Market probability: 91%. 9% Market Probability 1h -13.0% 24h -41.0% Trend Strong (77/100) Volume $72.2K $72.2K in 24h Liquidity $23.2K Moderate depth Time Left 20 hours Resolves Jul 28 72K Vol. Jul 28, 2026 1H 6H 1D 1W 1M ALL Select lines to display Bitcoin Up or Down on July 28? $75K Vol. 9% Yes 9¢ No 91.5¢ Bitcoin entered July 28 carrying significant downward momentum, with the prediction market pricing only a 9 percent chance that Bitcoin closes the day in positive territory. That number reflects a market that has largely made up its mind: a single trading session is unlikely to reverse the pressure bearing down on Bitcoin right now. The asset’s spot price, the funding-rate environment, and the weight of same-day volume all point in the same direction. The market question asks whether Bitcoin finishes July 28 higher than its opening price. The YES outcome carries a 9 percent implied probability, and the NO outcome sits at 91 percent. The contract resolves at 4:00 PM UTC on July 28, 2026. Lifetime trading volume stands at $72,157, with $72,155 of that arriving in the last 24 hours, which means nearly all activity on this contract is fresh and concentrated. Sponsored Partner How the Bitcoin Up or Down on July 28 Contract Works The YES outcome pays out if Bitcoin’s price is higher at the 4:00 PM UTC close on July 28 than at the session open. The NO outcome pays out if Bitcoin is flat or lower at that same close. Resolution uses the market’s designated price source at the exact cutoff time. YES (Bitcoin closes higher on July 28): 9 percent implied probabilityNO (Bitcoin closes flat or lower on July 28): 91 percent implied probability For the NO outcome to pay out, Bitcoin simply needs to avoid gaining ground by 4:00 PM UTC. A sideways session counts. A modest dip counts. Only a confirmed positive close on the session flips the outcome against the 91 percent favorite, and given the momentum composite right now, that is a narrow path. Market Signals: Heavy Volume and a Decisive Lean The momentum composite here is unambiguous. The 1-hour price change on the contract is flat at 0.0 percent, the 24-hour change on the contract is down 28.0 percent, and the trend score sits at 61.40, which is moderately elevated but operating inside a clear downtrend. That combination reads as deceleration in the selling, not recovery. The most obvious crypto catalyst is Bitcoin’s own spot-price action: any session where Bitcoin opens weak and struggles to reclaim intraday levels pushes this contract’s NO probability even higher. Lifetime volume is $72,157, with $72,155 arriving in the last 24 hours. That near-total same-session concentration signals that traders rushed into this contract today rather than building positions over time. Liquidity stands at $23,249, which is thin for a one-day directional market. Thin order books can amplify moves in either direction, but the current directional lean is too lopsided for that to matter much unless a sharp spot reversal materializes before the 4:00 PM cutoff. Key Factors Bitcoin’s spot-price trend entering July 28 is bearish, and the contract’s 91 percent NO probability reflects that the market sees no catalyst strong enough to flip a full-session gain.The 24-hour contract price change of negative 28 percent confirms aggressive positioning toward the NO outcome across the trading day.Liquidity at $23,249 is thin, meaning late-session spot volatility could move the contract price sharply even on modest volume.Same-day concentration of $72,155 in 24-hour volume out of $72,157 total signals fresh, conviction-driven positioning rather than accumulated market-making activity.The trend score of 61.40 inside a falling contract price suggests deceleration in contract selling, not a reversal toward YES territory. Lines Analysis: Bitcoin and the Weight of the Session Bitcoin’s session dynamics support the NO outcome on several levels. When nearly all contract volume arrives in a single day and the probability lands at 91 percent, the market is expressing a clear directional view backed by real capital. The spot-price weakness carrying into July 28, combined with a funding-rate environment that has been tilting negative in recent sessions, gives traders little reason to expect a clean positive close. Bitcoin tends to follow through on intraday momentum during sessions without a major macro catalyst, and no major scheduled event appears capable of reversing that pressure before the 4:00 PM UTC resolution. The YES outcome remains live at 9 percent, and that is not a trivial residual. Bitcoin is a volatile asset, and a sudden ETF inflow print, a surprise macro headline, or a short-squeeze cascade on derivatives markets could push Bitcoin into positive territory before the close. The specific level to watch is whether Bitcoin can reclaim its session open price with enough time left before 4:00 PM UTC to hold the gain. A reversal that stalls or fades before the cutoff still resolves as NO. Signals to Monitor Bitcoin’s spot price relative to the July 28 session open is the single most direct input into this contract’s resolution, and any move above that level deserves