Broadcom Swings on AI Doubts; SpaceX Spectrum Deal Hits AST
Broadcom fell about 2.1% in an AI selloff despite TSMC's record quarter, while AST SpaceMobile dropped 13.7% after SpaceX won Grain's spectrum licenses.
This update is a roundup of same-day reporting from the linked sources below, with editorial context from the CPJ Stock Desk.
Broadcom’s AI story is pulling in two directions this week, with a rally earlier in October followed by a pullback. Separately, SpaceX’s spectrum purchase knocked AST SpaceMobile sharply lower and put analyst coverage of SpaceX shares in focus.
Key points
- Broadcom (AVGO) rose 3.7% on October 6 after Marvell’s investor day, according to Insider Monkey.
- The stock then fell around 2.1% as AI-related selling outweighed TSMC’s record quarterly revenue, per Economic Times.
- AST SpaceMobile fell to $49.13 after SpaceX agreed to buy Grain’s 800 MHz licenses, FinanceFeeds reports.
- Erste Group started coverage of SpaceX (NASDAQ:SPCX) with a hold rating, per American Banking News.
Why is Broadcom volatile when AI demand looks strong?
The headline from Insider Monkey is that Broadcom’s AI revenue is tripling while the stock has lagged. The piece frames the question as whether investors should buy the dip. The summary available to us does not give the underlying revenue figures, so we cannot verify the tripling claim beyond that article’s framing.
The price action has been choppy. Shares jumped 3.7% on October 6, helped by Marvell’s investor day, which suggests the market reads custom AI silicon news across companies. Then, per the Economic Times roundup (citing GuruFocus, TradingView and Barron’s), Broadcom slipped about 2.1% as selling across AI stocks outweighed TSMC’s record quarterly revenue. The explanation offered is that investors remain concerned about elevated expectations for AI growth.
The takeaway is that strong supplier data is not guaranteeing gains. When expectations are high, good news can be absorbed without a rally, and sector-wide selling can drag down individual names regardless of their own fundamentals.
What did SpaceX’s spectrum deal do to AST SpaceMobile?
AST SpaceMobile extended its slide to about 13.7% and traded at $49.13 after SpaceX agreed to buy Grain’s 800 MHz licenses, spectrum that AST had reportedly eyed. FinanceFeeds notes analysts now point to AST’s $550M Ligado deal as its path to spectrum.
Not every analyst reads the news as purely negative. According to Asianet Newsable, citing TheFly, Berenberg analyst Michael Filatov believes SpaceX’s move could sharpen its strategic distinction from AST, and the headline calls AST a natural satellite partner for carriers. That is one analyst’s view, and the available summary does not detail the reasoning in full.
The market reaction and the analyst commentary point in different directions. A double-digit drop shows investors priced in a competitive threat first. Whether the partner-for-carriers thesis holds depends on how carriers respond, which none of today’s sources address.
What is the SpaceX coverage picture?
Erste Group began coverage of SpaceX on Thursday with a hold rating, according to MarketBeat Ratings as relayed by American Banking News. The report also says other firms have recently issued notes, including Mizuho assuming coverage, though the excerpt gives no further details.
Elon Musk, meanwhile, posted on X that SpaceX could one day be worth upward of $12 quadrillion, about 5,500 times its current valuation, per Business Insider. That is a long-range statement from the company’s founder, not a forecast backed by analysis, and it sits next to a cautious hold rating from Erste.
Zoho co-founder Sridhar Vembu responded to Musk on X, saying Indian startups are advancing low-cost rockets, a claim reported by The Hawk. It is opinion, and no evidence of commercial competition appears in the source. Separately, Times Internet’s Satyan Gajwani said at the ET Startup Awards that Skyroot’s Vikram-1 launch made India the third country with a private company reaching space, and that India’s AI progress has been slower than it should be, according to Economic Times.
What else is worth watching?
OpenAI denied firing three former safety researchers over their warnings, saying the dismissals stemmed from a breach of trust, Economic Times reports. The company also said it plans to contract independent safety assessors. The researchers’ account and OpenAI’s differ, and the sources do not resolve it. For investors in AI exposure, it is a governance and reputational item rather than a financial one for now.
