Best MLB Prediction Market Apps

Thursday, August 13, 2026 MLB Odds for Key Games

Major League Baseball makes its return to the cornfields of Iowa for a special event broadcast as the Philadelphia Phillies face the Minnesota Twins at 7:30 p.m. ET, streaming on Netflix live from Dyersville, Iowa.

Philadelphia Phillies vs. Minnesota Twins Game Lines

Contract prices fluctuate continuously based on order flow, weather reports, and live pitch-by-pitch activity.

Prediction markets offer prices between $0.01 and $0.99. These help players by directly indicating real-time implied win probabilities. $0.50 means the market thinks there is a 50% chance of something occurring. Contracts then settle at $1.00 if an outcome occurs and $0.00 if it does not.

MLB Field of Dreams Spotlight — Phillies vs. Twins (7:30 p.m. ET, Netflix)

Tonight’s regular-season matchup is our third installment of the beloved MLB Field of Dreams games, played adjacent to the legendary Dyersville, Iowa cornfield made famous by the 1989 Kevin Costner cinematic classic.

Emerging directly out of the cornstalks into a purpose-built 8,000-seat ballpark, Philadelphia (72-47) and Minnesota (64-55) square off in a nationally televised contest streaming exclusively worldwide on Netflix.

Philadelphia sends All-Star left-hander Cristopher Sánchez to the mound against Minnesota right-hander Joe Ryan. The Phillies enter as $0.54 favorites, backed by an offense featuring Bryce Harper, Trea Turner, and Kyle Schwarber.

However, the unique temporary field dimensions, featuring a short 315-foot porch in right-center field and open Iowa prairie winds, create a volatile environment for pitchers.

Expert Pick: Over 9.0 Total Runs ($0.52 / 52% Implied Probability). Historical Field of Dreams matchups have yielded high-scoring matches due to dry Midwestern heat and tight outfield dimensions. Expect Philadelphia's left-handed power bats to exploit the right-field cornfield boundary early, pushing total run contracts past the 9.0 line.
