US stock indexes opened lower Monday as a weekend call by leading AI executives to slow frontier model development hit chip and software shares, while bitcoin rose about 1 percent to near $78,000 and Brent crude held above $107 a barrel two days before a Federal Reserve decision.
Anthropic CEO Dario Amodei said over the weekend that the industry should slow the pace of frontier AI development to let safety measures catch up. OpenAI CEO Sam Altman and Elon Musk, whose xAI builds Grok, voiced agreement, an unusual alignment among rivals that investors read as a signal the current buildout pace carries real risk. Reuters reported Wall Street’s main indexes falling at the open, with Nvidia and other chipmakers taking the heaviest losses.
The damage started in Asia. SoftBank fell as much as 13 percent in Tokyo and SK Hynix dropped more than 5 percent, dragging South Korea’s Kospi down about 3 percent. Memory chips and data center equipment, the physical backbone of the AI trade, led losses across the region. European indexes followed, with the Stoxx 600 down more than 1 percent in early trading.
Crypto decouples, for a day
Cryptocurrencies moved the other way. Bitcoin gained about 1 percent over 24 hours to around $77,800, and ether added roughly 2 percent to near $2,500, according to CoinDesk’s live coverage. The divergence is notable because bitcoin has traded as a high-beta risk asset for most of the year, falling alongside tech stocks in previous selloffs.
Traders offered two explanations. Some argued the AI warning hit equities with concentrated exposure to a handful of data center suppliers, while crypto has no direct earnings exposure to AI capex. Others noted that crypto has its own near-term catalyst this week: a Senate cloture vote on the CLARITY Act Tuesday and the Fed decision Wednesday, both of which have supported positioning. Open interest data from Santiment showed leveraged positions already reduced 13.5 percent in Bitcoin terms last week, suggesting the market de-risked before the events rather than after.
Gold slipped as rate hike expectations firmed, a reminder that the week’s macro calendar cuts across every asset class. The yellow metal had been one of the year’s strongest performers, but hot inflation readings and rising yields pulled money toward cash and short-duration bonds instead.
Oil keeps the pressure on
Brent crude stayed above $107 a barrel with Saudi Arabia’s East-West pipeline still offline and Houthi forces tightening their grip on shipping near Bab el-Mandeb. The pipeline outage removed a major redundancy from global supply, and insurance costs for Gulf shipping routes have climbed for weeks. Energy costs feed directly into the inflation picture the Fed will weigh on Wednesday. Markets put the odds of a 25 basis point hike to a 3.75 to 4 percent target range at roughly 85 to 90 percent, despite public pressure from President Trump to hold or cut.
The meeting is the first under chair Kevin Warsh, and the inflation backdrop is uncomfortable: core consumer and producer price readings came in hot, and the 10-year Treasury yield touched 5 percent in Monday trading. Higher for longer at the short end plus a supply shock at the pump is the combination central banks historically struggle with, and European officials have already warned the Middle East conflict could keep inflation elevated for an extended period. The European Central Bank has revised its own inflation forecast upward and cut growth projections, and traders now expect at least two ECB hikes before year end, a reversal from prewar expectations of none.
The Bank of Japan meets later in the week and is widely expected to raise rates to 1.25 percent, a level last seen in 1995, while the Bank of England decides Thursday. Three major central banks moving in the same week, all in a hawkish direction, is the kind of synchronized tightening that historically compresses valuations for long-duration assets on both sides of the Atlantic.
What to watch Tuesday and Wednesday
Two events inside 48 hours will set the tone. Tuesday at 2:15 p.m. ET, the Senate votes on cloture for the CLARITY Act, which needs 60 votes. Prediction markets put the odds of the bill eventually becoming law this year near 30 percent on Polymarket after President Trump agreed to a stricter ethics provision over the weekend. A failed vote, combined with a Fed hike the next day, is the scenario analysts at Bernstein flagged as a potential drawdown trigger for crypto.
For equities, the question is whether the AI safety chorus was a one-week sentiment event or the start of a repricing. Executives calling for restraint while their companies spend record sums on compute is a contradiction markets have ignored so far. Monday’s session suggests some investors stopped ignoring it, at least for a day. Earnings expectations still look supportive, with S&P 500 companies projected to grow profits about 20 percent across recent quarters, which is the main argument bulls offer against the macro pressure. Volatility gauges jumped too, with the VIX up more than 9 percent in recent sessions, signaling hedging demand is rising ahead of the central bank decisions.
Bitcoin’s ability to hold $77,000 through a stock selloff, an oil spike and a near-certain rate hike will itself be a data point. If the decoupling holds through Wednesday, it would mark the first sustained period in months where crypto traded on its own news rather than the Nasdaq’s. If it fails, Monday will look like a brief exception in a year of correlation.
