How Polymarket Resolved Bitcoin's $80,000 Contract

Polymarket's "Will Bitcoin reach $80,000 in August?" contract closed at 15:43:42 UTC on August 24, 2026, settling at 100c after a single one-minute Binance BTC/USDT candle printed a high at or above $80,000. This blog caught the same contract two days earlier at 45.35c, mid-crash and still very much a coin flip. What happened in between is less "bitcoin went up" than it looks: the contract resolved off one specific exchange's one- minute wick, hours before most broad price trackers agreed bitcoin had actually broken $80,000 for the day. Numbers below are from Gamma and the CLOB, fetched 2026-08-25 07:21 UTC.

From 91c to 42c to resolved, in four days

The shape by now is familiar to anyone who has followed this ladder on the blog: bitcoin broke $69,000 on August 20 as a Treasury bond-buyback announcement and a new SEC crypto framework triggered nearly $2 billion in liquidations, then ran another 15% to touch roughly $79,500 early Saturday, August 22 - just short of $80,000 - before a flash crash near 04:00 UTC that same morning wiped $1.8 billion in leveraged positions and sent the $80,000 contract from a 91.4c peak down to a 42.25c low by Sunday morning, August 23. That was where the last post left it: a genuine coin flip, needing roughly a 5% further run before month end. Bitcoin didn't need that long. Spot climbed through Monday, August 24 on continued Treasury- buyback optimism and fresh ETF inflows, and by mid-afternoon UTC the $80,000 contract was pricing near-certainty:

The $80,000 line stops dead just under 100c because the CLOB order book empties the moment a market closes - there is nothing left to quote once the outcome is decided. $82,500 keeps going: it was the next rung up on Saturday's spike and it's still an open question now, climbing from the low 20s straight through $80,000's resolution and into the low 70s as bitcoin pushes higher still.

One exchange, one candle, ten minutes to dispute

The contract's own rules are specific about what triggers it, and they matter more than they look: "This market will immediately resolve to 'Yes' if any Binance 1 minute candle for BTC/USDT during the month specified in the title... has a final High price equal to or greater than the price specified in the title." Not a daily close, not a composite index averaging several exchanges - one specific trading pair, on one specific exchange, sampled every sixty seconds. A wick that touches $80,000 for a single minute on Binance and immediately pulls back counts exactly the same as a sustained break above it. That is why the contract could resolve at 15:43 UTC on August 24 while several mainstream price trackers - reading composite or Coinbase-based feeds - were still describing bitcoin as trading in the high $70,000s well into the next morning. Different resolution sources, watching the same asset, don't always agree on when a threshold was crossed.

Once that candle printed, Gamma's own fields show the sequence: `closed` flips from `false` to `true`, `closedTime` records the exact halt (the `2026-08-24 15:43:42+00` above), `acceptingOrders` flips `false` so the book stops taking new resting orders, and `outcomePrices` freeze at `["1", "0"]` - the `1` marking Yes as the winner. `umaResolutionStatus`, null on every open market, flips to `"resolved"`. This contract's answer comes straight from the named price feed rather than a human's judgment call, so the proposal step is automatic - but it still runs through the same optimistic-oracle flow subjective markets use, `customLiveness` window included: 600 seconds, ten minutes, for someone to flag a bad print before the result locks in for good.

Everything still open moved the same direction

Bitcoin's August ladder is a stack of independent yes/no contracts, one per price level, so a resolution at one rung says nothing by itself about the rungs above it - except that this time, all of them kept climbing too:

BITCOIN - WILL AUGUST TOUCH...   PRICE    24H
$77,500                            100c   (resolved)
$80,000                            100c   (resolved)
$82,500                          72.50c  +34.15c
$85,000                          42.50c  +20.90c
$87,500                          23.00c  +10.50c
$90,000                          11.30c   +6.10c
$92,500                           5.40c   (n/a)
$100,000                          1.00c   -0.10c

$82,500 and $85,000 - both still coin-flip-adjacent territory a day ago - are now the ladder's live edge, up 34 and 21 points respectively in 24 hours. $90,000 has gone from a long shot to a genuine one-in-nine, and even $100,000, still priced under 2c, ticked lower rather than flat - the only rung on the board pricing in less room than it did yesterday, a reminder that "everything went up" is close to true here but not universally so.

Resolution isn't a payout - redemption is a separate step

Holding shares of the winning side when a market resolves doesn't put money in your wallet automatically. Each winning share is worth exactly $1 and becomes redeemable - a flag on the position, not cash - until an on-chain redemption transaction actually claims it. polymarket-tui surfaces that flag the moment it flips: a resolved position in the portfolio's positions table is marked won - redeem on web in amber, and pressing o on it opens the position directly on polymarket.com, where the redemption transaction is signed and sent. The client deliberately doesn't send that transaction itself - it's a read path for the price and an execution path for orders, not a wallet - so a $80,000 Yes position from this ladder now shows the flag rather than an order panel, since a resolved market takes no further orders to place.

From the terminal, not a dozen tabs

A ladder with eight independent rungs, one of which just resolved while the rest keep repricing, is hard to track by refreshing a single market page. In polymarket- tui, an event's full outcome table lists every rung's price and 24-hour move side by side, so a resolution shows up as one row locking to 100c while its neighbors keep moving - and once you're holding a winner, the portfolio screen flags it the same way, so there's no guessing whether a position is done trading or just quiet.
