Mercado Bitcoin, Brazil's largest crypto exchange, said a security incident on November 2 led it to suspend deposits and withdrawals, and that no customer lost money or had data leaked. The exchange says it will cover the losses itself, though it has not said how attackers got in. Loss estimates vary: the exchange cites about $38 million, Hypernative more than $40 million, Arkham at least $46 million and Chainalysis about $49 million. The exchange says it has blocked $11 million with partners including Tether and Circle, while Tether froze more than $4.5 million in USDT tied to the incident. Services remain suspended with no restart date, days after a $6 billion theft at Binance that the FBI blamed on North Korea's TraderTraitor group; Mercado Bitcoin has not linked the two.

- The Biggest Crypto Hack in History Just Happened. Here's What the $6.3 Billion Breach Means for the Crypto Market.
Binance said on Oct. 29 that hackers had stolen about $6.3 billion, which the article describes as the biggest crypto hack in history. After the announcement, Bitcoin fell 5.6% within 24 hours and BNB dropped 6.2%. Binance had a rainy-day fund worth around $1 billion and has set aside more than $6.3 billion of its own capital to restore affected customer balances, so direct losses appear covered. Tether froze more than $1.5 billion of USDT and Circle froze $800 million of USDC tied to the theft, and the article says the major blockchains themselves were not breached. More than $3.3 billion was lost to hacks and scams in 2025, and more than $8.7 billion has been lost in 2026 so far.
- Weekly Wrap: Crypto Plunges After Binance Hack
Bitcoin fell 5% to $77,000 and Ethereum fell 4% to $2,240 on the afternoon of Oct. 30, after reports of a $6.3 billion theft at Binance, described as the worst cryptocurrency attack ever. Binance temporarily suspended withdrawals, expects to resume them within 48 hours, and pledged to cover all losses, but reports say institutions are pulling assets from other exchanges. Elsewhere, Ripple secured a U.S. national trust bank license, while Datavault AI said it cannot access a large part of its Bitcoin and will restate its results, reducing reported assets by $92.2 million. Visa said its annualized stablecoin settlement volume surpassed $25 billion, a tenfold increase from a year earlier. Strategy's CFO Andrew Kang will step down on Nov. 5.
- Worried About Crypto Hacks? Buy Bitcoin Proxies in Stock Market Instead, Say Wall Street Firms
Analysts at Cantor Fitzgerald, TD Cowen and Compass Point say the roughly $6.3 billion Binance hack, the largest crypto theft ever, is unlikely to derail the broader market's recovery. Cantor's Ramsey El-Assal noted stablecoin issuers froze about $3 billion of the stolen funds, including over $1.5 billion by Tether, and said he would buy on weakness, expecting Coinbase, Robinhood and Strategy shares to recover. TD Cowen views the breach as a Binance security problem rather than a Bitcoin one, while Compass Point says Binance has more than enough liquidity to cover the shortfall, though reimbursements could strain stablecoin supply. Moody's Ratings is more cautious, citing hot-wallet cybersecurity risks and concentration risk at centralized intermediaries, with broader impact depending on final losses and confidence. Binance has set aside $6.34 billion to cover losses, the Secret Service and FBI have opened a probe, and TRM and Chainalysis link the hack to North Korea's TraderTraitor group.
- Morning Minute: Binance’s $6.4B Hack Overshadows Hyperliquid’s Biggest Day
An attacker stole about $6.4 billion from Binance, by a wide margin the largest crypto theft on record and roughly four times the $1.5 billion taken from Bybit in February 2025. The funds moved across three blockchains: about $3.5 billion in ETH, $1.4 billion in BTC and $630 million on Tron, with final accounting still underway. Tether and Circle froze about $2.39 billion of the stolen tokens (43% of the haul), while Aave froze its V3 and V4 markets on Ethereum to guard against bad debt. Binance said it has reserved over $6.34 billion in company funds to cover losses, and ZachXBT said the funds were commingled with the $388 million Bitget exploit and believes the same North Korean hacker group was behind both. Markets fell on the day, with over $1.33 billion in positions liquidated, after HYPE had surged on news that Intercontinental Exchange is investing in trade.xyz.
- Binance's $6.3 billion hack: What we know and what comes next
Binance suffered a hack with an estimated impact of $6.3 billion, with about $3 billion in assets frozen so far and the exchange pledging to cover all losses. TRM Labs attributed the attack with high confidence to TraderTraitor, a North Korean state-sponsored hacking unit, and Chainalysis also linked it to the same group. TRM Labs estimated about $6.36 billion was moved from Binance wallets across 10 blockchains, mostly within about 20 minutes, after preparations began at least 36 hours earlier. Stablecoins such as USDT and USDC are easier to recover because their issuers can freeze and reissue them, while bitcoin and ether are harder to recover. Fundstrat's Sean Farrell said the attack does not currently appear to pose meaningful solvency risk, given that roughly $3.3 billion remains unfrozen and the roughly $1.2 billion SAFU fund could cover part of the losses.
