The upcoming midterm elections will be the most expensive elections ever conducted in the US.

elections → conduct → US
And more of the money is “dark” than ever before, meaning it’s impossible to get a full picture of who is spending gargantuan sums to influence races that could provide a critical check on Donald Trump’s second term.
uncertain
that → mean → term
The elections have also shown how money in politics is being reshaped, with the increasingly powerful role played by big donors from the tech industry as well as the growing concentration of spending among a few powerful individuals and corporations.
asserted
money → show → individuals
The impact of the rise of megadonors such as Tesla founder Elon Musk, and an increase in dark money among the very top donors, on this year’s electoral outcome is hard to quantify.
asserted
impact → quantify → outcome
Ad industry tracker AdImpact predicts $11.6bn in ad spending this cycle, surpassing the $11.2bn spent in the 2024 presidential election.
asserted
AdImpact → predict → election
OpenSecrets, a nonpartisan research group tracking money in politics, pegs total spending in the midterms as on track to reach $11.9bn.
asserted
OpenSecrets → track → 11.9bn
The top 40 donors are giving more than ever before: $2.4bn by mid-October, seven times the amount the top 40 in 2014 gave, adjusted for inflation, according to a new analysis from the nonpartisan, pro-campaign finance reform institute the Brennan Center for Justice.
uncertain
40 → give → Justice
But the significant difference since then is that those top donors now give more to Republicans, and by a larger differential.
asserted
donors → give → differential
In 2014, the top 40 gave to Democrats two to one, but this year the top 40 gave to Republicans three to one over Democrats.
asserted
40 → give → Democrats
Spending from Super Pacs, which can accept unlimited amounts of money to spend in elections, hit the $2bn mark by the end of September, which is 51% higher than the last midterm cycle, adjusted for inflation, according to the Brennan Center analysis.
uncertain
which → accept → analysis
And the New York Times counted at least $1bn that has already been spent by dark money groups by the end of August.
asserted
that → count → August
“Dark money” is composed of organizations like 501(c)4 non-profits, which are groups that are not required to disclose their donors at all, since they are not supposed to have political activity as their primary purpose.
asserted
they → compose → purpose
(Those rules are often flouted in spirit, if not in practice.)
asserted
rules → flout → practice
The Brennan Center’s recent number crunching estimated that dark money groups account for an unprecedented 29% share of the top 40 donors and that $699m is largely untraceable.
asserted
m → estimate → donors
The landmark 2010 supreme court ruling Citizens United changed American campaign finance forever by allowing corporations and labor unions to spend unlimited sums on political expenditures.
asserted
corporations → change → expenditures
But rules against Super Pacs working closely with campaigns and candidates meant to counter the risk of corruption inherent in unlimited independent election spending are continually flouted and rarely enforced.
asserted
rules → work → spending
Trump himself has repeatedly referred to the Super Pac Maga Inc as being under his personal control and subject to his decision-making, which is against campaign finance law.
asserted
which → refer → law
Democrats are poised to regain control of the House and possibly the Senate, even as Republicans heavily outspent them, with polls showing minimal results from deluges of attack ads in competitive races.
uncertain
polls → poise → races
Exact figures for the disparity are hard to pin down, and are changing constantly.
asserted
figures → pin → disparity
For example, on Friday, with only days until the election, the former New York City mayor Michael Bloomberg dropped another $36m for Democratic candidates on top of the $80m he already committed.
asserted
he → drop → m
But best estimates show a steep Republican advantage in Senate race spending, and a narrower one in House races.
asserted
estimates → show → races
The surge in spending is a warning sign for elections ahead, Brennan’s Ian Vandewalker said: “We’ve long had a system of limits and disclosures, but that’s increasingly going away.”
asserted
that → warn → limits
Vanderwalker points to trends like new very wealthy industries like AI and cryptocurrency that have burst onto the scene, donating heavily to both parties, “clearly hoping for light or no regulation from the government, which is only going to increase”, and megadonors like Musk whose major spending “looks like a business investment”.
asserted
spending → point → investment
Bought by billionaires
Elon Musk’s ideological and personal business interests are well-documented, but other top megadonors fly below the radar.
asserted
megadonors → buy → radar
George Soros is one of the rare top 40 individual donors who give primarily to Democrats.
asserted
who → give → Democrats
Billionaires such as Wall Street’s Jeffrey Yass and the Uihlein family (owners of shipping giant Uline) are longtime Republican mega givers, focused on school choice and traditional ultraconservative causes, respectively.
asserted
Billionaires → focus → choice
Combined, the two families gave at least $260m in the 2026 cycle.
asserted
families → combine → cycle
Other megadonors include AI tycoons Marc Andreessen and Ben Horowitz, whose giving focuses on deregulation, advancing the crypto industry and electing pro-AI candidates.
asserted
giving → include → candidates
Israeli American businesswoman Miriam Adelson gave $67m this cycle and is known for advocating for far-right pro-Israel policies from the US government and exerting significant influence on Trump’s US-Israel policies.
asserted
Adelson → give → policies
Musk alone has given $483m so far in the midterms, a figure double what Soros gave to Democrats in 2022.
asserted
Soros → give → 2022
The richest person in the world has been focused on trying to help Republicans keep a Senate majority, particularly in a close Texas race.
asserted
Republicans → focus → race
Musk’s business empire and personal fortunes have been aided by his close relationship with the Republican candidate Ken Paxton.
asserted
empire → aid → candidate
A June supreme court decision allowing political parties to spend more in coordination with the candidates they support has helped the GOP inject big money from wealthy donors into small but crucial races, where Democrats enjoyed an advantage from raising more directly from smaller donors.
asserted
Democrats → allow → donors
Prior to the ruling, national party committees could only spend from $130,600 to $4,071,800 in coordination with an individual Senate candidate, and from $65,300 to $130,600 in coordination with an individual House candidate.
uncertain
committees → spend → candidate
But the court scrapped those limits.
asserted
court → scrap → limits
The shift means Republican committees have been able to raise more than $48m, dwarfing the $4m additional Democrats added, furthering the influence of big pocketbooks on smaller races that used to benefit from more grassroots local giving.
asserted
that → mean → giving
The past decade has also seen a major shift in the industries that influence elections with major spending.
asserted
that → see → spending
Labor, favoring Democrats, used to account for 14% of the top 40 midterm donors – now, it doesn’t even rank in the top 40, according to Brennan.
uncertain
it → favor → Brennan
Traditional finance interest giving has also declined in influence–from almost half of the top 40 donors in 2014 to only 15% this year.
asserted
giving → decline → %
New industries like crypto and artificial intelligence, and megadonors associated with them, are crowding out those traditional industries, as the scale of the big money gets bigger.
asserted
scale → associate → money
