32% of all bets have been placed on Pellegrini signing the midfielder for the 18/19 season.
The Hammers have been cut from 10/1 a matter of weeks ago, into 5/4 favourite to snap up the England international.
Manuel Pellegrini’s new-look West Ham side have reportedly been given cash to land the 26-year-old, who was left out of Gareth Southgate’s World Cup squad.
Elsewhere, Crystal Palace are also attracting attention for Wilshere’s next club at 6/1, followed by Eddie Howe’s Bournemouth (7/1), Wolves (8/1) and Everton (10/1).
Oddschecker spokesperson George Elek said: “After spending 17 years at the club, Wilshere will finally depart Arsenal for pastures new – with West Ham the most likely destination according to bookmakers.
“Pellegrini’s side are easily the most popular with punters, attracting 32% of all bets on his next destination – far more than any side.”
