Kalshi Grows to $4 Billion Revenue With No VPs and No 'Heads Of'

Kalshi was on track for $4 billion in annualized revenue as of June, up from $775 million in December — and its co-founder credits a structure with no vice presidents at all.

Luana Lopes Lara, 30, co-founder and COO of the prediction market, told Fortune's Most Powerful Women summit in Santa Barbara, California, that Kalshi has scaled headcount without the bureaucracy that stalls most fast-growing startups. Her method: everyone reports to her, or sits one step away from her. In plain words, Kalshi grew revenue more than fivefold in six months while refusing to build a management layer.

"We are able to very quickly make decisions, and adjust very, very quickly. We're also a very flat organization. We don't have 'heads of' or VPs, or all of that structure. Everyone just reports to me, or one step away from me, and I think that also makes us able to move so much faster," said Lara.

The revenue figure comes from research firm Sacra, which estimated the annualized run rate in June. The December baseline of $775 million implies Kalshi multiplied its yearly revenue pace roughly five times in half a year. Much of that growth came from an explosion of sports betting, though the company has also launched new products, including futures markets for compute. One analyst has suggested Kalshi could be worth as much as $42 billion if everything goes right — a conditional valuation, not a confirmed one. The takeaway: the growth is real, but the biggest numbers attached to it remain projections.

Who is Luana Lopes Lara?

Earlier this year, Lara became the world's youngest self-made female billionaire at 30. Asked how that felt, she said she "is so very grateful, but it is very weird" — but that her routine hasn't changed.

"Very little changed in my life. I'm still in the office over 12 hours every day, and just pretty much try to do the same thing that I always did," she said.

A twelve-hour office day is her stated norm, billionaire status notwithstanding. That is the whole answer on what wealth changed: almost nothing, by her own account.

What threatens the growth?

Litigation. Dozens of state governments claim Kalshi is running an illegal sports gambling operation, and the lawsuits have already produced conflicting rulings from different appeals courts. The Supreme Court is widely expected to rule on the matter next year.

Kalshi argues its sports wagers differ from traditional casino or sportsbook bets because users bet against each other rather than against "the house." Some courts have rejected that distinction. Lara said she is optimistic Kalshi will prevail and that, regardless of the final legal outcome, the company will be able to navigate any future regulatory framework. That confidence, notably, comes before the Supreme Court has agreed to hear the case, let alone rule on it.

What about the odds themselves?

Lara said one of Kalshi's primary challenges is educating people about probabilities. She pointed to the upcoming U.S. midterm elections as an example of how the public misreads prediction market odds.

"I think it's 92% that the Democrats will take the House, but if the 8% happens, I think a lot of the narratives from the media will be that the [prediction] markets are wrong. But actually, something that has an 8% chance means that eight in 100 times it will happen," she noted.

Her framing is statistically correct: an 8% event should occur in roughly eight of every 100 runs. Whether that nuance survives a contested election night is a different question, and she did not address how Kalshi plans to counter such narratives.

What did she say about the Novig ad?

Lara also addressed the controversy over a viral ad campaign by Novig, a new sports-focused prediction market firm, that featured a nearly naked Sydney Sweeney.

"It's not an ad that we would ever put out, or that I, as a woman, would feel comfortable putting out or seeing. I don't think it's the brand that we want to build," she said.

She drew a line between Kalshi's brand and a rival's shock marketing, without naming Novig directly in the quote. The remark signals positioning as the sober incumbent in a market that one analyst believes could reach $42 billion in value — if the courts, and the odds, cooperate.
