Stablecoins and the GENIUS Act: What the Law Says
Part of the guide: Money for AI agents: spend, save, and Lightning
A stablecoin is a digital coin meant to always be worth one dollar. People use them to move money fast, and AI helpers (called agents) are likely to use them too: a robot that pays a few cents for a service does not want to worry about the price jumping around. So the rules around stablecoins matter a lot for the "agents pay for things" future.
The 10-second version
- The US passed a stablecoin law. The GENIUS Act was signed on July 18, 2025.
- Issuers must back every token. The White House fact sheet says issuers must hold real backing for every coin (100%), in things that are easy to turn into cash, such as cash itself or short-term government IOUs.
- They must show their work. The company has to show what it holds in its vault (its reserves) every month.
- Coin holders go first if the company fails. The fact sheet says if the company goes broke, coin holders get paid before the other people it owes money to.
What we could and could not check
We read the White House fact sheet for the signing date and these three requirements (White House fact sheet). A fact sheet is a summary written by the administration. We tried to open the bill itself on Congress.gov, but the site refused our request, so we have not read the statute text and we cannot vouch for details like redemption timing or who exactly may issue.
We also saw market-size numbers (hundreds of billions of dollars in total) on crypto blogs, but they disagreed with each other by large amounts, so we are not printing a number.
Stablecoin or Bitcoin, for an AI helper?
They solve different jobs.
- A stablecoin is good for pricing. A 2-cent service still costs 2 cents tomorrow.
- Bitcoin is good for keeping value that no company issues. It is not designed to hold steady against the dollar.
- The catch with stablecoins is that a company stands behind each one. The law adds rules about backing and showing the books, but it does not remove that company from the picture.
