Cboe Global Markets posted a monthly average daily volume (ADV) of 22 million options contracts in May 2026, the highest in the exchange's history. The record comes as traders increasingly embrace round-the-clock markets and more complex derivative strategies.
What drove the volume
The surge reflects a broader industry push toward 24/7 trading, which lets investors react to news and economic data in real time, even outside traditional U.S. market hours. Cboe has expanded its overnight trading sessions over the past year, and the May numbers suggest that liquidity is following. Options on indexes and single stocks both contributed to the tally, though the exchange didn't break out the mix.
Impact on revenue and market dynamics
Higher transaction volumes mean higher clearing and execution fees for Cboe. While the company hasn't released earnings for May yet, analysts expect a notable bump in its derivatives segment. The record also signals that market participants are using options not just for hedging but for directional bets and income generation — a trend that has been building since the pandemic-era retail boom. For the broader market, deeper options liquidity can reduce bid-ask spreads and make hedging cheaper for institutional players.
What the record means for 24/7 trading
Cboe's May milestone adds weight to the argument that demand for nonstop trading is real, not just a niche. Competing exchanges like Nasdaq and NYSE have also dabbled in after-hours derivatives, but Cboe is the first to push a full daily calendar. The question now is whether the exchange can sustain this pace through the slower summer months and into fall, or if May was an outlier driven by a cluster of macro events like Fed meetings or corporate earnings.
