What is Kalshi’s email format?
Format | Example (fictional name: Maya Chen) | Share of known addresses | Status |
|---|---|---|---|
{f}{last}@kalshi.com | mchen@kalshi.com | 99% (LeadIQ) | Current, standard |
{first}{last}@kalshi.com | mayachen@kalshi.com | 1% (LeadIQ) | Rare |
LeadIQ puts {f}{last} at 99% of Kalshi addresses (LeadIQ), and Clay lists the same pattern (Clay) (checked Nov 3, 2026). Prospeo is the outlier, putting {first}{last} first (Prospeo); try mchen@ before mayachen@.
A pattern-based address is an educated guess, not a confirmed one. Run it through an email verifier before you send, because a bounce hurts your sender reputation.
Which domains does Kalshi use?
kalshi.com: the website, the app and staff email. Its mail servers are Google Workspace, its SPF record ends in -all and its DMARC policy is set to quarantine, so mail that fakes an @kalshi.com sender should land in spam (DNS checked Nov 3, 2026).
help.kalshi.com and news.kalshi.com: Kalshi’s help center and newsroom.
kalshi-public-docs.s3.amazonaws.com: where Kalshi hosts public documents such as its privacy policy (Kalshi).
Is that email really from Kalshi?
Kalshi’s help center warns: “Be cautious of phishing - only log in at kalshi.com. Kalshi employees will never ask you to send money or crypto to ‘verify’ your account.” (Kalshi) Employees will also never ask for your password or one-time codes.
Fake exchanges use Kalshi’s name. kalshi.com.ro, registered in June 2026, is listed as a fake exchange on phishing blocklists (PhishDestroy). Only kalshi.com is Kalshi’s exchange.
Check the domain after the @: genuine Kalshi email comes from kalshi.com or one of its subdomains.
