DraftKings Predictions (DKeX), Reviewed

First, the methodology note, because it is the whole point: EventMarkets is independent. We take zero compensation from platforms we cover, run no affiliate links, and there is no promo code at the bottom of this page. DraftKings did not see this review before publication and cannot buy a better score — which matters, because most of what ranks for “DraftKings Predictions review” is written by affiliates with a signup link to protect.

Now the answer. DraftKings Predictions is a real, federally regulated prediction market — since June 2026 it runs on DKeX, an exchange DraftKings owns outright — and it is the easiest way for a sports fan in California or Texas to trade an event contract. It is also, as of August 2026, a thin one: fees that undercut a sportsbook but not Kalshi, no order book or limit orders, and sports contracts tradable in just 18 states. This review scores what a trader actually gets.

What is DKeX, and how did DraftKings get here?

DKeX is the DraftKings Exchange — legally Railbird Exchange, LLC, a startup that won CFTC designation as a designated contract market in June 2025 and that DraftKings acquired on October 21, 2025 — the same category of federal license Kalshi holds.

The product came before the exchange. DraftKings Predictions launched December 19, 2025 in 38 states on rented rails, routing trades to CME Group; parlay-style “combos” arrived in May 2026 via Crypto.com’s derivatives exchange. Then on June 26, 2026, DraftKings launched DKeX, folded Predictions into its main Sports & Casino app, and in July won approval to operate as a futures commission merchant — exchange, clearing relationship, and brokerage all in-house. The cutover is gradual: the fee disclosure still lists CME and Crypto.com (CDNA) markets alongside DKeX ones. On August 10 it self-certified nine football contract categories plus combos for DKeX, effective August 11 — sides, totals, props, and season awards, in place for the season.

Where can you actually use it?

The defining question — and the answer is a four-tier map. Per DraftKings’ own availability page, as of August 18, 2026:

Tier	Jurisdictions
All markets, including sports (18 states)	AL, AK, CA, DE, FL, GA, HI, ID, MN, NE, NM, ND, OK, RI, SC, SD, TX, UT
Everything except sports (19)	CO, DC, IN, KS, KY, MD, MA, MS, MO, NJ, NY, NC, OR, PR, VT, VA, WV, WI, WY
Financial markets only (13 states)	AZ, AR, CT, IL, IA, LA, MI, MT, NV, OH, PA, TN, WA
Nothing (2 states)	ME, NH

DraftKings Predictions market availability, per DraftKings, as of August 18, 2026. Minimum age 18; not available on tribal land.

Read the tiers together and the logic jumps out: not one of the 18 all-markets states is a state where DraftKings Sportsbook takes online bets — the roughly 27 states (plus DC) with a DraftKings sportsbook all sit in the lower tiers. Sports contracts reach the giant unserved states, California and Texas above all, while DraftKings avoids a competing, state-untaxed sports product anywhere it holds a license a regulator could threaten. The financial-only tier tracks the states that have moved hardest against sports contracts — Nevada, Arizona, Illinois, Ohio, and Tennessee among them; in November 2025 DraftKings even withdrew its pending Nevada sportsbook license applications rather than fight that regulator.

The sportsbook and the exchange never operate in the same state. The map is the strategy.

Kalshi lists sports contracts in all 50 states and litigates every challenge; DraftKings geofences first — so your access depends on your state’s tier, and tiers can change.

What do the fees actually cost you?

DraftKings charges a flat per-contract fee on every buy and every sell, banded by price, per its current schedule (as of August 2026); there are no settlement or withdrawal fees. Simple — but set it against Kalshi’s formula-based taker fee, remembering Kalshi charges makers nothing in most markets:

Contract price	DraftKings fee (per side)	As % of stake	Kalshi taker	Kalshi maker
10¢	1¢	10.0%	0.63¢	0¢
50¢	2¢	4.0%	1.75¢	0¢
90¢	2¢	2.2%	0.63¢	0¢

Per-contract, per-side fees from each platform’s published schedule, as of August 2026. DraftKings’ bands: 1¢ at 1–19¢ and 97–99¢, 2¢ at 20–96¢, inclusive of all broker and exchange fees; CME-routed markets are a flat 2¢. Kalshi’s maker rate is zero in standard markets.

Worked example: buy 100 YES at 60¢. Stake $60, fee $2. Hold to a win and you collect $100 — $38 profit after the fee; exit early instead and you pay another $2 on the way out. The flat structure punishes longshots hardest: $100 put into 10¢ contracts buys 1,000 of them and costs $10 in fees — 10% of the stake gone at entry, where the same trade costs a Kalshi taker $6.30 and a patient Kalshi maker nothing. On DraftKings, patience buys nothing: the app takes market orders only — no limit orders, no visible order book, no depth data (as of August 2026, corroborated by independent testing) — so every fill pays whatever spread the market makers are showing, a cost you can’t see and the fee table doesn’t capture.

How is this different from the DraftKings sportsbook?

Structurally, completely — and the differences mostly favor the trader. A sportsbook sets the line, books your bet against the house, bakes roughly a 4.5% hold into a standard -110/-110 market, and locks you in until settlement. An exchange matches you against other participants at a price that maps directly to a probability, charges a disclosed fee instead of a hidden margin, and lets you exit before settlement at the market’s current price — the single biggest practical advantage over the sportsbook next door in the same app. One oddity: prices display as moneylines by default — exchange mechanics dressed in sportsbook clothes.

