Boromarket vs Spread Betting UK: Which One Gives You a Real Edge?

Comparing Boromarket prediction markets and UK spread betting — two very different ways to profit from market knowledge, with different risk profiles and tax treatment.

Spread betting and prediction markets are both tools for expressing views on future outcomes without owning the underlying asset. But they work very differently, attract different types of traders, and carry very different risk profiles.

How Spread Betting Works

In spread betting, you bet a fixed amount per point of movement. If you buy the FTSE 100 at £10 per point and it moves 50 points in your favour, you've made £500. If it moves 50 points against you, you've lost £500. There's no upfront premium — just your stake per point and whatever margin your provider requires.

UK spread betting profits are currently free from capital gains tax — a significant structural advantage for active traders.

How Prediction Markets Work

On Boromarket, you buy binary outcome shares. The maximum you can lose is your stake. The maximum you can gain is (£1 minus your entry price) times your shares. Risk is capped on both sides — you can't lose more than you put in, unlike leveraged spread betting.

  • Spread betting: unlimited upside and downside (leveraged)
  • Prediction markets: capped upside and downside (binary, no leverage)
  • Spread betting: continuous price movements
  • Prediction markets: discrete outcomes with clear resolution
  • Spread betting: typically on financial instruments
  • Prediction markets: sports, finance, politics, crypto, entertainment
💡

Prediction markets are better for people who want controlled risk and clear outcome criteria. Spread betting is better for people who want leverage and continuous exposure. They're not the same product.

Which Gives You a Real Edge?

That depends on where your information advantage lies. If your edge is 'I think Arsenal are underpriced to finish top four', a prediction market is the cleaner vehicle. If your edge is 'I think the FTSE will be volatile around the next BoE meeting', spread betting might capture more of the move.

"The best traders don't choose between spread betting and prediction markets. They use each where it fits the opportunity."

Tax Considerations

Tax treatment varies by jurisdiction and individual circumstance. Consult a qualified adviser before making tax assumptions about either product. The boromarket.ai platform has its own documentation on how returns are treated — check the help centre for current guidance.
