> S&P 500 0DTE options averaged a record $2.3 trillion in daily notional volume in Q2 2026, while U.S. approval covered one Bitcoin-linked futures listing.

A comparison of Bitcoin (BTC) perpetual futures with same-day S&P 500 options highlights a key difference for leveraged traders: about 92% of expiration-day SPX trading uses capped-risk structures.

“0DTE” means an option traded on its expiration day. The 92% figure applies to S&P 500 Index (SPX) options; it does not measure Bitcoin options or the broader options market. Most SPX 0DTE option-selling activity takes place in defined-risk spreads.

Perpetual futures have a linear payoff: their value moves with the underlying price, so leverage magnifies gains and losses as that price changes. Options have convex payoffs. An option buyer’s maximum loss is the premium paid, while a defined-risk spread sets a maximum loss in advance.

The capped-risk share describes how SPX 0DTE positions are structured, not how losses compare between Bitcoin and index markets. It is not a statistic about Bitcoin option trading.

SPX 0DTE options averaged a record $2.3 trillion in daily notional volume during the second quarter of 2026, more than 60% of typical SPX options volume. Those figures describe index options and are not a same-period comparison with Bitcoin perpetual futures.

In a modeled scenario for April 21, 2026, the S&P 500 fell 0.94% intraday. Equal-notional positions had modeled returns of 9.4% for a 10x-leveraged short perpetual, 404% for an at-the-money SPX 0DTE put and 617% for an out-of-the-money put. The results apply to that scenario and do not establish a Bitcoin-perpetual return.

The U.S. regulatory backdrop includes a separate listing decision. On May 29, 2026, the Commodity Futures Trading Commission (CFTC) approved KalshiEX, LLC’s BTCPERP contract for listing as a futures contract. The contract references Bitcoin’s spot price, and the approval applies to that listing alone.
