We're about to enter a period where not reading or writing becomes as ubiquitous as smoking once was. We can hope people will eventually realize this is bad for them, as they did with smoking. But this is far from certain; the cost may not be as obvious.

Super excited to announce that Lisa Mantil has joined Polymarket to grow our Institutional business. Polymarket is only the second job of Lisa's career. She spent 27 years at @GoldmanSachs rising through the ranks to Partner, where her specialty was understanding what institutional clients needed and building the financial products to deliver it. That's the sauce she's bringing to Polymarket, and we're grateful to have her. If you're interested in taking large size in any event contract relevant to your business or portfolio, DM me or email institutional@polymarket.com. Thank you to Cyril and @DavidSolomon for the intro and recommendation. Onwards.

Video of @craftdocsapp on iPhone Duo. Simulator already works pretty nicely besides the animations. First thing to improve: move the back button to the side. Any idea you would like to see? Thinking about a "reading mode".

Apologies for the radio silence. I joined Polymarket last year and since then I have been heads down building a team and introducing a lot of the core features in social. It's been stupidly fun and very rewarding. Live chat on all events was first and was a little rough around the edges to start, its now become one of the biggest features on the app. I'm excited to share the work we've been doing on Squads, and it doesn't stop there... there is plenty lined up. With that said, I've built an absolute elite team of iOS engineers and I'm looking for more! If you are or know someone who you think is gunna be a great fit please reach out! I'm looking for people with great UIKit experience and a keen eye for craft and the finer details.

We're rolling out squads on the Polymarket app We wanted trading with friends to feel way more native. Now you can spin up a group chat, send picks, and trade together 👬 if you want to try it, join my squad below 👇

Honest post: the Polymarket DeFi CLOB is full of tech debt. It grew fast, got hacked together, and most of the team inherited it that way. Since joining and building out the team, we have scaled it 10x and made it 3x faster, but it’s not enough; the core foundations of how it’s been built are wrong in almost every way. You try to fix one thing, and another thing goes wrong; the conclusion now is that the codebase can’t be saved long-term. The exchange is the heart of Polymarket; everything runs through it. If we want to be the best exchange in the world, it must be fast, stable, and scalable. We can’t keep patching the old one, where these core foundations are generally missing throughout, so we’re rewriting it from scratch in Rust. Early numbers: 10-20x faster on p99 than today, 200,000 orders per second (15x what we have now, with room to reach 400,000+), and stability under load. This will put us faster than most exchanges, including CEXs. Building it in Rust gives us memory safety with no garbage collector. No GC means no random pauses and no random latency spikes; the tail latency in the benchmarks is the tail latency you get in production, alongside a strict compiler that enforces correctness up front. Data races and memory corruption (the bugs that take exchanges down) can’t exist in the first place. Polymarket has to take it seriously that we are an exchange; this is people’s money, not a joke. To succeed, we have to fix this; otherwise, we will fail. It’s as simple as that. I joined to build the best software in the world, not to maintain some of the worst, and I will do everything I can to make Polymarket a serious exchange. We are aiming to have the exchange ready sometime in Q4 (mid to end). I'll communicate progress as we go so you all know the status. Breaking changes will be minimal for all integrators and will be communicated in advance. We will maintain the existing CLOB and keep trying to improve it as we build this side by side. We can’t wait to throw away the existing CLOB; we dislike it as much as you all do. Make Polymarket fast, finally.

excited to share that @turfsports_ is joining @Polymarket Turf was built for sports fans to put their predictions on a scoreboard Polymarket brings that same instinct to everything, at world scale and @shayne_coplan + team have the vision and taste to match that ambition

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.

As a builder l would be quite happy if models no longer improve exponentially. Even without further improvements there’s much we could do 10x better - and being able to focus on a problem for more than 3 months could result in some novel ideas on the the ui/product side of things!

Hi everyone, I just open sourced OpenBrand - extract any brand's logos, colors, and assets from just a URL. It's MIT licensed, open source, completely free. Try it out at Why we built this: while building another product, we needed to pull in customers' brand images as custom backgrounds. It felt like a simple enough problem with no open source solution - so we built one.

There's a lot of noise around how "Ai generates buggy software". The truth is writing the code was always 20% of the time. Testing and refining was always 80%. But now as that 20% compresses 10x, we want to compress the 80% as well... That's the mistake.

90% of my time is now spent in Do the plan, screenshots come back (via built-in browser) of the implemented feature, and when needed fully built HTML artifacts for multiple edge cases, light/dark mode etc. Feels so nice...

Great to see same system we've been using at Craft, and being used here as well - 2 colors + 1 accent is all you need when used right. Adding a success+info+error color as optional can add those final touches of everything feeling "just" right. Contrast is a very thoughtful addition!
