At the same time, prediction market operators are facing regulatory tussles in the US. State regulators are moving to shut down the firms under gambling laws. The companies say their contracts should be regulated at the federal level as derivatives.
However, the sector has grown substantially despite such disputes. Bernstein predicted in April that annual prediction market volume could reach $1 trillion by 2030. The research estimated volume was around $51 billion in 2025 and could grow to around $240 billion in 2026.
The partnership with Yahoo Finance wraps up as prediction markets push for broader distribution across financial media, sports, and entertainment platforms. For Polymarket, the loss of the Yahoo Finance hub is one distribution channel, but other partnerships remain intact.

Before Patrick Mahomes laced up his cleats for his 2026-2027 NFL regular-season debut, US prediction markets had already cleared a historic benchmark for the opening week of the season.
Two operators alone – Kalshi and Polymarket – topped the combined $1 billion mark in NFL trading activity over the first six days of Week 1, according to numerous measures this week. During the period, Kalshi recorded NFL volume of $983.4 million, according to DeFi Rate, earning the pole position by a large margin. Mahomes and the Kansas City Chiefs thrashed the Denver Broncos 31-10 on Monday Night Football, capping the largest week for prediction markets ever.
Even before the primetime matchup in Kansas City, it became abundantly clear that the industry would shatter previous marks for weekly activity. The AFC West showdown bolstered the already robust totals. Overall, volume for the week hit a record $15.9 billion, according to Bank of America, up 16% from a week earlier.

“ARGN was created because problem gambling is becoming a bigger issue across Africa and most responsible gambling efforts still happen within individual countries,” Akolade tells iGB. “While many organisations are doing great work, there has been limited opportunity to learn from each other, share research, or work together on common challenges.
“We felt there was a gap for a continent-wide network that could connect organisations, encourage collaboration, and help build a stronger collective voice on player protection. ARGN is not here to replace national organisations or regulators. Its purpose is to support and strengthen the work already being done by bringing people and organisations together.”
But while the ARGN intends to enhance collaboration between stakeholders across the continent, Akolade asserts the aim is to promote “common principles rather than identical regulations”.
