As shown in the chart below, AOI hit $5.575 billion — the previous all-time high was $5.369 billion on February 14. Open interest in this context represents the total value of outstanding bitcoin futures that have yet to be settled.
The data shows that BitMEX, OKEx, Huobi and CME continue to constitute the bulk of the market activity for bitcoin futures. Last week, CME reported an all-time high open interest for its cash-settled bitcoin futures offering, hitting $724 million.
This past weekend also saw heightened volatility around bitcoin and ether, with both currencies experiencing flash crashes on August 2.
