I first heard about Kyla Simpson’s story close to a year ago: A surrogate who gave birth to triplets for a father in China, then was left to raise the children after he never retrieved them from the US. The full story is stranger, and sadder, than I could have imagined.

NEW: A college student filmed the exciting moment he won $100,000 – except the bet wasn’t real. A flood of videos showing fake trades and fake wins, is fueling Polymarket’s hype machine, our @wsj.com investigation found. It's part of a secret campaign for Americans’ attention on social media.

1/ After seeing a lot of Polymarket videos on social media, my @WSJ colleagues and I wanted to understand Polymarket’s marketing. After watching a bunch of videos, we noticed that the website featured in them was almost, but not quite, identical to Polymarket’s actual platform.

"On Polymarket, the Journal found, 67% of profits go to just 0.1% of accounts. That means less than 2,000 accounts netted a total of nearly half a billion dollars."

As Propublica’s editors note, “the policy of shielding officers' identities, particularly after a public shooting, is a stark departure from standard law enforcement protocols. “Such secrecy, in our view, deprives the public of the most fundamental tool for accountability.”

NOTE FROM THE EDITORS
ProPublica is publishing the names of the two federal immigration agents involved in the fatal shooting of Minnesota protester Alex Pretti. We believe there are few investigations that deserve more sunlight and public scrutiny than this one, in which two masked agents fired 10 shots at Pretti as he lay on the ground after being pepper-sprayed.
The Department of Justice said it is investigating the incident, but the names of the two agents have been withheld from Congress and from state and local law enforcement.
The policy of shielding officers' identities, particularly after a public shooting, is a stark departure from standard law enforcement protocols, according to lawmakers, state attorneys general and former federal officials. Such secrecy, in our view, deprives the public of the most fundamental tool for accountability.
