Laura Gillen leads Polymarket trader consensus at 72.5% implied probability to win the NY-04 Democratic primary on June 23, 2026, driven by her incumbency advantage after flipping the seat in the narrow 2024 general election, coupled with a dominant fundraising position—over $2 million raised and $1.5 million cash on hand as of late 2025, dwarfing challengers' negligible totals. Nicholas Sciretta trails at 17.5% and Taylor Darling at 10.7% amid no public polling, reflecting limited resources and name recognition for the field despite Darling's February announcement of a progressive challenge over Gillen's vote to fund ICE in a bipartisan spending package. With the filing deadline approaching on April 6, traders anticipate incumbency prevailing absent major scandals or endorsements.
