Webull Prediction Markets: How the $0 Commission Model Actually Works
Webull prediction markets route through Kalshi with $0 commission. 3 fee comparisons show what you actually pay vs Robinhood, Kalshi, and DraftKings.
How Webull Prediction Markets Work
Webull prediction markets are event contracts powered by Kalshi's CFTC-regulated exchange. Every trade you place through Webull executes on Kalshi's order book. The contracts, settlement, and regulatory oversight all run through Kalshi. Webull provides the interface, the funding rails, and a $0 commission layer on top.
Webull launched event contracts in Q3 2025 and expanded the offering in January 2026 with $0 commission on sports prediction markets. The model mirrors what Coinbase and Robinhood have done: take an existing CFTC-regulated exchange, wrap it in a familiar brokerage interface, and remove friction for millions of existing account holders.
Each contract trades between $0.01 and $0.99. The price represents the market's implied probability. A contract at $0.40 means the market prices that outcome at 40%. If you think the true probability is higher, you buy Yes. If lower, you buy No. The contract settles at $1.00 if your side wins, $0.00 if it loses. Your maximum loss is what you paid. Run any contract through the PM EV calculator to see whether the math supports the trade.
The $0 Commission Claim: What You Actually Pay
Webull advertises $0 commission on prediction markets. That is technically accurate. Webull does not charge its own commission fee. But you still pay the underlying Kalshi exchange fee on every trade.
The exchange fee is $0.01 per contract per side. Webull adds $0.01 per contract per side as a platform fee. That totals $0.02 per contract on each buy or sell. A round-trip trade (buy and sell, or buy and hold to settlement) costs $0.02 to $0.04 per contract depending on whether you exit early or hold to resolution.
Worked Example: 50 Contracts at $0.45
You buy 50 contracts at $0.45 each. Total cost: $22.50 plus $1.00 in fees (50 x $0.02).
If the contract settles at $1.00, you receive $50.00. Gross profit: $27.50. Subtract $1.00 in buy-side fees. Net profit: $26.50. That is a 117.8% return on your $22.50 investment.
If you sell early at $0.60, you receive $30.00 minus another $1.00 in sell-side fees. Net profit: $30.00 - $22.50 - $1.00 - $1.00 = $5.50. The round-trip fees consumed 27% of your gross profit on that $0.15 price movement.
The pattern is the same as every Kalshi front-end: fees compress thin edges and barely dent large ones. Calculate the exact impact on your specific trade with the fee calculator.
How Webull Fees Compare to Every Other Platform
The fee landscape across US prediction markets has real variation. Here is what each platform charges on a $0.50 contract with a round-trip trade.
| Platform | Commission | Exchange/Platform Fee | Round-Trip Cost (per contract) |
|---|---|---|---|
| Webull | $0.00 | $0.02/side | $0.04 |
| Robinhood | $0.00 | $0.01-$0.02/side | $0.02-$0.04 |
| Kalshi direct (taker) | N/A | ~$0.02/side | ~$0.04 |
| Kalshi direct (maker) | N/A | ~$0.005/side | ~$0.01 |
| DraftKings | $0.00 | $0.02/side (via CME) | $0.04 |
| ForecastEx | $0.00 | $0.01/side | $0.02 |
| Polymarket | N/A | 2% on net profits | Varies |
Three things stand out.
Webull and Robinhood are nearly identical. Both route through Kalshi, both advertise $0 commission, both charge $0.02 per contract per side when you account for the full fee stack. The difference is in execution details, not headline costs. For a deeper comparison, see the Kalshi vs Robinhood breakdown.
Kalshi direct wins for active traders. Maker orders on Kalshi receive a roughly 75% fee discount. If you place limit orders instead of market orders, your round-trip cost drops from $0.04 to approximately $0.01 per contract. Neither Webull nor Robinhood offer maker pricing.
Polymarket uses a completely different model. You pay nothing on losing trades. The 2% only applies to net profits. For traders with many small-edge trades where some lose, this structure can be cheaper overall. Read the full platform comparison for ranked analysis.
The Kalshi Backend: Why It Matters
Every Webull prediction market trade settles on Kalshi's designated contract market (DCM), which is registered with the CFTC. This is not a detail to skim past. It determines three things that affect your bottom line.
