Sydney Sweeney may have been publicly crucified for stripping off to promote sports prediction platform Novig last month, but it looks like the actress is having the last laugh. 

Since getting her gear off for Novig's raunchy ad campaign, the company's valuation has ballooned from $500million to $2billion, according to the Wall Street Journal.

'Novig continues to field investor interest and could raise additional capital soon at an even higher valuation,' reported the outlet. 

Sweeney holds an equity stake in Novig, which she secured before stripping off for Novig's now viral 'Just Sports' ad campaign. 

While her share is unknown, even just 1% is now worth $20million. 

Sweeney was one of the decision makers behind the lucrative campaign, which saw her pose completely naked with nothing but sports equipment to protect her modesty.

'It was a very exciting process to work with her both on the commercial side as well as on the creative side,' Novig CEO Jacob Fortinsky recently said.

'It really was Sydney who was driving a lot of the visuals and the messaging.'

Sweeney echoed Fortinsky's comments, telling Complex, 'I've always believed that the best partnerships are the ones where everyone's getting to collaborate.'

She continued, 'I don't like to just put my face on something. I really want to be able to get into the weeds of it with an amazing team.

'Being able to be a part of watching this company grow and not just be the face of it is really important to me.' 

Despite the racy ad campaign going viral, Sweeney lost more than 200,000 Instagram followers after it launched.

It was slammed by many in the sports world, with several high profile female athletes arguing that it made a mockery of women's sports.  

'When we're trying to provide role models for young people and young women in sport, we really want to show that it's about what your body can do, not so much what it looks like,' British sprinter Amy Hunt told Good Morning Britain.

Australian boxer Skye Nicolson posted at the time, 'Giving the ad campaign exactly what they wanted, but honestly these companies need to do better. Stop sexualising women in sport.' 

In the commercial, Sweeney gets completely naked and uses a variety of sports equipment to cover herself.

'Think you know sports? Prove it. Novig is just sports,' she purrs.

Sitting naked on a basketball hoop, she continues, 'So they wanted a show? Just sports.'

Sweeney, now wearing just shoulder pads and a football placed over her nether regions, adds, 'You can trade this sport. And this sport.'

'No betting on wars or deaths and no politics. Just you, your takes, and sports,' she later continues.

Novig is a prediction market app, similar to Polymarket and Kalshi, but it only allows users to make predictions on sports and nothing else.
