Anthropic wants to raise $100 billion in its IPO, but history shows many big-name debuts fall short of broad market funds. Here's why S&P 500 ETFs often give investors steadier long-term growth.
Investors are watching Anthropic's planned IPO closely. The artificial intelligence company is aiming to raise $100 billion. That would top even SpaceX's recent offering. The size of this target has sparked talk about whether Anthropic could become a new market giant or end up like other hyped IPOs that faded fast.
The record for huge IPOs is mixed. Some companies have grown into leaders. Others have dropped out of sight or been delisted. For investors thinking about chasing the next big thing, the numbers show that broad market index funds have quietly beaten many headline IPOs over time.
Anthropic confidentially filed a draft registration statement with the U.S. SEC on June 1, 2026, but this early step does not mean shares are trading publicly yet.
IPO hype versus market reality
Anthropic's $100 billion IPO target follows SpaceX's record $86.7 billion raise in June. These numbers grab attention, but history gives a warning. The biggest IPO of 2024, Lineage, has dropped 53% since it started trading. Infineon, once the world's largest tech IPO, left the New York Stock Exchange ten years after going public. Even companies that seem too big to fail can run into trouble. Early investors in high-profile IPOs often face wild price swings and letdowns.
For every Visa or Meta Platforms that becomes a household name, there are plenty of companies that never meet their early promise. The lesson is simple: size and hype at launch do not guarantee strong long-term returns.
Why index funds often win
For most investors, a low-cost S&P 500 index fund is a strong alternative to chasing single IPOs. The Vanguard S&P 500 ETF (VOO) has $1.8 trillion in assets and charges just 0.03% in fees. It gives investors a piece of the biggest and most stable U.S. companies. Over the last 20 years, the S&P 500 has averaged an 11.3% annual return. A $10,000 investment would have grown to nearly $85,000, all without having to pick winners among new stocks.
Index funds adjust as the market changes. They add rising companies and drop those that fall behind. Anthropic will not join the S&P 500 right away because of regulatory rules. But investors in broad market funds will get exposure if Anthropic is added to the index later. This approach lowers the risk of betting big on one company's uncertain future.
Anthropic's IPO timetable has slipped from an earlier September/October expectation, with Reuters reporting that marketing is now expected to begin in mid-October at the earliest, and the IPO could be pushed until after the November U.S. midterm elections.
As reported earlier, most ETFs give little or no access to companies like Anthropic before their IPO. Key financial details often stay hidden until after the public debut. This makes it hard for most investors to judge the real risks and rewards of buying at the IPO stage.
Performance data and investor outcomes
S&P Dow Jones Indices reports that the S&P 500's long-term returns have beaten most actively managed U.S. equity funds. In 2023, the S&P 500 returned 24.2% with dividends. Many recent high-profile IPOs have struggled to match or beat the index. Low fees and built-in diversification help explain why index funds are a mainstay in many retirement and brokerage accounts.
Investors should also think about liquidity, trading costs, and the chance of sharp price swings after an IPO. IPO shares can be tough to get at the offering price, and early trading often brings big moves. S&P 500 ETFs, on the other hand, trade all day with tight spreads and deep liquidity. They are easy and cost-effective for most investors to buy and sell.
Understanding the broader investment landscape
The buzz around Anthropic's IPO is easy to understand. But most investors do not need to chase every new listing to get strong long-term results. Index funds let people take part in the growth of leading companies as they rise, while avoiding the risk of getting caught up in IPO hype.
For those new to index investing, it helps to know how these funds work. An S&P 500 ETF holds shares of the 500 largest U.S. public companies, weighted by market value. The fund's lineup changes as companies grow, shrink, or are replaced. This keeps investors tied to the market's top names. Automatic rebalancing is a big reason why index funds have often outperformed many active strategies and single stock picks over time.
