Joe Hart and Samir Nasri are set to finalise loan moves away from the Etihad Stadium on Wednesday and the Ivory Coast striker is also close to the exit door
Bony arrived at Stoke's training ground on Wednesday in a bid to complete a move before the transfer deadline, although the two clubs are yet to agree on the finer points of the deal.
The Ivory Coast international is yet to feature in a matchday squad this season and City have been actively looking to find him a new home in recent weeks.
West Ham, despite bringing in Simone Zaza over the weekend, had retained an interest right up until Tuesday but have now dropped out of the running.
Stoke are in the market for a new striker and are set for a busy deadline day, with Porto defender Bruno Martins Indi joining Bony at the Potters' training ground.
Bony tweeted on Wednesday morning: "It’s a new day and I look forward to a new exciting challenge."

Both Nasri and Hart are on the verge of clinching loan moves to Sevilla and Torino, respectively, though Mangala's future is less certain.
Porto had been interested in taking the France defender back to the Dragao and a number of Italian clubs were linked with a move, but it appears Valencia are now favourites.
Mangala rejected a move to Mestalla this time last year as City attempted to swap him for Nicolas Otamendi.
