Nicolai Tangen isn’t your typical financial titan. On February 20, 2025, he sat down with David Rubenstein on “The David Rubenstein Show: Peer-to-Peer Conversations,” filmed a month earlier at the Bloomberg House in Davos. As CEO of Norges Bank Investment Management, Tangen runs the world’s largest sovereign wealth fund—$1.8 trillion strong, dwarfing all others. The episode, already at 7,983 views on YouTube, pulls back the curtain on a guy who traded hedge fund glory for a shot at serving Norway. Here’s what he revealed.
The fund, nicknamed the “Oil Fund,” owes its existence to a frigid night in 1969. Phillips Petroleum hit the jackpot on the Norwegian Shelf, striking the biggest offshore oil find ever at the time. Tangen recounted the moment: a 2 a.m. wake-up call to the Ocean Viking platform chief, followed by a Christmas Eve announcement that changed Norway forever. Started in 1996 with 2 billion Norwegian kroner, it’s now a 20-trillion-kroner behemoth, funding 20-25% of the country’s budget thanks to a strict 3% spending cap. Tangen’s job? Steer this giant, owning chunks of over 9,000 companies worldwide, through calm and chaos alike.
His approach is steady, not sexy. “You want to be widely diversified,” he told Rubenstein. Tactical bets are a nightmare with a fund this size, so he preaches spreading the risk—across assets, across borders. He’s a contrarian at heart, eyeing beaten-down Chinese stocks while others chase U.S. tech. AI’s been a goldmine, with American tech giants padding the fund’s returns and his team boasting a 15% efficiency bump from new tools. But he’s not blind to today’s risks. With Trump in office, Tangen sees U.S. deregulation juicing short-term gains, offset by tariff pain for Europe and inflation threats from tight labor and big debt.
Pressure’s a constant companion. The fund’s value ticks live on its website—13 updates a second—and Norway’s 5 million citizens watch closely. “There’s always something going wrong somewhere,” Tangen said, shrugging off the endless gripes about too much of this stock or too little of that. He’s applied for another five-year term, banking on his team’s track record and a push for transparency that’s made Norges the most open fund globally. ESG? Still a priority in Norway, despite America’s cooling on it. His worries keep him up at night: inflation spikes or a wild-card disaster—think Covid or a nuclear mess.
Tangen’s path to this gig is a hell of a tale. Born in Kristiansand, he studied Russian in Norway’s intelligence service before landing at Wharton, where humility took a backseat to world-conquering bravado. He built AKO Capital into a $20 billion hedge fund powerhouse, then walked away, handing his stake to a charitable foundation and joining the Giving Pledge with a billion-plus net worth. “Happiness is about learning,” he said, rejecting the chase for more cash. “The person with the most money when they die has lost.” Now, he skis, picks wild mushrooms for chanterelle spaghetti, and dreams of another degree—maybe not art history, since he bombed that once.
This isn’t just a finance story—it’s a human one. Tangen’s a rarity: a guy who’s crushed it in the cutthroat private sector, then pivoted to public service without losing his soul. The full interview’s on YouTube (catch it here), and it’s worth every minute. From oil rigs to AI, from Oslo to Davos, he’s proof you can manage a fortune and still keep your feet on the ground.
