A total of 1,013,162 managers used the chip on the Egyptian, smashing the previous record of 359,246 set by Harry Kane (£12.2m) last season.
Salah rewarded that faith in style, claiming 28 points in the Gameweek, with that trebled for his Triple-Captainers.
His heroics against Leeds mean he is on 207 points for 2021/22, becoming the first player in FPL history to record 200+ points in five successive seasons. He has surpassed the feats of Thierry Henry (2002/03 to 2005/06) and Frank Lampard (2003/04 to 2006/07).
DGW26 chips used
There were around 850,000 other chips deployed, with the 239,806 Bench Boosts activated being a record number in a Gameweek so far this season.
Salah was also the most-captained player, with more than 3m managers giving him the armband overall.

Manchester United's Cristiano Ronaldo (£12.4m) and Bruno Fernandes (£11.7m) completed the top three captains.
After the Portuguese pair's double-figure hauls in Double Gameweek 25, Fernandes continued his good form with a goal and an assist in Sunday's 4-2 win at Leeds. But Ronaldo was booked and finished with one point.
DGW26 most-captained by top 100
The leading 100 Fantasy managers overwhelmingly sided with Salah, with 97 members of this elite group trusting him with the armband.
Trent Alexander-Arnold (£8.5m) took second spot but it was a disappointing start to the Double Gameweek for his backers as he was left out of the squad to face Norwich. He then kept a clean sheet against Leeds for six points.
But though he came close to scoring in the Gunners' dramatic 2-1 win against Wolverhampton Wanderers on Thursday the England international was unable to add more than a point for his efforts.
DGW26 most transferred-in players

Salah was the No 1 transfer target ahead of the Double Gameweek 26 deadline, with nearly 1.5m adding him to their squads.
Only Ronaldo back in Gameweek 4 has been a more-popular acquisition in a Gameweek this term.
Joining Salah and Saka among the most-bought players was Raul Jimenez (£7.4m).
The Mexican was transferred in by more than 527,000 and produced an assist in his first match of the week, helping Wolves beat Leicester City 2-1 on Sunday. Like Saka, he added just one point in the loss at Arsenal.
DGW26 most transferred-out players
|Player||Transferred out by ('000s)||Pts|
An injury to Diogo Jota (£8.4m) resulted in his being shipped out by over 1.5m managers. The Portuguese missed both of Liverpool's matches.
Fernandes was the second most-sold player ahead of the deadline as many made a straight swap to Salah.
And despite amassing 66 points in eight matches prior to Double Gameweek 26, Kevin De Bruyne (£12.0m) was another makeweight in the clamour to move for Salah.
