What price will Bitcoin hit on May 20?

Market context

Bitcoin has spent May trading in the high-$70,000s, with recent market data clustering around the $76,000-$78,000 band. That makes a May 20 settlement above much of the higher strike ladder look unlikely, which fits the current 0% YES price on this market. For comparison, Polymarket has shown Bitcoin’s May 20 market anchored almost entirely in the $76,000-$78,000 bucket, while Robinhood’s related event has quoted tiers such as $76,600 or above at 99¢ and higher thresholds progressively cheaper. These books are not directly comparable on structure: Polymarket expresses straight implied probabilities, Robinhood sells contract prices in cents, and Kalshi-style venues typically add clearer fee disclosure and broader US KYC gating than offshore books.

The main watchpoints are Bitcoin’s own technical levels and any flows from large corporate buyers. 24/7 Wall St. said earlier in the month that $80,000 and the 200-day moving average near $82,228 were the key resistance levels, with a break needed to shift the range. Changelly’s near-term forecast has also kept BTC clustered around $80,000, implying only modest upside into late May. On the event date itself, the settlement uses CF Benchmarks’ real-time index, so the final print matters more than spot chatter; that is why even a brief move through a threshold can flip a close in the last window. Strategy’s earnings and any comment on continued Bitcoin buying are the clearest scheduled catalyst still capable of moving the odds.

Methodology

This page compares What price will Bitcoin hit on May 20? specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. Live odds come from the Polymarket order book; the other venues' contract details are maintained manually because their APIs aren't directly comparable. Every CTA routes to PolyGram, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). PolyGram routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
