Google Quantum AI reported cutting a critical class of quantum errors roughly 40-fold on its Willow chip, according to a new paper in Science. Instead of building dedicated qubit factories, the technique injects a rough state, runs it through checks and discards the 92% that fail, leaving states with 99.99% fidelity. Breaking RSA-2048 would require error rates around one in 10 billion, and the estimated qubits needed fell from 20 million in 2019 to under one million by 2025. A March 2026 Google whitepaper put Bitcoin's elliptic curve cryptography at under 500,000 physical qubits, while Willow has 105. Justin Drake warns AI-driven mathematics could break elliptic curves first and advises large holders to move funds to fresh addresses that have never signed a transaction, while Coinbase, Sui, Ethereum, Zcash and Near are preparing quantum-resistant measures.

- Bitcoin ETFs just saw their biggest day in a month thanks entirely to BlackRock
U.S. spot bitcoin ETFs took in $526.6 million on Monday, the largest daily net inflow in nearly a month, driven entirely by BlackRock's iShares Bitcoin Trust (IBIT), which pulled in $665.2 million, its biggest daily inflow since Oct. 7 last year, according to SoSoValue data. Fidelity's FBTC lost $83.6 million and Grayscale's GBTC shed $54.9 million, while the remaining funds recorded no net flows. The inflow more than erased last week's $228.5 million of withdrawals, but funds remain about $90.5 million in net outflows for October, according to CoinDesk calculations. Ether funds moved the opposite way, losing $103.3 million in their fourth consecutive session of outflows, with BlackRock's ETHA accounting for $95.4 million of that.
- JPMorgan Bitcoin Forecast Gives BTC a Major Edge Over US Stocks
In its 2027 Long-Term Capital Market Assumptions, released October 19, JPMorgan Asset Management projects a 10% annual compounded return for Bitcoin over 10 to 15 years, its first long-term Bitcoin forecast, above the 7.5% for U.S. large-cap stocks, 8.2% for REITs and 5.5% for gold. Bitwise CIO Matt Hougan highlighted the forecast, though the article notes these are modeled estimates rather than a short-term market call. At the same time, JPMorgan assigns Bitcoin 55% annualized volatility, roughly three times the approximately 18% assumed for U.S. large-cap equities and 17.2% for gold. The bank has not added Bitcoin to its main covariance matrices, citing its volatility and unstable correlations with conventional assets, and instead analyzes it in a separate, smaller matrix. For comparison, JPMorgan projects 7% annually for a portfolio of 60% equities and 40% bonds over the same horizon.
- US Bitcoin ETFs draw $527M in biggest showing since September
US spot Bitcoin ETFs recorded $526.7 million in net inflows on Monday, their largest daily intake in nearly a month and the strongest since Sept. 22, after two weeks of net weekly withdrawals. BlackRock's IBIT led with $665.2 million in inflows, offsetting $83.6 million in withdrawals from Fidelity's FBTC and $54.9 million from Grayscale's GBTC, while other funds recorded no net flows. Despite the rebound, spot Bitcoin ETFs remain about $88 million negative for October. Spot Ether ETFs saw $103.3 million in net outflows on Monday, led by $95.4 million from BlackRock's ETHA, marking their third consecutive week of net withdrawals.
- Iran Delivers Bad News to the World
Iran's crude oil exports have fallen from nearly 1 million barrels per day in July to zero since late August, as the US reimposed a naval blockade from mid-July after a ceasefire deal collapsed. Ship-tracking and satellite data cited by the EU show no crude tankers have berthed at Kharg Island, the country's main export hub, since late August, and Jask port has seen none either. Before the blockade, Iran exported about 1.8 million barrels per day over the 12 months to April, mostly to China, and Chinese refiners are now seeking alternative supplies. Tensions in the Strait of Hormuz have also risen, with 25 vessels targeted in the first two weeks of October, versus 18 in September and 15 in August.
- Bitcoin rally could revive treasury buying, but easy-money days over
Analysts say corporate Bitcoin purchases could accelerate from late 2026 into 2027 if Bitcoin rallies, but investors are likely to be more selective about which treasury companies they fund rather than raising capital indiscriminately as in 2025. Strategy added a net 1,666 BTC in Q3, down from 83,901 BTC in Q2, while other public companies added a net 5,617 BTC versus 45,725 BTC in the previous quarter. Spot Bitcoin ETFs recorded $6.4 billion in net inflows in Q3, though US spot Bitcoin ETFs saw about $229 million in net outflows last week, their second consecutive week of withdrawals. Bitwise noted that a dozen companies that entered during the 2025 treasury boom sold their entire holdings, mostly to repay debt or return cash to shareholders after their stock premiums evaporated.
