About Crystal Hall

The company committed to a management reshuffle late last year as part of this transition, scrapping the role of deputy CEO after Velipekka Nummikoski was shuffled into a new role.

The operator has made a number of key operational and technology changes during this process, including switching its sportsbook backend from DraftKings to OpenBet. And hiring a number of industry stalwards to lead its competitive business.

Former Scientific Games veteran Chris Armes was appointed as the new executive VP of Gaming Technologies in early August. Armes is set to take up his new role in the autumn of 2026, leading Veikkaus’ technology organisation from its Helsinki headquarters. 

About Crystal Hall

Kesitilwe says the AiA also wants to develop a clearer picture of problem gambling across Africa and use that evidence to support engagement with governments and policymakers.

“We also, from the point of view of the Alliance, intend to do Africa-wide studies around prevalence of problem gambling in different markets, obviously working with regulators and associations,” he says.

Alongside this, the AiA wants to use the lessons from the inaugural week to broaden participation and establish the campaign as a permanent fixture.

What is Crystal Hall?

Kalshi’s compliance department uncovered a series of large trades made by Santos throughout February 2026 involving contracts that would pay out based on whether he attended the State of the Union address on 24 February. 

The exchange reported that Santos then issued public statements regarding his attendance, some deemed false or misleading, that were deliberately aimed at influencing the price of “Yes” or “No” contracts connected to his attendance. 

Kalshi stated that these statements successfully moved market prices and that Santos realised profits totalling $17,839.57 from the trades. After detecting Santos’ trades, Kalshi froze his account then referred the matter to federal authorities, NPR reported.
