Kalshi tightens rules on insider trading

The social media companies were accused of intentionally designing their platforms to be addictive, which caused harm to a young user’s mental health. The companies were ordered to pay $6 million in damages — and they’ve told media outlets they disagree with the verdict and are exploring their legal options.

Marketplace’s Stephanie Hughes spoke with Maria Curi, tech policy reporter at Axios, about all these headlines for this week’s “Tech Bytes: Week in Review.”