Regulatory protection. Kalshi operates under CFTC oversight as a registered DCM. Customer funds are held in segregated accounts. If Webull disappears tomorrow, your positions exist on Kalshi's exchange. This is the same regulatory framework that governs CME futures contracts.
Shared liquidity. You are not trading in a Webull-only pool. Your orders hit Kalshi's full order book alongside traders on Kalshi direct, Coinbase, and other Kalshi-connected platforms. More participants generally means tighter spreads on popular contracts. For thin markets, check the order book depth before committing to a position. The liquidity calculator simulates slippage at different order sizes.
Section 1256 tax treatment. Because Kalshi contracts are CFTC-regulated, they qualify for the 60/40 blended capital gains rate under Section 1256. That means 60% of your profits are taxed at the long-term rate (0-20%) and 40% at your ordinary income rate, regardless of holding period. For someone in the 32% bracket, the effective rate is roughly 25.2% instead of 32%. On $5,000 in annual prediction market profit, that saves approximately $340 in taxes.

What Markets Are Available on Webull
Webull curates a subset of Kalshi's contract catalog. The available categories have expanded since launch but remain more limited than what you find on Kalshi directly.
Index contracts. Hourly and daily S&P 500 price movement contracts. These trade during market hours (8 AM to 4 PM ET). High frequency and high volume.
Crypto contracts. Bitcoin and Ethereum price target contracts. Available 8 AM to 6 PM ET. Hourly resolution means fast feedback loops.
Sports. Game outcomes, championship futures, and player props for major leagues. Webull ran a $0 commission promotion for Super Bowl contracts in January 2026. Sports contracts may be restricted in Maryland, New Jersey, and Nevada.
Economics and politics. Fed rate decisions, inflation ranges, and political outcomes appear on the platform but with a narrower selection than Kalshi's full catalog.
If you need weather contracts, granular economic data strikes (specific CPI numbers, jobs report ranges), or niche event categories, go directly to Kalshi. Webull is designed for mainstream retail appeal, not comprehensive market coverage. For a full list of what each platform offers, see the best prediction market comparison for 2026.
Tax Reporting: What Shows Up and What Doesn't
Tax reporting for Webull prediction markets is the area with the most ambiguity. Here is what is known.
Kalshi issues tax documentation to traders who meet IRS reporting thresholds. This includes 1099-INT for interest earned on cash balances (at or above $10) and 1099-MISC for referral bonuses or credits (at or above $600). For event contract trades specifically, Kalshi does not currently issue a comprehensive 1099-B covering every contract-level acquisition and disposition.
Whether Webull consolidates prediction market activity into its standard brokerage 1099 (the way it does for stocks and options) or relies on Kalshi's reporting has not been publicly clarified as of early 2026. Robinhood, by comparison, includes event contract activity on its consolidated 1099.
The practical takeaway: Track your own cost basis and settlement proceeds for every contract. Do not rely on any platform to reconstruct your full profit and loss. Export your trade history regularly. For a complete tax guide covering all platforms, read how prediction markets are taxed. For Kalshi-specific reporting details, see the Kalshi 1099 guide.
Who Webull Prediction Markets Are Actually For
Webull prediction markets are not the cheapest option, the deepest market, or the most feature-rich platform. They are the lowest-friction option for people who already have a Webull account.
Existing Webull users. If you already trade stocks, options, or crypto on Webull, adding event contracts requires no new account, no separate KYC, and no additional funding step. Time from existing account to first prediction market trade: under 2 minutes. That is the real product.
Casual traders (fewer than 20 trades per month). At low volume, the fee difference between Webull ($0.02/side) and Kalshi maker pricing ($0.005/side) amounts to a few dollars per month. The convenience of a single-platform experience outweighs that cost.
Chart-focused traders. Webull's charting tools and real-time order book data carry over to event contracts. If you use technical indicators on Webull for stocks, the same interface applies to prediction market contracts.
Who should go elsewhere. Active traders placing 50+ trades per month save real money on Kalshi direct with maker pricing. Traders who want the deepest political and macro liquidity should look at Polymarket. Anyone needing full Kalshi market coverage (weather, granular economic data) should trade on Kalshi directly.
