Sparta Legend

What is Sparta Legend?

The NLRB ruled after the election that Red Rock took steps to prevent a fair union vote, and Red Rock sued in response, although the ruling was upheld by the US Court of Appeals for the District of Columbia last month. After the court denied a rehearing request on 6 August, it also subsequently denied Station’s request for a stay pending SCOTUS relief on 24 August.

Red Rock may still petition SCOTUS to hear the case, and the court could still choose to do so, but in the meantime the casino must comply with the NLRB ruling. The ruling requires the casino to recognise and bargain with the union upon request, post employee rights notices and other measures.

“The NLRB decision overturned the clear vote of Red Rock team members rejecting the Culinary Union,” Station said in a statement. “The decision prevents any company from granting benefits to its employees if it is aware of union interest in unionising the company’s employees and nullifies the Red Rock team members’ vote to be union-free, all because Station Casinos treated its team members too well.”

“Just better margins,” he says of that decision. “I think it’s more defendable. It’s the area that fewer people can do well. So I think it’s more defendable margin, more ability to get long-term contracts and beneficial positions.”

Singles can be profitable, but parlay pricing requires the market maker to calculate the correlations between multiple outcomes and respond dynamically to individual requests. It is a skill set built over years in the sharper regions of the existing sports betting ecosystem.

Other estimates are considerably higher, illustrating how difficult the market is to measure. As an example, separate research from Gaming Compliance International put the value of unregulated online gambling at $5.9 trillion in wagering value in 2025, while estimating that unregulated operators accounted for 78% of global online gaming GGR.

Another report, commisisoned by Euromat, estimates that Europe’s black market has sustained a compound annual growth rate of 18% between 2019 and 2026, and will be worth up to €13 billion by the end of the year.

For enforcement authorities, however, the challenge is not simply estimating its size. It is keeping track of an ecosystem that can continually change domains, infrastructure and acquisition channels. That is where Madsen sees Trace2Trace fitting in.