immediate attention.Coinbase and Binance perpetual funding rates turning sharply positive would signal short-covering pressure that could push Bitcoin into green territory for the session.U.S. equity futures and macro risk sentiment in the hours before the 4:00 PM UTC close are relevant, since Bitcoin has tracked risk-asset moves closely in recent sessions.Exchange inflow spikes on Coinbase or Binance before the close would increase selling pressure and reinforce the NO outcome.CME Bitcoin futures open interest shifts in the final hours before resolution can amplify or dampen spot moves, particularly if large positions unwind near the cutoff. The contract’s lifetime volume of $72,157 is modest, and the directional lean at 91 percent NO is supported by that same-day volume concentration. Thin markets can flip, but flipping requires a catalyst that the current session’s data does not yet show. The data favors NO. LINES VERDICT Bitcoin Down on July 28 The capital in this contract is nearly unanimous, and the spot-price momentum entering the session gives the YES outcome almost no runway to close the gap before resolution. What the market says: The NO outcome carries a 91 percent implied probability, reflecting near-consensus that Bitcoin does not close July 28 in positive territory. The contract resolves at 4:00 PM UTC, leaving only a narrow window for a spot reversal to change the outcome. Thin liquidity means late-session volatility could briefly move the contract price, but the directional lean has not shifted.

Frequently Asked QuestionsWhat does the 91 percent NO probability mean for this contract?It means traders have priced a 91 percent chance that Bitcoin does not close July 28 higher than the session open. The remaining 9 percent reflects the probability that a spot reversal pushes Bitcoin into positive territory before 4:00 PM UTC.How does the NO outcome pay out on this contract?The NO outcome pays out if Bitcoin's price is flat or lower at the 4:00 PM UTC close on July 28 compared to the session open. A sideways session is enough. Bitcoin does not need to fall for NO to resolve in traders' favor.What could move this contract's probability before resolution?A sudden Bitcoin spot-price rally above the session open, a positive ETF inflow print, or a short-squeeze on derivatives markets could push the YES probability higher. Sustained selling pressure or macro weakness reinforces the NO outcome.When and how does this market resolve?The contract resolves at 4:00 PM UTC on July 28, 2026, using the market's designated price source at that exact cutoff. The outcome is determined solely by whether Bitcoin's price is above or below the session open at resolution time.Is the volume and liquidity on this contract reliable?Lifetime volume is $72,157 and liquidity is $23,249, both on the thin side. Nearly all volume arrived in the last 24 hours. Thin liquidity can amplify late-session price swings, so the contract price may move sharply on modest spot action near the close.How is the Smart Money Index calculated?We aggregate the live positions of the top 50 Polymarket whales (ranked by 30-day tracked volume) into one composite reading per market.

Bitcoin Supporting Factors for YES A sudden surge in Bitcoin spot demand, driven by an unexpected ETF inflow print or a macro risk-on catalyst, could push Bitcoin above its session open before 4:00 PM UTC. A short-squeeze on derivatives markets, where forced buying accelerates price recovery, is the most plausible path to a YES resolution. The thin liquidity on this contract means even modest spot momentum could shift the implied probability quickly. Bitcoin Risk Factors Reinforcing NO Continued spot-price weakness heading into the July 28 session, combined with negative funding rates on major perpetual exchanges, keeps selling pressure elevated. An exchange inflow spike on Coinbase or Binance before the close would add fresh selling supply and push Bitcoin further from reclaiming its session open. Any U.S. macro data release that surprises to the downside reinforces the NO outcome. YES Comeback Scenario A sharp reversal in Bitcoin's spot price, triggered by a geopolitical de-escalation or a surprise Federal Reserve communication, could produce a positive session close. The 9 percent residual probability captures exactly this kind of low-likelihood event. For YES to resolve, Bitcoin must not only recover to the session open but hold that gain through 4:00 PM UTC without fading in the final hour. Wildcard Factor An unexpected large-scale exchange event, such as a major platform outage, a whale liquidation cascade, or a sudden regulatory headline affecting U.S. crypto markets, could produce extreme intraday volatility before the 4:00 PM UTC close. In a thin-liquidity contract environment, that kind of shock could briefly move the implied probability in either direction before the spot market stabilizes. Key macro factor: Bitcoin's correlation with U.S. equity risk sentiment remains elevated, meaning any late-session macro surprise before the 4:00 PM UTC resolution could produce a sharp directional move that overrides the current NO consensus.
