Kalshi complaints: how to contact support, withdraw funds and escalate

This page was checked on 2026-10-20. No published complaint reports are currently linked to this profile. The details on this page come from Kalshi's own pages and the sources named.

• Support. Kalshi's Help Center says the best and fastest route is the support messenger while logged in (in the app: menu, Get help, Chat with support). If chat is unavailable it gives an email fallback, asks that you write from the email on your account, and states that 'Kalshi does not offer phone call or text support at this time.' The article also says the company's support uses AI that is built to resolve requests on its own, with a human reviewing when needed.
• Deposits and withdrawals. The Transfers FAQ (dated August 24, 2026) lists debit card, bank transfer (ACH), PayPal, Venmo, Cash App (deposits only) and crypto, plus wire transfers, and says that Kalshi places temporary security holds on deposited funds before they are available for withdrawal, with hold periods depending on the method. It also says deposits cannot be canceled or refunded once submitted, but that after a deposit clears any hold you can withdraw the funds back to the original payment method.
• BBB. BBB accepts complaints through its profile for Kalshi; its figures are in the complaint-record section.
• State regulators. Several state attorneys general have taken action over Kalshi's sports contracts (see the regulator section). For a gambling-law or consumer-protection concern, the attorney general of your state takes complaints.

State actions about Kalshi's sports event contracts

Massachusetts. In a statement dated 1/20/2026 on mass.gov, the Massachusetts Attorney General said she had secured a preliminary injunction in her lawsuit against KalshiEX, LLC, which the statement calls a 'self-described online prediction market'. The statement says the court's order 'will allow a preliminary injunction to take effect, prohibiting Kalshi from accepting online sports wagers and related events contracts from Massachusetts customers until the company follows the state laws that govern sports gaming, including licensure by the Massachusetts Gaming Commission', and that the order also denied Kalshi's motion to dismiss the lawsuit filed in September 2025. BBB's summary of the same case (read 2026-10-20) says the suit was filed in Suffolk Superior Court on September 12, 2025 and alleges, among other things, that Kalshi allowed users aged 18 to 21 to trade. These are the Attorney General's allegations; BBB labels the matter a pending government action that has not been resolved. Later developments, including any appeal, are not stated here.

Arizona. In a press release dated March 17, 2026 (azag.gov, read 2026-10-20), the Arizona Attorney General said she filed criminal charges against KalshiEx LLC and Kalshi Trading LLC for operating an unlicensed gambling business and for election wagering. The release describes a 20-count criminal information alleging that Kalshi accepted bets from Arizona residents on sporting contests, player propositions and other events, including four counts of election wagering, and says that on March 12, 2026 Kalshi sued the State of Arizona 'preemptively'. The release does not name a court. These are the State's allegations and have not been proven; the current status of the case was not verified as of 2026-10-20. BBB's profile for Kalshi also displays the Arizona matter as a pending government action.

The Massachusetts Attorney General's statement names the defendant as KalshiEX, LLC, and BBB lists 'KalshiEX LLC' as an alternate name for its Kalshi file at 594 Broadway, New York.
