Cboe (CBOE) binary options return tests Kalshi and Polymarket

Cboe Global Markets (CBOE) gained 0.48 per cent to $257.11 on Tuesday after the exchange operator said it was bringing back binary options on the Mini-S&P 500. The relaunch revives a contract type Cboe last listed more than a decade ago, at a moment when Kalshi and Polymarket have pushed event markets into mainstream trading.

The move pulls prediction-style trading further into listed-exchange infrastructure. Bloomberg reported that Cboe is targeting the same demand for outcome-based trades that helped zero-days-to-expiration options grow to about 30 per cent of all options volume, citing Bloomberg Intelligence. For exchanges, the question is who controls the next retail-to-institutional derivatives product after 0DTE.

Cboe is trying to separate the new contracts from the old yes-or-no binaries. The company said the contracts can offer partial payouts through a “plus” structure, giving traders a way to define risk with more gradation than a simple win-or-lose event bet. That pitch puts the product closer to listed options tools traders already know, rather than to offshore or crypto-native venues.

There is a long gap in the product history. Cboe first listed binary options on the S&P 500 and VIX in 2008. The last SPX contract expired in January 2015, and the last VIX binary expired in August 2017, according to the company’s announcement. The relaunch lands in a market now shaped by 0DTE options, mobile trading and a larger appetite for short-dated views.

In a March Reuters report, managing director JJ Kinahan said customer appetite had kept moving toward shorter-dated, event-driven trades.

“Real-world opinions aren’t always binary, and investors shouldn’t be confined to a yes-or-no framework.”

On Tuesday, Bloomberg quoted Kinahan saying the exchange had seen continued customer demand for shorter-dated, outcome-based trading after the success of SPX 0DTE options. Cboe is taking an existing retail habit and putting it inside a listed, centrally cleared venue.

A listed-exchange answer

The competitive field sharpened last week. Reuters reported that Charles Schwab was working with Cboe to enter prediction markets, while Reuters reported in March that Nasdaq had separately sought SEC approval for prediction-market style options on a major stock index. Exchange groups and broker partners are treating event contracts as a category they may need to distribute, rather than a fringe product left to startup venues.

Kalshi and Polymarket proved there was consumer demand for contracts tied to elections, economic releases and other real-world outcomes. Cboe’s route runs through broker pipes, clearing systems and market makers that already service listed derivatives. If that model works, incumbents get a path to distribute the category at scale, and standalone platforms have a harder time owning it outright.

Regulation remains unsettled. Reuters reported on June 10 that the Commodity Futures Trading Commission was preparing new rules for the industry, even as states started to push back on the category. NPR reported in May that Minnesota became the first state to ban prediction markets, a reminder that growth does not settle whether the contracts look more like betting, derivatives or both.

Liquidity providers are moving too. The Block reported this month that Galaxy Digital opened over-the-counter prediction-market trading for institutions after a $10 million Kalshi trade, and The Block reported in May that Wintermute was extending trading infrastructure into the sector. Cboe’s launch is still an exchange story, but the capital and plumbing around event contracts are no longer confined to one corner of the market.

For now, the stock reaction was modest. The larger read-through is Cboe’s attempt to make the next phase of prediction-style trading happen inside listed infrastructure, where exchange rules, broker access and clearing arrangements can compete directly with Kalshi, Polymarket and newer venues built around short-dated outcomes.