Then there are combos: up to six contracts bundled into one position priced as a single instrument, every leg required to settle YES for it to pay $1, with the per-contract fee applied to each leg. The company says more than 30% of customers have used the feature. Understand what stacking does to the math: probabilities multiply down while fees add up, so a six-leg combo is a long-odds instrument paying six separate fees — the parlay’s expected-value profile, rebuilt in contract form. We describe it; we don’t recommend it.

Is there real liquidity, and who settles disputes?

The volume is growing fast from a small base: annualized total volume went from $2.3 billion in April to an $11 billion run rate in July 2026, per DraftKings’ earnings call. Two caveats. Scale: Kalshi did roughly $29 billion in the single month of June, per Sacra’s estimates — DraftKings’ annualized figure is a fraction of Kalshi’s monthly one. Composition: at the DKeX launch DraftKings cited $11.3 billion annualized total volume but only $3.4 billion of it as consumer volume — roughly 70% of the flow coming from market makers and institutions rather than customers. And with no order book displayed, you find out what liquidity exists when your market order fills.

On resolution: DKeX contracts settle per written payout criteria under the exchange rulebook, which includes an unusually formal arbitration process — filing forms, discovery procedures, scaled fees — genuinely more built-out than Kalshi’s. That is worth something. But the track record is eight months old, no Khamenei-scale controversy has tested it, and DraftKings is operator, broker, and — per allegations below — sometimes a liquidity provider in its own markets. Unproven isn’t bad; it’s just unproven.

What’s the legal risk?

The category fight covers every sports-contract platform: states argue sports event contracts are unlicensed gambling; platforms argue they are swaps under exclusive CFTC jurisdiction; federal courts have mostly, not uniformly, sided with the platforms. Our 50-state legality tracker follows that war ruling by ruling, including New York’s suit against Kalshi.

DraftKings now has a case with its own name on it. On July 28, 2026, a proposed class action — Chan v. DraftKings Inc. and GUS III LLC, No. 1:26-cv-13442, District of Massachusetts — alleged that Predictions is an unlicensed sportsbook in eight states where DraftKings holds no betting license, California and Texas included. The complaint leans on DraftKings’ own investor statements — quoting the CEO saying “customers don’t really even understand the difference” between the two products — and alleges DraftKings takes the other side of thin markets itself. These are allegations: DraftKings had not responded as of mid-August 2026, no class is certified, and similar suits face strong federal-preemption defenses. But the company that built a licensed sportsbook first is the natural target for the argument that the label is the only difference.

The honest cons

• Sports in 18 states only. The flagship catalog is unavailable to most of the country, including every DraftKings Sportsbook state — and the map can shrink as easily as it grows.
• No trader tools. Market orders only: no limit orders, no order book, no depth or price history. You take the spread you’re given and can’t measure it first.
• Fees beat the sportsbook, not the competition. Costlier than Kalshi at every price point — dramatically so for longshots — with no maker path to trade free.
• Thin catalog. Overwhelmingly sports plus a short shelf of stock-index and crypto price markets; politics and entertainment are sparse.
• Untested resolution, unresolved litigation. Eight months of history, a conflicted operator role, and a direct class action amid the category-wide regulatory contest.

Verdict: 6/10

DraftKings Predictions is the most polished on-ramp in prediction markets: genuinely regulated end to end, trivially easy for a sports fan in a no-sportsbook state, with early exit and probability pricing quietly improving on the products it resembles. It is not yet a serious venue for traders — the fees, the missing order book and limit orders, and the 18-state sports map keep it a full tier below Kalshi’s 7.5. As of August 2026, it’s a strong second-tier platform whose ceiling depends on how much exchange DraftKings actually lets DKeX become.

Quick answers

Is DraftKings Predictions legit? Yes. Trades execute on CFTC-regulated exchanges — primarily DKeX, DraftKings’ own designated contract market — through a CFTC-registered brokerage, and contracts settle at $1 or $0. The open legal questions are about which regulator governs sports contracts, not whether it pays out.

What is DKeX? DraftKings’ proprietary exchange, built from Railbird Exchange, a CFTC-designated contract market acquired in October 2025. It launched June 26, 2026, replacing rented rails from CME Group and Crypto.com, though some markets still route to those exchanges.

Which states have DraftKings Predictions? As of August 18, 2026: the full catalog including sports in 18 states (California, Texas, Florida, and Georgia among them); everything except sports in 19 jurisdictions; financial markets only in 13 states; nothing in Maine or New Hampshire. Sports contracts are unavailable in every DraftKings Sportsbook state.

What does trading cost? A per-contract fee on each buy or sell: 1¢ for contracts priced 1–19¢ or 97–99¢, 2¢ from 20¢ to 96¢ (CME-routed markets: flat 2¢ per side). No settlement, deposit, or withdrawal fees; the minimum deposit is $5. There are no maker discounts and no limit orders, so every trade also pays the market makers’ spread.

Can I lose more than I put in? No. Maximum loss is what you paid; there is no leverage or margin. Single-market positions can be sold before settlement at the current market price.

How are winnings taxed? DraftKings says event-contract payouts may be reported as income on Form 1099. How event contracts are ultimately classified remains unsettled — see our prediction market taxes guide and ask a professional.
