US election spending expected to reach $16 billion
With just weeks until Election Day, OpenSecrets projects that the 2024 federal election cycle will be the most expensive yet, with spending expected to reach at least $15.9 billion, surpassing the record $15.1 billion from the 2020 cycle.
Outside groups, largely super PACs, have spent roughly $2.6 billion on the 2024 federal elections, outpacing spending in any previous cycle. If the current spending trends hold, OpenSecrets projects that total outside spending for the entire election cycle will exceed $5 billion.Federal election spending for the 2024 cycle is projected to exceed the record set in 2020 — with caveats.
OpenSecrets predicts that 2024’s federal election cycle is on track to be the costliest ever, with a total cost of at least $15.9 billion in spending. But adjusted for inflation, 2024 spending may fall short of the 2020 cycle’s record-breaking total.

This staggering price tag of the 2024 election cycle comes with caveats. Inflation between 2020 and 2024 has been significant. When adjusted for inflation, the 2020 total fundraising total would be the equivalent of $18.3 billion in 2024 dollars.
2020 presidential primaries were significantly more expensive
Former NYC Mayor Michael Bloomberg ran for the Democratic presidential nomination in 2020 and singularly spent $1 billion of his own money on the race during a short 30-day period before dropping out on March 4th, 2020.
In contrast, neither Vice President Kamala Harris nor former President Donald Trump are expected to have spent or raised $1 billion through the end of September.
Combined, Bloomberg and fellow 2020 Democratic presidential candidate Tom Steyer spent over $1.4 billion in their own funds to self-finance their 2020 primary campaigns. Even without factoring in that unprecedented influx of self-funding, Democratic candidates in the 2020 primary still outspent Republican candidates in the 2024 Republican primary by about $500 million.
2024 presidential general election fundraising trends
Fundraising trends are moving in different directions for Harris and Trump. The replacement of President Joe Biden with Harris on the ticket has spurred an enormous boost in fundraising on the Democratic side.
While Harris has not announced September fundraising totals, Harris and the Democratic Party are projected to have raised about $1 billion or more from July through September, based on information provided by the Harris campaign documenting weekend fundraising totals, and what they reported for July and August.
Trump and the Republican Party raised $430 million over the same period, including fundraising totals announced by the campaign and party committee for the month of September as well as what was reported to the FEC in prior months. If fundraising trends continue, this will likely result in Harris exceeding the Biden campaign’s 2020 receipts, while Trump may struggle to match what his campaign reported in 2020.
Going into the final stretch before Election Day, the Harris campaign has not yet reported its fundraising totals from September, but as of the end of August, Harris and the Democratic Party reported $404 million cash on hand. Trump and the Republican Party reported having $283 million at the end of September. Based on previous trends OpenSecrets expects this to be spent before Election Day, in addition to money that will be raised during October, which could easily exceed another $500 million. OpenSecrets analysis of FEC data from 2020 shows the two general election campaigns, along with the RNC and DNC, combined to spend over $1.1 billion between Oct. 1 and Nov. 23.
