Bitcoin's seven-day average hashrate has recovered above 1 ZH/s (equal to 1,000 EH/s), its highest level since March 3, according to BlocksBridge. Mining difficulty rose 5.92% on Oct. 16, with another 5.16% increase projected at the next adjustment, roughly 11.4% across two consecutive adjustments. Although publicly traded miners' realized hashrate fell 23% as they shifted capacity to AI, smaller and mid-sized miners may be buying used equipment such as Sazmining's Antminer S21 XP units hosted in Paraguay and Texas. It remains unclear how much of the resold hardware came from public miners or has returned to the network. Some observers see rising hashrate as an indirect bullish signal, a view CryptoQuant founder Ki Young Ju expressed on X.

- Bitcoin miners plunge up to 13% in Wall Street's worst selloff since July
US stocks suffered their sharpest selloff since July on Wednesday after hotter-than-expected inflation data hit technology and AI infrastructure companies. The S&P 500 fell 1.1% and the Nasdaq Composite dropped 1.9%, while the Dow ended down 0.1%. Bitcoin miners that have expanded into AI infrastructure were hit hard, with TeraWulf falling 12.64% and Core Scientific, Cipher Mining and IREN each losing more than 12%. US consumer prices rose 3.7% in September from a year earlier, above the 3.6% forecast, mainly due to higher gasoline prices from the Middle East war, which nudged up expectations of an October Fed rate hike. However, San Francisco Fed President Mary Daly said there was no urgency to act this month.
- Global AI Rebound Lifts Crypto Market Sentiment
Renewed optimism around the global AI trade, driven by strong earnings outlooks and robust AI demand signals from SpaceX and Super Micro Computers, lifted tech stocks and crypto markets alike. Total crypto market capitalization rose 2.5% to $2.79 trillion, and Bitcoin hit a 24-hour high of $83,593. About $283 million in positions were liquidated, with $208 million from short positions, indicating a mild short squeeze. Spot Bitcoin ETF net inflows fell to $23 million from $527 million on Monday, while Ethereum rose 3.2% to $2,454.87. Zcash gained more than 12% after its NU7 network upgrade schedule was confirmed.

- ‘Wow, it’s a real discovery’: Claude cracks a 25-year NSA number mystery
An Anthropic AI model traced five seeds for NIST elliptic curves, supplied by the NSA in the late 1990s, to an ordinary random-number generator fed with 1997 and 1998 timestamps, in under 30 minutes. The finding makes a hidden NSA backdoor less likely and requires no action from NIST curve users, though questions remain about how some elements were chosen. Bitcoin was not affected because it uses secp256k1, a simpler curve with little room to hide a weakness, though sufficiently powerful quantum computers could eventually pose a separate threat. The 25-year puzzle had a bounty that started at $12,288 and could rise past $36,000 if donated to charity.
- Bitcoin, ether slip and rebound as South Korean stocks slide on AI-related concerns
Bitcoin dipped below $81,000 before recovering above $83,000, while ether fell as low as $2,400. South Korea's equity benchmark plunged 5.5% on Tuesday, led by Samsung Electronics and SK Hynix, which fell 7% and 10%, on concerns over AI investment and advances in memory chips at China's CXMT; the index is roughly 38% below its June all-time high. In derivatives, 24-hour futures volume rose 66% to $212 billion, while open interest fell 1.58% to $143.4 billion and liquidations rose 284% to $813 million, indicating leverage is being unwound rather than added. Investors are positioning ahead of the U.S. CPI report, forecast at 3.6% year over year, and earnings from JPMorgan Chase, Goldman Sachs and Citigroup.
- TeraWulf Jumps 8% as CEO Says Power Demand Remains ‘Extremely Strong’; Applied Digital Surges 9%, IREN Climbs 6%
TeraWulf shares rose 8% to $12.95 in afternoon trading after CEO Paul B. Prager wrote on X that demand for power “remains extremely strong,” that the company’s site is “energized” to meet it, and that shareholders would not be diluted. He said customers would likely need outside funding but TeraWulf would not take on that financial risk, and that the next data center building at Lake Mariner, leased to Fluidstack, is on track for delivery this quarter. Applied Digital rose 9% to $21.17 and IREN climbed 6% to $28.11, while the CoinShares Bitcoin Mining and Digital Power ETF gained 3% to $32.43 against a 0.6% rise in the SPDR S&P 500 ETF Trust. The article links the rally to power scarcity, including Elon Musk’s comment on the earnings call that the infrastructure to supply and cool electrical equipment is “somewhat of a limiting factor” for superintelligence. The next test for TeraWulf is whether the Lake Mariner building is delivered on schedule this quarter.

