Cboe Predicts binary options on the Mini S&P 500 Index (XSP) are now live, giving retail traders a yes-or-no bet on where the index closes, structured as listed security options rather than the CFTC-regulated event contracts used by platforms such as Kalshi and Polymarket.
The contracts trade under two ticker symbols: XSPBW for PM-settled expirations and XSPBX for AM-settled expirations. Each pays out $100 if the trader’s directional call is correct at expiry, or zero if not, per the Cboe IR press release. Settlement for the PM-settled contract is calculated at one-tenth of the official S&P 500 closing price as reported by Standard & Poor’s, per the Cboe FAQ document.
The contracts are European-style, meaning they cannot be exercised before expiry. Regular trading hours run from 8:30 a.m. to 3:15 p.m., according to the Cboe contract specifications. There is no Lead Market Maker programme at launch, which places liquidity provision squarely on the broader market-maker community from day one.
How Cboe Predicts binary options sit inside the existing regulatory stack
The clearing structure is what separates these products from the event-contract space most crypto-native traders will recognise. The XSP binary options are centrally cleared by the Options Clearing Corporation (OCC) and operate under the same regulatory and surveillance framework as all U.S.-listed options, according to Finance Magnates. That means they are securities, not commodity interests, keeping them well outside the contested CFTC-vs-states jurisdictional fight that has followed Polymarket and Kalshi.
For institutional desks, this is less about novelty and more about product architecture. The binary payout structure removes the Greeks-management overhead of vanilla options: there is no delta to hedge continuously, no vega exposure to manage. Entry and exit are straightforward. The trade-off is that the $100 maximum payout is fixed, capping upside on a correct call.
Cboe’s JJ Kinahan, Head of Retail Expansion and Alternative Investment Products, framed the launch in the context of demand flowing from the existing 0DTE SPX options franchise: ‘Cboe’s S&P 500 options suite has long provided traders with flexibility to define their outcomes through traditional options strategies. With Cboe Predicts, we are expanding that choice by offering simple “yes-or-no” payout event contracts, supported by dedicated educational resources designed to help customers participate more confidently and responsibly.’
Cboe has also opened a prediction markets education hub through The Options Institute alongside the platform launch. No LMM programme means traders will want to check spreads carefully in early sessions before liquidity depth is established.
Distribution and competition in the event-contract space
Interactive Brokers carries the contracts at launch. Charles Schwab has announced plans to add access in the coming months. Robinhood and Coinbase have both introduced their own event-based products in the past year, though none sit inside the OCC-cleared listed-options framework Cboe is using.
The broader competitive picture is getting crowded. The New York Times reported on 24 June 2026, citing two employees familiar with the project, that Meta has dispatched a small team to build a standalone prediction markets app called Arena. Insiders characterised the effort as experimental but a top priority for Mark Zuckerberg. The app would initially run on a points-based system, with monetary wagering potentially added later, and would operate independently from Facebook, Instagram, WhatsApp, and Messenger. Meta’s family of apps reported 3.56 billion daily active users as of March 2026, giving any distribution push from the company a reach that no incumbent prediction market operator can match.
For Cboe, the more immediate question is whether SPX 0DTE traders migrate part of their activity into the binary format, or whether the product attracts a genuinely new cohort of retail participants who found the Greeks-based options world inaccessible. Early spread data once Interactive Brokers flow is visible on-screen will be the first indicator worth watching.
