Democratic Presidential Nominee 2028

Platform comparison

Market context

The next Democratic presidential nominee will be chosen through the 2028 primaries and convention, with no formal party decision yet on the table. At a 19% crowd-implied probability, the market is still pricing a broad, unsettled field rather than a single lock-in, which matters because nomination trading tends to re-rate sharply when money can move in quickly through low-friction deposit routes and be pulled out just as fast through SEPA, card rails, or USDC.

Recent coverage still points to an open contest, with Gavin Newsom, Kamala Harris, Pete Buttigieg and Alexandria Ocasio-Cortez all appearing in early rankings and polling, while sources disagree on who leads at this stage[2][3][4][7]. That split is consistent with a market that can stay range-bound until a clearer campaign signal arrives, because early support is often driven by name recognition and media visibility rather than formal candidacy or delegate organisation[6][13]. Comparable 2028 previews have shown the front-runner changing as new polls and betting flows come in, which is why book depth can widen quickly once larger wallets are active[1][8].

For traders, the main catalysts are formal announcements, fundraising reports, debate and primary scheduling, and any sign that a major Democrat is actually assembling a national operation. Newsom’s profile has been buoyed by repeated coverage of his national positioning and clashes with the Trump administration, while other contenders are being tracked mainly through polling rather than declared campaigns[1][16]. In payment terms, markets like this tend to deepen when deposits are cheap and instant, especially where Klarna-style on-ramp convenience, SEPA transfers, and USDC withdrawals reduce friction for larger entries and exits.

FAQ

What does SOFORT cost as a deposit method?

Polymarket Klarna UK charges no fees for SOFORT. The only cost is the internal FX spread (typically <1%) on EUR→USDC conversion. SOFORT itself has no end-user fees — the platform absorbs acquirer costs.

How fast is SEPA deposit?

SEPA Instant: under 10 seconds. SEPA Standard: 1-2 business days. Both accepted fee-free; the internal USDC conversion runs automatically once EUR lands in the platform account.

Can I deposit with a credit card?

Yes, Visa and Mastercard. Credit card deposits carry a ~2.5% acquirer surcharge (standard for card payments). Apple Pay and Google Pay run on the same card rails — same surcharge.

What's the minimum deposit?

10 EUR / 10 USD equivalent. No upper limit, but deposits over $1,500 lifetime volume trigger a quick KYC flow (typically 5-10 minutes).

How do withdrawals work?

Identical methods in reverse. SEPA withdrawal: T+1 (standard) or under 10 seconds (SEPA Instant). Klarna withdrawals process via bank-account refund. USDC withdrawal to external wallet: Polygon gas cost (typically $0.01).
