What is Chalkboard?

Chalkboard is a pick'em app (check availability in the app) that lets users take positions on the outcomes of real-world events — sports, politics, economics, and culture. Founded in 2021, it operates under U.S. federal commodities law and is available in most US states; availability depends on your state.

What sets Chalkboard apart is its positioning: player props, simplified.. That's not marketing copy — it's reflected in the product, the markets offered, and the kind of trader who sticks around.

Is Chalkboard legal in the US?

Chalkboard is a player-prop pick'em app, not one of the CFTC-regulated exchanges we track; availability depends on your state, so check in the app. Whether states can regulate sports event contracts is contested: at the preliminary-injunction stage the Third Circuit sided with Kalshi (April 6, 2026), while the Ninth (August 28, 2026) and Sixth (September 25, 2026) Circuits ruled Kalshi is unlikely to show federal law blocks state gambling laws. Three Supreme Court petitions are filed; none granted yet. What you can trade can change by state.

That said, the legal picture is still being contested. Some state attorneys general have challenged certain platforms; the CFTC has consistently defended its jurisdiction. For the full backdrop, see our US legality guide.

What can you trade on Chalkboard?

Chalkboard covers Sports, Player Props, NBA, NFL. New markets are added weekly.

Practically, that means contracts on game outcomes, championship futures, player and team milestones, election results, Fed decisions, inflation prints, award shows, and cultural events.

How does Chalkboard work?

Every contract on Chalkboard resolves to either $1 (yes) or $0 (no). The price you pay reflects the market's implied probability — a contract at 62¢ means a 62% chance.

You don't have to hold to resolution. You can sell at any time — if the price moves to 78¢, you can lock in the gain. This is the single biggest mental shift from sportsbook betting: you're trading a price, not placing a wager. For the full mechanic, read how event contracts work.

How much does Chalkboard charge?

Chalkboard charges fees on a per-contract basis, typically a small fraction of a cent per contract or a low percentage of the trade. Compared to a sportsbook's 5-10% built-in vig, the fee structure is dramatically more transparent.

Liquidity varies by market — high-profile events like presidential elections or playoff series are deep, while niche markets can be thin. Always check the bid-ask spread before taking a position.

Is Chalkboard safe?

Yes. Chalkboard is regulated by the CFTC, segregates customer funds, and is required to meet federal compliance and reporting standards.

That regulatory backstop is the single biggest reason US traders choose federally-regulated venues over offshore sportsbooks, which operate outside U.S. consumer protection.

Who should use Chalkboard?

Chalkboard is best for player props, casual sports fans, and mobile trading.

If that profile fits you, Chalkboard earns its 4.0/5 rating and belongs in your account rotation.

Who should not use Chalkboard?

Chalkboard is not ideal for world cup futures traders or politics and macro.

If that's you, browse our full platform rankings for a better fit.
