Clearing
Clearing is a general term that simply means many different things depending on the subject and related industry. Most commonly, this refers to the reciprocal exchange between banks of checks and drafts, and the settlement of the differences, or the total of claims settled at a clearinghouse.

Read this Term, increased to £46.2 million from £36 million.
The numbers
cover only the UK subsidiary of Nasdaq-listed Interactive Brokers Group, which

At the
group level, the parent company closed the fourth quarter of 2025
with revenue of $1.64 billion and earnings per share of $0.65, beating analyst expectations.
Client Growth Slows From
Prior Year but Stays in Double Digits
The company
said it was the carrying broker for 86,798 clients at year-end, up 35% from
64,146 in 2024. That is a slower pace than the 142% jump recorded the year
before, when client numbers more than doubled from a smaller base.
Net
commissions, which the filing identifies as the company's sole revenue line,
climbed in step with the higher account count.
The growth
follows last year's filing, when the British arm reported a 142% jump in
client accounts and
a more modest 15% revenue increase.
Administrative
expenses rose to £67 million from £59.4 million, while other operating income
reached £10.8 million. The operating line still showed a £9.96 million loss,
though that was narrower than the £16.2 million operating loss recorded in
2024.
The company
relies on finance income, primarily interest earned on client balances and
margin lending, to drive profitability.
Finance
income reached £147.6 million, with £51.5 million coming from bank deposits,
£47.9 million from interest on client balances, and £48.2 million from
intercompany balances.
Of the
interest on client balances, £34.2 million came from margin lending. Finance
costs rose marginally to £103.6 million.
