“We spotted nine Polymarket accounts, all connected, who made, collectively,$2.4 million betting almost exclusively on U.S. military operations,” says Nicolas Vaiman, co-founder of the small data analytics firm Bubblemaps. “And now here's the crazy part: 98% win rate.” cbsn.ws/4wwp0T7

Chase says: “if you get arrested for insider trading, we accept you taking that risk for yourself” Does the firm not have any consequence when its employees insider trade? @matt_levine
SCOOP: JPMorgan Chase employees are allowed to trade prediction markets, even when the bank itself is the subject of the market. New employee guidance, circulated to staff this spring, emphasizes that “you must be cautious” when using prediction markets and warns against insider trading. It doesn’t require employees to pre-clear prediction market trading activity with the firm. $JPM has advised employees to “limit your participation in prediction markets involving JPMorgan Chase” as “others could perceive this as a misuse of information,” according to a copy of the guidance @ungarino and I viewed. “Think carefully before participating in markets related to the financial sector,” JPMorgan’s guidance says, listing examples such as stock prices, earnings, regulatory filings, leadership changes, interest rates, foreign-exchange rates, economic policy, mergers and acquisitions, and product launches. It adds that employees should never use confidential or material, nonpublic information to transact. Bank watchdogs in the U.S. such as the Federal Reserve and the Office of the Comptroller of the Currency don’t currently mandate banks to monitor prediction markets. A JPMorgan spokesman declined to comment on how the bank plans to enforce its guidance or what it means to limit participation in markets where JPMorgan is involved. The guidance from JPMorgan, the largest U.S. bank, is notable given how little is publicly known about companies’ prediction-market policies. Last week, the credit-ratings firm KBRA said in a press release that it would issue a blanket ban on prediction market trading for employees. “KBRA determined that a companywide prohibition is the only appropriate course consistent with its responsibilities to the market,” the company said.

This is an email I sent earlier today to all employees at Coinbase: Team, Today I’ve made the difficult decision to reduce the size of Coinbase by ~14%. I want to walk you through why we're doing this now, what it means for those affected, and how this positions us for the future. Why now Two forces are converging at the same time. We need to be front footed to respond to both. First, the market. Coinbase is well-capitalized, has diversified revenue streams, and is well-positioned to weather any storm. Crypto is also on the verge of the next wave of adoption, with stablecoins, prediction markets, tokenization, and more taking off. However, our business is still volatile from quarter to quarter. While we've managed through that cyclicality many times before and come out stronger on the other side, we’re currently in a down market and need to adjust our cost structure now so that we emerge from this period leaner, faster, and more efficient for our next phase of growth. Second, AI is changing how we work. Over the past year, I’ve watched engineers use AI to ship in days what used to take a team weeks. Non-technical teams are now shipping production code and many of our workflows are being automated. The pace of what's possible with a small, focused team has changed dramatically, and it's accelerating every day. All of this has led us to an inflection point, not just for Coinbase, but for every company. The biggest risk now is not taking action. We are adjusting early and deliberately to rebuild Coinbase to be lean, fast, and AI-native. We need to return to the speed and focus of our startup founding, with AI at our core. What this means To get there, we are not just reducing headcount and cutting costs, we’re fundamentally changing how we operate: rebuilding Coinbase as an intelligence, with humans around the edge aligning it. What does this mean in practice? - Fewer layers, faster decisions: We are flattening our org structure to 5 layers max below CEO/COO. Layers slow things down and create coordination tax. The future is small, high context teams that can move quickly. Leaders will own much more, with as many as 15+ direct reports. Fewer layers also means a leaner cost structure that is built to perform through all market cycles. - No pure managers: Every leader at Coinbase must also be a strong and active individual contributor. Managers should be like player-coaches, getting their hands dirty alongside their teams. - AI-native pods: We’ll be concentrating around AI-native talent who can manage fleets of agents to drive outsized impact. We’ll also be experimenting with reduced pod sizes, including “one person teams” with engineers, designers, and product managers all in one role. In short: AI is bringing a profound shift in how companies operate, and we’re reshaping Coinbase to lead in this new era. This is a new way of working, and we need to leverage AI across every facet of our jobs. To those who are affected I know there are real people behind these decisions — talented colleagues who have poured themselves into this company and our mission. To those of you who will be leaving: thank you. You’ve helped build Coinbase into what it is today, and I am sincerely grateful for everything you've done. All impacted team members will receive an email to their personal account in the next hour with more information, and an invitation to meet with an HRBP and a senior leader in your organization. Coinbase system access has been removed today. I know this feels sudden and harsh, but it is the only responsible choice given our duty to protect customer information. To those affected, we will be providing a comprehensive package to support you through this transition. US employees will receive a minimum of 16 weeks base pay (plus 2 weeks per year worked), their next equity vest, and 6 months of COBRA. Employees on a work visa will get extra transition support. Those outside of the US will receive similar support, based on local factors and subject to any consultation requirements. Coinbase prides itself on talent density. Our employees are among the most talented people in the world, and I have no doubt that your skills and experience will be highly sought after as you pursue your next chapters. How we move forward To the team that is staying, I know this is a difficult day. We’re saying goodbye to colleagues and friends you've been in the trenches with. But here’s what I want you to know as we move forward together: Over the past 13 years, we have weathered four crypto winters, gone public, and built the most trusted platform in our industry. We’ve made it this far by making hard decisions and by always staying focused on our mission. This time will be no different – nothing has changed about the long term outlook of our company or industry. And most importantly, our mission has never been more important for the world. Increasing economic freedom requires a new financial system, and we’re building it. The Coinbase that emerges from this will be more capable than ever to achieve our mission. Brian

We looked into Polymarket's US launch and why its rollout has been slower than it anticipated. The company has lately suffered turnover in senior ranks, with top compliance officers, head of infrastructure, chief information security officer leaving. Most surprisingly, its US CEO is occupied with his other businesses, helping launch more than 300 prop trading firms. Polymarket has now overhauled its top ranks, including hiring a new US leader. Meanwhile its waitlist for US customers has grown to 1.3 million people Story by @MichaelRoddan and me: theinformation.com/articles/… @theinformation

Oh this is gonna be a disaster. Do any halfway decent CEX/ramps exist in the US? I actually kinda liked the Coinbase UX, at least last year
