  • Ken Griffin Says AI Is 'Almost Certainly' in a Bubble—And Compares GPUs to Airline Seats

    Citadel founder Ken Griffin said on Oct. 20 that investors are 'almost certainly' in an AI bubble, though he isn't telling them to dump AI stocks and argued that companies surviving bubbles often lead markets for decades. He compared GPUs to airline seats, warning that a chip glut could cause prices to collapse, as fiber-optic cable prices did after the telecom overbuild around 2000. Corporate buyers are increasingly weighing premium models from OpenAI and Anthropic against cheaper open-source alternatives, which strains the labs' spending. Griffin also said AI agents cut some of Citadel's high-level research from weeks to a couple of hours. Earlier, hedge fund Situational Awareness sold most of its public stock portfolio to Citadel on July 30 at roughly a 10% discount, after its value reportedly fell about 67% in July.

  • Ken Griffin: There Are “Almost Certainly Bubbles” in AI Right Now

    Citadel founder and CEO Ken Griffin said on October 20, 2026, at the firm's Future of Global Markets Conference in New York that investors are 'almost certainly' in an AI bubble. He argued that radical economic change is generally tied to bubbles, and that the companies that survive become market leaders for decades. He also warned that corporate America has been uneven in extracting value from AI models, and said agentic tools cut some Citadel research from 6-8 weeks to 2-3 hours. NVIDIA ended at $216.47 and QQQ slid 0.10%, a muted market reaction.

  • Billionaire Ken Griffin Says We May Be in a Bubble. Here’s What History Says Happens Next.

    Billionaire Citadel founder Ken Griffin told Bloomberg that the AI market is 'almost certainly' in a bubble, and the article notes that Alphabet, Amazon, Microsoft and Meta aim to spend more than $700 billion on infrastructure this year, fueling investor doubts about returns. It points out that the S&P 500 has gained nearly 100% since the start of 2023 and that the Shiller CAPE ratio suggests stocks are near a peak. Comparing with the dot-com bubble of 2000, the author argues the crash looks small in the long-term chart, and Amazon fell from about $5 a share to under $1 before trading above $260 today. The author says the market may decline in coming weeks or months, but argues it has historically recovered and that patience with quality stocks may be rewarded over time.

  • Tech Stock Sell-Off: This Could Be the Most Powerful Reason to Buy Bonds Right Now

    The tech-heavy Nasdaq-100 fell about 6.5% between Oct. 6 and Oct. 16 in an AI stock sell-off, with the steepest declines in semiconductor stocks and companies supplying AI data center build-outs. Investors are worried about whether AI companies are borrowing too much and whether hundreds of billions of dollars in AI spending will pay off. Unlike 2022, when stocks and bonds fell together, the 10-year U.S. Treasury yield has declined since both levels peaked on Oct. 5, meaning bond prices rose, which the article sees as a sign of a flight to safety. According to Bloomberg, a J.P. Morgan strategist said government bonds can help rebalance portfolios and offer a genuine way to diversify concentration risk in equities. The article notes the Vanguard Total Bond Market ETF (BND) holds 11,434 bonds at a 0.03% expense ratio.

  • Trump is pushing a massive AI buildout. His own voters are wary of what comes with it

    President Trump frames the AI race with China as a national-security priority and backs a major buildout of data centers and power infrastructure. A CNBC All-America survey of 1,000 registered voters (conducted Oct. 14-18) finds that while about 55% of MAGA supporters want AI development to continue alongside congressional regulation, only 29% would back a data center within 10 miles of their home and 40% would oppose one. Across the electorate, 63% oppose a nearby AI data center and 13% support one, with 80% of Democrats opposed. When asked their top concern if Republicans keep Congress, 18% of voters cited failure to regulate AI and data centers. Trump has suggested developers pay host communities a “dividend” and generate their own power.

  • Major US housing overhaul clears White House review — boomers have $13.8T in real estate wealth at stake

    The 21st Century ROAD to Housing Act, which became law in July 2026, will restrict institutional investors controlling at least 350 single-family homes from buying additional properties starting Jan. 7, 2027, without requiring them to sell existing homes. Baby boomers hold an estimated $13.8 trillion in residential real estate wealth, according to Realtor.com, more than one-third of the country's housing wealth despite making up about 18% of the population. The White House completed its review of proposed Treasury Department regulations on Oct. 9, but the rules are not yet finalized and their timing is unclear. The article notes nearly 77% of homes on the market are beyond the reach of middle-income earners, and inflation-adjusted home prices hit an all-time high in 2025, above the 2006 peak. For older Americans considering downsizing, improved affordability could be welcome news, while those staying in their homes may see limited immediate impact.

