Crypto-related equities tumbled on Friday, October 30, 2026, in the wake of Binance disclosing a record $6.3 billion security breach, according to Decrypt. The breach triggered broad selling pressure across digital asset equities at the market open.[1]

Coinbase and Strategy bore the brunt of the downturn. Decrypt reported that Coinbase fell approximately 12% to trade near $142 early Friday, while Strategy slid about 10% toward $127. Market analysis account unusual_whales noted that Coinbase touched a drop of 12.5% near session lows of $140.50, while Strategy clawed back to a 5% loss after dropping as much as 12% in morning trading.[1][3]

The rout extended widely across mining and trading platforms. According to Coin Bureau, mining companies Hut 8, Riot Platforms, and MARA each dropped 9%, while Robinhood and CleanSpark slipped 8%, and BitMine and IREN fell 7%. Coin Bureau also reported that over $850 billion was wiped out across the broader U.S. stock market at the opening bell, though attached trading charts reflected slightly different midday variations, including a 12.70% decline for Coinbase Global and an 8.46% drop for Robinhood Markets.[2]
