Television advertising rates for Sunday's cricket final between India and Pakistan are 10 times the normal price, industry sources said, as millions of fans are expected to tune in for a clash that last time ranked among the six most-watched sporting events.

Pakistan, the lowest-ranked team at the Champions Trophy tournament, upset host and favourites England to set up a final with defending champions India, feeding a frenzy for a game that commands a fanatical following in the region and among its diaspora.

A 30-second spot during the final to be broadcast by Rupert Murdoch's Star Sports is expected to cost nearly INR10 million ($155,267), far higher than the INR1 million that advertisers pay on average for most Indian shows, said a person involved in buying ads.

Most of the TV spots for the final, to be played in London, were pre-booked with firms such as Nissan Motor, Intel Corp, Emirates, Chinese mobile maker Oppo and Indian tyre maker MRF signed up as commercial partners for the tournament.

Fewer than 10 percent of the slots are left for the final, a person in the sports broadcasting industry said.Companies still wanting to air their ads will be paying a higher rate than those who pre-booked, said the person, who did not want to be named, citing business confidentiality.

“India v Pakistan Final... !!!!!!!! All TV execs around the world are now cracking a nice bottle open to celebrate,” tweeted former England captain Michael Vaughan.

India captain Virat Kohli is the only cricketer among the world's 100 highest-paid sportsmen, ranking 89th with an annual income of $22 million, according to a list compiled by Forbes.

Before the Champions Trophy, the last time India and Pakistan played a one-day international was during the 2015 World Cup. That game, won by India, was one of the top-six most viewed sporting events, along with the soccer World Cup final and Usain Bolt's 100-metre sprint at the 2012 Olympic Games, the sports broadcasting industry source said.

“That was a league game, this is the final,” the person said. “You can expect this to be even bigger.”

India and Pakistan have already met during the tournament's group stage, with India winning easily. More than 200 million people watched that game, according to Indian media, citing BARC India. For Sunday's final, viewership is expected to be 30-40 per cent higher.

Troubled history

Cricket between the neighbours and rivals has been limited because of their longstanding political problems.

They last played a bilateral series in 2012-13, when Pakistan toured India for two Twenty20 games and three one-day internationals.

It was their first series since the 2008 Mumbai attacks when Pakistani militants went on a killing spree that left 166 people dead in India's financial capital. India has since refused to play Pakistan outside International Cricket Council events.

In disputed Kashmir, the cricket tournament has already caused discord.

Residents of India-held Kashmir, many of whom support the Pakistani team, lit fire-crackers to celebrate Pakistan's victory over Sri Lanka earlier in the tournament.

Later that night, residents in a village in south Kashmir accused Indian army soldiers of beating them and smashing their cars and windows to punish them for celebrating.
