Phantom's March CFTC Letter Just Became a US Prediction Market in Your Wallet

Phantom’s March regulatory letter now has a US trading interface. On October 23, the wallet began a staged rollout of Kalshi prediction markets, turning conditional relief from broker registration into a way to trade inside the app. The interface brings the market closer; the money backing a position still leaves the wallet’s self-custody perimeter.

In Phantom’s launch announcement, General Counsel Kevin Jacobs says access will expand over the coming weeks through its first US integration with Kalshi. Phantom explicitly says it is not CFTC-registered. KalshiEX LLC offers the markets.

What the March letter actually permits

Staff Letter 26-09, issued March 17 under Regulation 140.99, addresses a narrow registration problem. The Market Participants Division will not recommend enforcement against Phantom for failing to register as an introducing broker under CEA section 4d(g), or relevant personnel as associated persons under section 4k, solely for the described software activities.

Its boundary is operational. Phantom cannot hold or control user assets, generate express trading signals, or choose routing or execution at its discretion. Funds securing derivatives positions belong within a custodial structure involving the designated contract market’s clearing organization and/or a futures commission merchant.

Analysis: This is a non-custodial front end over a custodial market. A wallet’s self-custody description does not establish that a user personally holds the money securing a prediction-market position. The screen remains familiar while the custody arrangement changes. That distinction should shape how users understand both account access and settlement.

A US account sits behind the wallet screen

According to Unchained’s launch reporting, US onboarding includes Kalshi identity checks that can require a Social Security number and US government identification. Phantom creates a Kalshi account or connects an existing one. The Kalshi-powered prediction markets Phantom introduced in December were marketed around not needing a separate account; the US version requires one.

Account linking does not merge balances. Money available through Kalshi’s app or website does not appear in Phantom, and the reverse also applies. A user therefore needs to distinguish an existing account relationship from funds available through this particular interface.

Users pay with Phantom Cash, whose CASH token is dollar-pegged, or Solana tokens. Funds move to Kalshi for each purchase; proceeds or winnings return to Cash through Stripe. Phantom’s trading guide describes the purchase and cash-out workflow.

Analysis: The convenience is distribution and payment orchestration. It does not remove identity checks, consolidate every Kalshi balance, or make collateral self-custodied. Those operational distinctions matter before the first order, particularly for someone arriving with funds already on Kalshi.

Two cents needs an honest denominator

The reported charges are $0.01 per contract for Phantom, plus $0.01 for Kalshi, and a variable network fee. For a contract bought at $0.50, the two fixed cents equal 4% of the purchase price, before network costs. The initial outlay is $0.52 before the network fee.

Analysis: Calling that two-cent sum a complete round-trip fee would confuse two fee recipients with two trading legs. It establishes the combined charge on the stated purchase; an early sale requires checking its own quoted fees. If the same two-cent charge applied on exit, purchase-and-sale friction would be four cents, or 8% of the original fifty-cent price, before network costs. That is a conditional calculation, not an asserted exit tariff.

For a contract settling at $1 or zero, a successful fifty-cent purchase leaves $0.48 after the stated entry fees, before other applicable costs. An unsuccessful one loses the $0.52 outlay. Phantom also warns that insufficient buyers can prevent a sale despite a displayed profit. A valuation on screen is not guaranteed executable cash.

Ten conditions follow the software provider

The March letter’s ten conditions can be grouped by their operational purpose:

• Eligibility and notices: The provider, principals and solicitors must avoid statutory disqualification, report relevant changes, notify staff of insolvency or bankruptcy, and file agreement to the conditions and jurisdiction.
• Disclosure and access: Explain venue relationships, fees and conflicts; provide the Regulation 1.55(b) risk disclosure and retain acknowledgements; onboard users directly with a DCM or registered FCM/IB, with independent venue access.
• Marketing and records: Maintain written communications policies as if registered as an IB, avoid promotions requiring NFA Rule 2-29 pre-approval, and retain Regulation 1.31 records.
• Shared responsibility: File a written undertaking with each venue accepting joint and several liability and CFTC jurisdiction.

Analysis: Identity-linked onboarding, disclosures, records and marketing controls reach into the software layer. Wallet teams accustomed to treating these as exchange responsibilities must now design around their own conditions for relief. Avoiding IB registration does not mean shipping without compliance infrastructure. The independent-access condition also matters for product design: the wallet cannot be the only route to the venue. Retained acknowledgements make disclosure a record-keeping task, while the marketing conditions connect promotional decisions to continued eligibility for relief.

The September 17 industry extension, Letter 26-25, makes the template available to passive software providers beyond crypto. Phantom relies on 26-09; other qualifying providers rely on 26-25, since reliance belongs to each letter’s beneficiaries.

Analysis: The distribution opportunity extends beyond prediction markets to regulated derivatives, including perpetual contracts where the conditions fit. That is not blanket product authorization. The practical bottleneck shifts from obtaining an intermediary registration toward finding a venue willing to sign the joint-and-several-liability undertaking and supporting the required controls.

The US menu still follows the state map

The Block reports that launch restrictions differ materially:

• Michigan: Sports markets are blocked.
• Nevada: Sports, elections, politics and entertainment are blocked.
• Washington: Those categories plus culture, science and tech, mentions and geopolitics are blocked.

Michigan’s attorney general announced a preliminary injunction on September 2 requiring Kalshi geofencing of sports contracts, with violations carrying a $500,000 daily fine. The case was remanded to Ingham County Circuit Court after a June restraining order.

The Federal Register proposal recounts conflicting circuit decisions: the Third Circuit treated DCM-traded sports event contracts as swaps in April; the Ninth Circuit found them likely outside that definition on August 28; the Sixth Circuit also rejected swap status on September 25. A Ninth Circuit rehearing petition was filed September 9.

Analysis: Federal registration relief for the interface does not settle the venue’s state exposure. A wallet inherits the practical consequences through its available-market menu.

November 18 is a comment deadline, not legal certainty

The CFTC’s October 9 swap-definition proposal would expressly include event contracts covering sports, politics, culture and weather. Published October 19, it accepts comments until November 18. It remains a proposal. The separate casino-product interim final rule excludes specified gambling products, takes effect on Federal Register publication and has a 30-day comment window.

The software relief has a different clock: it lasts until relevant Commission rulemaking or guidance on software-provider IB registration becomes effective. Staff can modify, suspend or terminate it; it does not bind the Commission.

Analysis: Watch rollout access, state menus and the rulemaking separately. Phantom has made conditional derivatives distribution usable inside a wallet. Neither the interface nor the March letter makes that arrangement permanent.
