The Bitcoin June 2026 high ladder resolved with its top already behind it. Bitcoin's monthly high, $73,742 on Coinbase Exchange, printed in the first hour of June 1 Eastern time, before either venue listed its rungs, and the price slid to $58,524 by the June 30 close. Every Kalshi rung from $75,000 to $92,500 and every full-month Polymarket rung from $72,500 to $100,000 settled No on July 1, 2026.
Resolved July 1, 2026.
Bitcoin's June 2026 high came in the first hour of the month, and nothing after it came close. Coinbase Exchange data puts the peak at $73,742 just after midnight Eastern on June 1. By June 30 Bitcoin closed at $58,524, down about 20% on the month, and every full-month upside rung on Kalshi and Polymarket settled No. When the engine began tracking the board on June 2, Polymarket still priced the $72,500 rung at 74% and both venues had the $75,000 rung near 50%.
The month's high on Coinbase Exchange was $73,742.00, in the hour that began at 12:00 AM ET on June 1. The June 1 daily candle shows $73,978.52, but that candle runs on UTC and its top printed on the evening of May 31 Eastern time, outside the contract window. The month's low was $58,000.00 on June 25.
Kalshi ran the ladder as its KXBTCMAXMON series, with eight rungs from above $75,000 to above $92,500. All eight finalized No at 12:38 PM ET on July 1, 2026, on about 1.79M contracts traded. Kalshi's rungs listed at 8:02 AM ET on June 1 and settle on a trimmed mean of the CF Benchmarks Bitcoin Real Time Index, so the overnight top never counted.
Polymarket's "What price will Bitcoin hit in June?" event drew $34.9M: $17.2M on upside rungs and $17.7M on dip rungs. Its full-month upside rungs, $72,500 through $100,000, settled No in the early hours of July 1. The $72,500 rung listed around 10:38 AM ET on June 1, after Bitcoin had already slipped below that level on Binance, Polymarket's resolution source. One upside contract did pay: a $65,000 rung Polymarket relisted on June 4, which counts only trading after its listing, resolved Yes on the evening of June 14. A second $65,000 relist, opened June 25, settled No.
The June ladder was decided in the first week. Daily Coinbase candles show the slide:
No session after June 1 traded above $71,316, so every rung from $72,500 up stayed out of reach for the last 29 days of the month.
The engine's daily closes for the most-watched rungs:
| Date | Polymarket $72,500 | Polymarket $75,000 | Kalshi $75,000 |
| Jun 2 | 74% | 50% | 50% |
| Jun 6 | 13% | 8% | 11% |
| Jun 15 | 21% | 10% | 12% |
| Jun 23 | 1% | 1% | 2% |
| Jun 30 | 0% | 0% | no data |
The opening prices were the miss. On June 2 the board treated $75,000 as a coin flip even though the month's best price was already behind it and Bitcoin was falling. Traders corrected fast: by June 6 the $75,000 rung was down to single digits on Polymarket and 11% on Kalshi. The June 15 rebound lifted the $72,500 rung back to 21% before the late-month slide finished it off. The engine's history for the Kalshi $75,000 leg ends on June 24 at 2%. The far-tail $100,000 rung, which drew $3.47M on Polymarket, never closed above 1%.
The two venues tracked each other within a few points on the shared $75,000 rung, and they settled every shared rung the same way.
The next month ran the same structure. The Bitcoin July 2026 high ladder topped out at $66,924 on July 21, so only its $65,000 rung paid. A separate Polymarket contract on Bitcoin reaching $150,000 by June 30, 2026, which drew $22.1M, also settled No on July 1.
The longer-dated boards are still open. The How High Will Bitcoin Get in 2026 odds and the Bitcoin 2026 low ladder settle on the full calendar year, and the Bitcoin price at the end of 2026 board prices where the year closes. For the six-figure question, the Bitcoin $100K market tracks when Bitcoin gets back there. More boards live on the crypto markets hub.
Each rung is a separate one-touch contract on Bitcoin's highest price in June 2026. On Kalshi (KXBTCMAXMON), a rung resolved Yes if, at any minute after the market was issued and through 11:59 PM ET on June 30, 2026, a trimmed mean of the CF Benchmarks Bitcoin Real Time Index (minute-by-minute values with the top and bottom 20% removed) was above the strike; if CF Benchmarks data was unavailable, affected strikes resolve No. On Polymarket, a rung resolved Yes if any Binance BTC/USDT one-minute candle during June (12:00 AM ET June 1 through 11:59 PM ET June 30) had a High at or above the strike; relisted rungs marked "from" a June date count only price action after their listing. Each Yes rung pays $1 per share and each No rung pays $0. Settlement: Kalshi finalized all eight rungs, above $75,000 through above $92,500, as No at 12:38 PM ET on July 1, 2026, and Polymarket resolved its full-month rungs from $72,500 through $100,000 as No in the early hours of July 1, 2026, with its June 4 relist at $65,000 resolving Yes on June 14.
