SECONDSENSE Beta ▲11At its core, the $350B resale industry is a messy, unstructured data problem. Resale isn’t a single market — it’s an extremely fragmented ecosystem of global marketplaces (The RealReal, Poshmark, Etsy, eBay, Fashionphile, etc.) and a long tail of independent resellers, social media merchants, and vintage/consignment shops. On both the consumer and enterprise sides, the biggest pain points stem from a lack of unified product schemas and inconsistent condition nomenclature and evaluation standards.

I built a web page that aggregates data about data center buildup, sovereign fund investments into AI and bottlenecks. The objective is to predict AI race cooldown by looking at a potential decrease of activity involving these elements. The website looks at the quarterly forms from the 5 biggest hyperscalers and adds their CapEx into the mix, calculating a composite index in the end showing how likely it is for the AI race to slow down. Enjoy!

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.

Would love feedback on the product, data accuracy, and any ideas for what you'd want to see next.
