01Popular Prediction Market Events

As of the data benchmark date of 2026-08-04, Polymarket predicts that market enthusiasm will continue to rise, with significant trading volume for major events.

Highly Certain Events

• St. Louis Cardinals vs New York Yankees: Probability of “Yes” is 92.5%, with 24h trading volume of $1189.4K. There is strong market consensus that the Cardinals have a very high chance of winning.
• Bitcoin Price Prediction: Probability of “Yes” is 93.3%, with 24h trading volume of $1021.3K. The market believes it is almost certain that BTC will exceed a specific threshold on 2026-08-04 (based on the current price of $63,316.00).
• Pittsburgh Pirates vs Milwaukee Brewers: Probability of “Yes” is 89.5%, with 24h trading volume of $515.7K. The Brewers are considered favorites to win.

Divided Opinions and Macro Events

• Resumption of Traffic in the Strait of Hormuz: Probability of “Yes” is 13.5%, with 24h trading volume of $1122.9K. The market believes the likelihood of normal traffic resuming by 2026-08-31 is extremely low, with geopolitical risk premiums remaining.
• United States Invading Iran: Probability of “Yes” is 21.5%, with 24h trading volume of $780.7K. The market generally views the possibility of military conflict before 2027 as low.
• Federal Reserve Decision in September: Probability of “Yes” is 42.5%, with 24h trading volume of $582.3K. There is disagreement in the market regarding interest rate cuts or policy shifts, indicating high underlying uncertainty.

Indirect Impact on the Crypto Market Although the main themes in the broader macro markets are sports and politics, the low probability of traffic resumption in the Strait of Hormuz (13.5% for “Yes”) suggests ongoing geopolitical risks, which could support demand for safe-haven assets. Meanwhile, the high certainty in Bitcoin price predictions (93.3% for “Yes”) indicates strong support at short-term price levels. This aligns with the current BTC price of $63,316.00 and its active 24h trading volume of $25.4B, demonstrating the resilience of the crypto market amid macroeconomic uncertainties.

Reference Date: 2026-08-04

Expectations for the Restoration of Traffic in the Strait of Hormuz

Data from Polymarket shows that the probability of traffic returning to normal in the Strait of Hormuz by 2026-08-31 is only 13.5%, with an open interest of $4035.5K. The low implied probability indicates extreme market pessimism—those betting “Yes” expect rapid de-escalation of geopolitical tensions, while those betting “No” are based on the logic of ongoing tensions. This contradicts the situation on 2026-08-03, when the probability of WTI oil prices falling below $75 rose to 77%, suggesting that the drop in oil prices was more driven by the reduction in risk premiums rather than geopolitical easing, exerting a slightly bearish pressure on crypto market liquidity.

Expectations of a Federal Reserve Rate Cut in September

The probability of a “Fed Decision in September?” outcome being “Yes” is 42.5%, with 24-hour trading volume at $582.3K. Nearly half of the implied probabilities reflect market divergence regarding the Federal Reserve’s policy shift. Those betting “Yes” are based on expectations of cooling inflation data, whereas those betting “No” are concerned that persistent inflation will force maintaining high interest rates. The current BTC price is $63,316.00, up slightly by 0.1%, indicating that the hedging property of crypto assets weakens amid macroeconomic uncertainty, which aligns with the ambiguity surrounding Fed decision expectations.

Possibility of the U.S. Invading Iran

The probability of “Will the U.S. invade Iran before 2027?” being “Yes” is 21.5%, with an open interest of $8005.6K. A 21.5% probability suggests that the market believes the likelihood of military action is low but not zero. Those betting “Yes” are worried about geopolitical escalation leading to black-swan events, while those betting “No” believe diplomacy should take precedence. Such an event would have a severe impact on global risk assets. Currently, the low probability provides some margin of safety for the crypto market, but the high open interest shows that tail risks remain under close attention.

Overall Market Sentiment

The current prediction market exhibits bearish sentiment. Negative expectations related to geopolitics (Hormuz, Iran) are priced highly, and the uncertainty surrounding Federal Reserve policies remains unresolved. Although BTC prices have stabilized, macro-level pessimistic factors—such as the decline in risk appetite reflected by plummeting oil prices—dominate the pricing logic. Investors are cautious about significant short-term price increases.

04Operation suggestions

Operational Recommendations

• Event-driven Strategy: Robinhood predicts market revenue to reach $156 million, accounting for 20% of total income. If there are no major negative regulatory developments by August 4th, it is advisable to build positions in relevant ecosystem tokens in phases this week to capitalize on the shift in business focus.
• Macro-risk Hedging: Polymarket estimates the probability of WTI oil prices falling below $75 by August at 77%. If oil prices decline as expected, boosting risk-aversion sentiment, consider increasing BTC holdings moderately over the next two weeks to hedge against volatility in equity assets.
• Liquidity Monitoring: July is projected to see total market trading volume reach $50.6 billion, setting a new record high. If weekly trading volumes shrink by more than 10% on a sequential basis, it is prudent to gradually reduce positions in highly volatile small-cap tokens within this month to avoid liquidity crunch risks.

Risk Warnings

• Regulatory Uncertainty: Kalshi is facing lawsuits in New York, with the industry’s regulatory status still unresolved. Should a federal-level compliance ban be imposed, the market for such tokens could experience a systematic valuation correction.
• Extreme Sentiment Reversal: The market sentiment index once dropped by 15.6 points, entering a fearful territory. If the index falls below 40 again, be alert to potential panic selling that could trigger chain reactions of liquidations.
• Disappearance of Geopolitical Premium: The probability of normal traffic resuming in the Strait of Hormuz is only 13.5%. If geopolitical tensions ease unexpectedly, energy-related crypto assets may face rapid loss of their premium value.
