Quick answer

Available, on a federal license.

As of April 2026, an eligible California adult can trade ForecastEx event contracts, accessed through Interactive Brokers. ForecastEx holds no California gaming license and does not need one. It is a Commodity Futures Trading Commission registered Designated Contract Market and clearing organization, which lets eligible United States residents, including those in California, trade its listed event contracts. Its footing is a full federal registration rather than the conditional relief some other venues rely on.

The nuance worth knowing

California is a useful place to explain the federal distinction, because the state has no legal online sports betting. Voters rejected Propositions 26 and 27 in November 2022, so commercial sportsbooks do not operate there. ForecastEx is not a sportsbook. It is a federally registered event contract exchange launched in 2024 as an Interactive Brokers company, and its authorization rests on federal commodities law, not California gaming approval. That is why a federally regulated event contract market can reach a California resident even where state authorized sports betting does not exist. Confirm your eligibility on the platform.

What this means in California

Why a federal exchange reaches California.

ForecastEx is a Commodity Futures Trading Commission registered Designated Contract Market and Derivatives Clearing Organization. It launched in 2024 as an Interactive Brokers company, and eligible United States residents reach its markets through an Interactive Brokers account rather than a separate venue. Because the registration is federal, it is not granted or withheld state by state.

That federal footing is the heart of why ForecastEx reaches California. A Designated Contract Market is authorized under federal commodities law to list event contracts across the country, so a California resident does not need a state gaming license or a state specific approval to trade them. This matters in California in particular, because the state has no legal online sports betting after Propositions 26 and 27 failed at the ballot in November 2022. A federally regulated event contract market and a state authorized sportsbook are different things on different legal tracks.

The contracts are straightforward. Each ForecastEx contract is a yes or no claim about a future event, drawn from categories such as economics and climate, priced between one cent and ninety nine cents, and settling at one dollar or zero once the outcome is known. Per ForecastEx, the platform charges one cent per contract as of April 2026, with that fee built into the price so the cost is visible up front. Always confirm the current fee and contract list on the platform before trading.

The honest caveat in California is about scope and eligibility rather than legality. ForecastEx lists a defined set of event contracts, not a sportsbook menu, and access runs through Interactive Brokers, which applies its own account and eligibility checks. Availability can also be limited for particular products. As of April 2026 eligible California adults can trade ForecastEx event contracts on a federal footing, and the list below sets out federally regulated venues a California resident can look at, subject to age and eligibility checks.
