(Substack)—State Farm Stadium in Glendale, Arizona, has hosted Super Bowls, rock concerts, and championship games, but next Sunday it will open its doors for something far more profound: a gathering to celebrate the life of Charlie Kirk, the young firebrand who built Turning Point USA from a teenager’s idea into a powerhouse of conservative activism.

The event, simply called “Building a Legacy, Remembering Charlie Kirk,” promises to draw thousands to the 63,000-seat home of the Arizona Cardinals—potentially swelling to 73,000 for what organizers describe as a fitting tribute to a man whose voice reached millions.

Turning Point USA made the announcement on X over the weekend, inviting supporters with a straightforward call: “Join us in celebrating the remarkable life and enduring legacy of Charlie Kirk, an American legend. The morning of Sunday, September 21, at State Farm Stadium, home of the Arizona Cardinals, in Glendale, AZ.”

Doors swing open at 8 a.m., with the program kicking off three hours later. Registration is open now at fightforcharlie.com on a first-come, first-served basis, and early signs point to a crowd that will test the venue’s limits. President Donald Trump has already confirmed he’ll be there, joining what could become one of the largest public memorials for a conservative leader in recent memory.

Kirk’s story starts small but ends with echoes that still reverberate across the globe. At just 18, he launched Turning Point USA in his parents’ garage in Lemont, Illinois—a scrappy outfit aimed at countering what he saw as liberal bias in schools. Over the next decade-plus, it exploded into a network with chapters on hundreds of campuses, mobilizing young people around core principles like limited government, free markets, and unapologetic patriotism.

Kirk didn’t just talk the talk; he turned conservatism into a badge of pride for a generation that grew up online. As one analysis put it, through TPUSA, he “remade Gen Z” by making right-leaning ideas a cultural force on campuses, where they once felt like whispers in the wind.

The memorial website captures this drive in raw terms, painting Kirk as a man who lived on the front lines. “Charlie died doing what he loved: fighting for truth, for faith, for family, and for America,” the tribute reads.

Those words land heavy after Wednesday’s horror in Orem, Utah, where a single bullet cut short his speech at Utah Valley University. Rushed to Timpanogos Regional Hospital, the 31-year-old husband and father was pronounced dead there—a shocking end to a life spent rallying against what he called the erosion of American values. That final act, speaking truth amid threats, mirrors the battles he waged daily, from exposing campus censorship to amplifying voices drowned out by the mainstream.

He was unapologetic and outspoken about his Christian faith. His death wasn’t a detour; it was the ultimate stand, one that now rallies his followers to pick up the torch with even fiercer resolve.

Elaborating on that sacrifice, the site’s message drives home Kirk’s role as a mentor to millions: “He showed a generation that truth must never be silenced, that courage is contagious, and that freedom must be protected at all costs.”

His actions and words did more than inspire. He helped empower others to at as well. TPUSA’s Professor Watchlist empowered students to call out ideological overreach in classrooms, sparking debates that forced universities to confront their own echo chambers.

Kirk’s podcast and X posts—amassing followers who hung on his every take—did the same for broader culture wars, from election integrity to border security. Even in death, his reach grows; social media metrics show his accounts surging with new engagement, as fans and his widow predict his message will only amplify. College Republicans across the country are already vowing to channel this energy, turning grief into action on their own turf.

Faith threaded through all of it, a constant Kirk leaned on publicly and privately. The tribute closes with a biblical nod that feels tailor-made for him: “His legacy will endure for generations. And now he hears the words of Matthew 25:23 from his Lord and Savior: ‘Well done, good and faithful servant.’”

It’s a verse about stewardship, about building something lasting and handing it off stronger than you found it. Kirk did that, allying with Trump early and helping shape a youth movement that powered conservative wins from midterms to the White House. His influence on young voters, once dismissed as fringe, became a game-changer, pulling Gen Z toward ideas rooted in tradition and self-reliance.

As memorials pop up from Berlin to backwater towns in the heartland, this Arizona send-off stands out for its sheer ambition. It’s not just a goodbye; it’s a launchpad for the fight Kirk embodied. With Trump in the stands and thousands filling the seats, expect speeches that blend eulogy with battle cry—reminders that one man’s voice, silenced too soon, can still shake the foundations.

For those who knew him or followed from afar, September 21 offers a chance to stand together, honoring a legacy that’s just getting started.