- Musk's wants to merge SpaceX and Tesla: Here's what to know
Musk said SpaceX and Tesla have formed special committees to study a merger, which would be worth about $3.5 trillion combined and would be the largest corporate deal in history. SpaceX, valued at about $2 trillion after a record listing this year, absorbed Musk's AI startup xAI in February, while Tesla is valued at about $1.5 trillion. Musk holds about 82 percent of SpaceX's voting power but only about 20 percent at Tesla. Dan Ives puts the odds of a deal at 90 percent by early 2027, though Musk called the requirement of a majority of all Tesla shares 'quite a high hurdle'. Loyal retail investors hold an estimated 25 to 27 percent of Tesla shares, and legal obstacles appear slight because both companies moved their incorporation to Texas from Delaware.
- CoreWeave and Nebius Stocks Are Crashing. Time to Buy the Dip?
Shares of Nebius and CoreWeave each fell 25% in the week of October 12 to 16. The sell-off stems from the yield on CoreWeave's debt in the secondary market surging to 15%, versus roughly 5% on Treasuries, which pushes the debt into 'distressed' territory and signals doubts about its ability to meet obligations. Nebius sold off in sympathy as a fellow neocloud company. The bigger concern is that both companies must keep issuing debt to fund data centers, and if yields are high at issuance, the assumption of nearly unlimited cheap capital could be challenged. The author says it is unclear whether now is the time to buy.
- Disney’s multiplatform Super Bowl plan frustrates ABC affiliates
ABC station owners are irritated that Disney is airing the Super Bowl across several platforms, including Disney+, ESPN2, NFL Network and ESPNU, even though the game is already on ABC and ESPN. A station group CEO estimates that the combined platforms could cut broadcast ad revenue by up to 35% compared with last year. Local affiliates typically earn about 3% of annual ad revenue from the Super Bowl and pay network owners reverse retransmission fees, but Disney+ lacks geofenced ad insertion, so affiliates cannot sell ads to streaming viewers. Disney says national commercials will be identical on all platforms and that streaming major live events is standard industry practice. Super Bowl LX drew 125.6 million viewers in February.
- Meta’s deal to keep Zuckerberg in California adds fuel to wealth tax debate ahead of election
Meta says Mark Zuckerberg will remain in California for eight years and has created a new stock plan that could help cover his taxes if Proposition 40, a 5% tax on Californians worth over $1 billion, passes on Election Day on Nov. 3. According to a filing released with its third-quarter earnings, Meta will issue non-voting Class C shares starting in January, and Zuckerberg can sell or transfer up to 20% of the shares granted to him without affecting his majority voting control. The filing says Zuckerberg’s leadership is crucial to the company’s growth and its AI ambitions, including Meta Superintelligence Labs. Most of the tech industry opposes the measure, while a recent Citrin-Politico poll found 46% in favor and 43% against, suggesting it may fall short of the majority support it needs.
- Nasdaq sell-off: A momentum unwind 'for the record books'
Matt Stucky, chief portfolio manager for equities at Northwestern Mutual Wealth Management, calls Thursday’s sell-off in the Nasdaq Composite (^IXIC) a momentum unwind “for the record books.” He says the market spent the first half of 2026 driven by a beta and momentum trade led by semiconductors, but in the third quarter, as rates rose, money shifted into quality stocks. He does not think the sell-off is justified by fundamentals, arguing that institutional portfolio managers swapping out of factor positions can drag down whole baskets of stocks. In semiconductors, spot rental rates for Nvidia Blackwell chips are higher than a month ago, showing tightening compute supply, even as financing costs rise and investors worry about neocloud business models and the rising cost of insuring their bonds.
- Dune launches real-time data feeds covering 200 onchain trading venues
Blockchain analytics platform Dune has launched real-time market data feeds covering more than 200 onchain trading venues, aiming to bring this data into the systems of traditional financial institutions. The feeds draw trade data from 12 blockchains, including Ethereum, Solana and Base, about one second after execution, covering both spot trading on decentralized exchanges and perpetual futures on Hyperliquid and Lighter. Early clients include quant funds, market makers, asset managers and bank trading desks, which use the data to assess liquidity and compare prices, though Dune did not name them. Meanwhile, the tokenized stock market has grown sharply, with distributed value reaching $3.58 billion, but 16 companies, including Microsoft, Alphabet and Goldman Sachs, have objected to their shares being traded on OKXICE’s proposed platform, and liquidity remains fragmented.
