From fear to greed and back again: AI is taking Wall Street to extremes

Curated by Shubham · TechCapsules · Sep 29, 2026

AI-summarised brief · reviewed before publication

Over the past two weeks Wall Street has swung dramatically on artificial‑intelligence stocks, first shedding and then regaining hundreds of billions of dollars in market value. The volatility began on September 12 when Anthropic CEO Dario Amodei urged a slowdown in cutting‑edge AI development, a stance quickly endorsed by OpenAI’s Sam Altman and SpaceX founder Elon Musk. Investors interpreted the call as confirmation of industry warnings about existential AI risks, prompting a sharp sell‑off; the Nasdaq 100 fell 1.5 percent between September 14‑15, erasing roughly $600 billion in equity. The panic receded when Meta’s new Muse assistant generated enthusiasm, lifting Meta shares 11 percent and spurring a rally in AI‑linked hardware firms such as Intel and AMD, which each rose over 9 percent, helping the Nasdaq 100 post its first record since early June.

Bank of America says Meta’s Muse highlights a new risk for Apple’s…

Bank of America analyst Wamsi Mohan warned that Meta’s Muse AI agent could erode Apple’s services revenue by capturing discovery, referral, and transaction flows that currently go through Apple’s ecosystem. Muse, now the top free app on the U.S. App Store with over 3.4 million downloads, can browse the web, book trips, and process payments via Shopify, Expedia, and PayPal. Apple’s shares fell 2.5 % after the note, yet Mohan maintained a “Buy” rating and $370 target, citing Apple’s privacy and installed base as strengths.

💡 The rise of autonomous AI agents threatens to shift control of user intent from platform owners to third‑party services, potentially reshaping the economics of app ecosystems. Apple’s response will determine whether it can retain its dominant role in guiding consumer transactions.

America.gov gets really weird when you ask it about Minecraft, but it’s…

The U.S. government unveiled its first public‑facing AI chatbot, America.gov, developed with Google and SpaceXAI. Designed to withstand red‑team testing, the bot has not been easily jailbreaked. When queried about Minecraft, it produced an 1,800‑word monologue that mirrors the game’s “End Poem,” sparking speculation about embedded Easter eggs. The chatbot also confirms Joe Biden’s 2020 election victory, a fact still contested by former President Trump. The incident highlights the bot’s unexpected creative output and the challenges of deploying AI in a public‑facing role.

💡 The unexpected Minecraft reference shows how even tightly controlled government AI can surface unanticipated cultural content, raising questions about oversight and content filtering in public tools.

The CEO must become the Chief AI Officer

Corporate planning in the Philippines is shifting focus as executives prepare 2027 budgets amid inflation, interest rates, geopolitical tensions, and shifting consumer demand. A new priority has emerged: the strategic impact of artificial intelligence. The author argues AI is not merely another tech upgrade but a systemic rupture that reshapes knowledge work across research, coding, marketing, finance, and HR. AI can accelerate, augment, or eliminate tasks, demanding CEOs embed AI considerations into core strategic planning rather than treating it as an operational add‑on.

💡 AI’s transformative reach forces companies to rethink their business models, workforce design, and competitive positioning, making it a decisive factor in long‑term viability.

Muse Got Here First But This Agentic AI Will Supercede It Soon

Meta launched its agentic AI model, Muse Spark 1.1, across WhatsApp, AI glasses and business agents, claiming early consumer reach. Google countered with Gemini, now deployed at scale in its cloud and integrated into Android, Maps, Gmail and Google Pay, giving it an OS‑level advantage. In Q2, Google’s revenue rose 24.2% to $119.8 billion, with Cloud up 82% and nearly 90% of Fortune 100 firms using Gemini Enterprise. Meta’s revenue grew 28% to $117 billion, but earnings per share missed estimates and legal and severance charges cut operating margin to 31%. Both firms reported similar forward price‑to‑earnings multiples, yet Google’s infrastructure spending and debt capacity dwarf Meta’s, while Meta’s cash flow remains negative. The structural edge of an on‑device agent could erode Meta’s head start despite its larger user base.

💡 An OS‑embedded AI agent reduces friction for enterprise workflows, positioning Google to capture high‑value corporate contracts faster than Meta’s chat‑based approach.

OpenAI Delays Release of Latest Model Over Safety Concerns

OpenAI announced a postponement of its upcoming AI model, codenamed Astra, to conduct additional safety testing. The company said the model must meet evolving safety standards before a broad rollout, though it did not disclose the specific risks prompting the delay. The decision arrives amid heightened global scrutiny of AI ethics and regulation, and follows OpenAI’s public apology for mishandling a security breach that exposed an Australian government website. In response, OpenAI is reviewing internal security protocols and communication practices. Industry analysts view the delay as a cautious move that could reshape how AI firms balance rapid innovation with rigorous safety assurances, potentially influencing future product timelines and regulatory expectations.

💡 The hold‑up forces the sector to reckon with safety as a launch prerequisite, not an afterthought, nudging competitors toward tighter risk controls.
