The Greatest Catch

About The Greatest Catch

James Monk, founder of sports data and streaming provider Catalist Sports, has witnessed that dependence directly. Catalist supplies ITF tennis data to Kalshi and Polymarket and has an exclusive US sports-streaming agreement with Kalshi.

The company must also provide data to the firms making markets on those events.

“If we just sold the data to Kalshi in order to list the markets but no one was coming in and placing liquidity, there’s no point in them listing the markets,” Monk said. “We also need to supply the data to the market makers to inform their models.”

Fullstory points out that while 62% of consumers have dabbled in sports event contracts, 42% traded economic or financial derivatives on a prediction market while a comparable percentage transacted in an election or political event contract. More than a quarter traded at least one entertainment or pop culture derivative.

That widening breadth is vital for the industry at a time when some analysts estimate volume could jump to $10 trillion by 2035 – a projection that is largely rooted in other categories surpassing sports for the top spot.  

Nearly a third of respondents told Fullstory that increased event contract breadth could compel them to consistently choose a prediction market over a sportsbook.

If enacted, the bill would amend the Gambling Authority Act (Cap. 19:03). Its provisions would take effect on a date appointed by the responsible minister through an order published in the Government Gazette.

The age proposal was the bill’s most contentious provision. Opposition MPs argued during the committee stage that Botswana should retain the existing minimum age of 21, but the bill passed with Clause 2 intact. The clause would replace references in the Act to “the age of 21” with “the age of 18”.

Botswana’s parliament published the measure as the Gambling (Amendment) Bill, 2026, Bill No. 15 of 2026.
