Predictive Markets Daily (Issue 15 · Week 30, 2026)

01Popular Prediction Market Events

With July 21, 2026, as the data benchmark date, Polymarket predicts that market enthusiasm will continue to rise, with macroeconomic policies and sports events becoming focal points of capital competition. Although the price prediction market for cryptocurrencies themselves did not rank among the top five in terms of trading volume on that day, the fluctuations in odds in major macro markets significantly influence the pricing logic of risk assets.

High-confidence events: Solidified expectations of Federal Reserve rate cuts

• Fed Decision in July?: The probability of a "Yes" answer is as high as 92.7%, with 24-hour trading volume reaching $3327.0K. There is a strong consensus in the market that the Federal Reserve will make a specific decision on July 29, 2026 (usually referring to a rate cut or continuation of accommodative policies). This high level of confidence reduces the premium associated with macroeconomic uncertainty, providing stable liquidity expectations that support the crypto market.

Controversial events: Geopolitics and sports competitions

• Ballon d'Or Winner 2026: The probability of a "Yes" answer is 38.8%, with 24-hour trading volume of $3925.7K, making it the most popular option. The market has spread its bets among multiple candidates, indicating high uncertainty regarding the outcome.
• Will the U.S. invade Iran before 2027?: The probability of a "Yes" answer is 26.5%, with 24-hour trading volume of $766.1K. While there is a geopolitical risk premium, there is no widespread panic; the "No" option dominates, suggesting that the market believes the likelihood of large-scale military conflicts in the short term is low.
• Baltimore Orioles vs. Boston Red Sox: The probability of a "Yes" outcome is 57.5%, with a 24-hour change of +16.0 percentage points. The sports betting market is highly volatile, with short-term capital flows significantly affecting odds and reflecting rapid shifts in retail investor sentiment.

Analysis of indirect impacts on the crypto market

None of the top 5 most popular events on that day were directly related to BTC/ETH price prediction markets, but macro odds have a spillover effect on crypto assets:

1. Liquidity expectations: The 92.7% probability of a "Yes" answer in the Federal Reserve decision market reinforces expectations of accommodative policies, which is beneficial for risk assets such as BTC (current price: $65,481.00) and ETH (current price: $1,913.69).
2. Intensifying platform competition: Hyperliquid is incentivizing developers to deploy prediction markets through its HIP-4 proposal, requiring them to stake 500,000 HYPE tokens, in an effort to compete with Polymarket. This competition at the infrastructure level may improve the overall liquidity and efficiency of on-chain prediction markets, indirectly boosting activity within the crypto ecosystem.
3. Regulatory risks: France’s blockade of access to Polymarket and ongoing insider trading investigations highlight compliance risks, which may drive some funds to more decentralized or better-compliant platforms, affecting short-term market sentiment.

03Odds Analysis and Market Interpretation

Reference Date: 2026-07-21

Federal Reserve’s July Decision: High Confidence in Rate Cuts

Data from Polymarket shows that the probability of a “Yes” outcome for the “Fed Decision in July?” option is as high as 92.7%. Although there was a 24-hour change of -0.3 percentage points, the outstanding contract volume of $13,832.0K indicates strong consensus among investors regarding this outcome. Such a high implied probability means the market has almost fully priced in the expectation of the Federal Reserve adopting easing policies on 2026-07-29.

• Betting Logic: The case for betting “Yes” is based on the support that increased macro liquidity will provide to risk assets. With BTC currently trading at $65,481.00 and a 24-hour gain of +1.5%, it appears that investors have already reacted positively to these developments. Betting “No” represents a low-probability contrarian strategy, which only makes theoretical sense in the event of sudden geopolitical shocks leading to inflationary rebounds.
• Market Connection: This pricing pattern provides strong support for the current trends in the crypto market. The stability of BTC’s market cap at $1,313B, along with ETH’s price rising by +2.3% to $1,913.69, both demonstrate how expectations of liquidity play a crucial role in supporting major cryptocurrencies.

Geopolitical Risks: Reduced Probability of U.S. Invasion of Iran

The probability of a “Yes” answer to the question “Will the U.S. invade Iran before 2027?” is 26.5%, with a 24-hour decline of -3.5 percentage points, and outstanding contracts amounting to $7,038.2K. This significant drop in probability suggests that short-term geopolitical tensions have eased, reducing investors’ fears of extreme conflicts breaking out.

