Record money, mixed returns

1. 1

   $366M through September. Musk was the cycle's biggest donor; Democrats won the House and the Senate, including in Texas, where he spent the most.

2. 2

   $54M through August. AIPAC's super PAC was the top outside spender; it lost in Michigan, CA-14 and NJ-11 and won in other races.

3. 3

   $316.7M against Proposition 40, versus about $10M from the union. On 4 Nov, the billionaire tax was trailing, with no race call.

4. 4

   20% to 30% of America PAC's paid door visits in Arizona and Nevada were flagged as suspect by its own app in 2024; the vendors disputed it.

5. 5

   1 point was El-Sayed's primary margin against more than $30M from AIPAC. No one has yet measured what the volunteer field did.

In 2026, a handful of donors put hundreds of millions of dollars into super PACs. On the night of 3 November, Democrats won the House and the Senate. The record money lost the most visible contests and won others, mostly away from the spotlight.

Two years of money

1. Oct 2024Leaked America PAC data show 20% to 30% of visits flagged as suspect in Arizona and Nevada (The Guardian). Wired reports paid canvassers on a quota of 1,000 doors a week.
2. Apr–May 2025Brad Schimel, backed by Musk's money, loses the Wisconsin Supreme Court election. In May, Musk says he will spend "a lot less" on elections.
3. 5 Feb 2026NJ-11 special primary: UDP spends more than $2.3M against Tom Malinowski, with ads about ICE and stock trading that never mention Israel. The winner is Analilia Mejia, Bernie Sanders's former political director, who was not targeted.
4. 17 Mar 2026Illinois primaries: AIPAC-linked money ($22M, according to Mondoweiss) wins in IL-2 and IL-8 and loses in IL-7 and IL-9, where Daniel Biss wins.
5. May–Jun 2026UDP wins away from the spotlight: more than $3M against Republican Thomas Massie (KY-4), who loses on 19 May, and more than $1M for Adrian Boafo (MD-5), who wins on 23 June. On 17 June, Proposition 40 qualifies with 980,438 valid signatures.
6. Jul 2026According to the New York Times, Musk authorizes America PAC to spend $100M to $120M on a new field programme in at least eight states, centred on the Senate.
7. 4–18 Aug 2026El-Sayed wins the Michigan primary by about one point despite more than $30M from AIPAC for Haley Stevens. On 18 August, Aisha Wahab wins CA-14 (53.1% to 46.9% with 95% counted) after more than $2.5M from UDP and allies.
8. Sep 2026Musk gives SLF $75M (9 Sep) and $83M (23 Sep); SLF passes it all to Texas PAC the next day. Outside-group ads in Texas pass $217M.
9. Oct 2026Wired counts $35.8M of America PAC field spending in the third quarter, with Blitz Canvassing holding the largest contract. In the first half of October, Musk puts another $76.8M into America PAC, according to IBTimes UK.
10. 3–4 Nov 2026AP calls the House for Democrats at 1:26 a.m. ET on 4 November. Talarico and El-Sayed win, and CBS projects Sherrod Brown the winner in Ohio: three states where Musk's money went in. Proposition 40 is trailing, with no race call.

Three layers

The money reached voters along three routes, with different results.

• Cheques for the airwavesMusk's $158M to SLF became TV, radio and digital ads through Texas PAC. Paxton lost.
• Outsourced door-knockingAmerica PAC paid firms to knock on Republican voters' doors in seven Senate battleground states and several House races. No one has published how many doors were knocked in 2026 or how well.
• Single-issue money in primaries and on the ballotUDP attacked Democratic candidates in primaries, almost never mentioning Israel, and lost the most visible ones. In California, billionaires funded the No on Proposition 40 and two competing measures, and were ahead in the count.

In the US, super PACs can raise and spend without limit as long as they do not give to candidates and disclose their donors to the FEC. In 2026 the election turned on tariffs, prices, immigration and the war with Iran, according to Roll Call. What was specific to the US in 2026 and may be missing elsewhere.

Platforms

Paid TV, radio and digital

SLF spent more than $159M on ads in Texas through Texas PAC, double Talarico's campaign outlay, according to AdImpact as cited by the Texas Tribune. By the end of September, outside groups had spent more than $217M on ads in that race.

Outsourced door-knocking

In July 2026, according to the New York Times as cited by theGrio, Musk authorized America PAC to spend $100M to $120M on a new field programme in at least eight states, focused on the Senate. Wired counted $35.8M on field in the third quarter, with Blitz Canvassing holding the largest contract and at least six other vendors.

Canvassing app (Campaign Sidekick)

Logs each visit with GPS and time. In 2024 its automatic unusual-activity report, which weighs speed and distance from the door, is what exposed America PAC's suspect visits.

Pass-through committees

Musk gave SLF $75M on 9 September and $83M on 23 September; each time, SLF moved the same amount the next day to Texas PAC, set up in August. According to Politico, cited by FactCheck.org, UDP routed more than 40% of its primary spending through pop-up or pass-through PACs.

Mobilize and volunteer events

In the week of 13 July, El-Sayed's campaign listed about 86 events on Mobilize; Haley Stevens's listed no in-person events, according to Defector.

