Phantom brings Kalshi prediction markets to US users as legal fights mount

Kalshi is a prediction-market venue, and Phantom is a wallet that can place crypto users inside new financial products without requiring a separate app or exchange account. In the United States, prediction markets sit in a contested regulatory space because they can be treated as financial markets even when they resemble betting on events. This rollout lands while that line is still being argued over in court and in policy circles.

For Phantom users who qualify in the United States, the practical change is access to event contracts from inside the wallet rather than through a separate platform. That can lower the friction of entering these markets and makes event trading part of a mainstream crypto wallet experience. It also puts more pressure on wallets and market venues to manage eligibility, disclosures and user routing carefully.

The bigger issue is the tension between a product built for broad access and a legal structure that is not settled across federal and state lines. Prediction markets can expand how people express views on elections, sports or other events, but they also pull consumer-facing crypto products closer to regulated financial activity. If this model spreads, the fight will not just be about one market or one wallet; it will be about who gets to define what counts as a prediction market in the US.

The move was larger before the first headline than after. That is an observation, not an explanation: the market also moves on things nobody publishes.