• Betting Logic: The reasoning behind betting “No” lies in the tendency of probabilities to return to their average levels and the increasing use of diplomatic solutions. The current 26.5% probability offers a favorable odds structure. Betting “Yes” requires betting on sudden military action; given the 24-hour trading volume of $766.1K, some speculative funds are still taking bets on such tail risks.
• Market Connection: A reduction in geopolitical risks has a moderately positive impact on the crypto market. If the probability of conflict continues to decline, capital seeking safety might flow back into risk assets, helping to keep BTC above the $65,481.00 price level.

Fluctuations in Sports Betting Odds: Sharp Changes in MLB Odds

Odds for various MLB games have seen significant fluctuations. For example, the probability of a “Yes” outcome in the “Baltimore Orioles vs. Boston Red Sox” game increased by +16.0 percentage points to 57.5%, while in the “Pittsburgh Pirates vs. New York Yankees” game, it decreased by -36.0 percentage points to 10.5%. Such sharp divergences reflect strong disagreements among short-term investors regarding the performance of specific teams.

• Betting Logic: Betting “Yes” (for the Orioles) is driven by recent performance or injury updates, with a 57.5% probability indicating market preference for their victory. Betting “No” (for the Yankees) relies on the extremely low 10.5% probability, representing a high-odds longshot bet.
• Market Connection: Such high-frequency trading activities have little connection to crypto market trends and mainly reflect liquidity dynamics within prediction markets. It’s worth noting that Kalshi accounted for 73% of market share during the World Cup, suggesting that traditional sports betting capital is accelerating its shift toward compliant prediction platforms, which could potentially draw away some of Polymarket’s liquidity.

Overall Market Sentiment Assessment

Current sentiment in prediction markets exhibits a structurally bullish trend. On a macro level, the high certainty of Federal Reserve rate cuts (92.7% probability of a “Yes” outcome) provides solid liquidity expectations for crypto assets, supporting steady gains for BTC and ETH. Geopolitically, the declining probability of conflicts (26.5% probability of a “Yes” outcome) reduces systemic risk premiums. Despite the volatility in sports-related markets, key macro indicators suggest that investors are more inclined to bet on asset appreciation during an easing economic cycle rather than seeking safety.

04Operation suggestions

Operational Recommendations

1. Event-Driven Defense: Avoiding Regulatory and Insider Trading Risks

• Key Data: Approximately $200 million in transactions on Polymarket in the first half of the year were suspected of involving insider trading, and French regulators ordered ISPs to block the platform.
• Triggers: New regional access restriction announcements for major prediction market platforms like Polymarket, or law enforcement actions by regulators targeting insider trading in prediction markets.
• Execution Criteria: Adopt a moderate defensive approach by gradually reducing exposure to centralized or semi-centralized prediction market platforms, avoiding over-concentration of funds in contracts that may face compliance-related shutdowns.
• Time Frame: This month

2. Liquidity Rotation Strategy: Focusing on Staking Needs in High-Barrier Ecosystems

• Key Data: Hyperliquid introduced the HIP-4 proposal, requiring 500,000 HYPE (approximately $300 million) in staking for prediction market deployments, along with $32 million in incentives.
• Triggers: Significant fluctuations in the spot price of HYPE, or on-chain data showing large amounts of HYPE being locked to meet staking requirements.
• Execution Criteria: Build positions in phases, being mindful of potential liquidity constraints for HYPE tokens due to high staking demands, while also being cautious about reduced ecosystem activity resulting from these high barriers.
• Time Frame: Next 2 weeks

3. Sentiment-Reversal Strategy: Taking Advantage of Market Panic to Sell Profits

• Key Data: The market sentiment index dropped sharply by 15.6 points to 36.2 (Fear level), while Whale activity on the chain increased by 46 points.
• Triggers: If the support level below the current BTC price of $65,481.00 holds, and Whale addresses continue to show net inflows rather than sales.
• Execution Criteria: Increase positions appropriately by taking advantage of mispriced opportunities caused by market panic, establishing a foundation during periods when Whales are accumulating assets, rather than blindly chasing higher prices.
• Time Frame: This week

Risk Warnings

• Regulatory Compliance Risks: Polymarket is facing ISP blocks in France and insider trading investigations. Intensified regulatory actions could lead to sudden liquidity shortages or freezing of user assets.
• Data Manipulation Risks: Over half of the wallets involved in suspicious activities were created within 24 hours before the trades, and 71% of the funds came from U.S.-regulated exchanges, indicating highly professional insider trading tactics that make it difficult for ordinary investors to detect abnormal price signals.
• Intensifying Ecosystem Competition Risks: Kalshi dominates Polymarket with a 73% share, while Hyperliquid enters the market with substantial incentives, leading to rapid fragmentation in the industry. Token values of platforms that were invested in early on may decline due to loss of market share.
