Pivot's analysis combines polls, predictive analysis, wagering markets and social sentiment to create odds on the outcome of world events. The co-founders of Pivit also co-founded Intrade, a similar company that was a web-based trading exchange for political futures.
CNN has a partnership with Pivit to predict outcomes of the 2016 presidential election.
The numbers are a growth from last time early June, when Pivit predicted that Trump needed to "slow his roll" after his incendiary remarks about Mexican immigrants. So far, his poll numbers have only been growing.
Pivit also predicted the 10 Republicans who would participate in the first prime-time Republican debate.
Fox News said Tuesday that the GOP presidential candidates for the debate would be Trump, Jeb Bush, Scott Walker, Mike Huckabee, Ben Carson, Ted Cruz, Marco Rubio, Rand Paul, Chris Christie and John Kasich.
The 10 candidates were taken from five polls, Fox News said, including polls conducted by Bloomberg, CBS News, Fox News, Monmouth University and Quinnipiac University.
