The Philadelphia ABC affiliate WPVI recently reached out to the WWE as to why Philadelphia did not win the bidding to host Wrestlemania 31 or 32 in 2015 or 2016 respectively.
WWE then issued the following statement to WPVI:
“While Philadelphia expressed a great interest in hosting WrestleMania in 2015 and 2016, the fact is the city did not submit a formal proposal because the facilities necessary to host ancillary events weren’t available. Philadelphia remains a strong market for WWE in all aspects of our business.”
