Sam Altman, Elon Musk and Dario Amodei want AI slowed as tech stocks tumble. Is your retirement fund overexposed?

Dario Amodei, CEO of Anthropic, a leading pure-play AI company, has expressed concerns about the rapid development of AI models. In a post on his personal website, Amodei suggested that companies should slow down the advancement of AI to allow for the development of safety measures. While he highlighted potential benefits such as the potential to cure most major diseases, he also acknowledged the associated risks, which include loss of control over AI, severe economic disruption, cyberattacks, and bioterrorism.

Amodei's call for a slowdown was echoed by OpenAI CEO Sam Altman and SpaceXAI founder Elon Musk. Altman stated that OpenAI, another major player in the AI space, would not go public in 2026 due to the safety challenges facing the industry. Musk also endorsed the proposal on X, agreeing with Amodei's stance.

Following the calls for a slowdown, AI-linked shares experienced a significant sell-off globally. Nvidia, a key player in AI, saw a 3.4% drop, while SoftBank Group, a major investor in OpenAI, fell nearly 11% in Tokyo. This sell-off exposed an underlying vulnerability within retirement accounts. Many investors may have a significant portion of their savings invested in AI-related companies, even if they did not deliberately purchase AI stocks.

The exposure to AI-linked stocks can be substantial, particularly for those holding S&P 500 index funds. These funds are weighted by market capitalization, giving larger companies greater influence. For example, Nvidia alone represented almost 8% of the State Street SPDR S&P 500 ETF Trust, while Apple and Microsoft accounted for 7.4% and 5.6% respectively.

The 10 largest holdings of the fund accounted for approximately 38% of its value. If an investor had $100,000 in a $100,000 retirement portfolio with 60% invested in an S&P 500 fund, they would indirectly own about $4,800 of Nvidia through that fund alone.

To mitigate this exposure, investors who have time before retirement may decide to maintain substantial stock exposure while shifting new contributions towards a more balanced mix of companies. Even small investments, such as those made through apps like Acorns, can grow over time with minimal effort. Additionally, exploring alternative investment options like gold or real estate can provide diversification and act as a hedge during periods of economic uncertainty.
