Cboe Launches Mini S&P 500 Binary Options in New Prediction Market

Cboe is entering the prediction market with accessible Mini S&P 500 binary options. Rolling it out through major brokers could help speed up this fast-growing market even more.

Key Takeaways

• Cboe Global Markets launched its first product through Cboe Predicts: binary options on the Mini-S&P 500 Index.
• The XSPBW and XSPBX contracts are now available through Interactive Brokers; Charles Schwab and other brokers will follow later.
• Cboe wants to use this prediction market to meet demand for short-term options and keep expanding its lineup.

Cboe Global Markets has launched its first product under Cboe Predicts, a new suite of prediction markets. It involves binary options on the Mini-S&P 500 Index (XSP), which are currently available through Interactive Brokers. Charles Schwab will also offer access soon, followed by other brokers.

New Prediction Market With Mini-S&P 500 Contracts

The Mini-S&P 500 binary options trade under the symbols XSPBW and XSPBX. This product makes it easy to bet on where the index will close: a "yes" position pays out $100 (€88) if the index closes at or above a set level, while a "no" position pays the same amount if it closes below that level. At one-tenth the size of the regular S&P 500 Index (SPX), it is an accessible option for retail investors.

Cboe clears these products through leading retail brokers and provides central clearing through the Options Clearing Corporation (OCC). According to JJ Kinahan, Head of Retail Expansion at Cboe, the growing demand for options with very short expirations, such as zero-days-to-expiration (0DTE), plays a big role in this expansion. Rob Hocking, Global Head of Derivatives, said Cboe is aiming to raise the bar for market integrity, product design, and investor protection with this move.

Why It Matters for the Market and What Comes Next

This launch puts Cboe in the fast-growing prediction market space, where platforms like Polymarket and Kalshi are also active. Interest in this segment is rising, and open interest recently hit a record $1.48 billion (€1.3 billion). Cboe plans to keep expanding its offering by adding vertical spreads through the patent-pending Quoted Spread Book.

Cboe Global Markets, founded in 1973 as the Chicago Board Options Exchange, has a long history of building exchange products and is known for helping introduce the VIX volatility index. With Cboe Predicts, the company is now moving into a new area, using its experience and infrastructure to help make prediction markets more professional.

What Does This Mean for European Investors?

Even though Cboe Predicts is currently being offered through U.S. brokers, the launch of accessible Mini-S&P 500 binary options could point to broader trends in short-term options trading and prediction markets. European investors may also run into this in the future, especially given the growing interest in these products and the desire of major market players to expand their offerings.
