What happened Shares of gambling giant Caesars Entertainment (NASDAQ: CZR) jumped as much as 12.3% in trading Monday after announcing a big new partnership. The stock bounced mid-day and is still up 9% in trading at 3:05 p.m. EDT. So what Disney (NYSE: DIS) owned ESPN announced that it has entered into separate multi-year agreements with Caesars and DraftKings (NASDAQ: DKNG) to integrate with their digital platforms. Caesars' partner William Hill will have its data featured on ESPN's platforms and integration to its sportsbooks with Caesars' at both physical locations and mobile-betting apps.

And the upside is that when people are watching sports and highlights, they're likely to see the Caesars name, which is great advertising for the platforms. Given how hot sports betting and mobile sports betting, in particular, are right now, it's no surprise that this announcement caused Caesars' stock to pop. Now what This agreement isn't going to fundamentally change Caesars' business immediately, but it could be notable long term. Companies are jockeying for position in the mobile sports-betting industry that could be worth billions of dollars as betting opens up across the country. For a highly leveraged company like Caesars, that's a welcome growth opportunity in a low capital-investment business. As much as I like the agreement, today's pop probably won't last because it'll be years before we see fruit from mobile betting for Caesars. But investors think it's a big deal today, and that's why shares are moving higher. 10 stocks we like better than Caesars EntertainmentWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
