How Delaware taxes prediction market profits
Delaware taxes event contract profits as ordinary income at state rates up to 6.6%.
At the federal level, platforms like Kalshi issue annual 1099-MISC forms reporting net profits as ordinary income. You can deduct up to $3,000 in net losses per year against other income, carrying forward the remainder to future years. If you trade sports event contracts, the One Big Beautiful Bill Act (OBBBA, signed July 4 2025) caps sports betting loss deductibility at 90% starting in 2026.