California's ballot

Conflicting measures can cancel each other out: Proposition 40 would only take effect with more votes than 41 and 42, which its opponents put on the ballot and funded.

Local conditions

• Super PACs cannot give to candidates but can spend without limit on independent expenditures; donors appear in periodic FEC reports, often weeks after the money is spent (FactCheck.org).
• Democrats also had a lot of money: Talarico raised $64M from July to September, a quarterly record for a Senate candidate, and Senate Majority PAC raised $151M in the third quarter.
• A bad national environment for Republicans (tariffs, prices, immigration, the war with Iran), and mid-decade redistricting in Texas, North Carolina, Florida and Ohio that did not hold the seats, according to Roll Call.
• Shifting opinion on Israel: in June, 48% of voters and 66% of Democrats told Quinnipiac the US is too supportive of Israel, the highest level in nine years.
• In California, Governor Gavin Newsom, the teachers' union (CTA) and Planned Parenthood also opposed Proposition 40; the money was not alone.
• In May 2025, Musk had said he would spend "a lot less" on elections. He came back as the cycle's biggest donor.

No one published a manual. The mechanism below was reconstructed from FEC filings read by the press and from reporting on 2024 and 2026.

Three fronts

Concentrate on the Senate

Almost all of Musk's cheque to SLF went to a single race, Texas, and America PAC had put $24.8M of the $31M it had spent by 6 October into seven Senate races, according to Wired.

Outsource the contact

Instead of volunteers, contracted firms recruited paid canvassers to visit low-propensity Republican voters and push registration and early voting.

Attack on whatever issue works

UDP attacked Democratic candidates over immigration, stock trading or public safety, not over Israel, the interest that drives its donors.

The money cycle

From the cheque to the voter's door, according to the sources cited.

1. Give A megadonor writes an unlimited cheque to a super PAC.
2. Pass through The super PAC moves the money to a committee set up for one race (SLF to Texas PAC, the next day) or to pop-up PACs with other names.
3. Buy the airwaves TV, radio and digital, almost always negative ads against the opponent.
4. Hire the field Firms such as Blitz Canvassing recruit paid canvassers, often from out of state.
5. Demand volume In 2024, a quota of 1,000 doors a week, with hotel cover cut for anyone who missed it, at $30 an hour, according to Wired and Quartz.
6. Measure through the app Each visit goes into the app with GPS; the unusual-activity report flags entries logged far from the door or too fast.
7. Top up at the end Late money: more than $2.5M from UDP and allies from the start of August in CA-14, which voted on 18 August, and $76.8M from Musk to America PAC in the first half of October, according to IBTimes UK.

And again.

Part of what happened is campaign management that any side can use transparently. Another part produced suspect door data, precarious work and a voter backlash against outside money.

No one at America PAC, the Senate Leadership Fund or AIPAC has published an account of the 2026 strategy. The insider voices are spokespeople's statements to the press and the FEC filings. The rest was documented by journalists and analysts. On the volunteer side, the numbers come from the campaigns themselves.

• Elon Musk and America PAC

  Biggest individual donor of the cycle; Andrew Romeo is America PAC's spokesman

  Gave about $366M through September 2026, including $158M to the Senate Leadership Fund and $76M to America PAC, a breakdown confirmed by a spokesman for the group.

Five questions, each explained after you answer.

What applied in this case: federal campaign finance law, state rules, labour law and this site's ethical rules.

Super PACs and independent expenditures

They cannot give to candidates but can raise and spend without limit on ads for or against them; donors must be disclosed to the FEC (FactCheck.org).

Disclosure after the spending

Reports are filed quarterly and before the election. Musk's September donations only became public in October, and America PAC's pre-general report was filed on 22 October.

Payments to voters

In 2024 the Justice Department warned that America PAC's prizes for petition signers might be illegal; the details and the lawsuits are in this site's Trump 2024 case.

Voter data and canvassers' work

In 2024 Michigan's Secretary of State was investigating America PAC's data collection, and North Carolina's attorney general was investigating a website that collected data without registering voters. An election lawyer pointed to possible labour-law violations.

Competing measures in California

When two approved measures conflict, the one with more votes prevails. That is why Proposition 40 would only stand with more votes than 41 and 42.

Real people and real data only

For democratic campaigns: no invented door counts, paid canvassers with decent conditions who know whom they work for, paid creators disclosed, and the funder named on every piece.

The wave had national causes

Roll Call cites tariffs, immigration, prices and the war with Iran. There is no way to separate the effect of the money from the effect of the environment.

Democrats had money too

Talarico raised $64M in one quarter and Senate Majority PAC $151M. This was not money against poverty.

No America PAC scorecard yet

No one has published how many races the group won or lost. Alaska and Mississippi had not been called on 4 November.

Organized people don't always win

El-Sayed won the primary by about a point, Andy Levin lost in 2022, AIPAC money won in Illinois, Kentucky and Maryland, and Proposition 40 was losing.

Volunteer numbers are unverified

El-Sayed's 10,000 volunteers and 190,000 doors appear in Defector with no source given and no independent verification.

The quality of paid field work in 2026 is unknown

The suspect visits date from 2024 and were disputed. For 2026 there is no public data on doors, canvassers or audits.
