FCA's binary-options ban proves harder to overturn than platforms expected

FCA's binary-options ban faces a dual-regulator wall no platform has cleared

Britain's gambling arbitrage has a structural problem that the FCA's internal review has not yet resolved, and the trading volume projections circulating in Westminster may be the least of it.

The FCA has held talks with trading platforms about potentially lifting the ban on retail access to financial prediction markets — a restriction in place since 2019, when the regulator classified binary options as too speculative for ordinary investors. That classification has not changed. What has changed is the volume of British consumers accessing Kalshi and Polymarket from UK IP addresses, some through VPNs, all outside the protection of UK financial rules.

The FCA's own perimeter report acknowledged the gap and left the door open for further work. That is not a policy change. It is a notation.

Here is the structural problem that the reporting understates: any platform seeking to operate a full-spectrum prediction market in the UK faces two separate regulatory gatekeepers. The FCA governs contracts tied to financial and certain weather events. The Gambling Commission governs everything else — sports, politics, elections. To offer what Kalshi or Polymarket offers, a platform needs both permissions, from two bodies with different mandates, different risk tolerances, and no formal coordination mechanism between them. Neither has indicated it is ready to move. The FCA is in talks. The Gambling Commission has spent the last month suspending operators for AML failings.

The industry's argument to regulators is essentially a leakage argument: millions of British consumers are already using these products; the ban has not stopped participation, it has only removed consumer protection. That argument is not wrong. It has also been true of other banned products that stayed banned for years after the leakage data was submitted.

What the FCA has not resolved publicly is whether it will recategorise prediction contracts based on risk profile rather than product label. Its discussion paper raised the possibility. The difference matters because a recategorisation would require new rulemaking, not just permission for a specific platform. Rulemaking takes time that the leakage data does not buy you.

I do not think the dual-regulator structure resolves within a single review cycle. The more likely near-term outcome is a limited FCA pilot for a narrow category of financial event contracts, probably index or rate-linked, leaving the Gambling Commission's jurisdiction untouched. That is not the market that Kalshi or Polymarket has built. It is a smaller, less liquid version of it, and the platforms that lobbied for the change will spend the next year arguing about the perimeter of the pilot rather than operating inside it.

Bernstein's projection of $240 billion in global prediction market volume this year is the number everyone is reaching for. It is also a global figure being used to justify UK-specific regulatory urgency. The FCA does not regulate Kalshi's US book. What it regulates is the UK consumer's access to it — and the current leakage, however large, does not obligate the FCA to act on any particular timeline.

The Gambling Commission's recent suspensions of Bet St George and BresBet on AML grounds are not directly connected to prediction markets, but they are the operational context inside which any new gambling licence application arrives. A Commission that is tightening AML enforcement on existing operators is not one that fast-tracks novel product categories.
