Institutional demand for crypto options is accelerating

As Grayscale noted in its 2026 Digital Asset Outlook, digital asset markets are entering an institutional era, with capital inflows and integration with traditional finance increasingly defining price action. Options are central to how that capital expresses itself. Portfolio managers adjusting delta, managing volatility, and constructing defined-risk strategies need options to work - and demand has held up even as spot activity has softened. 

The addition of Bullish's BTC options data to The Block and Laevitas - two platforms used widely for institutional derivatives evaluation -  arrives at a moment of accelerating activity in Bullish's options market. In three weeks, open interest grew by 82% from $3.32 billion on April 2 to a peak of $6.07 billion on April 23 - ranking second globally for BTC options open interest, according to data on the Block. 

The day before, on April 23, Bullish BTC options volume crossed US$1 billion in a single 24-hour window, accounting for approximately 20% of total global BTC options volume. Those figures place Bullish among a small cohort of regulated venues now operating at institutional scale, at a moment when the market has signaled clear and growing demand for crypto options.
