🚨 OUT OF PRIVATE BETA 🚨 Today, we are thrilled to officially launch ZEIT Finance Tokenized Vaults on top of Prediction Markets. Reality is now an asset class. Prediction Markets are the fastest, most precise representation of reality. We believe that the "assetization of reality" is the next culture-defining tool in the Web3 space. If you have a conviction, you can now tokenize it. 🧵👇

Today proved just how easy it is to find & charge criminal insider trading when markets are onchain. It's not anonymous — you will be found just like this guy. We appreciate the recognition from SDNY & will continue to work with gov’t authorities to prosecute bad actors.
Last month, we published our enhanced market integrity rules to combat insider trading. When we identified a user trading on classified government information, we referred the matter to the DOJ & cooperated with their investigation. Insider trading has no place on Polymarket. Today's arrest is proof the system works.

Big fan of @ClickHouseDB because: 1. Focus on real-time 2. Fast 3. Cost-efficient 4. Materialized Views reduce need for dbt 5. Query Endpoints spin up quick APIs 6. ClickPipes = out-of-the-box integrations 7. Ease to scale s/o @goldskyio @jefftyling for the recommendation
Like many startups, @Polymarket started with what made sense: Postgres. clickhou.se/3ZmTCqy As their platform took off, the data in Postgres grew, and it naturally became used for everything - transactions, data warehousing, and user-facing analytics. Analytics began to strain Postgres, and limited what questions they could ask. In a couple months, Polymarket's lean data team added ClickHouse alongside Postgres, powering their data warehouse, in-app analytics and public APIs. We chatted with @primo_data about the journey.

Huge reversal in Polymarket's Polish presidential election odds. If this stands, will be major slap in the face to European establishment, where Poland was quietly groomed to be the next Germany

TODAY ⚡️ U.S. court overturns SEC decision to block Grayscale #Bitcoin ETF From the opinion: "The [SEC's] denial of Grayscale’s proposal was arbitrary and capricious because the Commission failed to explain its different treatment of similar products....We therefore grant Grayscale’s petition and vacate the order." bloomberg.com/news/articles/…
