Bitcoin briefly reclaimed $65,000 on the evening of July 27, then gave nearly all of it back overnight. Polymarket's daily market asking whether BTC closes above $64,000 at noon ET today swung from an 86.5c high on the morning of July 27 to 20c now, tracking a fall to roughly $63,200 - crypto press puts BTC down about 2.5-2.8% on the day and 4.6% on the week. The reversal landed the same week global liquidity is tightening into Wednesday's Fed decision, and it wasn't Bitcoin alone: South Korea's KOSPI fell 8% and Japan's Nikkei more than 4% the same day. Numbers below are from the Gamma and CLOB APIs, fetched 2026-07-28 09:16 UTC.
01The board right nowToday's cutoff, and the wider range around it
"Bitcoin above ___ on July 28?" is one event split into a strike ladder that all resolves the same way: Yes if the Binance BTC/USDT 1-minute candle at 12:00 noon ET today closes above the price in the title. Three strikes bracket where the action is:
ABOVE ___ AT NOON ET (JUL 28) PRICE 24H
$62,000 97.2c -0.9c
$64,000 20.0c -61.5c
$66,000 0.5c -24.0c
A market that priced an above-$64,000 close as an 86.5c near-lock yesterday morning now prices it as a 1-in-5 shot, with about seven hours left before it settles. The $62,000 strike barely moved - it was never in serious doubt - while $66,000 has gone from a live possibility to a near-zero.
02What changedA reclaim, then a reversal
Bitcoin spent the back half of July 26 grinding around $65,000-66,000, comfortably above the $64,000 line, and pushed further into the mid-$66,000s by the morning of July 27. Crypto-market coverage on July 28 attributed the overnight reversal to a cluster of pressures landing at once: tightening global liquidity and rising Treasury yields ahead of the Federal Reserve's policy decision (the FOMC's two-day meeting started today, with the rate call due July 29), a reported reversal in spot Bitcoin ETF flows to net outflows, and cascading forced liquidations in derivatives markets once price broke below its recent support. Coverage also pointed to a longer-run supply overhang - on-chain transfers tied to German government wallets and pending Mt. Gox creditor distributions worth roughly $9 billion - and smaller mining operations facing post-halving pressure to sell. None of that is visible in the Polymarket price on its own; what the price shows is that the market absorbed all of it within a single overnight window. By the morning of July 28, Ethereum had fallen a sharper 3.5% to about $1,872, and the crypto-wide Fear & Greed Index had slipped to 29 ("Fear").
03The repricingUp 24 points in a day, down 66 points that night
The shape is two clean moves rather than one long drift. Through July 26 the price chopped in the low 60s as BTC hovered just above $64,000, then climbed almost in a straight line from 65.5c at 9pm that night to an 86.5c peak by 7am on July 27 as Bitcoin pushed into the mid-$66,000s. It held in the 80s for most of July 27 daytime - including a brief wobble to 70.5c around 3-4pm that fully recovered by evening - before falling off a cliff starting at 11pm: 43.5c within the hour, 18.5c by 3am July 28, a small bounce, and 20c now. Almost the entire day's repricing happened in a single five-hour window overnight.
04The rest of July's rangeA fresh high looks done; a fresh low doesn't
Alongside the daily ladder, a separate event prices whether Bitcoin touches specific highs or lows at any point before July ends - a 1-minute Binance candle crossing the strike resolves it Yes immediately, no matter what happens afterward:
TOUCHES IN JULY (ANY POINT) PRICE 24H
Reaches $67,500 (high) 7.0c -27.5c
Reaches $70,000 (high) 1.75c -3.6c
Dips below $62,500 (low) 66.5c +39.1c
Dips below $60,000 (low) 16.5c +11.5c
With three trading days left in the month, the market has all but priced out a fresh July high above $67,500 - it was a 34.5c shot a day ago, now 7c - while a dip below $62,500 has gone from a 27.6c long shot to 66.5c, a better-than-even bet, in the same 24 hours. That is the crash in a different frame: not just "will noon-ET today print above $64,000" but "has the month's high already happened, and is a new low still coming."
05The book behind the priceA four-cent market with a gap just behind it
The above-$64,000 book quotes an 18c bid against a 22c ask - four cents wide for a market that moved 66 points overnight, with about $3 of notional on the bid and $12 on the ask at the literal touch. One tick further out, the book thins further: the next ask sits at 23c for 5 shares, then jumps straight to 35c. A market pricing a 1-in-5 chance with under seven hours to resolution can still have almost nothing resting near its own quote; a marketable order of any real size would walk straight through the gap to 35c before finding depth again.
06Watching a fast market like thisA ladder and a calendar, one screen
A crash like this spans two different event types at once - a same-day strike ladder settling in hours, and a whole-month high/low ladder settling whenever a level trades, if it trades at all. Tracking both by hand means juggling two web pages. In polymarket-tui, opening either event lists every strike with its live price and 24-hour move in one table, and drilling into any single market shows its order book and price history inline.
