Coinbase US500 futures reached a $100 million milestone, giving the exchange an early test of whether a crypto-native trading mechanism can travel into regulated US equity markets.
Key facts
- Coinbase product-page, roughly 15 hours after Armstrong posted, showed $7.22 million in 24-hour volume and $3.01 million in open interest
- At the preserved Aug. 28 reading, $7.22 million in 24-hour volume was about 2.4 times the $3.01 million in open interest
- The chart attached to Armstrong’s Aug. 28 post tracked trailing 24-hour matched volume after US500 began trading on Aug. 17
- Coinbase’s consumer page uses “24/7” language elsewhere, but the listed session and the CFTC filing establish a Sunday-to-Friday market
Summary
01 US500 logged a launch-week $104 million volume peak, then showed $7.22 million in a later 24-hour snapshot. 02 Coinbase’s US500 uses hourly funding inside a five-year, cash-settled futures contract tied to MarketVector’s index. 03 The real demand test is sustained volume, open interest, and liquidity across ordinary sessions—not one launch spike. The chart attached to Armstrong’s Aug. 28 post tracked trailing 24-hour matched volume after US500 began trading on Aug. 17.
