The US rapper has previously been condemned over his antisemitic remarks.
The 48-year-old musician - who has not performed in the UK since he headlined Glastonbury in 2015 - is set to top the bill for all three nights of the festival in London's Finsbury Park in July.
On Sunday, a Pepsi spokesperson said: "Pepsi has decided to withdraw its sponsorship of Wireless Festival."
Sky News has approached festival organisers for a response.
In the time since he last performed on UK soil, West has drawn criticism for antisemitic X posts, a Super Bowl advert directing people to a swastika T-shirt and a song referencing Hitler.
Sir Keir said it was "deeply concerning" that West has been booked "despite his previous antisemitic remarks and celebration of Nazism".
"Antisemitism in any form is abhorrent and must be confronted clearly and firmly wherever it appears. Everyone has a responsibility to ensure Britain is a place where Jewish people feel safe and secure," the prime minister said.
West, also known as Ye, has been barred from X over antisemitism on multiple occasions.
In January, West took out a full-page advert in the Wall Street Journal to apologise, titled: "To Those I've Hurt."
"I am not a Nazi or an antisemite," it said. "I love Jewish people."
West attributed his previous outbursts to his bipolar-1 disorder, writing: "In early 2025, I fell into a four-month-long manic episode of psychotic, paranoid and impulsive behaviour that destroyed my life.
"I lost touch with reality. Things got worse the longer I ignored the problem. I said and did things I deeply regret."
The rapper also apologised to the black community, saying he had let it down.
West previously lost his deal with Adidas following a post on his social media in 2022, in which he shared an image of a swastika inside a Star of David.
Adidas, which had worked with the rapper on his Yeezy trainers, subsequently donated more than $150m (£117m) to anti-hate groups.

Shortly afterwards, he drew criticism over a TV advert that directed people to a website selling a swastika t-shirt and released a song titled Heil Hitler.
Sir Ed Davey, the leader of the Liberal Democrats, last week called for the government to ban West from entering the UK.
He said Home Secretary Shabana Mahmood should "ban him from coming to this country - we've got to take antisemitism more seriously".
Sky News understands the Home Office is yet to receive an application for West to enter the UK.
The teenager, identified as Noah Campbell, died after a car was involved in a crash with him and two other teenage boys on Friday night in Flitwick.
Two of the boys were riding a bike, and another was on a scooter.
Noah's family said his death "has left a hole in our lives that will remain forever".
In the statement issued by Bedfordshire Police on Sunday, the family said: "Noah was a fun, bright, handsome, athletic and incredibly well-liked boy.
"Above all else, he cherished spending time with his friends and family; they were the heart of his world."
They added: "Noah was a talented and versatile sportsman. While football was his favourite sport - playing for many local teams - he was a gifted all-rounder who excelled in rugby, cricket and athletics. Outside of organised sports, Noah stayed active and adventurous; he loved challenging himself at the gym and spending time at the bike park.
"Some of his happiest memories were made enjoying attending Liverpool FC and Luton Town FC matches alongside his dad.
"We would like to thank everyone for their kind words and support during this incredibly difficult time.
One of the other boys injured in the crash remains in hospital in a serious condition, while the other was treated for serious injuries and has been discharged, police said.
They added a man and a woman have been charged in connection with the crash.
Jamie Fountain, 24, was charged with causing death by careless driving, and an additional charge of causing death by careless driving while over the legal limit for alcohol and drugs.
He was also charged with two counts of causing serious injury by careless driving in relation to two other boys who were injured in the incident, and further charged with failing to stop at the scene of an accident, failing to report an accident and conspiracy to pervert the course of justice.
Ellie Ireland, 23, of Ampthill, has been charged with conspiracy to pervert the course of justice.

