Spartan King

What is Spartan King?

The initial batch of FSPIs launched with NHL performance gauges, triggering a wave of filings from exchange-traded fund (ETF) issuers seeking to launch futures-based funds for each professional hockey team. One issuer even filed plans for leveraged ETFs tied to the NHL indexes.

A similar scenario is playing out on the back of the MLB index introduction. Both LeagueShares and RexShares filed plans for ETFs tied to the FutureSports MLB indexes.

If approved, the funds would hold baskets of the CME-traded derivatives. LeagueShares went a step further by adding a filing for 2x leveraged MLB futures funds.

About Spartan King

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.

The pure-play prediction market-operators, Polymarket and Kalshi, emerged from Week 1 as the clear winners. On one hand, Kalshi’s market share lead narrowed over its competitors, falling to 82% for the week ended 13 September, down from 86% a week earlier.

Still, Kalshi had a nine-fold lead over Polymarket, its next closest rival. Polymarket, meanwhile, led the group with 762,000 app downloads, edging Kalshi, DraftKings and FanDuel in the category. The downloads represented a 13,509% weekly increase and 25% of total category downloads, Polymarket wrote in a statement.

“We’re doing this 100%,” COO Stefan Grenstad says of Cubeia’s AI-driven development process.

Now, the focus is on what the company does with the additional capacity AI has created. Six months ago, Cubeia’s experiment was essentially about replacing human-written code with AI-generated code.

Since then, it has evolved into something broader: a different development pipeline, a different role for developers and quality assurance (QA), a different way of organising teams and, increasingly, a different relationship with customers.
