Interactive Brokers ForecastTrader review

IBKR ForecastTrader is Interactive Brokers’ front end for forecast contracts listed on ForecastEx, a CFTC-designated contract market. The contracts are yes/no claims on economic releases, rates, climate and political events, settling at $1, and IBKR pays interest on the position value while it is open — which is a genuine structural difference from every other venue here.

The ownership is the thing to understand first, and it is stated in both parties’ own documents. ForecastEx Rule 201: “ForecastEx LLC is a wholly owned subsidiary of IBG LLC.” Interactive Brokers’ FY2025 annual report on Form 10-K describes ForecastTrader as its platform for trading contracts from ForecastEx, “a registered exchange with the Commodity Futures Trading Commission … and our wholly-owned subsidiary”.

So the broker owns the exchange that determines the outcome. That is disclosed rather than hidden, and it is legal, and it is still a concentration of roles that no other venue on this site has.

Rule 311(d) commits the exchange to posting a specification for every listed contract, and unusually the commitment holds up when tested. We requested the full instrument list without an account on 9 September 2026: roughly 11,470 live contracts came back, and every single row carried a populated specification URL, with none missing.

The specifications are specific where it counts. The CPI contract names its source agency and states that “ForecastEx will only consider the initial CPI value from the official release”, which settles the revision question before it can be argued about. Every specification carries a delay clause: if the source agency delays the data, resolution is delayed until it is released.

One disclosure gap is worth naming. Rule 507(a) obliges brokers to hand customers the risk disclosure statement and the rulebook — not the per-contract terms. And IBKR’s own retail FAQ presents settlement as strictly binary and never mentions the Event Review process at all, which matters given the next section.

The criterion most venues make unanswerable is the history of disputed resolutions. ForecastEx answers it. Its notices to members run to 439 entries, of which 83 concern resolution or settlement delays — 40 of those citing the US government shutdown — and eight document the exchange replacing or overriding its own data source.

The notices are specific. One reads: “The Event Review Committee has determined that the correct resolution value for the ULBNA_072226 Contracts is 73.” Another invokes Rule 414 accelerated settlement when no October unemployment rate would be published, resolving the contracts “to the most recent last prices”. In practice that meant binary contracts settling non-binary — the Louisiana primaries closed at $0.50/$0.50 and $0.38/$0.62, which is not an outcome the retail FAQ prepares anyone for.

The process was also applied unevenly. Three temperature markets received an explicit “Event Review Process Initiated” notice; the Louisiana contracts received only a delay notice before being settled at fair value. A separate disciplinary log carries nine filings, one of them against Interactive Brokers LLC itself for executing a transfer without prior approval, fined $1,250.

Determinations are closed to challenge in the rulebook’s own words: the Event Review Committee “has full discretion in resolving the Event Review Process” and its determinations “are final”, with a parallel rule adding “final and not subject to review”.

Arbitration exists under Rule 801(a) and runs under NFA rules, and customers are inside the definition of market participant. But Rule 801(d) lets the exchange’s own Regulatory Oversight Committee decide whether a matter is even appropriate for arbitration, and that decision is also final. The exchange therefore controls the gate to the forum that would review it.

There is also a drafting defect worth knowing about if you ever need to follow the rules through. Rule 415(c) assigns the first-line decision on a data error to a “Change Control Oversight Board” — a body the rulebook never defines, and which the exchange’s own website describes as the committee that approves access to its IT systems. The following subsection tests a different body entirely for the same condition.
