In finance, one wrong number can erase all the time AI saves. @kepler_ai_hq uses Massive for clean, replayable market data - so every answer is deterministic and traceable to its source. See how they built a data layer for provable AI: massive.com/blog/kepler-buil…

The $25,000 day-trading minimum is gone. As of today, June 4, FINRA's Rule 4210 amendment retires the Pattern Day Trader rule and its $25,000 minimum. So we measured what that barrier actually cost. Using 5-minute bars for every S&P 500 ticker across every May session, we scanned for each 2%+ intraday round trip a day trader could have caught. Our analysis flagged 4,679 potential trade opportunities. Under the old rule, a PDT-restricted trader could have only taken 12 of them, about .3% of the total. Now that the limit is gone, we may see much broader market participation. Dig into the relevant OHLCV data using our aggregates endpoint: massive.com/docs/rest/stocks…

Massive Futures are now generally available. Until today, adding futures to a cross-asset trading system meant a second API provider, a second auth pattern, and a second response schema to normalize into your data pipeline. Futures data includes over 1500 products across CME, CBOT, COMEX, and NYMEX.

We just launched a new European card-spending alternative dataset @massive_com. To get a feel for it, I dug into ten years of daily transactions at Amazon's EU retail sites to find the biggest days 👇

What does it take for a fintech startup to go from Y Combinator to 126 million monthly API requests with a small team? We sat down with @alineainvest_'s co-founder to find out. They built their entire market data layer on Massive from day one, and never had to look back. Full interview is live now.

2025 will be the year of the smartphone. People will start to run their whole lives through their phones, including banking, email, and appointments. Some people will watch entire movies on their phones, and, for many, video-calling will be the norm.
