Congrats @skupor!
Thank you to @realDonaldTrump for the opportunity to serve this great country. Our future as a nation is incredibly bright, and I am humbled to be able to play a small part in helping ensure this path to further greatness!
With the GENIUS Act celebration done, builders already want to know what's next. The answer is CLARITY – crypto market structure legislation – which also got overwhelming bipartisan support in the House last week. Here's everything you need to get caught up on CLARITY:
🇺🇸 @MiebachMichael/@Mastercard, @Brian_Armstrong/@Coinbase, @BHorowitz/@a16z, @PaoloArdoino/@Tether_to, @DavidLRipley/@KrakenFX, @Tyler & @Cameron/@Gemini, @jerallaire/@Circle, and @vladtenev/@RobinhoodApp all agree: Trump signing the GENIUS Act is huge for crypto and finance.
The GENIUS Act is getting signed today, bringing clear rules of the road for stablecoins. Here's why stablecoins are better money, how they're better for people and businesses, and the mental models you can use to understand them. My master thread on stablecoins. 👇

The House just made history by passing major legislation on stablecoins (GENIUS Act) and market structure (CLARITY Act) in an overwhelmingly bipartisan way. This is a huge moment for crypto and for all Americans. We’re very close to having comprehensive, proactive rules in place…
For 50 years, pessimists have been wrong. In this interview, The Rational Optimist author @mattwridley walks us through the miracle of human advancement, from lighting a room to transforming entire economies. This is the story you’ve never been told about how the modern world…

Big thanks to @SenatorTimScott, @SenLummis, @BoHines, and @DavidSacks for your leadership. Getting comprehensive crypto market structure legislation passed has been sorely needed for years. We’re incredibly supportive of this effort to make it happen by Sept 30. American…
JUST IN: 🇺🇸 Sen. Tim Scott sets the Digital Asset Market Structure timeline, Sen. Lummis agrees and details progress toward deadline: "I want to set a timeline of seeing the Market Structure completed by the end of September."
This is the right move. Happy to join our Little Tech partners to support Senator @tedcruz’s effort. The U.S. can’t win the AI race if Little Tech is buried under 50 different rulebooks.
In order for the U.S. to win the AI race with China, Little Tech cannot be restricted by a patchwork of state regulations. We support @SenTedCruz's temporary pause on state AI regulation so startups can focus on building, not bureaucracy. Read more: americaninnovatorsnetwork.com/ain-calls-on-s…
