Josh Kushner Celebrates 40th with Star-Studded Bash at Katz’s Deli

Josh Kushner celebrated a milestone birthday in true New York fashion — with a high-profile party at one of the city’s most iconic delis. The entrepreneur and investor turned 40 in style over the weekend, throwing a festive, celebrity-studded gathering at the legendary Katz’s Delicatessen in Manhattan.

The event drew a notable guest list, blending politics, fashion, and Hollywood flair. Among those who turned up to honor Kushner were his brother Jared Kushner and sister-in-law Ivanka Trump, who made a rare public appearance in the city for the occasion.

Iconic Venue Sets the Vibe

Hosting the celebration at Katz’s Deli was a nod to classic New York roots. The famed eatery, known for its towering pastrami sandwiches and cinematic history (think “When Harry Met Sally”), was transformed into a party spot full of laughter, music, and memories. Guests reportedly enjoyed traditional deli fare served with a side of nostalgia, giving the upscale affair a grounded, hometown twist.

Kushner, co-founder of Thrive Capital and husband to model Karlie Kloss, is no stranger to high society. But this birthday gathering was more than just glitz — it had a warm, intimate energy that felt like a reunion of family and close friends.

A Family Affair

While Karlie Kloss kept a relatively low profile throughout the evening, her presence was quietly felt. The couple, who share a son, tend to keep their family life private, and this celebration was no exception. However, the spotlight did fall on Jared and Ivanka, who mingled comfortably with guests, exchanging smiles and enjoying the relaxed vibe of the event.

Their appearance sparked chatter, given how rarely they’ve been seen at public functions in recent months. Nonetheless, they appeared to be in good spirits, there to support Josh on his special night.

A Stylish and Subtle Crowd

The party attracted a range of stylish figures from the business and entertainment worlds. While the full guest list wasn’t public, attendees were seen arriving in understated but chic looks, blending modern elegance with classic NYC cool. With no official red carpet or formal press access, the gathering leaned into exclusivity, staying true to Kushner’s typically reserved social demeanor.

Inside, the atmosphere was lively but intimate — think soft lighting, curated playlists, and the unmistakable aroma of a deli that’s fed New Yorkers for generations.

A Night to Remember

As Josh Kushner entered his fifth decade, the night served as a reflection of his journey: rooted in legacy, surrounded by family, yet firmly planted in the world of innovation, influence, and understated glamour. The bash at Katz’s wasn’t just a birthday celebration — it was a love letter to the city and the life he’s built within it.

Whether you’re a fan of classic deli sandwiches or NYC’s power circles, one thing’s for sure — this birthday party was as unforgettable as the man at the center of it.
