Two threads dominated the hour: a sharp oil retreat on signs of US-Iran diplomacy, and the cost of financing AI. Iranian officials said they could reopen the Strait of Hormuz within two days as part of a deal with the United States ¹, and oil fell 6% as that diplomacy eased supply fears ². Brent slid to $108.41 after Iran's leadership signalled openness to talks ³. Indirect talks continue through intermediaries in Doha, and Trump says no new strikes will come before the Nov. 3 midterms . Washington still needs to address one or two Iranian nuclear sites, however ⁴, and Gulf allies are preparing for a new round of strikes while Iran threatens retaliation ⁵. ADNOC's chief blamed the US-Israeli war on Iran for depleting global oil and gas stockpiles ⁶, and US producers are pocketing $130bn tied to the war while household energy bills climb ⁷. On AI, Oracle began a $20 billion debt and equity raise to fund its infrastructure buildout ^8,9, and its shares fell on the news ¹⁰. Anthropic's amended IPO prospectus lands alongside it, but reports of the figures conflict. One account cites $33 billion in quarterly revenue and a $104 billion loss ¹¹. Another says the loss narrowed to $23 billion ¹². Personnel costs rose to $1.71 billion from $489 million, largely on stock compensation ¹³, and Google received an option to buy up to $10 billion of Anthropic's Class N shares ¹⁴. Marvell agreed to buy Lumentum for $115 billion to expand in AI data centers ¹⁵. All of this follows a rout in which hedge funds erased nearly two years of AI buying in five days ¹⁶. In October the Nasdaq 100 fell 6.66% while the equal-weight S&P 500 rose 5% ¹⁷. Wall Street opened higher Monday in a rebound ¹⁸, and Kevin Hassett dismissed concerns about AI financing ¹⁹. In crypto, Binance reopened withdrawals after hackers the FBI ties to North Korea drained roughly $6.3 billion ²⁰. Separately, Brazil's Mercado Bitcoin froze deposits and withdrawals after more than $40 million in suspicious transfers ²¹. On the eve of the midterms, Trump's economic approval hit a low of 26% ²². He floated pre-emptive pardons for Elon Musk and aides if Democrats take Congress ²³, and a federal judge dismissed a Trump administration suit seeking to block certification of Alaska's Senate results . Also worth noting: a second wave of cyberattacks in a month hit European supermarket fridges ²⁴. Ukraine and Russia both reported fake emergency alerts as the Oleshky truce ended ²⁵; that truce had enabled nearly 800 evacuations . And LXP Industrial Trust's leadership disposed of shares to the issuer at $61.20, including $49.3 million by its CEO ²⁶.
