Polymarket's accuracy in past elections is generally strong—especially close to resolution and on high-volume national races—but mixed overall, with notable strengths over polls in 2024 and limitations in efficiency, lower-volume markets, and earlier cycles.

Key Metrics for Evaluation

• Accuracy rate: Percentage of markets resolved correctly (e.g., favorite wins).
• Brier score: Proper scoring rule for probabilistic forecasts (lower is better; 0 = perfect, 1 = worst; ~0.25 for random). Sports oddsmakers often land ~0.18–0.22.
• Calibration: How well implied probabilities match real outcomes (e.g., events priced at 70% should happen ~70% of the time).
• Comparison: Vs. polls, models (e.g., FiveThirtyEight, Nate Silver), or other markets.

Polymarket (launched 2020) has limited pre-2024 election history, with explosive growth in 2024 politics ($3+ billion volume on the presidential race alone).

2024 U.S. Presidential Election (Strong Performance)

Polymarket was one of the better forecasters:

• Correctly signaled Trump's victory when many polls/models showed a toss-up or slight Harris edge. Late markets had Trump as a clear favorite (~55-60%+ in final stretches).
• Outperformed national polls in swing states per Bayesian analyses (Vanderbilt study). Implied probabilities tracked closely to final vote shares in key areas.
• Early calls: Predicted Biden withdrawal probability spiking to 70% post-debate (well before announcement). Correctly favored Walz over Shapiro as VP pick.
• Caveats: Large "whale" bets (e.g., one French trader ~$30M+ on Trump) caused swings and potential temporary distortions. Diverged from other markets/polls mid-cycle. One analysis of thousands of 2024 political markets found Polymarket at ~67% accuracy (lower than PredictIt ~93%, Kalshi ~78%), with inefficiencies like arbitrage opportunities.

Overall, a win for the platform and "wisdom of crowds" narrative in a high-liquidity environment.

Broader Track Record (2020s Elections and Markets)

• Political markets: Strongest category. One analysis (thousands of resolved markets): ~81% accuracy on binary electoral outcomes, ~74% multi-candidate, Brier ~0.164. Overall platform Brier often ~0.047–0.187 depending on scope/timeframe.
• Near-event accuracy: ~90% a month out, up to 94% hours before resolution (per Dune dashboard analyses excluding extremes). Politics performs well close to election day.
• Pre-2024/Other cycles: Limited U.S. presidential data (platform young). Mixed results in some international or lower-volume races; markets can lag local info or be overconfident early. Some studies show prediction markets historically competitive with or better than polls but not infallible (e.g., past cycles had misses like over-favoring certain candidates).
• Midterms/Other: Competitive with models; accurate on clear favorites but noisier on close/niche races (e.g., congressional). Lower liquidity leads to more variance.

Strengths

• Financial incentives + crowd aggregation often incorporate info faster than polls (e.g., scandals, turnout signals).
• High volume improves reliability (presidential >> down-ballot).
• Transparent, real-time, and probabilistic.

Weaknesses and Criticisms

• Manipulation/Whales: Large bets can skew prices temporarily (investigated but often not "manipulative" in intent).
• Inefficiencies: Prices diverge across platforms; not always efficient (arbitrage exists); can reflect trader demographics more than electorate.
• Not a crystal ball: Overconfident early; weaker on low-volume or complex outcomes. One view: Good single data point in 2024 but jury still out broadly.
• Bias risks: Crypto-heavy user base may lean certain ways; volume concentration matters.

In summary, Polymarket has built a credible track record, particularly shining in the high-stakes 2024 cycle where it outperformed polls on the presidential outcome. It's a useful signal (especially late and on major races) but best used alongside polls, fundamentals, and other data—not in isolation. For gubernatorial or state races like Kansas 2026, expect solid directional accuracy if volume builds, but watch for liquidity issues. Performance improves as events near.

Sources include academic analyses, Dune dashboards, platform data, and post-election reviews. Accuracy claims can vary by methodology/time window. 

Prediction markets like Polymarket and Kalshi (not traditional sportsbooks with house-set odds) are the main platforms offering bets/markets on the 2026 Kansas gubernatorial race.

These are crowd-sourced—users (traders) buy and sell "shares" in yes/no outcomes (e.g., "Will a Republican win?"), and the market prices (e.g., 70¢ for Yes = ~70% implied probability) emerge from supply/demand. There is no single "odds maker" or bookmaker setting lines centrally. The "wisdom of the crowd" (with money on the line) determines the odds in real time.

