Bloomberg Stock Movers
2026-10-21 · Hosted by — · Bloomberg / iHeartMedia
Executive Summary
Bloomberg's Stock Movers Report covered a busy morning of earnings reactions. SpaceX shares rose on third-quarter revenue that came in well above expectations, driven by growth in its AI and satellite internet businesses, while Elon Musk's comments about a potential SpaceX-Tesla merger — which he described as possibly the largest corporate merger ever — added further lift to both stocks in pre-market trading.
Key Stories & Changes
Third-quarter revenue came in "much better than expected," driven by growth in the AI business and the satellite internet (Starlink) business
Elon Musk said SpaceX could combine with Tesla in what would be the largest-ever corporate merger, creating a conglomerate spanning electric cars, data centers, and space rockets
Musk acknowledged it may be difficult to secure shareholder support, so the deal is "not really a done deal yet"
Tesla shares also received a lift in pre-market trading on the merger speculation
2. Super Micro Computer Rallies on Strong Results
Super Micro reported strong earnings tied to continued AI server demand
The company remains under a legal cloud from a probe accusing a co-founder and two others of illegally diverting billions of dollars of product to China in violation of US law
Super Micro has not been formally charged in the case, and today's earnings strength is overshadowing that overhang for now
3. Netflix Falls Further on Slowing Growth
NFLX: Netflix — Continued decline — Reported slowest sales growth in three years; guided to a fourth consecutive quarter of slowing growth, blamed on the advertising business
Netflix has gone months without a major hit film or TV show and is struggling to stand out amid intensifying streaming competition
A reported bid for Warner Bros. is adding further uncertainty about the company's forward growth strategy
4. AT&T Falls Despite Beating on Revenue and Profit
AT&T reported revenue and profit ahead of expectations and raised its guidance, yet shares fell
The decline was attributed to fewer wireless phone subscriber additions than expected, amid an intensifying price war for mobile customers
Analysts flagged that SpaceX's planned entry into the wireless/mobile sector could further pressure AT&T's margins, forcing heavier spending to retain and attract customers
Trends Identified
1. AI Infrastructure Earnings Continue to Outperform
Both SpaceX and Super Micro posted strong results tied directly to AI infrastructure demand — satellite/compute buildout for SpaceX and AI server hardware for Super Micro — reinforcing that despite broader market jitters about an AI slowdown, the underlying infrastructure spending cycle remains robust enough to drive earnings beats.
2. Streaming and Telecom Incumbents Face a Common Threat: New Entrants
Netflix's struggles stem from increased competition and content gaps, while AT&T's subscriber miss is compounded by the looming threat of SpaceX entering the wireless market. Both stories illustrate how established consumer-facing incumbents are facing structural competitive pressure from both existing rivals and new, well-capitalized entrants. ---
Sentiment Analysis
Overall Market Sentiment: Mixed, AI-Infrastructure Positive
AI infrastructure names (SpaceX, Super Micro) are being rewarded, while consumer-facing incumbents (Netflix, AT&T) face selling pressure despite otherwise solid headline results in AT&T's case.
Risk Factors Highlighted
SpaceX-Tesla merger shareholder approval uncertainty: Musk himself flagged that securing shareholder support is not guaranteed.
Super Micro legal overhang: Ongoing probe into alleged illegal technology diversion to China remains unresolved.
Netflix content and engagement gap: No major hit in months, compounded by a reported Warner Bros. bid complicating the growth narrative.
AT&T competitive and margin pressure: Intensifying mobile price war, with SpaceX's potential entry posing an additional structural threat.
