About Grease
Yahoo Finance has soured on prediction market Polymarket, closing a deal between the financial news platform and the event contract operator in less than a year after it began.
The two companies began collaborating in November 2025. As part of the deal, Polymarket provided data for a dedicated prediction market section on Yahoo Finance. The feature provided market-based probabilities of economic, political, and financial developments alongside Yahoo Finance content.
The Yahoo Finance prediction market section was taken out in April. The companies have now confirmed that the larger deal is also off, as reported by Bloomberg.
How to play Grease
In 2025, Brazil collected almost BRL10 billion ($1.97 billion) in tax revenue from the licensed sector. In the first seven months of this year alone, BRL8.7 billion generated by the activity was delivered to public coffers. The Federal Revenue Service itself estimates that the sector should reach BRL16 billion in revenue during 2026.
Besides revenue collection, another concern is legal and economic. Companies have paid over BRL2.5 billion for licences since the sector’s regulation. Certainly, the end of the activity would lead to litigation to recover the amounts paid and compensation for investments made. Furthermore, the revenue from betting is already included in the Annual Budget Law and the Budget Guidelines Law, which define the priorities for federal government spending.
What worries the sector is not just the threat of drastic measures against legalised betting. So far, the government has consistently fallen short in its attempts to curb the illegal market, which still represents almost half of the segment.
What is Grease?
But I couldn’t have accomplished half of what I did without all of my colleagues, past and present. Our talented team of writers, editors, web site development guys, production team, on screen reporters, Human Resources, Accountants, everyone. It took the whole team to make sure we put up the latest news and opinions every day, and everyone deserves their fair share of the credit.
To all of those I met at the handful of conferences I attended before Covid-19 sent everything to digital, and all of those I met over email or Zoom since, it was a pleasure to meet you. I hope we get the chance to meet again when all of this is over, and you can reach me at any of my contact details listed at the bottom if you want to catch up in the meantime.
I’m still not 100% sure what I’ll be doing next, but I suspect it will still be in the gambling industry. This has been my life for more than a decade, and it’s an industry I continue to love and appreciate. No matter if I continue to write about it or throw myself back into an operations setting, it will always be apart of who I am. If you still want to be in touch, you can connect with me on LinkedIn, or you can follow me on Twitter if you to know whatever tangent I’ve gone off on next.
