What is Double Rainbow?

Polymarket and other prediction markets that ventured into sports trading last year maintain that they’re financial platforms governed by federal law.

The Commodity Futures Trading Commission (CFTC) agrees, continuing to defend its claimed “exclusive jurisdiction” over sports prediction markets in federal and state courts across the nation.

What is Double Rainbow?

In this context, the regulations developed to protect players begin to function as a means of legitimisation, with illegal operators even using the term “authorised” in their communication and the “.bet” extension in their domain, which is intended only for licensed operators.

According to the governance policies of Meta, the owner of Instagram, gambling platforms can use programmatic advertising services and branded content, provided they receive authorisation from the platform. They cannot target content to individuals under 18 or territories where gambling is not regulated.

To obtain Meta’s approval, the company needs to fill out a form and attach documents proving its operating licence. This same form includes a contract, in the form of an “I accept the terms and conditions” button. In it, the advertiser releases Meta from liability for any violations of the content, including legal or administrative proceedings.

About Double Rainbow

“The new hub will display probability data from Polymarket for key economic, government, & market outcomes,” said Polymarket in a post on X last November. “Each probability view will be paired with related news, quotes, & analysis from Yahoo Finance + its partners. By combining trusted data with in-depth analysis, the hub will empower investors to make smarter, more strategic prediction market investments.”

Yahoo—which is 90% owned by private equity giant Apollo Global Management, the firm that acquired operating control of The Venetian in Las Vegas—did not elaborate on why the Polymarket integration ended.

Yahoo Finance is one of the most visited financial news websites in the world, implying it’s a blow to Polymarket that its prediction market hub was pulled, but the operator has other prominent financial media deals.
