Deposit-match bonuses add a percentage of your deposit as credit, often up to a cap. The credit works as extra margin rather than cash, and a turnover requirement decides whether any of it becomes withdrawable.
XM
XM matches your deposit 100% on the first $500 and 20% after that, up to $10,500 in bonus credit you can trade with but cannot withdraw directly.
FBS
FBS matches your first deposit 100% up to $10,000 and adds up to 60% on later deposits, but the bonus credit itself is non-withdrawable and only boosts your trading margin.
HFM
HFM matches each qualifying deposit 100% up to $50,000 in non-withdrawable trading credit and pays daily cash rebates of about $2 per Gold lot (capped at $8,000), available to non-EU traders on Premium and Islamic accounts.
HFM
HFM credits a percentage bonus (10% up to 100% depending on the regional campaign, capped around 5,000 USD) on every deposit into a Top-Up Bonus account, with profits withdrawable but the bonus credit locked as trading margin.
Tickmill
Tickmill matches your deposit by up to 20% to a maximum of $1,000, but you must trade one standard lot per $3 of bonus before the bonus credit can be withdrawn.
IC Markets
IC Markets matches your first deposit 100% and every later deposit 50%, up to $25,000 in non-withdrawable bonus credit that boosts your trading margin while any profits stay yours to keep.
InstaForex
55% credit on every deposit. Profits are freely withdrawable; the bonus itself only after an extremely high turnover.
Moomoo
Moomoo US gives a 3% Cash Coupon match (up to $600) on your first ACAT transfer of $1 to $20,000, paid in four quarterly installments and usable only to buy US stocks and ETFs in-app.
