Citadel founder Ken Griffin told the Future of Global Markets Conference in New York that investors are “almost certainly” in an AI bubble. He said many U.S. companies have struggled to extract value from their AI models and are now scrutinizing bills from Anthropic and OpenAI, while Anthropic may put $750 billion toward computing capacity over the next several years. Griffin argued that companies on the other side of a bubble tend to be market leaders for decades. Results from NVIDIA, Microsoft, Amazon and Broadcom still showed strong growth, so suppliers kept posting record numbers. The article also describes how the Situational Awareness fund, heavy in SanDisk and Micron, was forced into a distressed sale to Citadel after margin calls during the AI sell-off, and how Citadel profited by supplying liquidity in the panic.

- Trump's FTC Subpoenas OpenAI and Anthropic. Inside the $500 Billion Threat Faced by Microsoft, Amazon, and Google
The U.S. Federal Trade Commission sent civil subpoenas to OpenAI and Anthropic on Oct. 15 as part of a consumer-protection probe, according to Axios. The demands seek documents on security incidents, safeguarding practices, marketing materials and privacy policies, and the FTC reportedly plans to have top AI executives testify. The combined stakes held by Microsoft, Amazon and Alphabet in the two labs total about $554 billion at recent valuations. The article argues the bigger financial risk lies in how the investigation could affect the price the labs fetch when they go public.

- Anthropic Is Growing 50%, Microsoft Isn't
Anthropic said its revenue rose 50% quarter over quarter to $16.8 billion, and the author estimates its 2027 revenue could exceed $100 billion and its IPO valuation could reach $2 trillion. The author argues this growth puts pressure on public companies whose shares depend on AI, such as Microsoft, whose $3.9 trillion market cap is up only 4% over the past year while the S&P 500 is up 16%. In its latest quarter, Microsoft reported revenue of $90 billion (up 18%) and diluted EPS up 32% to $4.81, but AI revenue was not highlighted separately. According to the article, Microsoft's legacy business is weighing on its valuation, and Alphabet, Meta and Amazon face a similar challenge.
- Famous Billionaire Calls AI a Bubble — But That Is Not What His Money Says
Citadel founder Ken Griffin told Bloomberg at Citadel's Future of Global Markets conference that there are almost certainly bubbles within the current AI boom. He compared GPUs to airline seats, warning that once capacity exceeds demand prices may collapse, similar to the fiber-optic bust around 2000. Yet Citadel's amended 13F for Q2 2026 showed about $8.6 billion in five AI-linked companies, with Amazon its second-largest holding; its Amazon and Microsoft share counts rose 34% and 43%, while Nvidia shares fell about 37%. The filing also disclosed options on Nvidia and Micron that may hedge risk, and it is only a snapshot as of June 30.

- Forget AI Stocks: 2 Cryptocurrencies to Consider Buying Instead
The article argues that the AI boom could cool, while nearly a dozen top cryptocurrencies have risen more than 100% this year. Hyperliquid (HYPE) is up 220% for the year and is estimated to control as much as 70% of the perpetual futures market on decentralized exchanges, but it remains off-limits to U.S. investors, and the Bitwise Hyperliquid ETF (BHYP) has traded since May. Zcash (ZEC) is up 136% year to date with a market cap of about $20 billion, and the Grayscale Zcash ETF (ZCSH) surpassed $1 billion in assets under management within its first 30 days.

Greg Abel became Berkshire Hathaway's CEO at the start of the year and so far has made few major changes, closing some positions formerly managed by Todd Combs while keeping the company culture and most Buffett-era holdings. Apple (AAPL) is Berkshire's largest holding, about 22% of its public equity portfolio, and recently closed above a $5 trillion market cap, becoming only the second company to do so.
