Amazonfounder Jeff Bezoswon't call the top of the AI boom, but he knows exactly what he'd tell someone living off their savings.

Fox News host Bret Baierasked Bezos whether the industry is in a bubble. "It's hard to know," Bezos said in an interview on Oct. 7. "What I do know is the technology is real."

Good Ideas, Bad Ideas, Same Funding Round

Bezos said the trouble is that in these periods "every experiment gets funded, the good ideas and the bad ideas." He added that "in the moment, in all of the tussle of this, it's hard for investors to know the difference between the good ideas and the bad ideas."

Speculators can lose money when enthusiasm runs ahead of results, he said, but the inventions themselves don't disappear. In his view, that dynamic is "tricky for investors" and "good for society."

The Math That Makes The Line Blurry

The numbers show why the call is hard to make. A JPMorgan Chasebasket of 41 AI-linked companies has accounted for roughly 49% of the S&P 500's market value, a concentration not seen for a single theme since the railroads. Nvidia, Apple, Alphabet, Microsoftand Amazon carry heavy index weights on their own.

The five largest hyperscalers are guiding toward roughly $800 billion in 2026 capital spending on AI infrastructure, while the cleanest measures of above-trend AI-related revenue remain a fraction of that. Spending is real and accelerating, but the full payoff is not yet visible.

Own The Whole Market, Skip The Contest

Then Baier asked the practical question. "Would you tell a retiree to own AI stocks today?"

"I would usually tell a retiree to buy the S&P 500," Bezos said.

"Play it safe," Baier replied.

The S&P 500 is the broad, low-cost default that already owns the major AI companies in proportion to their size. Berkshire HathawayChairman Emeritus Warren Buffett and other long-term investors have given the same advice for decades, which is to own the market and skip the stock-picking contest. For a retiree, that is the simplest way to stay invested without trying to separate the good experiments from the bad ones while the tussle is still underway.

Building Wealth Across More Than Just the Market

Building a resilient portfolio means thinking beyond a single asset or market trend. Economic cycles shift, sectors rise and fall, and no one investment performs well in every environment. That's why many investors look to diversify with platforms that provide access to real estate, fixed-income opportunities, precious metals, and even self-directed retirement accounts. By spreading exposure across multiple asset classes, it becomes easier to manage risk, capture steady returns, and create long-term wealth that isn't tied to the fortunes of just one company or industry.

EquityMultiple

For accredited investors looking beyond stocks and bonds, EquityMultiple provides access to vetted commercial real estate deals starting at $5,000 , with only ~5% of opportunities passing their due diligence process.

Arrived

Backed by Jeff Bezos, Arrived Homes makes real estate investing accessible with a low barrier to entry. Investors can buy fractional shares of single-family rentals and vacation homes starting with as little as $100 . This allows everyday investors to diversify into real estate, collect rental income, and build long-term wealth without needing to manage properties directly.

American PowerGen

As artificial intelligence drives a surge in electricity demand, reliable power generation is becoming a critical part of the technology ecosystem. American PowerGen is developing natural gas-fired power plants in Texas, a fast-growing market fueled by AI data centers, manufacturing expansion, and population growth. By advancing projects through permitting, fuel supply, and grid interconnection, the company is positioning itself to help meet rising energy needs while offering investors exposure to the infrastructure supporting the next wave of AI and industrial growth.

Bito

As AI coding tools take on more of the work traditionally done by developers, companies are facing new challenges around code quality, context and the rising cost of AI-powered development. Bito is building software designed to help AI coding agents better understand complex codebases while helping companies control AI development costs. Founded by former PubMatic executives, Bito has raised more than $10 million from institutional and individual investors and is now raising additional capital through a Wefunder offering, giving investors an opportunity to invest in a company targeting an emerging need within the rapidly expanding AI software market.

FarmTogether

Farmland has historically held its value through market volatility and delivered returns uncorrelated to stocks and bonds. For accredited investors, FarmTogether offers direct access to high-quality U.S. farmland starting at $15,000 — fully managed, with no landlord headaches.

Fundrise

Private real estate and private credit can add income and stability to a stock-heavy portfolio. Fundrise offers access to diversified private real estate and credit strategies through an easy-to-use platform, with professionally managed portfolios designed to generate passive income and long-term growth.
