South Carolina Senate Election Winner

Platform comparison

Market context

The 2026 South Carolina U.S. Senate election will determine who holds the seat for the next six years, with the Republican primary already concluded on 9 June 2026 where incumbent Lindsey Graham secured the nomination [1]. The market currently assigns an 81% probability to a Republican victory and just 20% to a Democrat, reflecting the state’s deep historical tilt toward the GOP in federal contests [3][4]. South Carolina has not elected a Democratic senator since 1976, and even in the 2024 presidential cycle, the state voted 58% for the Republican candidate, making a Democratic Senate win a significant outlier rather than the baseline expectation [4].

Traders should monitor the general election date on 3 November 2026 and any potential runoff scenarios if no candidate exceeds 50% in the initial vote, as South Carolina law mandates a second round in such cases [7]. Graham’s campaign finance filings and early voting data from the FEC will offer early signals on his fundraising strength and voter outreach [6]. A recent Cook Political Report analysis confirms Graham remains the favourite over Democrat Annie Andrews, noting that his runoff performance will be critical to maintaining his lead [7]. The market’s book depth is directly tied to funding flows enabled by Klarna and SEPA on-ramps, which determine how quickly liquidity can enter to reflect new information as these catalysts unfold.

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.

Which payment methods are supported?

Klarna (Pay Now / Pay Later), SOFORT, SEPA bank transfer, credit card (Visa/Mastercard), Apple Pay, Google Pay, and direct USDC deposit on Polygon. Availability depends on your jurisdiction.

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.

Are payment details protected?

Yes. Card and bank details are never stored by Polymarket Klarna UK — they pass directly through PCI-DSS compliant payment service providers (Adyen, Stripe). Polymarket Klarna UK retains only transaction IDs and Klarna reference numbers for reconciliation.
