Dallas Hit 101°F on July 9, Market Resolved at 100-101°F | Lines.com

Dallas recorded a high of 101 degrees Fahrenheit on July 9, 2026, landing the outcome squarely in the 100-101°F resolution bracket. Multiple weather stations across the Dallas metro, including Dallas Love Field, confirmed the 101°F peak before the noon resolution window closed. The market resolved at full value on July 9, 2026.

Traders had the right read. The market opened at 28 cents for the 100-101°F bracket and surged to 100 cents by resolution, a 72-point move driven heavily by real-time temperature data on July 9. The $55,678 in total volume signals meaningful conviction, even for a same-day temperature market. The implied probability at open was 28%; the final price at close was 100%. The market finished as a clean underpriced YES.

Dallas Reached 101°F, Confirming the 100-101°F Bracket

The Dallas high of 101°F on July 9 fell within the 100-101°F range, which was one of ten outcome brackets this market offered. Weather Underground reported the forecast high at 101°F by early afternoon on July 9. AccuWeather’s monthly data for Dallas corroborates that figure, logging July 9 as a 101°F day. The resolution window closed at noon local time, and the measurement met the threshold before that cutoff.

The final price at close hit 1.00, meaning traders who held the 100-101°F position through settlement collected full value. The 24-hour price movement on July 9 tells the story: three separate upward surges of 5%, 18%, and 14% compressed into a single trading day as real-time temperature readings came in above 95°F and kept climbing.

How the Market Performed on the 100-101°F Bracket

The 100-101°F bracket opened at an implied probability of 28%. That is a meaningful underpricing for a bracket that ultimately resolved YES. The final close at 100% confirms the market started the day skeptical about exactly this temperature range, despite Dallas averaging a July high of 98°F. The market is pricing uncertainty, not science. Early traders underweighted the probability that a typical Dallas July day would land in the most climatologically probable range.

Total volume of $55,678 with $12,062 traded in the final 24 hours shows that late-session activity drove the convergence. The $36,367 in liquidity supported clean price discovery as the temperature data updated in real time. For a granular meteorological market with ten possible brackets, that volume reflects genuine trader engagement rather than thin noise.

• Resolution Outcome: 100-101°F bracket confirmed YES on July 9, 2026.
• Article-Time Probability: 28% implied probability at market open.
• Final Price at Close: 1.00 (100%).
• Total Volume: $55,678.
• Market Assessment: Underpriced YES. The market opened well below fair value for the most climatologically likely bracket.

What a 101°F Day in Dallas Means Going Forward

Dallas is in the heart of its peak heat season. July averages a high of 98°F at Dallas Love Field, and the city has logged an increasing number of 100-degree days in recent years according to NOAA’s National Weather Service Fort Worth/Dallas climate records. A 101°F reading on July 9 is above average but far from exceptional for the metro. The broader North Texas heat pattern for mid-July 2026 shows continued above-average temperatures forecast through the third week of the month.

Here’s what the measurements are telling us about this market structure: ten-bracket temperature markets create a deceptively wide distribution. No single bracket carries obvious majority probability on any given day, which makes early pricing inherently uncertain. The market corrected aggressively once intraday observations confirmed the temperature trajectory, which is exactly how meteorological markets should behave. The binary structure per bracket worked well here because the measurement source was unambiguous and the resolution window was clearly defined.

• Dallas temperatures are forecast to remain at or above 99°F through mid-July 2026, keeping heat-related market activity elevated across similar prediction contracts.
• The 100-101°F bracket was the single most climatologically probable outcome given Dallas July historical averages, yet the market opened it at just 28 cents, highlighting a systematic underweighting of the modal outcome in multi-bracket temperature markets.
• NOAA’s Fort Worth/Dallas office tracks 100-degree day accumulations annually for the DFW metro; 2026 is pacing above the 30-year average for July heat days.
• Future Dallas temperature markets will likely see faster early convergence to the modal bracket as traders calibrate to the July climatology and same-day weather station data feeds.

LINES RESOLUTION VERDICT

UNDERPRICED YES

The 100-101°F bracket was the most climatologically grounded outcome for a Dallas July day, yet the market opened it at 28 cents and only corrected when real-time temperature data made the result unavoidable.

What the market showed: The implied probability started at 28% at open versus a final close of 100% and a confirmed 101°F outcome. The market underpriced the modal July temperature bracket by a wide margin, correcting in three sharp intraday moves as Dallas climbed through the 90s and into triple digits.
