CGT Discount (Australia)

The CGT (Capital Gains Tax) discount is one of the most valuable tax benefits for Australian investors. Individual taxpayers who hold a capital asset for at least 12 months before disposal can exclude 50% of the capital gain from their taxable income.

Application to prediction markets

If the ATO classifies prediction market contracts as CGT assets and you hold a position for more than 12 months, you may be eligible for the 50% discount. However, most prediction market events resolve in days or weeks, making the discount rarely applicable in practice.

Example

You bought prediction market contracts in January 2024 and they settled in March 2025 (14 months). Your gain was AU$8,000. With the 50% CGT discount, only AU$4,000 is added to your taxable income.

Gambling vs. CGT treatment

Australia generally doesn't tax recreational gambling winnings. If prediction markets are classified as gambling rather than financial instruments, profits might be tax-free for hobby traders. However, professional or frequent traders may be assessed on their profits regardless.

How Australia compares internationally

Australia's 50% CGT discount is one of the most generous in the world for long-held assets. By comparison:

• US: Long-term gains (12+ months) get preferential rates of 0%, 15%, or 20% — but no blanket 50% exclusion
• Canada: 50% inclusion rate on all capital gains regardless of holding period — more generous than Australia for short-term trades
• UK: Gambling winnings potentially tax-free entirely
• Germany: Flat 25% rate regardless of holding period

For prediction market traders, Australia's gambling exemption is potentially the most valuable if it applies — turning all profits completely tax-free.

Frequently asked questions

Are prediction markets legal in Australia?

Australian residents can access international prediction markets, though some platforms may restrict Australian sign-ups. The ATO's tax obligations apply regardless of the platform's regulatory status.

Do I need to report prediction market income if I consider it gambling?

If you genuinely classify as a recreational gambler, winnings are generally not assessable and don't need to be reported. However, if the ATO disagrees with your classification, penalties may apply. Seek advice from a registered tax agent if your trading volume is significant.
