Apple just delivered the biggest shake-up to its AI efforts since launching Apple Intelligence, replacing chief John Giannandrea with Microsoft and Google veteran Amar Subramanya. The move comes as market momentum stalled yesterday, with crypto's 6% Bitcoin plunge dragging down tech stocks and ending a five-day winning streak across major indexes.
Apple is making its biggest AI leadership bet since the iPhone. The company's decision to replace artificial intelligence chief John Giannandrea with Amar Subramanya - who spent years at both Microsoft and Google - signals how seriously Cupertino is taking criticism that it's fallen behind in the AI race.
The timing isn't coincidental. Industry experts have been warning that Apple Intelligence, launched just last year, lags significantly behind competitors like OpenAI and Google. Subramanya brings deep experience from both companies that are currently leading the generative AI charge, giving Apple a potential edge in catching up.
But Apple wasn't the only tech giant making moves yesterday. Nvidia announced it's taking a massive $2 billion stake in chip design software company Synopsys, calling it a "huge deal" during an appearance on CNBC's Squawk on the Street. CEO Jensen Huang sees the partnership as crucial for accelerating AI engineering work - a sign of how the chip wars are evolving beyond just manufacturing.
The AI developments came as markets hit their first speed bump in days. A brutal 6% slide in Bitcoin - its worst performance since March - sent ripples through risk assets and ended five straight days of gains across the Dow, S&P 500, and Nasdaq. Crypto-related stocks and AI plays both felt the pinch, showing how intertwined these sectors have become in investor minds.
Retail bucked the trend though, with the SPDR S&P Retail ETF pushing its weekly gains above 6% as holiday shopping momentum builds. But that momentum hit a snag for Shopify merchants, who faced hours-long outages on Cyber Monday - one of the year's biggest online shopping days. The platform, which handles over 10% of U.S. e-commerce transactions, saw shares drop nearly 6% as merchants couldn't access point-of-sale systems during peak shopping hours.
Meanwhile, Costco is taking the fight over Trump's tariffs straight to the Supreme Court. The wholesale giant filed suit last week seeking full refunds of tariffs paid this year, joining dozens of other companies betting the court will rule the duties illegal. The urgency stems from a Dec. 15 deadline that could prevent future refunds - even if the tariffs are ultimately struck down.
