The five-time Ballon d'Or winner has headed to the Serie A side for a reported £105 million and dabblebet have several special markets for punters wanting to predict his exploits in Italy.
Lionel Messi is 1/2 (1.50) to outscore Ronaldo during the 2018-19 season in match bet between the pair.
The Argentine has been the leading marksman in La Liga for each of the past two years and it's understandable to see the younger striker priced accordingly. It's 6/4 (2.50) that Ronaldo comes out on top in the season-long race.
Elsewhere, the online bookmaker go 5/6 (1.83) that Ronaldo scores at least 33 league goals next term. That's a number that the Portugal international has surpassed in five of his nine domestic campaigns at the Bernabeu although his last two years have yielded 25 and 26 La Liga goals respectively.
The same 5/6 (1.83) is available for those who believe the value lies with under 32.5 Serie A goals in the 2018-19 season.
While Juve are a more dominant domestic force, their Champions League ambitions might mean Ronaldo's playing time is more closely managed than ever before so opposing such a high line could pay dividends, especially given the likelihood of another tabbe topping triumph.
dabblebet are just 6/10 (1.60) that the Old Lady retain their Serie A crown although that could well get even shorter in the coming days given this announcement.
The more interesting selection is the fact that Juve have been cut from 9/1 (10.0) to 8/1 (9.0) for the Champions League. Having been beaten finalists in two of the previous four editions, Ronaldo's addition should mean Juve continue to be legitimate challengers for the European crown.
Anyone who believes the five-time Champions League winner can lead his new side to glory while topping the scoring charts can take a juicy quote of 28/1 (29.0) with dabblebet.
That price looks a little too big considering Ronaldo has top scored in each of Real Madrid's three European consecutive victories including 15 in last season's tournament. He also holds the record for the most strikes in a single year after a 17-goal haul in 2013-14.
Obviously this is a bigger challenge than leading Los Blancos to glory in Europe's premier club competition but there is no one else who excels at that level quite like Ronaldo does.
His experience and 120 goals on this stage is unparalleled and while Juventus have fallen just short on two occasions, Ronaldo's arrival might be the star power and cutting edge to mean that Juventus can go all the way.
If Juve are to put together a serious European challenge then their new star signing is likely to play a pivotal role. While the 8/1 (9.0) about a Champions League victory might be tempting, a smaller wager on the 28/1 (29.0) is the ideal additional wager considering his prowess on the biggest club stage.
