ICE to Acquire MarketAxess for $6 Billion in Cash
Intercontinental Exchange agreed to buy MarketAxess Holdings (MKTX) for $167 a share in cash, a 33% premium, capping a stretch in which the bond-trading platform posted record first-quarter revenue of $233.4 million [1][3][9].
Intercontinental Exchange (ICE) agreed to acquire MarketAxess Holdings (MKTX), the electronic bond-trading platform, for $167 a share in an all-cash deal valuing the company at roughly $6.0 billion in equity and $5.7 billion in enterprise value, or about 10.6 times last-twelve-month EBITDA pro forma for synergies. The offer represents a 33% premium to MarketAxess's July 29, 2026 closing price, and the transaction, financed entirely with new debt, is expected to close in the first half of 2027 pending stockholder and regulatory approval.
The acquisition announcement superseded what would otherwise have been a routine earnings update; the anchor filing carried no standalone quarterly revenue, margin, or EPS disclosure, leaving 1Q26, filed 2026-05-07, as the most recent operating snapshot of the business ICE is buying. That snapshot showed a company still compounding. Total revenue hit a record $233.4 million in the first quarter, up 12% year-over-year and 11% quarter-over-quarter from $209.4 million in 4Q25, with growth outside U.S. credit products running at 20%, powered by record variable transaction revenue in emerging-markets and eurobonds trading, up a combined 21%.
Trading volumes underpinned that revenue trajectory and appear to be accelerating rather than plateauing. Block-trading average daily volume rose 35% year-over-year to a record $6.6 billion in 1Q26, building on 4Q25's 29% increase and full-year 2025's 24% gain to $5 billion. Portfolio trading, the newer and more strategically important channel, grew even faster: average daily volume rose 51% year-over-year to a record $1.9 billion, with U.S. high-yield volumes up 78% and emerging-markets volumes up 69%, outpacing the 41% growth logged in 4Q25.
Margin expansion tracked the volume story closely. Operating margin reached 43.2% in 1Q26, up 690 basis points from 4Q25's 36.3% and 80 basis points from the year-earlier quarter; on an ex-notable-items basis margin reached 44.2%, up 740 basis points sequentially. Total expenses grew 10% year-over-year to $132.5 million, or 8% ex-items, a pace that has consistently trailed or matched revenue growth over the past two quarters and is the mechanical driver of the margin gains.
Diluted EPS told a more mixed story on a headline basis. GAAP EPS of $2.20 fell 12% quarter-over-quarter from $2.51 in 4Q25, though it rose sharply from $0.40 a year earlier against a weak prior-year comparison. Ex-notable-items EPS of $2.25 climbed 34% quarter-over-quarter from $1.68 and 20% year-over-year, a cleaner read on underlying earnings power.
Capital return had been a consistent theme heading into the deal. MarketAxess completed a $300 million accelerated stock repurchase that cut its share count roughly 6% year-over-year as of 1Q26, part of a $505 million buyback authorization announced in December 2025 and reaffirmed in February 2026. Management had also set medium-term targets of 8-9% average annual revenue growth and 75-125 basis points of annual operating margin expansion for 2026 through 2028, a framework that will now be tested against ICE's integration plans rather than MarketAxess's own standalone execution.
For ICE, the purchase price of roughly 10.6 times pro forma EBITDA buys a franchise whose volume growth was still building momentum rather than fading, with both block and portfolio trading setting records in the same quarter. The deal's cash financing and 2027 closing timeline mean MarketAxess will continue reporting as a standalone public company through several more quarters, giving investors a window to judge whether the acceleration in portfolio trading and non-U.S.-credit revenue persists before the business is folded into ICE's fixed-income and data franchise.