  • Nvidia's role as AI financier faces first big test as neoclouds take market hit

    Nvidia's role as an AI financier faces its first major stress test as credit markets tighten for key partners. As of its July filing, the company had $36 billion in off-balance-sheet AI cloud agreements, or backstops, for neoclouds, plus a guarantee of up to $105 billion for chips, land and power at a proposed 10-gigawatt OpenAI data center in Ohio. Most of these deals require payment only if project participants default. Shares of CoreWeave, Nebius and IREN, all cash-burning companies in Nvidia's portfolio, are down at least 30% this month, CoreWeave's credit default swap spread has soared past 11%, and Nvidia has just finished a third straight down week, off 7.6% in October. CEO Jensen Huang says neocloud demand is “off the charts,” while David Trainer of New Constructs warns of trouble if compute demand falls short of expectations.

  • Caterpillar Is Quietly Becoming an AI Stock. Here's the Segment Growing 72% That Proves It.

    Caterpillar's second-quarter revenue rose 24% from a year earlier and earnings per share jumped 73%, with the power and energy segment growing fastest. Retail sales of power generation equipment climbed 72%, which CEO Joseph Creed attributed to very strong demand for large generator sets and turbines used in data centers. Data centers consumed about 4.9% of U.S. electricity supply in 2025, and their consumption is projected to more than double by 2030. The company's backlog reached a record $72 billion, up 92% over the past year. Wall Street expects third-quarter revenue growth of 17% and earnings of $7.03 per share, up 42%, and the author says he wouldn't be surprised if the company beats those estimates.

  • President Donald Trump Pledged Not to Touch Social Security, but He's Indirectly Dug a $169 Billion Hole for America's Top Retirement Program

    About 55 million retired-worker beneficiaries rely on Social Security, and Gallup surveys show up to 90% of retirees depend on it in some capacity. The 2026 Trustees Report projects the OASI trust fund will exhaust its reserves by the fourth quarter of 2032, and estimates benefit cuts of 22% may be needed in six years. The Big, Beautiful Bill includes temporary tax breaks for 2025 through 2028, and the Office of the Actuary estimates the law will increase trust fund costs by $168.6 billion from 2025 through 2034, mainly because less income is subject to the 12.4% payroll tax. The article argues this is relatively small compared with the $29.3 trillion long-term unfunded obligation through 2100, which mainly stems from ongoing demographic shifts.

  • Better Buy: Solana vs. XRP

    The article compares XRP and Solana, two cryptocurrencies running on high-throughput blockchains after a recent rebound. XRP, the fifth-largest cryptocurrency with a market cap of nearly $82 billion, is tied to Ripple's activity and its RLUSD stablecoin, and is said to natively scale to 1,500 TPS, though critics question its decentralization. Solana, the seventh-largest with a $61 billion market cap, is described as the fastest major blockchain, surpassing 100,000 TPS in a network stress test, and has over $16 billion in circulating stablecoin supply. The author does not consider either a poor investment, but gives Solana the edge for its greater network activity, higher TPS and stronger stablecoin position.

  • SpaceX Shares Surge as Elon Musk Makes Huge Revenue Prediction. Is the Stock Still a Buy?

    SpaceX (SPCX) shares rose after Elon Musk predicted annual recurring revenue (ARR) of between $500 billion and $1 trillion in 2027, though he acknowledged that meeting all his 2027 targets is not guaranteed. Q3 revenue surged 161% to $14.6 billion, beating the $12.7 billion LSEG consensus, while adjusted EBITDA more than quadrupled to $8.8 billion. The superintelligence (formerly AI) segment led growth, with revenue climbing from $813 million to $7.56 billion, and Starlink connectivity revenue rose 69% while its operating income roughly doubled to $2.4 billion. Growth plans rest on bringing an additional 10 gigawatts of compute online in 2027 and accelerating Starship launches, though the company still needs to fully recover and reuse Starship. The article also flags risks from heavy AI infrastructure capex and the possibility that AI economics weaken if compute supply and demand balance out.
