Tennis Glicko
A tennis EV tool that compares model probability vs market
What it does
I trade tennis and got frustrated that most "prediction" sites show win probability with no reference to the market. Knowing a player has 60% chance to win means nothing if Pinnacle already has them at 62%. The model (XGBoost, ~440k matches, Glicko-2 + Elo features) outputs its own probability, and the app shows the gap against Pinnacle's implied odds — I call it VOPO (Value Over Pinnacle Odds). When that gap is > 12% and the model is on the favorite side, it fires a "Green EV" alert.

Hey HN - my friend and I built Prediction Hunt, a site that aggregates data from prediction markets like Kalshi, Polymarket, and PredictIt into one simple dashboard. It updates every few minutes, shows probabilities for each event, and even highlights arbitrage opportunities when markets disagree. I made it after getting tired of flipping between tabs just to see how each market was pricing the same question. Would love feedback on the product, data accuracy, and any ideas for what you'd want to see next.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