They have both been remanded in custody to appear before Luton Magistrates' Court on Monday.
Detective Sergeant Shona Searle, of the Bedfordshire, Cambridgeshire and Hertfordshire serious collision investigation unit, said: "This incident has sent shockwaves through the small community of Flitwick and the surrounding area, and we maintain a community policing presence around the scene for reassurance.
"While we understand the strong feeling associated with the loss of a young life, and the serious injury of others, we would ask that people do not speculate on the circumstances of the situation.
"The families of the victims, who we are supporting through family liaison officers, have requested that their privacy is respected at this difficult time."
The 100-foot tree fell on four people participating in the event on Sunday morning in woods near the town of Satrupholm.
The baby girl died in hospital, while her 21-year-old mother died at the scene as she was being treated by first responders, as did another 16-year-old girl.
An 18-year-old woman suffered serious injuries and was brought to the hospital by helicopter.
The incident took place as around 50 people from a nearby residential facility for new mothers, pregnant women and children hunted for eggs in the area, which had been under a high winds warning from the German weather service.
Grief counsellors were sent to the scene, where pictures published by the Bild news site showed several Easter eggs scattered on the ground and two of the victims covered in white sheets.
The facility that held the event is part of the state-funded child welfare system and supports pregnant women and new mothers who need help, according to its website.
Prince William and Kate joined the King and Queen and other senior royals at the Easter Matins service at St George's Chapel, Windsor Castle, on Sunday.
William waved to the large crowd outside the castle as he and his wife arrived with Prince George, Princess Charlotte and Prince Louis.
Charlotte was in a tan coat and Kate wore an off-white ensemble of skirt, smart jacket and leafy hat, while William and the boys wore dark blue suits and ties.
Queen Camilla was in a red wool dress and coat by Fiona Clare, a hat by Phillip Treacy and a broach which belonged to the late Queen Elizabeth II.
It's the first time since 2023 that the Waleses have been at the service.
Last year, they opted to spend the Easter weekend with their children in Norfolk, while 2024's service came just over a week after Kate released an emotional video message revealing she had started a course of preventative chemotherapy.
Charles and Camilla arrived by car in front of the castle to a shout of "God save the King" from the crowd on Sunday morning.
Andrew Mountbatten-Windsor's daughters Princess Beatrice and Princess Eugenie were not there, after the King gave them permission to make other plans.

Last year, Charles and Camilla were joined by the former Duke of York and his ex-wife Sarah Ferguson at the 15th century chapel on Easter Sunday.
Since then, Andrew has been stripped by the King of his right to be a prince and his dukedom over his association with paedophile financier Jeffrey Epstein.
Andrew was arrested in February on suspicion of misconduct in public office. He denies any wrongdoing.
Beatrice and Eugenie, who are the King's nieces and have kept their titles as princesses, joined the Royal Family for Christmas at Sandringham in December.
It is understood they will be at family celebrations in the future.
The Princess Royal was accompanied at the Windsor service by her husband, Vice Admiral Sir Tim Laurence.
The Duke of Edinburgh was also in attendance. He was pictured without his wife, the Duchess of Edinburgh.
Aleksandar Vucic said two backpacks with "large packages of explosives" had been left a few hundred metres from the Balkan Stream pipeline.
It's an extension of the Turk Stream pipeline that carries gas from Russia under the Black Sea to Turkey.
Mr Vucic said millions could have been cut off if the explosives had detonated.
"I just had a talk with [Hungarian prime minister] Viktor Orban, and informed him that if the gas pipeline had been cut there, Hungary would not have had gas and we in northern Serbia would not have had gas," he told reporters.
Mr Vucic warned anyone trying to destroy Serbia's infrastructure would face a "merciless" response and "harsh and severe punishment".
On Instagram, he said the explosives potentially had "devastating power".
Mr Orban, who arranged an emergency defence council meeting for Sunday afternoon, said on X "the equipment needed to detonate it" had also been discovered.
The incident comes seven days before Hungarian voters decide whether to extend his 16 years in power.
His party is currently behind in the polls, although many people say they are still undecided on who to back.

Mr Orban, who is seen as one of Russian President Vladimir Putin's closest allies in Europe, increased security around the country's energy infrastructure in February and has framed the election as a choice between war or peace.
The Hungarian leader has often been a thorn in the side of other EU nations and last month blocked a €90bn loan to Ukraine.
