Hong Kong Puts Prediction Markets in the Product-Control Box

The Signal

Hong Kong’s Securities and Futures Commission is now treating prediction-market activity as a possible financial-products issue, not only a gambling-law problem. The regulator told the South China Morning Post that certain prediction-market activities may fall within its remit, after at least one international brokerage firm was found operating a prediction-market-style platform in the city.

The local legal debate has shifted from “can Hong Kong ban this?” to “which regulator owns it?” Lawyers told SCMP that prediction markets sit in a grey zone between financial products and illegal gambling, with manipulation, consumer-protection, and enforcement problems that a simple prohibition would not solve.

Hong Kong is becoming the next jurisdiction where platform structure matters. Offshore crypto-native venues, CFTC-regulated U.S. exchanges, and brokerage-distributed event contracts all look similar to retail users, but they create very different licensing, surveillance, custody, and marketing questions for regulators.

The Mechanism

• SFC framing pulls prediction markets toward securities-style oversight. If contracts are treated as financial products, platforms face questions around authorization, client onboarding, risk disclosure, suitability, market conduct, and whether overseas operators are soliciting Hong Kong users.

• Gambling-law treatment would hit distribution first. A ban could restrict local promotion and payment rails, but SCMP’s legal sources warned that enforcement against individuals trading on overseas websites would be difficult, especially when platforms sit outside Hong Kong.

• Brokerage involvement changes the risk profile. A crypto-native website can be framed as offshore gambling or DeFi speculation; an international brokerage offering event-style contracts in Hong Kong invites a cleaner regulatory hook around licensed activity and product classification.

• Polymarket and Kalshi are being used as the global reference set. SCMP cited Polymarket and Kalshi as two of the largest platforms, with reported seven-day trading volumes of $1.1 billion and $2.83 billion, respectively. Hong Kong regulators are not looking at a fringe product anymore.

• Consumer-protection scrutiny is arriving as platform incidents pile up. Polymarket’s recent user-loss estimate rose to $3.1 million after a third-party breach and phishing campaign, according to CoinDesk and TechCrunch. That gives regulators a fresh custody-and-disclosure example alongside manipulation concerns.

• Hong Kong’s decision will matter for Asia distribution. Platforms that want institutional or brokerage access in the region need a pathway that separates regulated event derivatives from illegal wagering. Without one, liquidity stays offshore and retail access moves through VPNs, crypto wallets, and unlicensed intermediaries.

The Landscape

Market Position: Kalshi and Polymarket remain the reference platforms for regulators because they now carry institutional-scale volume and mainstream brand recognition. SCMP cited $2.83 billion in seven-day Kalshi volume and $1.1 billion for Polymarket, while U.S. market structure is broadening through Cboe’s revived S&P 500 binary options and Tradeweb’s dedicated Kalshi data page for institutional clients. The competitive split is sharpening: Kalshi sells regulated U.S. event contracts and institutional workflows; Polymarket sells global liquidity and crypto-native speed, while its U.S. regulated push now has to absorb more trust and security scrutiny.

Regulatory Environment: Hong Kong has not created a bespoke prediction-market regime, leaving platforms exposed to overlapping interpretations under securities, futures, and gambling law. The SFC’s “financial products” language points toward licensing analysis, while local gambling restrictions remain a separate enforcement channel. In the U.S., the CFTC is still fighting state-level attempts to regulate prediction markets, including its lawsuit against Kentucky, while congressional attention on election contracts is raising the political cost of rapid category expansion.

Key Data

• $2.83B: Kalshi seven-day trading volume cited by SCMP via DeFiLlama.

• $1.1B: Polymarket seven-day trading volume cited in the same SCMP report.

• $3.1M: Updated estimate of Polymarket user funds stolen in the recent third-party breach/phishing incident.

• 1+ international brokerage firm: SCMP reported at least one brokerage-linked prediction-market platform operating in Hong Kong, triggering SFC attention.

• 9 states: Number of U.S. states the CFTC has sued to block state-level regulation of prediction-market platforms, according to CBS News.

What’s Next

Hong Kong’s next move is likely to come through product classification rather than a full prediction-market statute. Watch for SFC guidance, enforcement language aimed at brokers, or public warnings on overseas platforms marketing to Hong Kong residents. A financial-products designation would push serious operators toward licensing and disclosure; a gambling-first response would push liquidity further offshore and leave regulated entrants waiting for a clearer path.
