Market context
Bitcoin needs to finish the settlement window above the relevant strike for this market, and the current crowd-implied 0% YES suggests traders see that outcome as very unlikely at the prevailing price level. Spot Bitcoin was around $65,000-$66,000 in early trading on 23 July, with Yahoo Finance reporting an opening of $66,081.05 and a move to $65,054.55 by 9:22 a.m. ET, which places it well inside the band where most published short-term forecasts cluster.[8][10]
The comparison with Polymarket is useful because its contract is quoted as a range outcome, with the leading bucket on its “Bitcoin price on July 23?” market at 96% and the next at 3%, whereas Kalshi-style books usually express the same event in implied probability and Betfair or Smarkets in decimal odds, so the same view can look less extreme once fees are included.[2] Outside prediction markets, several forecast sites still place July-end Bitcoin in the mid-$60,000s to low-$70,000s, including CoinCodex at $66,709 for 23 July and Coinspeaker at $66,498.69 on 22 July, which helps explain why a 0% YES price is more a statement about this exact strike than about Bitcoin direction overall.[5][10]
For traders, the main catalysts are macro headlines and crypto-specific flows rather than a single scheduled Bitcoin event. A July outlook piece highlighted the mid-July inflation report, ETF inflows, and the Fed meeting on 28-29 July as the key dependencies, with resistance around $66,600-$67,600 and downside support near $58,200-$58,500.[11][9] On competing books, KYC reach also matters: Polymarket and Kalshi are account-gated and cash-settled, while Betfair and Smarkets typically require broader betting-style onboarding and levy different commission structures, so after-fee returns can diverge even when the quoted probability or odds point to the same view.
Methodology
We read What price will Bitcoin hit on July 23? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.
Resolution & payout
Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.
Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
FAQ
- Polymarket vs Kalshi — which is better?
- Depends on your location. Kalshi is CFTC-regulated, US-only with full KYC. Polymarket is global, on-chain, no KYC up to $1,500. Polymarket has ~10x higher liquidity but higher regulatory risk.
- Which platform has the deepest liquidity?
- Polymarket — by a wide margin. Top markets reach $50-500M volume, Kalshi ~$200M cumulative, Betfair similar. Deeper liquidity means your trade moves the quote less.
- What about Smarkets as an alternative?
- Smarkets is a UK betting exchange with a lower default commission (2%) than Betfair. Liquidity on political markets is below Polymarket, comparable to Kalshi. Geo-blocked in many jurisdictions.
- Which platform is accessible globally?

- Which platform supports Klarna/SOFORT?
- Directly: none. Polymarket accepts only USDC on Polygon. Robinhood Prediction Markets offers a fiat on-ramp via Klarna or SOFORT (DE/AT/CH) and converts internally to USDC for the Polymarket order book. T+1 processing.