- US - Iran Peace Deal Hopes Rise as Bitcoin Eyes $90K
A US-Iran peace deal could be announced within days, according to Al-Araby Al-Jadeed, though neither government has officially confirmed a breakthrough. Talks reportedly cover military de-escalation, sanctions relief and Strait of Hormuz restrictions, while Iran's nuclear program remains a major obstacle. Bitcoin traded near $82,500 and would need to rise about 9.1% to reach $90,000, while Brent slipped toward $108 per barrel and WTI hovered near $101. Analysts noted Bitcoin's mixed performance after past US midterm elections, which fall on November 3, and Michael Saylor predicts a recovery above $100,000.

- A Big4 bank cut deposit rates in the morning, then raised them again in the afternoon
VietinBank cut its deposit rates for terms of 6 months and longer on the morning of Oct. 20, then restored them to pre-adjustment levels by the afternoon. Its afternoon rate board showed 3.5% per year for 6 to under 12 months, 5.9% for 12 to under 24 months and 6% for 24 months and longer, versus 3%, 5.4% and 5.5% in the morning. Rates for terms under 6 months stayed unchanged, including 2.1% for 1 to under 3 months and 2.4% for 3 to under 6 months. The move came as banks followed the State Bank of Vietnam's guidance to cut deposit rates by at least 0.5 percentage points for terms of 6 months and longer, and Vietcombank and Agribank were among those reducing rates.
- IVV vs. SPY: Which S&P 500 ETF Is the Better Buy for Long-Term Investors?
The article compares two ETFs that track the S&P 500, iShares Core S&P 500 ETF (IVV) and State Street SPDR S&P 500 ETF (SPY), which have nearly identical holdings. The main difference is the expense ratio: IVV charges 0.03% a year, one-third of SPY's 0.09%, and its distribution yield is about 1.1% versus 1% for SPY. SPY's high liquidity remains valuable for active traders. The article concludes that IVV is the better choice for long-term investors, since lower costs can compound over time.
- Warren Buffett Is Issuing a Stark Warning About the Stock Market. Here's What History Says Comes Next.
Warren Buffett has warned that investors are taking on too much risk, likening the market to 'a church with a casino attached' and saying people have never been in a more gambling mood. The article points to the S&P 500 Shiller CAPE Ratio, which has stayed above 40 since May of this year; historically, the only other time it held above that level for months was during the dot-com bubble, when it peaked around 44 before the bear market began in March 2000. The article notes that 40 is not an automatic trigger for a downturn, and no metric can predict timing. It suggests investors focus on quality stocks with solid fundamentals and be ready to hold them for at least a few years.
- Early Uber Investor Jason Calacanis Predicts Waymo Could Buy Lucid Or Rivian — Calls Its Chinese-Car Optics ‘Really Bad’
Early Uber investor Jason Calacanis predicts Waymo will buy Lucid Group (LCID) or Rivian Automotive (RIVN), arguing that its reliance on Chinese-made Zeekr vehicles creates cost and reputational problems. He says the arrangement is technically not illegal today, but Waymo would need to pay a tariff of over 100%, and it has drawn national-security concerns on Capitol Hill. According to Semafor, Waymo aims to grow its fleet from about 4,000 vehicles to 8,000 by the end of 2026 and 20,000 by the end of 2027, after closing a $5 billion term loan and a $16 billion equity raise this year. Uber has committed to buying at least 35,000 Lucid vehicles, while its Rivian deal starts with 10,000 autonomous R2 SUVs, with rides expected to begin in 2028. Calacanis, who recently bought small stakes in Lucid, Rivian, WeRide (WRD) and Pony.ai (PONY), expects consolidation in the autonomous-driving sector within 24 months.
- Prediction: Oct. 21 Will Be a Huge Day for the Stock Market
The article predicts October 21 could be a pivotal day for the stock market, as Meta Platforms (META) becomes the first of the "Magnificent Seven" tech giants to report third-quarter earnings after the close. In its latest quarter, Meta's total revenue rose 28% to $60 billion, with ad revenue at $59 billion. Investors will be watching whether its capital spending, now about 35% of revenue, is translating into growth. Meta's report could hint at the earnings outlook for other tech giants and set the direction for the S&P 500 in the coming days, with the first trading session after the report on Thursday.
- BlackRock files for third Bitcoin ETF, still no Solana or XRP
BlackRock has filed a preliminary prospectus with the SEC for the iShares Bitcoin Managed Protection ETF (PBIT), which would mark its third Bitcoin ETF filing. Instead of holding Bitcoin directly, the fund would use options linked to IBIT across three overlapping sets, aiming for limited downside protection in exchange for capped gains. Each options tranche initially targets a maximum loss exposure of about 10%, before fees and expenses. BlackRock warned the fund offers no fixed protection start value, floor or cap, so investors could face bigger losses. IBIT, the largest spot Bitcoin ETF with $65.7 billion in net assets, and ETHA, with $8 billion, are already in BlackRock's lineup, while it has no US spot ETFs for Solana or XRP yet.
