And prediction market platform Kalshi has fined two users for breaking its rules.

It's Wednesday, February 25th.

I'm Alex Oselev for The Wall Street Journal.

This is the PM edition of What's News, the top headlines and business stories that move the world today.

This just in, four people were shot and killed and six others were injured this morning on a U.S.-registered speedboat after being intercepted in Cuban waters.

That's according to Cuba's Interior Ministry, which also said that the vessel, which was registered in Florida, opened fire on the island's border patrol when they approached the boat on Cuba's north-central coast.

As of this afternoon, the identities or nationalities of the individuals on the boat weren't disclosed.

The U.S.

State Department didn't immediately return a request for comment, while Cuba's Interior Ministry said that authorities are investigating the incident.

The deadly clash comes as the Trump administration has sought to choke off fuel shipments to Cuba in recent weeks.

In fact, today the Trump administration announced that it is loosening some restrictions on fuel shipments to the country amid a growing humanitarian crisis.

The U.S.

Treasury today said that it would allow the resale of Venezuelan oil to private companies in Cuba, though sales to the government in Havana are still illegal.

It also said that some shipments of American fuel would be allowed for a handful of U.S.

companies.

As we reported earlier this week, the chaos over President Trump's tariffs is sending business leaders scrambling to sort out what may come next.

But some on Wall Street are seeing an opportunity.

Investment firms are buying companies' rights to any refunds they might be due.
