The USA favored over Belgium in World Cup round of 16 match?

The provided article text does not contain a factual match report or betting-market analysis on whether the USA is favored over Belgium. Instead, it includes general disclaimers about gambling risk, eligibility and regulatory differences for prediction markets, and promotional notes about how media entities may earn revenue from betting referrals. It also states that betting legality varies by location and that odds can change minute to minute. Because the content does not include specific odds, predictions, teams’ recent results, venues, or dates tied to a Belgium–USA World Cup round-of-16 matchup, no match-related figures can be summarized reliably. The underlying event context referenced in the title is not supported by details in the supplied body text.