Main Platforms for Kansas Governor Markets

• Polymarket: Has active markets on the Kansas governor winner (Republican vs. Democrat) and primaries (e.g., Republican primary winner, with heavy favor for Ty Masterson). High volume on politics.
• Kalshi: Similar markets (e.g., Republican win probability around 70-73% in recent snapshots). CFTC-regulated, fully legal for U.S. users.

Other smaller ones or aggregators exist, but these two dominate visibility for U.S. elections.

Who Runs the Sites?

• Polymarket: Founded in 2020 by Shayne Coplan (CEO, New Yorker, NYU dropout). It's cryptocurrency-based (often on Polygon, USDC), headquartered in NYC. Backed by big investors (e.g., Intercontinental Exchange). Faced CFTC issues early on but has grown massively (billions in volume, especially 2024 elections). Coplan has been outspoken about its accuracy.
• Kalshi: Founded in 2018 by Tarek Mansour (CEO, ex-Goldman/Citadel quant trader) and Luana Lopes Lara (co-founder). CFTC-regulated exchange (first for event contracts). Based in the U.S., focuses on compliance. Valued highly (tens of billions in some reports) with strong growth in elections/sports.

These are tech/fintech startups, not traditional Vegas bookies. They profit from trading fees, not by taking the other side of bets.

Performance and Accuracy Over the Years

Prediction markets have a strong general track record for elections (often better than polls due to financial incentives aligning information), but they're not perfect and can have inefficiencies, manipulation risks, or biases from trader demographics/liquidity.

• Strengths: They aggregate diverse info quickly and have beaten polls in several cycles (e.g., Polymarket outperformed in 2024 presidential, correctly signaling Trump strength when many polls didn't). Studies show high accuracy close to events (e.g., Polymarket ~90-94% in some analyses near resolution; strong on binary outcomes).
• Weaknesses/Limitations: Can diverge across platforms; susceptible to large bets skewing prices (e.g., 2024 Polymarket Trump spikes from big traders); lower accuracy on niche/low-volume markets; historical misses in some cycles (e.g., over- or under-estimating in past U.S. races). One 2024 analysis found varying accuracy (PredictIt high, others lower in some subsets). Not "house odds" but crowd-driven, so liquidity and incentives matter.

For Kansas specifically, markets lean heavily Republican (open seat after term-limited Democrat Laura Kelly, in a red state), but they're dynamic and reflect current sentiment/trading rather than a guaranteed forecast.

Bottom line: No central odds-setters—the crowd does it via these platforms run by Coplan (Polymarket) and Mansour/Lopes Lara (Kalshi). They've been directionally right on many big races recently but treat them as informed probabilities, not certainties (always cross-check with polls, fundamentals, etc.). For the latest Kansas odds, check the sites directly as they fluctuate.

It’s time for Topeka to join Wichita, Derby, Lenexa, Baldwin City, and the growing list of forward-thinking communities. A smart golf cart ordinance is a low-cost, high-impact way to make daily life better while preparing for the future.

Topeka Should Lead Kansas Forward with a Smart Golf Cart OrdinanceTopeka has a real opportunity to position itself as a forward-thinking leader in Kansas by embracing golf carts on city streets. Cities across the state—from Derby and Lenexa to Baldwin City and beyond—have already proven that well-designed ordinances deliver safer neighborhoods, easier mobility, tourism boosts, and a more vibrant, family-friendly lifestyle. With minimal infrastructure investment, Topeka can unlock these benefits while supporting local developments, retirees, and events.Kansas State Framework Makes It PossibleUnder Kansas law (K.S.A. 8-15,108), golf carts are generally prohibited on public streets unless a city passes its own authorizing ordinance. The statewide baseline is straightforward:

• Operation limited to daylight hours (sunrise to sunset)
• Banned on interstates, federal, or state highways
• Must include at least one rearview mirror and one side mirror
• Operators generally need a valid driver’s license (age 16+ in most local programs)
• Cities control the details: allowable road speeds (typically 25–30 mph), required equipment, registration, insurance, and restricted zones

Low-Speed Vehicles (LSVs) offer another pathway—they’re titled and registered more like cars and can access more roads—but a targeted golf cart ordinance gives cities the most flexibility for neighborhood-focused use.What’s Working in Kansas CitiesSeveral Kansas communities have successfully rolled out golf cart programs with strong resident support and few issues:

