For Marantelli, the exchange format could also cause some customers to lose money faster than they would with a conventional sportsbook. The ability to enter and exit positions creates a perception of flexibility, but that optionality can encourage users to commit more of their bankroll.

A customer might buy a team at 55 or 56 cents expecting the price to rise to 58 or 59 cents, he explains. If it falls to 45 cents instead, the trader may refuse to accept the loss and continue holding the position.

“People will lose money faster on exchanges for lots of reasons,” Marantelli says. “It inherently increases spend, volatility, lots of things. And you’re playing against a sharper audience than you’re playing against at the DraftKings sportsbook.”

In his new role, Konstakis will be responsible not only for OpenBet’s strategy, but also for its day-to-day business, growth initiatives, and tech priorities. At the same time, he will be tasked with “raising the bar” in how OpenBet serves its clients.

OpenBet emphasized that this change comes at a strong moment for the company and follows its incredibly successful delivery for customers through the World Cup. Throughout the tournament, OpenBet processed 175 million bets totaling $3 billion.

CEO Levin, who is set to transition to a chair role, commented on the shift, saying that he was very confident that Konstakis has what it takes to be CEO and drive OpenBet to new heights.

“It was still very much a trading kind of UX,” he said of Kalshi at the beginning of the year. “The actual product offering has come a long way.”

Andrew Gonzalez, founder of prediction market infrastructure startup ParlayX, believes the ability of small teams to provide liquidity is one of the sector’s defining features. “Anyone can be a market maker,” he said. “You have these two- or three-man shops.”
