south carolina senate: Andrews Beats 69.5% Polymarket Favorite

south carolina senate produced Polymarket’s loudest early midterm miss: before 23:00 CET on November 3, Darline Graham sat at about 69.5% Yes, Annie Andrews was the underdog near 30.5%, and by morning Andrews had won. Cryptoticker’s postmortem called it the biggest miss among the nine Senate markets that had been called by 05:30 CET — eight of those nine favorites were correct. On Polymarket’s South Carolina winner market, the Democratic win contract later traded near certainty on our gamma snapshot.

What actually happened

Cryptoticker compared last Polymarket prices before 23:00 CET — one hour before the first polls closed in Indiana and Kentucky — with NBC News race calls through 05:30 CET. On that board, South Carolina listed Graham 69.5% as favorite and Andrews as winner, marked “No” for the favorite. The same table shows other called races such as Iowa (Turek 50.5%), Kansas (Hamilton 64.5%), Ohio (Brown 72.5%), Texas (Talarico 76.5%), Florida (Moody 87.5%), New Hampshire (Pappas 95.0%), Georgia (Ossoff 97.2%), and North Carolina (Cooper 98.0%).

Cointelegraph’s live midterm desk, using Associated Press calls, reported Democrats securing a Senate majority after Josh Turek’s Iowa win pushed Democrats and independents who caucus with them to 51 seats. That national story is why south carolina senate still matters beyond one state: it was the rare called race where the crowd’s money was wrong while the chamber still flipped.

Cryptoticker’s context line is specific and we will not embroider it: Darline Graham “was appointed after her brother Lindsey Graham died in July,” and she was priced at 69.5% before polls closed. Andrews’ win is also described there as the first Democratic Senate win in South Carolina since 1998 in a state Trump carried easily in 2024.

What Polymarket thinks

After the call, the south carolina senate Democratic win contract sat near 99.95% Yes on the gamma snapshot we stored for this batch, with high volume on the Dem side historically near the ~$2.2M Cryptoticker/Polymarket notes referenced for the race. That is a settled-market print, not a forecasting edge.

Near-100% after a network call is bookkeeping, not brilliance. The interesting number was 69.5% the night before.

Nationally, Cryptoticker said Democratic sweep odds moved from 73.5% at 23:00 CET to 98.7% at 03:00 CET, with NBC calling the House at 04:08 CET and the Senate at 05:26 CET. About $164 million traded on the three national markets and about $67 million on 14 Senate markets. south carolina senate was the hole in an otherwise sharp favorite night.

Why the miss teaches more than the hit rate

Average pre-close favorites around 79% implied roughly seven wins out of nine; eight arrived. That is a good night and a small sample. The money simply did not see South Carolina coming. Prediction markets are not oracles — they are crowds with positions, and appointed successors in historically red seats can look safer on a screen than they are on a ballot.

For crypto readers, the lesson pairs with house control 2026 odds and senate democrats 2026 odds: chamber markets can be right while a single state market is wrong, and regulatory narratives should not be built on one scar. Cointelegraph flagged that Democratic Senate control reshapes the outlook for the stalled CLARITY Act and committee leadership over crypto — none of which required Graham to win.

How to read a called race without rewriting history

Keep pre-close and post-call prices in separate mental buckets. Quoting 99% after Andrews won as if the market “predicted” her is cheating. Quoting only 69.5% without noting the later call is also incomplete. south carolina senate coverage should show both timestamps.

Also respect name precision. Cryptoticker’s board uses Darline Graham and Annie Andrews; do not silently swap in other candidates. If you cite the Lindsey Graham death context, attribute Cryptoticker — we are not independently confirming obituaries here.

What to do as a reader

If you use Polymarket as a night-of dashboard, pair state boards with national sweep and chamber markets, and refresh after each network call. Read Cryptoticker’s midterms odds postmortem for the favorite table, and Cointelegraph’s live desk for AP-based chamber context.

Treat south carolina senate as a reminder that 70% favorites lose sometimes — especially in special political circumstances. Size small if you trade these books at all. Nothing here is investment advice, and resolved contracts are history, not a tip sheet.
