2025–present: Campaign activity In 2025, Piker began campaigning for political candidates.[72][2] Piker has appeared with political candidates during campaigns that sought support from popular internet personalities to reach voters online.[73] He has also supported candidates online. Piker said he was "very clear" that he was not "some socialist kingmaker", believing the media was not "that powerful".[74][75]

In the 2025 New York City mayoral election, Piker expressed support for Zohran Mamdani, and Mamdani appeared on Piker's stream.[76] During the campaign, Mamdani's political opponents used Piker's past remarks, especially his 2019 comment that "America deserved 9/11", in attacks against Mamdani, including in a televised advertisement aired by a pro-Andrew Cuomo super PAC.[77] Mamdani disavowed Piker's comments during a mayoral debate, calling them "objectionable and reprehensible".[78]

During a March 2026 livestream, Piker helped raise more than $56,000 for congressional candidate Oliver Larkin.[79] Wired called this an example of content creators using their online influence for direct fundraising.[79]

Piker rallied in Philadelphia with state representative Chris Rabb during the 2026 primary for Pennsylvania's 3rd congressional district, which Rabb went on to win in May.[80][81][82] Piker also campaigned for and hosted Adam Hamawy on stream during his run in New Jersey's 12th congressional district. Hamawy won his primary in June. Another congressional candidate Piker endorsed, hosted, and campaigned for, Saikat Chakrabarti, finished third in the nonpartisan primary for California's 11th congressional district, failing to advance to the general election.[74]

In June 2026, Piker was refused entry to the UK alongside Cenk Uygur, which he argued was "due to my criticism of Israel". The UK Home Office said the decision was due to Piker's "potential risk" and because his presence "may not be conducive to the public good".[83][84][85][86] Free speech activists criticized the decision.[87] He had been invited to speak at the Oxford Union and SXSW London. The Oxford Union said Piker would deliver his speech via livestream.[88][89][90] Piker said the decision showed the "fascist" direction the "Western world" was taking.[91]

Ahead of the 2026 Democratic primaries for the House of Representatives in New York, Piker campaigned at a June event in Bushwick, Brooklyn, for Claire Valdez and Darializa Avila Chevalier, who went on to win the Democratic nominations in New York's 7th and 13th districts, respectively.[92] That same month, Piker hosted Melat Kiros on his stream ahead of her primary challenge to Diana DeGette in Colorado's 1st congressional district.[93][94] Kiros defeated DeGette in her primary.[95]

During the 2026 Democratic Party primaries in Michigan, Piker campaigned for Democratic candidate Abdul El-Sayed. Two of El-Sayed's opponents, Mallory McMorrow and Haley Stevens, criticized Piker's involvement based on past remarks, particularly about the Israeli–Palestinian conflict.[96][97] Democratic State Representative Carrie Rheingans chose not to participate in the event with Piker while continuing to support El-Sayed.[98] Piker's involvement in the Michigan primary became a source of division within the Democratic Party.[99][100] El-Sayed won the primary.[101] Piker also campaigned with Donavan McKinney, who defeated incumbent Shri Thanedar in the August primary for Michigan's 13th congressional district.[102] That month, former Missouri congresswoman Cori Bush, who had campaigned with Piker at a May Day rally in St. Louis, lost her bid for the Democratic nomination in Missouri's 1st congressional district to her successor, Wesley Bell.[103][104]