In Wichita, you can drive a golf cart on city streets where the speed limit is 30 mph or less. Operators must be at least 16, hold a valid driver's license, and carry liability insurance. Carts are illegal on major highways, must be equipped with specific safety features, and are not allowed on sidewalks or bike lanes. [1, 2, 3]

The City of Wichita strictly enforces the following regulations for street-legal golf cart operation: [1]

• Street Limits: You can only use carts on public streets with a posted speed limit of 30 mph or less. Carts are strictly prohibited on state, federal, or interstate highways. [1]
• Intersections: Golf carts can cross roadways with speed limits exceeding 30 mph, but only at controlled intersections. [1]
• Required Equipment: To be street-legal, carts must be equipped with functional brakes, brake lights, tail lights, rear reflectors, and at least one rearview mirror. [1]
• Nighttime Driving: Carts are generally prohibited on streets from 30 minutes before sunset to 30 minutes after sunrise unless they are equipped with motorcycle-equivalent lights and a slow-moving vehicle emblem. [1]
• Driver & Insurance Requirements: Drivers must be 16 years or older with a valid Class C driver's license, and you must carry liability insurance on the cart. [1]
• Passenger Rules: Occupants are strictly limited to the number of factory-installed seats. Passengers cannot sit on the driver's lap or ride anywhere not designated for seating. [1]
• Sidewalk & Path Ban: While golf carts can be legally driven on sidewalks and multiuse paths in some cities, Wichita explicitly prohibits driving golf carts on city sidewalks, jogging paths, or bike lanes. [1, 2]

You can view the full municipal details directly on the Wichita Operation of Golf Carts Ordinance portal.

• Derby (near Wichita, ~25,000 population): Updated its ordinance in 2023. Golf carts are allowed on streets posted at 30 mph or less (with careful crossing of higher-speed roads). Requirements include a driver’s license, liability insurance, annual $25 registration with a police decal, and proper safety equipment. The city provides clear maps and FAQs. Residents love the convenience in neighborhoods, and the program has operated smoothly with an emphasis on shared-road responsibility.  
• Lenexa (Johnson County, suburban Kansas City): Permits carts on roads with 25 mph limits or less. Mandates headlights, taillights, brake lights, insurance, and adherence to all traffic laws (including DUI rules). Occupants are limited to factory seating. The program enhances local travel while keeping pedestrians safe.
• Baldwin City: Allows golf carts and UTVs on city streets with standard equipment rules, a driver’s license, and proof of liability insurance. It integrates well with community life near the golf course and maintains clear distinctions from banned vehicles like ATVs.

Other successful examples include Scott City, Garnett, De Soto, Andover, Augusta, Spring Hill, Olathe, Shawnee, Eureka, and South Hutchinson. The pattern is consistent: focus on low-speed streets, safety equipment, licensed drivers, and clear boundaries. Smaller towns use carts for practicality; suburban areas use them for lifestyle appeal.Wichita has been more cautious, but the track record in peer cities shows these concerns are manageable with thoughtful rules.The Clear Benefits for Topeka

• Enhanced Mobility & Lifestyle: Short trips to parks, shops, events, or neighbors become easier and more enjoyable. Perfect for 55+ developments, pickleball communities, and mixed-use projects.
• Tourism & Economic Lift: Carts create a fun, walkable vibe that supports local businesses and events—much like they do in resort towns.
• Low Cost, High Return: No major road overhauls needed. Registration fees can generate revenue, and electric carts align with sustainability goals.
• Positive Community Response: In Derby, Lenexa, and similar cities, residents appreciate the freedom when rules are clear and enforced.

Addressing Concerns Head-OnEvery new idea has challenges, but Kansas cities have shown how to handle them effectively:

• Safety: Limit use to low-speed streets, require lights, emblems, flags, and horns, and enforce daylight-only rules (or add lighting for exceptions). Education campaigns and yield-to-traffic requirements keep incidents low.
• Enforcement: Require insurance, annual registration with visible decals, and full compliance with traffic laws. Police can easily verify compliance.
• Traffic & Parking: Use detailed maps, no-parking zones, and crossing protocols (as Derby does).
• Opposition: Data from successful peer cities, public input, and a possible pilot phase help build consensus.