- 'Whale' Investors Rush to Pull Crypto Off Exchanges After Binance Hack
Institutional investors are rapidly withdrawing assets from centralized exchanges after the Binance hack to reduce security risks, according to CoinDesk, though the size of these outflows and their destinations have not been determined. Binance estimates total stolen assets at about 6.3 billion USD, of which around 3 billion USD has been frozen, including 2.3 billion USD in the stablecoins USDT and USDC. The main cause may involve a compromised laptop belonging to an engineer; Binance has temporarily suspended withdrawals, and co-CEO Yi He said the platform will cover all losses from the attack. Bitcoin dipped to a low of about 76,460 USD, and total liquidations reached 1.53 billion USD over 24 hours, nearly 84% of them long positions.

- What Cirrus Logic (CRUS) Said on Its Q2 Earnings Call
Cirrus Logic reported fiscal second-quarter revenue of $559.5 million, up 22% from the prior quarter, as higher smartphone volumes and more content per device offset weaker PC and general-market sales. It forecasts December-quarter revenue of $510 million to $570 million, partly because some sales shifted into September, and expects gross margin of 51%–53% for the foreseeable future after calling September its high point. The company plans targeted price increases and expects fiscal 2027 operating expenses to rise as it invests in R&D. PC demand is weighed by memory and component shortages and delayed launches, though existing design wins remain in place. Cirrus also completed its INVENTVM acquisition and authorized up to $500 million in additional share repurchases.
- The Deal With Meta & OpenAI Just Cost AMD $1.1 Billion
AMD booked a $1.1 billion noncash charge in the third quarter tied to its chip deals with OpenAI and Meta, the first time these agreements hit its reported earnings. The charge equals 66 cents per diluted share and mainly reflects a higher share price and revised estimates of whether customers will meet milestones, as AMD began shipping Instinct MI450 accelerators. Each customer holds a warrant to buy up to 160 million shares at 1 cent apiece, which would give them about 16% of AMD's enlarged share count if fully exercised. Revenue reached $13.4 billion, and the data center segment hit a record $8.5 billion, up 97% from a year earlier. Free cash flow fell to $554 million from $1.56 billion as inventory rose about $3 billion to roughly $11.5 billion.
- Why Alphabet Stock Popped on Wednesday
Alphabet shares rose as much as 5.9% on Wednesday and closed up 3.2% after Democrats took control of both the House and the Senate in the U.S. midterm elections. A prominent voter issue was stricter oversight of data centers, with an estimated 50 ballot measures nationwide, many seeking moratoriums. Texas accounts for 41% of data center capacity scheduled to come online in 2028, and governor-elect Gina Hinojosa promised a moratorium until the legislature studies the facilities' effects. The article argues a moratorium would likely hurt competition and benefit hyperscalers like Google, even though the stock fell 13% in one day after its Q3 report, its largest single-day drop, on negative free cash flow of $9 billion and roughly $200 billion in planned 2026 capex, while Google Cloud revenue rose 103% to $30.7 billion.
- Steve Weiss Says the Midterms Just Put a Lid on AI Spending. Here's Who Could Get Hurt
After Democrats took control of Congress and newly elected governors pledged to limit data center development, AI infrastructure stocks fell sharply while chipmakers barely moved. Steve Weiss told CNBC the market sees the Democratic win as a forced restraint on capex, since companies could not spend what they committed under a moratorium on new data centers, especially in Texas, where 30% of projects are located. Vistra and Vertiv fell by double digits, while NVIDIA and Broadcom slipped far less, because chips can be sold to projects in other states or countries. Morgan Stanley's Ariana Salvatore argued that a Republican-controlled Texas legislature would limit sweeping changes, while GLJ Research's Gordon Johnson said the Texas result could delay 13 gigawatts of planned data center power.
- Trump committee hearing on Fed Governor Lisa Cook rescheduled to Dec. 14
A special committee appointed by President Donald Trump has rescheduled the hearing for Federal Reserve Governor Lisa Cook to Dec. 14, a White House official said Wednesday. Trump set up the “committee of inquiry” in early October to investigate allegations that Cook made false statements related to “one or more mortgage instruments.” The New York Times first reported the rescheduling.
