Tampere: Daniel Galan vs Gilles Arnaud Bailly

Platform comparison

Market context

Gilles-Arnaud Bailly has already secured victory over Daniel Galan in the Tampere Challenger, defeating the Colombian 7-6, 6-2 in their first-round match on 20 July 2026. The 20-year-old Belgian fourth seed, ranked 266th on the ATP, overcame Galan (ATP 287), who entered the tournament as an alternate, in a contest lasting 1 hour 44 minutes [1]. This result confirms the market’s current 0% YES probability for Galan advancing, as the match has been completed with Bailly as the clear winner.

Historically, prediction markets on tennis matches that resolve post-match completion with a definitive winner show near-zero volatility once results are confirmed, mirroring cases where early-set retirements or straight-set victories eliminate uncertainty. Comparable outcomes in Challenger-level events, particularly when a higher-ranked seed faces an alternate, consistently produce decisive results that align with pre-match odds, reinforcing the reliability of the 0% settlement for Galan in this instance.

Traders should note that Bailly’s next fixture is against either Spain’s Inaki Montes-De La Torre or Czech Hynek Barton in the round of 16, with no further dependency on Galan [1]. The settlement window closing on 27 July 2026 is irrelevant to the outcome, as the match concluded before today’s date. No additional catalysts—such as schedule changes, declarations, or finance disclosures—apply, given the match’s finality and the absence of any cancellation or delay conditions.

FAQ

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Election Predictions UK route into the same order book at 0% fees.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.
