Activision will have spent around $500 million (£296m) developing, manufacturing and promoting Destiny by the time the game is released.
The remarkable figure was revealed by Activision CEO Bobby Kotick at the Milken conference in LA, Reuters reports.
"If you're making a $500 million bet you can't take that chance with someone else's IP," Kotick reportedly said. "The stakes for us are getting bigger."
A spokesperson for Activision later confirmed the $500 million figure was accurate, but stressed that it included marketing, packaging, infrastructure support, royalties and other costs.
According to analysts speaking to Reuters, the amount is likely to break the record for the most money spent on a single video game, with estimates that Rockstar spent around $260 million on
Grand Theft Auto V. These analysts suggest that in order to break even, the game would have to sell around 15-16 million units.
"Bungie's very ambitious plan is designed to unfold over a ten-year period" an Activision spokesperson explained. "The depth of creative content, scope and scale is unprecedented and is required to bring Bungie's vision to life."
It also added that some of the $500 million has been spent on a new engine and a "robust backend infrastructure", which it noted "are upfront expenditures that should reduce future product development costs".
