• Tech stocks tumble Friday , AI shares lead the way

  U.S. stocks ended Friday broadly lower as a sharp spike in oil prices and a plunge in AI-linked technology shares pressured the market. The S&P 500 fell 84.62 points (1.09%) to 7,659.44, the Dow Jones Industrial Average dropped 175.28 points (0.34%) to 52,002.41, and the Nasdaq Composite lost 572.99 points (2.14%) to 26,140.03. Market participants pointed to rising energy costs as a key driver of the risk-off mood, stoking concerns about inflation and corporate margins. The U.S. dollar weakened against most major currencies, with the yen the main exception, while world equities mostly gained, though Indonesia's IDX Composite plunged 11.57%. Japan's Nikkei 225 rose 1.39% to 65,324.29, Germany's DAX gained 0.95% to 25,622.61, and London's FTSE 100 added 0.38%.

• Cardano holders are being asked to bet $5 million on copper hitting a new record

  Toto Finance is asking Cardano's treasury for 22 million ADA, about $5 million, to buy and tokenize copper, with voting closing Nov. 15. About two-thirds of the budget would buy copper stored in a COMEX-approved warehouse for 18 to 24 months before sale, while the rest covers storage, insurance, audits and Toto's work. If the full budget is spent and ADA's dollar price stays unchanged, copper would need to rise about 49.4% for the treasury to recover its investment, and there is no guarantee the treasury gets its original ADA back. Toto could receive up to 3.36 million ADA, roughly 15% of the request, and would keep its commercial rights to its tokenized-copper business. The proposal would use just over half of Cardano's remaining withdrawal allowance, which would not be replenished under existing rules.

• Bitcoin Core changes security policy as AI makes bugs easier to find

  Bitcoin Core is changing its security disclosure policy because large language models have made some flaws easy to rediscover, so long embargoes offer little protection. Under the new policy, vulnerabilities deemed easily discoverable will be fixed as soon as possible across all maintained major versions, with security advisories published alongside the updates. Other flaws will follow severity-based schedules: low-severity bugs will be disclosed two weeks after the fix is released, while medium and high-severity bugs will be disclosed two weeks after the last affected release reaches End of Life, typically a year after the fix. The change follows a volunteer Bitcoin Red Team report of nearly 5,000 potential issues across 390 projects in August, though only about a fifth had been reproduced at that point.

• Asia FX steadies as oil surge weighs on risk appetite, yen holds gains

  Asian currencies and the U.S. dollar were largely subdued on Friday as investors weighed rising energy costs and geopolitical tensions, while the yen held its gains after a safe-haven rally tied to concerns over global growth and tech valuations. The U.S. Dollar Index was flat at 101.60 by 03:33 GMT, near a three-week low and on track for a second straight weekly loss. USD/JPY edged up 0.1% to 156.90 after a nearly 1% drop in the previous session, as the yen reached its highest level in more than a month. Brent crude near $114 a barrel, after a 4% jump on Thursday following attacks in Saudi Arabia, raises inflation risks for energy importers such as Japan, India and South Korea. The Indian rupee extended its losses, with USD/INR up 0.3% to 95.109, while the yuan hovered near four-year lows; the Fed is expected to hold rates at 3.75%-4.00% on October 28, with ECB and BoJ decisions due on October 29 and 30.

• IonQ vs. Rigetti Computing: Which Quantum Computing Stock Is the Better Buy?

  The article compares quantum computing companies IonQ (ion-based) and Rigetti Computing (superconducting). Rigetti reported Q2 revenue of $5.1 million, up from $1.8 million in 2025, but an operating loss of $28.1 million, and held $541.3 million in cash and investments; it also received a $100 million award from the U.S. Department of Commerce. IonQ posted Q2 revenue of $80.1 million and forecasts 2026 sales of $280–290 million versus $130 million in 2025, though its Q2 operating loss widened to $337.2 million from $160.6 million, and the Elisity deal involves stock valued at up to $1.3 billion. The author judges IonQ the better investment given its consistent revenue growth, says they bought IonQ shares, and notes Rigetti's price-to-sales ratio is more than six times IonQ's.
