Nicely done!

AI doomers say if we build AI we might die. But they have it backwards: 165,000+ people already die every day. Cancer, heart disease, illnesses, car crashes. AI is helping us solve these. Slowing progress doesn't keep us safer, it guarantees more preventable deaths.

The 2024 election proved the importance of the crypto voter. @standwithcrypto is now much bigger, with over 4M members. Crypto voters will remember who stepped up and who didn't.

GM. Having a look at the upgraded @CoinbaseWallet and I’m genuinely impressed. Felt like taking a minute to give them some credit. Night and day difference from what I was using back in December 2025. Prediction markets, cleaner UI, and even the new opening screen feels incredibly sleek. I’m taking a break from trading anything new right now, but when I’m back, I’m going to start using this instead of Fomo. @cobie wen coming on my show

Really can’t thank this group enough - they showed great leadership and spent countless hours working to make CLARITY happen.
All of us in the crypto community owe a massive debt of gratitude to @SenatorTimScott, @JohnBoozman, @SenLummis and @berniemoreno for the extraordinary work they put into CLARITY. They spent countless hours working through extraordinarily difficult issues, listening to stakeholders and colleagues across the aisle, and pushing relentlessly for clear rules that protect consumers while keeping innovation and the future of finance in America. The vote this week was disappointing. But their work was not wasted. They moved the debate enormously and laid the groundwork for the durable market structure the United States still needs. Big thanks to each of them for their leadership, persistence and commitment to getting this right.

Thank you for what you do! It has inspired me on many mornings while exercising at the gym, getting in the right mindset to go crush the day.
Today is the 10 year anniversary of Founders. It’s my life’s work. Thank you for listening.
Here we go again! The WSJ is working on a story blaming Coinbase and me personally for the CLARITY Act not passing. The Journal has repeatedly been hostile to CLARITY in its reporting, regurgitating bank lobby talking points, while I’ve spent years pushing for crypto legislation, but that’s not stopping them from trying to reverse the blame. The boring TLDR: in January I opposed a draft of the bill going into a committee vote, because it needed a lot of work on DeFi, tokenization, CFTC authority, and stablecoin rewards. At the time, the bill had major issues that would have harmed crypto. Support was fractured, and it wasn’t passable. We worked with a number of parties who improved the bill and made it passable. All four of the items I called out were fixed in the draft that then went through the committee about four months later. I'm proud to have done it, and would do it again, because it helped create a better bill. One step of many along the way. The final draft of CLARITY that went to the Senate was great, and I strongly supported it. I'll continue showing up for our customers and pushing for clear rules that treat crypto fairly, even if those who feel threatened by crypto try to plant false stories. It's a shame that the WSJ takes direction from bank lobbyists instead of reporting the truth, but luckily, people are smart enough to see through it these days, and it backfires on them every time.

America can't be the leader in finance without the best products. It's time to bring stock perps onshore.
Single stock perps are coming to America. Coinbase has filed to list the first set of single stock perpetual futures in the US. Building on the progress of our live US perps market, we’re working to bring liquid, 24/5 exposure to individual stocks in the US for the first time.

USDC rewards in even more countries 🇧🇷 Directly on Coinbase.
Onchain rewards shouldn't depend on where you live. Now people in Brazil can put their USDC to work onchain - right from the Coinbase app. Onchain, for everyone.
