How Many of 34 AIPAC Endorsees Will Lose Primaries by August 4?

AIPAC spent more than $22 million in Illinois alone during the March 2026 primaries, and two of four endorsed Democratic House candidates still lost. That split record is exactly why this market sits at 47 percent for the 2-to-3 losses bracket. The math points to a narrow zone of underperformance for America’s most powerful pro-Israel lobby, and the remaining state primaries through August 4 will determine whether that projection holds.

The market question asks how many of a defined group of 34 AIPAC-endorsed candidates will lose their primaries before August 4, 2026, resolves. The 2-to-3 bracket carries a 47 percent implied probability, meaning 53 percent of the market expects a different outcome. Resolution is set for August 4, 2026, at 11:59 PM. Total lifetime volume sits at $1,072.

How the AIPAC Endorsee Primary Loss Contract Works

The YES outcome pays if exactly 2 or 3 of the 34 AIPAC-endorsed candidates on the defined list lose their primary races through August 4, 2026. Competing brackets cover 0-1, 4-5, 6-7, 8-9, and 10 or more losses. The market resolves based on certified primary results across all states with primaries in the window.

• 2-to-3 losses (YES outcome): 47 percent implied probability
• All other brackets combined (NO outcome): 53 percent implied probability

The NO outcome covers a wide range of possibilities. Fewer than 2 AIPAC endorsees losing would mean the lobby holds its ground across the board. Four or more losses would signal a broader anti-AIPAC wave sweeping multiple states before August 4. Either scenario pushes the market away from the 2-to-3 bracket.

Market Signals: Momentum and Conviction in a Thin Market

The momentum composite here deserves close attention. The 1-hour change is flat at zero, the 24-hour change is plus 1 percent, and the trend score sits at 9.55 out of 10. That combination reads as sustained buying pressure accumulating behind the 2-to-3 bracket, likely driven by the Illinois results confirming that AIPAC losses are happening but not yet cascading. The Illinois split decision gave traders a concrete data point to anchor around.

Lifetime volume of $1,072 with $10,967 in liquidity tells a different story about market depth. Volume is extremely low, which means individual trades can move the price sharply. Liquidity is relatively healthy compared to volume, but this remains a LOW-confidence market by any reasonable standard. Treat the 47 percent figure as a directional signal, not a precision estimate.

Key Factors

• Illinois primaries in March 2026 produced at least 2 confirmed AIPAC-endorsed losses, putting the market squarely inside the 2-to-3 bracket before later state primaries begin.
• North Carolina incumbent Valerie Foushee, an AIPAC-endorsed candidate, survived a narrow progressive challenge in March 2026, containing the loss total for now.
• AIPAC’s $22 million-plus Illinois spending produced only a 50 percent win rate, raising the question of whether diminishing returns accelerate in later-state primaries with less organizational infrastructure.
• The trend score of 9.55, combined with positive 24-hour movement, signals buying pressure building behind the 2-to-3 bracket as early results validate the range.
• The remaining primary calendar through August 4 includes states where anti-AIPAC progressive challengers have filed, keeping the upper brackets (4-5 and above) as live alternatives.

Lines Analysis: AIPAC’s Bracket Math

The 2-to-3 bracket has the clearest real-world anchor of any outcome in this market. Illinois delivered confirmed losses for AIPAC in the March cycle, and the Foushee survival in North Carolina held the number from jumping higher. The bracket leads the market because early results have validated its range, and the remaining primary calendar would need multiple simultaneous upsets to push the total past 3. Here’s what the market is missing: AIPAC’s track record in later primaries, specifically in lower-profile races in states without the organizational intensity of Illinois, has historically been stronger. The math on 2-to-3 losses is comfortable right now, but July and early August primaries add genuine variance.

The NO outcome at 53 percent is not a hedge. The NO outcome is a genuine alternative built on two very different scenarios. A total of 4 or more losses would require progressive challengers to replicate Illinois-style organizational energy in multiple additional states. A total of 0 to 1 loss would require AIPAC’s candidates to hold on everywhere else. Neither is implausible. The progressive infrastructure behind candidates like Zohran Mamdani in New York has demonstrated the capacity to move resources across state lines quickly.

Signals to Monitor

• New York primary results matter most: a second high-profile AIPAC-backed loss in New York would push the total toward 4 and pressure the 2-to-3 bracket from above.
• AIPAC spending announcements in July primaries will signal where the lobby perceives its most vulnerable endorsees and should be tracked for late-breaking price movement.
• Progressive challenger fundraising totals for any endorsed incumbent with a primary before August 4 are a leading indicator of whether the loss total accelerates.
• Dan Goldman’s primary outcome in New York will function as a market-moving event given his visibility and AIPAC backing.
• Any endorsee withdrawal or candidate disqualification before primary day would reduce the denominator and change the bracket math entirely.

The data favors the YES outcome modestly at 47 percent, but the thin volume means conviction is limited. The 2-to-3 bracket is ahead because the real world validated it early, not because traders have built a deep book behind it. The remaining primary calendar carries enough uncertainty to justify the 53 percent probability sitting across all other brackets combined.

LINES VERDICT

AIPAC Losses Land in the Middle

The early primary data confirms AIPAC endorsees are losing races, but not at a pace that breaks the 2-to-3 bracket. The lobby’s mixed Illinois record set the floor, and the remaining state calendar has not yet produced the cascade needed to push higher.

What the market says: The 2-to-3 bracket carries a 47 percent implied probability, meaning the market sees it as the most likely single outcome but not a consensus call. With thin volume and primaries still running through August 4, volatility in this market remains elevated and a single high-profile loss can reprice the brackets overnight.
