iGaming market weekly report | May 25–31, 2026
European regulated markets led the upside. Turkey +36.7% — the week’s largest absolute move — rebounded after the prior week’s –25.2% enforcement-driven dip, confirming that underlying betting demand was suppressed. Spain +24.8% saw demand shift when the regulator blocked prediction markets on May 26. France and Hungary posted a +22.2% and +20.1% WoW growth respectively because of the Champions League final on May 30, with Budapest hosting the marquee fixture for the first time.
Declines reflected event hangover and active suppression. Colombia –29.0% extended its contraction as domestic Primera A fixtures failed to generate equivalent matchday gravity to halt the decline. Tanzania –20.6% faced ongoing regulatory friction after government threats against non-compliant operators created access barriers. Haiti –23.0% and Republic of the Congo –22.5% marked mean-reversion after prior-week spikes with no sustaining catalyst, while Ecuador –17.6% showed baseline compression with no clear in-window trigger.
Top gainers
Turkey +36.7%. Users’ interest grew sharply after the prior week’s –25.2% enforcement-driven dip, with the Paymix-3 probe coverage concluding and normal betting behaviour rebounded.
Spain +24.8%. On May 26, the regulator blocked Polymarket and Kalshi which don’t have licences in this country. As a result, Spanish bettors were forced to search alternative ways to access prediction markets or look for their competitors available in the country.
France +22.2%. 30th May was a notable day in France because of the Champions League’s final, where PSG beat Arsenal. This major football event led not only to a spike in bettors’ activity, but also to massive riots on Paris’ streets.
Hungary +20.1%. There was an increased gambling activity in the country because of the Champions League final, which Budapest hosted for the first time.
Botswana +18.8%. No clear country-specific trigger surfaced.
Top decliners
Colombia –29.0%. Primera A entered a dead week between the completed semifinals and the upcoming final legs (June 3 and 9), leaving the market without meaningful fixtures to sustain player demand.
Haiti –23.0%. With no major domestic sports calendar event or policy shift detected, this marks a second consecutive week of significant contraction, unwinding the prior month’s elevated baseline.
Republic of the Congo –22.5%. Following a prior-week spike that had no readily identifiable trigger, the market is returning to its mean. No new catalyst emerged to arrest the decline.
Tanzania –20.6%. Government threatened actions against non-compliant betting operators created ongoing friction, with players’ interest declining as users encountered access barriers or brands reduced promotional visibility. The decline reflects active regulatory pressure rather than organic demand decay.
Ecuador –17.6%. No clear trigger surfaced within the reporting period.
Market spotlight: Turkey | +36.7%
Turkey posted the week’s largest absolute movement, rising +36.7% WoW after declining –25.2% the prior week. The reversal occurred as coverage of the Paymix-3 enforcement probe concluded within the reporting window, allowing normal betting-related behaviour to resume without the suppressive effect of ongoing investigative headlines.
The mechanism is mean-reversion in a high-engagement market with structural demand. Turkey’s illegal betting market is estimated at $10B CEB according to Blask data, placing the country at the third place out of 134 currently tracked countries. When operational friction eases, users rapidly return to search channels to compare odds, access platforms, and engage with live content — without requiring new acquisition hooks or promotional incentives.
Regional snapshot
Europe
Regulated markets led gains, with Spain +24.8% and France +22.2% outperforming on policy enforcement and Champions League final event gravity. Hungary +20.1% benefited from hosting the final for the first time.
Africa
Divergent signals emerged. Botswana +18.8% posted a technical bounce from a compressed baseline. Conversely, Tanzania –20.6% and Republic of the Congo –22.5% reflected active regulatory pressure and mean-reversion, respectively. The region’s split underscores the importance of jurisdiction-specific compliance monitoring and calendar-aware planning.
Next week watchlist
Turkey — Regulatory headlines
New updates on the Paymix-3 probe in early June could trigger users’ interest, followed by a rapid return to baseline.
Spain — Unlicensed platform blocks
The May 26 shutdown of offshore prediction markets led to bettors searching VPNs to access Polymarket and Kalshi. In early June, Blask Index can stabilize because players would manage to access prediction markets.
Compliance enforcement in Tanzania
Mid-May government warnings to unlicensed betting sites may convert into active blocks or penalties in early June.
