British traders have been locked out for years, and the Polymarket UK ban is finally getting a second look. On October 6, 2026, the Financial Conduct Authority’s markets chief, Simon Walls, confirmed that the regulator has held talks with prediction-market operators about possible UK entry. Nothing has actually changed yet. The ban is still active, but the conversation itself is new.
What the ban actually covers
The FCA banned the sale of binary options to retail consumers back in April 2019. A binary option pays out one of two fixed amounts depending on whether an event happens. Polymarket and Kalshi contracts settle the same way: a share is worth either $1 or $0 once a market resolves.
The 2019 ban wasn’t aimed at prediction markets specifically; it was a response to a wave of aggressive marketing by offshore binary-options brokers, many of which weren’t authorized in the UK at all, combined with research at the time showing that the large majority of retail clients lost money trading these products. The FCA’s logic was that the payout structure itself encouraged short-term, all-or-nothing speculation with a built-in house edge, which made it a poor fit for retail investors regardless of which firm was selling it. That framing is why the regulator didn’t need new legislation to catch Polymarket and Kalshi; it just needed to decide the contracts fit the existing definition.
In its 2026 perimeter report, the FCA said the financial prediction-market products it reviewed fit its definition of binary options. That keeps them under the 2019 prohibition. The regulator added that the ban still made sense given how speculative these contracts are and the risk of harm to retail users, while leaving the door open for future review.
There’s a second layer on top of that. Markets tied to sports or political outcomes, rather than financial or weather events, fall under the UK Gambling Commission instead of the FCA. Neither Polymarket nor Kalshi holds a Gambling Commission license, so those contracts are blocked for a separate reason entirely. A trader in London can’t currently get access to either category through the front door, no matter which regulator’s rules changed first.
What UK users can and can’t do right now
Right now, Polymarket treats UK IP addresses as close-only. Someone who already holds a position can exit it, but they can’t open a new trade. Kalshi applies similar geofencing. Both platforms are visible and browsable from the UK; placing a new bet is what’s blocked.
This is enforced at the IP level, not through identity verification. The platforms don’t check a user’s passport or billing address before blocking a trade; they check where the connection is coming from, which is a much blunter instrument. That’s exactly why it’s porous — and why a VPN defeats it so easily, at least from a technical standpoint, even though it doesn’t defeat the terms-of-service violation that comes with doing it. Some UK residents get around this with a VPN. That’s a breach of both platforms’ terms of service, and accounts caught doing it risk suspension or frozen funds. We’ve covered how Polymarket’s geo-blocking works for other restricted regions, and the mechanics are the same here: IP detection, not identity checks, decides who gets turned away.
Why the FCA is reconsidering now
The main driver is enforcement reality. British consumers are already using these platforms through VPNs, and a ban that pushes activity offshore gives the regulator less visibility than licensing it would. The Times first reported in September that the FCA was in early discussions with operators about easing the rule, and Walls’ comments in October were the first on-the-record acknowledgment that talks are happening.
That’s a long way from a policy change. The FCA’s public position, as written in its perimeter report, still backs the ban. Walls described the conversations as exploratory, not a signal that a reversal is coming. Any shift would likely take the form of a formal consultation, which in UK financial regulation typically runs for months before a rule changes.
Context matters here too. Polymarket and Kalshi have spent much of 2026 fighting the same “gambling” label in US courts and state capitals, an argument we detailed in our look at Polymarket’s legal strategy. Both companies also face active litigation in Spain and France over unlicensed gambling claims. A friendlier UK regulator would be a meaningful counterweight to that pressure, which is likely part of why both platforms have been engaging with the FCA rather than ignoring it.
It’s also worth noting the contrast with how Kalshi is treated in its home market. In the US, Kalshi’s contracts are regulated by the Commodity Futures Trading Commission as derivatives, not classified as gambling products. That framing has been central to Kalshi’s argument against state regulators trying to shut down its sports-linked contracts. If the FCA’s talks move toward treating prediction markets as a financial-instrument category rather than a binary-options or gambling product, that would echo the CFTC’s approach — though nothing in the perimeter report suggests that’s the direction being discussed, and the FCA has given no indication it’s considering a new product category rather than simply revisiting the existing ban.
What would need to happen for Polymarket to go live in the UK
Two separate approvals would be required, not one. First, the FCA would need to either lift the binary options ban for these products or carve out an exemption specific to prediction markets. Second, for sports and political contracts, Polymarket or Kalshi would need an actual Gambling Commission license, the same kind UK bookmakers hold.
Getting both at once is unlikely to happen quickly. A realistic path looks more like a phased opening: financial and weather-linked contracts first if the FCA moves, with sports and political markets trailing behind once a gambling license is secured. That mirrors how Kalshi’s US expansion has worked, where different contract categories have cleared regulatory hurdles on different timelines.
Even the financial-side approval alone follows a predictable sequence in UK regulation. The FCA would need to publish a consultation paper setting out the proposed change and inviting industry and public comment, typically for a window of several weeks to a few months. Only after reviewing that feedback would it issue a policy statement confirming final rules, usually followed by an implementation period before firms can actually operate under the new terms. Start to finish, that cycle has historically taken the better part of a year for comparable FCA rule changes, which is a useful benchmark for how long “talks are happening” is likely to take to turn into “the ban is lifted.”
The bottom line for UK traders
Nothing opens today. UK accounts remain close-only, and VPN access remains against the rules and risky for anyone holding meaningful balances. The near-term value in this story is that it confirms real talks are underway, with a named FCA official now on record about them.
For traders waiting on legal access, the signal to watch isn’t a tweet or a headline — it’s a formal FCA consultation paper, which is the actual mechanism through which this ban could change. Until that document is published, and until Polymarket or Kalshi separately secures a Gambling Commission license for sports and political markets, the current rules stand exactly as they did in 2019.
