Grogan v IG Index (spread betting, GBP 1.08m losses, vulnerability) (High Court (Business List, Manchester)): Status, Rulings and What It Means for Players

What this case is about

Grogan v IG Index Ltd is a claim in the High Court (Business List, Manchester), reported as [2026] EWHC 1998 (Ch), docket BL-2024-MAN-000058.

Mark Grogan filed it in 2024 against IG Index Ltd. It belongs to the wider group of Gambling Addiction Lawsuits that ask whether a betting firm owed a duty to a customer who could not stop.

Mr. Grogan describes himself as a gambling addict. He lost GBP 1.08m spread betting with IG. He argued that IG broke Financial Conduct Authority (FCA) conduct rules and was negligent.

Who is covered

This is an individual claim, not a class action. It binds the two parties only. The betting period in the record runs from May 2018 to January 2022, with deposits of GBP 1,751,731.37 and losses of GBP 1,082,511.74.

The ruling matters to other players in England and Wales who consider similar claims. Related decisions appear in Gambling Lawsuits in United Kingdom.

Is there a payout?

No payout exists in this case. The High Court dismissed the claim, so the court awarded Mr. Grogan no damages. The record shows no fund, no settlement and no claim process for other players.

What the court decided

On 31 July 2026 HHJ Pearce dismissed the claim. The claims were: breach of FSMA s.138D through COBS 10A (appropriateness) and COBS 2.1.1R (best interests), failure to protect a vulnerable customer, a common law duty of care (Calvert, Quinn v IG Index) and a fiduciary duty.

The court found three things. IG did not breach the appropriateness rules. There was no obvious vulnerability that triggered a duty to intervene. And there is no wider common-law duty beyond the narrow duty recognized in Quinn.

As of 14 November 2026 the case record shows a dismissal and no later step.

Why it matters

Spread betting sits under the Financial Services and Markets Act (FSMA), not the Gambling Act. Even so, the reasoning tracks the two best-known UK duty-of-care decisions, Calvert and Gibson. The result adds a third failed route for customers who blame an operator for their losses.

Questions people ask

How much did Mark Grogan lose?

The record gives deposits of GBP 1,751,731.37 and losses of GBP 1,082,511.74 between May 2018 and January 2022. The court dismissed the claim, so none of that sum was awarded back.

Does the Gambling Act apply to spread betting?

No. Spread betting sits under the Financial Services and Markets Act, not the Gambling Act. That is why Mr. Grogan relied on FCA conduct rules (COBS) as well as negligence.

Did the court find that IG had to stop him betting?

No. HHJ Pearce found no obvious vulnerability that triggered a duty to intervene. The judge also declined to extend the common-law duty beyond the narrow Quinn duty.
