About Black Mamba
There are no SCOTUS-prediction market contracts currently on Kalshi but Polymarket lists a 41% probability that the court will accept an event contract case by 31 December.
A hearing before the Supreme Court would be the culmination of what has been the biggest sports betting-related development since PASPA. Perhaps no other issue has united gaming stakeholders from various companies, tribes, states and regulators.
Beginning with the US presidential elections in November 2024, when prediction markets catapulted into mainstream culture, their rise has been undeniable. Kalshi and Polymarket have seen their valuations balloon to $40 billion and $21 billion, respectively, and the majority of the top US bookmakers have scrambled to expand into the prediction space in various forms, either by building their own exchanges, acquiring existing ones or engaging in market-making.
What is Black Mamba?
In addition, regulated sportsbooks appear to have a vested interested in mitigating the risk of violent threats associated with athlete harassment. Joe Maloney, president of the Sports Betting Alliance, told iGB on Tuesday that its members are investing in tools and partnerships that help identify bad actors and share information with leagues and other stakeholders.
Another proposed action from the leagues centres around the creation of a standardised, cross-operator reporting platform that will allow players, unions and leagues to “securely transmit verified evidence of threats” to state regulators.
Maloney leads an association that features sportsbook powerhouses such as DraftKings, FanDuel, Fanatics and Bet365.
How to play Black Mamba
If Bernstein’s $10 trillion prediction market turnover forecast is realized or exceeded, it’d likely prove significant in revenue terms because the research firm previously estimated that $1 trillion in yearly activity could generate as much as $10.8 billion in revenue for operators.
As has been widely documented, sports event contracts are currently the lifeblood of the prediction market industry, but Bernstein notes that won’t be the case on a permanent basis. In fact, the research firm estimates that sports derivatives’ share of industry volume will decline to 35% in 2035, indicating that the aforementioned volume increase will be led by other categories.
The research firm estimates that by 2035, financial derivatives, including event contracts linked to commodities, cryptocurrencies and stocks, will account for 49% of turnover on yes/no exchanges, topping sports to become the largest volume driver. The research firm sees event contracts tied to key performance indicators (KPIs) leading the charge.
