Blask Data for May 2026 Highlights Bet365's Top Spot in UK iGaming Brand Rankings as Online Casino Shows Resilience

Blask released its latest figures covering May 2026 and the numbers place Bet365 at the head of UK iGaming brand power rankings with a 12.59% share, while Ladbrokes, William Hill and several others follow in close order. The report comes out in late June 2026, giving operators and analysts a fresh snapshot of how individual brands and larger groups performed in the month after the remote gaming duty rose to 40%.

Brand Power Rankings Take Center Stage

Bet365's lead stands out because the metric combines several performance indicators into one Competitive Earning Baseline score, and the company maintained its position even as many competitors recorded month-on-month drops. Ladbrokes and William Hill sit immediately behind, creating a tight cluster at the top that observers say reflects the ongoing concentration of player attention among established names. At the group level Entain and Flutter continue to account for the largest combined shares, underscoring how parent companies with multiple brands capture a substantial portion of overall activity.

Online Casino Growth Defies April Tax Increase

One of the clearest signals in the May 2026 data is the 14.03% month-on-month rise in online casino activity, a result that arrived despite the duty increase implemented in April. Most major brands nevertheless experienced monthly declines across other verticals, which suggests players may have shifted spend toward casino products while overall participation remained steady. The contrast between category growth and brand-level softness points to changing allocation patterns rather than broad expansion or contraction in the market.

Year-on-Year Trends and Tax Context

Continued year-on-year growth for several top brands appears in the same dataset that records the post-tax monthly shifts. Analysts note that the duty change did not produce an immediate across-the-board slowdown; instead the data show selective resilience, particularly in casino, while sports betting and other categories faced steeper monthly headwinds. The pattern suggests that players responded to price increases by reallocating rather than exiting the market entirely, a development that groups such as Entain and Flutter appear positioned to absorb given their diversified brand portfolios.

Market Concentration and Competitive Dynamics

Entain and Flutter's dominance at the group level remains consistent with earlier periods, yet the brand-level rankings reveal that individual operators within those groups must still compete fiercely for position. Bet365's 12.59% share demonstrates how a single well-known brand can outperform larger collections of smaller labels when measured by the blended power metric. The close spacing between the next several brands further illustrates how quickly share can shift if one operator executes a stronger promotional cycle or product update in any given month.

Looking Ahead from June 2026

With the May 2026 numbers now public, operators are examining whether the casino uptick represents a lasting reallocation or a temporary reaction to the duty change. The young demographic profile and the 15% risk indicator together supply additional context for compliance teams that continue to refine responsible-gambling tools. Year-on-year gains among leading brands meanwhile provide a baseline against which future months will be judged as the higher duty rate remains in place.

Conclusion

Blask's May 2026 release supplies a detailed view of brand power, category performance and player composition at a time when the UK iGaming sector is still absorbing the effects of the April tax adjustment. Bet365's leading position, the strong casino growth figure and the continued year-on-year progress for several major operators form the central facts that stakeholders will reference as June 2026 draws to a close and the next reporting cycle begins. The full dataset offers further breakdowns by vertical and demographic slice for those tracking these movements in real time.
