Overview
Since January, the US and Israeli strikes on Iran have reshaped the regional landscape in ways that will take months, if not years, to fully understand. The human cost is serious, the diplomatic path is unclear, and the questions facing policymakers and peacebuilders are urgent.
Ploughshares is uniquely positioned to guide the nuclear field through these crises using lessons learned from our decades of experience and applying strategies to uncover new, longer-lasting solutions to the world’s greatest problem. Together, we can envision a new world order rid of nuclear threats. One where agreements, cooperation, and international standards are upheld.
A series of events so related that each one initiates the next is known as a chain reaction. Every year we gather leaders in our field, devoted partners, and new advocates to generate bold ideas and strategies to advance policies to reduce the threat of nuclear weapons. You—and every new ally you introduce to Ploughshares—represent critical innovators of change.
Please consider supporting the event with a sponsorship:
All Chain Reaction sponsors will receive recognition on all print and electronic event materials, onscreen during the program, on the Ploughshares website, and in the 2026 annual report. Sponsorships include admission for up to eight guests.
Sally Lilienthal Sponsor – $20,000+ A Sally Lilienthal Sponsorship honors the legacy of our founder. A gift of $20,000 allows us to make grants that respond to urgent needs, such as “fly-ins” so constituents can meet directly with congressional offices and advocate against dangerous nuclear legislation. Sally Lilienthal Sponsors are listed as co-chairs of the Host Committee and will receive verbal recognition during the program and VIP seating for you and your guests.
Advocate Level – $10,000 An Advocate level sponsorship helps educate and support the next generation working to eliminate nuclear weapons. For example, $10,000 is the stipend each Ploughshares Nuclear Futures Fellow receives to kickstart an innovative capstone project at their home organization. Advocates receive verbal recognition during the program and VIP seating for you and your guests.
Activist Level – $5,000 As an Activist, you support coordination activities to shift public opinion about nuclear weapons. For example, each of the four members of the Core Team for Ploughshares’ Stop the Nuclear Arms Race Roundtable receive a $5,000 honorarium from Ploughshares for their leadership of cross-organizational efforts to bolster our collective impact on the future of arms control and diplomacy. Includes VIP seating for you and your guests.
Analyst Level – $2,500 As an Analyst, you help to demonstrate the benefits of safer nuclear policies. For example, $2,500 covers the cost of an educational workshop about the legacy of nuclear weapons in a community harmed by America’s nuclear past. In addition, Analysts receive entry for eight guests to the event.
Other ticket options:
President’s Ticket – $1,000 Includes entry for eight guests.
Executive Director’s Ticket – $250 Includes entry for two guests.