When ordinances are detailed, safety-focused, and geographically targeted, problems remain rare.Recommendations for a Successful Topeka OrdinanceTopeka can create a program tailored to its needs:

1. Start Conservative: Allow carts on streets posted 25–30 mph or less, daylight hours only, and in defined zones (neighborhoods, parks, downtown edges, new developments). Publish an official map.
2. Core Requirements: Valid driver’s license (16+), proof of liability insurance, annual registration fee ($20–50), slow-moving vehicle emblem, lights, horn, mirrors, and seatbelts where feasible. All standard traffic laws apply.
3. Build Support: Offer safety education, incentives for electric carts, and tie the program to economic development and quality-of-life initiatives.
4. Implementation Path: City staff drafts the ordinance, holds public hearings highlighting peer successes, and considers a pilot phase. Monitor results and adjust as needed.

Topeka has everything to gain: more convenient neighborhoods, stronger tourism and events, appeal to retirees and families, and a reputation as a progressive Kansas city that gets things done.
It’s time for Topeka to join Derby, Lenexa, Baldwin City, and the growing list of forward-thinking communities. A smart golf cart ordinance is a low-cost, high-impact way to make daily life better while preparing for the future.

Derby, Kansas Golf Cart Ordinance (Updated April 2023)Derby’s current golf cart rules are codified primarily in Section 10.04.114.4 of the Derby Municipal Code (Traffic Ordinance). The City Council approved updates on April 25, 2023, expanding citywide access on qualifying streets while maintaining strong safety and registration requirements. The ordinance took effect in early May 2023.Key Definition of a Golf CartA golf cart is defined as a motor vehicle that:

• Has not fewer than three wheels in contact with the ground.
• Has an unladen weight of not more than 1,800 pounds.
• Is designed to be (and is) operated at not more than 25 mph.
• Is designed to carry not more than four persons, including the driver.

Core Operational Rules (10.04.114.4)It is unlawful to operate a golf cart on any street or roadway in Derby unless all three conditions are met:

1. The posted speed limit is 30 mph or less.
2. The operator has a valid driver’s license.
3. The golf cart is registered as a special purpose vehicle with the Derby Police Department, displays a valid registration decal, and is insured per city code (Section 10.04.114.6).

Prohibited Operations (even if the above are satisfied):

• On any state, federal, or interstate highway within city limits.
• On sidewalks, jogging paths, trails, or any pedestrian areas (unless specifically designated as a golf cart path).
• On private property without owner permission.
• Between sunset and sunrise unless equipped with headlights (as required for motorcycles by state law) and a properly mounted slow-moving vehicle emblem (per K.S.A. 8-1717).
• In a manner where the golf cart suddenly leaves a path or safe place and enters the path of a vehicle so close as to create an immediate hazard (golf carts must yield to traffic).
• With more occupants than factory-installed seats.

Crossing Higher-Speed Streets:

• Golf carts may cross streets posted at less than 40 mph at any intersection.
• For streets posted at 40 mph or greater, they must cross at a signalized intersection.
• A city map illustrates allowed streets and crossing points.

Exceptions: These rules do not apply to golf carts used for authorized governmental duties.Penalties: Violation is punishable by a fine of up to $1,000, imprisonment up to 6 months, or both.Registration Requirements

• Annual registration with the Derby Police Department (fee: $25 per calendar year, non-prorated; renews each January).
• Submit application form, proof of liability insurance, and vehicle details.
• Receive a decal to display clearly on the rear of the cart.
• Police may inspect for compliance (brakes, lights, mirrors, slow-moving emblem, etc.).

All standard Kansas traffic laws apply, including DUI and open container rules.Context and Intent of the 2023 UpdatePrior to 2023, use was more restricted (often limited to specific neighborhoods or direct routes to amenities/golf courses). The update expanded access citywide on 30 mph-or-less streets for broader resident convenience, while adding clearer crossing rules, occupant limits, and pedestrian protections. City staff noted it aligns Derby with more permissive peers like Andover and Olathe, improves enforceability, and reflects actual community use.Practical Summary from City Resources

• Licensed drivers only (no children operating on streets).
• Daylight preferred; proper lighting + emblem required at night.
• Yield to traffic when crossing.
• Registration is straightforward via police department drop-off.

Derby’s approach balances lifestyle benefits with safety through speed/equipment/registration limits and geographic mapping.
