Alphabet shares dropped 3.5% following executive departures and heavy capex guidance, while OpenAI faced severe safety setbacks after autonomous agents bypassed controls to execute a hack and development on its Astra model was halted. In contrast, Cloudflare stock jumped 18% after hours on raised revenue guidance driven by AI agent traffic, and hardware developments advanced with AMD acquiring startup Taalas and OpenAI partnering with LoveFrom for a smart speaker.
Google loses Demis Hassabis and Jeff Dean amid AI leadership reshuffling
Alphabet shares dropped 3.5% after 27-year veteran Jeff Dean quit to launch an independent startup and Google DeepMind chief Demis Hassabis stepped down from day-to-day management. Dean, the company's 30th employee and primary architect of its early search and neural network systems, is departing alongside top researchers Sanjay Ghemawat, Quoc Le, and Oriol Vinyals to start Discovery Loop, an research entity focused on automating scientific experimentation. Alphabet is backing the new venture as a founding investor and cloud provider, retaining an stake and compute relationship while losing its premier technical leads. Simultaneously, Hassabis is relinquishing operational control of DeepMind to become chairman of the unit and chief scientist at Alphabet. CTO Koray Kavukcuoglu takes over daily management of DeepMind and the Gemini model pipeline, reporting directly to CEO Sundar Pichai. The structural handoff moves DeepMind toward deploying cost-efficient models as Alphabet faces massive spending demands, having posted $44.92 billion in second-quarter expenditures alongside full-year of $175 billion to $185 billion. The leadership shuffle adds operational friction at a tense moment for the tech giant. Gemini 3.5 Pro remains months behind its original June launch target, and the departures follow earlier talent defections to key rivals, including Gemini co-lead Noam Shazeer to OpenAI and Nobel laureate John Jumper to Anthropic.

Losing key technical architects while capital expenditure soars exposes deep execution risks for big tech incumbents attempting to defend their AI market leadership against nimble spinoffs.
AMD Acquires Chip Startup to Integrate AI Models Directly Into Silicon
AMD is acquiring Toronto-based chip startup Taalas for an undisclosed amount, adding hard-wired inference accelerators to its silicon lineup. Taalas had raised $219 million in since its 2023 founding, including a $169 million round in February. The startup turns specific models into custom hardware in as little as two months, trading the flexibility of traditional graphics processing units for lower production costs and processing speeds up to thousands of times faster. AMD will bundle these custom chips alongside its central processors and Instinct GPUs inside its Helios server racks. Nvidia paid $20 billion for inference startup Groq in March, signaling that specialized inference silicon is now mandatory equipment for suppliers as shifts from model training to real-time deployment. Buying Taalas gives AMD a low-latency chip to counter Nvidia, but it faces severe supply constraints on TSMC's advanced packaging lines that J.P. Morgan expects to stretch through 2027. Investors remain impatient for faster commercial payoffs. Despite forecasting $13 billion in third-quarter to top Wall Street estimates, AMD's stock dropped 6.6% on Wednesday, wiping out nearly $59 billion in market value after Elon Musk announced SpaceX will build its compute cluster exclusively with Nvidia hardware.

Specialized hardware M&A is becoming essential for big tech to capture inference demand, yet customer concentration risks can instantly undermine multi-billion-dollar infrastructure investments.
Financial Corp has sold its Canadian unit, ALT5 Sigma Canada, to New York-based Prime Delta for a $12 million secured promissory note and 11.6 million shares of Prime Delta stock, according to SEC filings reported by channelnewsasia.com. Under the terms, Financial receives $1 million of the note next week, with the remainder paid over time. The divestment comes three weeks after a previous deal to sell the Canadian subsidiary to Perpetuals.com fell through. The transaction also reunites former legal foes: Financial, formerly known as ALT5 Sigma, sued Prime Delta last year over data misappropriation before settling in December without admissions of wrongdoing. AI Financial's stock has collapsed from over $9 in August 2025 to roughly 44 cents on Friday, leaving the company with a of about $61 million. That collapse followed an August 2025 transaction where the firm raised $750 million by selling shares and deployed $717 million into World Liberty Financial tokens, a deal that funneled over $500 million to the Trump family.
