Tech & Finance Daily Briefing — September 15, 2026
10 evidence-backed technology and finance stories shaping the day.
Markets price 92.4% probability of Fed rate hike at September meeting
What happened
CME FedWatch now puts the probability of a Federal Reserve rate hike this week at 92.4%, up from prior levels, with only a 7.6% chance of rates staying unchanged. A Reuters survey separately found 86 of 101 economists expect a 25-basis-point increase at the September meeting, and 37 of 70 expect at least two hikes by end-March 2027.
Why it matters
The shift above 90% in market pricing and the Reuters consensus mark a decisive break from the earlier fragile expectation that rates would stay on hold. Economists now see the September move as the first hike since July 2023 and no longer expect cuts in 2027, with Bank of America's Stephen Juneau saying only very weak data would cause the Fed to skip.
Trump rejects AI safety warnings, prioritizes U.S. lead over China in development race
What happened
President Trump publicly rejected calls for AI guardrails, calling fears of AI taking over the world a "hoax" and attacking critics, including Anthropic CEO Dario Amodei, as a "sick conspiracy" aimed at slowing America's lead over China. He argued the only guardrail needed is a "high IQ president" and said slowing down would only work in China's favor.
Why it matters
The president's dismissal of AI risk warnings signals the White House will not pursue tighter federal regulation despite urgent calls from industry leaders, including Anthropic's CEO. Trump framed the debate as a competition with China, arguing that any slowdown would cede advantage, which sets the administration's policy direction against the growing push for guardrails.
OpenAI launches GPT-Live-1 API with full-duplex voice and interruption handling
What happened
OpenAI launched GPT-Live-1 in its API, a native full-duplex voice model that can listen and speak simultaneously and handle interruptions smoothly.
Why it matters
The launch moves voice AI from turn-based interaction to continuous, interruptible conversation, a capability that could make API-based voice agents feel more natural and responsive in real-time applications.
Apple launches Siri AI beta in English, excludes EU initially
What happened
Apple officially launched Siri AI, powered by a new generation of Apple Intelligence, and began rolling out related feature updates in iOS 27. The assistant is initially available in a test version to English-language users, with expansion to French, Japanese, Korean, Portuguese and Spanish planned for next month, while the initial release excludes the EU on iOS, iPadOS and watchOS.
Why it matters
The launch marks Apple's move to position Siri as a more capable, personalized assistant with personal context understanding, broad knowledge, screen awareness and expanded system-level app operation. The staged rollout and EU exclusion indicate a controlled deployment strategy for a major AI feature across Apple's platforms.
AI CEOs call for development slowdown, sending tech stocks and markets lower
What happened
US stock indexes fell on Sept. 14, 2026, with the Nasdaq leading declines as chip stocks dropped after AI company executives called for a slowdown in AI development. The S&P 500 also fell amid rising oil prices.
Why it matters
The declines show that investor sentiment toward AI-linked technology stocks has shifted in response to calls from within the industry for slower AI development, while higher oil prices added separate pressure on the broader market.
Apollo Global in talks to acquire Johnson & Johnson’s DePuy Synthes unit for $20 billion
What happened
Johnson & Johnson is reported to be in talks to sell its DePuy Synthes orthopaedics business to Apollo for about $20 billion.
Why it matters
A deal of this size would mark a significant divestiture by J&J and a major private-equity move into the orthopaedics market, with the two reports indicating the talks have advanced from rumour to reported negotiations.
Bank of America raises S&P 500 year-end target to 7,400, warns of overdue correction
What happened
美国银行将标普500指数2026年底目标位从7100点上调至7400点，并将未来12个月目标位设为7800点。该行美国股票及量化策略主管Savita Subramanian表示，长期看涨逻辑依然成立，但同时警告市场正进入季节性疲软期，并认为回调已经推迟太久。
Why it matters
即便上调目标位，新的7400点年底预测仍较标普500指数上周五收盘点位低3.4%，在20多位策略师中仍属最悲观观点之一。Subramanian同时警告通胀风险和美联储加息可能性，称任何推高融资成本的催化因素都可能加速市场回调，显示其上调目标并非转向乐观，而是在维持谨慎立场下对长期看涨逻辑的有限修正。
OpenAI CEO Sam Altman rules out 2026 IPO, citing AI safety concerns as ‘ill-advised’
What happened
OpenAI CEO Sam Altman said the company will not hold an IPO in 2026, citing AI safety concerns and calling even a 10% chance of AI-driven human extinction by the end of the decade "unacceptable."
Why it matters
The statement removes near-term IPO expectations for OpenAI and frames safety governance as a direct constraint on its corporate strategy, with Altman arguing that profit incentives must not override risk management.
Automattic board resigns after placing CEO Matt Mullenweg on leave, then reinstates him
What happened
Automattic's board has been removed, according to sources, days after board members voted to place chief executive Matt Mullenweg on leave.
Why it matters
The reported removal of the board escalates the leadership crisis at Automattic, indicating that the dispute over Mullenweg's status has moved beyond a temporary leave into a broader restructuring of the company's governance.
Markets fully price in five Bank of England rate hikes by end of 2027
What happened
Market pricing now fully reflects five 25-basis-point rate increases by the Bank of England through the end of 2027, while Citi revised its forecast to expect hikes in Q4 2026 and Q1 2027 after previously projecting rates on hold until Q2 2027.
Why it matters
The shift signals a materially more hawkish outlook for UK monetary policy, with traders and a major bank moving in the same direction on the same day. Citi's change is especially notable because it abandons a previously expected hold through Q2 2027 in favor of near-term tightening.
