Billing questions
Before you commit
Can I try Pro before paying?
A free account already covers keyword search, market detail, the full trade tape, and the discover feed. That is enough to judge whether the dataset answers your questions before you spend anything.
When does billing go live?
Square billing is being wired in now. Until it ships, Pro upgrade is disabled rather than collecting payment for something you cannot yet activate.
Is the Automated tier available today?
Not yet. The research platform is live; the execution desk built from our KalshiLayer work is in progress. Create an account to be first in line when it opens.
What happens to my saved work if I downgrade?
Saved searches, reports, and watchlists stay on your account. They become read-only on the free tier rather than being deleted.
Start on free. Move up when the data does the work.
No card required to open an account. The entire Kalshi index is searchable the moment you sign in.
