Excited to announce that @travisv has joined Polymarket as Chief Growth Officer. From being TK's growth lead at Uber, to CRO of Yammer under Sacks, to being founder and CEO of Bird (responsible for both my love of Paris and a couple bloody chins) When it comes to growing marketplaces, nobody does it better. This time with software instead of hardware. Welcome to the team.

Some personal news - Polymarket has acquired Craft Agents, and part of the Craft team is joining Polymarket. I'll be leading Product Engineering, with the goal of building one of the best product and design engineering teams in the world. I'm incredibly excited for what's next.

Today we're launching the largest guaranteed NFL Survivor contest in history, with @Polymarket: $21,000,000 up for grabs. Why try something this crazy? Well, it all started 32 years ago, when I was 6 years old, helping my dad make his Survivor picks...

Today is the 6 year anniversary of when I launched Polymarket. I’m truly grateful to be able to work on something that means so much to me. It’s been awe-inspiring to see the world catch up with this crazy idea called “information markets”. Yet there still remains a long ways to go For those curious about my headspace when starting the company, this thread is a nostalgic artifact.

we're growing our product team at Polymarket work with @shayne_coplan and I on the future of prediction markets and ship crazy zero to one ideas to millions of users Email dustin@polymarket.com with your best work

I stress tested Polymarket's freshly upgraded** order system with a 400k market trade on No for a US invasion of Iran. Order went through quicker than before, and no part of it failed^^. We're officially BACK, I think. And good luck to me on that position lol. I think this should be 15%, not 33%. **Polymarket migrated all of the USDC to their own stablecoin pUSD a few days ago, and upgraded their matching engine/order books at the same time (and added fees). The cool part is you can see exactly the tokenholder metrics at any given time -- -- currently 330 million minted tokens, each worth $1, with nearly 400,000 funded users. ^^Polymarket had been dealing with spoofed orders for a little while now, getting worse in the past few months. If you saw, for instance, a 50k order in some random market, and you tired to match it, often the villain races you to cancel that order on-chain before the tx fully completes. As you can imagine, this was a pernicious exploit that drove people insane. But it's now fixed!

The release everyone was waiting for is now live. Ghost fills dropped from a peak of 30% to 0.17% with the rollout, and will continue trending toward 0% throughout the day. We know this issue was hurting everyone's experience and we're truly sorry for that but it should now be night and day. This was a significant core protocol change and we're incredibly proud of the whole team for executing it. We'll keep improving our systems, step by step, until we're the best exchange in the world.

This is my 3rd week as VP of Engineering DeFi at @Polymarket , and I'm going to be straight: the traction @Polymarket has seen has massively outpaced our infrastructure, and we haven't done nearly enough to scale to keep up. I hear you, and fixing this is our entire focus. We're a major company now, and we need to engineer like one. Here's exactly what we're doing: - Onchain data latency. We're working on making this near-instant so the experience is incredible. - Chain migration. We need more block space, cheaper gas and much smaller block times so settlement is instant. - Transactions are getting cancelled. We understand this is one of the most frustrating issues right now, and we have a complete fix coming very soon. - Massive focus on the website to make it faster, more responsive, and with better UX. - We added observability everywhere. Proper alerting so we catch issues ourselves, market makers should not be the ones telling us something is down. That's been unacceptable, and we know it. - E2e tests throughout, starting with the CLOB, so issues get caught in CI before anything ships. - CLOBv2 is not a rewrite. It won't improve performance or stability on its own; it's an upgrade that unlocks us to move fast right after. We'll do better with communication next time. - We are rebuilding the CLOB from the ground up. Most important thing we're doing. Without it, we can't be the best DeFi exchange in the world. We know it, we're on it, it's mission critical. - Unified TypeScript SDK for all APIs, which is shipping soon. - Unified API. One WS connection for everything, with a schema that's actually readable. - New Polymarket contract in the works that unlocks things that are simply impossible on the current protocol. - New hires: Head of QA Automation, Head of Dev Tooling, Head of Internal Tooling, Head of Data Engineering. - Smaller, dedicated teams. Fewer focus points per person, clearer ownership. People do what they're good at and are accountable for it. - Working closely with customer support to give them real debugging tools so any user issue gets properly diagnosed, not lost. - Proper communication with marketing and market makers so everyone knows what's coming and when, and MM can submit feature requests with a clear path to get them into engineering and shipped. - Working with 4 security teams daily to ensure we're super secure and that funds are always safe. - Perps incoming. Brand new contracts and a backend built from scratch in Rust. We're proud of this one. - A lot of other fixes are running in parallel right now. Starting next Friday, I will be posting weekly engineering updates. I joined because I genuinely believe in what @Polymarket is trying to do. @shayne_coplan built this so the world has somewhere to go to find out what's actually going to happen, not what the media thinks, not what a pundit says, but what thousands of people are willing to put money on. But right now, our engineering isn't living up to that. We've let people down, and I'm not going to dress that up. I came here to fix it, and that's exactly what we're going to do. The next few months are going to speak for themselves. Stay with us.

Our team is stunned. We gave Claude Opus 4.6 by @AnthropicAI $10k to trade on @Polymarket. It’s now has an account value of $70,614.59. This is a new era of model performance in trading and predicting outcomes in the face of uncertainty. @predictionbench

Grateful the DOJ officially acknowledged Polymarket's cooperation on this case. Noise aside, the reality is we work proactively with all relevant authorities on any suspicious activity on our marketplace. We flagged this, referred it, and cooperated throughout the process. This happens constantly behind the scenes, despite what many are led to believe. The transparency afforded by onchain markets makes global compliance more effective than ever. Every trade is public, permanent, and auditable. Bad actors leave a trail. As with any fast growing new space, we're adapting and improving as we go. We appreciate the government's willingness to collaborate, learn, and engage with us to bring justice. More to come.
