SEC Filing
An SEC filing is a document that a publicly traded company must submit to the U.S. Securities and Exchange Commission. These reports are publicly accessible and one of the most important sources of news about companies like Nvidia, Apple, or OpenAI partners.
In the United States, there is a government agency that oversees stock trading. It is called the Securities and Exchange Commission, or SEC for short. Every company whose shares are traded on a stock exchange there must regularly send documents to this agency. Such documents are called SEC filings. They state how much money the company earned, what risks it sees, and what important events occurred. The underlying idea: anyone who buys a stock is giving the company their money and should therefore know what the situation there really looks like.
Why journalists read the filings first
A company writes its own press releases and usually presents itself in the best light. An SEC filing, by contrast, is a legal document. Anyone who deliberately makes false statements in it risks penalties up to and including prison. That’s why filings contain things a company would otherwise never mention voluntarily.
For the tech industry, these filings have become especially interesting. In the risk sections of major corporations, entire paragraphs about artificial intelligence now appear. Some companies warn there that their search engine could be made obsolete by chatbots. Others write that they are heavily dependent on a single chip supplier. Such sentences are often the most honest assessments a company makes public.
Figures on AI infrastructure also become visible here. If a corporation states that it plans to invest 70 billion dollars in data centers next year, that appears in a filing before it hits the news. This is exactly where many headlines about the AI boom originate.
The most important form types
SEC filings are not freely worded but follow fixed forms with numbers. The annual report is called Form 10-K and is the thickest document, often several hundred pages long. It contains the business report, the audited figures, and a long section on risks. The quarterly form is called 10-Q and is shorter because it only covers three months.
For sudden events, there is Form 8-K. It usually must be filed within four business days. A CEO’s resignation, a major acquisition, or a serious hacking incident all end up in this form. When there was a dispute over OpenAI’s leadership in 2023, observers closely tracked exactly these short-term filings from the companies involved.
A third type does not concern companies but large investors. Anyone managing over 100 million dollars in U.S. stocks must file a Form 13F quarterly. It states which stocks they hold. This lets the public find out whether well-known funds are currently buying or selling chip stocks. All of these documents are stored in a free database called EDGAR, which anyone can search without registering.
SEC filings in news coverage
When a news story begins with phrases like “a mandatory disclosure reveals”, there is almost always a filing behind it. This often involves stock sales by executives, new major shareholders, or warnings about declining revenue. Information about AI chips, supply bottlenecks, or export restrictions to China also frequently comes from such documents.
An important distinction: the SEC is a U.S. agency and is only responsible for the American market. German companies report to BaFin, though similar rules apply there as well. Foreign companies whose shares are traded in New York file a form with the SEC labeled 20-F.
A common misconception is that the SEC reviews the information in advance and certifies it as correct. It does not. It mainly checks whether a filing was submitted and whether the form is correct. Only if suspicion arises does the agency investigate further. The filing is therefore not a seal of quality, but a statement for which the company itself is liable.
