How Regulated Prediction Markets Work in the U.S. — Access, Risk, and What Kalshi Offers

Prediction markets used to live in a gray area — legal fuzz, curious traders, and a lot of news articles asking whether betting on events was really trading. Today it’s clearer: regulated platforms can run event contracts as tradable financial instruments under specific regimes. The result is cleaner access for U.S. users, clearer compliance paths for operators, and new ways for markets to price uncertainty.

Short version: these platforms let people buy and sell contracts whose payoffs depend on real-world events (will inflation be above X in June? will a scheduled policy vote pass?). They look like options or binary contracts in regulated wrappers, with order books, settlement rules, and oversight. The nuance matters — for both users and the folks who build these systems.

Regulated operators—those that cleared the legal and compliance hurdles—offer direct account access through familiar flows: identity verification, funding, placing orders, and settlement. If you want to check a commercial example, see kalshi for a sense of how one regulated venue presents contracts and account workflows.

Why regulation changes everything

Before regulation, many prediction markets resembled informal betting pools. That was fine for academics and hobbyists, but not for institutions or anyone who wanted predictable legal exposure. Regulation transforms event contracts into financial instruments subject to specific rules — custody, anti-money laundering (AML), know-your-customer (KYC), and, crucially, settlement protocols that are auditable.

From a risk perspective, regulation provides guardrails. It doesn’t eliminate market risk — prices still move, liquidity can dry up — but it reduces legal and counterparty risk for end users. For firms, regulation means ongoing costs: compliance teams, audits, and sometimes capital requirements. Those costs show up in spreads, fees, and the set of available contracts.

On one hand, regulated venues attract mainstream traders. On the other, some pure-prediction-market researchers miss the flexibility of experimental platforms. Though actually, the trade-off is expected: you get trust and structure in exchange for fewer contrived contract types.

How account access typically works

Access boils down to three steps: verify identity, fund the account, trade. KYC/AML checks are the gating factor. Expect to provide government ID, proof of address, and sometimes information on source of funds. For U.S. residents, platforms must ensure trades don’t run afoul of gambling or securities laws — a nontrivial compliance maze.

Funding options vary. Some platforms accept bank transfers (ACH), debit cards, or wire transfers. Many platforms hold funds in segregated accounts and provide clear settlement timelines. Withdrawal rules and limits are part of the user agreement; read them. They matter when a fast market movement prompts many users to withdraw at once.

Once cleared, users place orders on event contracts. Contracts are structured with clear settlement outcomes and a settlement oracle or rule. For example, a binary contract might pay $100 if event X occurs and $0 if it doesn’t, with the price quoted between $0 and $100 (or normalized to 0–1). That’s straightforward in concept; the design details (settlement source, dispute resolution window, trading hours) are where things diverge across platforms.

Market structure and liquidity

Regulated prediction exchanges often use limit order books or continuous matching engines. Liquidity can be thin on niche events. That increases slippage and widens spreads. Market makers can help — and on regulated venues they often operate with defined obligations or incentives.

Institutional participation changes dynamics too. When hedge funds or research teams enter prediction markets, they bring capital and modeling that can compress mispricings. That’s a double-edged sword: better pricing for common events, but quicker arbitrage against honest-but-slow traders on niche or long-tail contracts.

One practical bit: check contract tick size and minimum order sizes before you trade. They can materially affect strategy, especially for small accounts.

Regulatory landscape: what U.S. users should watch

Prediction markets in the U.S. operate in a patchwork of authority: federal agencies, state regulators, and sometimes self-regulatory obligations. Commodity Futures Trading Commission (CFTC) oversight can come into play for certain derivatives, while securities law might apply if contracts look like securities. Platforms that market themselves as exchanges typically coordinate with regulators to fit into a permissible category.

Tax treatment is another area to understand. Gains are typically taxable, but the classification (ordinary income vs. capital gains) depends on the contract type and how long you held it. Keep records. Very few platforms provide perfect tax guidance, and you should consult a tax professional rather than rely solely on platform summaries.

Design choices that matter to users

Settlement sources: Is settlement based on a single trusted publisher (e.g., a government release) or a composite feed? Single-source settlement is simpler but concentrates risk; composite or decentralized oracles spread that risk but introduce complexity.

Dispute resolution: Good platforms have a clear, public dispute mechanism and a timeline for resolving ambiguous outcomes. Contracts tied to subjective events (like “will X be considered a success?”) are risky unless dispute rules are tight.

Cooling-off and circuit breakers: For volatile events, look for exchanges with circuit breakers or cooling periods to prevent runaway pricing and protect liquidity providers.

Common user mistakes

Underestimating settlement rules tops the list. People assume “if it looks obvious, it will settle that way” — but ambiguity kills money. Check the contract text for exact trigger definitions and the official settlement source.

Another mistake: ignoring fees. Some venues layer maker/taker fees, regulatory pass-throughs, or spreads that are effectively a fee when liquidity is thin. For small, frequent trades these add up.

Finally, poor record-keeping. If you’re active, export trades and settlements regularly. Taxes and audits are easier when you have a clean ledger.
