Preliminary results for Wall Street's competitive league table rankings are in — and it's looking good for JPMorgan.

Races in other lines of business — like equity capital markets — are too close to call.

The year in dealmaking is closing with a bang, with late-arriving megadeals shaking up some of the rankings of Wall Street's top investment banks.

With just under two weeks to go before close of the 2017, Dealogic is out with its preliminary results for the year in investment banking — and it's looking like another big year for JPMorgan.

Some league-table races are all but over: With $6.4 billion, JPMorgan has a healthy lead in overall investment banking revenues. Second-place Goldman Sachs trails by $820 million.

But some lines of business will come right down to the wire: In global ECM by revenue, Morgan Stanley leads JPMorgan by just $4 million — $1.27 billion to $1.266 billion.

Across the industry, revenues increased to a three-year high of $78.1 billion, led by the revival in global equity capital markets, which saw a 25% increase in annual revenue to $17.6 billion.

A wave of announced mega-transactions have made the fourth quarter the sixth-busiest quarter for mergers and acquisitions in the past decade, according to Dealogic. The four-largest tie-ups of the year were all announced in Q4, including Broadcom-Qualcomm ($130 billion), CVS-Aetna ($69 billion), Disney-21st Century Fox ($69 billion), and Hochtief-Abertis Infraestructuras ($42 billion).

Still, it's a down year overall for global M&A, falling 9% to $3.52 trillion.

Here's a breakdown of the preliminary results for the major rankings, according to Dealogic. Read on to see who's on pace to win bragging rights this year:

JPMorgan is set to retain its crown as the top overall investment bank. In general, there was very little movement from the overall revenue rankings from 2016.

Goldman Sachs appears a shoe-in to retain bragging rights for revenue from global M&A. The firm had a leading role on the three largest deals of the year — Broadcom-Qualcomm ($130 billion), CVS-Aetna ($69 billion), Disney-21st Century Fox ($69 billion).

Goldman Sachs also leads global M&A by volume. But the story here is boutiques: Evercore climbs to 8th from 11th, and Centerview Partners — a firm of just 37 senior bankers — jumped to 7th from 12th after landing assignments on both December megadeals: CVS-Aetna and Disney-21st Century Fox.

JPMorgan leads in revenue from global debt capital markets. It was a record year for high-yield bonds with $498 billion issued, up 46% from 2016.

Citi jumped JPMorgan for first place in global DCM by volume, with $483 billion in deals. The $6.74 trillion in overall global DCM volume ties 2016 for the largest year on record.

Global equity capital markets revenue is too close to call. Morgan Stanley leads JPMorgan by just $4 million, and by market share they're tied at 7.2%. Goldman Sachs is lurking not far behind in third. This race could still flip before the end of the year.

Global ECM by volume rebounded after an icy cold 2016, climbing 16% to $843 billion. This race is also close, but Goldman Sachs leads Morgan Stanley by market share — 7.8% to 7.7%. JPMorgan has dropped from first to third.
